AI Technical Summary

Technical Problem

Existing gas and dust explosion pipeline testing equipment is prone to causing compressor pipe blockage and powder entering the pump to wear down the machine when discharging explosion products. Furthermore, improper methods of toxic gas discharge can endanger operators.

Method used

An improved gas and dust explosion pipeline test device was designed. It adopts a combination of a closed control valve, a gas intake control valve, a dust collector, an airbag, a vacuum control valve, and a vacuum pump to achieve non-contact collection of gas and powder. Through the cooperation of the gas supply component, ignition controller, explosion cover, ignition electrode, explosion tube, dust spray component, and data acquisition and control component, the safety and convenience of experimental operation are ensured.

Benefits of technology

It enables automated, contactless collection of gases and powders, avoiding equipment blockage and operator hazards, and broadens the scope of experimental research.
