Embodiment 1

[0022] A method for treating waste paint slag by micro-negative pressure pyrolysis, the processing steps are as follows:

[0023] 1) Cleaning: Use reclaimed water to wash the waste paint slag in proportion in the cleaning tank, among which: waste paint slag 100KG, reclaimed water 150KG;

[0024] 2) Dehydration and deodorization, the steps are as follows:

[0025] ① Pour the waste paint slag and reclaimed water into the micro-negative pressure reactor, set the temperature at 350-420°C, heat the micro-negative pressure reactor, and use the heat-conducting oil heating device and stirring device on the inner wall of the reactor to make it fully and evenly heated , and at the same time turn on the stirring device of the micro-negative pressure reactor, so that the waste paint residue is fully and evenly heated;

[0026] ②Set the air pressure in the micro-negative pressure reactor to 700-800 kPa so that the internal air pressure is lower than normal pressure; The gas device extrac...

Abstract

The invention provides a micro negative pressure pyrolysis waste paint slag treatment method, which is characterized by comprising the treatment steps of: 1) cleaning; 2) dewatering and removing odors; 3) grinding, namely grinding the waste paint slag subjected to dewatering and removing odors in a grinding machine; and 4) checking and warehousing, namely recovering the qualified waste paint slag particles after grinding for later use. The method has the advantages that the problem that severe secondary pollution is brought by landfill and burning of waste paint slag in enterprises such as automobiles, household appliances and furniture in each year is solved, and harmful substances and odors in the waste paint slag can be removed, so that the production cost of the enterprise is reduced by 1 / 3, novel profit increase point is increased for the enterprise, and the production efficiency of the enterprise is improved; and meanwhile, 5000 tonnages of waste paint slag can be eliminated in each year, the human health is promoted, the natural ecological environment is improved, the resources are comprehensively utilized, waste materials are changed into valuables, the natural ecological environment can be improved, the environmental pollution is avoided, and the resource advantages are changed into economic advantages; and moreover, the implementation of the national ecological environment construction and the strategy of sustainable development is promoted, and the method facilitates the nation and the people.

Description

technical field [0001] The invention relates to an industrial waste treatment method, in particular to a micro-negative pressure pyrolysis waste paint slag treatment method. Background technique [0002] With the development of industries such as automobiles and home appliances, there are more and more industrial wastes. How to effectively deal with these industrial wastes has become an urgent matter for various manufacturers, especially the proper disposal of waste paint slag; after market research, Anhui's Automobile companies produce about 1,000 tons of waste paint slag annually, household appliance companies produce about 1,500 tons of waste paint slag, and furniture companies produce about 1,000 tons of waste paint slag. Incineration, the resulting secondary pollution is a very serious problem, and the harmful substances and peculiar smells in the waste paint slag are not easy to remove, etc., which we urgently need to solve. Contents of the invention [0003] In ord...
