【００３５】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning an electrostatic precipitator suitable for an electric precipitator for a road tunnel for removing soot and dust containing, for example, diesel soot. . 2. Description of the Related Art Conventionally, an electrostatic precipitator (hereinafter referred to as “EP”) for removing particulate matter such as fine solid or liquid soot floating in gas or air by using electrostatic force. Abbreviated) has been widely used from purification of various industrial exhaust gases to indoor purification of homes, and has been effective. [0003] In such an EP, particularly in the case of removing soot containing diesel soot, pressurized air is blown toward the electrode portion during cleaning of the electrode portion, so that the dust attached to the surface of the electrode portion is deposited. Then, a cleaning method has been adopted in which air is blown into a dust collecting passage including the surface of the electrode portion to dry the electrode portion. FIG. 4 shows the configuration of such a conventional EP, in which an entrance damper 3 and an exit damper 4 are provided inside an entrance door 1 and an exit door 2, respectively. At the time of cleaning the electrode section 9 on the surface of which soot and dust containing diesel soot is deposited, the dampers 3 and 4 are closed, and the water in the water storage tank 10 is guided by the pump 11 to the cleaning pipe 7 through the electric valve 12 to be cleaned. It is sprayed from the nozzle 8 toward the electrode unit 9. Thereafter, when cleaning is completed, the motor-operated valve 12 is closed, the inlet damper 3 and the outlet damper 4 are opened, and the electrode portion 9 is opened.
Air-dry. [0005] In the conventional EP cleaning method as described above, it takes a long time to dry the surface of the electrode portion 9 after water washing, and furthermore, the blower is operated during drying. It must be continued, and the power loss is large. In addition, since diesel soot contains oil and carbon such as n-hexane extract and the like, spraying normal-temperature pressurized water completely removes soot and dust adhering and accumulating on the surface of the electrode portion 9. It is not possible. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to reliably remove soot and dust adhering to and depositing on an electrode portion and to perform ventilation drying after washing the electrode portion. An object of the present invention is to provide a method for cleaning an electrostatic precipitator capable of sufficiently reducing the time. Means for Solving the Problems The invention according to claim 1 is
After spraying pressurized water toward the electrode part of the electrostatic precipitator, and then spraying steam or hot water toward the electrode part to remove the dust deposited on the electrode part surface, the electrode part is blown by a blower. And drying the surface of the electrode portion by blowing air to the dust collecting passage including the dust collecting passage. According to such a method, since the cleaning is performed by spraying steam or hot water of about 70 ° or more after spraying the pressurized water once, soot and dust adhering and accumulating on the electrode portion can be more reliably removed. At the same time, the time required for ventilation drying after cleaning of the electrode portion can be greatly reduced. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows the configuration of an EP according to the embodiment, which is basically the same as that shown in FIG. 4, and therefore, the same portions are denoted by the same reference numerals and description thereof will be omitted. Thus, a steam generator 5 and a motor-operated valve 6 are provided instead of the water storage tank 10, the pump 11, and the motor-operated valve 12 shown in FIG. In the above-described configuration, when cleaning the electrode portion 9 on which soot and dust containing diesel soot is deposited on the surface, the inlet damper 3 and the outlet damper 4 are closed together, and the high temperature generated by the steam generator 5 is closed. The high-pressure steam is guided to the cleaning pipe 7 through the electric valve 6 and is sprayed from the cleaning nozzle 8 toward the electrode unit 9. After that, when the washing is completed, the motor-operated valve 12 is closed, the inlet damper 3 and the outlet damper 4 are opened, and the electrode section 9 is air-dried. As described above, since the surface of the electrode portion 9 is cleaned by spraying high-temperature and high-pressure steam on the electrode portion 9 instead of the pressurized water described in FIG. 4, most of the soot and dust adhering to the surface is accumulated. Can be reliably removed even if it is based on diesel soot containing oil or carbon such as an n-hexane extract. Furthermore, by spraying high-temperature and high-pressure steam instead of normal-temperature pressurized water to wash the electrode section 9, the time required for ventilation and drying of the electrode section 9 after washing can be greatly reduced. Power loss due to the operation of the blower during drying can also be reduced. In FIG. 1, the steam generator 5 generates high-temperature and high-pressure steam. However, the steam generator 5 is replaced with a hot water generator that generates hot water of, for example, 70 ° or more.
Even if hot water is sprayed on the electrode unit 9 instead of steam,
Similar effects can be obtained. (Second Embodiment) Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. FIG. 2 shows the configuration of the EP according to the embodiment, which is basically the same as that shown in FIGS. 4 and 1 above. Omitted. Thus, in addition to the water storage tank 10, the pump 11, and the electric valve 12 shown in FIG. 4, a steam generator 5 and an electric valve 6 are arranged in parallel. In the above configuration, when cleaning the electrode section 9 on the surface of which soot and dust containing diesel soot is deposited, the inlet damper 3 and the outlet damper 4
Are closed, and the water in the water storage tank 10 is first pumped.
1 guides the cleaning pipe 7 through the electric valve 12 and sprays it sufficiently from the cleaning nozzle 8 toward the electrode section 9. Thereafter, the motor-operated valve 12 is closed to end the spraying of the pressurized water to the electrode section 9, and the inside of the washing pipe 7 is drained by an air compressor (not shown). The high-temperature and high-pressure steam generated by the generator 5 is guided to the cleaning pipe 7 through the electric valve 6 and is sprayed from the cleaning nozzle 8 toward the electrode unit 9. When washing is completed in this way, the motor-operated valve 12 is closed, the inlet damper 3 and the outlet damper 4 are opened, and the electrode section 9 is air-dried. As described above, after sufficiently spraying the pressurized water, and additionally spraying high-temperature and high-pressure steam on the electrode portion 9 to clean the surface of the electrode portion 9, soot and dust adhering to the surface is deposited. Can be more reliably removed even if it is due to diesel soot containing oil or carbon such as n-hexane extract. Further, after the pressurized water at normal temperature, high-temperature and high-pressure steam is sprayed to wash the electrode portion 9 repeatedly, whereby
The time required for ventilation drying of the electrode unit 9 after washing can be significantly reduced, and the power loss due to the operation of the blower during drying can also be reduced. In FIG. 2, the steam generator 5 generates high-temperature and high-pressure steam. However, the steam generator 5 is replaced with a hot water generator that generates hot water of 70 ° or more, for example.
Even if hot water is sprayed on the electrode unit 9 instead of steam,
Similar effects can be obtained. (Third Embodiment) Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. FIG. 3 shows the configuration of the EP according to the embodiment, which is basically the same as that shown in FIG. 2 above. Therefore, the same portions are denoted by the same reference numerals and description thereof will be omitted. Thus, instead of the water storage tank 10 shown in FIG. 2, a cleaning liquid tank 13 storing a cleaning liquid is provided. In the above configuration, when cleaning the electrode section 9 on the surface of which soot and dust containing diesel soot is deposited, the inlet damper 3 and the outlet damper 4 are both closed, and the cleaning liquid in the cleaning liquid tank 13 is first pumped. 11 guides the cleaning pipe 7 through the motor-operated valve 12 and sufficiently sprays the cleaning nozzle 8 toward the electrode unit 9. After that, the motor-operated valve 12 is closed to stop spraying the cleaning liquid onto the electrode section 9, and water is drained from the pipe by an air compressor (not shown) provided in the cleaning pipe 7. The high-temperature and high-pressure steam generated by the generator 5 is guided to the cleaning pipe 7 through the electric valve 6 and is sprayed from the cleaning nozzle 8 toward the electrode unit 9. When washing is completed in this way, the motor-operated valve 12 is closed, the inlet damper 3 and the outlet damper 4 are opened, and the electrode section 9 is air-dried. As described above, after the cleaning liquid is sufficiently sprayed, the surface of the electrode portion 9 is cleaned by additionally spraying high-temperature and high-pressure steam on the electrode portion 9. Can be removed even more reliably even if it is due to diesel soot containing oil or carbon such as n-hexane extract. Furthermore, by spraying high-temperature and high-pressure steam after the cleaning solution to repeatedly clean the electrode portion 9, the time required for ventilation and drying of the electrode portion 9 after the cleaning can be greatly reduced. Power loss due to the operation of the blower during drying can also be reduced. In FIG. 3, the steam generator 5 generates high-temperature and high-pressure steam. However, the steam generator 5 is replaced with a hot water generator that generates hot water of 70 ° or more, for example.
Even if hot water is sprayed on the electrode unit 9 instead of steam,
Similar effects can be obtained. Further, a water storage tank 10 for storing water at normal temperature and a pump 11 ° are added in place of the steam generator 5,
Even if the normal temperature pressurized water is sprayed on the electrode portion 9 instead of the steam, the soot on the surface of the electrode portion 9 can still be more reliably removed. In addition, the present invention is not limited to the above-described first to third embodiments, and can be variously modified and implemented without departing from the gist thereof. According to the first aspect of the present invention, since the cleaning is performed by spraying steam or hot water of about 70 ° or more after spraying the pressurized water once, it adheres to the electrode portion. The deposited soot and dust can be more reliably removed, and the time required for ventilation drying after cleaning the electrode portion can be significantly reduced. [0035]
