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
The present invention relates to the finned refrigerating unit of a kind of can-type calcine furnace high temperature calcined coke plural serial stage, belong to solid high-temperature material cooling technology field.
Background technology
Refinery coke is the charcoal body thing that mink cell focus remaining after crude distillation is obtained through hot tearing again, contains some not fugitive constituents of the carbon hydrocarbon compound of carbonization, is commonly called as green coke.Green coke can be removed its fugitive constituent by high-temperature calcination, and charing forms calcined petroleum coke completely.Calcined petroleum coke is mainly for the production of Industrial products such as Graphite Electrodes, charcoal paste, silicon carbide, calcium carbides, and the market requirement is very large.At present, generally adopt can-type calcine furnace to calcine refinery coke, calcining temperature is 1300 DEG C of left and right; Refinery coke after calcining is undertaken cooling by single stage cooling water jacket, then by blow-off valve discharging.Single stage cooling water jacket is generally double-layer plate welded construction, and inner layer steel plate surrounds the passage of a high-temperature material; The annular gap water cavity that forms sealing between inside and outside layer steel plate is cooling-water duct.When high temperature refinery coke is when the single stage cooling water jacket, heat is conducted to the water coolant in mezzanine space by inner layer steel plate and cooling gradually.There is the shortcoming that flow of cooling water distance is short, flow strength weak, heat interchanging area is little in this single stage cooling jacket structure for water, cooling performance is poor, and this had both affected quality product, also can affect the working reliability of blow-off valve.Xinzheng City Dongsheng Carbon Co., Ltd discloses a kind of " cooling device for discharging drum of calcining furnace " in the patent of declaring (201120091722.4), and the watercooling jacket of employing divides upper and lower two portions, and cooling performance is improved.But due to mobile distance and the flow strength deficiency of water coolant, heat interchanging area is little, cooling performance needs further to improve.
Summary of the invention
The object of the invention is to provide and a kind ofly can overcomes or avoid the shortcoming that exists in above-mentioned prior art or deficiency, speed of cooling is fast, effective heat exchange area is large, dump temperature is low, working reliability the is high finned refrigerating unit of can-type calcine furnace high temperature calcined coke plural serial stage.Its technical scheme is:
The finned refrigerating unit of a kind of can-type calcine furnace high temperature calcined coke plural serial stage, comprise the watercooling jacket of water inlet pipe, rising pipe and annular, it is characterized in that: watercooling jacket is multiple, multiple watercooling jackets superpose and are fixedly connected with, on the outer wall of each watercooling jacket inner side, be evenly provided with multiple fins, fin on multiple watercooling jackets is all corresponding in column, and each row fin is all positioned on same vertical surface; The two ends correspondence of each watercooling jacket is provided with water inlet pipe and rising pipe, and except being positioned at the rising pipe of watercooling jacket topmost and being positioned at the water inlet pipe of watercooling jacket bottom, rising pipe and water inlet pipe that adjacent watercooling jacket is positioned at same one end are communicated with through pipe connecting.
The described finned refrigerating unit of can-type calcine furnace high temperature calcined coke plural serial stage, is below hypotenuse on each fin, and angle between horizontal plane is 50 ° ~ 80 °, and watercooling jacket comprises 2～6.
Major advantage of the present invention and beneficial effect are:
1, multiple watercooling jacket stacks are composed in series, this has not only increased the mobile distance of water coolant greatly, and repeatedly pass in and out each watercooling jacket by water coolant, increase its flow strength, effectively raise the coefficient of heat transfer, strengthen cooling performance, be conducive to improve the quality of products and blow-off valve working reliability.
2, watercooling jacket is all evenly provided with multiple fins, this has not only increased the effective heat exchange area between watercooling jacket and high temperature calcined coke greatly, and fin is deep into the inside of high temperature calcined coke, heat transfer distances and the thermal resistance of internal high temperature calcined coke are effectively reduced, improve cooling speed and the homogeneity of high temperature calcined coke, be conducive to improve the quality of products and blow-off valve working reliability.
3, because the fin on multiple watercooling jackets is all corresponding in column, each row fin is all positioned on same vertical surface, make the arranged direction of all fins and the flow direction of high-temperature material consistent, and be hypotenuse below on fin, can ensure that material can not cause material channel to stop up because of forming scaffold.
