Description
Technical field
This utility model provides a kind of biomass material drying unit, belongs to drying plant technical field.
Background technology
China is large agricultural country, and stalk resource enriches, and is only easy to the agricultural crop straw collected, and annual production has reached more than 600,000,000 ton the most.The processing mode of agricultural crop straw is and burns in field.Not only produce substantial amounts of exhaust emission environment when burning, waste resource simultaneously.At present, being directed to makes rational use of resources have developed straw is made biomass molding fuel.Stalk can be carried out drying and processing before straw is compressed molding, can produce tail gas in drying course, containing combustibles such as a large amount of tar in tail gas, existing drying plant is all directly to be emptied by tail gas, causes environmental pollution.It addition, existing drying plant operationally can produce substantial amounts of airborne dust, one is to cause bigger loss of material；Two is that airborne dust mostly is combustible, as easy as rolling off a log when high temperature is dried catches fire, and causes serious consequence.
Utility model content
For solving the problems referred to above, this utility model provides a kind of biomass material drying unit, the specific scheme is that
A kind of biomass material drying unit, including conveyer, drying chamber, combustor, waste heat boiler and air-introduced machine, the conveyer belt of described conveyer is positioned at drying chamber, and conveyer belt is provided above at least one row's rake feeding mechanism, and rake feeding mechanism is provided above Air Filter；The afterbody of drying chamber is connected to combustor by offgas duct, and described offgas duct is provided with cyclone separator, above the conveyer belt that the discharging opening of cyclone separator is connected in drying chamber；Combustor is connected to waste heat boiler by flue, and the steam pipe of waste heat boiler is connected to inside drying chamber, and connects with the row's steam jet being arranged in drying chamber；The flue of waste heat boiler is connected to air-introduced machine, air-introduced machine outlet and ft connection；Described combustor is provided with air heating pipe, and air heating pipe passes through air inlet and ft connection, and is connected with the head of drying chamber by pipeline；The head of drying chamber is consistent with the feed end of conveyer；Described drying chamber and combustor are refractory material laying, and are provided with heat-insulation layer.
Further, described Air Filter is finer wire net.
Further, the air inlet of described air heating pipe is provided with air filter.
Further, described combustor is provided with thermocouple.
Further, described air-introduced machine is frequency conversion fan.
Useful point of the present utility model is: the tail gas produced in drying chamber is incorporated into combustor by this programme, the combustibles such as most tar in tail gas are fully burnt in combustor, both tail gas can have been avoided directly to empty the environmental pollution caused, can simultaneously serve as supplementing fuel, heating is arranged on the air heating pipe of combustor, is heated to form hot-air by the air of air heating pipe, in being incorporated into drying chamber dries the raw material on conveyer belt, fuel can be saved, reduce cost；Drying chamber and combustor use refractory material laying, and flameproof effect is good, and service life is long；Conveyer belt is arranged over Air Filter, can alleviate airborne dust；Steam jet in combustor can spray a large amount of steam when catching fire, and puts out a fire in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
