Combined cyclone baffling large-caliber gas-liquid re-separation device for gas compressor

Abstract

The invention discloses a combined cyclone baffling large-caliber gas-liquid re-separation device for a gas compressor. Cyclone fins (3) are circumferentially fixed on inner walls of a shell (1) on the lower side of a position, which is positioned at an upper outlet in the shell (1), of an air inlet (2); baffle plates (4) are circumferentially fixed on inner walls of the shell (1) on the lower sides of the cyclone fins (3); and a guide pipe (6) is vertically fixed in the middle inside the shell (1). With the adoption of a manner of combining a cyclone type and a baffling type, condensate wateris separated for two times, so that separation is complete. Due to large-caliber air inflow, the flow velocity is reduced, and turbulence in the cavity is avoided. The flow velocity of gases in the cavity is low, and moisture is taken away by blocking airflow. Vibration caused by gas pulsation is reduced, damage to the cylinder and piston by liquid impact is avoided, wear of the cylinder and sealing element is reduced, the separation effect is excellent, the requirement on HG / T20570.8 Design of Gas-liquid Separator is met, and normal operations of compressor sets can be ensured. The service performance and service life of the compressor even the whole system are improved.

Description

technical field [0001] The invention relates to the structural improvement technology of the auxiliary device for gas-liquid separation of gas compressor equipment, and belongs to the technical field of B01D50 / 00 combined equipment for separating particles from gas or vapor in the IPC classification, especially the gas compressor combined cyclone baffle Large diameter gas-liquid re-separation device. 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 structures used in gas-liquid separators, and the separatio...

AI Technical Summary

Problems solved by technology

[0006] Generally, the separator adopts a single separation method, which may easily cause incomplete separation.

The flow rate at the inlet is high, which can easily cause turbulent flow after the gas enters the separator

Moreover, the size of the cylinder structure is not enough, and in areas with high humidity in the south, there will be a situation where it is too late to separate

When the moisture content is high and the gas flow rate is high, the ordinary guard plate cannot prevent the separated condensed water from splashing well, and even flows back with the gas
