Description
Technical field
The present invention relates to filed of flue gas purification, particularly the drop in removing flue gas and the flue gas minimum discharge device of dust.
Background technology
China's atmosphere pollutants emission standards increasingly stringent at present, coal-burning power plant's dust emission concentration requires less than 10mg/m3, even lower, traditional dust arrester is difficult to meet requirement.The most a lot of coal-burning power plants install Wet type electric dust-removing device after desulfurization additional, although can meet the minimum discharge requirement of dedusting, but wet electrical dust precipitator floor space is big, investment height, and in operation, water consumption and power consumption are high.
Limestone/lime-gypsum method desulfurization technology is that in current sulfur method, technology application the most ripe, actual is most, the most stable of sulfur removal technology of operation conditions.But tradition desulfurizer is to tiny dust, liquid droplet capture weak effect, and after desulfurization, dust concentration is difficult to meet less than 10mg/Nm3Requirement, the flue gas of soot emissions simultaneously carries the substantial amounts of droplet containing Gypsum Fibrosum, thus can land around chimney substantial amounts of " gypsum rain " secretly, power plant's surrounding caused secondary pollution.Therefore improving flue dust and drop clean-up effect after Desulphurization for Coal-fired Power Plant, the dust arrester selecting investment and operating cost low is problem demanding prompt solution.
Summary of the invention
For above-mentioned deficiency of the prior art and defect, it is an object of the invention to provide a kind of coal-fired plant flue gas high effect dust cleaner.It has reduced investment, the advantage such as simple in construction, floor space consumption little, anhydrous and power consumption, and dust removing effects can meet the granular material discharged standard that country is strict completely.
In order to reach foregoing invention purpose, technical scheme realizes as follows:
A kind of ultra-clean dust arrester of Multi-stage spiral formula, it includes primary dust removing device and secondary ash collector.It is provided with perforated distributor between primary dust removing device and secondary ash collector.Perforated distributor is positioned at inner housing, and primary dust removing device includes flue gas air flap, shell, inner shell, sector, and sector is fixed on fixing axle.Secondary ash collector includes shell, inner shell, pipe and the helical blade being wrapped on pipe, and rear end is that flue gas is given vent to anger baffle plate and mudhole.It is structurally characterized in that, primary dust removing device and secondary ash collector arranged in series, and primary dust removing device and secondary ash collector share a shell and an inner shell.
Described a kind of Multi-stage spiral formula ultra-clean dust arrester shell is square, and inner shell is circular, and shell and inner shell are coaxially disposed, and inner shell uniform strip blowdown is stitched, and blowdown seam is axial arranged along inner shell.
Aforesaid a kind of ultra-clean dust arrester of Multi-stage spiral formula, is arranged in Desulphurization for Coal-fired Power Plant tower outlet rear pass, and multiple a kind of ultra-clean dust arresters of Multi-stage spiral formula are arranged in parallel and form a square module, and several modules are distributed in flue.Can also be installed in vertical gas pass in may be mounted at horizontal flue.
Aforesaid a kind of ultra-clean dust arrester of Multi-stage spiral formula, sector quantity is 6-12.
Aforesaid a kind of ultra-clean dust arrester of Multi-stage spiral formula, perforated distributor is positioned at inner shell, layout axially vertical with inner housing, and aperture is Φ 35, the outline of perforated distributor and the form fit of inner shell.
In above-mentioned a kind of ultra-clean dust arrester of Multi-stage spiral formula, described primary dust removing device and secondary ash collector, all material uses PP material, one-body molded.
Due to the fact that and have employed said structure, have the following advantages compared with the prior art and beneficial effect.
The most two different form of cyclone dust catcher is connected, and can be effectively improved the removal efficiency of fine dusts in absorption tower.
2. uniform strip blowdown seam on inner shell wall, in dust arrester, drop and the solid granule of rotating separation arrives inner shell wall, from inner shell wall, blowdown seam is derived, so that drop and solid granule thoroughly depart from flue gas, it is therefore prevented that flue gas is to drop and the reentrainment of fine particle thing.
3. the Flow Field Distribution situation in porous plate optimizes cleaner unit, eliminates flue gas Biased flow phenomenon, and flue gas passes through perforated distributor, enters at a high speed secondary ash collector with mode of jet, improves two-stage dust removal device to fine drop and the removal efficiency of dust.
4. using modular construction to arrange, transport is with easy for installation, quick.
5. use PP material, there is length in service life, feature corrosion-resistant, anti abrasive, be particularly suitable for application to the purification of the dusty gas of acid gas-containing, dust granules.
6. this device consumes without power consumption and water, and operating cost is low, simple in construction.
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
