Embodiment Construction

[0013] exist Figure 1-2 In the embodiment shown: 3 cooling water jackets 4 are superimposed and fixedly connected, a plurality of fins 5 are evenly arranged on the outer wall of the inner side of each cooling water jacket 4, and the upper and lower sides of each fin 5 are oblique edges. , the included angle with the horizontal plane is 80°, the fins 5 on the three cooling water jackets 4 are in a corresponding row, and each row of fins 5 is located on the same vertical plane; Correspondingly, a water inlet pipe 1 and a water outlet pipe 2 are provided. Except for the water outlet pipe 2 located at the uppermost cooling water jacket 4 and the water inlet pipe 1 located at the lowermost cooling water jacket 4, the adjacent cooling water jackets 4 are located at the same end. The water inlet pipe 1 is communicated with the connecting pipe 3 .

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 series-connected fin type cooling device for coke after high temperature calcination in a pot calciner, and belongs to the technical field of solid high temperature material cooling. Background technique [0002] Petroleum coke is a carbon body obtained by thermally cracking the heavy oil remaining after crude oil distillation, and contains some volatiles of uncarbonized hydrocarbon compounds, commonly known as green coke. Green coke can be calcined at high temperature to remove its volatiles and fully carbonized to form calcined petroleum coke. Calcined petroleum coke is mainly used in the production of graphite electrodes, carbon paste products, emery, calcium carbide and other industrial products, and the market demand is huge. At present, the petroleum coke is generally calcined in a tank calciner, and the calcination temperature is about 1300 °C; the calcined petroleum coke is cooled by a single-stage coolin...
