Description

Technical Field

[0001] This utility model relates to the field of VOCs technology, specifically to a chemical VOCs washing and treatment device. Background Technology

[0002] VOCs, or volatile organic compounds, refer to organic compounds that have a high saturated vapor pressure (greater than 13.33 Pa), low boiling point, small molecular weight, and are easily volatilized at room temperature under standard conditions. These substances are one of the major air pollutants and are commonly represented by VOCs, while total volatile organic compounds are represented by TVOC. It is important to note that VOCs do not refer to a specific pollutant, but rather to a collective term for a class of organic compounds with similar physicochemical properties.

[0003] Volatile organic compounds (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 are toxic, irritating, teratogenic, and carcinogenic; 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. Various equipment, including scrubbing towers, are required for VOC treatment.

[0004] Existing scrubbing towers are cumbersome to operate when opening and closing the access ports, making maintenance work through these ports inconvenient. Therefore, we propose a VOCs scrubbing and treatment device for chemical products. Utility Model Content

A connecting protrusion 11 is fixedly connected to the surface of the support shaft 10. Through the arrangement of the washing tower 1, exhaust port 2, inspection port 3, support block 4, fixed rod 5, support rod 6, hydraulic cylinder 7, piston rod 8, movable block 9, support shaft 10, connecting protrusion 11 and air inlet 16, it is convenient to drive the sealing block 12 to rise and fall, which is conducive to releasing the seal on the inspection port 3, and thus facilitates the maintenance work inside the washing tower 1. A sealing block 12 is fixedly connected to the bottom of the connecting protrusion 11, and a cylindrical gear 13 is fixedly connected to one end of the support shaft 10. A connecting rod 14 is fixedly connected to the top of the inspection port 3 on one side of the cylindrical gear 13. A fixing tooth block 15 is fixedly connected to the surface of the connecting rod 14. The arrangement of the cylindrical gear 13, the connecting rod 14, and the fixing tooth block 15 facilitates the rotation of the sealing block 12 while it is being raised and lowered, thereby improving the ease of opening and increasing the opening range. This ensures that personnel can effectively enter the interior of the inspection port 3. At the same time, the sealing block 12 facilitates the sealing of the inspection port 3, thereby preventing internal gas leakage while ensuring effective subsequent maintenance and improving the safety of washing.

[0021] In this embodiment, the support blocks 4 are distributed in an arc shape, and the diameter of the support blocks 4 is larger than the diameter of the inspection port 3, which facilitates effective support work for personnel during maintenance.

[0022] In this embodiment, the fixed rod 5 and the support rod 6 are vertically distributed, and the support rod 6 and the fixed rod 5 are an integrated structure, which facilitates the effective support of the hydraulic cylinder 7.

[0023] In this embodiment, the piston rod 8 extends into the inner wall of the hydraulic cylinder 7, and the piston rod 8 is slidably connected to the hydraulic cylinder 7, which facilitates the effective lifting and lowering of the piston rod 8.

[0024] In this embodiment, the connecting protrusion 11 is rotatably connected to the movable block 9 via the support shaft 10, and the connecting protrusion 11 and the sealing block 12 are an integrated structure, which facilitates the effective rotation of the sealing block 12 by the connecting protrusion 11.

[0025] In this embodiment, the sealing blocks 12 are distributed in a semi-circular shape, and there are two sealing blocks 12 symmetrically distributed on both sides of the inspection port 3. The circular structure formed by the two sealing blocks 12 is larger than the inner diameter of the inspection port 3, which facilitates effective sealing through the sealing blocks 12.

The piston rod 8 then drives the movable block 9 to rise and fall, which in turn drives the support shaft 10 to rise and fall. The support shaft 10 then drives the connecting protrusion 11 to rise and fall, which in turn drives the sealing block 12 to rise and fall. This releases the seal on the inspection port 3. Simultaneously, the support shaft 10 drives the cylindrical gear 13 to rise and fall. The cylindrical gear 13 meshes with the fixed gear block 15, causing it to rotate during the rising and falling process. This causes the cylindrical gear 13 to drive the support shaft 10 to rotate, which in turn drives the connecting protrusion 11 to rotate, which in turn drives the sealing block 12 to rotate. This improves the efficiency of opening the sealing block 12 and increases its opening range.
