Description
Technical field
The present invention relates to a kind of improved pure smokeless, coal saving type heat transfer oil stove with external combustion and inner rotational flow, belong to Thermal Equipment.
Background technology
Heat-conducting oil furnace belongs to boiler of organic heat carrier, is a kind of novel industrial boiler that just develops rise recent years, because volume is little, installs and flexible arrangement, and operating cost is low, receives praises from customers, and market prospects are wide.
Boiler of organic heat carrier is fuel with the fire coal, with the conduction oil is medium, utilizes oil circulating pump to force conduction oil to carry out the liquid phase circulation, and heat energy is flowed to the hot equipment of using by pipeline, conduction oil after overheated transmission cooling is got back to heating furnace by Returning pipe again and is reheated, and forms closed cycle.
Owing to use oil as heat transfer medium, can under lower pressure, obtain higher operating temperature (about 300 ℃), can control temperature accurately, need not water resource and water treatment facilities, service condition there is not harsh demand, can accurately control temperature, and simple structure, the maintenance and move very convenient, be a kind of safety coefficient than higher heating equipment, be widely used in industries such as weaving, printing and dyeing, food processing, paint coating, chemical industry equipment, materials for construction, artificial leather, wood-based plate, papermaking, timber production.
Boiler of organic heat carrier is the same with common coal combustion equipment, the flammable effective ingredient in the bituminous coal---fugitive constituent (accounting for 30%-35%), almost to arrange to atmosphere with the form of black smoke all, and environmental pollution and energy waste are very serious.Burn boiler of organic heat carrier for vertical hand, it all is the less product of power ratio, but market capacity is but very big, the kind model is also a lot, between the equipment contrast that each enterprise produces some difference are arranged all, combustion power generally (also claims 0.125-2.8MW) between 125KW-2800KW, the former coal consumption is 1,5 ton/24 hours, and the latter's coal consumption is 13-15 ton/24 hour (calculating by workman's three or eight systems of going to work).Coal-fired over-emitting black exhaust problem is quite serious, and the coal resource waste also is quite surprising.
Summary of the invention
The object of the present invention is to provide a kind of improved pure smokeless, coal saving type heat transfer oil stove with external combustion and inner rotational flow, can solve coal-fired over-emitting black exhaust problem, save coal resource, improve the thermal efficiency, the protection environment.
Pure smokeless, coal saving type heat transfer oil stove with external combustion and inner rotational flow of the present invention, the top of body of heater is the thermal treatment zone, be fitted with heat-conducting oil pipes in the body of heater of the thermal treatment zone, the top of the thermal treatment zone is provided with air-introduced machine, the bottom of body of heater is the fire coal district, and coal-fired district is fitted with coal-burning installation, and its coal-burning installation comprises coal fired combustion and the interior cyclone burner of body of heater that body of heater is outer, coal fired combustion has coal-fired furnace cavity, fire grate and coal filling hole, and there is exhanst gas outlet at the rear portion of coal-fired furnace cavity; Cyclone burner has the rounded vortex furnace of cross section, the high-temperature gas outlet is arranged above the vortex furnace, air inlet is arranged below, there is gas approach the side, the eddy flow direction of the gas approach of vortex furnace and vortex furnace is tangent, adapt with gas approach, be provided with the combustion-supporting air port of eddy flow, the exhanst gas outlet of coal-fired furnace cavity and the butt joint of the gas approach of vortex furnace in other cooperation of the side of gas approach.
Air-introduced machine makes and forms negative pressure in the body of heater, in coal fired combustion, the combustion air that enters from fire grate promotes burning coal-fired on the fire grate, a large amount of tar steam, carbon monoxide, black smoke and other hydrocarbon gas formed by small carbon granules, form unburnt product, pour in vortex furnace from exhanst gas outlet together, under the boosting of combustion air, the result of eddy flow mixes flue gas and combustion air (oxygen), cause fierce burning, form high temperature, burn-off rate reaches 100%.Through the clean high-temperature gas that obtains behind the thorough combustion oxidation, rise operation on while rotate, drawn by air-introduced machine through outlet, when flowing through the body of heater thermal treatment zone, heat-conducting oil pipes is heated, this thermal current that has been reinforced has strengthened heat-transfer effect, has improved the thermal efficiency.As required, combustion-supporting air port also can distribute be provided with several.
The present invention makes the whole oxidations of the fugitive constituent of shared composition 30%-35% in the bituminous coal (forming product is the dry saturated steam of carbon dioxide and water) become heat energy, realizes 100% coal-fired burning, and economizing on coal reaches 30%-35%.Vortex furnace resembles cyclone dust collectors, the swirl flow combustion that black smoke is burned, and the incombustibility dust of wherein carrying secretly falls because of the gravity effect, falls through air inlet,, is conveniently focused in the ashpit of bottom by centralized collection.
In this burning system, discharge without any flue gas, the waste gas of discharging is colourless, tasteless, transparent, with the naked eye can't see, lingemann blackness has not existed at all, and coal fired combustion is positioned at outside the body of heater again, finish the solid burning of coal at this, vortex furnace is positioned at body of heater, finishes the thorough burning of flue gas at this, so be called pure smokeless, coal saving type heat transfer oil stove with external combustion and inner rotational flow.
Clean clean red-hot air-flow and in the thermal treatment zone of body of heater, carry out heat exchange with heat-conducting oil pipes, the conduction oil of heat-conducting oil pipes is heated, provide power that heat energy is sent in streams to a place with on the hot equipment by the work oil pump, conduction oil after the release heat returns boiler of organic heat carrier by oil returning tube, reheated, formed closed cycle.
Among the present invention:
The combustion-supporting air port of eddy flow places the inboard of gas approach, and the formation of the eddy flow of being convenient to burn promotes fully burning.
For some large-scale heat-conducting oil furnaces, can consider to increase a coal fired combustion, make two coal fired combustions be distributed in the periphery of vortex furnace, preferably be symmetrically distributed easy smooth combustion operating mode, operation also easy to install and use.
Coal fired combustion can be coal-fired right the device that is fit to arbitrarily, as long as the solid fire coal can be fired into flue gas, gets final product for vortex furnace provides the flue gas of further burning.Divide from fire grate, common having is fixed, movable, movable in the middle of, have again oscillatory type with rock type, or the like; Divide from body, microscler again, square and circle, or the like.
Pure smokeless, coal saving type heat transfer oil stove with external combustion and inner rotational flow of the present invention, simple in structure, cheap; implement easily; can directly on existing boiler of organic heat carrier, improve, thoroughly solve coal-fired over-emitting black exhaust problem, the waste gas water white transparency of discharge, clean, pollution-free; reached pure smokeless effect; lingemann blackness is 0, has both saved coal resource, has improved the thermal efficiency; protected environment again, economic benefit and obvious social benefit.
