Gas condensation recovery device

Abstract

The invention relates to a gas condensation recovery device. The gas condensation recovery device structurally comprises an A-path catcher, a B-path catcher, a recovery tank, an A gas-liquid separator, a heat regeneration catcher and a refrigerating system connected with the A-path catcher, the B-path catcher and the heat regeneration catcher. The gas condensation recovery device has the advantages that the structure is compact and reasonable, operation and use are convenient, and condensation recovery of low-dew-point gas can be provided; a single refrigerating system is matched with two paths of catcher and is flexibly switched through valves, so that continuous operation of condensation recovery is ensured; the heat regeneration catcher is arranged, unrecovered low-temperature gas is heated after passing through a heat regenerator, when the unrecovered low-temperature gas reaches a discharge outlet, the temperature of the gas can basically reach the environment temperature, and theicing phenomenon caused by direct discharge of the low-temperature gas is avoided; a heat source of the heat regeneration catcher adopts a waste heat regeneration mode, waste heat at an outlet of a condenser of the refrigerating system is utilized, when the heat of the condenser is insufficient, part of hot air is directly bypassed through an electromagnetic valve and an air conditioning valve atthe front end of the condenser to enter the heat regenerator, other heat sources do not need to be additionally connected, and the energy-saving purpose is achieved.

Description

technical field [0001] The invention relates to a gas condensation recovery device. Background technique [0002] The condensation of gas is usually carried out in a low temperature or high pressure environment. Considering operability and economy, low temperature condensation is generally used for recovery. However, it is difficult to avoid frosting at low temperatures, especially in environments with high air humidity, defrosting tends to be very frequent. [0003] In order to ensure the continuity of the gas condensation recovery process, two sets of condensation recovery devices are required in the prior art, and when one set enters defrosting, the other can continue to operate. However, this greatly increases the user's initial investment and later maintenance costs. At the same time, the two sets of equipment occupy an increased area, which cannot meet the space requirements of users.
