The invention relates to a multi-stage parallel cooling device for high-temperature calcined coke of a pot-type calcining furnace. The multi-stage parallel cooling device comprises a water inlet system and annular water cooling sleeves, and is characterized in that a plurality of the water cooling sleeves are superposed and fixedly connected; the water inlet system comprises a water inlet header tube which is communicated with a water supply system and a plurality of water inlet branch tubes; a regulating valve is arranged on each water inlet branch tube; a water outlet tube is arranged on one end of each water cooling sleeve, and the other end of the water cooling sleeve is communicated with a water inlet branch tube; and the water outlet tube and the water inlet branch tube are arranged on the two ends of the water cooling sleeve. According to the multi-stage parallel cooling device, the high-temperature calcined coke provided by the invention has the advantages of quick cooling speed, controllable cooling water amount, low discharging temperature, high working reliability and the like.
Description
technical field [0001] The invention relates to a multi-stage parallel cooling device for high-temperature calcined coke in a tank type calciner, which belongs to the technical field of solid high-temperature material cooling. Background technique [0002] Petroleum coke is a charcoal material obtained by thermal cracking of the heavy oil left after crude oil distillation. It contains some volatile components of uncarbonized hydrocarbons, commonly known as green coke. Green coke can be calcined at high temperature to remove its volatile content and be completely carbonized to form calcined petroleum coke. Calcined petroleum coke is mainly used in the production of industrial products such as graphite electrodes, carbon paste products, corundum, and calcium carbide, and the market demand is great. At present, the petroleum coke is generally calcined in a pot calciner, and the calcining temperature is about 1300°C; the calcined petroleum coke is cooled by a single-stage cooli...
