Abstract

The invention relates to a pot-type calcinator multi-level series fin type cooling device for coke after high-temperature calcination. The device comprises water inlet pipes, water outlet pipes and a plurality of annular cooling water sleeves and is characterized in that the plurality of cooling water sleeves are overlapped and fixedly connected, the outer wall of the inner side of each of the cooling water sleeves is provided with a plurality of fins, the fins on the cooling water sleeves are arranged into lines correspondingly, each line of the fins is located in the same vertical surface, the water inlet pipe and the water outlet pipe are correspondingly arranged at two ends of each of the cooling water sleeves, and except the water outlet pipe at the top cooling water sleeve and the water inlet pipe at the bottom cooling water sleeve, water inlet pipes and water outlet pipes of adjacent cooling water sleeves, which are located at the same end, are communicated through connecting pipes. The device has the advantages that the heat exchange area is large, coke cooling speed after the high-temperature calcination is fast, the discharge temperature is low, the working is reliable, and the like.

Description

technical field [0001] The invention relates to a multi-stage serial fin type 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 raw 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 ...
