Description
Technical Field
The utility model relates to an atmosphere sampling equipment field especially relates to a prevent animal invasion atmosphere sampling device that prevents animal such as mosquito invasion, interference sampling, damage equipment.
Background
Atmospheric sampling is an important step of atmospheric environment monitoring, and has a great reliability relation to monitoring data. The method for collecting the atmospheric sample mainly comprises two types, one is that a large amount of air passes through a liquid absorbent or a solid absorbent to absorb or retain pollutants, and the original pollutants with lower concentration in the atmosphere are enriched, 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.
Outdoor sampling is interfered by mosquitoes and other small animals, sampling is interrupted if the outdoor sampling is not performed normally, a sampler is damaged seriously, and unexpected loss is caused.
Therefore, an anti-animal invasion atmosphere sampling device for preventing mosquito invasion, interference sampling and damage of equipment is needed.
