Abstract

The invention discloses a leather waste vaporizing combustion and heat recovery system, and an operation method thereof. The operation method comprises the steps that leather waste is subjected to high-temperature cyclone vaporizing in a section of the vaporizing combustion and heat recovery system; after gas is separated from liquid ash, the gas enters a second section and is supplemented with excessive air, so that the gas is combusted completely; flue gas generated after the gas is combusted completely enters waste heat recovery equipment, so that waste heat is recovered; and finally, the flue gas is discharged after purification and dust removal. The system is simple in structure and high in combustion intensity, can reduce pollutants effectively, and achieves clean recycling of the leather waste.

Description

【Technical field】

[0001] The invention relates to a gasification combustion and heat recovery system of leather waste and an operation method thereof. 【Background technique】

[0002] In the leather industry, a large amount of dander, broken skin and leftovers will be produced. In recent years, my country has become the world's largest leather producer. According to statistics, there were more than 200 PU leather manufacturers in my country in 2006, and about 1.4 million tons of leather waste solid waste can be generated every year. If these leather wastes are not handled properly, they will pollute the environment. Some leathers also contain a certain amount of Cr 3+ , and the pollution it causes is even more serious if it is not handled properly. On the other hand, leather waste usually has a certain calorific value, and some leather waste has the value of reuse, which has led to the research on the utilization and resource utilization of leather waste. At present, the...
