Domestic waste pyrolysis harmless incineration equipment

Abstract

The invention discloses domestic waste pyrolysis harmless incineration equipment. A pyrolysis airflow rotational flow mechanism is arranged and is connected with a nitrogen heater; the nitrogen heaterinjects heated nitrogen in a pyrolysis incineration tank through the pyrolysis airflow rotational flow mechanism to form high temperature nitrogen flow; the nitrogen heater directly injects high temperature gas flow to the incineration tank to effectively improve the incineration heating efficiency; at the same time, the pyrolysis airflow rotational flow mechanism enables high temperature nitrogen flow to downwards spray in a downward spiral manner; and the downward spraying angle of the pyrolysis airflow rotational flow mechanism constantly changes, so that high temperature nitrogen flow flows into garbage waiting for pyrolysis in a garbage can from different angles, in this way, garbage in the incineration tank can be effectively ensured to receive uniform pyrolysis treatment, the treating effect and reliability are improved, and thorough treatment is ensured.

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...

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
