Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, specifically to a condensation and recovery device for low-concentration VOCs in industrial waste gas. Background Technology

[0002] Volatile organic compounds (VOCs) are a class of organic compounds that have high vapor pressure at room temperature and are easily volatilized. They are widely present in the waste gas emitted during industrial production processes. Currently, common methods for treating low-concentration VOCs include adsorption, combustion, and condensation.

[0003] The condensation method is based on the property that the saturated vapor pressure of substances varies at different temperatures. By cooling the waste gas to make it supersaturated, VOCs can be condensed and recovered. However, most existing low-concentration VOCs condensation and recovery devices do not filter the waste gas before the condensation operation. Industrial waste gas often carries a large number of particulate matter of various shapes and sizes, such as dust, debris, and other suspended impurities generated during the production process. These particulate matter enters the condensation system along with the waste gas. During the heat exchange between the waste gas and the condenser tube, the particulate matter easily accumulates on the surface of the condenser tube, which not only affects the heat transfer efficiency and reduces the condensation effect, but also causes wear on the condenser tube after continuous accumulation, shortening its service life and failing to meet current needs.

[0025] The pretreatment assembly 3 consists of a treatment box 301, a connecting plate 302, a filter plate 303, a fixing column 304, a sleeve column 305, a torsion spring 306, a fixing plate 307, a sliding rod 308, a spring 309, and a locking block 310. The treatment box 301 is fixedly installed on the side of the connecting pipe 205, and the air inlet pipe 4 is fixedly installed on the side of the treatment box 301. The connecting plate 302 is slidably installed inside the treatment box 301. A sealing ring is bonded to the bottom of the connecting plate 302, and a handle is fixedly installed on the top of the connecting plate 302. The sealing ring ensures the seal between the connecting plate 302 and the treatment box 301, and the handle facilitates the movement of the connecting plate 302. The filter plate 303 is fixedly installed on the bottom of the connecting plate 302. The fixing column 304 is fixedly installed on the top of the treatment box 301. The sleeve column 305 is rotatably installed on the surface of the fixing column 304, and the torsion spring 306 is sleeved on the surface of the fixing column 304. On the surface, one end of the torsion spring 306 is fixedly connected to the fixed post 304, and the other end of the torsion spring 306 is fixedly connected to the sleeve post 305. The torsion spring 306 is used to reset the sleeve post 305. The fixed plate 307 is fixedly installed on the surface of the sleeve post 305. The slide rod 308 is slidably installed inside the fixed plate 307. The spring 309 is sleeved on the surface of the slide rod 308.

[0026] During use, condensate is injected into the inlet pipe 202 from the outside. The condensate then flows through the condenser pipe 201 and is discharged from the outlet pipe 203. External industrial waste gas is introduced into the inlet pipe 4. The industrial waste gas passes through the treatment box 301 and the connecting pipe 205 to reach the condenser tank 1. Under the action of the condenser pipe 201, the industrial waste gas is fully condensed.

At the same time, the spring 309 is compressed and the torsion spring 306 is also compressed. When deformation occurs and the locking block 310 aligns with the slot at the top of the processing box 301, the slide rod 308 is released. Under the action of the spring 309, the locking block 310 can enter the slot at the top of the processing box 301. The connecting plate 302 and the filter plate 303 can be moved by the handle to clean the mesh of the filter plate 303. When the connecting plate 302 is placed into the processing box 301, the slide rod 308 is pulled to release the locking block 310 from the slot at the top of the processing box 301. Under the action of the torsion spring 306 and the spring 309, the locking block 310 can automatically enter the slot at the top of the connecting plate 302, connecting the connecting plate 302 and the processing box 301 together.
