Incineration device for treating multi-variety and multi-phase wastes

Abstract

The invention discloses an incineration device for treating multi-variety and multi-phase wastes, belonging to the field of waste processing equipment. The incineration device comprises a furnace body of an incineration furnace; a feeding opening is arranged at the upper part of the furnace body and a discharging channel is arranged at the lower part of the furnace body; a discharging opening is arranged at the tail end; the feeding opening is provided with a high-temperature air opening and at least two stages of step-shaped material stoking platforms are arranged below the feeding opening in the furnace body; the discharging channel is arranged below the final stage of the material stoking platform; and each stage of the material stoking platform is provided with a material pushing device capable of pushing materials to drop into the next stage of the material stoking platform or the discharging channel. The invention provides the incineration device which can simultaneously treat three types or more types of the multi-variety and multi-phase wastes (industrial waste residue, waste liquid, municipal solid wastes and sludge of sewage plants), and has the advantages of reasonable flow and structure and strong adaptability, and can finish the integrated treatment.

Description

technical field [0001] The invention belongs to the field of waste treatment equipment. Background technique [0002] With the development of the economy and the improvement of people's living standards, the scale of various industrial wastes and domestic wastes is increasing day by day. The resulting pollution has become one of the global public hazards. How to deal with these wastes has become an important topic and issue at present. problem. Some existing waste treatment processes use cement kilns to directly incinerate various wastes to treat wastes: At present, most of the process devices for waste disposal in cement kilns are used to dispose of a single type of waste, and a few can dispose of multiple types of waste. The process equipment of the waste is also disposed separately, mainly adopting the method of dispersing and directly adding waste in the cement calcining system. This method has the problems of small disposal volume, decentralized setting, complex system...

Some existing waste treatment processes use cement kilns to directly incinerate various wastes to treat wastes: At present, most of the process devices for waste disposal in cement kilns are used to dispose of a single type of waste, and a few can dispose of multiple types of waste. The process equipment of the waste is also disposed separately, mainly adopting the method of dispersing and directly adding waste in the cement calcining system. This method has the problems of small disposal volume, decentralized setting, complex system, and difficult adjustment of incineration temperature, and the problem of direct incineration The method will affect the incineration of the original incineration equipment for cement production, and further adversely affect the cement production

In addition, if multi-phase and multi-species wastes are disposed of in a centralized manner, due to the different chemical components, physical properties, and incineration and decomposition conditions of the wastes, and a certain scale of disposal is also required, during the process of waste disposal and It cannot affect the normal production of cement calcination, and the conventional cement production system is difficult to adapt to this condition, because for a single disposal of a certain waste, the material performance is relatively simple, and the process system and equipment are also more targeted. When there are many and complex phases, the technical difficulty will increase significantly
