Abstract

The invention discloses a gas pretreatment pressurizing device, and relates to the correlative technical field of gas pretreatment. The gas pretreatment pressurizing device comprises a device body. Agas inlet cavity and a gas outlet cavity are formed in the two sides of an inner cavity of the device body. A first installation groove is formed in the lower end of the middle of the device body, anda second installation groove is formed in the upper end of the middle of the device body. The invention further discloses a control method of the gas pretreatment pressurizing device. The control method comprises eight steps. Stable operation of a plurality of parallel roots blowers can be effectively guaranteed, and the effects of economical operation and stable operation are achieved. Accordingto the gas pretreatment pressurizing device, the first installation groove and the second installation groove are formed in the device body, a variable-frequency motor is fixedly installed in the first installation groove, the roots blowers are fixedly installed in the second installation groove, and therefore the variable-frequency motor and the roots blowers can be conveniently installed and replaced, and the working efficiency of the pressurizing device is improved.

Description

technical field [0001] The invention relates to the related technical field of gas pretreatment, in particular to a gas pretreatment booster device and a control method thereof. Background technique [0002] Gas is a kind of unconventional natural gas stored in coal seams. It is a harmful gas that is emitted automatically during coal mining. The main component is methane, which is colorless, odorless, flammable and explosive. When the concentration in the air reaches 5% to 16%, it will explode in case of an open flame, and it is a "safety killer" in coal mines. But at the same time, gas is also a kind of clean energy with high utilization value. Using gas to generate electricity is an economical and beneficial way. [0003] Limited by domestic coal mine gas extraction conditions, the concentration of gas extracted from coal mines is generally low. In the comprehensive utilization of gas, a methane concentration above 25% can be considered as high-concentration gas. At pres...
