Description
Technical Field
The utility model relates to a dust collecting equipment technical field, concretely relates to simple and easy tail gas dust collector.
Background
At present, with the tightening of environmental protection policy, the emission index of harmful impurities in the discharged tail gas is lower and lower, especially for nitrogen oxides, sulfur dioxide, dust and the like, and for industries such as heavy industry, chemical industry, energy, electric power and the like, the pressure of flue gas treatment is further strengthened. In the metallurgical industry, the dust content in the discharged flue gas is controlled to be 10mg/m in some areas 3 The dust removal is under great pressure, the dust removal modes commonly used at the present stage are gravity dust removal, cloth bag dust removal and the like, the dust removal effect is poor, and the specified dust removal index is difficult to achieve when the fluctuation of smoke components is large, so that the establishment of pre-dust removal of smoke is crucial to the environmental protection for initially reducing the dust content. Therefore, the simple tail gas dust removal device is urgently needed to be designed to solve the problems that the existing flue gas dust removal equipment is poor in dust removal effect on fluctuant flue gas and the emission does not reach the standard.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide a simple and easy tail gas dust collector.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a simple and easy tail gas dust collector, includes deposit room and dust removal net, the deposit room includes first deposit room and second deposit room, and the volume of second deposit room is greater than first deposit room, and the discharge port of flue gas is connected through the air inlet that is equipped with to first deposit room for the two-stage of flue gas is subsided and is removed dust, and the dust removal net is installed in the exit of second deposit room, is used for the entrapment fine particle dust.
Specifically, ash deposition hoppers are arranged below the first settling chamber and the second settling chamber, discharge openings are formed in the bottoms of the ash deposition hoppers, and ash discharge valves are mounted on the discharge openings and used for discharging particulate matters.
Specifically, a back flushing valve is arranged behind the dust removing net and is an electric valve, the electric valve is connected with a controller, a time relay is arranged in the controller, the time relay controls the back flushing valve to be indirectly opened to eject high-pressure gas, and fine particle dust on the dust removing net is blown down into the dust collecting hopper.
Specifically, an exhaust port is arranged on the second settling chamber and at the rear part of the dust removal net and used for exhausting filtered flue gas, and a fan is arranged on the exhaust port and used for assisting in flue gas emission.
The utility model discloses following beneficial effect has:
the utility model discloses a simple and easy tail gas dust collector dust-laden tail gas loops through first settling chamber and second settling chamber after entering from the air inlet, because its volume is great, air velocity reduces to some extent, and the particulate matter can subside in the deposition bucket of below, and remaining gas passes through the dust removal net and tentatively catches, gets into the deposition bucket of below under the effect of blowback valve, and clean gas is discharged from the gas vent; simple tail gas pre-dedusting equipment with simple equipment, good pre-dedusting effect and low operation cost.
Drawings
Fig. 1 is a schematic structural diagram of a simple tail gas dust removal device.
In the figure: 1-an air inlet; 2-a first settling chamber; 3-a second settling chamber; 4-dust removal net; 5-an ash discharge valve; 6-ash deposition bucket; 7-a blowback valve; 8, a fan; 9-exhaust port.
Detailed Description
The technical solution in the embodiments of the present invention will be described in further detail in the following clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figure 1, the simple tail gas pre-dedusting device has the advantages that the space of the dust-containing tail gas entering from the gas inlet 1 reaches the first settling chamber 2, the tail gas speed is reduced, large-particle dust falls into the dust collecting hopper 6 under the action of gravity, the rest tail gas continues to enter the second settling chamber 3, the volume of the second settling chamber 3 is larger than that of the first settling chamber 2, the tail gas speed is further reduced, and fine-particle dust falls into the dust collecting hopper 6 at the lower part under the action of gravity again.
There is dust removal net 4 at second settling chamber 3 end for the entrapment fine particle dust, blowback valve 7 is the motorised valve, motorised valve connection director, be equipped with time relay in the controller, the jet out high-pressure gas is opened to time relay control blowback valve 7's indirectness, can blow off fine particle dust on the dust removal net 4 and then enter into deposition bucket 6, fan 8 is located gas vent 9, a speed for providing gas motion, the tail gas after the processing is discharged from gas vent 9, the particulate matter is discharged through unloading valve 5.
Dust-containing tail gas enters from the gas inlet 1 and then sequentially passes through the first settling chamber 2 and the second settling chamber 3, the gas flow speed is reduced due to the large volume of the tail gas, particulate matters are settled into the dust collecting hopper 6 below, the rest gas is preliminarily collected after passing through the dust removing net 4 and enters the dust collecting hopper 6 below under the action of the back flushing valve 7, and clean gas is discharged from the gas outlet 9; simple tail gas pre-dedusting equipment with simple equipment, good pre-dedusting effect and low operation cost.
