Abstract
The utility model discloses a uniform gas distribution structure of air inlet of flue gas filter, an air inlet pipe accesses from the bottom of the filter and is arranged at the center of the filter, a ceramic tube placing zone is provided with multi-group of ceramic tubes, which are uniformly distributed around the air inlet pipe, the top of the guard ring is fixed at the center of the top part of the filter by a guard board, and the peripheral of the guard ring is arranged with several pieces of flow deflectors, and the lower end of the flow deflector is spaced at the peripheral of the air inlet pipe. The utility model carries out deceleration and guiding of air-flow by installation of many pieces of flow deflectors, thereby preventing washing of local ceramic tube, effectively minimizing deposition amount of dust on the local ceramic tube, and improving service life of the ceramic tube; the top of the air inlet pipe is effectively spaced for preventing noise generated by shock during work. According to real operation comparison, the service life of the ceramic filter tube can increase about five months, thereby substantially shortening maintenance time of equipment and improving reliability of equipment.
Description
Technical field
The utility model relates to the flue gas purifying equipment field, especially the even gas distribution structure of the air inlet of smoke filter.
Background technology
" rich coal, oil starvation, weak breath " is the energy resources present situation of China; Develop novel Coal Chemical Industry; Particularly, make full use of the coal development Coal Chemical Industry and the novel gas generation technology of China's abundant, help the comprehensive utilization and the alternative oil of resource along with the development of China's Coal Gasification Technology; Meet the present industrial policy of China, and the purification techniques of coal gas seems particularly important in whole process flow.Smoke filter is the key equipment in combustion gas-Steam Combined Cycle technology; The ceramic membrane filter tube that 300～500 ℃ high temperature and high pressure gas gets into this equipment filters; The fine solid particle particulate is isolated in the filter membrane surface on earthenware surface, and clean high-temperature gas is then separated out and is collected through the earthenware tube wall.In a whole set of cleaning system, the gas flow rate of high temperature and high pressure gas porch reaches 7～9m/s, and present air inlet pipe gas distribution is relatively simple for structure; Air inlet pipe stretches into filter central authorities, organizes earthenware more and is distributed on the air inlet pipe periphery, after gas pours filter from bottom to top from air inlet pipe; Direct impact filter top also is dispersed to earthenware all around; What this gas circuit made that the earthenware near the air inlet pipe exit receives gas washes away comparison severity, and the long-term back of using is prone to wear and tear, and gas concentrates on the filtration of specific place easily; Make the filtration of whole group earthenware very inhomogeneous, also can shorten the service life of earthenware.The air inlet pipe top is a free end, does not have spacing constraint, during work vibrations bigger, noise is very big and damage easily.
The utility model content
The applicant is relatively simple for structure to the air inlet pipe gas distribution of above-mentioned existing smoke filter; Be easy to generate the earthenware wearing and tearing and filter shortcomings such as inhomogeneous; A kind of even gas distribution structure of air inlet of smoke filter rational in infrastructure is provided; Thereby can effectively realize even gas distribution, guarantee filter quality and prolong service life of earthenware.
The technical scheme that the utility model adopted is following:
The even gas distribution structure of a kind of air inlet of smoke filter; Air inlet pipe inserts and is arranged on the central authorities of filter from filter bottom; Earthenware is laid the district and is provided with many group earthenwares, is distributed on the periphery of air inlet pipe, and the top of guard ring is fixed on the center of top of filter through backplate; The periphery of guard ring is provided with some deflectors, the spacing periphery in air inlet pipe in the lower end of deflector.
It is further characterized in that: said deflector is provided with more than three or three.
The lower end of said deflector is fixed on the periphery of air inlet pipe through connecting plate.
The beneficial effect of the utility model is following:
The utility model slows down and guiding to air-flow through the multi-disc deflector is installed, and prevents the washing away of local earthenware effectively reduced the deposition of dust on local earthenware, improves the service life of earthenware; The top of air inlet pipe is also spacing by effectively, and vibrations produce noise when preventing work.According to actual motion relatively, can increase the service life of ceramic filter tube about 5 months, shorten the maintaining time of equipment greatly, improve the reliability of equipment.
Description of drawings
Fig. 1 is the front view of the utility model, broken section.
Fig. 2 is the cutaway view in A-A cross section among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1; The air inlet pipe 1 of the smoke filter of the utility model inserts and is arranged on the central authorities of filter 7 from filter 7 bottoms; Earthenware is laid district 6 and is provided with many group earthenwares; Be distributed on the periphery of air inlet pipe 1, be provided with the even gas distribution structure of the described air inlet of the utility model, at least three deflectors of periphery setting 3 of guard ring 4 in the center of top of filter 7; The top of guard ring 4 is fixed on the top of filter 7 through backplate 5, and the lower end of deflector 3 is fixed on the periphery of air inlet pipe 1 through connecting plate 2.
During real work; The gas of HTHP pours filter 7 from bottom to top through air inlet pipe 1; Down turn back to guard ring 4 most of gas up is flushed to backplate 5 under action of inertia after, consumed portion of energy this moment, and gas flow rate decreases; Gas after turning back looses to exterior portions through the guiding of deflector 3, and more slow entering earthenware is laid district 6.According to earthenware group number what, multi-disc deflector 3 can be installed between guard ring 4 and air inlet pipe 1, air-flow can evenly be flowed to different directions as requested; Through such design; Air-flow is slowed down, prevent the washing away of local earthenware, and can obtain to plan the air-flow of the flow direction; Effectively reduce the deposition of dust on local earthenware, the service life of improving earthenware; The top of air inlet pipe 1 is also spacing by effectively, and vibrations produce noise when preventing work.According to actual motion relatively, used the smoke filter of the utility model, compared with prior art: can increase the service life of ceramic filter tube about 5 months, shorten the maintaining time of equipment greatly.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
