Gas sampling, preventing and extinguishing cleaning unit for multifunctional tube bundle monitoring emergency preventing and extinguishing system

Abstract

The invention relates to a gas sampling, preventing and extinguishing cleaning unit for a multifunctional tube bundle monitoring emergency preventing and extinguishing system. The cleaning unit can carry out emergency fire extinguishing while carrying out sampling inspection and has good instantaneity and strong harmony. The technical scheme is as follows: the cleaning unit comprises a gas extracting device, a cleaning device and a nitrogen input device and is characterized in that the gas extracting device comprises vacuum pumps; the vacuum pumps are respectively connected with extraction valves and exhaust valves; the extraction valves are connected with a sampling extraction main pipe; the exhaust valves are connected with an exhaust emission main pipe; the cleaning device comprises anoil-free air compressor; the input end of the oil-free air compressor is connected with an air filter and the output end thereof is connected with a gas-filled heat exchanger and a cleaning gas-filled main pipe respectively by a switching solenoid; and the cleaning gas-filled main pipe is connected with a cleaning solenoid.

Description

technical field [0001] The invention relates to the technical field of mine monitoring, in particular to a gas sampling anti-extinguishing cleaning unit of a multifunctional tube bundle monitoring emergency anti-extinguishing system. Background technique [0002] At present, mine gas detection has been popularized and applied in coal mines. Mine hazard monitoring adopts video monitoring, temperature remote sensing, gas monitoring and other methods; among them, 1. Temperature remote sensing adopts on-site power supply sensor monitoring and transporting to the ground; 2. Video monitoring uses on-site power supply camera monitoring to play a preventive role; 3. Gas monitoring There are two methods: on-site sensor monitoring signals are sent to the ground, and downhole gas negative pressure is extracted to the ground through the tube bundle pipeline for testing; the sampling analysis of the tube bundle monitoring system mainly includes gas chromatography analyzers, infrared gas ...
