Abstract
The utility model discloses a tail gas treatment device of a used bituminous mixture regenerative equipment of the road construction technology field, which comprises a smoke box positioned on the regeneration dry roller tail section, an induced draft pipe is connected on a smoke box outlet, wherein the outlet of the induced draft pipe is connected with a induced draft fan, the outlet of the induced draft fan is connected with an air door adjusting valve, the outlet of the air door adjusting valve is connected with a strong mixing induced draft pipe and a regeneration induced draft pipe, the outlet ends of the strong mixing induced draft pipe and the regeneration induced draft pipe are respectively connected with a front smoke box gas cavity of a matched strong mixing dry roller and a fire-leading vent the gas cavity of a regeneration dry roller. Compared with the prior art, the tail gas can be burnt once more, the residual heat in the tail gas is fully utilized, the tail gas emission can be achieved the requirement of the environmental protection, and a cloth bag dust remover is not damaged.
Description
Technical field
The utility model belongs to the road construction work technical field, is a kind of exhaust gas processing device of waste asphalt mixture reclaim equiment of supporting pressure batch asphalt mixing plant use.
Background technology
The waste asphalt mixture reclaim equiment is that the block asphalt after the fragmentation is heated, stirs, makes it to form single pellet, is transported in the pressure batch asphalt mixing plant that matches with it again and mixes stir process.Existing waste asphalt mixture reclaim equiment exhaust gas processing device is that tail gas is directly introduced by induced duct before the primary dust removing equipment of forcing batch asphalt mixing plant, by the dust pelletizing system of forcing batch asphalt mixing plant tail gas is discharged.Owing in the tail gas that the waste asphalt mixture reclaim equiment is discharged, a large amount of waste heats are arranged, directly discharging causes the waste of heat, owing to also contain pernicious gas, imflammable gas and pitch smog in the tail gas, therefore above-mentioned exhaust gas processing device easily causes dust-removal cloth-bag bonding and pitch smoke pollution of environment, do not meet environmental requirement, even can cause the burning of sack cleaner cloth bag.
Summary of the invention
The utility model purpose provides a kind of tail gas to burn once more for solving the problems of the technologies described above, and makes full use of the waste heat in the tail gas, and exhaust emissions reaches environmental requirement and do not damage the exhaust gas processing device of the waste asphalt mixture reclaim equiment of sack cleaner.
For achieving the above object, the technical solution adopted in the utility model is improved on the basis of existing waste asphalt mixture reclaim equiment exhaust gas processing device, with pipeline that regeneration drying drum afterbody smoke box is connected on set up air-introduced machine, the outlet of air-introduced machine connects the air door control valve, the outlet of air door control valve connects simultaneously mixes induced duct and regeneration induced duct by force, and the port of export of mixing induced duct and regeneration induced duct by force is connected the supporting implication chamber of igniting of mixing the front smoke box air cavity and the regeneration drying drum of drying drum by force respectively.
Adopt the beneficial effect of technique scheme: will the regenerate tail gas of drying drum of the air-introduced machine of this waste asphalt mixture reclaim equiment exhaust gas processing device is drawn, process air door control valve is assigned to the regeneration drying drum with it and mixes by force and carry out second-time burning in the drying drum, make and also contain pernicious gas in the tail gas, imflammable gas and pitch smog burn, reach the discharge standard of environmental requirement, pernicious gas bonding cloth bag and air-polluting problem have been solved, avoided the imflammable gas scaling loss sack cleaner in the tail gas, make full use of the waste heat in the tail gas simultaneously, saved fuel energy.
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the exhaust gas processing device of waste asphalt mixture reclaim equiment.
Fig. 2 is the exhaust gas processing device assembling back schematic diagram of waste asphalt mixture reclaim equiment.
The specific embodiment
The exhaust gas processing device of waste asphalt mixture reclaim equiment as shown in Figure 1, 2 has the smoke box 1 that is positioned at regeneration drying drum 8 afterbodys, air-introduced machine 2, air door control valve 4, mixes bleed airduct and regeneration bleed airduct by force.The outlet of smoke box 1 is connected with induced duct 7, one end of induced duct 7 connects air-introduced machine 2, air-introduced machine 2 is driven by motor 3, the outlet of air-introduced machine 2 connects air door control valve 4,4 outlets of air door control valve connect simultaneously mixes induced duct 6 and regeneration bleed airduct 5 by force, and the port of export of mixing induced duct 6 and regeneration induced duct 5 by force is connected the supporting implication chamber 9 of igniting of mixing the front smoke box air cavity 10 and the regeneration drying drum of drying drum 11 by force respectively.
Operation principle of the present utility model is: coal-fired combusting device is to entering the waste asphalt mixture heating in the regeneration cylinder, the air-introduced machine of the harmful pitch smog that produces by reclaim equiment is sent to respectively in the air chamber 10 of ignite implication chamber 9 and the supporting drying drum of mixing by force 11 front smoke boxs of regeneration drying drum 8, thereby carry out second-time burning, tail gas after the burning is handled the back discharging by supporting air inducing dust pelletizing system of mixing by force, thereby solves pernicious gas bonding cloth bag and air-polluting problem.
Claims (1)
1. the exhaust gas processing device of a waste asphalt mixture reclaim equiment, has the smoke box that is positioned at regeneration drying drum afterbody, the smoke box outlet is connected with induced duct, it is characterized in that: the outlet of described induced duct connects air-introduced machine, the outlet of air-introduced machine connects the air door control valve, the outlet of air door control valve connects simultaneously mixes induced duct and regeneration induced duct by force, and the port of export of mixing induced duct and regeneration induced duct by force is connected the supporting implication chamber of igniting of mixing the front smoke box air cavity and the regeneration drying drum of drying drum by force respectively.
