Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a combustion treatment device for waste gas from steel structure painting. Background Technology

[0002] Coating is an important part of modern product manufacturing processes. The quality of rust-proof and corrosion-proof coatings is one of the important aspects of overall product quality. The appearance quality of a product not only reflects its protective and decorative performance, but is also an important factor in its value.

[0003] According to CN211659601U, a steel structure painting exhaust gas treatment device is disclosed. This technology discloses a technical solution such as "a steel structure painting exhaust gas treatment device, including a metal shell and a reaction tower, wherein the metal shell is provided with a lifting slide rail". It has the technical effect of "the hydraulic telescopic rods set on both sides of the metal shell can be extended and retracted to push the guide hood for lifting and adjustment. Through the cooperation of the lifting pulleys set on one side of the guide hood and the metal shell, the distance between the guide hood and the spraying equipment can be adjusted according to the collection needs of the exhaust gas during the collection and treatment of steel structure painting exhaust gas. This not only meets the exhaust gas collection needs under various adjustments, but also greatly improves the work efficiency of exhaust gas collection and enhances the exhaust gas collection effect. Under the adsorption drive of the induced flow fan, the exhaust gas is purified and filtered by the mutual filtration of the paint mist filter and the activated carbon adsorption filter, respectively, effectively improving the work efficiency and exhaust gas purification effect".

[0004] After combustion treatment, the exhaust gas from steel structure painting still requires further purification to meet environmental emission requirements. However, in actual operation, insufficient gas-liquid contact time leads to incomplete reaction of the exhaust gas in the packing layer, severely affecting the treatment effect. Furthermore, the dust removal equipment used in existing exhaust gas treatment systems has significant design flaws, particularly the complex disassembly and replacement process of the filter elements, which not only increases the difficulty of daily maintenance but also poses a potential threat to the long-term stable operation of the system.

Limiting grooves 123 are fixed at both ends of the frame 121 and cooperate with the limiting frame 113. Limiting strips 124 are fixed at both ends of the bottom of the drain hopper 112.

[0027] In this embodiment, during the installation of the frame 121 into the housing 111, the limiting groove 123 cooperates with the limiting bracket 113 to limit and prevent deviation. Then, the cover plate 115 is closed, and the closed cover plate 115 is fixed by the first pin 118 cooperating with the first insertion hole 117. At the same time, the cover plate 115 presses the frame 121 downward through the pressure strip 116, thereby fixing it in the housing 111. When the cover plate 115 is opened, the fixing of the frame 121 is automatically released, which facilitates maintenance and replacement.

[0028] Specifically, the main component 11 also includes limiting holes 114 at both ends of the top of the drain hopper 112, which cooperate with the limiting strip 124.

[0029] In this embodiment, after the frame 121 is installed inside the housing 111, the limiting strip 124 is inserted into the limiting hole 114 for positioning, ensuring accurate positioning of the filter component 12 during installation, effectively preventing component displacement, and improving the stability of system operation.

[0030] Specifically, the main component 11 also includes a slanted frame 119 fixed inside the housing 111, and the slanted frame 119 is inclined in the housing 111.

Several nozzles 1112 are installed on the water supply pipe 1111.

[0031] In this embodiment, the inclined arrangement of the packing layer 1110 and the water supply pipe 1111 optimizes the gas-liquid contact effect and extends the waste gas treatment time. At the same time, the parallel arrangement of the water supply pipe 1111 and the nozzle 1112 ensures uniform liquid distribution and significantly improves the purification efficiency.

An exhaust pipe 4 is connected between the upper end of the combustion tower 2 and the air outlet 1117. A chimney 5 is installed on the left side of the purification box 1, and a fan 6 is connected between the lower end of the chimney 5 and the air inlet 1116.

[0036] The working principle and usage process of this utility model are as follows: First, during the installation of the frame 121 into the housing 111, the limiting groove 123 cooperates with the limiting bracket 113 to limit and prevent deviation; after the frame 121 is installed into the housing 111, the limiting strip 124 is inserted into the limiting hole 114 for positioning to ensure accurate positioning of the filter assembly 12 during installation; then the cover plate 115 is closed, and the closed cover plate 115 is fixed by the first pin 118 cooperating with the first insertion hole 117. At the same time, the cover plate 115 presses the frame 121 downward through the pressure strip 116, thereby fixing it in the housing 111. At the same time, when the cover plate 115 is opened, the fixing of the frame 121 is automatically released, which facilitates maintenance and replacement.

[0037] Furthermore, by employing an inclined packing layer 1110 and a water supply pipe 1111, the gas-liquid contact effect is optimized, and the waste gas treatment time is extended. At the same time, the parallel water supply pipe 1111 and the nozzle 1112 ensure uniform liquid distribution, significantly improving the purification efficiency.
