Description

technical field [0001] The invention relates to the field of environmental chemical engineering, in particular to a multi-combination auger catalytic cracking regeneration waste solidified organic matter system. Background technique [0002] Environmental pollution is a major problem in countries all over the world. Around this major problem, in recent years, many scientific research institutions, colleges and production units have manufactured and developed a large number of production processes and production equipment. Usually it is furnace type, tube type, rotary drum type, single screw type, multiple degradation method, biological method, incineration method, pyrolysis method, etc. This kind of equipment not only has certain safety problems, but also has serious secondary pollution due to the production process technology, large equipment investment, large equipment loss, large workshop space occupation, small processing capacity, single variety, no depth of products, a...

AI Technical Summary

Problems solved by technology

This kind of equipment not only has certain safety problems, but also has serious secondary pollution due to the production process technology, large equipment investment, large equipment loss, large workshop space occupation, small processing capacity, single variety, no depth of products, and some of them are not up to standard. Although some equipment uses molten salt as a heat conductor, due to the temperature limit of the molten salt pump, the temperature cannot be raised to a certain temperature, resulting in incomplete thermal cracking and a large amount of energy loss.

[0003] 2. The drum type and furnace type are intermittent slag discharge dust and harmful gases that directly threaten human health. The equipment consumes a lot of energy, the output is small, the product is single, and the product is poor-commonly known as crude oil and crude oil, and the dust in the residue is sent out And the gas is very harmful to the human body and the environment, the carbonization and aging of the equipment is serious, and the direct contact with the flame burning

The coking of the furnace body is serious, resulting in a series of changes, and even partial equipment may cause leakage, which poses a major safety hazard

[0004] 3. Single-screw propulsion heating (molten salt) cracking relies on the molten salt liquid being extracted and circulated by the molten salt pump to conduct heat. Once the temperature of the molten salt is too high and the molten salt pump is limited by the temperature, some materials have high heavy fractions. Can not achieve the purpose of all pyrolysis distillation

The residual residue contains high heavy oil colloids, which cannot meet the discharge requirements, and the equipment requires limited raw materials and other factors

[0005] 4. Biodegradation technology is a new product developed in recent years. This technology takes a long time and occupies a large area. A large amount of recycled resources are wasted and cannot be recycled. Gases such as carbon monoxide generated during the reaction process are directly entered The atmosphere, and some organic substances are not completely reacted, and still exist in raw materials and wastes. Heavy metals cannot be destroyed and removed, and various salts are produced.

[0006] 5. Incineration not only wastes valuable recycling resources, but also produces dioxin, carbon dioxide, sulfur tetrachloride dust and other substances into the atmosphere, causing serious secondary pollution
