Description
Technical field
The utility model relates to a kind of dust arrester, particularly relates to a kind of high-temperature flue gas pretreatment dust arrester.
Background technology
Along with developing rapidly of economy, be that the boiler of fuel increases a lot with raw coal, the atmosphere pollution of these stoves discharge causes very large harm to surrounding environment, and therefore dedusting technology also must develop thereupon.Existing dedusting technology can be divided into mechanical dust collector, electric cleaner, scrubber and filter collector etc. by trapping mechanism.Wherein, mechanical dust collector efficiency of dust collection is low, and electric cleaner investment is high, floor space is comparatively large, and scrubber running expense is high, and what therefore the application of dedusting was at present maximum is filter collector.Filter collector makes dust-contained airflow by filtrate by grit separation and collection, and efficiency of dust collection is generally 90% ~ 99%, but is not suitable for the high dusty gas of temperature.In filter collector, the most frequently used is sack cleaner, in order to avoid high temperature failure filter bag, for high-temperature flue gas, needs first to carry out pre-dedusting before carrying out bag-type dusting.Pre-dedusting adopts cyclone dust collectors under normal circumstances, but dust removal efficiency in cyclone cleaner is low, and does not have obvious cooling effect, and during flue gas arrival sack cleaner, temperature is still very high, still can cause very large infringement to filter bag.
Summary of the invention
The utility model is for solving the problems of the technologies described above and providing a kind of high-temperature flue gas pretreatment dust arrester.
Technical solution adopted in the utility model is: a kind of high-temperature flue gas pretreatment dust arrester, comprises outer cylinder body and inner barrel; In the middle part of described outer cylinder body, upper position is provided with Turbogrid plates, is provided with ash bucket below Turbogrid plates; Described outer cylinder body sidewall is provided with air inlet near top, exports correspondence position be provided with opening for deashing near bottom and described ash bucket; Described inner barrel and described outer cylinder body are coaxially arranged, and bottom is connected on described Turbogrid plates by support, and top is stretched out from described outer cylinder body upper surface and be provided with gas outlet on extension sidewall; The filter of band filter bores is connected with in described inner barrel; Described inner barrel and described filter are hollow structure, and cavity is connected; Described cavity top is provided with water filling port, and sidewall is provided with delivery port.Cold water Automatic water-filling mouth injects, and completes after heat exchange and flows out from delivery port, then through pond, water pump is circulated to water filling port, both saving water resources, realize flue gas cool-down again.Whole dust arrester integrated design, outer cylinder body is directly placed in plane, and structure is more firm.After flue gas enters outer cylinder body, first hit on the outer wall of the inner barrel filling cooling water in cavity, tentatively lower the temperature and rough dusting; Flue gas declines along cooling water cavity outer wall afterwards, and temperature progressively reduces; Flue gas drops to below inner barrel, enters inner barrel, lowers the temperature further, further cools and dust removal by filtration at the filter place filling cooling water.
In order to strengthen cooling effect and efficiency of dust collection further, described filter has polylith, arranged in parallel.
In order to further strengthen cooling effect and efficiency of dust collection, the filter bores of adjacent described filter staggers mutually, to increase flue gas and filter collision rate.
In order to further improve efficiency of dust collection, in described outer cylinder body, be provided with the circular filter net be stuck in outside described inner barrel.
As preferably, described inner barrel is rounding taper type.After flue gas enters outer cylinder body, speed slows down; Along with flue gas is descending, inner barrel sectional area is more and more less, and between inner barrel and outer cylinder body, partial cross section amasss increasing, and therefore velocity of flue gas is more and more slower; After flue gas enters inner barrel, along with flue gas is up, inner barrel cross-sectional area is increasing, and velocity of flue gas is again more and more slower, contributes to the carrying out of flue gas ash removal, improves flue gas dedust efficiency.
The advantage that the utility model has and good effect are: because the utility model adopts as above technical scheme, after flue gas enters outer cylinder body, first hit on the outer wall of the inner barrel filling cooling water in cavity, tentatively lower the temperature and rough dusting; Flue gas declines along cooling water cavity outer wall afterwards, and temperature progressively reduces; Flue gas drops to below inner barrel, enters inner barrel, lowers the temperature further, further cools and dust removal by filtration at the filter place filling cooling water.Cold water Automatic water-filling mouth injects, and completes after heat exchange and flows out from delivery port, then through pond, water pump is circulated to water filling port, both saving water resources, realize flue gas cool-down again.Therefore, the utility model not only efficiency of dust collection is high, and cooling-down effect is very good, the sack cleaner after protection.
Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that the utility model can solve, technical scheme and these technical characteristics bring, will be described in further detail hereinafter by reference to the accompanying drawings.
