Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, fume dust remover comprises: the primary filter 2 being positioned at gas access 10, gas access 10 is positioned at the bottom of deduster, and the air-spreading disk 3 be positioned at bottom deduster 1, air-spreading disk 3 is connected with gas access 10, air-spreading disk is immersed in absorbing liquid, it is a bent passage above air-spreading disk, first turning of bent passage is provided with spray thrower 4, spray thrower 4 is connected with water circulating pump 14 by pipeline, water circulating pump 14 is connected with bottom deduster by pipeline, second turning is provided with absorption felt 5, 3rd turning is provided with electrostatic precipitator 7, demister 6 is provided with in passage between described second turning and the 3rd turning, centrifugal fan 8 is provided with above described bent passage, the deduster inwall of the below of centrifugal fan 8 is provided with dust collecting trough 13, the top of centrifugal fan 8 is provided with HEPA screen pack 9, the top of HEPA screen pack 9 is gas vent 12, it is characterized in that, air-spreading disk 3, absorption felt 5, electrostatic precipitator 7, centrifugal fan 8, the top of HEPA screen pack 9 is respectively equipped with granule density detector 12, granule density detector 12 is connected with integrated manipulator.
During work, dusty gas enters from gas access 10, flow path as shown by arrows in FIG., first gas carry out primary filter through primary filter 2, bulky grain in gas is filtered by primary filter 2, primary filter 2 can be selected from metal net shaped filter or synthetic fibers filter, also can select that other are corrosion-resistant, the filter of long service life.Subsequently, dusty gas evenly injects the absorbing liquid bottom deduster 1 by air-spreading disk, and according to the character of dusty gas, absorbing liquid can be water, acid solution or alkaline solution.Such as the sulfur-bearing dusty gas of acidity, then absorbing liquid can select alkaline solution, as NaOH, aqua calcis.Dusty gas, through the purification of absorbing liquid, discharges from the liquid level of absorbing liquid, enters bent passage subsequently, and at the first turning of bent passage, be provided with spray thrower 4, spray thrower 4 sprays into absorbing liquid in passage, and absorbing liquid comes bottom Self-duster.The absorbing liquid of atomization contacts with dusty gas, grit is condensed and becomes large.Because the channel cross-section of bent passage is much smaller relative to the cross section of deduster, therefore after gas enters bent passage, flow velocity accelerates, air-flow at a high speed impinges upon on the absorption felt 5 at the second turning along passage, the felt body that high water suction selected by absorption felt 5, the material of highly-breathable is made, such as nylon, polyacrylonitrile, polyvinyl alcohol etc.The moisture air-flow high-speed impact of dust-laden on absorption felt 5 after, the absorbing liquid of dust-laden is adsorbed felt 5 and is adsorbed, and air-flow is further purified, and the gas after absorption flows to electrostatic precipitator 7 by bent passage.After absorption felt 5, the most absorbing liquid in air-flow is all absorbed by absorption felt 5, remaining absorbing liquid then be separated by the demister 6 that arranges in the passage between the second turning and the 3rd turning.Dusty gas after dehumidification strikes the 3rd turning, and the electrostatic precipitator 7 arranged with the 3rd turning contacts, and the grit in gas is further by electrostatic precipitator institute adsorbing separation.Purified gas enters in the upper space of deduster, the top of deduster is provided with centrifugal fan 8, the centrifugal fan 8 of High Rotation Speed plays the effect of two aspects, first, the rotation of centrifugal fan 8 improves the flow velocity of dusty gas, make the gas flow rate in bent passage become faster, impact is stronger; Moreover drive airflow centrifugal to rotate, make the grit in gas be thrown under the influence of centrifugal force on dedusting wall and fall in dust collecting trough afterwards, gas obtains further purification.After above-mentioned dust collecting process, the grit purification efficiency in gas reaches more than 98%, only remains the particle of a small amount of particle diameter below 5 μm.The topmost of deduster 1 is provided with HEPA screen pack 9, it adopts superfine fibre as filtrate, filter efficiency is high, resistance is low, be specifically designed to and remove remaining fine particulates in gas, purification efficiency reaches 99.99%, and after above-mentioned a series of purified treatment, clean gas discharges deduster 1 by gas vent 11.
Wherein above air-spreading disk, absorption felt, electrostatic precipitator, centrifugal fan, HEPA screen pack, be respectively equipped with granule density detector 12, granule density detector 12 is connected with integrated manipulator.Integrated manipulator monitors the data of each detector in real time, if find a certain granule density detector numerical exception, then can show rapidly that being specially which link has occurred fault, if the granule density detector numerical value above such as centrifugal fan is normal, and the granule density detector numerical exception above HEPA screen pack, then deducibility goes out HEPA screen pack and there occurs breakage or other abnormal conditions.Meanwhile, water circulating pump 14, centrifugal fan 8 and electrostatic precipitator 7 are also connected with integrated manipulator.If integrated manipulator finds the granule density detector numerical exception above absorption felt 5, then can control the absorbing liquid quantity delivered that water circulating pump 14 improves spray thrower 4, increase spray-absorption effect.If integrated manipulator finds the granule density detector numerical exception above centrifugal fan 8 or electrostatic precipitator 7, also centrifugal fan 8 can be controlled or electrostatic precipitator 7 takes corresponding action, to improve efficiency of dust collection.
Although describe technical scheme of the present invention in conjunction with specific embodiments above, but the present invention is not limited to this embodiment, when not changing principle of the present invention and instruction, those skilled in the art can make multiple remodeling and modification within the scope of the invention.
