Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, and particularly relates to a tail gas filtering device for chlorinated paraffin production with automatic gathering and centralized treatment. Background Art

[0002] Chlorinated paraffin is an organic compound, a chlorinated derivative of paraffin hydrocarbon, which has the advantages of low volatility, flame retardancy, good electrical insulation, low price, etc., and can be used as a flame retardant and an auxiliary plasticizer for polyvinyl chloride. It is widely used in the production of products such as cable materials, floor materials, hoses, artificial leather, rubber, etc. And it is also used as an additive in polyurethane waterproof coatings, polyurethane plastic runways, lubricating oils, etc.

[0003] The production process of chlorinated paraffin mainly includes several steps such as material preparation, paraffin chlorination, decolorization, purification, drying, and granulation. Tail gas containing harmful gases and other particulate matters will be generated during the processes of paraffin chlorination, decolorization, purification, etc. In industrial preparation, high-efficiency activated carbon is used for adsorption and chemical agents are used to absorb the harmful gases in the tail gas to complete the filtering treatment of the tail gas.

[0004] For such tail gas filtering and treatment devices used in chlorinated paraffin production, before using chemical agents to treat harmful gases, most of them first use a filtering structure such as activated carbon in the pipeline for exporting the tail gas to complete the absorption of particulate matters, and then spray a chemical agent mixture in the pipeline to make the chemical agent mixture fully contact with the tail gas and complete the reaction. At the same time, part of the harmful gases are dissolved in water and the water body is collected. In this process, since the particulate matters tend to fall under the influence of their own gravity when passing through the pipeline with the tail gas, when passing through the filtering structure, the particulate matters are easily accumulated in the lower part of the filtering structure, affecting the filtering effect of the lower part. At the same time, since the chemical agent mixture is sprayed in the pipeline, when the water vapor is sprayed, it is easy to mix with the toxic gas and contaminate the inner wall of the pipeline, corroding the inside of the pipeline and causing leakage of the pipeline. Summary of the Invention

[0005] The purpose of the present invention is to provide a tail gas filtering device for chlorinated paraffin production with automatic gathering and centralized treatment, so as to solve the problems that when particulate matters pass through the filtering structure in the pipeline with the tail gas, they tend to fall, the particulate matters are easily accumulated in the lower part of the filtering structure, affecting the filtering effect of the lower part, and at the same time, when spraying the chemical agent mixture in the pipeline, the water vapor is easily mixed with the toxic gas and contaminates the inner wall of the pipeline, corroding the inside of the pipeline and causing leakage of the pipeline.

[0043] The spray assembly 62 includes a liquid storage tank 621, a pressurized pipe 622 and a spray head 623. The liquid storage tank 621 is arranged at the end of the ceramic box 611. The liquid storage tank 621 stores chemical agents for exhaust gas reaction treatment.

Through the plurality of air blowing pipes of the blower 402, omnidirectional air blowing can be formed at the connection between the filter pipe 3 and the outlet pipe 2, helping the tail gas to uniformly pass through the filter pipe 3.

[0049] In this embodiment, the tail gas generated during production in the production main body 1 is led out to the filter pipe 3 through the outlet pipe 2, and the blower 402 is used to blow the tail gas through the filter pipe 3 to the other side. During the process, the tail gas first passes through the large ring pipe 51 part. The driving motor 532 is started to drive the extrusion turntable 533 to rotate. The rotation of the extrusion turntable 533 will squeeze the rotating ring 524 and the filter carbon plate 523, so that the filter carbon plate 523 rotates inside the large ring pipe 51 through the rotating shaft 522. At this time, when the tail gas passes through the filter carbon plate 523 to filter solid particles, the solid particles will not accumulate in the lower half of the filter carbon plate 523 due to their own gravity, keeping the filter carbon plate 523 in a uniform filtering state. The tail gas after filtering the solid particles continues to move forward along the filter pipe 3. At this time, inside the ceramic box body 611, the medicine mixed liquid for removing harmful gases in the tail gas is sprayed into the ceramic box body 611 by the spray head 623, enabling the tail gas to react with the medicine in all directions. During the process, the water vapor will disperse and adhere to the filter pipes 3 on both sides of the ceramic box body 611. And at this time, with the rotation of the rotating shaft 522, the linkage shaft 632 and the arc-shaped scraper 633 will be driven to rotate synchronously. When the arc-shaped scraper 633 located in the filter pipes 3 on both sides of the ceramic box body 611 rotates, it will scrape the water vapor on the inner wall of the filter pipe 3 through the arc-shaped edge and guide the water flow to the ceramic box body 611 through the arc edge, completing the reflux and collection of the water vapor. Finally, the tail gas after the treatment is led out from the other end of the filter pipe 3.
