Abstract
The invention discloses a drum type hot-blast stove which is characterized in that heat exchange tubes of heat exchangers of the stove are of a structure that drums are circumferentially and uniformly distributed, the drums rotate and roll at low speed when in use, the heat exchange tubes are uniformly heated, dust does not accumulate on the surfaces, flue gas channels are smooth, the drum type hot-blast stove cannot be burned out due to too high temperature and cannot be eroded due to too low temperature, and biofuel such as coal, waste crops and the like can be used as energy sources. Air ducts and flues are of reverse flow structures, i.e. cold air flows from a low-temperature area to a high-temperature area, so that heat which is released by fuel burning is effectively switched; left and right bellows can be freely removed, so as to facilitate the maintenance of the heat exchangers in the stove; second high-temperature air supply is adopted in a hearth, so as to guarantee sufficient burning of the fuel; the drum type hot-blast stove is mainly used for drying or heating products, heating for enterprise units and heating for production and cultivation and has the using effects of energy conservation, high efficiency and durability.
Description
Technical field
The heat-exchange tube of heat exchanger of the present invention adopts cylindrical barrel to be uniformly distributed structure, during use, low speed rotation is rolled, each heat-exchange tube is heated evenly, surface is dust stratification not, and exhaust gases passes is unimpeded, and Yin Wendu is too high and burn out, also Yin Wendu is too low and corrode, be the hot-blast stove of the bio-fuels such as a kind of available fire coal, waste agronomic crop as the energy, be mainly used to dry, heating, heating, have more energy-conservation, more efficiently, more durable result of use.
Technical background
The dryer of current use or hot-wind heating equipment are generally electrical heating and bio-fuel burns two kinds, large with electrically heated electricity consumption of equipment, use cost is expensive, and not easily designing high-power equipment: hot-blast stove effect of existing bio-fuel is low, energy consumption is large, equipment is heavy, due to Physical design factors, heat exchanger or furnace wall easily burn out or corrode, and maintenance difficult, service life is short, and its fume emission does not meet environmental protection standard.
Large-scale production cultivation must possess greenhouse experiment in the winter time, and because not having reasonable heating equipment, most enterprise all faces winter heating difficulty.
Face warming problem away from the industrial and mining enterprises of central heating or general medium-sized and small enterprises, or cost is high, or effect is low, and pollution problem can not get solving, and has a strong impact on the development of these medium-sized and small enterprises, particularly underdeveloped border district always.
Product needs the enterprise of the oven dry of large area, high efficiency or drying because plant capacity is large, power consumption large, also faces the predicament of production cost costliness.
Summary of the invention
The heat exchange device layout of original stationary distribution becomes cylindrical barrel to be uniformly distributed the heat exchanger of structure by the present invention, rolled by its low speed and rotate, there is not fouling phenomenon in its any heat exchange part, flue portion can guarantee that flue gas is unblocked all the time, each heat-exchange tube is heated evenly, farthest can absorb the heat energy that fuel combustion discharges, thus reach ceiling capacity conversion effect.
The present invention adopts air channel and flue reverse flow, and namely cold air flows to high-temperature region from low-temperature space, more effectively switches the heat energy that fuel combustion discharges.
The present invention is designed to detachable apparatus, is conducive to the periodic maintenance maintenance of equipment, guarantees the stability of equipment thermal power.
The present invention adopts secondary hot-air Thorough combustion principle, contribute to fuel combustion more fully, more complete, guarantee that fuel availability reaches optimum efficiency, flue gas hazard substance control reaches optimum state.
The present invention adopts the heat exchange principle of rotary rolling because be heated evenly, heat exchanger can not Yin Wendu too high and burn out, also can not Yin Wendu too low and corrode, guarantee its service life.
The present invention is at the grey cloth bag of body of heater floss hole design gear, and the dust produced after effectively stopping abundant fuel combustion and particle, reach exhaust emissions requirement.
The present invention adopts the heat exchange principle of rotary rolling, under the prerequisite not affecting hot exchange power, and can the volume and weight of effective reduction equipment.
The present invention is mainly applicable to the oven dry of large-scale product, dry or heating, has efficient, clean, low cost feature.
Winter heating problem, particularly rural area that the present invention can solve large-scale farming production have a large amount of waste agronomic crop to can be used as the renewable sources of energy of the present invention, and both environmental protection, can reduce costs again, and the ashes of generation can be used as organic fertilizer, are used for applying fertilizer or transferring the possession of.

Detailed description of the invention
The bio-fuels such as right coal, waste agronomic crop are shoveled the fire grate 1 of burner hearth 2 from fire door 3, open small blower, air at room temperature is allowed to enter from secondary air inlet pipe 26, high-temperature hot air in burner hearth hot bellows 21 is blown in burner hearth 2 by the hot air duct 4 around multiple distribution burner hearth 2, allows full combustion of fuel.
Open gearbox motor power, allow transmission sprocket 19 by gearbox chain 20 and double chain wheel 23, drive high-temperature heat exchanger 6 rotary rolling, double chain wheel 23 is by driving chain 24 and sprocket wheel 25 simultaneously, synchronous drive low temperature heat exchanger 7 rotary rolling, angular speed controls at about 6 revs/min.
Open large air blast, clean cold air is allowed to enter from cold wind inlet tube 18, successively by packaged air conditioner 17, low temperature heat exchanger 7, air channel commuting case 22, high-temperature heat exchanger 6, hot bellows 16 and hot-blast outlet pipe 12, discharge temperature required clean hot-air, be used for drying or heating.
The high-temperature flue gas that fuel produces after Thorough combustion in burner hearth 2, after high-temperature heat exchanger 6, furnace wall 5 and low temperature heat exchanger 7, directly become the low-temperature flue gas of about 100 DEG C, enter ash box 10, low-temperature flue gas is diffused into the grey cloth bag 9 of gear by gas baffle 8 and filters, finally discharge from exhaust pass 11, reach environment protection emission requirement.Require that cigarette ash and ashes do periodic cleaning.
Import and export end breather line 28 and the body of heater furnace wall 5 of low temperature heat exchanger 7 and high-temperature heat exchanger 6 all have graphite grazing pad 13 to make encapsulation process, guarantee that flue gas does not enter air duct.
