Problems solved by technology

[0003] Existing gas samplers usually need to carry out vacuum treatment on the sampling bottle, or use an aspirator to directly sample the sample gas. The disadvantages are: on the one hand, the vacuum treatment procedure of the sampling bottle is complicated and the operation is cumbersome, and the gas container used for sampling is subject to On the other hand, using the air pump to directly sample the sample gas, the sample gas needs to pass through the pipeline and the air pump, which is not only easy to cause pollution to the sample gas and affect the measurement, but also the sampling of corrosive gases will also affect the air pump and its Pipelines have higher requirements

Abstract

The invention discloses a cabin type gas sampler, comprising a sampling device and a control system, wherein, the control system is connected with the sampling device and is provided with an air pump and a controller; the controller is electrically connected with the air pump and controls the air pump to operate by outputting control signals; the air pump is communicated with the sampling device by a pipeline. The gas sampler is characterized in that the sampling device comprises a sealed cabin and a sample storage device which is arranged in the sealed cabin and is communicated with the outside of the sealed cabin. The gas sampler has high reliability and simple structure and does not need to carry out vacuum treatment on sample gas collection containers, thus having simple operation procedures and wide application range.

Description

technical field [0001] The invention relates to a gas sampler, in particular to a cabin type gas sampler. It belongs to the field of environmental protection instruments. Background technique [0002] The gas sampler used by the environmental testing department is usually equipped with an air extraction system. The air extraction system includes an air extraction pump and its control circuit. The control circuit controls the air extraction pump to sample the sample gas, or uses a vacuum-treated sampling bottle for gas sampling. , for further analysis of the sample gas. CN2006201514111 discloses a gas sampler for vacuum sampling, which includes a sampler, a sampling barrel, and a sampling gun; the sampler includes a housing, an air pump, a four-way control valve, a motor, and a power supply; the housing is provided with a power gas interface; The barrel includes a barrel body and a sealed barrel cover. The barrel body is provided with a power gas interface and a sampling in...
