Large-diameter tubular multilayer combustion furnace

Abstract

The invention discloses a large-diameter tubular multilayer combustion furnace. The large-diameter tubular multilayer combustion furnace comprises a furnace wall and a support arranged on one side ofthe furnace wall. A material bucket is arranged at the top of the furnace wall in an embedded manner. One part of the material bucket stretches into the furnace wall, and another part of the materialbucket stretches out. A feeding mechanism is arranged at the stretching-out end of the top of the material bucket. The bottom of the material bucket is arranged in the air cooling wall in the furnacewall in an inserted manner. A first combustion furnace and a second combustion furnace are arranged in the air cooling wall and are arranged in an up-and-down butt joint manner, and filter mechanismsare arranged at the butt joint and the bottom of the second combustion furnace. The bottom of the material bucket penetrates through the air cooling wall and is inserted into the first combustion furnace. According to the large-diameter tubular multilayer combustion furnace, air leakage at an opening can be effectively avoided, combustion temperature is high, use is safe, the purification effect is better, the structure is simple, the use effect is prominent, the defects of previous small furnaces are overcome, and the shaping standard is achieved.

Description

technical field [0001] The invention relates to a combustion furnace, in particular to a large-diameter tubular multi-layer combustion furnace. Background technique [0002] 100 tons of large-scale waste incineration furnaces have been widely used. So far, there are no finalized products at home and abroad for waste incineration furnaces below 100 tons. There are mainly the following reasons, which hinder the development of small waste incineration furnaces; [0003] 1. The composition of the garbage is complex, and the sizes of various types of garbage vary greatly. Commonly used waste furniture and garden garbage are large in size, and the feed port of the small furnace is small, which cannot achieve normal feeding. [0004] 2. Wet garbage accounts for the majority of the garbage. Wet garbage makes it impossible to increase the furnace temperature, and it is easy to produce smoke and strong odor. [0005] 3. Continuous operation cannot be carried out. In the past, the cha...

AI Technical Summary

Problems solved by technology

[0003] 1. The composition of the garbage is complex, and the sizes of various types of garbage vary greatly. Commonly used waste furniture and garden garbage are large in size, and the feed port of the small furnace is small, which cannot realize normal feeding

[0004] 2. Wet garbage accounts for the majority of the garbage. Wet garbage makes the furnace temperature unable to increase, and it is easy to produce smoke and strong odor.

[0005] 3. It is impossible to carry out continuous operation. In the past, the chain transmission conveyor belt was used to feed materials into the furnace, and other methods of feeding materials did not achieve reliable results due to the narrow furnace.

[0006] 4. In the past, lime water was used to treat flue gas, and activated carbon was used to treat flue gas. The cost was high, and the effect of filtering smoke was lost after saturation. The research was terminated because it could not meet the environmental protection requirements.

[0007] 5. The small-scale furnace has a strong odor, the furnace temperature is low, the garbage is not completely burned, and the smoke affects the normal life of nearby residents. Therefore, due to the above reasons, there are no finalized products for small-scale garbage furnaces.
