Vortex refrigeration drain valve

Abstract

The invention discloses a vortex refrigeration drain valve, and belongs to the technical field of gas-liquid separation equipment. The vortex refrigeration drain valve comprises an outer cylinder, and is characterized by further comprising a refrigeration stainless steel cylinder, a stainless steel corrugated pipe is arranged in the refrigeration stainless steel cylinder, the upper part of the refrigeration stainless steel cylinder is connected with a stainless steel throttling hole inlet pipe, and the lower part of the refrigeration stainless steel cylinder is connected with a first needle valve; the upper end of the stainless steel corrugated pipe is connected with a vortex refrigerator and a second needle valve, a stainless steel floating cylinder is arranged in the outer cylinder, an upper positioning needle support is embedded in the top of the outer cylinder, an organic silica gel sealing head is embedded in the bottom of the outer cylinder, a capillary trap is arranged between the outer cylinder and the stainless steel floating cylinder, and the capillary trap is connected with a sample gas outlet pipe; and the upper end of the sample gas outlet pipe is connected with a third needle valve. According to the invention, the refrigeration temperature of the sample gas under pressure can be adjusted, gas-liquid separation can be reliably and thoroughly carried out, automatic gas-liquid separation without external force and lever is realized, and the separation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation equipment, in particular to a vortex refrigeration liquid discharge valve. Background technique [0002] The gas-liquid separator can be installed at the inlet and outlet of the gas compressor for gas-liquid separation. It can be used for gas phase demisting of various gas washing towers, absorption towers and desorption towers. The gas-liquid separator can also be used in various industrial and civil occasions such as gas dust removal, oil-water separation and liquid removal of impurities. [0003] The commonly used separation method of gas-liquid separator is gravity sedimentation method. Due to the difference in specific gravity between gas and liquid, when the liquid flows together with the gas, the liquid will be subjected to a greater force of gravity, resulting in a downward velocity, while the gas still flows in the original direction, that is, the liquid and the gas are in...

AI Technical Summary

Problems solved by technology

However, the refrigeration temperature of the sample gas under pressure cannot be adjusted, and the automatic separation of gas and liquid cannot be realized reliably and completely; because it is manually adjusted, it cannot realize automatic separation of gas and liquid without external force and lever, and the separation efficiency is poor
