Problems solved by technology

[0004] However, this patent only discloses the separation of hazardous waste, but this patent does not take into account how the sent hazardous waste is concentrated at the central high-temperature place of the incineration equipment for combustion, and does not take into account that a large amount of hazardous waste is input into the incineration equipment Finally, the incineration space becomes smaller, how to quickly expand the space for rapid incineration of hazardous waste

Embodiment

[0056] like Figure 1 to Figure 10 As shown, a hazardous waste incineration fly ash self-cleaning device includes pretreatment and feeding equipment, incineration equipment, waste heat boiler equipment, quenching device and deacidification and dust removal equipment. The incineration equipment includes a primary combustion chamber and a secondary combustion chamber. chamber, the primary combustion chamber includes:

[0057] Combustion chamber body 1, the combustion chamber body 1 is provided with a combustion space, and the combustion chamber body 1 is connected with the feeding device;

[0058] A material removal mechanism 2, the material removal mechanism 2 is installed in the lower part of the combustion space in the combustion chamber body 1, the material removal mechanism 2 is used to disperse the hazardous waste input by the feeding device, and the material removal mechanism 2 includes A material removal assembly 21 and a drive assembly 22, the removal assembly 21 is in...

Embodiment approach

[0083] As a preferred embodiment, the fly ash self-cleaning mechanism 4 includes:

[0084] A combustion-supporting passage 41, the combustion-supporting passage 41 is arranged in the side wall of the combustion chamber body 1, a mixture of a combustion-supporting agent and air circulates in the combustion-supporting passage 41, and the outlet of the combustion-supporting passage 41 is located in the auxiliary combustion zone 32 ;as well as

[0085] Movable sealing plate 42, described movable sealing plate 42 is installed on the described fire grate 3, this movable sealing plate 42 switches the outlet of described combustion-supporting channel 41 with the lifting of described fire grate 3;

[0086] The ash collection bin 43, the ash collection bin 43 is arranged directly above the dismantling mechanism 2, the ash collection bin 43 communicates with the combustion-supporting channel 41 through a communication branch pipe 44, and the communication branch pipe 44 is arranged obliq...

Abstract

The invention relates to the technical field of incineration treatment and processing of hazardous waste, specifically a self-cleaning device for incineration fly ash of hazardous waste, including pretreatment and feeding equipment, incineration equipment, waste heat boiler equipment, rapid cooling device, deacidification and dust removal equipment, and incineration equipment It includes the primary combustion chamber and the secondary combustion chamber. The primary combustion chamber includes the combustion chamber body, the unloading mechanism, the grate and the fly ash self-cleaning mechanism. The unloading mechanism cooperates with the fly ash self-cleaning mechanism. When dismantling hazardous waste, the ash collection bin in the fly ash self-cleaning mechanism is driven to open, and the fly ash caused during the disassembly process is collected by the ash collection bin, and diverted to the auxiliary combustion area to cooperate with the auxiliary combustion area The setting makes the fly ash re-deposit on the grate, which solves the technical problem of flying ash during the combustion process of the split.

Description

technical field [0001] The invention relates to the technical field of incineration treatment and processing of hazardous waste, in particular to a self-cleaning device for incineration fly ash of hazardous waste. Background technique [0002] Hazardous waste incineration technology based on combustion equipment has become one of the hazardous waste disposal technologies supported by my country's environmental policy because of its high-strength destructiveness to toxic pollutants and wide adaptability to materials. The current technology of incineration equipment Hazardous wastes are crushed before disposal. Although the incineration efficiency can be improved to a certain extent, due to the reduction in volume after crushing, the accumulation density of the waste is relatively high. If the feeding interval is not well controlled, it will lead to The interior of the garbage cannot be incinerated and penetrated, causing the reverse effect. [0003] In the patent application n...
