Description
The utility model relates to the boiler desulfurization dust arrester, and particularly a kind of miniature boiler is energy-conservation, desulfurization, dust removal integrated plant.
In the prior art small scall coal-fired boiler is administered, is made fume emission reach emission standard of air pollutants for boilers, but in improvement, also depositing following problem:
1, air-introduced machine band water, fan belt water not only influences exerting oneself of blower fan, and owing to contain the composition of sulfurous acid and sulfuric acid mist, has corroded draught fan impeller and casing, has shortened the life cycle of air-introduced machine.
2, the small low-voltage boiler mostly adopts the wing cast iron gilled tube economizer to flue gas waste heat recovery at present, in use causes cigarette ash to stop up easily, directly has influence on boiler combustion.Operating pressure was higher than boiler pressure during cast iron gilled tube economizer used, and belonged to pressure-vessel, operated strictly for this reason, needed monitoring to use, and the flue-gas temperature time requirement of being fed water influences, and the exhaust gas temperature instability is unfavorable for wet scrubbing desulfurization requirement.
3, since miniature boiler, particularly 2T/h with assistant's baker because the furnace type structure aspect, exhaust gas temperature is generally higher, this has not only wasted the energy, and is unfavorable for the improvement of flue gas desulfurization and dedusting.
4, at present in the improvement of arcola desulfurization and dedusting, very inconvenient to sedimentary removing, influence treatment facility and normally move.
The purpose of this utility model is: provide that a kind of miniature boiler is energy-conservation, desulfurization, dust removal integrated plant, it can be in the too high cooling and purification treatment of miniature boiler flue gas and stove, kiln exhaust gas temperature, collect energy-conservation, desulfurization, dust removal integrated the time, reach the energy-saving efficiency height, operating cost is low, floor space is little, desulfurization and dedusting is effective, operation is simple, small investment, purpose that comprehensive utilization ratio is high.
Formation of the present utility model: form by deduster, flue gas energy saving cooler, air-introduced machine, spray desulfurizing tower, sedimentation basin, neutralization pond and water bath dust-removing chamber, deduster (1) is connected with flue gas energy saving cooler (2), flue gas energy saving cooler (2) is connected with air-introduced machine (4) by air inlet duct (3), air-introduced machine (4) connects spray desulfurizing tower (6) by air-introduced machine discharge head (5), goes up in water bath dust-removing chamber (11) spray desulfurizing tower (6), water pump (7), flue (8), sedimentation basin (9) (12) and neutralization pond (10) are installed.Heat exchanger tube (18) upper end is upper smoke box (27), the lower end is lower smoke box (25), lower smoke box (25) is connected with ash dropping hopper (20) with flue (17) respectively, be installed in the casing (19), exhanst gas outlet (28) and upper smoke box cover plate (13) are arranged on the upper smoke box (27), on the upper smoke box cover plate, be welded with guide vane (14), smoke inlet (16) is arranged on the flue (17), water inlet (15), delivery port (24) and telethermometer silk seat (26) are arranged on casing (19).
Compared with the prior art, the utility model is rational in infrastructure, and during boiler smoke process flue gas energy saving cooler, dust has been removed about 60%, and when entering air-introduced machine, flue gas is a dry flue gas, has overcome the fan belt water problem.
The flue gas energy saving cooler is a kind of water---the gas heat exchanger, its heat transfer rate height as long as control the flow (forced circulation) of water well, just can be controlled the flue gas discharge temperature effectively.
Energy-saving effect is obvious, with exhaust smoke level 5000m
3About/h, about 350 ℃ of flue-gas temperatures, exhaust gas temperature is controlled at about 120 ℃, equipment operation 1 hour, the 152000KJ～200000KJ that can conduct heat can make the 2m of inflow temperature about 20 ℃
3Water reaches more than 40 ℃, is equivalent to save about the thermal efficiency 70% boiler consumption coal 15kg.Hot water can also can be connected with softened water tank for taking a shower, and improves the boiler feed water temperature, reaches the purpose of energy savings.
Sediment is outdoor at water bath dust-removing, is convenient to remove, and the solution after the desulfurization can be recycled behind neutralization pond and milk of lime reaction regeneration, and therefore, non-wastewater discharge does not cause secondary pollution.
Low (the about 80-100mmHO of this device flue gas resistance
2), it has changed the situation that former dust-removal and desulfurizing overall process is all carried out under condition of negative pressure, made full use of centrifugal blower air outlet positive pressure head and carried out desulfurization and dedusting.
This device adopts and does, wet two-stage dedusting, the efficiency of dust collection height.Two alkaline process washing desulphurizations are adopted in desulfurization, belong to gas, liquid reaction, and rate of sulphur expulsion is fast, efficient height, calcium utilization height.
This device also can be used for other stove, kiln cooling, dedusting, purifies flue gas and recovery waste heat.
The flue gas energy saving cooler belongs to heat exchanger class normal pressure product, has overcome the stifled grey shortcoming of cast iron gilled tube economizer and the characteristics of band pressure work, and the heat exchange effect is better than cast iron gilled tube economizer.
Make and install easily, simple to operate, as long as connect the import and export flue flange, add running water or soft water and can move use.
