Problems solved by technology

This way of entering the kiln leads to a large amount of air leakage at the kiln head, causing a series of problems such as uncontrollable oxygen content in the kiln, disordered combustion conditions in the kiln, and frequent supplementary combustion in the secondary combustion chamber.
Moreover, due to the different physical properties of different hazardous wastes, it is easy to cause danger when mixed together. There have been many incidents of inner pit explosions and deflagrations in China.
In addition, the "pit type" feeding method is also prone to leachate pollution of groundwater and soil, and environmental pollution such as air pollution caused by the natural discharge of waste gas

Embodiment Construction

[0018] The hazardous waste incineration classification continuous closed feeding system of the present invention will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only illustrative illustrations of the present invention, and are not intended to limit it in any way.

[0019] In order to facilitate the compatibility and safe transportation of various materials, in the present invention, the hazardous waste to be treated is divided into three categories in advance: bulk material, bagged material and liquid material. The calorific value and chemical properties of the same type of material are similar. Among them, bulk materials mainly refer to block or granular solids with a particle size of less than 50ⅹ50ⅹ80mm. The bagged material is used to load special hazardous waste in sealed packaging. This kind of substance is characterized by its relatively active chemical pr...

Abstract

The invention discloses a continuous and sealed feeding system for classified incineration of hazardous waste. The feeding system comprises a bulk material feeding sub-system, a bagged material feeding sub-system and a liquid material feeding sub-system, and the bulk material feeding sub-system, the bagged material feeding sub-system and the liquid material feeding sub-system are used for conveying bulk materials, bagged materials and liquid-state hazardous waste to an incinerating device correspondingly in a continuous and sealed mode. By means of the continuous and sealed feeding system, hazardous waste can be conveniently subjected to heat value detection and chemical proportioning, and therefore process parameters in the incinerating device can be accurately controlled, and stable, safe and efficient operation of the incinerating device is guaranteed.

Description

technical field [0001] The present invention generally relates to the field of hazardous waste incineration treatment, and more specifically relates to a hazardous waste incineration feeding system. Background technique [0002] Hazardous waste (hazardous waste) refers to waste with one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity or infectivity. With the development of industry, the amount of hazardous waste discharged in the industrial production process is increasing, and how to deal with it safely and efficiently is of great significance to environmental safety. [0003] In the existing hazardous waste incineration treatment system, various forms of hazardous waste are usually mixed together and temporarily stored in the pit, and the waste is lifted into the kiln by a grab bucket. This way of entering the kiln leads to a large amount of air leakage at the kiln head, resulting in a series of problems such as uncontrollable o...
