A gas-liquid separator for multiple heat pumps and its manufacturing method

Abstract

The invention discloses a gas-liquid separator for a multi-connected heat pump and a manufacturing method of the gas-liquid separator. The gas-liquid separator comprises a barrel, a gas inlet pipe, a gas outlet pipe and a liquid outlet pipe, a gas-liquid separation coiler is connected to the gas inlet pipe, the other end of the gas-liquid separation coiler faces the gas outlet pipe, and a liquid pocket is connected to the lower end of the gas-liquid separation coiler; and a thermostatic controller is installed on the barrel and is used for maintaining the temperature in the device. The manufacturing steps of the gas-liquid separator include that (1) physical design of the gas-liquid separator is carried out; (2) sample testing of the gas-liquid separator is carried out; (3) material preparation is made; (4) part machining is carried out; (5) part assembling is carried out; (6) welding is carried out; and (7) aftertreatment is carried out. According to the manufacturing method, the molding rate is high, the inferior-quality product rate is low, the product quality is high, and huge economic benefits can be brought to enterprises; and the gas-liquid separator is high in separation efficiency, thorough in gas-liquid separation and long in service life.

Description

technical field [0001] The invention relates to a gas-liquid separator, in particular to a gas-liquid separator for multiple heat pumps and a manufacturing method thereof. Background technique [0002] The gas-liquid separator can be installed at the inlet and outlet of the gas compressor for gas-liquid separation, gas-phase demisting after the condensation cooler on the top of the fractionation tower, gas-phase demisting of various gas washing towers, absorption towers and analytical towers, etc. The gas-liquid separator can also be used in various industrial and civil applications such as gas dust removal, oil-water separation and liquid removal of impurities. There are many separation methods used in the gas-liquid separator, the most widely used is gravity sedimentation, the principle of gravity sedimentation is: because the density of gas and liquid is different, when the liquid flows with the gas, the liquid will be affected by gravity, resulting in a The downward spe...

Problems solved by technology

[0004] 1. Inconvenient installation;

[0005] 2. Low manufacturing precision, high defective rate, poor product quality and short service life;

[0006] 3. The separation effect is poor, and the liquid droplets in the gas generally cannot be completely removed;

[0007] 4. The separation efficiency is low, and the general factory needs to be equipped with multiple gas-liquid separators, which increases the cost
