Background technology
Along with The development in society and economy, industrial development is also more and more rapider, but the dust that brings in industrial production is also a lot, and these dust mainly are present in the gas, therefore just corresponding dust arrester need be set.The Bed Filtration dust arrester as quartz sand etc., has unique superiority in the gas cleaning at high temperature field because of adopting resistant to elevated temperatures filtrate.But traditional Bed Filtration dust arrester need be by rake and transmission mechanism when reverse gas cleaning, and ash-removal effect is bad, and operating efficiency is not high.
The patent No. is to disclose a kind of combustion inferior coal boiler electricity granular-layer duster in the utility model patent specification of ZL88201515.X, its is made up of pre-charged device of installation and dirt gas part flow arrangement in expansion chamber of boiling reverse gas cleaning gravel bed filter, this device has been cancelled traditional rake and transmission mechanism, relatively simple for structure, the energy dry method, efficiently, low-resistance is collected the flue dust that the combustion inferior coal boiler is discharged, but this device makes the air distribution plate inequality of being heated of supporting filtrate owing to structural reason, yielding and generation is leaked and is expected and gas leakage, can not be applicable to the occasion that high temperature or temperature fluctuation are big.
Summary of the invention
Technical problem to be solved by this invention provides a kind of granular-layer dust precipitator that can be applicable to the occasion that high temperature and temperature fluctuation are big.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of granular-layer dust precipitator, comprise shell body and be arranged on the filter of one deck at least in the described shell body along short transverse, the top of described shell body is provided with the ash-laden gas import, the lower end of described shell body is provided with the dust outlet, described filter is provided with independently gas reversing arrangement, be connected with pure qi (oxygen) house steward and blowback air house steward on the described gas reversing arrangement, described filter comprises at least one filter element, described filter element is an inner housing, described inner housing is provided with blow vent and breather pipe, be provided with stratum granulosum and air distribution plate in the described inner housing, described blow vent is arranged on the top of described stratum granulosum, described breather pipe is arranged on the below of described stratum granulosum, and described breather pipe laterally passes described shell body and is connected with described gas reversing arrangement.
Described gas reversing arrangement is the independently reversal valve that is connected with described breather pipe, and described reversal valve is connected with described blowback air house steward with described pure qi (oxygen) house steward respectively.
Described gas reversing arrangement is made up of with the ventilation arm that is connected with described reversal valve reversal valve, and described reversal valve is connected with described blowback air house steward with described pure qi (oxygen) house steward respectively, and described breather pipe is connected on the described ventilation arm.
Be provided with pre-distribution porous plate in the described inner housing, described pre-distribution porous plate is arranged between described air distribution plate and the described breather pipe.
Described filter comprises the filter element more than two, rectangular in the horizontal direction distribution of described filter element or distribution ringwise.
The wall of described shell body is provided with bleeding point, and described bleeding point is arranged between described filter and the outlet of described dust.
Described bleeding point by bleed and dust arrester be communicated with described ash-laden gas import.
The cross section of described shell body is circular, tangentially is connected between described ash-laden gas import and the described shell body.
The cross section of described inner housing is circular fan-shaped or trapezoidal.
The cross section of described inner housing is square, and the cross section of described shell body is square.
Compared with prior art, the invention has the advantages that inner housing is surrounded by thermal current when dust removal by filtration, the inner housing each several part expands with heat and contract with cold evenly, and the thermal deformation resistant performance is good, makes this deduster can be used in high temperature and the changeable occasion of temperature, and is applied widely; Again owing to be provided with one deck filter at least, and each filter passes through all independently that the gas reversing arrangement is connected with the blowback air house steward with the pure qi (oxygen) house steward respectively, makes each stratum granulosum deashing alone, and fluidisation deashing successively from top to bottom, dust is transmission downwards successively, and ash-removal effect is good; Because shell body is tangentially introduced in the ash-laden gas import, under centrifugal action, obtain pre-dedusting again, alleviate the filtration load of stratum granulosum, and the wall of shell body is provided with bleeding point, can extract the dust that clears from stratum granulosum out filter.
