Multipurpose particulate matter sampler

Abstract

The invention discloses a multipurpose particulate matter sampler. The sampler comprises a host machine; a particulate matter sampling head is fixed at the upper part of the host machine; a gas flow aligner, a sampling servo mechanism, a power supply and an exhaust interface communicated with the outside atmosphere are arranged in the host machine; the top of the gas flow aligner is communicated with the bottom of the particulate matter sampling head; the bottom of the gas flow aligner is connected with the input end of the sampling servo mechanism; and the output end of the sampling servo mechanism is communicated with the exhaust interface. The sampler is a complex, has multiple purposes, is reliable and plastic in analysis data and high in sampling field working efficiency, and saves the construction and administrative cost.

Description

technical field [0001] The invention belongs to the technical field of sampling equipment, and in particular relates to a multipurpose particle sampler. Background technique [0002] Multi-purpose particle sampler, with the country's emphasis on the ecological environment, the country's adjustment of industrial policies, the application of nuclear energy and the continuous development of the nuclear industry, the problems of radioactive pollution prevention and control, monitoring and protection have also followed. Make the ecological environment level balance and stability. Strengthen the construction of nuclear and radioactive environmental detection capabilities, increase the local background monitoring of the ecological environment, especially in areas with polluted units and nuclear facilities and equipment areas, conduct fixed-point and non-fixed-point sampling of environmental particulate matter, and analyze nuclide types, concentrations, and gamma radiation Level an...

Problems solved by technology

[0003] Existing similar particle samplers only have single-purpose functions, such as: portable samplers, which can only be used as portable sampling equipment during design; all-weather and indoor assembled samplers can only be used at fixed points; Waterproof, not moisture-proof, not suitable for long-term use in the open air, fixed samplers are inconvenient and portable, the requirements for waterproof, moisture-proof, anti-condensation and shell materials of the control units of these three types of equipment are different, and the communication functions are different. Unstable, some samplers have neither communication function nor control function, there is only one working mode for sampling, the flow rate is unstable, the source cannot be molded, the data usage varies greatly, and one machine cannot be used for multiple purposes
