Abstract
The utility model provides a gas on-line analyzer sampling head filter, which comprises a filter body and a filtration part arranged in the filter body. The filter body consists of an adsorption trap enclosure, and adsorption trap covers connected with both ends of the adsorption trap enclosure. The filtration part consists of an absorption core arranged in an inner chamber of the adsorption trap enclosure, and a dust filtration plate arranged on one end of the inner chamber of the adsorption trap. The adsorption trap covers and the dust filtration plate are communicated with the inner chamber of the adsorption trap enclosure. The utility model has simple structure; can remove interference components, such as dust and water, from flue gas effectively; and improve accuracy of measurement result. In particular, the utility model can significantly improve the accuracy of quantity measurement of chlorine hydride, prevent instruments from being eroded, improve service life of instruments, and is exclusively used on a sampling head of a gas analyzer.
Description
Technical field
The utility model relates to a kind of filtration unit, particularly relates to a kind of gas on-line analyzer sampling head filtrator.
Background technology
Cause people's injures and deaths in the fire and mainly contain two kinds of factors, first burn, it two is to suck smoke poisoning.The composition of flue gas is very complicated, also comprises carbon monoxide, carbon dioxide, hydrogen cyanide, hydrogen chloride, nitrogen monoxide, acryl aldehyde, hydrogen bromide, hydrogen fluoride, benzene and homolog thereof outside the smoke abatement, and water vapor etc.At present, the main employing carried out the analysis of smoke components based on the gas on-line analyzer of fourier infrared converter technique.In the flue gas analysis process, on the one hand owing to contain flue dust in the flue gas, often cause sampling head to stop up, in addition the aspect since the hydrogen chloride gas in the flue gas easily by water vapor adsorption, cause the hydrogen chloride detected level to reduce, thereby cause testing result inaccurate, the water vapor that adsorbs simultaneously behind the hydrogen chloride can corrode instrument, shortens the serviceable life of instrument.
Goal of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, easy to use, can effectively remove dried gas on-line analyzer sampling head filtrator of scratching composition in the gas analysis.
The utility model gas on-line analyzer sampling head filtrator comprises filter body and is arranged on the interior filtration members of filter body.Wherein, filter body is made up of adsorption trap housing, the absorption area grating that is connected with adsorption trap housing two ends; Filtration members is by the absorbent core that is arranged on adsorption trap housing inner chamber, and the dust-filtering plate composition that is arranged on adsorption trap housing inner chamber one end, and absorption area grating and filter all communicate with adsorption trap housing inner chamber.Wherein, easy to use for processing, the absorption area grating can adopt with the adsorption trap housing and be threaded, and its other end also has screw thread, is convenient to connect sampling head.
The principle of work of the utility model gas on-line analyzer sampling head filtrator is, during use, the absorption area grating of one end is connected with sampling head, another termination gas cell, gas to be measured in the gas cell enters adsorption trap housing inner chamber by the absorption area grating, after absorbent core and dust-filtering plate are removed moisture and flue dust, enter the analyser sampling head from another absorption area grating again.
The advantage of the utility model gas on-line analyzer sampling head filtrator is simple in structure, not only moisture be can remove, flue dust, good filtration effect removed simultaneously, the gas that enters in the sampling head with assurance does not contain interfering material, thereby makes the gas analyzer analysis result more accurate.Be exclusively used on the sampling head of gas analyzer.
