Description
Technical field
The utility model is related to a kind of equipment dried to grain by utilization biomass energy, specifically a kind of biomass
Energy all steel waste gas recovery energy-saving environment protection air heater.
Background technology
Even to this day, main energy sources of the China used in grain heat-drying field remain the traditional energies such as fossil fuel,
Data display according to the relevent statistics, China need to dry 90,000,000 tons of grain every year, and with 10% annual growth, from combustion at present
Material service condition is seen, most of to carry out grain heat-drying, particularly four province of northeast and northwest ground using the coal of less expensive
Area, year consume about 4,500,000 tons of coal, consume about 700,000,000 degree of electric energy, produce about 10,000,000 tons of carbon dioxide, and total drying expense is about
4000000000 yuan, as most of investor there are the acts and efforts for expediency of the fast income of few input, cause that technique is simple and crude, technical equipment falls behind,
Cause energy waste serious, discharge not up to standard, environmental pollution is serious.
China's grain gross annual output amount reaches more than 600,000,000 tons in recent years, and the stalk total amount that can be used as fuel is more than 300,000,000
Ton, if stalk to be all processed into shaped fuel（Calorific value per ton is by 3500 kilocalories/kilogram calculating）, mark equivalent to 1.5 hundred million tons
Quasi- coal（7000 kilocalories/kilogram）.There is very high utilization as the accessory substance produced in agricultural product production process in agricultural crop straw
According to relevant research, value, shows that the use value of four tons of stalks is eaten equivalent to a ton-grain, is genuine second half agriculture
Industry, but within the very long one section period of human historical development, due to lacking related technology and understanding, also due to petrochemical industry in the past
Fuel price is relatively cheap, is up to the present less than 43% to stalk comprehensive utilization rate, and rural area has more than the straw of more than half part
Stalk is not all utilized, and the stalk for failing to utilize has changed into ecological rubbish, needs to spend manpower to carry out stalk in field
Simple burning disposal, had not only polluted environment but also waste of resource.

Throw away or burn.
Next to that technical problem.As un-compressed stalk caloric value is low, containing a large amount of ash contents, in combustion can
Coking phenomenon is produced, up to this point, domestic biomass thermal wind furnace also can't resolve this difficult problem, therefore, straw utilization
It is a relatively difficult problem.
Currently, due to the biomass combustion device for not having technology maturation, particularly in grain heat-drying field, state's endogenous substance
Hot-blast stove is substantially blank out, due in grain heat-drying, as grain heat-drying is all to carry out in the winter time mostly, biomass
Hot-blast stove adopts water cooling and does not apply to, and is technically acquired a certain degree of difficulty using air-cooled, therefore, current domestic biomass hot air
Stove be substantially exactly using coal-fired hot-blast stove firing biomass fuel, due to biomass fuel compared with coal in combustion characteristics
There is bigger difference, so and not applying to.
The shortcoming of existing biomass thermal wind furnace and the problem for existing：Existing biomass thermal wind furnace is in original coal hot-air
Transform on furnace foundation, using with chain fire-gate traditional masonry construction, volume is big, floor space is big, radiation loss is big；Not yet
Have surplus heat recycling system, and thermal loss is big, and the hot blast efficiency of furnace is low；Due to being transformed on the basis of fire coal, its structure is simultaneously
Be not suitable for firing biomass fuel, be heated in body of heater and uneven, the easy season cracking of refractory material in burner hearth, life-span are low, heat
Wind furnace efficiency is very low；Further need exist for configuring hot blast stove air blast, coaling machine and slag remover, equipment investment is big, safeguard and keep in repair
High cost, power consumption are big, and also need to the basic constructional design of complexity and strict foundation construction, construction investment expense
Greatly.
