Description
Technical field
The present invention relates to a kind of can-type calcine furnace high temperature and forge the finned refrigerating unit of the burnt plural parallel stage in back, belong to solid high-temperature material cooling technology field.
Background technology
Refinery coke is the charcoal body thing that BO remaining after the 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 through high-temperature calcination, and charing forms calcined petroleum coke fully.Calcined petroleum coke is mainly used in Industrial products such as producing Graphite Electrodes, charcoal paste, silicon carbide, calcium carbide, and the market requirement is very big.At present, generally adopt can-type calcine furnace that refinery coke is calcined, calcining temperature is about 1300 ℃; Refinery coke after the calcining cools off through the single-stage watercooling jacket, then through the blow-off valve discharging.The single-stage watercooling jacket is generally the double-layer plate welded construction, and inner layer steel plate surrounds the passage of a high-temperature material; Form the annular gap water cavity of sealing between the inside and outside layer steel plate, be cooling-water duct.When the high temperature refinery coke when the single-stage watercooling jacket, heat is conducted to the water coolant in the mezzanine space and cooling gradually through inner layer steel plate.There is watercooling jacket top in this single-stage watercooling jacket structure and forges the shortcoming that the burnt heat transfer temperature difference in back is little, flow strength weak, heat interchanging area is little, and cooling performance is poor, and this had both influenced quality product, also can influence the working reliability of blow-off valve.The Xinzheng City Dongsheng Carbon Co., Ltd discloses a kind of " calcining furnace discharge barrel refrigerating unit " in the patent of declaring (201120091722.4), the watercooling jacket of employing divides two portions up and down, and cooling performance is improved.But because cooling-water flow intensity, heat transfer temperature difference and heat interchanging area are not enough, cooling performance awaits further to improve.
Summary of the invention
The object of the invention provides and a kind ofly can overcome or avoid the shortcoming that exists in the above-mentioned prior art or deficiency, speed of cooling is fast, effective heat exchange area is big, dump temperature is low, working reliability is high can-type calcine furnace high temperature to forge the finned refrigerating unit of the burnt plural parallel stage in back.Its technical scheme is:
A kind of can-type calcine furnace high temperature is forged the finned refrigerating unit of the burnt plural parallel stage in back; Comprise water inlet system and annular watercooling jacket; It is characterized in that: watercooling jacket is a plurality of, and a plurality of watercooling jacket stacks also are fixedly connected, and evenly are provided with a plurality of fins on the outer wall of each watercooling jacket inboard; Fin on a plurality of watercooling jackets is all corresponding to be become to be listed as, and each row fin all is positioned on the same vertical surface; Water inlet system comprises water inlet manifold and a plurality of water inlet arm that is connected with waterworks, is equipped with variable valve on each water inlet arm; One end of each watercooling jacket is provided with rising pipe, and the other end is communicated with a water inlet arm, the two ends of rising pipe and water inlet arm separation watercooling jacket.
Described can-type calcine furnace high temperature is forged back burnt plural parallel stage finned refrigerating unit, and the upper and lower limit of fin is hypotenuse, and the angle between the horizontal plane is 50 ° ~ 80 °, and watercooling jacket comprises 2～6.
Major advantage of the present invention and beneficial effect are:
1, comprise that a plurality of watercooling jacket stacks compose in parallel, making the high-temperature zone, top forge the burnt heat transfer temperature difference with water coolant in back increases, and the heat exchange effect strengthens; Can realize the control to each watercooling jacket flooding quantity through variable valve, increase its flow strength, thereby effectively improve the coefficient of heat transfer, enhanced cooling reduces dump temperature, helps improving the quality of products and the blow-off valve working reliability.
2, watercooling jacket all evenly is provided with a plurality of fins; This has not only increased watercooling jacket and high temperature greatly and has forged the effective heat exchange area between Jiao of back; And fin is deep into the inside that high temperature is forged back Jiao; Effectively reduced internal high temperature and forged back burnt heat transfer distances and thermal resistance, improved high temperature and forged burnt refrigerative speed in back and homogeneity, helped improving the quality of products and the blow-off valve working reliability.
3, because all corresponding one-tenth of the fin on a plurality of watercooling jackets is listed as, each row fin all is positioned on the same vertical surface; Make that the arranged direction of all fins is consistent with the flow direction of high-temperature material; And bottom is a hypotenuse on the fin, can guarantee that material can not cause material channel to stop up because of forming scaffold.
