Abstract
Description
Technical Field
[0001] This utility model relates to the field of exhaust gas purification technology, specifically to an exhaust gas purification device for cyanuric acid synthesis reaction. Background Technology
[0002] Cyanuric acid is an important chemical raw material, widely used in disinfectants, flame retardants, water treatment agents, and other fields. Its synthesis is mainly achieved through the pyrolysis and condensation reaction of urea, which may produce ammonia, carbon dioxide, trace amounts of hydrogen cyanide, and particulate matter as exhaust gases.
[0003] According to CN213160134U, a device for treating chlorine tail gas from dichloroisocyanuric acid production is disclosed. This technology discloses a device comprising: "a device for treating chlorine tail gas from dichloroisocyanuric acid production, including a housing; an air inlet pipe connected to one outer surface of the housing; a drain pipe connected to the lower part of one outer surface of the housing near the air inlet pipe; a valve installed at the end of the drain pipe; an exhaust pipe connected to the upper surface of the housing; a ring-shaped infusion tank fixedly installed on the inner wall of the housing; several infusion channels connected to the inner side of the infusion tank; spray nozzles on both outer surfaces of the infusion channels; spray nozzles on adjacent infusion channels staggered at different heights; an infusion pipe extending to the outside of the housing connected to one outer surface of the infusion tank; and a demisting mechanism movably installed near the upper end of the inner wall of the housing." This device offers technical advantages such as "better purification effect and the ability to maintain the demisting effect for a longer period."
[0004] The exhaust gas produced by the cyanuric acid synthesis reaction is usually treated by a spray absorption tower. Pretreatment is required before treatment to prevent complex components in the exhaust gas from directly entering the absorption tower, which could lead to equipment blockage, corrosion, or reduced absorption efficiency. The dust removal equipment used in the current exhaust gas treatment system has certain limitations, especially the process of disassembling and replacing the filter element, which is quite cumbersome and causes inconvenience for daily maintenance and long-term stable operation. Utility Model Content

By fixing the composite catalytic filter element in the installation assembly through a fixing component, the replacement time of the composite catalytic filter element is significantly shortened, and the operating efficiency of the equipment is improved.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cyanuric acid synthesis reaction tail gas purification device, comprising a housing, wherein a filter mechanism is provided on the housing for tail gas filtration, the filter mechanism comprising:
[0007] The installation components include a frame fixed inside the box, with insertion holes at the front of both the top and bottom ends of the frame, into which a composite catalytic filter element is inserted and installed.
[0008] The fixing component includes a fixing bracket installed inside the front of the frame. A gear is rotatably installed in the middle of the fixing bracket. Guide rods are fixed at both ends of the fixing bracket. A rack is slidably installed on the guide rod. An insert rod is fixed on the rack.

[0013] Preferably, the mounting assembly further includes a sealing strip fixed to the inner wall of the frame.
[0014] Preferably, the gear meshes with racks at both ends for transmission. Beneficial effects
[0015] This invention provides a device for purifying the tail gas of a cyanuric acid synthesis reaction. Compared with the prior art, it has the following advantages:
[0016] 1. After the composite catalytic filter element is inserted into the frame, rotating the knob drives the gear to rotate. The gear, through the rack and pinion, drives the pin to retract into the fixing frame. This allows the fixing frame to be placed inside the front of the frame and locked onto the front of the composite catalytic filter element. Then, releasing the knob causes the spring to push the rack and pinion to extend outward and insert into the socket. This fixes the composite catalytic filter element in the mounting assembly, significantly shortening the replacement time of the composite catalytic filter element and improving equipment operating efficiency.
[0017] 2. The HEPA filter intercepts fine particles, and the UV lamp decomposes organic pollutants, forming a dual purification mechanism of physical filtration and photochemical oxidation. The sealing strip improves the airtightness of the composite catalytic filter after it is installed inside the sealing strip, preventing exhaust gas leakage and ensuring purification efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a cyanuric acid synthesis reaction tail gas purification device, including a housing 1, a filter mechanism 2 installed on the housing 1 for tail gas filtration, the filter mechanism 2 including:
[0025] The mounting component 21 includes a frame 211 fixed inside the housing 1. Insertion holes 212 are provided at the front of both the upper and lower ends of the frame 211. A composite catalytic filter element 22 is inserted and installed inside the frame 211.
[0026] The fixing component 23 includes a fixing frame 231 installed inside the front of the frame 211. A gear 232 is rotatably installed in the middle of the fixing frame 231. Guide rods 233 are fixed at both the left and right ends inside the fixing frame 231. A rack 234 is slidably installed on the guide rod 233. A plug rod 235 is fixed on the rack 234. A pin 236 is fixed at the other end of the plug rod 235 and cooperates with the plug hole 212. A spring 237 is installed on the guide rod 233. A knob 238 is fixed at the front end of the gear 232.
[0027] In this embodiment, after the composite catalytic filter element 22 is inserted into the frame 211, the rotating knob 238 drives the gear 232 to rotate. The gear 232, through the rack 234 and the insertion rod 235, drives the pin 236 to retract into the fixing frame 231. Thus, the fixing frame 231 can be placed inside the front end of the frame 211 and locked in front of the composite catalytic filter element 22. Then, the rotating knob 238 is released, and the spring 237 pushes the rack 234 and the insertion rod 235 to drive the pin 236 to extend outward and insert into the insertion hole 212. Thus, the composite catalytic filter element 22 is fixed in the mounting assembly 21 by the fixing component 23, which significantly shortens the replacement time of the composite catalytic filter element 22 and improves the operating efficiency of the equipment.
[0028] Specifically, the composite catalytic filter element 22 also includes limiting plates 239 fixed on the left and right sides of the rear end of the fixing frame 231.
[0029] In this embodiment, the positioning plate 239 ensures that the composite catalytic filter element 22 is installed in an accurate position.
[0030] Specifically, a HEPA filter 3 is installed on the right side of the inside of the housing 1, and a UV lamp 4 is installed inside the housing 1.
[0031] In this embodiment, the HEPA filter 3 intercepts fine particles, and the UV lamp 4 decomposes organic pollutants, forming a dual purification mechanism of physical filtration and photochemical oxidation.
[0032] Specifically, the front end of the box 1 is fixed with mounting brackets 5 on both the upper and lower sides, and a front panel 6 is installed on the front end of the box 1. The front end of the front panel 6 is fixed with buckles 7 on both the upper and lower sides and cooperates with the mounting brackets 5.
[0033] In this embodiment, it is convenient to disassemble and assemble the front panel 6 to maintain the interior of the housing 1.
[0034] Specifically, an air inlet 8 is fixed to the right end of the housing 1, and an air outlet 9 is fixed to the left end of the housing 1.
[0035] In this embodiment, the air inlet 8 is connected to the exhaust gas pipeline system, and the air outlet 9 is connected to the spray tower.
[0036] Specifically, the mounting component 21 also includes a sealing strip 213 fixed to the inner wall of the frame 211.
[0037] In this embodiment, the sealing performance of the composite catalytic filter element 22 after it is installed inside the sealing strip 213 is improved by the sealing strip 213, which prevents exhaust gas leakage and ensures purification efficiency.
[0038] Specifically, gear 232 meshes with racks 234 at both ends for transmission.
[0039] In this embodiment, when the gear 232 rotates, it can drive the racks 234 at both ends to move synchronously in opposite directions.
[0040] The working principle and usage process of this utility model are as follows: First, after the composite catalytic filter element 22 is inserted into the frame 211, the rotating knob 238 drives the gear 232 to rotate. The gear 232, through the rack 234 and the insertion rod 235, drives the pin 236 to retract into the fixing frame 231. Thus, the fixing frame 231 can be placed inside the front end of the frame 211 and locked in front of the composite catalytic filter element 22. Then, the rotating knob 238 is released, and the spring 237 pushes the rack 234 and the insertion rod 235 to drive the pin 236 to extend outward and insert into the insertion hole 212. Thus, the composite catalytic filter element 22 is fixed in the mounting assembly 21 by the fixing component 23, which significantly shortens the replacement time of the composite catalytic filter element 22 and improves the operating efficiency of the equipment.
