A kind of domestic garbage pyrolysis harmless incineration equipment

Abstract

The invention discloses a pyrolysis and harmless incineration device for domestic garbage. The invention provides a pyrolysis air flow swirl mechanism, which is connected with a nitrogen heater, and the nitrogen heater passes the heated nitrogen through the The pyrolysis gas flow swirling mechanism injects high-temperature nitrogen gas flow into the pyrolysis incineration tank, and uses the nitrogen heater to directly put the high-temperature gas flow into the incineration tank, which can effectively improve the incineration heating efficiency. At the same time, the pyrolysis gas flow of the present invention The flow mechanism can make the high-temperature nitrogen gas flow spray downward in a downward spiral manner, and the angle of the downward injection of the pyrolysis gas flow swirl mechanism is constantly changing, so as to improve the high-temperature nitrogen gas flow from different angles. In this way, it can effectively ensure the uniform pyrolysis treatment of the garbage in the incineration tank, improve the treatment effect and reliability, and ensure the thoroughness of the treatment.

Description

technical field [0001] Specifically, the invention relates to a harmless pyrolysis incineration equipment for domestic garbage, and relates to the related field of incineration equipment. Background technique [0002] At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting, and the way of landfill will cause great harm to the soil, etc., and the filling area is very large, while the way of incineration will cause great harm to the air environment. There is a great adverse effect. For this, there is currently a way of pyrolysis for garbage disposal. The pyrolysis method of garbage disposal is essentially to place the garbage in a completely sealed furnace and heat the temperature in the furnace to 450 to 750°C. Carrying out pyrolysis treatment under high temperature and anoxic conditions can realize the treatment of garbage very well, and the coke produced in this way can be reused. There...

AI Technical Summary

Problems solved by technology

However, the current garbage pyrolysis method generally only uses heating to heat the incinerator or incinerator. Due to the large size of the incinerator or incinerator, this leads to low heating efficiency, long heating time, and is difficult to conduct to The central position of the tank or furnace body makes it difficult to effectively complete the internal garbage pyrolysis, which affects the treatment efficiency and reliability
