[0001] This utility model relates to the technical field of distillation tower exhaust gas emission devices, and in particular to a chemical distillation tower exhaust gas emission device. Background Technology
[0002] With the development of the times and the continuous progress of social industrialization, the use of various equipment is essential for improving efficiency and quality in chemical production. However, the use of distillation towers generates a large amount of waste gas that pollutes the environment, thus requiring the use of emission devices for treatment.
[0003] To address this, patent CN211384267U discloses a waste gas emission device, including a wastewater tank, a top cover, an installation pipe, and a filter assembly. The wastewater tank has a groove at its top, and a top cover is installed directly above the groove. The top cover is fixedly connected to the wastewater tank by bolts. An installation pipe is fixedly connected to the top of the top cover, and a filter assembly is connected to the top of the installation pipe. The end of the filter assembly away from the installation pipe is connected to an exhaust pipe. The installation pipe is located directly above the top cover. The filter assembly includes a first connector, a connecting pipe, a second connector, a fixing pipe, and a filter plate. The connecting pipe has a cylindrical hollow structure, and its two ends are connected to the first connector and the second connector, respectively. Installation grooves for mounting the filter plate are provided on the connecting pipe at the locations of the first and second connectors. This waste gas emission device is reasonably designed, easy to use, and has the advantage of good filtration effect.
[0004] The aforementioned emission devices directly discharge waste gas into the sewage tank. However, they are not convenient for absorbing various harmful substances, and when the absorption is incomplete, it may lead to the leakage of harmful gases and thus cause environmental pollution. Therefore, they have certain limitations in their use. Utility Model Content

[0016] The present invention provides a chemical distillation tower exhaust gas emission device, the advantages of which are:
[0017] With a purification structure, a micro water pump is activated to extract the absorbent liquid from the storage tank through a water pipe, and then the liquid is discharged into the distribution seat through a connecting pipe. Atomizing nozzles are evenly installed at the bottom of the distribution seat to atomize the absorbent liquid and spray it out to absorb harmful substances in the waste liquid and let it fall downwards. In order to prevent incomplete absorption, an activated carbon layer is installed above the distribution seat to further absorb and treat harmful substances, thereby achieving the purpose of purifying harmful substances in the waste gas.
[0018] With a recycling structure, the collection box slides inside the chute and is positioned by the engagement structure formed by the L-shaped block and the locking groove. This prevents the collection box from shifting position inside the chute. Rotating the bidirectional screw aligns the two sets of L-shaped blocks, making it easy to pull the collection box out from inside the chute. This achieves the purpose of collecting and recycling harmful substances in the exhaust gas. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-5 The present invention provides a chemical distillation tower exhaust gas emission device, which includes an emission body 1 and an air inlet 2.
[0027] Reference Figures 1-3As shown, an air inlet 2 is provided on one side of the emission body 1. A purification structure 3 is installed on the outer wall of the emission body 1. The purification structure 3 includes a storage box 301 installed on the outer wall of the emission body 1. A micro water pump 302 is installed at the top of the storage box 301. A water suction pipe 303 is provided on one side of the micro water pump 302. A connecting pipe 304 is provided at the top of the micro water pump 302. A flow divider 305 is provided on one side of the connecting pipe 304. Atomizing nozzles 306 are evenly installed at the bottom of the flow divider 305. The water pump 303 extends into the storage tank 301 from the side away from the micro water pump 302, and the connecting pipe 304 extends into the discharge body 1 from the side away from the micro water pump 302. The diversion seat 305 is installed on the inner wall of the discharge body 1 and below the activated carbon layer 4. The diversion seat 305 and the storage tank 301 are interconnected through the micro water pump 302, the water pump 303 and the connecting pipe 304. The atomizing nozzles 306 are evenly distributed at the bottom of the diversion seat 305.
[0028] During the operation of a chemical distillation tower, a large amount of waste gas is generated, and its emissions pollute the atmosphere, thus requiring purification treatment. A purification structure 3 is installed, with an absorbent stored inside a storage tank 301. This allows the liquid to be pumped into a distribution seat 305 via a micro water pump 302 and water pipes. Atomizing nozzles 306 are evenly installed inside the distribution seat 305, atomizing the absorbent and spraying it into the discharge body 1. This absorbs harmful substances in the waste gas discharged into the discharge body 1 through the inlet 2, causing them to condense and fall into the collection tank 602 for collection. An activated carbon layer 4 is installed on the inner wall of the discharge body 1 above the distribution seat 305, further purifying the waste gas and greatly increasing the practicality of the device.
[0029] Reference Figure 1 , Figure 4 and Figure 5 As shown, an activated carbon layer 4 is installed on the inner wall of the emission body 1. An exhaust port 5 is opened on one side of the top of the emission body 1. A recovery structure 6 is opened at the bottom of the emission body 1. The recovery structure 6 includes a chute 601 opened at the bottom of the emission body 1. A collection box 602 is arranged inside the chute 601. A snap-fit groove 603 is opened at the top of the collection box 602. A reserved groove 604 is opened inside the emission body 1 above the chute 601. A bidirectional screw 605 is arranged inside the reserved groove 604. L-shaped blocks 606 are evenly arranged on the outer wall of the bidirectional screw 605. The collection box 602 is slidably connected inside the chute 601. The L-shaped blocks 606 are all threadedly connected to the bidirectional screw 605. One side of the L-shaped block 606 is arranged inside the snap-fit groove 603. The L-shaped block 606 and the collection box 602 form a snap-fit structure through the snap-fit groove 603.
[0030] The collection box 602 is used to collect the absorbent liquid containing waste gas. In order to facilitate its positioning and removal, a recovery structure 6 is provided. Rotating the bidirectional screw 605 aligns the two sets of L-shaped blocks 606, making it easy to disassemble the collection box 602 into the slide groove 601. After the L-shaped blocks 606 move into the locking groove 603, rotating the bidirectional screw 605 moves both sets of L-shaped blocks 606 to both sides of the locking groove 603, thus forming a locking structure. This makes it less likely for the collection box 602 to shift position during use, thereby greatly increasing the practicality of the device.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
