Description
Technical field
The present invention relates to the recovery profit of a kind of retracting device and recovery method, more particularly to a kind of organic solid waste pyrolysis off-gas
Use device and method.
Background technology
The harmful solid waste of China year yield at 15,000,000 tons or so, harmful solid waste can penetrate into soil in soil after weathering
Earth, destroys the corrosion capacity of decomposition of soil；The solid waste of long-term outdoor placement can be volatilized substantial amounts of waste gas and dust, and air is caused
Severe contamination etc., solid waste pollution problem has caused the attention of society.
The processing to chemical solid waste mainly uses the mode such as landfill, biological treatment after burning at present.Burning process lack
On the one hand point is that cost is high, and flying dust (harmful components containing dioxin), the stench on the other hand produced therewith also brings along secondary dirt
Dye.China is in the stage of urbanization rate fast lifting, and urban land has been scarce resource, and filling needs large area
Secondary pollution problem after soil, landfill is also very serious.
Pyrolytic technique is a kind of organic solid waste treatment technology of novel environment friendly, using widely, but is produced after solid waste pyrolysis
Raw fuel gas air pressure is extremely unstable, it is difficult to recycle, and existing method is to be vented waste gas to burn, and both pollutes environment,
Heat energy is wasted again.
The content of the invention
Environment is polluted to the exhaust-gas treatment of generation to solve existing current organic solid waste Non-oxygen pyrolytic apparatus, heat energy is wasted
Shortcoming, the invention provides one kind it is simple in construction, be easy to promote, use cost it is low, it is environmentally friendly and do not cause thermal waste
Organic solid waste pyrolysis off-gas retracting device, and there is provided a set of corresponding recoverying and utilizing method.
The present invention concrete technical scheme be：
A kind of organic solid waste pyrolysis off-gas recycling system, it is characterised in that：Including back-fire arrangement, gas flare,
Waste gas burning room, flue gas heat exchanger, smoke duster；The air inlet of the back-fire arrangement is connected to three-phase separating system, row
Gas port is connected to gas flare, and the gas flare is connected to waste gas burning room；Handed over flue gas heat the waste gas burning room
Parallel operation is connected, and the flue gas heat exchanger is connected with smoke duster.
Accordingly, a kind of organic solid waste pyrolysis off-gas recoverying and utilizing method, it is characterised in that comprise the following steps：It is organic solid
By three-phase separating system after used heat solution, uncondensable fuel gas is isolated, fuel gas passes through back-fire arrangement, and control is not
Stable combustible gas air pressure；Combustible gas is burned by gas flare into waste gas burning room, the high-temperature flue gas warp after burning
Cross flue gas heat-exchange system and give system heat supply, dry thermal source as organic solid waste, the flue gas after heat exchange passes through smoke duster
Discharged after processing is up to standard.
The technical scheme that the present invention is provided has compared with much progress compared with for prior art, is mainly reflected in：Use cost is low,
It is easy to promote, not welding and the saving energy.
Brief description of the drawings
Fig. 1 is a kind of structural representation for organic solid waste pyrolysis off-gas recycle device that the present invention is provided
Identified in figure：
1. back-fire arrangement；2. gas flare；3. waste gas burning room；4. flue gas heat exchanger；5. smoke duster.
Embodiment
Below in conjunction with drawings and Examples to a kind of disclosed organic solid waste pyrolysis off-gas recycle device
And method is further explained.
A kind of organic solid waste pyrolysis off-gas recycle device as shown in Figure 1, including back-fire arrangement 1, gas flare
2nd, waste gas burning room 3, flue gas heat exchanger 4, smoke duster 5；The air inlet of the back-fire arrangement 1 is connected to three phase separation system
System, exhaust outlet are connected to gas flare 2, and the gas flare 2 is connected to waste gas burning room 3；The waste gas burning room 3 with
Flue gas heat exchanger 4 is connected, and the flue gas heat exchanger 4 is connected with smoke duster 5.
Correspondingly, a kind of organic solid waste pyrolysis off-gas recoverying and utilizing method that the present invention is provided comprises the following steps：
By three-phase separating system after organic solid waste pyrolysis, uncondensable fuel gas is isolated, fuel gas passes through
Back-fire arrangement 1, controls unstable combustible gas air pressure.Combustible gas is entered into waste gas burning room 3 by gas flare 2 to burn,
High-temperature flue gas after burning gives system heat supply by flue gas heat-exchange system 4, and thermal source, the cigarette of heat exchange are dried as organic solid waste
Gas by smoke duster 5 handle it is up to standard after discharge.
The major advantage of organic solid waste pyrolysis off-gas recycle device provided by the present invention and method is：
Because it is extremely unstable to isolate fuel gas air pressure, it is difficult to which recovery is used, waste gas is vented by former technique to burn, so
Waste gas burning pollutes environment, and heat is wasted again.The system makes unstable pyrolysis gas be system heat supply by burning disposal
Relatively stable heat is provided, use cost is low, be easy to promote, not welding and the saving energy.
Above example is the explanation of the embodiment to the present invention, rather than limitation of the present invention, relevant technology
The technical staff in field without departing from the spirit and scope of the present invention, can also make various conversion and change and obtain
To corresponding equivalent technical scheme, therefore all equivalent technical schemes should be included into the patent protection model of the present invention
Enclose.
