[0002] Carbon black is one of the oldest industrial products. As early as in ancient times, vegetable oil was used in China to produce pigment carbon black by incomplete combustion. The carbon black industry in China mainly uses the oil furnace method. There are few manufacturers using natural gas as raw material to produce carbon black. The main reasons are that the price of natural gas is relatively high, and its impurity content is relatively large. The quality of the produced carbon black is poor and can only be used as pigment carbon black, not as rubber carbon black.
[0003] At present, there is still a large amount of heat energy in the tail gas generated by the production of carbon black by the oil furnace method.

Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] Please refer to Figures 1-4 , the present utility model provides a tail gas heat energy recovery box for carbon black production. A tail gas heat energy recovery box for carbon black production includes a main box body 1. A plurality of carbon black tail gas heat conducting members 3 are slidably connected in sequence from top to bottom in the main box body 1, and a hose 4 is arranged between the air flow output ends of two adjacent carbon black tail gas heat conducting members 3. A lid 2 for transferring heat energy is installed on the top of the main box body 1;
[0029] Among them, the top carbon black tail gas heat conducting member 3 is connected to the intake end of the carbon black production tail gas.
[0030] In this embodiment, the lid 2 includes a main lid body 21. Two shunt boxes 24 are installed at the bottom of the main lid body 21. A plurality of guide holes 23 for shunting gas are installed on both shunt boxes 24. The tops of the two shunt boxes 24 are both communicated with a first guide pipe 22.
[0031] In this embodiment, the carbon black tail gas heat conducting member 3 includes a sealing plate 34. A positioning frame 33 is installed on the front surface of the sealing plate 34. A sealing plate 34 is installed on the side of the positioning frame 33 away from the main box body 1. A second diversion pipe 31 coiled in a snake shape is arranged inside the positioning frame 33. Both ends of the second diversion pipe 31 penetrate and extend outside the positioning frame 33. A plurality of heat conducting fins 32 are installed in parallel on the second diversion pipe 31.
[0032] In this embodiment, a sealing strip 38 is installed on the side of the positioning frame 33 close to the main box body 1. The positioning frame 33 is in close fit with the surface of the main box body 1 through the sealing strip 38.
[0033] In this embodiment, a plurality of card slots 35 are opened at the top of the positioning frame 33. Both sides of the plurality of heat conducting fins 32 are clamped with the positioning frame 33 through the card slots 35.
[0034] In this embodiment, both ends of the hose 4 are respectively connected to both ends of two adjacent second diversion pipes 31.
[0035] In this embodiment, a plurality of positioning blocks 5 that restrict the sliding of the carbon black tail gas heat conducting member 3 are installed on the inner wall of the main box body 1. The carbon black tail gas heat conducting member 3 further includes a connecting block 36. The connecting block 36 is connected to the positioning frame 33. A limiting groove 37 is opened on the connecting block 36. The positioning block 5 includes a positioning clamping block 51. The positioning clamping block 51 is connected to the inner wall of the main box body 1. Both sides of the positioning clamping block 51 are slidably connected with a pressing rod 54. One end of each of the two pressing rods 54 away from the carbon black tail gas heat conducting member 3 penetrates and extends out of the main box body 1. Both sides of the positioning clamping block 51 are rotatably connected with a rotating shaft 52. A rotating plate 53 is installed on each of the two rotating shafts 52. A guiding force plate 55 is installed on the north side of each of the two rotating plates 53. The positioning clamping block 51 and the adjacent connecting block 36 are mutually clamped;
[0036] Wherein, a torsion spring is arranged at the rotating connection part of the rotating shaft 52 and the positioning clamping block 51.
[0037] Further, if not so many carbon black tail gas heat conducting members 3 are needed, one group of the carbon black tail gas heat conducting members 3 can be drawn out and replaced with an empty frame with only the positioning frame 33, the sealing plate 34 and the connecting block 36 to enter.
[0038] Further, a torsion spring is arranged at the rotating connection part of the rotating shaft 52 and the positioning clamping block 51, and this torsion spring can make the initial position of the rotating plate 53 inserted into the limiting groove 37.
[0039] Further, the hose 4 is made of a high temperature resistant material.
[0040] The working principle and use process of the utility model: before using the device, a corresponding number of carbon black tail gas heat-conducting parts 3 are selected according to the estimated heat value. If the heat is low, the use of a group of carbon black tail gas heat-conducting parts 3 is reduced according to the above method. Then, the ports of two adjacent second guide pipes 31 on the remaining plurality of carbon black tail gas heat-conducting parts 3 are connected by a hose 4. Finally, two ports of the top second guide pipe 31 and the bottom second guide pipe 31 remain. One of the ports is connected to the external atmosphere, and the other port is connected to the exhaust valve of the carbon black production furnace body. When gas enters the second guide pipe 31, , heat is introduced into the main box 1 through the second guide pipe 31 and the plurality of heat-conducting fins 32, and at this time, one group of the first guide pipes 22 and the diverter box 24 enter the low-temperature gas through the guide hole 23, and then absorbs heat and flows out through another group of diverter boxes 24 and the first guide pipe 22, and continuously uses the low-temperature gas to absorb energy in exchange for heat energy, which is used for heating and heat preservation of other equipment. In this way, heat can be obtained without contacting the gas inside the second guide pipe 31, and pure heat energy can be obtained from the exhaust gas with more impurities, and excessive high temperature can be prevented from being directly discharged to harm the environment;
[0041] When the carbon black exhaust gas heat conducting member 3 is inserted into the main box body 1, the connecting block 36 will be inserted into the positioning block 51, and at this time, under the action of the torsion spring, the rotating plate 53 will rotate and be inserted into the limiting groove 37. At this time, the rotating plate 53 will restrict the connecting block 36 through the limiting groove 37, so that the connecting block 36 cannot be pulled out. When it is necessary to pull out the connecting block 36, it is only necessary to press the pressing rod 54, and the pressing rod 54 will resist the force guiding plate 55 to retract the rotating plate 53 into the positioning block 51. At this time, the rotating plate 53 will release the limit on the connecting block 36, and the carbon black exhaust gas heat conducting member 3 can be pulled open, thereby preventing the carbon black exhaust gas heat conducting member 3 from leaking and losing heat during the operation of the device;
[0042] A sealing strip 38 is provided to seal the gap between the sealing plate 34 and the main box body 1 .
[0043] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
