Description

Tar separator

Technical Field

The utility model belongs to the technical field of flue gas purification, and particularly relates to a tar separation device.

Background

High-temperature tail gas discharged by equipment such as industrial roasting furnaces and drying boxes used in the industries of chemical industry, catalysts, metallurgy and the like contains a certain amount of gaseous tar, and the tail gas is conveyed to tail gas treatment equipment along with a gas exhaust pipeline to be treated and then discharged. However, in the pipeline conveying process, the tail gas is gradually cooled by air, so that part of gaseous tar in the tail gas is condensed and attached to pipelines and tail gas treatment equipment and is difficult to remove, and the pipe orifice of the equipment is blocked to influence the normal operation of the equipment.

Meanwhile, the traditional tail gas treatment system only treats substances such as dust, hydrogen chloride, sulfur oxide, ammonia gas and the like in the tail gas, but cannot separate or treat tar. And a part of gas tar is discharged into the atmosphere along with the tail gas, so that the environmental pollution is caused, and the human health is harmed.
