In the case of manual operation, each device may be directly operated without using the control means 600.

  Operation | movement of the deodorizing apparatus comprised as mentioned above is demonstrated with the operation | movement procedure in the odor generating material acceptance installation 1. FIG. FIG. 5 is a schematic flow diagram showing a work procedure in the odorous product receiving facility 1 of the carry-in vehicle 500. 6 and 7 are explanatory diagrams of the deodorizing method in the receiving chamber 10-1, and FIGS. 8, 9, and 10 are explanatory diagrams of the deodorizing method in the receiving chamber 10-2. 6 to 10, the air supply fan 37 and the deodorizing fan 53 are always driven, and the total ventilation amount is constant.

  First, in FIG. 1, the carry-in vehicle 500 loaded with the odor generating material that has entered the odor generating product receiving facility 1 from the outside reaches the standby area 510 and sees the vacant display means 520 in the standby area 510. Since the vacant display means 520 displays the receiving rooms 10-1 and 10-2 that are currently vacant (not used by the other loading vehicles 500), the odor generating product loaded on the vacant display means 520 is settling the sand. In the case of scum, if there is an empty room in the receiving room 10-1, it moves to the receiving room 10-1, and if the odor generating substance loaded on itself is sludge (dehydrated cake), the receiving room 10-2. If there is a vacant room, it moves to the receiving room 10-2 (the front room 60) (steps 1-1 and 2-1 in FIG. 5).

  At this time, if the incoming vehicle 500 has not entered any of the receiving rooms 10-1 and 10-2 (including the front room 60), as shown in FIGS. 6 (a) and 8 (a), By opening the air supply damper 41 and closing only one escape damper 45, the external air (atmosphere) is supplied evenly from the air supply duct 35 to the receiving chambers 10-1 and the front chamber 60. At the same time, the exhaust damper 55 is opened, the receiving hopper damper 59 is closed, and in the case of the receiving chamber 10-2, the inter-room damper 67 is opened, so that each outside air supplied from the air supply duct 35 is received. It exhausts through the chamber 10-1, each front chamber 60, and the receiving chamber 10-2, and is ventilated. Note that the auxiliary damper 56 is always open during the following operation, and exhausts strong odor in the receiving hopper 25 little by little through the thin auxiliary conduit 58.

  On the other hand, if another incoming vehicle 500 has entered any of the other receiving rooms 10-1 and 10-2 (including the front room 60), the receiving room 10-1 in which the incoming vehicle 500 has not entered. , 10-2 are closed, and at the same time, the exhaust damper 55 is closed to restrict the ventilation of the room. At this time, since the auxiliary damper 56 is open, the receiving hopper 25 is ventilated.

  That is, in the present invention, since the total ventilation amount is constant, if any of the receiving rooms 10-1 and 10-2 is vacant, it is ventilated evenly, and any of the receiving rooms 10-1 and 10-2 is provided. When the carry-in vehicle 500 enters the room, the ventilation of the vacant room is stopped, and the ventilation of the room that has entered the room is given priority.

  Next, the case where the incoming vehicle 500 enters the receiving room 10-1 will be described first. That is, as shown in FIG. 6 (a), the incoming vehicle 500 first moves to a position just above the position detection sensors 29 and 29 in front of the vacant receiving chamber 10-1 in the reverse state and stops (step 1-1). . At this time, the position detection sensors 29 and 29 and the vehicle detection sensor 14 cause the control means 600 to detect that the incoming vehicle 500 is located at this position.

  Next, the receiving room identifying device 31 identifies whether the load of the incoming vehicle 500 that has entered is sedimentation / sediment or sludge (step 1-2). As a specific identification method, for example, the odor generating material conveyed by each incoming vehicle 500 is set in advance as to whether it is sand settling / sediment or sludge and is identified by the receiving room identification device 31 by this. In addition, the type of the odor generating product loaded on the carry-in vehicle 500 is identified. Any means may be used as long as it can identify the type of the odor generating product loaded on the carry-in vehicle 500.

  Next, when the receiving room identification device 31 confirms that the odor generating material conveyed by the carrying-in vehicle 500 is sand settling / sediment, the automatic door 13 is automatically opened, and the carrying-in vehicle 500 enters the receiving room 10-1. The approach is started (steps 1-3 and 1-4). In addition, when it is recognized that the odor generating material which the carrying-in vehicle 500 has conveyed is sludge, the carrying-in vehicle 500 moves toward the receiving chamber 10-2.

  Simultaneously with the opening of the automatic door 13, the air curtain device 15 is driven as shown in FIG. At the same time, the air supply damper 41 in this room is closed and the escape damper 45 is opened (the other dampers are the same as before), so that the supply air to the receiving chamber 10-1 is stopped and the exhaust from the exhaust pipe 54 is simultaneously discharged. continue. As a result, outside air flows into the room from the open receiving port 11, so that odor in the receiving chamber 10-1 hardly leaks from the receiving port 11 to the outside.

  Next, when the carrying-in vehicle 500 enters the receiving chamber 10-1 and stops right above the position detection sensors 27, 27, the automatic door 13 is automatically closed (step 1-5), and the receiving port 11 is shut off. In addition, the air curtain device 15 stops. At the same time, as shown in FIG. 6C, the air supply damper 41 is opened, the escape damper 45 is closed, the exhaust damper 55 is closed, and the receiving hopper damper 59 is opened. At the same time as the outside air is supplied, the air in the receiving hopper 25 is exhausted.

  Then, by turning on a manual switch (not shown) installed in the receiving chamber 10-1, the loading unit driving device 21 is driven, the opening / closing lid 19 is opened, and sand settling / sediment is loaded from the loading vehicle 500 into the loading port 23. (Step 1-6). At this time, the air in the receiving chamber 10-1 is sucked into the receiving hopper 25 from the charging port 23 and is exhausted to the outside through the receiving hopper conduit 57. Since the air in the receiving chamber 10-1 is sucked from the inlet 23, the odor in the receiving hopper 25 having the highest odor is less likely to leak to the receiving chamber 10-1. After the sand settling / sediment is charged into the charging port 23, the opening / closing lid 19 is closed by a manual switch.

When the open / close lid 19 is closed, as shown in FIG. 7A, the exhaust damper 55 is opened and the receiving hopper damper 59 is closed, whereby the air in the receiving chamber 10-1 is exhausted. At the same time, the ventilation time display unit 16 installed in the receiving room 10-1 displays how much ventilation is to be performed. For this ventilation time, the total ventilation air amount to be ventilated in the receiving room 10-1 is set in advance, and the control means 600 obtains the time for the total ventilation air amount by calculation each time. For example, the total ventilation flow rate by the air supply fan 37 and the deodorizing fan 53 is Q1 (m ³ / h), and n receiving chambers 10-1 and / or 10-2 including the receiving chamber 10-1 are included. If the total ventilation air volume in the receiving room 10-1 is Q2 (m ³ )
[Ventilation time] (h) = Q2 / {Q1 / n}
It becomes.

  That is, the ventilation time varies depending on the number of receiving rooms 10-1 and / or 10-2 that are ventilated. In addition, while the receiving room 10-1 is ventilated, the number of other receiving rooms 10-1 and / or 10-2 may change. In such a case, the remaining ventilation time is recalculated. The remaining time necessary for ventilation is changed and displayed on the ventilation time display unit 16. For example, if the necessary ventilation time is T minutes when only one room is used, a ventilation time of 2 × T is required if two rooms are used. Therefore, for example, if the necessary ventilation time is 10 minutes and only one incoming vehicle 500 enters the receiving room 10-1 or 10-2 at first, the ventilation time display unit 16 first displays “remaining 10 minutes”. Is displayed. If another incoming vehicle 500 enters another receiving room 10-1 or 10-2 when "5 minutes remaining" is displayed after 5 minutes, the first display is "10 minutes remaining". After that, “20 minutes remaining” is displayed on the subsequent ones. When another 10 minutes elapse, the first incoming vehicle 500 leaves and the display of the later one is changed to “5 minutes remaining”. In this case, any incoming vehicle 500 requires 15 minutes for ventilation.

  When the remaining ventilation time displayed by the ventilation time display unit 16 becomes 0 (step 1-7), the automatic door 13 is automatically opened (step 1-8) as shown in FIG. The air supply damper 41 is closed, the escape damper 45 is opened, the air curtain device 15 is driven, and the carry-in vehicle 500 is exited (step 1-9). At this time, no air is supplied into the receiving chamber 10-1, and only exhaust is performed from the exhaust pipe 54. Therefore, the odor in the receiving chamber 10-1 hardly leaks from the receiving port 11 to the outside. When the position detection sensors 29 and 29 and the vehicle detection sensor 14 detect that the incoming vehicle 500 has left, the automatic door 13 is automatically closed (step 1-10), and the receiving chamber 10-1 is shown in FIG. Return to the state.

  Next, a case where the incoming vehicle 500 enters the receiving room 10-2 will be described. In addition, when the description is overlapped with the case where the carrying-in vehicle 500 enters / leaves the receiving room 10-1, the detailed description is partially omitted. First, as shown in FIG. 8A, the carry-in vehicle 500 moves immediately above the position detection sensors 29 and 29 in front of the vacant front chamber 60 and stops (step 2-1).

  Next, when it is detected by the position detection sensors 29, 29 and the vehicle detection sensor 14 that the carry-in vehicle 500 is located at this position, the automatic door 63 is automatically opened as shown in FIG. Starts entering the front chamber 60 (steps 2-2 and 2-3).

  Simultaneously with the opening of the automatic door 63, the air curtain device 15 is driven as shown in FIG. At the same time, the air supply damper 41 is closed and the escape damper 45 is opened, so that supply of air to the front chamber 60 is stopped and at the same time, exhaust is performed from the exhaust pipe 54 via the inter-room damper 67. As a result, outside air enters the front chamber 60 from the open inlet 61, so that odor in the front chamber 60 hardly leaks from the inlet 61 to the outside.

  Next, when the incoming vehicle 500 enters the front chamber 60 and stops right above the position detection sensors 69, 69, the receiving room identification device 31 determines whether the load of the incoming vehicle 500 that has entered is sludge or sand. Identify whether it is a residue (step 2-4). When the receiving room identification device 31 confirms that the odor generating product carried by the incoming vehicle 500 is sludge (dehydrated cake), the automatic door 63 is automatically closed as shown in FIG. As shown in a), the automatic door 13 is automatically opened at the same time, and the incoming vehicle 500 starts to enter the receiving room 10-2 (steps 2-5 and 2-6). If it is recognized that the odor generating product conveyed by the carrying-in vehicle 500 is sedimentation / sediment, the carrying-in vehicle 500 leaves the vacant automatic door 63 as it is and moves toward the receiving chamber 10-1. .

  On the other hand, as shown in FIG. 8 (c), when the automatic door 63 is closed, the air supply damper 41 is opened and the escape damper 45 is closed, so that the exhaust pipe is passed from the front chamber 60 through the receiving chamber 10-2. At 54, exhaust is performed.

  Next, when the incoming vehicle 500 enters the receiving chamber 10-2 and stops right above the position detection sensors 27, 27, the automatic door 13 is automatically closed (step 2-7). At the same time, as shown in FIG. 9 (b), by closing the exhaust damper 55 and opening the receiving hopper damper 59, air supply to the front chamber 60 and the receiving chamber 10-2 is continued and at the same time the receiving hopper The exhaust of the odor in 25 is started.
