Description
Technical field
This practical utility model is related to field of energy-saving technology, and in particular to the garbage fired boiler hot-air system of burning biogas.
Background technology
The biogas in country's refuse-burning plant, generally there is three kinds of processing modes at present：Torch directly lights discharge, biogas hair
Electricity, biogas introduces garbage burning boiler burning.Torch directly lights discharge, though biogas can be processed effectively, reduces odor pollution,
Cause the pollution of environment and the waste of the energy.All higher to biogas and equipment requirement using marsh gas power generation, biogas desulfurization rate must
Must reach more than 99%, then by dehumidifying, could be generated electricity into internal combustion engine after a series for the treatment of such as supercharging, equipment is more, it is costly and
And actual biogas desulfurization, dewatering efficiency is poor, and unit operation stability is low, and operation expense is high.Biogas introduces waste incineration pot
Stove burning compares first two, biogas is fully used, and cost of investment is relatively low, has obtained applying in a big way.
But in actual motion, when garbage burning boiler combustion position is unstable, it is possible to cause blowing out because breaking down, or even entirely
The stoppage in transit of electricity generation system, thus the uncertain loss for causing will be inestimable.For above-mentioned phenomenon, need to propose that one kind can make
Biogas is fully used, and whole electricity generation system, safe, the wide biogas profit of feasibility of independent operating can be isolated to again
Use scheme.
Utility model content
In order to solve the above problems, the utility model is adopted the following technical scheme that：
In utility model embodiment, the garbage fired boiler hot-air system of described burning biogas, it mainly includes kitchen rubbish
Rubbish anaerobic pond, garbage leachate anaerobic pond, methane holder, booster fan, biogas burner, biogas hot-air stove, steam air
Preheater, garbage fired boiler, air inlet pipeline, outlet pipe, warm-air pipe and flue.
The kitchen garbage anaerobic pond and garbage leachate anaerobic pond employ integral type digester top cover, the natural pond of generation
Gas is combined into the methane holder by air inlet pipeline, then is connected to biogas burner by outlet pipe.The biogas combustion
Burner is installed on biogas hot-air stove.The hot blast that hot-blast stove is produced is delivered to garbage fired boiler through warm-air pipe, used as garbage fired boiler
First air is used；The flue gas that hot-blast stove is produced is delivered to boiler export flue through flue.
2 tunnels of the outlet pipe point arrangement, is made up of branch road I, branch road II.Branch road I and branch road II are respectively arranged with supercharging
Blower fan, the booster fan the using and the reserved.2 tunnels of the warm-air pipe point arrangement, is made up of warm-air pipe I, warm-air pipe II.If biogas fires
Burn the heat for producing and hot blast during temperature, directly garbage fired boiler is delivered to by warm-air pipe I by cold air heating needed for enough；If
The heat that biogas combustion is produced can not by cold air heating to required temperature when, warm-air pipe II is by hot blast through steam type airheater two
Garbage fired boiler is delivered to again after secondary heating.
Dewatering outlet, spark arrester, ball valve are equipped with the air inlet pipeline and outlet pipe.Dewatering outlet is in discharge pipe
Biogas condensed water.
The beneficial effects of the utility model are as follows：
1. the garbage fired boiler hot-air system of burning biogas, can make biogas be fully used, and can be isolated to again whole
Electricity generation system, independent operating, its is safe, and feasibility is wide.
2. the thermal source of steam type airheater heating hot blast comes from extracted steam from turbine and garbage fired boiler saturated vapor, using natural pond
Hot blast after gas and hot air stove heat, can make steam type airheater without or steamed with extracted steam from turbine and garbage fired boiler saturation less
Vapour, so as to save steam consumption quantity, increases generated energy.
3. methane holder is housed in this system, voltage stabilizing is served, the effect of steady amount uses the operation of biogas burner
Gas balanced condition, combustion position is secure.
4. after biogas introduces Combustion of Hot Air Furnace, the flue gas after burning can be taken off into garbage fired boiler flue gas purification system
Sulphuring treatment, so as to realize qualified discharge, it is to avoid environmental pollution and greenhouse effects.
5. the garbage fired boiler hot-air system of burning biogas, employs a biogas outlet pipe with two biogas hot-air stoves
Two garbage fired boilers of correspondence, this heating primary air system can run simultaneously, or the using and the reserved, biogas is emptied combustion position basic
It is zero, so as to realize making full use of for resource.
6. the garbage fired boiler hot-air system of burning biogas is simple and reliable using equipment, and critical piece is ripe, maintenance cost
Low, operational efficiency is high, can be widely popularized.
