Garbage continuous cracking furnace

Abstract

The invention discloses a garbage continuous cracking furnace and aims to provide the garbage continuous cracking furnace which is relatively low in operation cost, good in purification effect, relatively low in energy consumption, free from pollution emission, high in working efficiency, relatively large in treatment amount and wide in application range. The garbage continuous cracking furnace comprises a furnace body, a first gate valve (11) and a second gate valve (14), wherein the first gate valve (11) and the second gate valve (14) divide the furnace body into a cracking cabin (26), a middle cabin (13) and a feeding cabin (16); a side wall at the cracking cabin (26) comprises an inner liner (8), a heat-preserving layer (9) and an outer liner (10) which are sequentially arranged from inside to outside; a heater (24) is arranged in the heat-preserving layer (9); a slag discharging pipe (23) is arranged on the lower part of the cracking cabin (26); a cracking cabin air outlet (27) is formed in the side wall at the cracking cabin (26); and a middle cabin air outlet (28) is formed in the side wall at the middle cabin (13).

Description

technical field [0001] The invention relates to a garbage continuous cracking furnace. Background technique [0002] The more typical garbage disposal equipment in the past mainly includes the following types: 1. High temperature incineration equipment. Its volume and weight are relatively large, and the shape of the treated garbage is obviously destroyed; it is suitable for more waste types and large-scale applications; it operates stably, and has good disinfection and pollutant removal effects. However, the construction and operation costs of this equipment are extremely high, energy consumption is large, and the equipment is poorly sealed, causing serious air pollution. When using this equipment for garbage disposal, it is easy to produce harmful gases such as dioxins, and the emission of greenhouse gases is large; 2. High-pressure steam Sterilization equipment. The equipment has relatively low investment, low operating costs, easy detection, low risk of residues, good ...

AI Technical Summary

Problems solved by technology

However, the volume of the equipment is small and the processing capacity is limited, the disinfection effect is poor, and the pressure release and exhaust exhaust pollute the air, which is easy to produce odorous gas

Therefore, many manufacturers or companies have made improvements to these problems. For example, the Chinese patent No. ZL2011103750241 discloses a garbage cracking furnace, which includes a cracking furnace body, a cover plate, a motor, and a speed changer. The upper opening of the cracking furnace body is The place is the feeding port, the cover plate is sealed with the feeding port, the upper part of the cracking furnace body is provided with a gas outlet, and the cracking furnace body includes an inner tank and an outer tank, and the inner tank and the outer tank The tank is provided with an insulation layer, the insulation layer is provided with a heater, and the lower part of the furnace body is provided with a slag discharge pipe. This patent is to crack the garbage in a fully enclosed, negative pressure, and oxygen-poor state, which can Low consumption, low processing cost, no greenhouse gas generation, and thorough disinfection, sterilization and decomposition, but in the actual application process of this patent, intermittent feeding is required, the work efficiency is low, the processing capacity is relatively small, and it cannot be applied to large-scale garbage processing station
