Abstract

The invention provides a coking desulfurization liquid waste sulfur treatment device, and belongs to the technical field of sulfur treatment. The coking desulfurization liquid waste sulfur treatment device comprises an oxidizing pot, a first conveying pump, a centrifugal machine, a mixing tank, a second conveying pump, a sulfur melting pot, a sulfur flaker and a chain scraper conveyor, wherein theoxidizing pot communicates with the centrifugal machine through a communicating pipeline, the centrifugal machine communicates with the mixing tank through a communicating pipeline, the mixing tank communicates with the sulfur melting pot through a communicating pipeline, the sulfur melting pot communicates with the sulfur flaker through a communicating pipeline, and the sulfur flaker communicates with the chain scraper conveyor through a communicating pipeline. The coking desulfurization liquid waste sulfur treatment device has the advantage that low-quality sulfur generated in an oxidationprocess of ammonium thiosulfate is conveyed to the sulfur melting pot to be subjected to sulfur melting treatment after being mixed with desulfurization liquid waste, generated high-quality sulfur issold after being treated through the sulfur flaker, and accordingly the problem that the original low-quality sulfur is hard to sell is solved. The coking desulfurization liquid waste sulfur treatmentdevice has the advantages of less investment, simple structure, convenience in use, good quality of sulfur products and the like.

Description

technical field [0001] The invention belongs to the technical field of sulfur treatment, and in particular provides a sulfur treatment device for coking desulfurization waste liquid. Background technique [0002] At present, many coking enterprises in China generally adopt the method of extracting secondary salt step by step to treat the desulfurization waste liquid generated by the desulfurization system. In order not to produce mixed salts that are not conducive to sales, in the process of extracting auxiliary salts, it is necessary to oxidize the desulfurization waste liquid, oxidize the ammonium thiosulfate in the desulfurization waste liquid into ammonium sulfate, and finally produce ammonium sulfate for further processing. Sales. However, during the oxidation of ammonium thiosulfate to ammonium sulfate, sulfur by-products of poor quality will be produced, making it difficult to sell them directly. The sulfur by-products of many enterprises often pile up in large quan...
