Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and in particular to a VOCs gas cooling device. Background Technology

[0002] Volatile organic compounds, commonly referred to as VOCs, are generally classified into several categories, including non-methane hydrocarbons (NMHCs), oxygenated organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organic compounds. VOCs participate in the formation of ozone and secondary aerosols in the atmosphere, significantly impacting regional ozone pollution and PM2.5 pollution. Most VOCs have unpleasant odors and possess toxic, irritating, teratogenic, and carcinogenic effects; benzene, toluene, and formaldehyde, in particular, can cause significant harm to human health. VOCs are important precursors to urban haze and photochemical smog, primarily originating from coal chemical, petrochemical, fuel and coating manufacturing, and solvent manufacturing and use processes. Currently, spray cooling is often required in VOCs gas treatment processes; however, existing spray devices are generally installed inside exhaust pipes, making disassembly and maintenance inconvenient, and lacking corresponding overflow channels. Therefore, this application proposes a VOCs gas cooling device. Utility Model Content

[0008] The beneficial effects of this utility model are:

[0018] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0019] In the first embodiment, the technical solution is as follows: When in use, the spray liquid enters the spray pipe 7 from the inlet pipe 4 and the metal hose 11, and then sprays out from the nozzle 9 on the spray pipe 7 to cool the VOCs gas passing through the exhaust pipe. The upper end of the maintenance square tube 2 is connected to the end cap 3 by bolts. Opening the end cap 3 facilitates the disassembly, assembly, and maintenance of the spray pipe 7 and related components. Furthermore, the spray pipe 7 is connected to the positioning component 6 by a positioning plug-in, which facilitates the quick disassembly and assembly of the spray pipe 7 and improves the efficiency of maintenance and installation. Furthermore, the present application also provides a drainage component 14. The buffer square tube 21 of the drainage component 14 can temporarily store the spray liquid to prevent the spray liquid from overflowing everywhere, and thus facilitate the timely discharge of the spray liquid through the drainage pipe 22.

[0020] In Example 2, based on Example 1, specifically, in use, the exhaust gas pipe 1 is used to transport VOCs gas to facilitate cooling of the VOCs gas. When cooling the VOCs gas, external spray liquid with a certain water pressure is sent in from the inlet pipe 4. Then, the spray liquid enters the spray pipe 7 from the metal hose 11 and is released from the nozzle 9. Multiple nozzles 9 are evenly arranged at the lower edge of the spray pipe 7, which facilitates the uniform and comprehensive coverage of the VOCs gas by the spray liquid, thereby cooling the VOCs gas.

[0021] When it is necessary to disassemble and repair components such as the spray pipe 7, the bolts can be unscrewed to separate the end cap 3 from the mating flange 20 above the maintenance square tube 2. After removing the end cap 3, the spray pipe 7 and other components can be maintained and disassembled from the maintenance square tube 2. When it is necessary to disassemble the spray pipe 7, the first connecting sleeve 12 and the second connecting sleeve 13 are firstly separated from the first threaded connector 5 and the second threaded connector 10, respectively. Then the metal hose 11 can be removed, and the spray pipe 7 can be disassembled and taken out for corresponding maintenance work. When disassembling the spray pipe 7, the external hoisting equipment can be connected to the lifting ring 19 to safely and forcefully remove the spray pipe 7 using the external hoisting equipment. The spray pipe 7 is connected to the positioning hole 16 on the support plate 15 by the positioning post 18 below the clamp 17, which facilitates quick and efficient disassembly and assembly of the spray pipe 7.

[0022] In Example 3, based on Example 2, to further prevent the spray liquid from overflowing in the exhaust pipe 1 after cooling the VOCs gas, a drainage component 14 is arranged. After the spray liquid is released from the nozzle 9, it can fall into the buffer square tube 21 directly opposite the nozzle 9 for temporary storage. The buffer square tube 21 is connected to the drain pipe 22. Opening the drain valve 23 can discharge the spray liquid temporarily stored in the buffer square tube 21 from the drain pipe 22 in a timely manner. An anti-clogging filter cartridge 24 is arranged at the inlet end of the drain pipe 22. The filter holes 25 on the anti-clogging filter cartridge 24 can effectively block impurities mixed in the spray liquid during spray cooling and prevent them from clogging the drain pipe 22.
