Treatment device and treatment method of metal package surface hazardous wastes

Abstract

The invention discloses a treatment device of metal package surface hazardous wastes. The device comprises a base, a hot cleaning furnace, a heat exchanger, an SCR denitration reaction tower, an active carbon spraying system, a wet method deacidification tower, a cloth bag dust remover and an induced draft fan are arranged at the upper end of the base in sequence, a heat exchange condenser is arranged at the upper end of the SCR denitration reaction tower, the hot cleaning furnace comprises a first combustion chamber and a second combustion chamber arranged on the first combustion chamber, thefirst combustion chamber and the second combustion chamber are arranged on the base, the second combustion chamber is connected with the heat exchanger through a first channel pipe, the heat exchanger is connected with the SCR denitration reaction tower through a second channel pipe, and the SCR denitration reaction tower is connected with the active carbon spraying system through a third channelpipe. The device is reasonable in design, through the pyrolysis principle, the hazardous wastes tainted on the surface of a metal package are stripped and treated effectively, recycling of old metalpackage can be achieved, and the discharging and running cost of the pollutant can be reduced.

Description

technical field [0001] The invention relates to the technical field of processing hazardous wastes on the surface of metal packages, in particular to a processing device and a processing method for hazardous wastes on the surfaces of metal packages. Background technique [0002] With the increasing awareness of environmental protection, people's awareness of recycling waste is increasing. At present, recycling barrel-shaped waste metal packaging can not only reduce the waste of resources to a large extent, but also greatly reduce the waste of resources. To greatly reduce the pollution to the environment, when recycling barrel-shaped waste metal packaging, it is necessary to treat the pollutants on its surface. The pollutants on the surface mainly include waste paint, waste resin, waste oil, traditional The treatment methods mainly include cleaning (washing), shot blasting and crushing, which not only have high operating costs, but also cause secondary pollution to the social...

Problems solved by technology

[0002] With the increasing awareness of environmental protection, people's awareness of recycling waste is increasing. At present, recycling barrel-shaped waste metal packaging can not only reduce the waste of resources to a large extent, but also quickly To reduce environmental pollution to a large extent, when recycling barrel-shaped waste metal packaging, it is necessary to treat the pollutants on its surface. The pollutants on the surface mainly include waste paint, waste resin, waste engine oil, traditional The processing methods mainly include cleaning (washing), shot blasting, and crushing, which not only has high operating costs, but also causes secondary pollution to the social environment

[0003] With the continuous improvement of the current actual demand, the traditional treatment methods can no longer meet the actual needs of the current recycling work. Therefore, we have designed a treatment device and treatment method for hazardous waste on the surface of metal packaging to solve the above problems.
