Abstract

The invention discloses a dust removal, desulfurization, water collection and heat raising system for water coke quenching, comprising: a coke quenching tower (1), a sprayer, a coke quenching vehicle (4), a water collection tank (5), dust removal and desulfurization settlement Pool (6), replenishing water and dosing tank (7), high-efficiency heat exchanger (10) and circulating heating water tank (11); a sprayer is arranged in the coke quenching tower (1), and the bottom of the coke quenching tower (1) is Coke quenching car (4), a sump (5) is provided under the coke quenching car (4), and the sump (5) is connected with the dedusting and desulfurization settling tank (6). Medicine tank, dedusting and desulfurization settling tank (6) are connected with high-efficiency heat exchanger (10), and high-efficiency heat exchanger (10) is bidirectionally connected with circulating heating water tank (11), and high-efficiency heat exchanger (10) is also connected with shower. The coke quenching water in the invention is recycled, and the coke slag and gypsum discharged from the settling tank can be used after being dehydrated.

Description

technical field [0001] The invention relates to a dust removal, desulfurization, water collection and heat raising system for water coke quenching. Background technique [0002] Coke quenching is an important process in coking plants. Water quenching is a coke quenching method commonly used in small and medium-sized coke ovens. Compared with dry coke quenching, it has less investment and lower operation and maintenance costs. In the process of water coke quenching, the generated water vapor carries a large amount of coke dust, sulfide, and nitrogen oxides, and consumes hundreds of tons or even thousands of tons of water every day, resulting in a serious waste of heat energy. At the same time, it also brings dust, sulfur Compounds, nitrogen oxides and other air pollution. Contents of the invention [0003] In order to solve the technical problems of heat energy waste and air pollution in the water coke quenching process, the present invention provides a water coke quenchin...
