Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a tail gas device for a waste liquid storage tank. Background Technique

[0002] Waste liquid storage tanks play an important role in modern industrial parks and petrochemical plants, and are used for safely and effectively storing and treating waste liquid. These waste liquids often have characteristics such as corrosiveness, toxicity, or flammability and explosiveness, and are widely used in industries such as chemical engineering, pharmaceuticals, and electroplating. The tail gas device of the waste liquid storage tank is located above or near the waste liquid storage tank and is used for collecting and guiding the tail gas. Its design should ensure that it can effectively capture the tail gas and prevent it from leaking into the environment.

[0003] When the tail gas device treats the harmful gases in the waste liquid tank, it is necessary to draw the gas into the guiding pipe through a blower, and then filter the tail gas. Generally, the filtering material is in a fixed state. After long-term use, the side that first contacts the tail gas is fully utilized, while the side that finally contacts the tail gas is not well utilized. Since the harmful substances in the tail gas first contact one side of the filtering material and accumulate here, this side gradually becomes blocked. After being blocked, the resistance of the tail gas passing through the filtering material increases, and the filtering efficiency decreases. Some harmful gases may be discharged without being fully filtered, increasing the risk of environmental pollution. The filtering material on the side that finally contacts the tail gas fails to fully utilize its filtering ability due to insufficient utilization. This not only wastes the filtering material resources but also reduces the efficiency of the entire tail gas treatment system. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tail gas device for a waste liquid storage tank to solve the problems put forward in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A tail gas device for a waste liquid storage tank, comprising:

[0007] A storage tank, on the top of which a first guiding pipe and a second guiding pipe are provided, and the first guiding pipe and the second guiding pipe are connected through a filtering component;

[0008] A fixing plate, which is arranged on the top of the storage tank, and a group of guide rails are arranged on the fixing plate, and a support is slidably connected to the guide rails;

[0009] An installation pipe, which is located in the middle of the first guiding pipe and the second guiding pipe, and a filtering material is arranged in the inner cavity of the installation pipe, and a rotating shaft is fixedly connected to the middle of the filtering material through the installation pipe.

[0010] Preferably, the first guiding pipe is connected to the storage tank, and a supporting block is arranged on the outer surface of the second guiding pipe. The second guiding pipe is installed on the top of the fixing plate through the supporting block.

[0011] Preferably, the bottom of the installation pipe is fixedly connected to the support, and the filter material in the installation pipe is rotatably connected to the installation pipe, and the filter material is spherical.

[0012] Preferably, both sides of the installation pipe are open, and grooves are respectively arranged at the openings on both sides of the installation pipe.

[0013] Preferably, a first sealing strip is arranged on one side of each groove close to the opening.

[0014] Preferably, a first connecting pipe and a second connecting pipe are both slidably connected to the inner walls on both sides of the installation pipe.

[0015] Preferably, one side of the first connecting pipe away from the installation pipe is threadedly connected to the first guiding pipe.

[0016] Preferably, one side of the second connecting pipe away from the installation pipe is threadedly connected to the second guiding pipe.

[0017] Preferably, fixing blocks are fixedly connected to the sides of the first guiding pipe and the second guiding pipe close to the installation pipe.

[0018] Preferably, a second sealing strip is arranged on one side of each fixing block close to the installation pipe.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] By rotating the spherical filter material through the rotating shaft, each surface of the filter material can evenly contact the tail gas. When each surface of the filter material can evenly contact the tail gas, harmful substances and particulate matters in the tail gas are more likely to be comprehensively intercepted. This comprehensive contact method reduces the possibility of the tail gas bypassing the filter material, thereby improving the overall filtration efficiency.

[0021] By rotating the first connecting pipe and the second connecting pipe, the first connecting pipe and the second connecting pipe are gradually pressed against the first sealing strip and the second sealing strip, so that a closed passage is formed between the first guiding pipe, the second guiding pipe, the first connecting pipe and the second connecting pipe, preventing the tail gas from leaking into the external environment. The closed passage helps to optimize the flow path of the tail gas in the system, reduce eddy currents and turbulence, thereby reducing the flow resistance and enabling the tail gas to pass through the treatment system more smoothly.

[0032] Please refer to Figures 1-4 , an exhaust gas device for a waste liquid storage tank, comprising: a storage tank 1, a fixing plate 2 and an installation pipe 3,

[0033] Wherein, a first guiding pipe 101 and a second guiding pipe 102 are arranged at the top of the storage tank 1. The first guiding pipe 101 and the second guiding pipe 102 are connected through a filtering component. A blower is arranged at the end of the second guiding pipe 102. The blower generates suction force for the waste gas in the storage tank 1, so that the waste gas passes through the first guiding pipe 101 to be filtered by the filtering component, and the gas filtered by the filtering component then enters the next purification process through the second guiding pipe 102;

[0034] It should be noted that the fixing plate 2 is arranged at the top of the storage tank 1. A set of guide rails 201 are arranged on the fixing plate 2. A support 202 is slidably connected to the guide rails 201. By sliding the support 202 on the guide rails 201, the filtering component above it is driven to move left and right, facilitating the maintenance and replacement operations of the filtering component by the staff;

[0035] Furthermore, the installation pipe 3 is located in the middle of the first guiding pipe 101 and the second guiding pipe 102. The installation pipe 3 is composed of two hemispheres that can be opened. A filter material 301 is arranged in the inner cavity of the installation pipe 3. A rotating shaft 302 is fixedly connected through the middle of the filter material 301 in the installation pipe 3. The filter material 301 in the installation pipe 3 is rotatably connected to the installation pipe 3, and the filter material 301 is arranged in a spherical shape. By rotating the rotating shaft 302, the spherical filter material 301 is driven to rotate in the installation pipe 3, so that all surfaces of the filter material 301 are fully utilized. Among them, the driving force of the rotating shaft 302 can be provided by converting the thermal energy of the combustible part in the exhaust gas into mechanical energy for driving.

[0036] It should be added that the first guiding pipe 101 is connected to the storage tank 1. A support block 203 is arranged on the outer surface of the second guiding pipe 102. The second guiding pipe 102 is installed on the top of the fixing plate 2 through the support block 203. The inner wall of the support block 203 is fixedly connected to the second guiding pipe 102. The bottom of the installation pipe 3 is fixedly connected to the support 202. The bottom of the support block 203 is connected to the fixing plate 2 to prevent the displacement of the second guiding pipe 102 when operating on the installation pipe 3.

[0037] Furthermore, both sides of the installation pipe 3 are open, and grooves 206 are respectively arranged at the openings on both sides of the installation pipe 3. Sealing strips 207 are arranged on the sides of the grooves 206 close to the openings. On the inner walls of both sides of the installation pipe 3, a first connecting pipe 204 and a second connecting pipe 205 are slidably connected. The side of the first connecting pipe 204 away from the installation pipe 3 is threadedly connected to the first guiding pipe 101. On the sides of the first guiding pipe 101 and the second guiding pipe 102 close to the installation pipe 3, fixing blocks 208 are fixedly connected. Sealing strips 209 are arranged on the sides of the fixing blocks 208 close to the installation pipe 3. When the first connecting pipe 204 and the second connecting pipe 205 are rotated towards the first guiding pipe 101 and the second guiding pipe 102, the first connecting pipe 204 and the second connecting pipe 205 will gradually approach the sealing strip 207 and the sealing strip 209, promoting the formation of a closed passage between the first guiding pipe 101, the second guiding pipe 102, the first connecting pipe 204 and the second connecting pipe 205, and preventing the tail gas from leaking into the external environment.

[0038] Through all the above embodiments, the working principle of the present utility model is as follows:

[0039] During use, the filter medium 301 is placed in the installation pipe 3, and then the installation pipe 3 is pushed to make the installation pipe 3 slide on the guide rail 201 through the support 202. When the axis of the installation pipe 3 is aligned with the first guiding pipe 101 and the second guiding pipe 102, when the first connecting pipe 204 and the second connecting pipe 205 are rotated towards the first guiding pipe 101 and the second guiding pipe 102, the first connecting pipe 204 and the second connecting pipe 205 will gradually approach the sealing strip 207 and the sealing strip 209, promoting the formation of a closed passage between the first guiding pipe 101, the second guiding pipe 102, the first connecting pipe 204 and the second connecting pipe 205, and preventing the tail gas from leaking into the external environment. Among them, by rotating the rotating shaft 302, the position of the filter medium 301 is changed, so that each surface of the filter medium 301 can evenly contact the tail gas, avoiding waste caused by insufficient use of the filter medium 301.
