Gas-liquid mixed recovery type redundant material flushing device and gas-liquid mixed recovery type redundant material flushing method

Abstract

The invention relates to a gas-liquid mixed recovery type redundancy flushing device and method.The gas-liquid mixed recovery type redundancy flushing device comprises a first liquid storage tank, a second liquid storage tank, a gas storage tank, a four-way valve, a first gas branch and a second gas branch; the gas storage tank is connected with a first gas inlet in the top of the first liquid storage tank and a second gas inlet in the top of the second liquid storage tank through gas pipelines. A first liquid outlet and a first liquid inlet of the first liquid storage tank are connected with a second liquid outlet and a second liquid inlet of the second liquid storage tank through a flushing pipeline, a four-way valve is mounted on the flushing pipeline, two valve ports of the four-way valve are connected with the flushing pipeline, the other two valve ports of the four-way valve are connected with a product pipeline, and a product to be flushed is arranged on the product pipeline; two ends of the first gas branch are respectively connected with the gas pipeline and the flushing pipeline at the upstream of the four-way valve, and two ends of the second gas branch are respectively connected with the gas pipeline and the flushing pipeline at the downstream of the four-way valve. The flushing device can achieve a better flushing effect.

Description

technical field [0001] The invention relates to the technical field of aerospace, in particular to thermal equipment and fluid equipment, and in particular, to a gas-liquid mixed recovery type surplus flushing device and method. Background technique [0002] At present, in the fields of aerospace, weapons, thermal engineering and other technical fields, liquid systems composed of liquid working substances such as deionized water, ethylene glycol, and perfluorotriethylamine are often used. The liquid system often integrates complex flow channel structures such as cold plates, heat exchangers, elbows, and tees. In the production and assembly process, some metal processing debris, non-metal debris and other excess materials may be introduced. Long-term operation will cause pipeline blockage, flow reduction, and even flow interruption. In addition, the existence of excess material may also damage the quick-disconnector, filter, pump and other components, causing non-serious dam...

AI Technical Summary

Problems solved by technology

In the process of production and assembly, some metal processing debris, non-metallic debris and other redundant materials may be introduced. Long-term operation will cause pipeline blockage, flow reduction, and even flow failure.

In addition, the existence of excess may damage quick disconnects, filters, pumps and other components, causing serious damage to the system

At present, in the above-mentioned fields, the method of blowing off with high-pressure gas is generally used, but limited by the low density and momentum of the gas, the excess material brought out is actually limited, and a large part of it still exists.

Traditional liquid washing stations are often driven by pumps, which are large in size and occupy a large area, and are extremely inconvenient to use. Therefore, more efficient and convenient waste washing devices are needed
