Hazardous waste incinerator with dry cooling slag discharging mechanism

Abstract

The invention relates to the technical field of hazardous waste disposal, in particular to a hazardous waste incinerator with a dry cooling slag discharging mechanism. The hazardous waste incineratorcomprises a rotary kiln, a secondary combustion chamber and a slag discharging mechanism which are arranged in series; the slag discharging mechanism comprises ash slag cooling equipment and a filtering device; the ash slag cooling equipment comprises a shell and a roller which are coaxially arranged, one axial end of the roller is connected with a driving motor through a connecting shaft, and rotation of the roller relative to the shell is achieved; a circular-ring-shaped water pipe is coaxially arranged in one end of the roller; and a cooling water pipe is coaxially arranged in the roller and symmetrically provided with water pipe fins arranged along a pipe body. According to the hazardous waste incinerator with the dry cooling slag discharging mechanism, reverse-flow indirect contact heat exchange is achieved, and the condition that in the prior art, water source pollution is caused by direct contact heat exchange is changed; and meanwhile, roller fins and the water pipe fins can significantly increase the heat transfer area and can better conduct ash slag heat, the roller fins and the water pipe fins are arranged regularly and achieve a guiding effect on ash slag discharging, and the energy efficiency of the disposal system is improved.

Description

Technical field [0001] The invention relates to the technical field of hazardous waste disposal, in particular to a hazardous waste incinerator with a dry cooling and slagging mechanism. Background technique [0002] Hazardous waste is one of the important pollution sources that endanger the human ecological environment and human health. In recent years, with the development of society, the amount of its generation has also increased significantly. If it is not effectively disposed of, it is discharged at will, not only to the water environment, air environment and soil The serious impact and damage caused by the environment will also pose a direct threat to personal safety and health. Therefore, the harmless disposal of hazardous waste is a social issue that must be paid attention to. [0003] Hazardous waste incineration is a typical technical solution for hazardous waste treatment and disposal. It is also the most effective and thorough disposal method for combustible solid wast...

AI Technical Summary

Problems solved by technology

Although the cooling efficiency is relatively high, due to the use of cooling water for contact cooling, the heat of ash and slag has not been effectively utilized, and waste water will be generated during the slag discharge process, which increases the difficulty and load of water treatment. , and the fluctuation of the water surface during the feeding process will inevitably produce unorganized waste gas, which will cause energy loss and double pollution of waste water and waste gas, resulting in environmental pollution

In the situation of increasingly stringent environmental protection standards, the heat consumption load and production cost of the project have been virtually increased
