Description

A Shuttle Furnace Combustion Radiator Using Liquid Fuel in a Matching Density Barn

technical field

The utility model relates to a shuttle-shaped hearth combustion radiator which uses liquid fuel in a matching dense barn.

Background technique

Tobacco leaf curing is a process that consumes a lot of energy. In China, the process generally generates heat by burning coal fuel in the stove, and then heats the air in the curing room through heat dissipation equipment, so that the tobacco leaves turn yellow, dehydrate and vaporize into the air, forming damp heat. The air is exhausted outside the barn, and coal burning and roasting tobacco leaves will not only produce NOx, SO2 and CO and other gases that pollute the environment, but also require continuous labor operations such as adding coal, stirring the fire, and removing slag during roasting, and it is difficult to bake. Precise temperature control, part of the coal slag will fall with the slag, resulting in waste of fuel; in order to change the energy supply method of burning coal for baking, many producers have carried out the application test of "non-coal" fuel in tobacco leaf baking, For example, various heating methods such as electricity, straw and firewood, boilers and other heating methods have been tried for baking, but due to the limitations of equipment prices, combustion costs and inconvenient use, it has not been widely used in tobacco leaf production areas. ; The use of liquid fuel for tobacco leaf baking is a good fuel to replace coal. At present, there are few researches in China. Liquid fuels such as gasoline, diesel and alcohol-based fuels, especially alcohol-based fuels, are very Clean fuel, the calorific value is generally between 20100~26000 kJ/kg, because the fuel itself contains oxygen, less oxygen is needed during combustion, the fuel burns fully, showing a blue flame, and the flue gas does not contain carbon particles, mainly carbon dioxide And water, there is no gas polluting the air, and there will be no sulfide production that corrodes the metal radiator. Therefore, it is necessary to design a flue-cured tobacco heating equipment dedicated to liquid fuel to replace coal. Baking heat is not only safe and environmentally friendly, energy-saving and hygienic, but also can reduce the labor intensity of tobacco farmers. It is an effective way to improve the production environment of tobacco farmers and increase economic benefits.

Contents of the invention

The purpose of the utility model is to provide a shuttle-shaped furnace combustion radiator that can replace coal to provide baking heat and is used for supporting dense barns to use liquid fuel.

The utility model adopts the following technical scheme: a shuttle-shaped furnace combustion radiator using liquid fuel in a dense barn, which consists of a shuttle-shaped furnace shell, a secondary combustion channel, a heat collection and diversion cabinet body, and a heat collection and distribution cabinet body two. It is composed of a flue gas box. One end of the shuttle-shaped furnace shell is provided with a liquid burner interface, and the other end is connected to a secondary combustion channel. The other end of the secondary combustion channel is connected to the heat collecting and diverting cabinet. The upper part of the heat diversion cabinet body is connected side by side with a group of heat dissipation finned tubes. The heat dissipation finned tubes are folded into multiple U-shaped bends to increase the heat dissipation area. Unicom, the upper part of the heat collecting and diverting cabinet body two is connected with the flue gas box, and the upper side of the flue gas box is provided with a smoke exhaust port.

The beneficial effects of the utility model are: reasonable design, high calorific value, fast temperature rise, balanced heat dissipation, reduced flue-cured tobacco furnace volume and radiator area, and because liquid fuels are burned, especially alcohol fuels, CO2 and water are excluded Compared with coal-fired and biomass radiators, it does not produce tar or corrosive gas to corrode or block the furnace. It is energy-saving, environmentally friendly, safe and hygienic. It can provide sufficient heat to meet the needs of baking in the key link of flue-cured tobacco dehumidification. The curing quality of the tobacco leaves can be obviously improved, the labor intensity of the tobacco farmers is reduced, and the economic benefits are improved.

Detailed ways:

As shown in the figure, a shuttle-shaped furnace combustion radiator using liquid fuel in a dense barn is composed of a shuttle-shaped furnace shell 2, a secondary combustion channel 3, a heat collection and distribution cabinet 4, and a heat collection and distribution cabinet 2 6 and a flue gas box 7, one end of the shuttle-shaped furnace shell 2 is provided with a liquid burner interface 1, and the other end is connected to a secondary combustion channel 3, and the other end of the secondary combustion channel 3 is connected to the heat collecting and diverting cabinet One 4 Unicom, the upper part of the heat collecting and diverting cabinet 4 is connected side by side with a group of heat dissipation finned tubes 5, and 5 of the heat dissipation finned tubes are folded into a plurality of U-shaped bends to increase the heat dissipation area, and the heat dissipation finned tubes The other end of 5 is in communication with the heat collecting and diverting cabinet body 2 6, and the above said heat collecting and diverting cabinet body 2 6 is in communication with the smoke box 7, and the smoke exhaust port 8 is arranged on the smoke box 7.

When using this embodiment, connect the liquid burner interface 1 of the device to the liquid burner, turn on the baking automatic controller, the liquid burner is under the control of the automatic controller, the liquid burner sprays and evaporates the liquid fuel, and burns The inside of the burner is ignited and burned by electrons. The linear flame enters the shuttle-shaped furnace shell 2 through the liquid burner interface 1 to heat the shell of the shuttle-shaped furnace. The shuttle-shaped furnace enters the secondary combustion channel 3, and the mixed hot air contains oxygen and atomized unburned atomized liquid fuel. After the secondary combustion releases heat under high temperature conditions, the hot air enters the heat collecting and diverting cabinet 1 4 After the initial concentration, the negative pressure begins to flow to the heat dissipation finned tube 5, and the hot gas flowing into the heat collection and distribution cabinet 2 6 through the heat dissipation fin tube 5 is mixed for the second time, and flows through the heat collection and distribution cabinet 2 6 shell to The heat is dissipated in the barn, and then gathered to the flue gas box 7 for three times mixing to dissipate heat in the barn, and finally discharged through the smoke exhaust port 8. When the roasting is completed, the liquid burner stops burning under the control of the automatic controller.
