Abstract

The present invention relates to the technical field of pyromelting processing of hazardous waste, specifically a deep drying system for high-temperature melting of waste sludge, including several drying furnaces arranged in a row and flue gas collection equipment. The flue gas collection device includes a collection body, The exhaust box, the exhaust pipe, the first collection pipe, the second collection pipe and the fourth collection pipe, along the axial direction of the first collection pipe, the first collection pipe, the second collection pipe, the third collection pipe and the fourth collection pipe The diameter is gradually reduced, and the first collecting pipe, the second collecting pipe, the third collecting pipe and the fourth collecting pipe are all provided with collecting buckets connected through connecting pipes. The collecting bucket is provided with rotating cleaning scrapers. The top is equipped with a drive assembly that drives the cleaning scraper to rotate and a valve assembly that controls the connection of the connecting pipe. A partition assembly is installed at the connection between the collecting bucket and the drying furnace. When the cleaning scraper rotates, the partition assembly separates the collecting bucket from the drying furnace. connectivity.

Description

technical field [0001] The invention relates to the technical field of pyro-melting treatment and processing of hazardous waste, in particular to a deep drying system for high-temperature melting of waste sludge. Background technique [0002] The pyro-melting processing technology of hazardous waste is to first crush and sieve the raw materials according to different components, then make them into a certain particle size by a granulator, send them to a deep drying furnace for deep drying, and finally send the massive sintered materials to a reduction smelting furnace for melting. The sintered powder is put into the smelting furnace to be smelted after being dried by brick making. [0003] When the material is deeply dried, due to the instability of the material and the fluctuation of temperature, the emission amplitude of nitrogen oxides is large, and it will be accompanied by a large amount of dust. [0004] In the patent with the patent application number CN201911134747....
