Problems solved by technology

[0005] 1. The terminal steam trap or steam trap is easily blocked by rust impurities and cannot be drained automatically, causing liquid water to enter the subsequent dryer and affect the dew point quality of compressed air
If the adsorbent of the dryer is in contact with liquid water for a long time, it will pulverize and block the user's filter and equipment
[0006] 2. A large amount of compressed air will be discharged into the atmosphere along with the condensed water if the side is usually drained or manually emptied, resulting in a serious waste of energy

Abstract

The present invention relates to the field of machinery manufacturing gas purification process unit compressed air post-treatment zone equipment, particularly to a reflux type compressed air water discharging apparatus and a use method thereof. The reflux type compressed air water discharging apparatus comprises a gas-water separator (1) and an automatic steam trap (3), wherein both ends of a straight through water discharging pipe (23) are respectively connected to the water discharging port of the gas-water separator (1) and the water inlet of the automatic steam trap (3), the water discharging port of the automatic steam trap (3) is connected to a sewage discharging pipe (25), the sewage discharging pipe (25) is connected to an electromagnetic valve (42) in series, and a liquid level sensor (31) and a time control (32) are connected to the electromagnetic valve (42) through signal lines. The reflux type compressed air water discharging apparatus of the present invention has advantages of complete functions, convenient use, blockage avoiding, and energy saving.

Description

technical field [0001] The invention relates to the field of compressed air post-processing area equipment for gas purification process units in mechanical manufacturing, and specifically relates to a backflow compressed air drainage device and a method for using the device. Background technique [0002] In the compressed air production process, the atmosphere will produce a large amount of condensed water after being compressed and cooled by the air compressor, and the compressed air needs to be drained and dried before it can be used. At present, the industry generally adopts a gas-water separator plus a steam trap or a steam trap to achieve the purpose of discharging liquid condensate, and then absorbs the gaseous water vapor in the air through the dryer to meet the final process dew point standard for delivery. There are roughly two types of trap control methods, one is timing control discharge, and the other is liquid level control discharge. [0003] The Chinese paten...
