Industrial solid waste recycling cyclic utilization device

Abstract

The invention discloses an industrial solid waste recycling cyclic utilization device, and belongs to the technical field of waste treatment. A screening pulverizing element, a mixing impurity removing element, a waste drying element, a pyrolysis furnace, a dust removal device and a power source are mainly included. The mixing impurity removing element is used for adding related reagents into crushed industrial solid waste for pretreatment, and part of organic pollutants in the waste are removed; and in addition, the pyrolysis furnace is utilized for conducting pyrolysis treatment on the pretreated waste, surplus organic matter in the waste is removed, and after pyrolysis gas generated in the pyrolysis process is subjected to purification treatment through the dust removal device, combustible gas and biological oil are obtained, carbon high-quality fuel is generated due to pyrolysis, and the above products can be repeatedly utilized. Recycling treatment of the industrial solid waste isachieved, energy saving and environment protection are achieved, and pollution caused to the environment from the industrial waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to an industrial solid waste resource recycling device. Background technique [0002] Industrial solid waste refers to solid and semi-solid items and substances that have lost their original use value or have not lost their use value but are discarded or abandoned in industrial production activities. It can be divided into general industrial waste (such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, cinder, sulfuric acid slag, waste gypsum, desulfurization ash, carbide slag, salt mud, etc.) and industrial hazardous solid waste, namely hazardous Solid Waste. [0003] With the rapid development of the economy and the improvement of the industrial level, the output of solid solid waste is also increasing year by year, and the content of organic matter in industrial solid waste is high, and a large amount of industrial waste will pollut...

AI Technical Summary

Problems solved by technology

[0004] The existing industrial solid waste resource treatment devices have the following defects: 1) All solid wastes are put into crushing treatment uniformly, which is easy to cause accumulation and reduce the crushing effect, and the particle size of the crushed waste is not uniform, prolonging the subsequent pyrolysis time, The processing efficiency will be low; 2) When drying the crushed waste, the interior of the drying element cannot be cleaned in time, resulting in waste residues and affecting the internal cleaning of the device; Organic pollutants cannot be pretreated, prolonging the pyrolysis time and causing energy waste
