Gas compression and storage system and control method

Abstract

A gas compression and storage system comprises a gas supply module, a gas holder, a gas inlet pipeline, a compressor module, a gas outlet pipeline, a detection module and a compression control module; the compressor module comprises a gas inlet end, a gas outlet end and a plurality of compressors connected between the gas inlet end and the gas outlet end in parallel; and the gas supply module, the gas holder, the gas inlet pipeline and the gas inlet end are sequentially connected, and the gas outlet end is connected with the gas outlet pipeline. The compression control module can control the gas containing amount in the gas holder in real time according to the detection value of the detection module, so that the total power of the compressor module is adjusted by independently controlling all compressors in the compressor module, the total gas suction amount of the compressor module adapts to the gas output amount of the gas holder, the balance of the gas input amount and the gas output amount of the gas holder is guaranteed, and the risk that the compressor module works unstably due to the fact that the gas holder is too flat or the gas leakage risk is caused due to the fact that the gas containing capacity in the gas holder is too large is avoided.

Description

Technical field [0001] The present invention relates to the field of gas compression, particularly to a gas storage system and a control method for compression. Background technique [0002] There are many industrial processes involved in specialty gases such as methyl chloride is toxic, colorless gas flammable, can form explosive mixtures with air, it is mainly used for the production of organosilicon compounds, is also widely used as solvents, extracting agents as well as the production of pesticides, pharmaceuticals , spices. Some industrial processes also chloride byproduct, for example, one hundred enemy insects, chloral, amine and phosphorus production process. [0003] These harmful gases in the production process requires delivery washed with water, pickled and sent to the gas cabinets, and then compressed by the compressor after condensation, freezing, liquefaction stored in cylinders. Often as a buffer gas cabinet is provided on the conveying path, the height of the gas...

AI Technical Summary

Problems solved by technology

However, in the prior art, due to changes in gas generation speed, gas delivery speed, etc., it is difficult to ensure the stability of the gas volume on the delivery path, that is, it is difficult to ensure the safety of the gas cabinet.
