Sound field reinforced coalescence separation system

Abstract

The invention discloses a sound field reinforced coalescence separation system which comprises an oil remover, the upstream detection device is connected with an upstream pipeline of the degreaser and is used for detecting the quantity and the particle size of liquid drops carried by gas in the upstream pipeline; the upstream sound wave generation device is connected with the upstream detection device and is used for adjusting sound waves according to the number and the particle size of the liquid drops so as to coalesce the liquid drops in the upstream pipeline; and the pre-separator is connected with the inlet of the oil remover and is used for intercepting the coalesced liquid drops to realize gas-liquid separation. The sound field enhanced coalescence separation system can greatly reduce the liquid concentration of the gas entering the degreaser, and especially when the liquid content or the particle size range in the incoming flow gas of the upstream pipeline is obviously increased in the gas storage ground gas injection process, the liquid removal effect is more obvious. Therefore, the liquid drops carried in the gas can be efficiently separated, so that the requirement of gas-liquid separation can be met.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation, in particular to a sound field enhanced coalescence separation system. Background technique [0002] Gas storage is an artificial gas field or gas reservoir formed by reinjecting natural gas produced from a gas field or transported by long-distance pipelines into the underground space where gas can be stored. At present, reciprocating compressors are usually used in the gas injection process. The high-pressure natural gas discharged from the outlet of the compressor needs to pass through the degreaser to remove the lubricating oil droplets entrained in the gas, so as to prevent the lubricating oil from entering the ground and causing formation pollution. [0003] The coalescing filter element is the core component of the degreaser. The filter material of the coalescing filter element is a porous fiber medium. It will form millimeter-sized large droplets, and finally the large dropl...

Problems solved by technology

However, due to the high liquid concentration in the outlet gas of the reciprocating compressor and the wide range of droplet size distribution, the gas liquid content and droplet size exceed the processing range of the coalescing filter element, making it difficult to meet the requirements of efficient gas-liquid separation

[0004] Therefore, how to avoid the difficulty of meeting the requirements of high-efficiency gas-liquid separation through the coalescing filter element is a technical problem that those skilled in the art need to solve at present.
