Description

Aqueous hydrocarbon infrared energy-conserving cooking stove

The utility model belongs to the Civil energy-saving cooking stove technical field, is the energy-saving cooking that a kind of Jiang Shui and oil or water and combustion gas mixing vaporization after-combustion produces infrared waves.

It is reported, big (the per hour oil consumption that has reaches 6.5 kilograms), the thermal efficiency low (being about 51%) of the Oil-burning range ubiquity fuel consumption of Xiao Shouing, noise height (60～80 decibels), burning are insufficient in the market, the flue dust and the carbon monoxide of discharging are many, shortcomings such as serious environment pollution, and price is up to 8000～9000 yuan.For energy savings, improve the thermal efficiency, reduce environmental pollution, each discloses " a kind of oil-water mixed combustion stove " and " the civilian evaporation furnace of a kind of fuel oil water " Chinese patent CN2218887Y and CN2224352Y.The technical characterstic of these two kinds of cooking stoves all is the mist of gained after fuel oil and the water vapor to be acted as a fuel burn, though they have all overcome the shortcoming of existing Oil-burning range to a certain extent, but its structure is all comparatively complicated, and it is energy-conservation and the thermal efficiency is all not ideal enough.

Task of the present utility model is to overcome the defective that prior art exists, plan provides a kind of simple in structure for civilian cooker field, energy-saving effect is remarkable, flame temperature height, vaporize, sufficient combustion, thermal efficiency height, noise reduction, smoke medicining dust-removing effect are good, the cooking stove that can produce infrared waves.

Task of the present utility model is finished by a kind of like this technical scheme: promptly mainly comprising on the prior art basis of stove body, burner, generating tube, oil storage tank, water tank, carrier pipe, by-pass valve control, its burner design is the tubaeform container of a upper end open, this container is positioned in the stove body, have the aperture on the wall, upper inside wall has a ring-shaped step, place infrared sieve shape web plate on it, bottom straight up the circular cylinder that is connected, have the aperture on the barrel, this aperture is one of them aperture correspondence of being opened on the burner wall.This is to the horizontal respectively infundibulate air inlet pipe that is equipped with in another aperture of opening on aperture and the burner wall, and the air inlet pipe end lays respectively in the cylindrical shell and outside the cylindrical shell.Generating tube is a straight tube, and across being fixed on the burner, the port of export is connected with nozzle, and nozzle is fixed in the infundibulate air inlet pipe horn mouth.Carrier pipe between oil storage tank, water tank and the generating tube is one, communicates with it by communicating pipe respectively.

During use, open the by-pass valve control of oil storage tank earlier, make fuel oil along communicating pipe, carrier pipe, generating tube, burn in the combustion chamber that enters burner through nozzle, open the by-pass valve control of water tank subsequently again, water and oil are mixed through entering carrier pipe communicating pipe, and the generating tube vaporization of burner top that continues to flow through of mixed liquid sprays from nozzle then.Because the speed of ejection is exceedingly fast, and forms negative pressure in the horn mouth of infundibulate air inlet pipe, thereby can carries air rapidly and enter burner from the air door of fixed nozzle.When by extending into after mixed airflow in the infundibulate air inlet pipe of burner tube inside and outside is flushed to the cylindrical shell inside and outside wall, promptly be engraved in the inside and outside whirlwind eddy current that forms of cylindrical shell, make its further mixing, rising to the combustion chamber then fully burns, and by the flame temperature of infrared sieve shape web plate generation temperature up to 1000～1300 ℃, can vaporize to the water, the oil that enter in the generating tube better on the one hand, can under equal conditions satisfy more people's the demand of having a dinner on the other hand.

Accompanying drawing is a structural representation of the present utility model.

Also the utility model is described in further detail to provide embodiment below in conjunction with accompanying drawing.

Embodiment:

As shown in the figure, the aqueous hydrocarbon infrared energy-conserving cooking stove showed of present embodiment mainly comprises stove body 1, burner 2, generating tube 9, oil storage tank 15, water tank 16, carrier pipe 13, by-pass valve control 17.

Wherein stove body 1 is an open-ended cavity, and inwall is built the refractory brick (not shown), and with fire-proof and thermal-insulation, wall one side in chamber has air inlet, and opposite side has the conveying pore, and burner 2 is arranged in stove body 1.

Burner 2 is the tubaeform container of a upper end open, and upper inside wall has a ring-shaped step 3, and this ring-shaped step 3 of present embodiment is to be changed by the wall thickness to form, and places infrared sieve shape web plate 8 on it, makes it both to produce energy-conserving action, reaches noise reduction noise control purpose again.Bottom straight up the circular cylinder 4 that has been connected, the burner 2 wall evaginations of cylindrical shell top increase the combustion chamber diameter that is positioned at infrared sieve shape web plate 8 belows, with infrared sieve shape web plate 8 size couplings.Circular cylinder 4 barrels one side has the aperture, and one of them aperture of being opened on this aperture and burner 2 walls is corresponding.This is to the horizontal respectively infundibulate air inlet pipe 5 that is equipped with in another aperture of opening on aperture and burner 2 walls, the horn mouth of air inlet pipe 5 small one and large one, be positioned at burner 2 same outer hand hay cutters, it is inside and outside that the port of export lays respectively at circular cylinder 4.For combustion-supporting, make institute advance the air abundance, on burner 2 walls of two air inlet pipe 5 peripheries, be fixed with the trumpet-shaped wind-collecting cover 6 that is rectangle, this wind-collecting cover 6 is positioned at stove body 1 air inlet place.

Generating tube 9 is a straight tube, and is totally two, parallel across being fixed on the burner 2.Exchange for conveniently in order to process to install, the generating tube 9 of present embodiment is cast directly on the annular slab 10, and is connected by the lug screw 7 usefulness connectors and the burner 2 of annular slab 10.Generating tube 9 one ends respectively connect a nozzle 11 by two tube connectors 12, and nozzle 11 is fixing wherein by the air door in infundibulate air inlet pipe 5 horn mouths, and the other end of generating tube 9 linked to each other with the carrier pipe 13 that passes stove body 1 by communicating pipe 14 (being three-way pipe).

Carrier pipe 13 is one, and its other end links to each other with by-pass valve control 17 under the water tank 16 by communicating pipe 14 (also being three-way pipe) and oil storage tank 15.During use, the bottom of oil storage tank 15 and water tank 16 should be higher than cooking stove.If without fuel oil, also can change oil storage tank 15 into air accumulator, with liquefied gas or directly replace fuel oil with natural gas.

Compared with the prior art the utility model has the following advantages:

1. simple in structure, easy to install;

2. energy-saving effect is remarkable, per hour oil consumption 2～3kg;

3. the flame temperature is high, can reach 1000～1300 ℃, thereby make the water of the generating tube of flowing through, and oil is vaporized sufficient combustion, thermal efficiency height.

Because vaporize, sufficient combustion, used infrared sieve shape web plate again, thereby noise reduction, smoke medicining dust-removing effect are good.
