Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In figure, coal gas diffusion at top of blast furnace dedusting noise reduction system, comprise blast furnace, batch can 1, batch can 1 is arranged several bleeder be communicated with batch can 1, blast furnace is also arranged several upcast 2 be communicated with blast furnace, wherein, every root bleeder of batch can 1 installs a set of fly-ash separator 3, the preferred tornado dust collector of fly-ash separator, the bleeder being communicated with batch can 1 is bleeder 1, fly-ash separator 3 is communicated with bleeder 1, and fly-ash separator 3 top arranges noise reduction dedusting tank 5, wherein fly-ash separator 3 is communicated with noise reduction dedusting tank 5, bleeder 1 is communicated with fly-ash separator 3 by a transverse tube 6, the other end of transverse tube 6 installs damping down valve and blank-plate valve 7 (blank-plate valve is for overhauling damping down valve) simultaneously, described blank-plate valve and damping down valve are close to, be connected on transverse tube 6, switching valve 8 is installed at the middle part of bleeder 1.
In noise reduction dedusting tank 5, basket strainer is set, the dedusting tank of noise reduction is simultaneously provided with two outlets, be respectively outlet one, outlet 29, its middle outlet one is connected with bleeder 2 10, valve 11 is diffused in the connection of bleeder 2 10 the other end, diffuse valve 11 the other end and connect bleeder 3 12, bleeder 3 12 is communicated with air.Outlet two is that the setting therefore exporting two can be selected as an outlet use for subsequent use.Conveniently overhaul noise reduction dedusting tank 5, a movable removable top cover 18 is set at the top of noise reduction dedusting tank 5, when maintenance, opens removable top cover.
Upcast on blast furnace is also to diffuse, and therefore fly-ash separator 3 is communicated with by a bleeder with upcast 2, and a upcast diffusion valve 13 is installed at the top of every root upcast 2 simultaneously.
Batch can is also arranged several ash-unloading tube 14, every root ash-unloading tube 14 is communicated with batch can 1, ash-unloading tube 14 installs unloading valve 15 simultaneously, dust stratification is facilitated to fall, blast furnace also arranges several equaler 16, equaler is original pipeline, and the utility model is provided with an equal valve 17 on equaler 16 simultaneously, the other end of one equal valve 17 is communicated with bleeder 2 10, and the gas of equal press operation enters batch can 1 by tornado dust collector and noise reduction tank.
Using method of the present utility model is as follows:
(1.) when batch can diffuses, first (damping down valve is in normally closed to close an equal valve 17, switching valve 8 is in often to be left), unloading valve 14, open equal row pressure diffusion valve (namely diffusing valve 11), dusty gas is first by tornado dust collector remove portion dust, then through noise reduction dedusting tank 5 remove portion dust again, finally cleaned gas is diffused in the middle of air.Equal press operation is carried out after diffusing end, by equal row pressure diffusion valve closedown, (damping down valve is in normally closed, switching valve is in often to be left), then unloading valve 14 is opened, open an equal valve 17, while all pressing to batch can 1, enter in batch can by the dust blowback in tornado dust collector, one time pressure-equalizing and discharging flow process terminates.
(2.) on the upcast 2 of blast furnace out-spreading, a pipeline (i.e. bleeder) is communicated with to tornado dust collector, at blast furnace staying in earlier stage, first the equal valve 17 of switching valve 8, is closed, open equal row pressure diffusion valve, damping down valve, unloading valve (upcast diffusion valve is in normally closed), first dusty gas is removed after part dust through tornado dust collector and is entered air.After later stage furnace pressure reduces, diffusion valve on upcast can be opened and diffuse with native system simultaneously, after diffusing end, the dust stratification in tornado dust collector be entered in batch can, pollution not produced to environment.
Blast furnace in the utility model, upcast and batch can are prior art, and the purpose of this utility model is dedusting.After adopting native system, owing to upcast being communicated with a bleeder to tornado dust collector, blast furnace staying initial stage diffused gas dust-laden height pollution on the environment problem can be solved.The dust collected after diffusing end enters batch can, returns blast fumance system.Environment is not produced and pollute.And because the fly-ash separator arranged is tornado dust collector, so do not need energy resource supply.The cyclone dust removal denoising device that the pipeline that batch can diffuses is arranged, not only can reduce the dustiness of diffused gas further, can play certain Noise Reduction simultaneously.Dust blowback on noise reduction dedusting tank basket strainer can be entered batch can by the coal gas all returned during pressure simultaneously, can effectively prevent basket strainer from blocking.
These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
