AI Technical Summary
Technical Problem
When existing air compressors compress process gases, residual exhaust gas inside the compressor mixes with the process gas, resulting in a decrease in the purity of the process gas and posing a safety hazard.
Method used
An internal exhaust process is adopted, in which nitrogen is introduced into the compressor to replace the waste gas, and nitrogen is introduced again to discharge the process gas after the process gas is compressed. The inertness and stability of nitrogen are used to improve the purity of the process gas and ensure safety.
Benefits of technology
It improves the purity of process gases, reduces safety risks, and facilitates equipment disassembly, inspection, and maintenance.

Abstract
The application provides a screw type process gas compressor and an internal exhaust process thereof, and the internal exhaust process mainly comprises the following steps: power-on before starting, opening a waste gas outlet, opening a nitrogen inlet, exhausting waste gas by nitrogen, closing the nitrogen inlet, opening a process gas inlet, detecting the gas concentration of the waste gas outlet, closing the waste gas outlet, opening an outlet, and closing before stopping, wherein the process gas is replaced by nitrogen before stopping, nitrogen is conveyed into the compressor before compressing the process gas, so that the waste gas in the compressor is exhausted, the purity of the process gas is increased by using the inertness and stability of nitrogen, the process gas in the compressor is exhausted by conveying nitrogen into the compressor after compressing the process gas, the safety of the operator during disassembly, maintenance and maintenance is facilitated, and the process gas explosion during disassembly is prevented.
