Problems solved by technology

Since the M-type adopts four rows and three stages, it will inevitably lead to low utilization rate of the kinematic mechanism, redundancy of the kinematic mechanism, cylinder, piston, cooler, and piping system. The whole equipment is complex, occupies a large area, and is difficult to maintain. The compressor Poor economical use

Abstract

The invention discloses a combined gas piston compressor, comprising an M-type compressor which consists of a first first-stage cylinder, a second first-stage cylinder, a second-stage cylinder and a third-stage cylinder; the first first-stage cylinder consists of two independent gas inlet chambers and a mixed gas exhausting chamber which are communicated with a compression chamber; the two gas inlet chambers are respectively communicated with a feed gas channel and a branch channel of recycle gas; the gas inlet chamber of the second first-stage cylinder is communicated with the other branch channel of the recycle gas; the mixed gas exhausting chamber is communicated with the gas exhausting chamber of the second first-stage cylinder and the gas inlet chamber of the second-stage cylinder; the gas exhausting chamber of the second-stage cylinder is communicated with the gas inlet chamber of the third-stage cylinder; and the gas exhausting chamber of the third-stage cylinder is communicated with a lead-out pipeline. Preceding stage pressurization, mixing and compression are carried out on feed gas and the recycle gas with different initial pressures by the specially designed first first-stage cylinder to meet the requirements. The combined gas piston compressor has the advantages of simple structure, high integration, high mechanical efficiency, small occupied area, easy maintenance and the like.

Description

technical field [0001] The invention relates to a combined gas piston compressor, which is especially suitable for the combined gas piston compressor of raw material gas and circulating gas in the process of liquefied natural gas. Background technique [0002] Piston compressor is a kind of dynamic equipment to increase gas pressure, and multi-stage and multi-column compressors are the development direction of modern manufacturing industry. The compression of feed gas and recycle gas in the existing liquefied natural gas process generally uses two independent compressors, the feed gas adopts two-stage compression, and the recycle gas adopts three-stage compression. The two-stage raw gas compressor adopts 2D compressor motion mechanism, equipped with a primary cylinder and a secondary cylinder, with a symmetrical layout. The equipment is equipped with a common base on which the motion mechanism, cylinder, piston, air valve, oil pump station, and gas cooler are placed. , moto...
