Description

Sampling system for low-concentration discontinuous organized emission source

Technical Field

The utility model relates to a sampling system especially relates to a sampling system that is used for the discontinuous organic emission source of low concentration.

Background

With the development of society, people pay more and more attention to the prevention and treatment of air pollution, in order to improve the cognition of pollution sources, people classify various pollution sources, the classification methods are different, one class is classified into organized emission sources and unorganized emission sources, and in order to accurately master the data of the components, the content and the like of the pollution sources, the sampling is needed to be carried out for laboratory analysis.

The sampling process of the pollution source has a vital influence on the accuracy of laboratory result analysis, and for the organized emission source, especially for the sampling of the organized discontinuous emission pollution source, the existing sampling mode mainly comprises the steps of placing a sampler at the periphery of the pollution source or punching and sampling at the emission end, and the sampling mode has the defects of large influence of the peripheral environment, sampling omission caused by discontinuous emission, damage to the structure of the emission end, even no punching condition and the like, and can cause larger analysis result errors.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sampling system that is used for the discontinuous organized emission source of low concentration to the above-mentioned problem that exists in the pollution source sampling of discontinuous emission, solves among the current discontinuous organized emission source sampling method that receives all ring edge borders influence great, and the sampling is omitted, is destroyed emission end structure scheduling problem to realize stable, not influenced by all ring edge borders, sampling that can be long-time.

In order to achieve the above object, the utility model provides a sampling system for low concentration discontinuous organized emission source, sampling system includes reducing pipe, hose coupling pipe, three-way pipe, the fan that links to each other in proper order with the discharge port, two ports of three-way pipe pass through the connecting pipe respectively with hose coupling pipe, fan intercommunication, another port and the sample thief of three-way pipe are linked together, the downside of connecting pipe and fan is equipped with the support.

Preferably, all the connection ends are subjected to a sealing process.

Preferably, the fan is a waterproof fan.

Preferably, the reducer pipe, the flexible connecting pipe, the three-way pipe and the connecting pipe are all made of PVC materials, and the support is made of aluminum profiles.

Based on the technical scheme, the utility model has the advantages that:

the sampling system for the low-concentration discontinuous organized emission source of the utility model provides stable and continuous airflow power through the draught fan, and ensures the stability of the sampled airflow; the external environment is completely isolated from the sampling environment through sealing connection, so that the influence of the external environment on the sampling environment is avoided; the whole sampling device is supported to a proper height through the device bracket, and a foundation capable of sampling for a long time is provided. The utility model discloses a sampling system for low concentration discontinuous has tissue emission source has accuracy, stable, receives the advantage that all ring edge borders influence is little, can sample for a long time.
