Abstract
The utility model provides a blow-down system at the bottom of a chimney, which comprises the chimney and a dust accumulation platform arranged in the chimney, wherein a dust accumulation pool is arranged below the dust accumulation platform at the bottom of the chimney, the dust accumulation platform is connected to the bottom of the dust accumulation pool by a dust accumulation passage, the dust accumulation passage and the dust accumulation pool are communicated by an accumulated dirt outlet, and the node position of the dust accumulation platform and the bottom of the chimney is provided with a slope with a certain gradient. The blow-down system at the bottom of the chimney has the beneficial effects that accumulated dust and accumulated flowing liquid on the dust accumulation platform are introduced into the dust accumulation pool through the dust accumulation passage by arranging the dust accumulation pool at the bottom of the chimney, the accumulated dust can be better discharged successfully, and the occurrence of the corrosion of the chimney and equipment is prevented; and moreover, the decontamination operation can be carried out under the condition that furnace shutdown is not needed, and the cleaning of the accumulated dust of the chimney is greatly convenient.
Description
Technical field
The utility model relates to the chimney treatment technology, relates to a kind of aseptic technic of chimney bottom particularly.
Background technology
The height of industrial chimneys such as thermal power plant is generally about 150m-270, in chimney bottom a dust stratification platform is set and is used for sedimentation dust stratification and long-pending acid solution, cross beam under the dust stratification platform is built with chimney bottom, is generally xoncrete structure, chimney wall inner lining refractory block or glass block.Dust stratification platform formwork secondary on cross beam is built, and fills out loose fill type insulant in the seam when chimney lining is laid bricks.Need after desulfurization, enter atmosphere during chimney emission, and the exhaust gas temperature after the desulfurization is generally at 40-50 ℃, water content height, high humidity in the flue gas, the plume rise diffusivity is low, therefore form water smoke in chimney, flue gas has the droplets agglomerate that contains acid in a large number to come out below dew point, not only contaminated environment but also bring corrosion to equipment, therefore, a large amount of dust stratification liquid, dust stratification things need be discharged chimney as soon as possible on the dust stratification platform.
Dust stratification liquid on the existing dust stratification platform and dust stratification thing are generally discharged chimney by blow-off pipe is set in chimney bottom, owing to be subjected to the restriction of caliber, chimney bottom is easy to be stopped up by dust stratification, cause acid solution to gather, and might flow backwards to flue, also be the one of the main reasons that dust stratification platform, flue bottom and flue and chimney joint portion isolate failure.
The utility model content
The utility model provides a kind of chimney bottom drainage for solving the problems of the technologies described above.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of chimney bottom drainage, comprise chimney and be arranged on the interior dust stratification platform of chimney, it is characterized in that: the dust stratification platform below of described chimney bottom is provided with a dust stratification pond, described dust stratification platform is connected to bottom, dust stratification pond by the dust stratification passage, the dust stratification passage is communicated with by the contamination outlet with the dust stratification pond, and the node place of described dust stratification platform and chimney bottom is provided with the slope with certain slope.
Better, the sidewall in described dust stratification pond is provided with leakage fluid dram, and the height of described leakage fluid dram is greater than the height of described contamination outlet.
Better, described slope is provided with the acid-resistant and anti-high-temperature material layer.
Better, the inwall in described dust stratification pond is provided with the acid resisting material layer.
Better, the gradient on described slope is not less than 1%.。
The beneficial effects of the utility model are, by the dust stratification pond is set in chimney bottom dust stratification on the dust stratification platform and long-pending flow liquid are fed in the dust stratification pond by the dust stratification passage, can not only better dust stratification successfully be discharged, prevent from chimney and equipment are produced corrosion, and the work of under the situation that does not need blowing out, can removing contamination, the dust stratification that greatly facilitates chimney is cleared up.
Description of drawings
Fig. 1, structure chart of the present utility model.
Among the figure, 1 inner wall of stack, 2 dust stratification platforms, 3 dust stratification ponds, 4 dust stratification passages, the outlet of 5 contaminations, 6 slopes, 7 leakage fluid drams, 8 acid-resistant and anti-high-temperature material layers, 9 acid resisting material layers.
The specific embodiment
A kind of chimney bottom drainage, referring to accompanying drawing 1, comprise inner wall of stack 1, be arranged on the dust stratification platform 2 of inner wall of stack 1 inboard, dust stratification platform 2 belows of chimney bottom are provided with dust stratification pond 3, dust stratification platform 2 is connected to the bottom in dust stratification pond 3 by dust stratification passage 4, dust stratification passage 4 is communicated with by contamination outlet 5 with dust stratification pond 3, dust stratification platform 2 is provided with the slope 6 with certain slope with the node place of chimney bottom, discharge for amassing flow liquid more easily, the sidewall in dust stratification pond 3 is provided with leakage fluid dram 7, and the height of leakage fluid dram 7 overflows from contamination outlet 5 to prevent the cigarette in the chimney greater than the height of contamination outlet 5.
Because long-pending flow liquid is an acid solution, so the domatic acid-resistant and anti-high-temperature material layer 8 that is provided with on slope 6, slope 6 is designed to certain slope so that long-pending flow liquid flows out smoothly, and the inwall in dust stratification pond 3 also is provided with acid resisting material layer 9 to strengthen decay resistance.The gradient on slope 6 is designed to be not less than 1%.
The utility model feeds dust stratification on the dust stratification platform and long-pending flow liquid in the dust stratification pond by the dust stratification passage by the dust stratification pond is set in chimney bottom, can not only better dust stratification successfully be discharged, prevent from chimney and equipment are produced corrosion, and the work of under the situation that does not need blowing out, can removing contamination, greatly facilitate the dust stratification cleaning of chimney, construction is transformed simple, has good economic benefits.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the utility model although this specification has been described in detail the utility model with reference to each above-mentioned embodiment; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
