Description
Technical Field
The utility model relates to an atmosphere sampling field especially relates to a sampling box for atmosphere sampling equipment that can control sampling temperature.
Background
Atmospheric sampling is the process of collecting samples of pollutants or contaminated air in the atmosphere. There are two types of in-situ sampling methods: one is to make a large amount of air pass through a liquid absorbent or a solid adsorbent to enrich pollutants with low concentration in the atmosphere, such as an air extraction method and a filter membrane method. Another type is to collect the air containing the contaminants with containers (glass bottles, plastic bags, etc.). The former measures the average concentration of the pollutants in the atmosphere within the sampling time; the latter measured instantaneous concentrations or average concentrations over a short period of time. The sampling mode is determined according to the purpose of sampling and the field situation. The sample should be representative. The sampling efficiency is high, the operation is simple and convenient, and the subsequent analysis and measurement are convenient to obtain reliable basic data of atmospheric pollution. Samples of atmospheric pollutants or contaminated air are collected in order to obtain basic data on atmospheric pollution.
Atmospheric sampling is an important step of atmospheric environment monitoring, and has a great reliability relation to monitoring data. Methods for collecting atmospheric samples mainly include two types: one is to make a large amount of air pass through a liquid absorbent or a solid adsorbent to absorb or retain pollutants, and enrich the original pollutants with lower concentration in the atmosphere, such as an air extraction method and a filter membrane method. The result of measurements with this type of method is the average concentration of the contaminants in the atmosphere over the sampling time. Another type is to use containers (glass bottles, plastic bags, rubber bladders, syringes, etc.) to collect air containing contaminants. Such methods are applicable in the following cases: the concentration of pollutants in the atmosphere is high; or the sensitivity of the determination method is higher; contaminated gases and vapors that are not readily absorbed by liquid absorbents or solid adsorbents. The result of this measurement is the instantaneous concentration or the average concentration in a short time of the pollutants in the atmosphere. In addition, there are cryogenic freezing methods that can be used to collect volatile gases and vapors, such as lead alkyls. The liquid absorbent in the sampler is mainly used for absorbing gaseous and vapor substances. Commonly used absorbents are: water, aqueous compound solutions, organic solvents, and the like. The absorbent must be capable of reacting with the contaminant rapidly or dissolving the contaminant rapidly and facilitating the analytical procedure. Hydrogen fluoride and hydrogen chloride in the air can be used as absorbent; the sulfur dioxide can be sodium tetrachloromercuric oxide as an absorbent; organophosphorus pesticides such as phorate (3911) and systematic phosphorus (1059) can be absorbed by 5% methanol. The solid adsorbent includes granular adsorbent and fibrous adsorbent. The commonly used granular adsorbents include silica gel, ceramic and the like, and are used for sampling gaseous state, steam state and particulate matters. The fibrous adsorbent comprises filter paper, a filter membrane, absorbent cotton, glass wool and the like, and the adsorption effect is mainly physical retention and is used for collecting particulate matters. Sometimes, the adsorbent is first impregnated with a chemical reagent to cause the pollutant to chemically react with the adsorbent to be adsorbed, and the adsorbent is mainly used for collecting gaseous or vapor pollutants.
The atmospheric sampling method is to select a proper sampling mode according to the purpose and the field situation of sampling. Such as continuous or instantaneous sampling, fixed-point sampling or flow sampling on the ground, air sampling by balloons and airplanes, environmental sampling, indoor sampling, pollution source sampling and the like. The sampling purpose and the sampling mode are different, and the sampling method and the sampler are also different. For example, the sampling of the particles in the chimney can be realized by selecting a proper position to punch according to the shape and height of the chimney, extending the collector of the sampler into the hole and performing air extraction and collection at the same power speed. This method is called isokinetic sampling.
The samples collected for atmospheric sampling should be representative. The sampling efficiency is high, the operation is simple and convenient, and the subsequent chemical analysis and measurement are convenient. Representative factors affecting the sample are the efficiency of the sampler and the absorbent, the location of the sampling point and the interference of the sampler with the air flow.
In recent years, an atmospheric sampling technique has been combined with an analytical test technique to constitute a device capable of continuously and automatically sampling, analyzing, measuring, and recording the measured results. Such devices can be monitored directly on site and are known as monitoring analyzers.
The atmosphere sampler plays a good role in detecting harmful gases in air and environment. With the continuous progress of science and technology, the air sampler also continuously pushes out new products, such as: products such as intelligent atmosphere sample thief, explosion-proof atmosphere sample thief, two gas circuits atmosphere sample thief, greatly enriched the classification of atmosphere sample thief.
In the field of atmospheric sampling, in different regions, the temperature difference of the regions may be relatively large, for example, in a cold climate in the winter in the north or in a hot climate in the summer in the south, the sampling device is affected by low temperature or high temperature, which is not favorable for the absorption liquid in the absorption bottle to optimally absorb the collected gas, and directly results in the accuracy of the subsequent chemical analysis. Simultaneously, in the automatic sampling process of unmanned on duty many positions timesharing, the absorption liquid in the absorption bottle that needs the save that has sampled, if be in high temperature, can make absorbed target chemical substance, wherein have some in the environment of volatilizing again with comparatively fast speed, also lead to influencing the accuracy of follow-up chemical analysis result, consequently, need control the absorption effect of absorption liquid in the absorption bottle, just can control the absorption effect of absorption liquid effectively.
