Technical field
The utility model relates to fluid bed high-temperature dust removal system, especially relates to multi-layer ceramics filtrate fluid bed high-temperature dust removal system.
Background technology
In traditional high temperature fume dust removal technology, conventionally adopt three grades of cyclone dust collectors series connection dedusting methods.But because high-temperature dust-containing flue gas has the characteristic that viscosity is large, dust granules temperature is high, there is the defect that purification efficiency is low in above-mentioned dedusting method; And the dedusting method that adopts electric cleaner exists that corona discharge is unstable, electrode life is short, to problems such as smoke components sensitivity, high-temperature insulations; Adopt wet method normal temperature purifying and dedusting method, lost again sensible heat and latent heat a large amount of in high-temperature flue gas.There is at present the particle filtering of employing dust arrester to carry out dust removal and filtration to high-temperature dusty gas, but this particle filtering dust arrester is fixed bed while conventionally filtering, during anti-cleaning, it is ebullated bed, therefore dust removal and filtration is interrupted production process, filter efficiency and utilization rate of equipment and installations are lower, and required filter area is also larger.
Summary of the invention
The utility model object is to provide a kind of clean, efficient multi-layer ceramics filtrate fluid bed high-temperature dust removal system.
For achieving the above object, the utility model is taked following technical proposals:
Multi-layer ceramics filtrate fluid bed high-temperature dust removal system described in the utility model, comprises granule filter material thermopnore; Described granule filter material thermopnore is comprised of the coarse granule filtrate thermopnore and the fine grained filtrate thermopnore that are arranged in housing; Described a plurality of vertical filtering layer passage thick, that fine grained filtrate thermopnore forms by screen cloth forms; The level on the housing of coarse granule filtrate thermopnore one side that is positioned at is provided with dusty gas import, and the level on the housing of fine grained filtrate thermopnore one side that is positioned at is provided with purified gas outlet; Case top is provided with respectively and thick, the vertical filtering layer channel entrance of fine grained filtrate thermopnore communicates thick, fine grained filtrate hopper, and thick, the vertical filtering layer channel outlet of fine grained filtrate thermopnore is communicated with thick, the fine grained media regeneration device that are located at lower housing portion respectively; Described filtrate outlet thick, fine grained media regeneration device is communicated with corresponding described thick, fine grained filtrate hopper by lifter respectively; Slightly, the exhaust outlet of fine grained media regeneration device is communicated with cyclone separator by pipeline respectively; Described cyclone separator air outlet is communicated with described dusty gas import.
Described lifter is that wind send elevator; Described thick, fine grained media regeneration device forms by housing and the vibratory sieve established within it; Described vibratory sieve is divided into upper and lower chamber by described housing; Described upper chamber is communicated with and is communicated with described cyclone separator by pipeline with corresponding vertical filtering layer channel outlet respectively; Described lower chambers send elevator to be communicated with by air exhauster with corresponding wind respectively.
The utility model advantage is simple in structure, practical, and dust removal and filtration runs without interruption continuously.For particle diameter be less than 2.26 μ m, particle number accounts for 90% high-temperature dusty gas, filtering gas speed is 0.33m/s, filter efficiency is up to more than 99.9 %.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, multi-layer ceramics filtrate fluid bed high-temperature dust removal system described in the utility model, comprises granule filter material thermopnore; Described granule filter material thermopnore is comprised of the coarse granule filtrate thermopnore 1 and the fine grained filtrate thermopnore 2 that are arranged in housing; Described a plurality of vertical filtering layer passage 4 thick, that fine grained filtrate thermopnore 1,2 forms by screen cloth 3 forms; The level on the housing of coarse granule filtrate thermopnore 1 one sides that is positioned at is provided with dusty gas import 5, and the level on the housing of fine grained filtrate thermopnore 2 one sides that is positioned at is provided with purified gas outlet 6; Case top is provided with respectively and thick, vertical filtering layer passage 4 imports of fine grained filtrate thermopnore communicate thick, fine grained filtrate hopper 7,8, and vertical filtering layer passage 4 outlets of thick, fine grained filtrate thermopnore are communicated with thick, the fine grained media regeneration device 9,10 that are located at lower housing portion respectively; Described filtrate outlet thick, fine grained media regeneration device 9,10 is communicated with corresponding described thick, fine grained filtrate hopper 7,8 by lifter 11,12 respectively; Slightly, the exhaust outlet of fine grained media regeneration device 9,10 is communicated with cyclone separator 13 by pipeline respectively; Described cyclone separator 13 air outlets are communicated with described dusty gas import 5.
Described lifter 11,12 is elected wind as and is sent elevator; Described thick, fine grained media regeneration device 9,10 forms by housing and the vibratory sieve 14 established within it; Described vibratory sieve 14 is divided into upper and lower chamber by described housing; Described upper chamber is communicated with and is communicated with described cyclone separator 13 by pipeline with corresponding vertical filtering layer passage 4 outlets respectively; Described lower chambers send elevator to be communicated with by air exhauster 15,16 with corresponding wind respectively.
The utility model operation principle is summarized as follows:
During the utility model operation, high-temperature dust-containing flue gas is cross-flow from dust-laden gas feed 5 and enters, first 2~5 mm porous ceramics particles in the vertical filtering layer passage 4 of coarse granule filtrate thermopnore 1 carry out coarse filtration (thick dedusting), the big dust particle of the overwhelming majority in entrap gas, now coarse granule filter material layer shows as deep-bed filtration, held more than 90% dust, but 20% of not enough overall presure drop falls in resistance.Gas through coarse filtration dedusting carefully filters (smart dedusting) through 0.5~1 mm quartz sand in the vertical filtering layer passage 4 of fine grained filtrate thermopnore 2 again, obtained leak the fine dust of coarse granule filter material layer, now fine grained filter material layer shows as surface filtration, so filter efficiency is greatly improved.
Purified gas is discharged from purified gas outlet 6, flow through respectively dust thick, that fine grained filtrate carries interception in thick, the vertical filtering layer passage 4 of fine grained filtrate thermopnore 1,2 from top to bottom and flow in corresponding thick, fine grained media regeneration device 9,10, through regenerator 9,10 internal vibrations sieves, clean up slightly, fine grained filtrate is sent in corresponding lifter 11,12 and recycles; Be cleaned the gas that gets off to take dust simultaneously and enter cyclone separator 13, through cyclone separator 13, from the dust going out, be transported to grey storehouse, high-temperature gas recycles again in dust-laden gas feed 5 enters granule filter material thermopnore.
