Multi-channel multi-component fixed source sampling analysis device

The utility model provides a multi-channel multi-component fixed source sampling analysis device. A sampling gun is connected with a particulate matter cutting head, the particulate matter cutting head is connected with an MPS (microprocessor system) dilution system, the MPS dilution system is connected with an air compressor, a pneumatic joint of the MPS dilution system is connected with air inlets of gas-distributing pipes, the tail end of each gas-distributing pipe is provided with a gas emptying opening with a one-way valve, an equivalent sampling opening is respectively arranged on each gas-distributing pipe body, and the equivalent sampling openings are connected with a gas concentration sensor, a VOCs (volatile organic compounds) sampling frame, a particulate matter online detector and a particulate matter double-layer film sampling device. The smoke is guided into a cutter arranged behind the particulate matter cutting head through the sampling gun, and enters the MPS dilution system through an MPS temperature-accompanied gas guide hose after the grain components except the target particulate matter are removed, the sampling or the online analysis is carried out on the plurality of equivalent sampling openings, and each sampling device or analysis device is respectively provided with a power system, so that the redundant dilution gas can be discharged into the air through the gas emptying openings.
