Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is that inertia adsorbs deduster internal structural map；
In figure: burner 1, hot-blast stove 2 regenerate roller 3, air inducing pipeline 4, and inertia adsorbs deduster 5, air distribution blower 6, aid distributing pipe
Road 7 administers blower 8, administers pipeline 9, fume treatment auxiliary 10, and partition 51 is adsorbed in labyrinth.
Specific embodiment
The present invention will be further explained combined with specific embodiments below.
It as shown in Figure 1 to Figure 2, is a kind of hot in-plant reclaimed heating system, including burner 1, hot-blast stove 2, regeneration roller
3, air inducing pipeline 4, inertia absorption deduster 5, air distribution blower 6, air distribution pipeline 7, improvement blower 8, improvement pipeline 9, fume treatment
Equipment 10 etc..
1 front end of burner is deep into inside hot-blast stove 2, and hot-blast stove air outlet is connected with regeneration 3 air inlet of roller, hot-blast stove
2 length are longer than the length of flame, can prevent flame from entering regeneration drums inside and directly contact with asphalt reclamation material generation.
Also there are air distribution interfaces for hot-blast stove 2, for the exhaust gas of the bituminous blue smoke generated after heat exchange to be backed into hot-blast stove
Burning air distribution heat exchange is carried out, 500-600 DEG C of hot wind is ultimately formed.
4 one end of air inducing pipeline is connected with regeneration 3 air outlet of roller, and other end adsorbs 5 air inlet phase of deduster with inertia
Even.
It also includes 2 air outlets that inertia, which adsorbs deduster 5, is connected respectively with air distribution blower 6 and improvement blower 8, and inside is also
Partition 51 is adsorbed equipped with labyrinth.
Air distribution blower 6 uses frequency control, can be precisely controlled air distribution air quantity, and the air inlet and inertia of air distribution blower 6 are inhaled
One air outlet of attached deduster 5 is connected, and the air outlet of air distribution blower 6 is connected with air distribution pipeline 7, then backs into hot-blast stove.
The air inlet for administering blower 8 is connected with another air outlet of inertia absorption deduster 5, administers the outlet air of blower 8
Mouth is administered pipeline 9 and is connected with smoke gas treatment equipment 10, and residue has neither part nor lot in air distribution bituminous cigarette pernicious gas and sets through smoke gas treatment
After standby processing, qualified discharge.
By introducing hot-blast stove, by flame control inside hot-blast stove, avoid directly contacting with Bituminous concrete surface reclaimed materials, simultaneously
Pernicious gas containing pitch blue smoke is recycled, air distribution is participated in, system is used for exchanging air temperature reduction, then be aided with cigarette
Gas controlling device is realized and is optimized to entire heating process, not only improves pavement performance, but also reduce pollution, realizes truly
Efficient, energy-saving and environmental protection.
When formal production, ash-laden gas is regenerated the air outlet of roller 3 and enters air inducing pipeline 4, then by air inducing pipeline 4 into
Enter the air inlet to inertia absorption deduster 5, there is array labyrinth to adsorb partition 51, ash-laden gas inside inertia absorption deduster 5
When mobile to air outlet from air inlet, need to first pass around these labyrinths absorption partition 51, it is a large amount of due to containing in flue gas
Dust and tar-like substance, due to the effect of inertia, when adsorbing partition 51 via these labyrinths, can be adsorbed on labyrinth absorption every
On plate 51, dust and liquid phase substance are removed, only remaining pernicious gas, and then pernicious gas enters air distribution blower 6, air distribution
Blower 6 is frequency control, can be convenient control recovered flue gas amount, and the air distribution of adjusted mistake backs into hot-blast stove by air distribution pipeline 7
2, the high temperature that harmful components in dusty gas are burnt, while generated with fuel combustion by flame is generated when burner 1 burns
Gas mixing forms 500-600 DEG C of hot wind, is introduced into the air inlet of regeneration roller 3, into inside regeneration roller 3, with Bituminous concrete surface
Reclaimed materials exchanges heat, and in cycles, moves back and forth, forms a closed-loop control, the heat being not only effectively utilized in flue gas, but also
Hot blast temperature is substantially reduced, solves aging, the coking problem of Bituminous concrete surface reclaimed materials；
Simultaneously, the ash-laden gas for having neither part nor lot in air distribution is administered blower 8, improvement pipeline 9 enters smoke gas treatment equipment 10,
Series reaction is carried out in smoke gas treatment equipment 10 and is aided with adsorbent equipment, flue gas is effectively purified, and flue gas can be with after purification
Publication discharge.
Entire production process is joined the polluted gas containing glance coal for participating in being formed after heat exchange by introducing hot-blast stove
With air distribution, sufficiently join with the complete high-temperature gas of burner combustion with formation temperature is merged in 500-600 DEG C of hot wind, then again with old drip
Green reclaimed materials is heated, and substantially reduces ageing of asphalt, at the same by remaining dusty gas be introduced into dedicated fume treatment auxiliary into
Row Concetrated control can both improve the pavement performance of reworked material after improvement with qualified discharge, the present invention, and in turn avoid exhaust gas to original
The negative effect at raw station, realizes efficient, energy-saving and environmental protection truly.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
