Background technique
Hot-blast stove starts to be widely applied in late 1970s as the hot-blast stove of thermal power machinery in China, in many
Industry has become the regeneration product of electric heat source and conventional vapor power heat source, mostly uses coal, coke, diesel oil, heavy oil, coal gas etc.
As fuel, but a series of pernicious gas can be generated after above-mentioned fuel combustion, environment and human body are caused very serious
It influences.
With the development and progress of society, people increasingly pay attention to environment, and traditional hot-blast stove is gradually by biomass
Hot-blast stove is substituted, and so-called biomass thermal wind furnace is exactly using biomass as fuel, and the pernicious gas of generation is few compared with traditional fuel.
But since biomass generally has the characteristics that moisture content is high, fuel change in size is big and content of ashes is high, cause biomass thermal
Wind furnace distribution wind unfair is even, fuel combustion is incomplete, the thermal efficiency is low, smoke abatement and dust control is poor, discharge not environmentally the defects of.It can be seen that
The appearance of biomass thermal wind furnace still without very good solution environmental pollution the problem of, then how to overcome above-mentioned technical problem,
Studying a kind of environmentally friendly biomass thermal wind furnace becomes current technical problem urgently to be solved.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of biomass thermal wind furnace, fuel combustion sufficiently, nothing
Tar, high combustion efficiency, thermal conversion rate is high, and internal-combustion is completely independent with external hot-air system, is used for a long time pollution-free, smoke elimination
Good dedusting effect.
In order to solve the above technical problems, the technical solution of the present invention is as follows:
A kind of biomass thermal wind furnace, comprising: hot wind furnace body, combustion chamber, inlet air plenum, go out air compartment, air blower at ash accumulating chamber, described
Combustion chamber is divided into the first combustion chamber, the second combustion chamber, and first combustion chamber connects first charging aperture, and second combustion chamber connects
Second charging aperture is connect, ash accumulating chamber is equipped with below second combustion chamber, the ash accumulating chamber bottom is equipped with ash discharging hole, the inlet air plenum
The air blower of the hot-blast stove body exterior is connected, is equipped with air compartment above the inlet air plenum, outlet air ceiling portion is equipped with heat
Wind outlet；The first fire grate, second combustion chamber and the product are equipped between first combustion chamber and second combustion chamber
The second fire grate between grey room.
Hot wind furnace body periphery is made of heat-insulating heat-preserving material.
First fire grate is vibrating-grate stoker.
Respectively there is an air outlet in the top of first combustion chamber and second combustion chamber, respectively with inlet air plenum, go out air compartment
It communicates.
There is one layer of alumina firebrick between the inlet air plenum and the air compartment out, there are several logical on the alumina firebrick
Air holes.
A dust-extraction unit is equipped at the hot-blast outlet.
The invention has the benefit that 1) use second-time burning mode, burn sufficiently efficient, no tar, high combustion efficiency,
Thermal conversion rate is high, and internal-combustion is completely independent with external hot-air system, is used for a long time pollution-free, reduction environmental pollution；2) flue dust
By the dust-extraction unit that hot-blast outlet is arranged, so that flue dust achieves that discharge reaches ring without black smoke, without auxiliary equipment processing
Guarantor's standard；3) rationally, structure is simple, and manufacturing cost is low, and heating surface area is big for design, and the thermal efficiency is high, uses simple and fast maintenance rate
It is low.
