Background technique
When the converter current steel works was smelted, once dust collection of converter generally adopted wet dedusting.Contain a certain amount of dust and saturation water in the flue gas after the dedusting, through blower fan the time, the part dust is attached to fan blade, this causes fan operation after a period of time, because impeller generation dynamic balancing exceeds standard, must shut down, impeller is taken off, clean surface is sticking grey, has therefore reduced the running operating rate of converter, influence steel-making output.Blower fan adopts two water pipes to enter in the Blower Housing perpendicular to draught fan impeller at present, and water pipe is crooked certain angle in housing, with blower fan air intake direction, directly to impeller's water injecting washing; Other has two water pipes parallel with impeller, and the center line of centering directly enters Blower Housing, to the impeller flushing, and over against the air-out of blower fan, the draught fan impeller developing result, short blower fan operating life has only a week.
The model utility content
The purpose of this utility model is to provide a kind of dedusting fan impeller washing unit, and it can improve the operating life of blower fan, reduces the replacing number of times of draught fan impeller.
For realizing aforementioned purpose, dedusting fan impeller washing unit of the present utility model, be characterized in, comprise: water, atmospheric pressure modulating valve platform, comprise pressure regulator, be used to receive water and gas, and utilize pressure regulator with the air pressure adjustment of the hydraulic pressure of the water that receives and gas to the pressure of setting; Atomization mass and is connected with air pipe by water lines between this water, the atmospheric pressure modulating valve platform, is used to receive the water and the gas of the pressure with setting of water, the output of atmospheric pressure modulating valve platform, and the water and the gas that will have the pressure of setting atomize; And shower nozzle, join by pipeline with atomization mass, be used for the air-water mixture that is atomized of atomization mass output is sprayed to the dedusting fan impeller.
Described dedusting fan impeller washing unit, its further characteristics are, also comprise T shape pipe, and the outlet at the two ends of T shape pipe is respectively arranged with shower nozzle, join by pipeline between T shape pipe and the atomization mass, be used to receive the air-water mixture that is atomized of atomization mass output.
Described dedusting fan impeller washing unit, its further characteristics are that the desired location of shower nozzle in dedusting fan has following condition: the air-water mixture of the fan shape of shower nozzle ejection is parallel to the blade of impeller.
Described dedusting fan impeller washing unit, its further characteristics are that water, atmospheric pressure modulating valve platform are connected respectively with a plurality of atomization mass.
Described dedusting fan impeller washing unit, its further characteristics are, dedusting fan impeller for one-sided air draught, water, atmospheric pressure modulating valve platform are connected respectively with two atomization mass, T shape pipe symmetric arrangement in dedusting fan that two atomization mass connect respectively, and arrange 4 shower nozzles in corresponding these T shape pipes.
Described dedusting fan impeller washing unit, its further characteristics are, dedusting fan impeller for the bilateral air draught, water, atmospheric pressure modulating valve platform are connected respectively with two atomization mass, T shape pipe symmetric arrangement in dedusting fan that two atomization mass connect respectively, and arrange 8 shower nozzles in corresponding these T shape pipes.
Described dedusting fan impeller washing unit, its further characteristics be, shower nozzle apart from blade 60mm to 100mm.
The beneficial effects of the utility model are:
Adopt this draught fan impeller washing unit that draught fan impeller is carried out on-line cleaning, air-water mixture after the atomizing forms water membrane on the draught fan impeller surface, clean the sticking ash of impeller surface simultaneously, reduce ash sticking on the draught fan impeller surface, the blower fan operating life prolongs more than 2 times, reduce the replacing number of times of draught fan impeller, reduce working strength of workers significantly, improve steel-making output.
Description of drawings
Fig. 1 is the schematic representation of the structure of dedusting fan impeller washing unit of the present utility model.
Embodiment
As shown in Figure 1, water and gas are delivered to control valve platform 10 by water lines 11 and air pipe 12 respectively, arrive the pressure of setting by adjusting water of the controlling device in the control valve platform 10 and atmospheric pressure, water that regulates and gas are delivered to atomization mass 6 by water lines 8, air pipe 9 respectively again.Water and gas atomize in atomization mass 6, and the air-water mixture after the atomizing manages 4 through the T shape that air-water mixture pipeline 5 is delivered in the Blower Housing, deliver to shower nozzle 1 through T shape pipe 4 again, and shower nozzle 1 sprays air-water mixture to draught fan impeller 2 with the position of setting.T shape pipe 4 has 60 millimeters apart from blower fan axle 3, and shower nozzle 1 has 80 millimeters (also can at 60mm between the 100mm) apart from blade 2, and the atomized water of the spraying of shower nozzle 1 becomes fan-shaped, is parallel to the blade of impeller 2.Form water membrane on draught fan impeller 2 surface, clean the sticking ash on impeller 2 surfaces simultaneously, reduce ash the fouling on the sticking of draught fan impeller 2 surfaces, impeller 2 surfaces firmly, the situation of difficult drop-off takes place.
Adopt this device fan life to improve more than 1 times.With 80 tons of converters is example, and the replacement cycle of impeller was brought up to 15-20 days by original 7-10 days.Each shutdown deashing 8 hours.After the improvement; the minimizing of 20 days each operation period was once shut down 8 hours, per 8 hours steel-making 10 stoves, the 1 year many steel-making of accumulative total 365*80% (operating rate)/20*10*80 ton/stove=11680 ton; by 200 yuan of calculating of ton steel profit, 1 year can extra earning 200*11680=2336000 unit.
The utility model volume is little, safeguards simplyr, and operation is than being easier to, and the back extra earning of going into operation is more remarkable, is easy to popularization.
