The biomass fuel airheater comprises an outer sleeve, an inner sleeve, a heat blocking plate, a helical blade, a feed port, a controller, a thermoswitch, an oxygen sensor, a temperature sensor, a material gate segment, an access door, thermal insulation materials, a smoke discharging pipe, a smoke dust purifier, a hot wind discharge flange, a helical material pusher, a motor, an igniter, a drive sprocket, a fan, a flame detector, a combustor, a secondary air inlet, an air heater and a burner housing. According to the biomass fuel airheater, a structure that the inner sleeve is matched with the outer sleeve is adopted, meanwhile the helical blade is mounted on the outer wall of the inner sleeve, the heat blocking plate is arranged on the inner wall of the inner sleeve, a heating area is greatly increased, and the heat exchange rate is improved; the thermoswitch, a photoelectric sensor, the flame detector and the oxygen sensor are adopted and are particularly added to an automatic control system formed by the oxygen sensor, so the automation level is integrally improved; and at the same time, the smoke dust purifier is adopted, clean combustion is achieved, smoke is eliminated, dust is removed, and the biomass fuel airheater has the advantages of being efficient and environment-friendly and is specially suitable for being used as heat energy for industrial production and resident life such as agricultural greenhouse cultivation and villas.

Description

A kind of biomass fuel hot air stove

Technical field

The utility model belongs to the industrial combustion technology, more precisely a kind of biomass fuel hot air stove.

Background technology

Biomass fuel is as a kind of new forms of energy, worldwide be widely used, biomass fuel is take agricultural wastes, forestry waste etc. as raw material, has the useless inexpensive advantage of profit, application around biomass fuel, corresponding combustion stove is developing, present combustion stove existence smoke evacuation, the worn-out end that thermal conversion rate is low, automaticity is low, along with environmental quality requirement is more and more higher, the discharge standard of fuel combustion is more and more stricter, must improve clean burning technology and flue gases purification, improve the calorific value level of fuel.

Summary of the invention

Given this, the purpose of this utility model is, the biomass fuel hot air stove of a kind of clean environment firendly and high heating value conversion ratio is provided.

the purpose of this utility model is achieved through the following technical solutions: a kind of biomass fuel hot air stove, by overcoat, inner sleeve, hot baffle, helical blade, charging aperture, controller, thermoswitch, oxygen sensor, temperature sensor, limit material flashboard, access door, insulation material, the smoke evacuation cylinder, fume purifier, the hot-blast outlet flange, screw feeder, motor, igniter, drive sprocket, blower fan, flame detector, the combustion chamber, secondary intake opening, air-heater, burner shell forms, wherein the overcoat upside arranges the hot-blast outlet flange, the overcoat downside arranges access door, the access door inwall pastes insulation material, during interior covering device overlaps outside, outer wall of inside race device helical blade, inner sleeve inner wall device hot baffle, overcoat is close to side device smoke evacuation cylinder, device fume purifier in the smoke evacuation cylinder, the burner shell top has charging aperture, the thermoswitch device is below charging aperture, limit material flashboard by the drive sprocket device below charging aperture, screw feeder is connected with motor by drive sprocket, igniter is fixed on the combustion chamber, the combustion chamber is connected with housing, device is in inner sleeve, blower fan is fixed on burner shell, control device is on burner shell, oxygen sensor device is in overcoat, temp sensor device is in inner sleeve, flame detector is fixed on sidewall of combustion chamber, top, combustion chamber has the secondary blast hole, the air-heater device is in jacket bottom, be communicated with inner sleeve.

The automatic control system that wherein said controller is comprised of thermoswitch, temperature sensor, flame detector, oxygen sensor.

The utility model adopts the inner-outer sleeve fit structure, simultaneously at outer wall of inside race device helical blade, inner sleeve inner wall device hot baffle, increase greatly heating surface area, improve rate of heat exchange, adopt thermoswitch, photoelectric sensor, flame detector, oxygen sensor, the automatic control system that particularly adds oxygen sensor to form, the whole automatization level that improves, adopt simultaneously fume purifier, clean burning is eliminated flue dust, characteristics with high-efficiency environment friendly, particularly suitable agricultural greenhouse support plant, the industrial production such as villa and local-style dwelling houses life use heat energy.
