Description

Technical Field

[0001] The present application relates to the technical field of exhaust equipment, and in particular to an exhaust storage tank. Background Art

[0002] The most frequently used equipment in the chemical industry is the reactor. Most industrial chemical reactions will generate gas inside the industrial reactor during the reaction process. The gas generated by the reaction needs to be discharged from the reactor and transported to the gas treatment device for treatment. However, the amount of waste gas generated in the reactor during the chemical reaction is unstable. Generally, the exhaust volume of waste gas is large in a short period of time. In the existing industrial reaction equipment, the reactor is directly connected to the gas treatment device. During the reaction of the reactor, the waste gas generated in the reactor is directly transported to the gas treatment device for treatment. Since the exhaust volume of waste gas in the reactor is large and unstable in a short period of time, the gas treatment device processes too much gas in a short period of time. Most of the time, only a small amount of gas enters the gas treatment device, resulting in reduced treatment effect of the gas treatment device on the waste gas. At the same time, the gas treatment device needs to keep running, which has high energy consumption and great waste of resources. Utility Model Content

[0003] In order to solve the problems of high energy consumption, large resource waste and low processing efficiency of existing reactor exhaust treatment equipment in the prior art, the present application provides an exhaust storage tank.

[0004] An exhaust storage tank provided in the present application adopts the following technical solution: an exhaust storage tank, comprising a tank body, wherein a cloth bag assembly is arranged inside the tank body, wherein the cloth bag assembly divides the interior of the tank body into an upper cavity and a lower cavity, wherein the cloth bag assembly comprises a plurality of evenly arranged cloth bags, wherein the cloth bags are arranged inside the lower cavity, and one end of the cloth bag is connected to the upper cavity, and a first three-way joint and a second three-way joint connected to the upper cavity are respectively arranged at both ends of the tank body.

[0005] By adopting the above technical scheme, the first three-way joint on the tank body is connected to the nitrogen pipeline, and the second three-way joint below is connected to the reactor exhaust pipe. The exhaust gas generated during the reaction of the reactor is transported to the lower cavity inside the tank body through the pipeline for storage. When the exhaust gas needs to be discharged, nitrogen is transported to the upper cavity inside the tank body through the first three-way joint, and the nitrogen enters the cloth bag. The nitrogen is filled into the cloth bag to expand the cloth bag, so that the exhaust gas in the lower cavity is discharged by the pressure of the expansion of the cloth bag. When the exhaust gas is transported to the tank body again, the transportation of nitrogen is stopped, and the exhaust gas enters the lower cavity inside the tank body. The exhaust gas enters the lower cavity and the nitrogen is discharged from the cloth bag under the action of pressure, then enters the upper cavity and is discharged through the first three-barrel joint. When the exhaust gas needs to be discharged, nitrogen is transported to the tank body again, and this reciprocating process allows the exhaust gas generated in the reactor to be stored in the tank body and discharged for treatment when a certain capacity is reached, thereby improving the treatment efficiency and saving energy.

[0006] Optionally, the cloth bag assembly includes a mounting plate fixedly disposed inside the tank body, a plurality of mounting holes being evenly spaced circumferentially on the surface of the mounting plate, one end of the cloth bag being connected to the mounting hole, and a pressing block for pressing and fixing the cloth bag is disposed above the mounting hole.

[0007] By adopting the above technical solution, the cloth bag is inserted into the mounting hole, and the pressing block cooperates with the mounting plate to press and fix the edge of the cloth bag so that the cloth bag is connected to the upper cavity and the mounting plate and the cloth bag are sealed to prevent air leakage.

[0008] Optionally, a flange is extended outward from the edge of the pressing block, the pressing block is fixedly connected to the mounting plate by a plurality of bolts, and a plurality of air holes are opened in the middle of the pressing block.

[0009] By adopting the above technical solution, an air hole is arranged in the middle of the pressing block to facilitate gas to enter the bag through the air hole.

[0010] Optionally, sealing strips are provided between the edge of the cloth bag and the mounting plate and the pressing block.

[0011] By adopting the above technical solution, the sealing performance of the connection between the cloth bag, the pressing block and the mounting plate is improved by arranging the sealing strip.

[0012] Optionally, a partition is provided inside the lower cavity, the partition is provided below the cloth bag, and a plurality of through holes are evenly opened on the partition.

[0013] By adopting the above technical solution, when the exhaust gas generated in the reactor enters the tank body, the exhaust gas enters the lower cavity through the through holes on the partition. The partition is provided to allow the exhaust gas to enter the lower cavity evenly so that the bag is evenly pressurized. At the same time, the partition limits the bag to prevent the bag from over-expanding and causing damage due to excessive nitrogen pressure when nitrogen is input.

[0014] Optionally, a manhole is provided on one side of the tank body.

[0015] By adopting the above technical solution, a manhole is provided to facilitate operators to observe the interior of the tank.

[0016] Optionally, the cloth bag is arranged to be fan-shaped along the radial cross section and funnel-shaped along the axial direction.

[0017] By adopting the above technical solution, the bag is arranged in a fan shape along the radial section and in a funnel shape along the axial direction, so that the bag is evenly arranged inside the tank body and the bag is evenly pressurized when the exhaust gas is input.

The exhaust gas generated by the reactor is transported to the tank body for storage through a pipeline. When the exhaust gas is discharged, nitrogen is transported into the tank body. The nitrogen makes the cloth bag expand and discharges the waste gas out of the tank body. At the same time, the nitrogen and the exhaust gas are isolated from each other, thereby realizing the storage and discharge of the exhaust gas, so that the exhaust gas generated by the reactor can be collected and processed at the same time, and the gas treatment device does not need to be continuously operated, thereby improving the efficiency of exhaust gas treatment and reducing energy consumption.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] This embodiment discloses an exhaust gas storage tank.

[0032] Reference Figure 1 A gas storage tank includes a tank body 1, which is composed of an upper tank body 11 and a lower tank body 12 fixedly connected by a flange 4. A first three-way joint 2 is connected to the upper part of the upper tank body 11, and a second three-way joint 3 is connected to the lower part of the lower tank body 12. A bag assembly 5 is arranged inside the tank body 1, and the bag assembly 5 divides the inside of the tank body 1 into an upper cavity 6 above and a lower cavity 7 below.

[0033] Reference Figure 2 , Figure 3 and Figure 4The cloth bag assembly 5 includes a mounting plate 51 fixedly mounted at the connection between the upper tank body 11 and the lower tank body 12. A plurality of mounting holes 52 are evenly spaced along the circumferential direction on the mounting plate 51. The mounting holes 52 are arranged in a fan shape. A cloth bag 53 is inserted into the mounting hole 52. The radial cross-section of the cloth bag 53 is fan-shaped. The cloth bag 53 extends downward to the interior of the lower cavity 7. The cloth bag 53 is arranged in a funnel shape along the length direction. The upper end of the cloth bag 53 is connected to the mounting hole 52. A pressing block 54 is arranged at the connection. The shape of the pressing block 54 is consistent with the shape of the mounting hole 52. A flange 56 extends outward from the edge of the pressing block 54. The pressing block 54 is fixedly connected to the mounting plate 51 by a plurality of bolts 57. The bolts 57 are welded to the mounting plate 51. Sealing strips are arranged at the connection between the cloth bag 53, the pressing block 54 and the mounting plate 51.

[0034] Reference Figure 1 and Figure 5 A partition 8 is also provided inside the lower cavity 7 , and the partition 8 is provided below the cloth bag 53 , and a plurality of through holes 81 are evenly opened on the partition 8 .

[0035] The implementation principle of an exhaust storage tank in the present embodiment is as follows: the first three-way joint 2 above the exhaust storage tank is connected to the nitrogen pipeline, and the second three-way joint 3 below is connected to the reactor. The exhaust gas generated by the reactor during the reaction process is transported to the lower cavity 7 inside the tank body 1 through the pipeline and the second three-way joint 3 for storage. When the exhaust gas stored in the lower cavity 7 reaches the set capacity, nitrogen is transported to the inside of the tank body 1 through the nitrogen pipeline and the first three-way joint 2. The nitrogen enters the upper cavity 6 inside the tank body 1, and then enters the inside of the cloth bag 53 through the air hole 55 on the pressing block 54. The nitrogen causes the cloth bag 53 to expand. As the cloth bag 53 expands inside the lower cavity 7, the pressure generated by the expansion of the cloth bag 53 causes the exhaust gas inside the lower cavity 7 to be discharged through the second three-way joint 3 to the exhaust gas treatment device for treatment. By controlling the input nitrogen The rate of exhaust gas discharge is controlled so that the exhaust gas is evenly transported to the exhaust gas treatment device for treatment. When the exhaust gas generated in the reactor is transported to the inside of the tank body 1 again, the nitrogen is stopped from being transported to the inside of the tank body 1. After the exhaust gas enters the inside of the tank body 1, it evenly enters the lower cavity 7 through the through hole 81 on the partition 8, so that the pressure on the cloth bag 53 inside the lower cavity 7 is balanced. Under the pressure of the exhaust gas, the nitrogen in the cloth bag 53 moves upward into the upper cavity 6, and the cloth bag 53 contracts. The nitrogen is discharged to the outside of the tank body 1 through the upper cavity 6 and the first three-way joint 2 until the lower cavity 7 is filled with exhaust gas. When the exhaust gas is discharged again, the nitrogen is transported to the inside of the tank body 1 through the first three-way joint 2, so that the exhaust storage tank can effectively store the exhaust gas, so that the exhaust gas can be evenly transported to the exhaust gas treatment device for treatment.

[0036] In summary, in this application, the interior of the tank is divided into two chambers, and a shrinkable and expandable cloth bag is provided. The waste gas generated by the reactor is transported to the tank through a pipeline for storage. When the waste gas is discharged, nitrogen is transported into the tank, and the nitrogen makes the cloth bag expand to discharge the waste gas out of the tank. At the same time, the nitrogen and the waste gas are isolated from each other, thus realizing the storage and discharge of the waste gas, so that the waste gas generated by the reactor can be collected and processed at the same time, and the gas treatment device does not need to be continuously operated, which improves the efficiency of waste gas treatment and reduces energy consumption. Therefore, this application effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0037] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present application shall still be included in the protection scope of the present application.
