Description

Energy-saving oil-combustion hot-air furnace
Technical field
The present invention relates to prepare the heat power supply device of hot-air, be specifically related to a kind of warm air oil furnace, it is widely used in the baking-curing of coating process, the drying of tobacco, the drying and moulding of timber, the shaping and drying of textile printing and dyeing full line industry etc. and needs hot-air heated technology occasion.
Background technology
Industrial, many technology occasions that need the hot air oven dry are arranged: as the baking-curing of coating process, the drying of tobacco, the drying and moulding of timber etc., the hot-blast stove that these occasions are used is divided into warm air oil furnace, fuel gas hot-blast stove etc. by the difference of heating energy source.
Fuel gas hot-blast stove is gases such as natural gas, liquefied gas because of burning, it is less to produce flue gas in the burning, therefore can adopt direct-fired structure on the structure, direct-fired structure is exactly directly to spray the sunken burning of fire in combustion chamber (or claiming combustion barrel) with burner to produce hot-air, the uncovered direct discharge of these hot-airs on combustion chamber (or claiming combustion barrel) plays baking or desiccation, and the thermal efficiency is higher.And warm air oil furnace is a burning diesel oil because of it, and general burning is all insufficient, can produce a large amount of flue gases in the burning, and as if adopting direct-fired structure, a large amount of flue gases are discharged with hot-air, can directly influence normally carrying out of step baking drying process down.Therefore, at present people think that mostly warm air oil furnace can't be designed to direct-fired structure, and what generally adopt is the heat exchange type structure.The heat exchange type structure is located at combustion chamber (or claiming combustion barrel) in the heat exchanging chamber exactly, the combustion chamber passes on the outlet flue (chimney) of heat exchanging chamber through long smoke pipe in heat exchanging chamber, in combustion chamber (or claiming combustion barrel), spray fire with burner and fall into burning, high-temperature flue gas in the combustion chamber is discharged by outlet flue through smoke pipe, the gas of high-temperature flue gas in chamber wall and long smoke pipe wall and Heat Room carries out heat exchange in discharge process, will discharge baking or desiccation after the air heat in the Heat Room again.The structure of typical case's representative of the warm air oil furnace of existing heat exchange type, visible Chinese patent communique was announced on May 15th, 2002, and the patent No. is 01246080.X, and name is called the utility model patent of " warm air oil furnace ".The warm air oil furnace of above-mentioned existing heat exchange type structure is because of process gas-gas heat transfer process, the flue-gas temperature that outlet flue (chimney) is discharged still up to 350 ℃ about, not energy-conservation, the thermal efficiency lower (reaching 60~70% at most), and fin such as adjunction fin are also wanted in the long coiling of smoke pipe on the smoke pipe, complex structure, manufacture difficulty strengthens.
Summary of the invention
The present invention is insufficient for solving the oil inflame that exists in the prior art, the generation flue gas is many, cause adopting only the heat exchange type structure, the thermal efficiency is low, not energy-conservation, and structure is complicated, the technical problem that manufacture difficulty strengthens is studied from the angle that improves sufficient combustion and minimizing flue gas, and a kind of novel energy-saving oil-combustion hot-air furnace is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of energy-saving oil-combustion hot-air furnace, mainly constitute by combustion barrel, heating clamber and blower fan, heating clamber is a gas heat tunnel, this passage is provided with air inlet and air outlet, blower fan is positioned on the circulation path of heating clamber, forces air-flow to flow to the air outlet direction from air inlet; Combustion barrel is located in the heating clamber, leaves the circulation of air space between periphery that combustion barrel directly makes progress and chamber walls; Combustion barrel is a cannular combustion chamber, the one end is a firing tip, connect for joining oil burner outward, other end sealing is as the anti-end that burns of retaining fire, the barrel of firing tip circumferentially evenly offers one group of louvre, the anti-barrel that burns end of retaining fire circumferentially evenly offers one group of bloop, and the aperture of described louvre is greater than the aperture of bloop.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described " combustion barrel is a cannular combustion chamber; the one end is a firing tip; connect for joining oil burner outward, and other end sealing is as the anti-end that burns of retaining fire " is meant: an end of combustion barrel is named as firing tip, should link to each other with outer accessory oil burner (or claiming Oil-combustion combusting machine), the other end of combustion barrel is then with sealed port of butt end, as the anti-end that burns of retaining fire, this end face promptly has been the retaining fire action, and fire is fallen into because of the reverse second-time burning of stopping of this end face.
2, in the such scheme, described combustion barrel lateral arrangement is in an end of heating clamber, and the other end of heating clamber is provided with described blower fan, and this blower fan is an axial flow blower, respective shaft flow fan side is established described air outlet on the heating clamber, and the louvre side of corresponding combustion barrel is established described air inlet.
3, in the such scheme, described bloop is difficult for out greatlyyer, general aperture≤8mm.
4, in the such scheme, described combustion barrel is cylindrical, the fire of combustion barrel size and oil burner ejection falls into size and matches, long 20cm~the 28cm of length (best 25cm) that the fire that the length of combustion barrel sprays than oil burner falls into, and about the big 15~20cm of diameter that the fire that the diameter of combustion barrel sprays than oil burner falls into.When burner during greater than 300,000 kilocalories, also need suitably to strengthen the size of combustion barrel, help abundant second-time burning like this and reduce the generation of nitrogen oxide.
5, in the such scheme, the anti-sealing inner face that burns end of the retaining of described combustion barrel fire is provided with the fiery conical surface of retaining.
6, in the such scheme, described louvre group can divide for three to the four barrel weeks of enclosing the firing tip that is evenly arranged in combustion barrel made progress.
7, in the such scheme, described bloop group also can divide for three to the four barrel weeks of enclosing the retaining fire end that is evenly arranged in combustion barrel made progress.
Because the technique scheme utilization, the present invention compared with prior art has following advantage and effect:
The present invention is owing to adopt the combustion barrel of end sealing, the barrel week of the firing tip of this combustion barrel upwards is provided with louvre, fire falls into and sprays in the combustion barrel through this firing tip during work, fire falls into after the retaining fire of its sealing instead burns stopping of end, flue gas and fire fall into reverse second-time burning, make oil inflame ground more abundant, discharge a small amount of flue gas and high heat through louvre more at last, these high heat are directly discharged as baking usefulness by blower fan, and are more energy-conservation, the thermal efficiency is high (thermal efficiency can reach about 95%).In above-mentioned second-time burning process, the effect of bloop is: 1, prevent detonation, make burning more abundant; 2, receive the outer little air of combustion barrel by bloop, auxiliary second-time burning makes burning more abundant.And this hot-blast stove just is made of combustion barrel, heating clamber and blower fan, also has advantage simple in structure, easy to make.
