Detailed Description
As shown in figures 1-4, the calciner for producing the carbon raw material petroleum coke for aluminum comprises a furnace body 1, wherein a plurality of groups of tank bodies 2 which are distributed in parallel along the length direction of the furnace body 1 are arranged in the furnace body 1, each group of tank bodies 2 is distributed along the width direction of the furnace body 1, a plurality of heating walls 3 are arranged in the furnace body 1, two adjacent groups of tank bodies 2 are isolated through the heating walls 3, the side walls at two ends of the furnace body 1 are respectively provided with one heating wall 3, the heating walls 3 are divided into ten layers of fire channels 5 which are communicated and are in an S-shaped trend along the height direction of the tank bodies 2 through a partition plate 4, the heating walls 3 are sequentially divided into a volatilization layer, a calcination layer and a cooling layer from top to bottom, the volatilization layer comprises a first layer of fire channel 5 and a second layer of fire channel 5, the cooling layer comprises a ninth layer of fire channel 5 and a tenth layer of fire channel 5, and the calcination layer comprises six layers of fire channels 5 positioned in the middle. The two layers of flame paths 5 are added to the calcining layers, so that the calcining time of the petroleum coke in the tank body 2 is increased, the petroleum coke is fully calcined, and the true density of the petroleum coke finished product is increased from 2.04 to 2.08 relative to the eight layers of flame paths 5.
Specifically, the upper portion of the tank body 2 is provided with a volatile outlet 6, the volatile outlet 6 is collected through a volatile collecting lane 7, all volatile collecting lanes 7 of each group of tank bodies 2 are collected through a volatile collecting lane 8, a volatile collecting lane 8 is arranged in the heating wall 3, and the first layer flame path 5, the third layer flame path 5 and the sixth layer flame path 5 are all provided with volatile inlets 9 and are communicated with the volatile collecting lane 8 through the volatile inlets 9. The volatile matters in the petroleum coke enter the flame path 5 through the volatile matters outlet 6, the volatile matters collecting and dividing path 7 and the volatile matters collecting and dividing path 8 to burn, so that the calcining layer reaches about 1200 ℃ to be calcined, and the flue gas enters the cooling layer along with the exhaustion of the volatile matters, the temperature of the cooling layer is gradually reduced due to the fact that no volatile matters continue to burn, and finally the flue gas is discharged from the flue 10.
Specifically, the tank body 2 includes conical bottom 11, and the discharge end of bottom 11 is equipped with tripper 12, and the outer spiral winding of bottom 11 has first water pipe 13, and first water pipe 13 is less than tenth layer flame path 5, and the upper end inner circumference of bottom 11 is equipped with cavity 14, and cavity 14 intussuseption is filled with insulating material or second water pipe 141, and wherein insulating material can be ceramic fiber. The first water pipe 13 is internally provided with cold water to forcibly cool the bottom 11 so that petroleum coke passing through the inside is rapidly cooled, and the first water pipe 13 is spirally wound on the side wall of the bottom 11 so that the periphery of the bottom 11 is cooled, and the petroleum coke in the first water pipe can be rapidly cooled. The arrangement of the heat insulating material or the second water pipe 141 reduces the influence of the lower end of the tank 2 on the cooling effect of the bottom 11, and the temperature of the lower end of the tank 2 is still higher, and the transmission of the temperature to the bottom 11 is reduced through the isolation, so that the cooling effect of the first water pipe 13 is accelerated to a certain extent.
Specifically, the upper end lateral wall of bottom 11 outwards protrudes the lower part of jar body 2, and the relative inner wall of bottom 11 is connected with high temperature resistant support frame 15, and the pointed end 16 of chevron shape is equipped with third water pipe 17 in the support frame 15 on the upper portion of support frame 15, and the water inlet end and the water outlet end of third water pipe 17 all pass the lateral wall of bottom 11 and communicate with the water inlet end and the water outlet end of first water pipe 13 respectively. The upper end side wall of the bottom 11 protrudes outwards from the lower portion of the can body 2, that is, into the bottom 11, the inner diameter of the can body 2 becomes large, and the supporting frame 15 may be made of a material having a high hardness, such as iron, stainless steel, or the like. The third water pipe 17 is arranged in the supporting frame 15, so that the temperature reduction of petroleum coke in the bottom 11 can be further accelerated. The herringbone tip 16, namely the upper part of the supporting frame 15, is provided with two connected inclined planes, which is beneficial to the petroleum coke to slide down from the upper part and avoid accumulation.
Specifically, the upper and lower parts of the side wall of the tip 16 are respectively provided with a spherical first tooth 161 and a conical second tooth 162, and the axes of the first tooth 161 and the second tooth 162 are perpendicular to the side wall of the tip 16. The provision of the first and second teeth 161, 162 facilitates crushing coked petroleum coke to avoid clogging the outlet of the bottom 11.
