Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a multipurpose batch plant suitable for subjecting various raw materials to physical and / or chemical treatment to obtain relatively small amounts of products.

[Prior art]

For example, in the industry of performing physical treatments such as mixing of paints and chemical compositions, or in industries involving chemical reactions such as the manufacture of chemicals, dyes, pharmaceuticals, and catalysts, a large variety of relatively small products When it is intended to obtain a batch, naturally, a batch process is performed using a plurality of devices mainly including tanks. In order to efficiently respond to such a demand for high-mix low-volume production, a plant that can flexibly respond to various processes and various processes is required. The batch plants proposed so far include the following. 1) "Batch for batch production" (Japanese Patent Application Laid-Open No. 62-144745) is a method in which a container typified by a reactor moves and goes under a supply tank for raw materials and auxiliary materials, and receives necessary supplies there. After performing a predetermined process, the contents of the container are discharged by gravity or internal pressure, which is called "pipeless factory". 2) "Mobile tank type multipurpose batch system"("Chemicalequipment"
Similarly to the above-mentioned 1), the October 1987) is a system in which a moving tank is self-propelled to a position where a raw material is supplied or washed, and is intended to be pipeless. 3) The plant described in "Chemical Equipment", April 1987, employs a method in which an intermediate tank is moved, and uses an automatic carrier and a moving hoist. 4) "Mixed reaction processing device"
Adopts a method in which a processing container rotating about a rotating support receives a raw material from a raw material storage tank provided above the locus thereof, processes the raw material, and discharges the raw material to a lower receiving tank. All of the above-mentioned batch plants are limited to small-capacity plants because the equipment itself such as a reaction vessel and an intermediate tank moves. It will be readily appreciated that this is not practical, for example, considering self-propelled containers of 10 ton capacity. Alternatively, the handling amount is naturally limited due to the specified size of the self-propelled container itself. In addition, the container is provided with a supply of electric power or a heat medium for stirring and heating / cooling, or a restricting device, and there is also a technical problem of how to realize them in a self-propelled manner. If the contents of the container are dangerous goods under the Fire Services Act, the movement of the containers may be regulated by law.

[Problems to be solved by the invention]

It is an object of the present invention to overcome the above-mentioned problems, to provide greater flexibility in handling volume, to eliminate technical difficulties in equipment utilities and restrictions, and to avoid regulatory issues in handling hazardous materials. To provide a multipurpose batch plant.

[Means for Solving the Problems]

The multipurpose batch plant according to the present invention is shown in FIGS.
As shown in the drawing, the structure of one example is shown, consisting essentially of the following components: a) a cylindrical or polygonal steel tower assembler (2); b) this tower assembler (2) , A plurality of stages (1A, 1B, 1C) provided over several stages above and below, c) a plurality of raw material tanks (V101-107) provided on the upper stage (1A), d) below the raw material tank stage Equipment for physical or chemical processing (Rx
201) to 203,301), e) piping (3 to 5) fixed inside and / or outside of the tower-type assembler, and connection ports (32, 42, 52) of piping provided outside the tower-type assembler; A) a plurality of piping units having a flexible hose for detachably connecting the connection port of the raw material tank or the equipment and the connection port of the pipe; and g) means for supplying a raw material to the raw material tank. By connecting the piping unit between the raw material tank and any equipment and any equipment at the same or different stages, the raw material supplied to the upper stage is selected from the lower stage. A multipurpose batch plant configured to move by gravity to one or more of the equipment that has undergone the necessary physical or chemical treatment. The tower-shaped assembler (2) is suitably made of steel, and is suitably cylindrical or polygonal as shown in FIGS. 1 to 4. This is, as shown in FIGS. 5 and 6, the feed pipe (4) when the raw material is a liquid, the transfer pipe (5A, 5B) for the process liquid, the utility header (3) and the distribution pipe ( 31) Convenient for housing pipes such as bypass pipes (5C) and cables for power and control signals (6) inside and providing connection ports (32,42,52) for each pipe outside. It is. Part of the pipes and cables may be arranged along the outside of the assembler (1) depending on convenience. In FIG. 5, a part (5B) of the process liquid transfer pipe is provided outside. In FIG. 6, (11)
Is an access floor and (12) is an access hall. The raw material can be supplied to the raw material tanks (V101-107) by using a suitable pump if the raw material is liquid and by pumping it through piping, but in the case of powder, a tower type assembler should be used. A dedicated powder hopper and a powder feeder (both not shown) may be carried to the top of the assembler and distributed to each tank by an elevator (8). This method can also be applied to a liquid raw material, in which case it can be distributed using gravity, so that it is needless to say that a feeder is not required.

[Operation]

The functions required for a multipurpose batch plant are as follows. 1) The flexibility of the target and the amount to be handled is large. 2) The flexibility of the flow pattern is large, that is, the processes such as raw material preparation, reaction and crystallization can be arbitrarily combined. 3) Contamination. Minimized, specifically, the shape of the equipment is simple, there is no equipment that is not suitable for cleaning, there is no accumulation in the piping, 4) the piping is simple and the operation and maintenance are easy, and 5) The layout must not be unreasonable due to compliance with laws and regulations, typically the regulations for handling dangerous goods under the Fire Service Law described above. In order to meet the above requirements, the multipurpose batch plant of the present application has adopted the above-described structure. In the example shown, the assembler (2), which is a steel cylindrical tower, has 4
It has seven stages (1A, 1B, 1C, 1D), and the uppermost layer is provided with seven raw material tanks (V101 to V107). Transported and distributed. The middle stage has three medium to small reactors (Rx201 to Rx203), the lower one has a large reactor Rx301, and the tower type assembler (2) has a product receiver and If necessary, a separator (a centrifugal separator, a filter), a molding machine (a kneading extruder), a dryer and the like (all not shown) are provided. The coupling at the lower part of the raw material tank and the coupling at the arbitrary nozzle at the upper part of the reactor are connected by a piping unit having the above flexible hose, and the raw material is charged into the reactor. At this time, if necessary, as shown in the figure for the reactor (Rx203), the raw material is once charged into the measuring device M,
In some cases, a fixed amount is added. When the raw material is a liquid, the raw material is charged by connecting the coupling of the liquid raw material nozzle provided outside from the raw material header inside the assembler and the coupling of the nozzle at the top of the reactor with the piping unit. be able to. The reactor is equipped with a stirrer and, if necessary,
Attach a separator and a condenser. Each reactor also
Heating, warming, and cooling required depending on the reaction conditions with a jacket, by connecting the coupling of the nozzle provided outside from the utility header inside the assembler and the coupling of the utility nozzle of the jacket with the piping unit Do. That is,
Heating is performed by replacing the nozzles at the steam inlet and condensate outlet, warming is performed by replacing the nozzles at the hot water inlet and outlet, and cooling is performed by replacing the nozzles at the chiller water inlet and outlet with jackets. When the predetermined reaction is completed, the product in the reactor or the intermediate product is connected to the coupling of the discharge valve at the bottom of the reactor and the coupling of the nozzle provided outside from the bypass piping group inside the assembler by the piping unit. Then, it is taken out to a product receiver or, in some cases, sent to another reactor using a process liquid transfer pipe to perform a subsequent reaction step. If necessary in connection with the next operation, clean the inside of the system used for the above operation.

【The invention's effect】

In the multipurpose batch plant of the present invention, the space of the site can be greatly reduced as compared with the case where the equipment is arranged in a plane by the combination of the tower type assembler and the multilayer stage. Regarding the height, unlike the conventional method of installing equipment on each floor of the building, there is no interference between the floor height and the equipment layout, and there is no restriction on regulations for each floor of the building, and efficient use of space Is realized. By using the devices arranged in order from the upper layer to the lower layer, the contents can be moved by making the most of the gravity, so that pumps are unnecessary or minimal and the structure of the whole plant is simplified. It can easily respond to changes in the flow pattern, and can perform so-called "crossing operation" and "jumping operation" by using only gravity when viewed from the arrangement of equipment, so that the number of equipment at rest can be minimized. Efficient. The simplification of the structure also brings benefits to the piping, and avoids the so-called "trouble of the piping". By arranging the piping inside the assembler, there is no complicated piping around the equipment, which is convenient for operation and maintenance. The same applies to electrical and instrumentation cables. As described above, the flexibility of the handling target and the amount is large. In this batch plant, it is easy to carry out the initial construction with the number of stages or with a margin of space in each stage, and to later add equipment as necessary. That is, the expandability is high. In addition, it is easy to increase the number of plant lines.
