Description
Technical field
What the utility model related to a kind of waste asphalt particle dug for the treatment of old road facing cut utilizes equipment again, is specifically related to a kind ofly be applicable to the recycling system that bituminous mixture dries heating.
Background technology
Pitch hot-mix plant recycling equipment after milling, transports old asphalt pavement back batching plant, Convergency fracturing, and according to the quality of road surface different structure level and specifications and models requirement, carry out proportion design, Bituminous concrete surface particle (reworked material) is heated to 160 degree to 200 degree, is incorporated in primary bituminous mixture (primary material) with the ratio being generally no more than 50%, in a mixing bowl, heats the compound of mix Cheng Xin, obtain excellent Recycled Asphalt Pavement, making becomes reclaimed bituminous pavement.Before adding thermal agitation, reworked material and primary material all need to carry out continuing to dry heating, temperature keeping, and the hot gas produced after being burnt by heater provides required heat.Owing to easily producing the tail gas of temperature more than band imperfect combustion in a large number when heater burns, tail gas reworked material after reworked material cartridge heater also can produce waste gas again, the tail gas of these heat burns although out also can reenter reworked material heater through hot gas cycle pipeline afterwards again from Drying gas outlet, eliminate pernicious gas, recycle heat, but because the tail gas amount of the heat in Drying is larger, partial tail gas is still had to discharge, if not treated, belong to discharge in violation of rules and regulations, increase atmosphere pollution, as process, just need to set up environmental protection facility, increase cost of production.Meanwhile, the waste heat of hot gas is directly discharged, and also can cause heat pollution to air, resource wastes, and is unfavorable for energy-saving and emission-reduction.
Summary of the invention
For above-mentioned defect, the utility model provide a kind of can by burner produce excessive using waste heat from tail gas carry out recycling, be conducive to environmental protection and resource-effective be applicable to bituminous mixture dry heating recycling system.
The utility model is achieved through the following technical solutions: a kind of bituminous mixture that is applicable to dries the recycling system heated, comprise reworked material Drying and primary material Drying, the air inlet port of two Dryings is communicated with primary material burner with reworked material burner respectively by air inlet pipe, heating source is provided to the reworked material in Drying and primary material, the gas outlet of described reworked material Drying is connected to hot gas cycle pipe and tail gas recycling pipe, the air inlet port of hot gas cycle pipe access reworked material burner, tail gas recycling pipe accesses the air inlet port of primary material burner, logical closing is implemented by adjustable damper between described hot gas cycle pipe and tail gas recycling pipe.
The technical scheme that the utility model improves further is: be also provided with flow meter and automatic controller between described hot hot gas cycle pipe and tail gas recycling pipe, the flow signal of automatic controller reception flow meter is gone forward side by side to take action and is done, the air intake flow of regulation and control adjustable damper.
The technical scheme that the utility model further improves is: the gas outlet of described primary material burner is connected to sack cleaner, and the lower outlet of sack cleaner is connected to mineral fine recovering device.
The hot gas cycle pipe that the utility model is connected to by the gas outlet of reworked material Drying and tail gas recycling pipe, not only the tail gas of heat is introduced reworked material Drying air inlet port, simultaneously, again the tail gas of excessive heat is accessed the air inlet port of primary material burner, waste heat in recycling tail gas, second-time burning is carried out to tail gas simultaneously, reduce the generation of pernicious gas, reduce exhaust emission.The flow meter of hot gas cycle pipe and the setting of automatic controller, can realize automation mechanized operation, carries out intellectuality and distribute, regulate air door according to temperature and flow.Breeze in tail gas after sack cleaner process can reclaim by breeze recover, economizes on resources further, reduces cost of production, reduces the environment pollution that dust causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the air inlet port of reworked material Drying 3 of the present utility model is communicated with reworked material burner 1 by air inlet pipe 2, the reworked material in the heat oven dry produced with burner 1 burning by reworked material, heating, insulation reworked material Drying 3.The gas outlet of described reworked material Drying 3 is connected to hot gas cycle pipe 4 and tail gas recycling pipe 5, and hot gas cycle pipe 4 accesses the air inlet port of reworked material burner 1, and tail gas recycling pipe 5 accesses the air inlet port of primary material burner 9.Adjustable damper 6, flow meter 8 and automatic controller 7 is provided with between described hot gas cycle pipe 4 and tail gas recycling pipe 5, the flow signal that automatic controller 7 receives flow meter 8 action of going forward side by side is done, auto-control is implemented to adjustable damper 6, realize tail gas logical between hot gas cycle pipe 4 and tail gas recycling pipe 5 close and tail gas by the size of flow.The tail gas of excessive heat is accessed the air inlet port of primary material burner, the waste heat in recycling tail gas, carries out second-time burning to waste gas simultaneously, reduces the generation of pernicious gas, reduces exhaust emission.
Still as shown in Figure 1, the air inlet port of primary material Drying 11 is communicated with primary material burner 9 by air inlet pipe 10, and being burnt by primary material burner 9, the heat produced is dried, heated, the primary material be incubated in primary material Drying 11.The gas outlet of described primary material Drying 11 is communicated with escape pipe 12, and escape pipe 12 accesses sack cleaner 13 again, and sack cleaner 13 times outlets are connected to mineral fine recovering device 14.Under the gravitation of dedusting air-introduced machine, tail gas in primary material Drying 11 enters sack cleaner 13 and carries out dedusting, the breeze produced carries out recycling recycling through mineral fine recovering device 14, tail gas is discharged from discharge pipe 15, economize on resources further, reduce cost of production, reduce the environment pollution that dust causes.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
