[0002] Carbon disulfide is an inorganic substance, chemical formula is CS2, common solvent, colorless liquid, pure carbon disulfide used in the laboratory has a sweet aroma similar to chloroform, but the industrial product is usually impure and yellowish because of the presence of other sulfides, and has an unpleasant taste of rotten beets, it can dissolve sulfur, carbon disulfide is used to make rayon, pesticides, accelerators, etc., and also used as a solvent, according to the characteristics of carbon disulfide, it is suitable for continuous semi-coke method carbon disulfide reaction furnace, carbon disulfide reaction furnace produces harmful gas to human body when reacting, which cannot be directly discharged and needs to be treated to meet the standard before being discharged.

[0003] Chinese invention patent CN2016107200296 discloses a carbon disulfide reaction furnace, which comprises a furnace body, a feeding port, a discharging port and a slag outlet, the furnace body is divided into at least upper and lower two sections, the lower section is provided with a movable inner container, the inner container separates the space in the furnace body into a reaction chamber and a sulfur gasification chamber, the lower part of the inner container is provided with an inclined air hole, the air hole is higher at one end of the sulfur gasification chamber than at one end of the reaction chamber, and at least one sulfur adding port is arranged on the furnace body constituting the sulfur gasification chamber, but the carbon disulfide reaction furnace usually filters and discharges through an external treatment device, which occupies a very large space and increases the use cost, and the heat contained in the discharged waste gas cannot be effectively applied to help waste gas treatment, resulting in waste of energy, so a continuous semi-coke method carbon disulfide reaction furnace without harmful gas emission is needed.

[0004] Chinese invention patent CN021476780 discloses a process for producing carbon disulfide by semi-coke-sulfur method, semi-coke is added into the reaction furnace according to different particle size ratio, and chemical reaction is carried out with gaseous sulfur in the furnace at a temperature of 850-1000 DEG C to generate carbon disulfide gas, the carbon disulfide gas is discharged from the gas outlet at the top of the reaction furnace and enters the condensing system; during production, semi-flow bed feeding method is adopted, the cleaning interval of the slag generated after reaction is 48-72 hours, and the semi-coke is added in time after cleaning of the slag to ensure continuous reaction, therefore, the particle size of the semi-coke added into the reaction furnace should be controlled within 10-30 mm, the particle size ratio is 25-35% of 10 mm, 25-35% of 20 mm and 35-45% of 30 mm, but the existing device cannot accurately control and adjust the amount of semi-coke with different particle sizes during actual production, thereby causing low quality of the output and failing to meet normal production requirements.

[0005] At the same time, the activated carbon is prone to internal blockage during long-term use, thereby reducing the filtering and cleaning effect on carbon disulfide, and because the activated carbon is deactivated, the discharge path of the output carbon disulfide is blocked, further reducing the yield and concentration thereof. When discharging, the discharge pipe is blocked due to poor discharge of waste and sundries in the reaction furnace, which affects subsequent production. In addition, uneven stirring of the semicoke inside during the reaction affects the subsequent reaction and reduces the quality of the reaction product. SUMMARY

Embodiment

[0031] Based on the first embodiment, a continuous semi-coke carbon disulfide reaction furnace without harmful gas emission is provided. In actual use, raw material semi-coke needs to be added to the reaction kettle 5. The main component of semi-coke is the product of low-temperature dry distillation of lignite, which is a carbon material with high carbon content, easy to burn, and has high chemical activity, which is beneficial to the chemical diffusion of sulfur vapor. However, due to the large pore size of semi-coke, the adsorption of sulfur is poorer than that of charcoal, and it is not easy to form ash after reaction, which affects the carbon supplement space. In order to solve this problem, when semi-coke is selected, it is necessary to use semi-coke with different particle sizes, so the particle size ratio of semi-coke used is 10mm for 25-35%, 20mm for 25-35%, and 30mm for 35-45%. By using this ratio, the amount of semi-coke added can be increased, the gas resistance can be increased, and the time of sulfur staying in the reaction furnace can be prolonged, which can promote the smooth progress of the chemical reaction. Therefore, when adding semi-coke, the addition ratio needs to be adjusted according to different particle sizes to obtain the best reaction effect.

[0032] Meanwhile, after the device is used for a long time, the activated carbon plate 18 will gradually be deactivated due to clogging. The deactivated activated carbon plate 18 not only loses the adsorption capacity for impurities of the product carbon disulfide, but also affects the subsequent normal discharge of carbon disulfide, hinders the subsequent reaction, and thus reduces the yield. In order to solve the above problems, the self-adaptive adjusting device adjusts the matching ratio of different particle sizes of semi-coke, and also revives the deactivated activated carbon plate 18 and improves the cleaning capacity of the device for the inside of the reaction kettle 5. The internal heat type continuous semi-coke carbon disulfide reaction furnace without harmful gas emission also comprises: a threaded transmission rod, one end of the threaded transmission rod away from the slag discharge pipe 6 is provided with a fan blade, so that the rotation of the driving motor 23 not only drives the threaded transmission rod to rotate and convey the waste discharged from the slag discharge pipe 6 into the cooling water tank 24 for recycling, but also drives the fan blade to rotate when the driving motor 23 rotates, thereby pumping air inside the whole discharge bin 22 and the reaction kettle 5, and cooperating with the rotation of the threaded transmission rod to clean the inside of the reaction kettle 5 thoroughly and effectively. The discharge bin 22 away from the fan blade is provided with an air outlet, which is mainly used for discharging the gas inside when pumping air. The other end of the air outlet is communicated with a recovery gas bag, which is convenient for recycling waste gas and avoiding environmental pollution.

[0033] One side of the air outlet pipe 9 is communicated with a heat pipe 27 through a first electromagnetic valve. The other end of the heat pipe 27 bypasses the treatment bin 13 and is communicated with the other side of the air outlet pipe 9. When the first electromagnetic valve is opened, the heat pipe 27 can guide the high-temperature carbon disulfide gas discharged along the air outlet pipe 9. The heat pipe 27 is in contact with the treatment bin 13, so that the high-temperature carbon disulfide gas entering the heat pipe 27 will conduct heat with the treatment bin 13. Therefore, the heat can be transmitted to the activated carbon plate 18 through heat conduction, and the deactivated activated carbon plate 18 can be revived again in a high-temperature environment. When the first electromagnetic valve is closed, the heat pipe 27 is no longer supplied with high-temperature carbon disulfide gas, and the activated carbon plate 18 returns to normal and continues to work.

[0034] The input end of the heat pipe 27 is located at the front end of the air outlet pipe 9, and the output end of the heat pipe 27 is located at the tail end of the air outlet pipe 9. In this way, when the first electromagnetic valve is opened, the high-temperature carbon disulfide gas discharged from the air outlet pipe 9 can enter the front end of the heat pipe 27, flow through the heat pipe 27 to the rear end, and then re-enter the air outlet pipe 9, thereby reviving the activated carbon plate 18 by virtue of the high-temperature characteristics of the high-temperature carbon disulfide gas, while not causing excessive waste of the product carbon disulfide gas.

[0035] One side of the top cover 8 is provided with a first discharge bin 25 through a second electromagnetic valve, one side of the heat pipe 27 is provided with a first bellows pipe 28 through a first flow valve, the other end of the first bellows pipe 28 is provided with a first baffle 29, the first baffle 29 is slidably connected with the first discharge bin 25, the gas content entering the first bellows pipe 28 along the heat pipe 27 can be controlled through the first flow valve, thereby controlling the deformation amount of the first bellows pipe 28, further controlling the moving distance of the first baffle 29 in the first discharge bin 25, and the volume of the first discharge bin 25 will also change accordingly. The same particle size of semi-coke is placed in the first discharge bin 25, when the first discharge bin 25 is filled, the second electromagnetic valve is opened to pour it into the reaction kettle 5 for subsequent reaction.

[0036] The other end of the top cover 8 is provided with a second discharge bin 26 through a third electromagnetic valve, the other side of the heat pipe 27 is provided with a second bellows pipe 30 through a second flow valve, the other end of the second bellows pipe 30 is provided with a second baffle 31, the second baffle 31 is slidably connected with the second discharge bin 26, and the same as the first discharge bin 25, the amount of gas entering the second bellows pipe 30 can be effectively controlled by controlling the opening degree of the second flow valve, thereby controlling the deformation amount of the second bellows pipe 30, further controlling the moving distance of the second baffle 31 in the second discharge bin 26, and the volume of the second discharge bin 26 will also change. Among them, the volumes of the first discharge bin 25 and the second discharge bin 26 are mainly compared, thereby controlling the content ratio of the semi-coke of the same particle size in the first discharge bin 25 and the semi-coke of different particle sizes in the second discharge bin 26, and further improving the effect of sulfur dioxide reaction.

[0037] Among them, displacement sensors are arranged in the first discharge bin 25 and the second discharge bin 26, the heights of the first discharge bin 25 and the second discharge bin 26 are the same, the greater the transverse displacement ratio of the first baffle 29 and the second baffle 31 in the first discharge bin 25 and the second discharge bin 26, the smaller the volume of the first discharge bin 25 and the second discharge bin 26, so the displacement amount of the first baffle 29 and the second baffle 31 can be detected through the displacement sensor, and the height values of the first discharge bin 25 and the second discharge bin 26 are the same, thereby quickly and efficiently calculating the content of the semi-coke in the first discharge bin 25 and the second discharge bin 26, and controlling the appropriate proportion of adding, thereby improving the subsequent reaction effect.

[0038] In use, first, the impurities in the reaction kettle 5 need to be cleaned, at this time the driving motor 23 is started, the driving motor 23 drives the fan blade to rotate, the fan blade rotates to exhaust the inside of the discharge bin 22 and the reaction kettle 5, so that the impurities and gas in the reaction kettle 5 enter the inside of the discharge bin 22 along the slag outlet pipe 6, at the same time, the rotation of the driving motor 23 drives the threaded transmission rod to rotate, the rotation of the threaded transmission rod transmits and feeds the impurities in the discharge bin 22 to make them quickly fall into the cooling water tank 24.

[0039] When the fan blade rotates to pump the reaction kettle 5, the outside air will enter the treatment bin 13 along the exhaust pipe 14, and the outside air can impact the reaction in the activated carbon plate 18, so that the impurities clamped in the activated carbon plate 18 are removed, thereby ensuring to improve the durability of the activated carbon plate 18.

[0040] At the same time, the outside air enters the exhaust pipe 9 along the treatment bin 13, the first electromagnetic valve is opened, and the gas enters the heat conducting pipe 27 inside along the exhaust pipe 9. At this time, the gas circulates along the heat conducting pipe 27 and then reaches the exhaust pipe 9 and enters the reaction kettle 5. In order to control the amount of semi-coke added to the reaction kettle 5, the amount of semi-coke with different particle sizes is different, so that the first flow valve in the first bellows pipe 28 is opened, and the second flow valve in the second bellows pipe 30 is opened. At the same time, the opening degree of the first flow valve and the second flow valve is controlled to be different, and due to the pumping effect of the fan blade, the moving distance of the first bellows pipe 28 and the second bellows pipe 30 is different, so that the moving distance of the first baffle 29 in the first discharge bin 25 is different from the moving distance of the second baffle 31 in the second discharge bin 26, and both of them cause the volume of the first discharge bin 25 and the second discharge bin 26 to decrease, and the displacement sensor detects different displacement values. The distance value detected in the first discharge bin 25 is the distance value between the first baffle 29 and the inner wall of the first discharge bin 25, and the distance value detected in the second discharge bin 26 is the distance value between the second baffle 31 and the inner wall of the second discharge bin 26. Since the height of the first discharge bin 25 and the second discharge bin 26 is the same, the volume ratio of the first discharge bin 25 and the second discharge bin 26 is related to the displacement amount of the first baffle 29 and the second baffle 31. The greater the moving distance of the first baffle 29, the smaller the distance between the first baffle 29 and the inner wall of the first discharge bin 25, and the smaller the volume of the first discharge bin 25, and the smaller the proportion of the particle size content of the semi-coke in the first discharge bin 25.

[0041] Therefore, by controlling the size of the first flow valve and the second flow valve, the volume of the first discharge bin 25 and the second discharge bin 26 can be effectively controlled, and the content of the semi-coke with different particle sizes can be further controlled to meet the required proportion requirement, thereby improving the effect of subsequent reaction.

[0042] When the semi-coke raw materials with different particle sizes are added to the corresponding first discharge bin 25 and second discharge bin 26 and filled, the driving motor 23 stops working, the second electromagnetic valve and the third electromagnetic valve are opened, and the semi-coke raw materials in the first discharge bin 25 and the second discharge bin 26 are directly discharged into the reaction kettle 5 for subsequent reaction.

[0043] Therefore, when more groups of particle size semi-coke need to be put in, the number of the feeding bins can be increased according to the above method, and the corresponding number of the feeding bins can be increased by connecting the bellows and the baffle through the flow valve inside the corresponding feeding bin, thereby realizing the one-time proportional feeding of more different particle size semi-coke raw materials, and further improving the adaptability of the device.

[0044] After the feeding is completed, liquid sulfur is added into the reaction kettle 5 along the sulfur adding pipe 7 to react with the semi-coke in the reaction kettle 5. During the reaction process, the generated sulfur gas enters the gas outlet pipe 9 from the reaction kettle 5. At this time, the first electromagnetic valve is closed, and the sulfur gas in the gas outlet pipe 9 reaches the inside of the liquid storage box 10. The liquid in the liquid storage box 10 is heated by the heat conduction of the high-temperature gas outlet pipe 9, and the high-temperature liquid in the liquid storage box 10 enters the treatment bin 13 along the hose 12 at this time. The gas in the gas outlet pipe 9 enters the treatment bin 13, and the entering liquid cools, removes and neutralizes the sulfur gas. At the same time, the treated sulfur gas rises to the activated carbon plate 18 along the treatment bin 13, and is further removed and treated by the adsorption of the activated carbon plate 18, and is then discharged through the gas hole 20 at the top and collected by the sulfur gas recovery box.

[0045] The activated carbon plate 18 is easily clogged and deactivated after long-term use, and hinders the discharge of the subsequent product. When the amount of sulfur gas discharged through the gas hole 20 decreases, the first electromagnetic valve is opened, the high-temperature sulfur gas in the gas outlet pipe 9 enters the heat conduction pipe 27, and the first flow valve and the second flow valve are both closed. The high-temperature sulfur gas in the heat conduction pipe 27 reaches the treatment bin 13, and the heat conduction effect of the high-temperature gas can transfer the heat of the heat conduction pipe 27 to the activated carbon plate 18 in the treatment bin 13, so that the activated carbon plate 18 is revived in the high-temperature environment and regains the filtering performance. The high-temperature sulfur gas in the heat conduction pipe 27 continues to move to the rear end along the heat conduction pipe 27 and returns to the gas outlet pipe 9 to continue the subsequent removal effect. Through the flow direction control of the high-temperature sulfur gas in the gas outlet pipe 9, the deactivated activated carbon plate 18 can be effectively revived, further improving the durability of the device, and without affecting the subsequent reaction and collection.

[0046] When the reaction is completed, the sulfur gas collection box is removed, and only the switch of the slag outlet pipe 6 is opened. The driving motor 23 is started to drive the threaded transmission rod and the fan blade to rotate. The impurities and gas in the reaction kettle 5 are sucked into the discharge bin 22 by the fan blade, and are cooled and recovered in the cooling tank 24 by the threaded transmission rod. The impurity gas reaches the recovery gas bag through the gas hole for recovery treatment.

[0047] When the impurities in the reaction kettle 5 are recovered, and subsequent reaction is needed, only the above operation needs to be repeated, the opening size of the first flow valve and the second flow valve is controlled, and then the volume of the first discharging bin 25 and the second discharging bin 26 is adjusted, so that the subsequent feeding and reaction process is completed.

[0048] The device can effectively control the addition amount of semi-coke with different particle sizes, thereby meeting the actual demand, improving the adaptability, and recycling the impurities in the reaction kettle 5 when adjusting the addition amount of semi-coke, improving the multi-functionality of the device, saving time, improving the reaction efficiency, and in the case that the activated carbon plate 18 is deactivated due to long-time work, the deactivated activated carbon plate 18 is high-temperature revived by the high-temperature sulfur gas as the reaction product, so that the activated carbon plate 18 regains the required filtering effect, improving the durability of the device, reducing the reaction consumption, and ensuring the reaction effect.
