Problems solved by technology
There are still many problems in the existing method: First, since the incineration area and the drying area are usually not hindered to facilitate the transportation of garbage, the flame in the incineration area often rolls up the garbage in the drying area, causing the garbage in the drying area to explode on the conveyor belt. This reduces the heat energy utilization rate of waste incineration and reduces the economic benefits of waste incineration; secondly, when the waste enters the pre-drying area from the feeding area, it is often dumped by vehicles or manually, and the waste is easy to be dumped. After entering the conveyor belt, the whole piles up on the conveyor belt, which is not conducive to the effective drying of the garbage; finally, when the garbage is baked on the conveyor belt, the surface moisture of the garbage in contact with the hot air tends to evaporate very quickly, but it is not compatible with the hot air. The moisture in the direct contact part such as the part of the garbage attached to the surface of the conveyor belt is not easy to dissipate, so the water content is still very large. A large amount of heat energy, and a large amount of flue gas is added after incineration, resulting in an increase in the overall emission of flue gas, leading to other adverse consequences such as environmental pollution

Embodiment Construction
[0015] A drying oven, such as figure 1 , figure 2 and Figure 5 As shown, it includes a furnace body 10 and an air duct, and the drying furnace also includes a conveyor belt 20 for transporting garbage, and the conveyor belt 20 is located inside the furnace body 10, and the conveyor belt 20 has a ventilation structure.
[0016] As a specific embodiment of the present invention, the conveyor belt 20 is composed of a plurality of independent and closed conveyor strips 21, and the conveyor strips 21 are parallel to each other in its conveying direction, as figure 2 And as in 5, the effect of convective heat exchange is achieved by relying on the gaps between the conveying bars 21.
[0017] Further, such as Figure 1-5 , the conveying strips 21 are in the shape of a closed chain, and the distances between adjacent conveying strips 21 are equal. The drying furnace also includes a driving roller 30 for driving the conveyor belt 20 to move. There are two driving rollers 30, and...

The invention belongs to the field of garbage prebaking, in particular to a baking furnace. The baking furnace comprises a furnace body, an air flue and a conveyer belt for conveying garbage; and the conveyer belt is arranged in the furnace body and is provided with a ventilating structure. As the conveyer belt is provided with the ventilating structure, after the garbage enters a prebaking region and when the garbage is conveyed by the conveyer belt, part of garbage exposed on the conveyer belt can be effectively baked, and the interior of the garbage also has very good baking effect after undergoing the convection heat transfer of the ventilating structure, thereby effectively reducing the moisture content of the garbage and increasing the heat value of the garbage.
Description
technical field [0001] The invention belongs to the field of garbage pre-drying, and in particular relates to a drying furnace. Background technique [0002] Garbage is solid waste generated in human daily life and production. Due to the large amount of discharge and complex and diverse components, it brings difficulties to treatment and utilization. If it cannot be disposed of in time or improperly disposed of, it will pollute the environment and affect environmental sanitation. Garbage disposal is to quickly remove garbage, and conduct harmless treatment, and finally make reasonable use of it. The garbage disposal methods widely used today are sanitary landfill, high temperature composting and incineration. Garbage incineration is a municipal waste treatment method widely used in countries all over the world. Large-scale waste incineration treatment systems equipped with heat recovery and utilization devices are gradually becoming the mainstream of incineration treatment ...
