Description

Technical Field

[0001] The utility model relates to the technical field of gas sampling, in particular to a safe and environmentally friendly gas sampling device for petrochemical industry. Background Art

[0002] There are two types of gas sampling methods: one is to allow a large amount of air to pass through a liquid absorbent or solid adsorbent to enrich pollutants with lower concentrations in the atmosphere, such as the air extraction method and the filter membrane method; the other is to use a container to collect air containing pollutants. The former measures the average concentration of pollutants in the atmosphere during the sampling time; the latter measures the instantaneous concentration or the average concentration in a short period of time. The sampling efficiency should be high, the operation should be simple, and it should be easy to carry out subsequent analysis and measurement to obtain reliable basic data on gas pollution. Therefore, a safe and environmentally friendly gas sampling device for petrochemical enterprises has appeared on the market and is widely used.

[0003] There are currently safe and environmentally friendly gas sampling devices for petrochemical companies on the market. During sampling, it is inconvenient to support the sampling device, which results in the staff needing to hold the sampling tube steady while ensuring the horizontal position of the sampling tube, which can easily lead to poor sealing and reduce the efficiency of sampling.
