Gas-liquid separation for compressed air method and device

Abstract

An air-water separating process for compressed air features that compressed air is delivered via delivering pipe into cooling pipe in cooling drum to release its pressure as the diameter of cooling pipe is greater than that of delivering pipe, so its temp is lowered to make the pressure of water vapour close to saturated vapour pressure. The cooled air is delivered in air-water separator where its pressure is further released and its temp is further lowered, so the water vapour is condensed. Its apparatus is composed of a cooling drum with cooling pipe in it and an air-water separator.

Description

technical field [0001] The invention relates to a gas-liquid separation method and device for compressed air. Background technique [0002] When a general factory uses pneumatic tools on the production line, it usually injects high-pressure air into the pneumatic tools for use. However, high-pressure air is prone to produce moisture under high heat conditions. If the air injected into the pneumatic tool contains moisture, the moisture will easily remain in the pneumatic tool, causing the internal parts of the pneumatic tool to rust, and even affecting the quality of the pneumatic tool. and operational effects. [0003] Therefore, first let the high-pressure air flow through an air-cooled dryer, remove the moisture in the air with the help of the cooling and dehumidification effect of the air-cooled dryer, and then spray the dehydrated air into the pneumatic tool to be used to avoid air tools Damaged by the moisture contained in the air and increases its lifespan.

Problems solved by technology

[0006] In order to overcome the above-mentioned shortcomings of existing high-pressure air flowing through air-cooled air dryers to remove moisture in the air, the present invention provides a method and device for gas-liquid separation of compressed air, which uses water cooling and air pressure release The formed natural cooling phenomenon cools the high-pressure air without consuming power, and avoids the situation that the gas-liquid separation cannot be performed once the air-cooled dryer fails in the prior art. By increasing the diameter of the cooling pipe, Make the high-pressure air enter the large space from the small space, and then form a decompression phenomenon, let the air cool down due to decompression, and increase the residence time of the high-pressure air in the cooling barrel, coupled with the cooling effect of the coolant, so that in the multiple functions To improve the condensation effect of the cooling barrel, when the high-pressure air enters the gas-liquid separation barrel, the pressure will drop to the dew point temperature, causing a large amount of water vapor to condense, thus achieving an excellent gas-liquid separation effect
