Technical Field
The invention belongs to the technical field of production and application of forged coke, and particularly relates to a waste heat utilization system of a petroleum coke tank calciner.
Background
The petroleum coke is calcined at high temperature (about 1350 ℃) to remove volatile components, and is completely carbonized to form calcined petroleum coke (also known as calcined coke). The forged coke is widely applied to the production of aluminum electrolysis anodes, graphite electrodes for steelmaking, carburants, industrial silicon and other carbon products and is an important basic raw material.
At present, the forged coke is produced by a pot calciner. The tank type calcining process has two kinds of waste heat available for utilizing the waste heat of high temperature fume and the waste heat of high temperature calcined coke, and is especially tank type calcining furnace with petroleum coke fed into the tank via the top feeding device and heated gradually in the moving process from top to bottom. The heat generated by the combustion of fuel in the flame path is indirectly transferred to the petroleum coke through the flame path wall. When the temperature of the petroleum coke reaches 350-600 ℃, a large amount of volatile components are released. Is collected through volatile component channels and sent into a flame path for combustion. Combustion of the volatile components is yet another source of heat for the pot calciner. Petroleum coke is cooled by a water jacket from the bottom of a charging bucket after a series of physical and chemical changes are completed at the high temperature of about 1350 ℃, and finally is discharged out of the furnace by a discharging device. The waste flue gas after heat exchange is sent to a waste heat boiler to produce steam by using the waste heat of the waste flue gas, or sent to a heat exchange chamber to preheat air for fuel and volatile component combustion.

Detailed Description
In order that the above objects, features and advantages of the invention will be more clearly understood, a further description of the invention will be rendered by reference to the appended drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as described herein, and therefore the present invention is not limited to the specific embodiments of the disclosure that follow.
In order to achieve the above objective, the waste heat utilization system of the petroleum coke tank calciner 1 provided in the embodiment includes the steam generator 2, the super-cooling water jacket 3 and the discharging device 4 sequentially disposed below the petroleum coke tank calciner 1, wherein the steam generator 2 and the super-cooling water jacket 3 each include vertically disposed heat exchange tubes 21, the heat exchange tubes 21 are disposed at intervals, the membrane 22 is disposed between adjacent heat exchange tubes 21, and the heat exchange tubes 21 are disposed in a square shape by the arrangement of the membrane 22.
The discharging device 4 comprises a device body and a rotating shaft 41 which is rotatably arranged in the device body, wherein the device body is provided with a top and an opening obliquely arranged below, the rotating shaft 41 is arranged in the device body, a material separating plate 42 is arranged on the rotating shaft 41 at intervals, the material separating plate 42 is axially arranged along the rotating shaft 41, a hopper is formed between two adjacent material separating plates 42, 5 hoppers are arranged in total, and 6 hoppers are arranged in this embodiment, so that the rotating shaft 41 rotates by a certain angle every 2 hours, cooled forged coke is discharged, and a new forged coke Jiao Jiuhui moves downwards. The above structure is a conventional common structure, and in this embodiment, it is not described in detail.
Considering that the movement of the forged coke mainly depends on gravity to move downwards, only the mechanism needing external driving only needs to have the rotating shaft 41, the main reason that the heat exchange fins 23 are not arranged is that carbon films are accumulated when the included angle formed between the heat exchange fins 23 is used for a long time, friction generated by the downward movement of the forged coke can not be rubbed off due to the existence of the included angle, the calcined coke basically moves downwards for a distance of two hours, the friction force is not large, so that the more and more heat exchange effects are caused under the accumulation of daily months, the key for solving the problems is that the two heat exchange fins 23 are kept to move at the gap so as to be difficult to accumulate, and in order to achieve the purpose, the heat exchange fins 23 are arranged on the tube wall of the heat exchange tube 21 which is axially parallel to the rotating shaft 41 (in the long-side direction of the steam generator 2), and the purpose of only arranging one side is mainly that the short-side direction cannot be effectively utilized to rotate the rotating shaft 41. The length of the long side of the steam generator 2 is far longer than that of the short side, and the steam generator is only arranged on the side edges of the two long sides, so that a better heat exchange effect can be achieved.
Of course, the heat exchange fins 23 are arranged on the side wall of the heat exchange tube 21 facing the inside of the steam generator 2 at intervals, the cleaning rods 5 are arranged on the side walls of the two adjacent heat exchange fins 23, the cleaning rods 5 are required to be in contact with the tube walls of the heat exchange tube 21 and the side walls of the heat exchange fins 23, the guide rods 7 are arranged at the bottoms of the cleaning rods 5, one guide rod 7 is arranged below the cleaning rods 5 of the one side steam generator 2, and therefore, the guide rods 7 and the cleaning rods 5 are vertically arranged, the cleaning rods 5 are arranged on the guide rods 7 at intervals, and because the heat exchange fins 23 are distributed in an arc shape, the cleaning rods 5 on the one heat exchange tube 21 are also distributed in an arc shape, and for the purpose, the arc-shaped connecting plates 6 are arranged below the cleaning rods 5 are arranged on the guide rods 7 through arc-shaped connecting rods, and in the embodiment, the guide rods 7 are arranged in a vertically arranged plate shape.
In order to utilize the rotation state of the rotating shaft 41, in the present embodiment, the guide rod 7 is disposed in the discharging device 4, and the guide plates 43 are further disposed between the partition plates 42, in the present embodiment, three guide plates 43 are disposed in total along the axial direction of the rotating shaft 41, and due to the rotation of the rotating shaft 41, the partition plates 42 are rotated, and if the guide rod 7 contacts with the partition plates 42 while the rotating shaft 41 is stationary, and when the rotating shaft 41 moves, the guide plates 43 move downward due to lack of support of the partition plates 42, and since the cleaning rod 5 is disposed between the two heat exchanging fins 23, the up-down movement thereof causes no connection between the carbon films, and thus no accumulation can be formed.
In order to switch the guide plates 43 between different partition plates 42, in the present embodiment, the guide plates 43 are disposed downward in an arc shape from the partition plates 42 to a position intermediate the two partition plates 42, and the bottom of the guide rod 7 is disposed in contact with the top surface of the guide plates 43. In this way, under the support of the guide plate 43, the switching between different material separating plates 42 is realized, meanwhile, due to the action of the guide plate 43, the guide rod 7 is changed into a lower-upper movement in the time of switching a hopper, so that better cleaning is formed for the carbon film, meanwhile, due to the upward movement process, the calcined coke just moves downwards, and the reverse movement is formed between the calcined coke and the calcined coke, so that the friction force is increased, the surface of the cleaning rod 5 is ensured not to accumulate the carbon film, the upward movement of the cleaning rod 5 is facilitated, the top of the cleaning rod 5 is provided with an inclined plane, and the problem that in the embodiment, the size of the discharging device 4 in fig. 2 and 3 is enlarged for facilitating the observation, so that the proportion is inconsistent is required.
Because the cleaning rod 5 moves up and down, the limiting mechanism is required to enable the cleaning rod to stably move up, and the limiting mechanism is arranged to cover a carbon film possibly, so that the cleaning rod 5 is required to be improved on the basis of the existing structure to achieve limiting, and the cleaning rod 5 is mainly provided with the heat exchange fins 23, and the heat exchange fins 23 comprise connecting portions 231 connected with the heat exchange tubes 21 and heat exchange portions 232 arranged at one ends of the connecting portions 231 far away from the heat exchange tubes 21, wherein the cross sections of the connecting portions 231 are arranged in a trapezoid shape, and the width of one surface of the connecting portions 231 far away from the heat exchange tubes 21 is larger than that of one surface of the connecting portions 231 close to the heat exchange tubes 21. Because the heat exchange fins 23 are distributed in an arc shape, the heat exchange fins are arranged on the heat exchange tube 21 in a divergent mode, the heat exchange fins are divided into two parts, the distance between the connecting parts 231 of two adjacent heat exchange fins 23 and the bottom of the heat exchange part 232 is reduced, the distance between the side surfaces of the connecting parts 231, which are close to the heat exchange tube 21, is increased, and therefore the part of the cleaning rod 5 is arranged according to the shape formed by the connecting parts 231 and the tube wall of the heat exchange tube 21, limiting of the cleaning rod 5 can be effectively achieved, meanwhile, the cleaning rod 5 is filled to prevent the burnt entering after forging, and cleaning is more convenient.
In this embodiment, the cross section of the heat exchanging portion 232 is rectangular, and the width of the surface of the heat exchanging portion 232 near the connection portion 231 is smaller than the width of the surface of the connection portion 231 near the heat exchanging tube 21. Therefore, due to the divergent arrangement of the heat exchange fins 23, the heat exchange parts 232 of the two heat exchange fins 23 are spaced farther apart, which is more beneficial to heat exchange, and meanwhile, the accumulation of carbon films is avoided.
To match the arrangement of the heat exchange fins 23, in the present embodiment, the cleaning lever 5 includes guide portions 51 provided between the connection portions 231 and cleaning portions 52 provided between the heat exchange portions 232. The shape of the guiding portion 51 is defined by the connecting portion 231 and the wall of the heat exchange tube 21, and the cleaning portion 52 is mainly configured to complete an arc-shaped included angle formed by the connection between the connecting portion 231 and the heat exchange portion 232, so that a line from a midpoint of the heat exchange tube 21 to a center point of an end surface of the cleaning portion 52, which is far from the guiding portion 51, is smaller than a line from a midpoint of the heat exchange tube 21 to a center point of an end surface of the heat exchange portion 232, which is far from the connecting portion 231. Therefore, the contact surface maximization design can be ensured, and the heat exchange effect is improved.
In order to facilitate the movement of the guide bar 7 on the top surface of the guide plate 43, in this embodiment, the bottom surface of the guide bar 7 is arranged in an arc shape.
Through the arrangement, the accumulation of the carbon film is effectively avoided under the condition of adding the heat exchange fins 23, so that the cleaning problem of the steam generator 2 is avoided.
The present invention is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present invention without departing from the technical content of the present invention still belong to the protection scope of the technical solution of the present invention.
