Description

Heat transfer oil heater

Technical field

The utility model relates to a kind of heater, especially a kind of employing heating heat-conducting oil stove.

Background technology

At present, in industry, bathing industry and central heating, generally adopt water,,, must therefore need to consume a large amount of fuel constantly to the water heating in order to reach higher temperature because the boiling point of water is lower as heat medium.Especially to winter, the resident in the north adopts central heating usually in order to keep out the cold, and promptly at every family caliduct and radiator is installed, by the heat supply of collective of heat supply company.According to long operating position, collective's heating exposes the defective of himself gradually: at first, the traditional coal of thermal source employing in the heat supply company acts as a fuel water is heated, simultaneously suitable pressurization, to improve the boiling point of water, but the boiling temperature of the water that improves by pressurizeing is limited, and along with the rise of coal price in recent years, the cost of central heating is also more and more higher; In addition, the employing central heating must be at the underground large diameter pipeline of burying underground, so that with delivery to resident family, when the distance between heat supply company and the residential building is far away, not only need a large amount of conveyance conduits, but also must destroy the road surface, increased the investment that the road surface is built on the one hand, improved the cost of investment of central heating greatly, also brought inconvenience on the other hand for people's trip.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned defective that exists in the existing central heating, a kind of heat transfer oil heater has been proposed, this heating furnace has changed traditional heat medium, can improve heating-up temperature, increase heating surface area, save the use amount of fuel, reduced the cost of burying underground of the use amount of heat supply pipeline and pipeline, reduced heat cost.

The utility model is to adopt following technical scheme to realize: a kind of heat transfer oil heater, comprise Heat Room, flue and oil guide pipe, the inner chamber of Heat Room is provided with oil guide pipe, the bottom of Heat Room is provided with the combustion chamber, wherein, described oil guide pipe forms from top to down or from going up to coil continuously down along the circumferential side wall of Heat Room, and by the Heat Room sidewall to its inner chamber layering around, closely arrange between the levels oil guide pipe, the gap promptly is not set, be provided with certain distance between the ectonexine oil guide pipe, this is apart from forming the annular heat flue, and this annular heat flue is connected with the flue at Heat Room top.Discharge heating furnace along the annular heat flue under the effect of the hot cigarette air blast in the combustion chamber that produces after the fuel combustion, in the annular heat flue in the process of flowing, with the deep fat that adds in the heat transferred oil guide pipe, simultaneously can make the part flue dust that produces behind the coal burning stop dropping on the oil guide pipe, reduce pollution air.

In the utility model, in order to improve the heating surface area of oil guide pipe, described oil guide pipe is surrounded with two-layer at least to its inner chamber by the heating furnace sidewall, and its concrete number of plies can be determined according to the volume of heating furnace and concrete heating needs.The top of described Heat Room inner chamber is provided with a back taper accumulator, it is located at the below of Heat Room top flue, the oil-in of this accumulator is the oil-out of oil guide pipe, the oil-out of accumulator is arranged on the top of Heat Room, the oil-in that is oil guide pipe is located on the Heat Room sidewall, and oil-out is connected with accumulator.Be provided with oil pump between the oil-in of oil guide pipe and the oil-out of accumulator.Realized flowing of conduction oil in oil guide pipe and the accumulator by oil pump, so that conduction oil is heated evenly.The hot cigarette that produces in the combustion chamber can at first heat the conduction oil in the accumulator before discharging along the annular heat flue, makes full use of the heat that fuel combustion produces.

The shoulder of Heat Room is provided with storage tank, and the hot cigarette that fuel combustion produces is during to heat-conducting oil heating, and the sidewall of Heat Room will certainly heat up, and utilizes this temperature that the water in the storage tank is heated, and makes full use of heat.

Corresponding oil guide pipe below is provided with annular ash accumulating chamber along the heating furnace circumferential side wall, and the bottom of ash accumulating chamber is connected with ash releasing tube.The flue dust that drops on the flue dust of oil guide pipe and fall into ash accumulating chamber in cyclic process can be discharged from heating furnace by ash releasing tube.Ash releasing tube can be provided with continuously along the circumferential bottom of ash accumulating chamber, also can be provided with at interval.

In order suitably to reduce the pollution of sulphur contained in the flue dust of fuel combustion generation to environment, can be provided with the washing type deduster at the top of Heat Room, this deduster comprises container that fills limewash and the sprayer unit that has shower nozzle, the container that fills limewash is provided with air inlet and gas outlet, air inlet communicates with the flue at Heat Room top, constantly limewash is evacuated in the sprayer unit by suction pump, the limewash that shower nozzle forms is sprayed onto in the limewash container.

This heat transfer oil heater can use coal, coal gas or natural gas to act as a fuel, and conduction oil is generally high-temperature silicon oil.During the utility model work, make the fuel combustion in the combustion chamber, the hot cigarette that burning is produced by air blast dashes to Heat Room, what at first contact with hot cigarette is the accumulator that is back taper, oil in the accumulator is heated, along the heat-conducting oil heating of annular heat flue to circulating in the oil guide pipe, at last the flue along the Heat Room top flows out with the after heat cigarette, and the washing type deduster by the Heat Room top removes dust and the part sulphur in the cigarette that reduces phlegm and internal heat.After the conduction oil of mobile heating flows out from heating furnace in oil guide pipe, can exchange hot water by heat exchanger, heated hot water can be used for bathing industry or central heating etc., and the conduction oil of outflow enters next circulation heating process from the oil guide pipe oil-in once more by oil pump.

The beneficial effects of the utility model are: replace traditional water as heat medium by conduction oil, improved the boiling point of heat medium, improved heating-up temperature, reduced the use amount of fuel; In addition, oil guide pipe from top to bottom, being coiled to form from outside to inside around the mode layering, hot cigarette is flowed along the circular passage, increased the heating surface area of conduction oil, simultaneously owing to prolonged hot cigarette channel, make that most flue dust is attached to the oil guide pipe surface in the hot cigarette, ash accumulating chamber and ash releasing tube by the oil guide pipe below are concentrated discharge from heating furnace, simultaneously the washing type deduster is set in the exit of Heat Room top flue, this deduster plays the effect of desulfurization, reduced the pollution of flue dust, reached the purpose of energy-saving and emission-reduction air; This equipment can be used for the central heating of residential quarter in addition, and the investment that required a large amount of heat supply pipelines and road surface are built when having reduced remote carry greatly reduces the cost of investment of central heating.
