Thermal gasification recovery and treatment method for cladded metal containing metal film paster and device therefor

Abstract

Disclosed is thermal gasification recovery processing method for a paster containing metallic membrane with metal coating, which belongs to the field of destroying the solid waste or converting the solid waste to useful or harmless materials, comprising the steps of: A, crushing the materials; B, thermal gasification process for materials processed by step A in the presence of catalyst and reducer at the temperature of 130 to 600 DEG C., wherein the catalyst is selected form silicon dioxides and aluminas and the reducer is selected form alkali inorganic reducers; C, condensing and water cleaning for the gas from the materials processed by thermal gasification, separating the combustible gas and liquid fuel oil, and collecting, wherein the condensing temperature is 35 to 120 DEG C.; D, collecting metal and carbon black in discharge hole from step B. A thermal gasification recovery processing device is also disclosed. The recovery process is provided with high economy in low cost, especially, the process is beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of destroying solid waste or converting solid waste into useful or harmless things, and in particular relates to a thermal gasification recovery treatment method and equipment for a wrapped metal-containing metal film patch. Background technique [0002] With the increasing scarcity of human available resources, the recycling and recycling of resources has been paid more and more attention by people. For example, for metal-containing film patches with sheathing, such as waste electric wires, because they contain high-value metals such as copper, aluminum, gold, silver, tin, etc., these waste metal-containing film patches with sheathing will be recycled and extracted expensive metals. At present, there are mainly the following two types of recycling processes and equipment for these waste metal-containing film patches with sheathing. The first is to use the incineration process, that is, open-air incinerati...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, the equipment for realizing the resource recycling process has a single function, and it is impossible to comprehensively utilize various renewable resources

This is an important reason why a large number of waste materials cannot be recycled and comprehensively utilized and are abandoned, causing environmental damage.

Due to the lack of multi-purpose and comprehensive recycling processes and equipment, these wastes are piled up day by day because they cannot be processed in time, occupying a large amount of space and environment on which we live, or due to technical obstacles and unreasonable process design, making the equipment The comprehensive utilization rate is low, which causes a serious waste of other resources while recycling one resource, not only the raw materials and other resources cannot be regenerated and recycled, but also will aggravate the secondary pollution of the environment
