Bucket pump liquid supply distributed direct-cooling condensing unit for industrial VOCs tail gas recovery

Abstract

The invention discloses a barrel pump liquid supply distributed direct-cooling condensing unit for industrial VOCs tail gas recovery, relates to the technical field of crushing of friction materials, and aims at solving the problems that an existing condensing unit is prone to being affected by the external environment, the overall condensing effect needs to be improved, and meanwhile the manufacturing cost and the maintenance cost need to be reduced. Two fixed supporting frames are fixedly connected to the upper surface of the fixed bottom frame, a low-pressure circulating barrel is fixedly mounted in mounting grooves of the fixed supporting frames, an inner partition plate is arranged in an interlayer of the barrel wall of the low-pressure circulating barrel, a vacuum layer is arranged on one side of the inner partition plate, and the space of the other side of the inner partition plate is filled with heat preservation cotton. And a liquid conveying pipe is fixedly connected to the side surface of the bottom of the low-pressure circulating barrel, a second conveying pump is fixedly installed in a pipeline of the liquid conveying pipe, and a material returning pipe and an air suction pipe are fixedly connected to the side surface of the top of the low-pressure circulating barrel.

Description

technical field [0001] The invention relates to the technical field of refrigeration for VOCs tail gas recovery, in particular to a barrel pump liquid supply distributed direct cooling condensing unit for industrial VOCs tail gas recovery. Background technique [0002] VOCs are various organic compounds with a boiling point of 50°C to 260°C at room temperature. VOCs are involved in the formation of ozone and secondary aerosols in the pumping environment, which have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. VOCs It has uncomfortable characteristics and will cause great harm to human health. It mainly comes from the manufacturing process of coal chemical industry, petrochemical industry, fuel coatings, etc. In order to meet environmental protection requirements, VOCs need to be treated. The current treatment The method is to recover VOCs by condensation, and a high-efficiency condensing unit is required at this time. [0003] The existin...
