Abstract
The invention provides an oven with a tar recovery device. The oven can improve the utilization rate of fuels and reduce the pollution to the atmosphere. The oven comprises an oven body; the inner chamber of the oven body is provided with a grate; the oven also comprises a fuel funnel; a spiral conveying pipe is arranged between the fuel funnel and the grate; a ventilation pipe which is communicated with a fan is arranged under the grate which is arranged in the oven body; a venturi pipe is arranged in the ventilation pipe; a flue gas return pipe is arranged between the spiral conveying pipe and the throat portion of the venturi pipe.
Description
Technical field
The present invention relates to agricultural machinery, being specifically related to a kind of is the supporting heating plant of crops drying equipment.
Background technology
In the crops large-scale production operations such as tobacco leaf, medicinal material, fruit, after bright leaf (fresh fruit) results, need to be dried operation, its thermal source is generally used baking oven, and fuel is used coal cinder, and the baking oven sidewall arranges fuel funnel, in stove, continues to add coal cinder.Find to leak the coal bunker place yellowish cigarette of sometimes emerging in dry run, the mixture that is steam and coal tar through this cigarette of analysis of experiments, this is because the coal cinder water content is high, is the product of its at high temperature destructive distillation, its discharge forms and pollutes atmosphere, has caused the waste of fuel simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of baking oven that is equipped with tar recovery system, can improve fuel availability, reduces the pollution to atmosphere.
For solving the problems of the technologies described above, the baking oven of outfit tar recovery system of the present invention, comprise body of heater, the body of heater inner chamber is provided with fire grate, also comprise fuel funnel, be provided with the helical feed pipeline between described fuel funnel and fire grate, in body of heater, the fire grate below is provided with the ventilation duct be communicated with blower fan, be provided with Venturi tube in described ventilation duct, between the throat of described helical feed pipeline and Venturi tube, be provided with the smoke backflow pipe.
After having adopted technique scheme, because Venturi tube can produce negative pressure, the steam that in body of heater, the coal cinder burning produces and the mixed flue gas of coal tar can be back to second-time burning in body of heater through helical feed pipeline, smoke backflow pipe, ventilation duct, thereby can improve fuel availability, reduce the pollution to atmosphere.
The accompanying drawing explanation
Fig. 1 is the structural representation of the baking oven of outfit tar recovery system of the present invention;
Fig. 2 is the partial enlarged drawing that in Fig. 1, Venturi tube and smoke backflow pipe jointing part divide.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Visible as shown in Figure 1, Figure 2, the baking oven of outfit tar recovery system of the present invention, comprise body of heater 1, body of heater 1 inner chamber is provided with fire grate 10, also comprise fuel funnel 2, between described fuel funnel 2 and fire grate 10, be provided with helical feed pipeline 3, the interior fire grate of body of heater 1 10 belows are provided with the ventilation duct 5 be communicated with blower fan 4, be provided with Venturi tube 6 in described ventilation duct 5, between the throat of described helical feed pipeline 3 and Venturi tube 6, be provided with smoke backflow pipe 7.
When the present invention works, in fuel funnel 2, add coal cinder, and be delivered to fire grate through helical feed pipeline 3, described helical feed pipeline 3 ends are connected with power set, and its transporting velocity is adjustable.The entrance of described Venturi tube 6 is arranged on the interior side near blower fan 4 of ventilation duct 5, and diffuser is arranged on the interior side near body of heater 1 of ventilation duct 5.
When the present invention works, coal cinder filled with fuel funnel 2, should be tightly connected between described helical feed pipeline 3 and fuel funnel 2 and body of heater 1, can further prevent that mixed flue gas from leaking.
Heat supply baking oven of the present invention, be not only applicable to take coal cinder as fuel carries out operation, when using charcoal class patch fuel, possesses the function that the flue gases such as carbon monoxide, wood tar is reclaimed to burning yet.
