The bag type dust collector has the advantages that: the structure is rational, the service life and the dedusting efficiency of the filter bag are effectively improved, the operation cost is reduced and secondary dust rising can be avoided when deashing operation is carried out.
Description
Technical field
The utility model relates to a kind of sack cleaner, particularly a kind of sack cleaner that prevents the high temperature naked light.
Background technology
Sack cleaner now has been widely used in the industries such as metallurgy, building materials, cement, mine.Sack cleaner mainly is to filter out dust in flue gas by the filter bag of being made by fibrous material, and realizes the purpose of smoke abatement and dust control.Because its temperature of flue gas of discharging from kiln is very high, though now taked in air inlet pipe, to set up as cooling installations such as economizers, but flue gas still can surpass the heat resisting temperature of filter bag, even in flue gas, carry unburnt Mars secretly, thereby seriously reduced the service life of filter bag and dust removing effects, the efficiency of dust collection of deduster, increased the operating cost of deduster.In addition, the existing collected dust of sack cleaner particularly adopts bulk vehicle to clear up, when transporting, very easily produces reentrainment of dust in the deashing operation, exists secondary pollution problem.
The utility model content
For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, effectively improve life of bag filter and efficiency of dust collection, reduction operating cost and avoid the sack cleaner that prevents the high temperature naked light of reentrainment of dust.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises body, filter bag, spraying and blowing organ, intake stack, ash bucket and switch board; Be respectively equipped with temperature measurer I, vent valve and air intake valve, temperature measurer II before and after the intake valve in admission line; Above-mentioned vent valve and standby dedusting pond interlink.When sack cleaner was worked, when temperature measurer I measured temperature was higher than the heat resisting temperature of filter bag, then the air intake valve was opened, and fed the air of low temperature in admission line, to reduce the temperature of flue gas; If the air intake valve is opened 5-10 after second, the measured temperature of temperature measurer II still is higher than the heat resisting temperature of filter bag, then opens vent valve, and with an overheated flue gas moment discharging part, the flue gas that is discharged enters in the standby dedusting pond and carries out smoke abatement and dust control; After the measured temperature of temperature measurer II is lower than the heat resisting temperature of filter bag, close the air intake valve; Thereby overheated flue gas is not entered in the body of sack cleaner, guaranteed the service life of filter bag.
Air inlet place at body is provided with the venetian blind type deflector, so that larger particles and unburnt grey star all directly clash into deflector and fall in the ash bucket in the flue gas.
In ash bucket, be provided with spray head; When the dust accumulation in the ash bucket to need carry out deashing the time, then open spray head, thereby produce reentrainment of dust when avoiding the deashing operation.
Above-mentioned temperature measurer I, vent valve, air intake valve, temperature measurer II and spray head all link to each other with switch board.
The beneficial effects of the utility model are: it is rational in infrastructure, effectively improves life of bag filter and efficiency of dust collection, reduces operating cost, produces reentrainment of dust when having avoided the deashing operation simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that body, 2 is that spraying and blowing organ, 3 is that air-introduced machine, 4 is that filter bag, 5 is that ash bucket, 6 is that spray head, 7 is that admission line, 8 is that vent valve, 9 is that intake valve, 10 is that air intake valve, 11 is that temperature measurer I, 12 is that temperature measurer II, 13 is that deflector, 14 is that standby dedusting pond, 15 is a switch board.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Pocket type divider described in the utility model comprises body 1, filter bag 4, spraying and blowing organ 2, ash bucket 5 and switch board 14; The inside of body 1 is separated into two ones up and down, promptly divides air-purifying chamber and filter chamber; The both sides of body 1 are respectively equipped with air inlet and gas outlet; Be provided with venetian blind type deflector 13 at the air inlet place, and the admission line 7 that has intake valve 9 is housed; The place, gas outlet establishes air-introduced machine 3; Some filter bags 4 hang in the filter chamber, and spraying and blowing organ 2 is located in the air-purifying chamber; The bottom of body 1 is provided with ash bucket 5, is provided with spray head 6 in the ash bucket 5.Intake valve 9 front and back in admission line 7 are respectively equipped with temperature measurer I11, vent valve 8 and air intake valve 10, temperature measurer II12; Above-mentioned vent valve 8 interlinks with standby dedusting pond 14.Above-mentioned spraying and blowing organ 2, intake valve 9, temperature measurer I11, vent valve 8, air intake valve 10, temperature measurer II12 and spray head 6 all link to each other with switch board 14.
When sack cleaner was worked, when temperature measurer I 8 measured temperatures were higher than the heat resisting temperature of filter bag 4, then air intake valve 10 was opened, and fed the air of low temperature in admission line 7, to reduce the temperature of flue gas; If air intake valve 10 is opened 5-10 after second, the measured temperature of temperature measurer II10 still is higher than the heat resisting temperature of filter bag 4, then opens vent valve 8, and with an overheated flue gas moment discharging part, the flue gas that is discharged enters in the standby dedusting pond 14 and carries out smoke abatement and dust control; After the measured temperature of temperature measurer II10 is lower than the heat resisting temperature of filter bag, close air intake valve 10, thereby overheated flue gas is not entered in the body 1 of sack cleaner, guaranteed the service life of filter bag 4.Flue gas enters in the filter chamber by deflector 13, and larger particles and unburnt grey star all directly clash into venetian blind type deflector 13 and fall in the ash bucket 5 in the flue gas, and flue gas is filtered by filter bag 4.When the collection ash of filter bag 4 outer surfaces reached the resistance of setting, switch board 15 started spraying and blowing organs 2 operation of jetting, and will collect ash and blow off in ash bucket 5; Pure air is after filtering discharged by air-introduced machine 3.When the dust accumulation in the ash bucket 5 to need carry out deashing the time, then open spray head 6, thereby produce reentrainment of dust when avoiding the deashing operation.
