Abstract
A filter system for a flue gas sampling gun relates to a filter system and solves the problems that a conventional flue gas sampling gun intakes flue gas directly, dust particles in the flue gas are adhered to the wall of a sampling gun barrel and an absorption bottle, thereby causing sampling channel blockage which influences analysis to flue gas components and the service life of the sampling gun. The filter system for the flue gas sampling gun comprises a filter cylinder and a protective screening, wherein one end of the filter cylinder is opened and the other end of the filter cylinder is sealed, the sealed end of the filter cylinder takes the shape of a warhead, the filter cylinder is a filter cylinder made of wood chip paper, the opened end of the filter cylinder is mounted at the flue gas entry end of the gun barrel, the protective screening and the filter cylinder are the same in shape, and the protective screening is sleeved with the filter cylinder. According to the invention, dust is effectively prevented from entering into the sampling gun, blockage and erosion of dust to the sampling gun can be avoided, and the service life of the sampling gun is prolonged greatly. The filter system provided by the invention is used for sampling and filtering the flue gas of a chimney flue at the outlet of a fuel electric plant denitration system.
Description
Technical field
The present invention relates to a kind of filtration system, be specifically related to a kind of thermal power plant denitrating system exhaust pass flue gas sampling rifle filtration system.
Background technology
For understanding the smoke components of thermal power plant denitrating system exhaust pass, so as to denitrfying agent being provided best proportioning and improving denitration efficiency (comprising the change of smoke components), all in denitration device performance test (performance test that comprises the examination of denitration device performance and scrap build front and back), sample to flue gas, and sample is carried out chemical analysis.Will use smoke components sampling rifle during sampling, sampling rifle gun barrel part is made by stainless steel tube, and its rifle head is inserted in the flue, by sampling pump flue gas is pumped in the absorption bottle.
Because the two ends of gun barrel are opened type, directly flue gas is sucked in the sampling system, contained dust in the flue gas (0.05～600 μ m) will be attached in sampling gun barrel wall, valve head and the absorption bottle, cause the sampling system blocked path, even each parts of erosion, both influenced the analysis of normal sampling smoke components, also the service life of influence sampling rifle.
Summary of the invention
The objective of the invention is directly to suck flue gas for solving existing flue gas sampling rifle, grit in the flue gas is attached in sampling gun barrel wall and the absorption bottle and causes the sampling blocked path, influence the analysis of smoke components and the rifle problem in service life of sampling, and then a kind of flue gas sampling rifle filtration system is provided.
The present invention addresses the above problem the technical scheme of taking to be: a kind of flue gas sampling rifle of the present invention comprises filter cylinder and protection network with filtration system, described filter cylinder is the filter cylinder of the uncovered and other end of end sealing, being shaped as of the blind end of filter cylinder is bullet-shaped, described filter cylinder is wood pulp cellulose papery filter cylinder, the opening end of filter cylinder is used for being installed in the smoke inlet end of gun barrel, the shape of protection network is identical with the shape of filter cylinder, and protection network is sleeved on the filter cylinder.
The invention has the beneficial effects as follows: one, filter cylinder effectively elimination sampling dust in flue gas (0.05～600 μ m), prevent that dust from entering in sampling rifle and the sampling system, the filter cylinder aperture is little, Air permenbility is big, low and the efficient height of resistance, and filter area is big, not only help to improve the accuracy of sampling fume component analysis, the degree of accuracy is compared existing 80% and has been brought up to more than 95%, and can prevent effectively that dust from entering the sampling rifle, avoid clogging and dust to the sampling rifle erosion, prolonged the service life of sampling rifle widely, the present invention can make compare existing service life (50～70 hours) to have improved 20%-40% in service life of sampling rifle; Protection network can be protected filter cylinder effectively, and filter cylinder is unlikely at the sampling rifle from being inserted into the damage of extracting out the overall process; Two, overall structure of the present invention is simple, and is reasonable in design, easy to install, and the filtering type flue gas sampling rifle that the present invention forms can well be applied in the flue gas sampling of thermal power plant denitrating system performance test.
