Problems solved by technology

[0002] In the compressor unit of the current PTA production line, the air is compressed in four stages, and the cooler in the third stage compresses and cools the air to condense the water vapor in the air into water, which is discharged into the sewage tank. On the one hand, it will cause water loss. Waste, on the other hand, will increase the load of sewage treatment

Abstract

The invention provides a compressor unit condensate recovery system. The compressor unit condensate recovery system comprises a first-stage compressor, a first-stage cooler, a second-stage compressor, a second-stage cooler, a third-stage compressor, a third-stage cooler and a fourth-stage compressor which are sequentially connected. The system further comprises a condensate collection pool, a condensate delivery pump, a low-pressure steam pollution discharge flash tank, a condensate recovery delivery pump and a low-pressure steam pollution discharge flash tank cooler. Condensate discharge ports of the first-stage cooler, the second-stage cooler and the third-stage cooler are all connected to the condensate collection pool; the condensate collecting pool is connected to the low-pressure steam pollution discharge flash tank through the condensate conveying pump, and an outlet of the condensate conveying pump is connected to a low-pressure steam pollution discharge flash tank nozzle arranged at the top of the low-pressure steam pollution discharge flash tank; and a top outlet of the low-pressure steam pollution discharge flash tank is connected to the low-pressure steam pollution discharge flash tank cooler. The water vapor in the air is effectively cooled and then discharged out of the system to be collected and reused.

Description

technical field [0001] The invention relates to the technical field of air compression, in particular, to a compressor unit condensate recovery system. Background technique [0002] In the compressor unit of the current PTA production line, the air is compressed in four stages and a three-stage cooler. After compressing and cooling the air, the water vapor in the air is condensed into water and discharged into the sewage pool. On the one hand, it will cause water pollution. Waste, on the other hand, will increase the load of sewage treatment. SUMMARY OF THE INVENTION [0003] In order to solve the technical problems existing in the prior art, a compressor unit condensate recovery system is provided. The present invention effectively cools the water vapor in the air and discharges it out of the system for collection, and transports it to a low-pressure steam blowdown flash tank As the spray of the flash tank, the flash steam is effectively washed and transported to the rec...
