Description

Technical Field

[0001] The utility model relates to the technical field related to chemical production and processing, in particular to a guided filtering type tar filter. Background Art

[0002] Tar is a complex mixture of highly aromatic hydrocarbons that is liquid and viscous at room temperature. It is produced in coal chemical production, biomass power generation, and the catering industry. The hazards it poses can cause blockage and corrosion in downstream equipment, including pipelines, vents, valves, and instrumentation, impacting production and hindering normal operation. Typically, electric tar collectors or conventional filtration devices are used to remove the tar.

[0003] After extensive searching, I discovered Chinese patent publication number CN 217593963U, which discloses a novel tar filter comprising a filter body, flange, flange cover, baffle, and filter screen. The device utilizes a baffle to filter out large tar particles, allowing smaller tar particles to enter the squeeze pump, where they are crushed and then continue settling and separation in the tar-ammonia pre-separator. This solves the problem of squeezing pumps being prone to clogging and damage, ensuring normal separation operations and improving production efficiency.

[0004] In summary, the guiding performance of the baffle between the air inlet and the air outlet of the existing tar filter is relatively poor, which makes it difficult for large tar particles to be blocked and settle on the filter below.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a guided filtering tar filter to make it more valuable for industrial use. Utility Model Content
