Description

Technical Field

[0001] This utility model relates to the field of toughening agent processing technology, and in particular to a purification and treatment device for waste gas generated during toughening agent processing. Background Technology

[0002] Toughening agents are additives that increase the toughness of materials. When a material is subjected to external impact, the toughening agent can absorb energy through its own deformation. For example, in plastic materials, the toughening agent molecular chains can stretch and bend under impact force, like many "small springs" installed inside the material. These "small springs" can convert impact energy into heat or other forms of energy, thereby preventing the material from cracking or slowing down the rate of crack propagation. Toughening agents can also prevent crack propagation through their own physical properties. For example, some toughening agents can form a "bridging" effect at the crack tip. When a crack forms, the toughening agent molecules span across the crack, acting like a bridge to bear part of the external force and prevent the crack from expanding further.

[0003] The production process of toughening agents typically generates waste gas, which requires a waste gas treatment device to reduce pollution. Publication number CN220047549U discloses a waste gas treatment device for the toughening agent production process, comprising: a base, a wastewater treatment mechanism on the top of the base, and a waste gas treatment component fixedly installed on the top of the base. In this invention, when in use, the waste gas enters the spray box through the inlet pipe and is sprayed by the waste gas treatment component. The treated wastewater flows through a conical water collection hopper, a drain pipe, and a threaded connecting pipe into a hollow box. In the wastewater tank, the wastewater sequentially passes through a filter screen, a molecular sieve, and an activated carbon block for filtration and dual adsorption treatment. The treated water is discharged through a drain pipe, thus achieving wastewater treatment and reducing pollution.

[0004] The existing technical solutions mentioned above have the following drawbacks: Since the spraying liquid is sprayed downwards from the nozzle to form strip-shaped fluids, there are gaps between adjacent strip-shaped fluids, which causes some exhaust gas to flow out through the outlet pipe without contacting the spraying liquid, reducing the exhaust gas treatment effect. At the same time, when it is necessary to replace the molecular sieve and activated carbon block and clean the filter screen, the exhaust gas treatment device needs to be stopped, that is, the toughening agent production work is stopped. This operation method reduces the production efficiency of the toughening agent. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a purification and treatment device for waste gas generated during toughening agent processing, which enhances the treatment effect of waste gas and improves the production efficiency of toughening agents.

[0006] To solve the above-mentioned technical problems, the present invention provides a purification and treatment device for waste gas generated during toughening agent processing, comprising: a stirring waste gas purification cylinder assembly and liquid filter box assemblies respectively disposed on both sides thereof. One side of each liquid filter box assembly is connected to an outlet pipe, and the top of each liquid filter box assembly is connected to an inlet pipe. The lower end of the stirring waste gas purification cylinder assembly is connected to a bottom-sealed drain pipe. A waste gas input pipe located obliquely above the drain pipe is connected to the stirring waste gas purification cylinder assembly. Flexible telescopic pipe assemblies that can be opened and closed are connected between the drain pipe and the inlet pipe on the liquid filter box assembly. The device also includes two pump assemblies, and the outlet pipe is connected to the stirring waste gas purification cylinder assembly via the pump assemblies.

[0007] By adopting the above technical solution, during use, an appropriate amount of treatment liquid is injected into the stirred exhaust gas purification cylinder assembly. The stirred exhaust gas purification cylinder assembly stirs the treatment liquid. The exhaust gas generated during the toughening agent processing enters the inner cavity of the stirred exhaust gas purification cylinder assembly through the exhaust gas inlet pipe. The exhaust gas flows upward in the treatment liquid, which treats the exhaust gas. Due to the irregular flow caused by the stirring of the treatment liquid, the treatment liquid and exhaust gas are in full contact, and the contact time between the exhaust gas and the treatment liquid is prolonged, thus enhancing the treatment effect of the treatment liquid on the exhaust gas. Since the treatment liquid leaves behind a considerable amount of impurities when treating the exhaust gas, a flexible telescopic tube assembly is used to remove these impurities. In the unobstructed state, the treatment liquid flows into the inner cavity of the corresponding liquid filter box assembly through the drain pipe, flexible telescopic pipe assembly, and inlet pipe. The liquid filter box assembly filters out impurities in the treatment liquid. The pump assembly operates to draw the filtered treatment liquid into the inner cavity of the stirred exhaust gas purification cylinder assembly, thereby realizing the recycling of the treatment liquid. Since the two liquid filter box assemblies can alternately filter the treatment liquid flowing out of the stirred exhaust gas purification cylinder assembly, even if it is necessary to clean the impurities in one of the stirred exhaust gas purification cylinder assemblies, the purification treatment equipment of this application can still work normally, improving the production efficiency of toughening agent.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the stirring type exhaust gas purification cylinder assembly includes a purification cylinder body and a cover plate connected to its upper opening. A rotating shaft is passed through the cover plate. A plurality of strip-shaped blades are connected at intervals on the lower outer circle of the rotating shaft. At least one circumferential scraper is connected between adjacent blades in the vertical direction. A motor is connected to the upper end of the rotating shaft. The drain pipe is connected to the lower end of the purification cylinder body. An exhaust gas input pipe is located obliquely above the drain pipe on the purification cylinder body. A plurality of support rods are connected at intervals on the outer circle of the purification cylinder body.

[0009] By adopting the above technical solution, the motor drives the rotating shaft to rotate, and the rotating shaft drives the strip blades and circumferential scraper to rotate in a circle. The strip blades and circumferential scraper stir the treatment liquid, causing the treatment liquid to flow irregularly. The treatment liquid and the exhaust gas are in full contact and the contact time is extended, which enhances the exhaust gas treatment effect.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the liquid filter box assembly includes a filter box body and a liquid distribution device disposed at its upper opening; the filter box body is provided with multi-stage filter layers; the liquid distribution device includes a sealed rectangular shell, and the lower plane of the sealed rectangular shell is provided with a plurality of circular holes at intervals.

[0011] By adopting the above technical solution, the sealed rectangular shell is connected to the liquid inlet pipe, and the treatment liquid flows into the inner cavity of the sealed rectangular shell. Through the setting of several round holes, the treatment liquid flows evenly into the inner cavity of the filter box body, that is, the treatment liquid is evenly distributed on the upper surface of the multi-stage filter layer. The multi-stage filter layer quickly filters the treatment liquid and removes impurities from the treatment liquid.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the multi-stage filter layer includes a placement frame, a coarse filter frame, a fine filter frame, and an activated carbon layer arranged sequentially from top to bottom. The lower surfaces at both ends of the coarse filter frame are respectively provided with sliding support plates fixed on the placement frame. The lower surfaces at both ends of the fine filter frame are respectively provided with the sliding support plates fixed on the placement frame. The lower surfaces at both ends of the activated carbon layer are respectively provided with the sliding support plates fixed on the placement frame. The activated carbon layer includes a hollow frame and a hollow plate connected to its upper opening. The inner cavity of the hollow frame is provided with activated carbon particles.

[0013] By adopting the above technical solution, the treatment liquid sequentially passes through a coarse filter frame, a fine filter frame, and an activated carbon layer. The coarse filter frame filters out large particulate impurities in the treatment liquid, the fine filter frame filters out small particulate impurities, and the activated carbon particles on the activated carbon layer adsorb and treat the organic compounds in the treatment liquid, thus achieving the purpose of filtering the treatment liquid. When the impurities on the coarse and fine filter frames need to be cleaned or the activated carbon layer needs to be replaced, the rack is removed, the coarse and fine filter frames are pulled out for cleaning, and the activated carbon layer is pulled out. The perforated plate is then opened to replace the activated carbon particles, improving the convenience of operation.

[0014] In a preferred embodiment, the present invention can be further configured such that: the flexible telescopic tube assembly includes a circular tube body, a flexible telescopic tube, and a switch valve disposed on the circular tube body; one end of the circular tube body is connected to the outer circle of the drain pipe, and the other end is connected to the end of the flexible telescopic tube; the end of the flexible telescopic tube away from the circular tube body is connected to the inlet pipe.

[0015] By adopting the above technical solution, the operation of the switch valve allows the flexible telescopic tube assembly to be in an open or closed state. The use of the flexible telescopic tube facilitates the opening of the inner cavity of the liquid filter box assembly and the cleaning of impurities in the inner cavity.

[0016] In a preferred embodiment, the present invention can be further configured such that: the liquid pump assembly includes a liquid pump body, a first pipe body is connected between the liquid inlet and the liquid outlet of the liquid pump body, and a second pipe body is connected between the liquid outlet of the liquid pump body and the stirring waste gas purification cylinder assembly.

[0017] By adopting the above technical solution, the pump body works to draw the filtered treatment liquid from the liquid filter box assembly through pipe one, and input the treatment liquid into the inner cavity of the stirred exhaust gas purification cylinder assembly through pipe two, so that the treatment liquid circulates between the stirred exhaust gas purification cylinder assembly and the liquid filter box assembly.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] 1. The waste gas flows upward in the treatment liquid, which treats the waste gas. As the motor drives the strip blades and circumferential scraper on the rotating shaft to rotate in a circular motion, the treatment liquid is stirred and produces irregular flow, which makes the treatment liquid fully contact the waste gas and prolongs the contact time between the waste gas and the treatment liquid, thereby enhancing the treatment effect of the treatment liquid on the waste gas.

[0020] 2. Since the two liquid filtration chambers can alternately filter the treatment liquid flowing out of the stirred exhaust gas purification chamber assembly, the purification equipment of this application can still work normally even when it is necessary to clean the impurities in one of the stirred exhaust gas purification chamber assemblies, thereby improving the production efficiency of toughening agents.

The rotating shaft 13 drives the strip blades 14 and the circumferential scraper 15 to rotate in a circular motion. The strip blades 14 and the circumferential scraper 15 stir the treatment liquid, causing the treatment liquid to flow irregularly. The treatment liquid and the exhaust gas are in full contact and the contact time is extended, which enhances the exhaust gas treatment effect.

[0038] The liquid filtration chamber assembly 20 includes a filter chamber body 21 and a liquid distribution device 22 with an opening at its upper end. The filter chamber body 21 is provided with multi-stage filtration layers 23. The liquid distribution device 22 includes a sealed rectangular shell 221.

The lower surface of the sealed rectangular shell 221 is connected to a rectangular limiting frame 223 adapted to the top opening of the filter chamber body 21. The sealed rectangular shell 221 is connected to the liquid inlet pipe 4. The treatment liquid flows into the inner cavity of the sealed rectangular shell 221. Through the arrangement of the plurality of circular holes 222, the treatment liquid flows evenly into the inner cavity of the filter chamber body 21, that is, the treatment liquid is evenly distributed on the upper surface of the multi-stage filtration layers 23. The multi-stage filtration layers 23 rapidly filter the treatment liquid and remove impurities from the treatment liquid.

[0039] The multi-stage filtration layer 23 includes a placement frame 231, a coarse filter frame 232, a fine filter frame 233, and an activated carbon layer 234 arranged sequentially from top to bottom.

One end of the circular tube body 71 is connected to the outer circle of the drain pipe 5, and the other end is connected to the end of the flexible telescopic tube 72. The end of the flexible telescopic tube 72 away from the circular tube body 71 is connected to the inlet pipe 4. Operating the switch valve 73 allows the flexible telescopic tube assembly 70 to be in an open or closed state. The use of the flexible telescopic tube 72 facilitates the cleaning of impurities in the inner cavity of the liquid filter box assembly 20, that is, it is convenient to remove the liquid distribution device 22.

A second pipe 83 is connected between the liquid outlet of the liquid pump body 81 and the stirred exhaust gas purification cylinder assembly 10. The liquid pump body 81 works by drawing the filtered treatment liquid from the liquid filter box assembly 20 through the first pipe 82 and inputting the treatment liquid into the inner cavity of the stirred exhaust gas purification cylinder assembly 10 through the second pipe 83, so that the treatment liquid circulates between the stirred exhaust gas purification cylinder assembly 10 and the liquid filter box assembly 20.

[0042] The implementation principle of this embodiment is as follows: During use, an appropriate amount of treatment liquid is injected into the stirring-type exhaust gas purification cylinder assembly 10. The stirring-type exhaust gas purification cylinder assembly 10 stirs the treatment liquid. The exhaust gas generated during the toughening agent processing enters the inner cavity of the stirring-type exhaust gas purification cylinder assembly 10 through the exhaust gas inlet pipe 6. The exhaust gas flows upward in the treatment liquid, and the treatment liquid treats the exhaust gas. Due to the irregular flow generated by the stirring of the treatment liquid, the treatment liquid and the exhaust gas are fully contacted, and the contact time between the exhaust gas and the treatment liquid is extended, thereby enhancing the treatment effect of the treatment liquid on the exhaust gas. The treatment liquid leaves a lot of impurities when treating the exhaust gas. A flexible telescopic pipe assembly 70 is operated to keep it in a smooth state. The treatment liquid flows into the inner cavity of the corresponding liquid filter box assembly 20 through the drain pipe 5, the flexible telescopic pipe assembly 70, and the inlet pipe 4. The liquid filter box assembly 20 filters out impurities in the treatment liquid. The pump assembly 80 operates to draw the filtered treatment liquid into the inner cavity of the stirred exhaust gas purification cylinder assembly 10, thereby realizing the recycling of the treatment liquid. Since the two liquid filter box assemblies 20 can alternately filter the treatment liquid flowing out of the stirred exhaust gas purification cylinder assembly 10, even if it is necessary to clean the impurities in one of the stirred exhaust gas purification cylinder assemblies 10, the purification treatment equipment of this application can still work normally, which improves the production efficiency of toughening agent.
