Abstract
The present invention discloses a dust removing method which is characterized in that polluted air exhausted by an organic fertilizer production line is conveyed to a dust removing chamber 1; dust in the polluted air is led to enter a filter 2 by following water flow by making use of the methods of speed reduction through depressurization and dust removal through moistening; floating objects are filtered out by the filter 2 and are discharged out of the filter 2; precipitates enter a precipitation chamber 4 by following the water flow, and are discharged by a dust removing machine 6 in a timely mode; ozone with high concentration is produced by an electric deodorizing device 7, the ozone and the polluted air simultaneously enter the dust remover 1 to complete a deodorizing process in the humidifying process, and then, the ozone is converted into oxygen; lime powder is added to a dust inlet machine 5 to desulphurize SO2 in the air, then, Ca (OH) 2 and SO2 are converted into CaSO4 and H2O. If the polluted air is processed by adopting the method, good effects can be achieved. The dust removing method can be widely applied to air purifying fields.
Description
Technical field
The present invention relates to a kind of air purification method, exactly is a kind of dust collection method.
Background technology
China is the big country of outlet chicken, duck product, and the export volume of Shandong Province accounts for 1/3 of national export volume, and manufacturer spreads all over all parts of the country, and management style is from hatching, culture, slaughter, quick-frozen, being packaged into finished product one package service.The ight soil that the chicken farm produces unprocessed low adding, sold the peasant and make organic fertilizer, caused the approach of spread of germs.Along with the needs of living standards of the people, the sharp increase of pollution-free food export volume, a large amount of fertilizer factories has appearred again in the whole nation, nearly more than 20,000 families.Fertilizer factory with chicken droppings ight soil by fermentation, processes such as drying and sterilizing, pulverizing, batching, granulation becomes multi-purpose fertilizer, improved the economical and practical value of chicken droppings ight soil, broken off the breeding approach of various bacteriums again.But in process of manufacture, a large amount of dusts, foul smell are by discharging (dust every day discharge 3-4 cubic meter) in the chimney, severe contamination place ambient air environment, 100 square kilometres of contaminated areas, peripheral peasant's normal life and Ankang have been influenced, caused environmental pollution, suffered the fine of Environmental Protection Agency, the masses also have complaints.Existing dust collection method no matter be air-conditioning, ventilation adopt be screen pack, filter, after long-time the use, can result in blockage, reduce the logical usefulness in chamber.
Summary of the invention
Purpose of the present invention is to provide a kind of and can effectively carry out dust removal, go out dirt, and long-time use the method after, cleaner can not reduce the dust collection method of dust removing effects.
A kind of dust collection method is characterized in that:
A, the contaminated air of from the organic fertilizer production line, discharging, enter into dirt pocket 1 from the air intake 11 of deduster, utilize two kinds of methods of step-down deceleration and humidification dedusting, airborne dust is removed, pure air is discharged from air outlet slit 12 under the effect of air-introduced machine;
Dust in B, the contaminated air enters filter 2 with current in dirt pocket 1, filter 2 will float the thing that wafts and leach, and discharge outside the filter 2, sediment enters A mud chamber in the mud chamber 4 with current, current enter into the B mud chamber again from the A mud chamber, in water flowed process, sediment accumulated in the A mud chamber and is regularly discharged by dust exhaust machine 6, and the current in the B mud chamber enter into dirt pocket 1 again with water circulating pump 9 and circulate next time;
Output ozone with high concentration in C, the electronics odor eliminator 7 enters into deduster 1 simultaneously with contaminated air, finishes the taste removal process in humidification, O
3→ O
2
D, in dust entrance machine 5, add pulverized limestone, to the SO in the contaminated air of from the organic fertilizer production line, discharging
2Carry out desulfurization, Ca (OH)
2+ SO
2→ CaSO
4+ H
2O.
By taking above method, handle the contaminated air of discharging from chimney in process of production, can realize:
1. the organic dust in the recovery gas, turn waste into wealth (dust removal efficiency 93%);
2. the elimination peculiar smell purifies air, and reduces environmental pollution;
3. in processing procedure, can reduce air themperature, avoid stopping up draught fan impeller, burn out motor, can prolong the service life of air-introduced machine.
Description of drawings
Fig. 1 is for adopting apparatus structure schematic diagram used in the present invention
1 dirt pocket, 2 filters, 3 discharge buckets, 4 mud chambers, 5 dust entrance machines, 6 dust exhaust machines, 7 electronics taste removals, 8 automatically controlled 9 water circulating pumps, 10 pedestals, 11 air intakes, 12 air outlet slits, 13 dividing plates, 14 communication port A, the B of mud chamber, mud chamber among the figure
The specific embodiment
At first device used in the present invention is adopted in explanation, mainly is made up of dirt pocket 1, filter 2, ash entrance chamber 5, dust exhaust machine 6, pedestal 10, is provided with dirt pocket 1 on the top of pedestal 10, is respectively equipped with air intake 11 and air outlet slit 12 in the two side ends of dirt pocket; In the middle cavities of pedestal 10, the bottom of dirt pocket 1 is respectively equipped with filter 2, dust entrance machine 5, the upper end of filter 2 is connected by the bottom of water pipe with dirt pocket 1, the bottom of filter 2 is provided with discharge bucket 3; Be provided with mud chamber 4 in the bottom of pedestal 10, a side of 4 is provided with dust exhaust machine 6 in the mud chamber, mud chamber 4 is divided into two A of mud chamber and B that communicate by dividing plate 13, a side, air outlet slit 12 ends at the B of mud chamber are provided with water circulating pump 9, and the upper end of water circulating pump 9 is connected by the bottom of water pipe with dirt pocket 1; On the lower end of air intake 11, pedestal 10, be provided with electronics odor eliminator 7 and automatically controlled 8.
Now specify process of the present invention:
A, the contaminated air of discharging from the organic fertilizer production line enter into dirt pocket 1 from air intake 11, utilize two kinds of methods of step-down deceleration and humidification dedusting, and airborne dust is removed, and pure air is discharged from air outlet slit 12 under the effect of air-introduced machine;
Dust in the contaminated air of B, fertilizer factory can be divided into two parts substantially: sediment, drift.These dust are left in the water through having more than 93 percent behind dirt pockets 1, enter filter 2 with current, and filter 2 leaches floating thing, and discharges outside the machine automatically.Sediment enters A mud chamber in the mud chamber 4 with current, current enter into the B mud chamber again from the A mud chamber, in water flowed process, sediment accumulated in the A mud chamber and is regularly discharged by dust exhaust machine 6, and the current in the B mud chamber enter into dirt pocket 1 again with water circulating pump 9 and circulate next time;
Output ozone with high concentration in C, the electronics odor eliminator 7 enters into deduster 1 simultaneously with contaminated air, finishes the taste removal process in humidification, O
