Problems solved by technology

[0004] 2. Online gas detectors are all point sampling analysis, which cannot realize mixed sampling in a wide range of spaces
From the above two points, it can be seen that the current sampling method of gas detectors is very simplistic, and there will be many inconveniences in gas sampling and analysis in actual work

Embodiment 1

[0030] On the basis of the above structure, in this embodiment, a filter 6 is installed on the air inlet pipe 4 and / or on the air outlet pipe 3, and the filter 6 on the air inlet pipe 4 is located between the air pump and a plurality of branch pipes, and the filter 6 Located on the intake pipe 4 between the air pump 2 and the branch pipe closest to the air pump 2 . During detection, the moisture and dust in the sample gas taken are filtered out through the filter 6, so as to prevent the moisture and dust in the sample gas from entering the gas pump 2 and gas detector 1 and affecting their working performance, ensuring that the gas pump 2 and gas detector 1 work performance.

[0031] The above-mentioned filter 6 adopts the prior art, such as an activated carbon filter, and its specific structure and principle will not be repeated here.

[0032] Preferably, the number of the above-mentioned filter 6 can be one. At this time, the filter 6 can be installed on the inlet pipe 4, or...

Embodiment 2

[0036] On the basis of Embodiment 1, in this embodiment, both ends of the air intake pipe 4 are open, one end communicates with the air inlet of the air pump 2, the other end communicates with one end of one of the branch pipes, and one end of the remaining branch pipes communicates with the air inlet of the air pump 2. The parts between the two ends of the intake pipe 4 are connected, the structure is simple, the design is reasonable, and the sampling is convenient and fast.

Embodiment 3

[0038] On the basis of Embodiment 1, in this embodiment, one end of the intake pipe 4 is open and the other end is closed, and its open end communicates with the air inlet of the air pump 2. The parts between them are connected, the structure is simple, the design is reasonable, and it is convenient and fast to take samples.

Abstract

The invention relates to on-line gas multipoint sampling detection equipment which comprises a gas detector, a gas pump and a plurality of detection heads, wherein a gas outlet of the gas pump is communicated with the gas detector through a gas outlet pipe, and a gas inlet of the gas pump is communicated with a gas inlet pipe; the plurality of detection heads are respectively communicated with thegas inlet pipe through branch pipes, and each branch pipe is provided with a valve. The equipment has the beneficial effects that multi-point successive sampling or multi-point mixed sampling can berealized, the sampling is convenient, the sampling efficiency is greatly improved, and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of gas detection equipment, in particular to a multi-point sampling and detection equipment for online gas. Background technique [0002] At present, the sampling methods of online gas detectors on the market are divided into two types: pump suction sampling and diffusion sampling analysis. The detection range is within a radius of three meters from the sampling point. Online gas detector sampling has the following defects: [0003] 1. Online gas detectors can only achieve single-point sampling. If it is necessary to analyze the gas samples in multiple adjacent areas or in different adjacent pipeline containers without distinguishing between areas, you can only install gas detectors in different areas or move the sampling tubes of the gas detectors to different areas in sequence . [0004] 2. Online gas detectors are all point sampling analysis, which cannot realize mixed sampling in a wide range of space...
