Description
Technical field
The utility model relates to a kind of bag filters, more particularly to one kind is for handling asphalt mixing plant tail
The bag filter of gas.
Background technique
Asphalt mixing plant includes roller drying device, and roller drying device is used for asphalt-regenerating material or aggregate
It is dried, a large amount of tail gas with dust and heat can be generated at work, need to carry out at tail gas using bag filter
Reason.
The bag filter of asphalt mixing plant is divided into atmosphere back flushing type and arteries and veins according to purge mode is unusual
Rush back flushing type.Atmosphere back flushing type working principle is that cloth bag surface has accumulated many dusts in the deduster course of work, at this point,
Cylinder drives the blowback door of the lower one of gas chamber of opening deduster, keeps this plenum roof and air-introduced machine inlet pipeline disconnected
It opens, while communicates the top of a gas chamber with normal pressure atmosphere.It is negative due to being constantly under air-introduced machine effect inside deduster
Pressure condition, outside air can enter inside deduster under this suction function from the top blowback door of this gas chamber.This
Process to produce reverse flow by the air-flow side of cloth bag in this gas chamber.Back draught will be adhered on cloth bag outer wall
The dust in face, which is blown off, to be got off to realize the deashing of cloth bag.
Such purge mode back blow port during blowback has sucked a large amount of room temperature cold air.These room temperature cold air meetings
The environment temperature inside deduster is reduced, with the reduction of temperature, the vapor in exhaust gas can condense into liquid water and be adhered to cloth
Bag surface causes to make moist or be adhered to cloth bag surface in the dust for not representing face simultaneously.In order to solve this problem, general operation
Mode is exactly to properly increase the temperature of roller tail gas, makes its temperature after by the cooling of blowback cold air that can also be higher than 80 DEG C.But
The exhaust temperature for improving roller means that the energy consumption for increasing equipment, while increasing the amount of exhaust gas.
Summary of the invention

Further, the pure room have connection air-inducing passage the first communication port and be connected to blowback room second be connected to
Mouthful, the control valve includes the cylinder that sealing plate and driving sealing plate close the first communication port or the second communication port.
Further, the blowback room is laterally extended arrangement, and multiple pure rooms are along blowback room arranged.
A kind of roller drying device, for being dried to asphalt-regenerating material or aggregate, it is characterised in that：Including described
Atmosphere backblown cloth-bag dust collector.
A kind of dust removal method of atmosphere backblown cloth-bag dust collector, it is characterised in that：Include the following steps：
When not opening blowing function, all pure rooms are connected to air-inducing passage, and air-introduced machine guides the tail gas in exhaust gas chamber by cloth
Bag filters and enters pure room, then is discharged from pure room；
When needing the cloth bag to certain pure room to carry out blowback cleaning dust, control valve controls the pure room connection blowback
Room, and other pure room connection air-inducing passages continue filtration；
Back blowing machine guides air to enter blowback room after over-heat-exchanger, and air carries out heat through over-heat-exchanger and tail gas
Exchange makes air have certain heat, and hot-air enters pure room from blowback room and carries out blowback to cloth bag, will be adhered to cloth bag
On dust blow off, after completing blowback, control valve controls pure room connection air-inducing passage and restores filtration.
A kind of atmosphere backblown cloth-bag dust collector, including exhaust gas chamber, air-introduced machine, multiple pure rooms, setting are each pure
Cloth bag between room and exhaust gas chamber, pure room are connect by air-inducing passage with air-introduced machine input port, it is characterised in that：It further include anti-
Room, heating device, back blowing machine and control valve are blown, control valve is for controlling pure room connection blowback room or air-inducing passage, blowback
For guiding air to enter blowback room, heating device is used to heat the air into blowback room blower.
The utility model has the advantages that：
When work, normal temperature air is inhaled into heat exchanger under the action of back blowing machine, the high temperature being located in chimney
Tail gas heating.Hot-air after heating is sent into bag filter blowback channel under the action of back blowing machine and is carried out to cloth bag
Blowback.It is at this time the high-temperature hot air for having wind pressure for the air of blowback, such hot-air facilitates the raising of blowback effect, together
When not will lead to the reduction of deduster internal temperature, reduce in exhaust gas the case where moisture condenses.
Back blowing machine import is connected with heat exchanger outlet, and it can be blowback that outlet is connect with the blowback channel of deduster
Channel provides the high temperature air of certain positive pressure.
Heat exchanger is mounted on the outlet port of air-introduced machine, is minimized by the exhaust temperature after heat exchanger, tail gas
In partial moisture condense and be collected in a heat exchanger.The steam vapour amount emitted in chimney is reduced.
If applying technique, the temperature for the exhaust gas that the exhaust temperature of roller can be reduced, while is discharged in chimney is obtained
To reduce, the liquid water condensed in partial tail gas while waste-gas heat discharge is reduced.
