A multi-level auxiliary heating type garbage disposal equipment

Abstract

The invention discloses multilayer auxiliary heating type garbage disposal equipment, which comprises a furnace body and a heat supply device, wherein the furnace body comprises an upper furnace body and a lower furnace body; the upper furnace body is provided with an upper clamping cavity; the upper clamping cavity is provided with an exhaust opening; the lower furnace body is provided with a lower clamping cavity; the top of the upper furnace body is provided with a feeding opening; a first auxiliary heating pipeline is arranged in the upper furnace body, and is provided with an air inlet end and an air outlet end; the air outlet end of the first auxiliary heating pipeline communicates with the upper clamping cavity; an air inlet pipe rack is arranged at the bottom of the furnace cavity of the lower furnace body; a second auxiliary heating pipeline is arranged above the air inlet pipe rack, and is provided with an air inlet end and an exhaust end; the air inlet end of the second auxiliary heating pipeline communicates with the lower clamping cavity; the air outlet end of the second auxiliary heating pipeline communicates with the first auxiliary heating pipeline; the heat supply device communicates with the lower clamping cavity and the first auxiliary heating pipeline; a first valve is arranged between the heat supply device and the lower cavity body; a second valve is arranged between the heat supply device and the first auxiliary heating pipeline. The multilayer auxiliary heating type garbage disposal equipment can effectively ensure the sustained combustion of garbage in the combustion layer.

Description

technical field [0001] The invention relates to the technical field of garbage disposal equipment, in particular to a multi-level auxiliary heating type garbage disposal equipment. Background technique [0002] With the continuous growth of the global economy and the acceleration of urbanization, the generation of domestic waste has become an increasingly serious environmental problem. The continuous increase of municipal waste production and the environmental pollution caused by it has become a common problem faced by all countries. Among them, the waste pyrolysis gasification incinerator is the most commonly used treatment equipment for pollution-free waste treatment. Its working principle is to use the bottom waste to burn to provide heat for the entire furnace body. Since the combustion air flow is upward, the waste forms a drying dewatering layer, a pyrolysis gasification layer, a reduction carbonization layer and a The combustion layers are closely connected, and gra...

Problems solved by technology

[0003] Then, in the existing garbage pyrolysis and gasification incinerators, the heat in the furnace depends entirely on the garbage in the combustion layer for heating. Once the garbage above the combustion layer absorbs too much heat, the heat generated by the burning of garbage in the combustion layer will be reduced. When the demand cannot be supplied, the garbage in the furnace will not be able to be dried and pyrolyzed normally, and even the burning layer will be extinguished, making it impossible to continue burning. It needs to be improved urgently.
