Description

Technical Field

[0001] This utility model relates to a reaction vessel, specifically a chlorination reaction vessel with variable airflow. Background Technology

[0002] A chlorination reactor is a specialized piece of chemical equipment used for chlorination reactions. Chlorination refers to the process of introducing chlorine gas into raw materials, where chlorine products are generated through the formation or substitution of chemical bonds. This type of reaction is widely used in chemical engineering, pharmaceuticals, materials science, and environmental protection.

[0003] The workflow of a chlorination reactor typically includes raw material preparation, gas introduction, reaction control, product separation, and tail gas treatment. With safety, efficiency, and controllability as its core principles, it achieves high-quality synthesis of the target product by precisely controlling parameters such as Cl2 flow rate, temperature, and mixing efficiency, while minimizing safety risks and environmental pollution. Controlling the chlorine gas introduction rate effectively maintains stable pressure within the reactor, preventing overpressure (leading to leakage or explosion risks) or negative pressure (potentially causing air intake hazards); valves are commonly used for this control.

[0004] Normally, the reactor is sealed, and operators can judge the reaction status by the pressure changes inside the reactor. When the pressure inside the reactor is too high (the reaction rate is too fast and too violent), the chlorine gas introduction rate is usually reduced by valves to moderate and stabilize the chlorination reaction. However, since there is no necessary correlation between the valve control of the chlorine gas introduction rate and the pressure inside the reactor, when the reaction is too violent, turning the valve often results in either the valve being too tight (chlorine gas introduction rate is too slow) or too loose (chlorine gas introduction rate is still too fast), which can lead to low reaction efficiency or failure to moderate the reaction.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0045] Please see Figures 1-7 As an embodiment of the present invention, the variable airflow chlorination reactor includes a reactor body 1; a reactor cover 2 is sealed to the reactor body 1 by bolts.

[0046] An air inlet pipe 3 and a pressure relief pipe 7 are fixedly installed on the vessel lid 2; multiple sets of sealing plates 6 are rotatably installed on the air inlet pipe 3;

[0047] A fixing plate 8 is fixedly installed on the pressure relief pipe 7; multiple sets of first pressure relief holes 801 are opened on the fixing plate 8;

[0048] The vessel body 1 is provided with a sensing structure for sensing pressure changes inside the vessel body 1;

[0049] The vessel body 1 is equipped with a flow conversion structure and a pressure relief structure;

[0050] When the pressure inside the vessel 1 increases, the sensing structure will drive the flow conversion structure and the pressure relief structure to operate.

[0051] The converter structure will drive multiple sets of sealing plates 6 to rotate synchronously and move closer to each other, thereby reducing the conduction area of ​​the air inlet pipe 3; and when the sealing plates 6 are in contact with each other to block the air inlet pipe 3, the pressure relief structure will open the first pressure relief hole 801 to reduce the pressure inside the vessel body 1.

[0052] In this embodiment, the vessel body 1 and the vessel cover 2 are connected by bolts to ensure that there is no gas or liquid leakage during the chlorination reaction, thereby ensuring the safety of the chlorination reaction process.

[0053] The inlet pipe 3 is connected to the chlorine tank, and chlorine can flow into the vessel 1 through the inlet pipe 3 to replenish the chlorine consumed in the chlorination reaction in real time.

[0054] The sealing plates 6 can rotate synchronously to move closer or further apart; thereby reducing or increasing the conduction area of ​​the air inlet pipe 3, thus reducing or increasing the chlorine content in the vessel body 1.

[0055] The pressure change inside vessel 1 is related to the efficiency of the chlorination reaction; when the chlorination reaction is faster, the pressure increase rate inside vessel 1 is relatively larger; conversely, the pressure increase rate is smaller.

[0056] When the chlorination reaction in vessel 1 is relatively vigorous, the pressure inside vessel 1 will increase. At this time, the sensing structure will sense the pressure change inside vessel 1 in real time and drive the flow conversion structure and pressure relief structure to operate.

[0057] By driving the converter structure to rotate and move closer to each other, the conduction area of ​​the inlet pipe 3 is reduced, thereby reducing the replenishment rate of chlorine gas and thus slowing down the reaction rate. This moderates and stabilizes the chlorination reaction, thereby avoiding an overly violent reaction process that could lead to pressure imbalance in the reactor and increase the probability of explosions or other dangers.

[0058] When the flow converter structure moves and causes the sealing plate 6 to block the air inlet pipe 3, the reaction process inside the vessel 1 still cannot be slowed down and stabilized. At this time, the induction structure will continue to move and drive the pressure relief structure to move, thereby opening the first pressure relief hole 801, so that the air inside the vessel 1 and the outside air can flow to each other, thereby reducing the pressure inside the vessel 1 and ensuring the safe operation of the reactor.

[0059] The induction structure senses the pressure changes inside the reactor in real time and alternately drives the flow conversion structure and the pressure relief structure according to the pressure change. This reduces the replenishment rate of chlorine gas by reducing the conduction area of ​​the inlet pipe 3, thereby slowing down and stabilizing the reaction process. When the pressure inside the reactor is too high, the first pressure relief hole 801 is opened to reduce the pressure inside the reactor, thereby ensuring the safe operation of the reactor.

[0060] As a further embodiment of this utility model, the sensing structure includes a sensing tube 10 fixedly installed on the lid 2; a piston 11 is slidably and sealed inside the sensing tube 10; a sliding rod 12 is fixedly installed on the piston 11 and slidably fitted with the sensing tube 10; a spring 13 is sleeved on the sliding rod 12; the two ends of the spring 13 respectively abut against the piston 11 and the sensing tube 10.

[0061] In this embodiment, when the pressure inside the vessel 1 increases, it will squeeze the piston 11, thereby causing the piston 11 to slide away from the vessel 1 inside the sensing tube 10, which in turn causes the slide rod 12 to slide into contact with the sensing tube 10.

[0062] Furthermore, during the sliding process of piston 11, spring 13 will be compressed, and as the compression of spring 13 increases, the elastic force of spring 13 will also gradually increase.

[0063] When the pressure inside the vessel 1 decreases, the elastic force of the spring 13 can drive the piston 11 to slide towards the vessel 1, thereby completing the reset.

[0064] Spring 13 can increase the resistance of piston 11 sliding away from vessel 1, and the resistance will increase as the sliding distance of piston 11 increases; the force of gas pressure in vessel 1 pushing piston 11 and the elastic force of spring 13 work together to increase the pressure value of the sensing structure (the value at which the pressure in vessel 1 can push piston 11 to slide), so as to ensure that the chlorination reaction can proceed normally.

[0065] The induction structure senses the pressure changes inside the reactor in real time and alternately drives the flow conversion structure and the pressure relief structure according to the pressure change. This reduces the replenishment rate of chlorine gas by reducing the conduction area of ​​the inlet pipe 3, thereby slowing down and stabilizing the reaction process. When the pressure inside the reactor is too high, the first pressure relief hole 801 is opened to reduce the pressure inside the reactor, thereby ensuring the safe operation of the reactor.

[0066] As a further embodiment of this utility model, the converter structure includes a first gear 5 rotatably mounted on the intake pipe 3; and the first gear 5 is sealed to the intake pipe 3; the first gear 5 has multiple sets of inclined grooves 501; and the sealing plate 6 is fixedly mounted with a protruding post 601 that slides and engages with the inclined grooves 501.

[0067] In this embodiment, after the pressure inside the vessel 1 increases to a certain value, the sensing structure will drive the first gear 5 to rotate in the forward direction, thereby driving multiple sets of inclined grooves 501 to rotate synchronously, thereby driving the inclined grooves 501 to slide and engage with the protruding column 601.

[0068] The protruding column 601 is squeezed by the wall of the inclined groove 501, which can drive the sealing plate 6 to rotate and move closer to each other, thereby reducing the conduction area of ​​the air inlet pipe 3, reducing the replenishment rate of chlorine gas, and thus slowing down and stabilizing the chlorination reaction in the vessel 1.

[0069] When the pressure inside the vessel 1 decreases, the sensing structure will drive the first gear 5 to rotate in the opposite direction, thereby restoring the conduction area of ​​the air inlet pipe 3 to ensure the reaction efficiency of the chlorination reaction.

[0070] As a further embodiment of this utility model, the pressure relief structure includes a second gear 9 rotatably mounted on the pressure relief pipe 7; and the second gear 9 and the fixing plate 8 are in a sealing fit against each other; the second gear 9 is provided with a second pressure relief hole 901 that can cooperate with the first pressure relief hole 801.

[0071] In this embodiment, when the induction structure drives the flow conversion structure to block the air inlet pipe 3, and the chlorination reaction in the reactor is still relatively intense and the pressure in the reactor continues to rise, the induction structure will drive the pressure relief structure to operate.

[0072] In the initial state, the first pressure relief hole 801 and the second pressure relief hole 901 are misaligned, thereby blocking the first pressure relief hole 801, thus maintaining the pressure balance inside the reactor and ensuring the orderly progress of the chlorination reaction.

[0073] When the induction structure drives the pressure relief structure to operate, the second gear 9 will rotate, thereby driving the second pressure relief hole 901 to rotate, so that the first pressure relief hole 801 and the second pressure relief hole 901 are aligned with each other, so as to open the first pressure relief hole 801; allowing the air in the reactor to flow out through the first pressure relief hole 801, thereby reducing the pressure in the reactor and avoiding the occurrence of dangerous accidents.

[0074] As a further embodiment of this utility model, a first incomplete gear 14 and a second incomplete gear 15 are rotatably connected to the sensing tube 10; wherein the first incomplete gear 14 meshes with the first gear 5; the second incomplete gear 15 meshes with the second gear 9; a first drive groove group and a second drive groove group are provided on the slide rod 12; a first protruding post 1401 that slides and engages with the first drive groove group is fixedly installed on the first incomplete gear 14; a second protruding post 1501 that slides and engages with the second drive groove group is fixedly installed on the second incomplete gear 15.

[0075] As a further embodiment of this utility model, the first driving groove group includes a first spiral groove 1201 and a first vertical groove 1202; one end of the first spiral groove 1201 is connected to one end of the first vertical groove 1202; the second driving groove group includes a second vertical groove 1203 and a second spiral groove 1204; one end of the second vertical groove 1203 is connected to one end of the second spiral groove 1204.

[0076] In this embodiment, when the piston 11 slides away from the vessel body 1 under the pressure of the gas inside the vessel body 1, the slide rod 12 moves synchronously, thereby causing the first protruding column 1401 and the second protruding column 1501 to slide in the first drive groove group and the second drive groove group respectively.

[0077] The first protruding post 1401 will first slide in the first spiral groove 1201 to squeeze the first protruding post 1401 through the groove wall of the first spiral groove 1201, thereby driving the first incomplete gear 14 to rotate, thereby driving the first gear 5 to rotate through meshing; during this process, the second protruding post 1501 will slide in the second vertical groove 1203, at which time the second incomplete gear 15 will not rotate.

[0078] The rotation angle of the first gear 5 is directly proportional to the sliding distance of the first protruding column 1401 in the first spiral groove 1201; and the sliding distance of the first protruding column 1401 in the first spiral groove 1201 is directly proportional to the sliding distance of the piston 11 pushed by the gas pressure. Therefore, the greater the increase in pressure inside the reactor, the greater the rotation angle of the sealing plate 6, which makes the conduction area of ​​the gas inlet pipe 3 smaller and smaller, and the replenishment rate of chlorine gas lower, thereby slowing down and stabilizing the reaction process.

[0079] When the first protruding post 1401 slides into the first vertical groove 1202, the sealing plates 6 abut against each other to block the air intake pipe 3.

[0080] At this point, as the pressure inside the reactor continues to increase, the piston 11 will continue to slide. This causes the first protruding column 1401 to slide in the first vertical groove 1202. At this time, the first incomplete gear 14 does not rotate to maintain the blocked state of the air inlet pipe 3. Simultaneously, the second protruding column 1501 will slide in the second spiral groove 1204. Through the squeezing action of the groove wall of the second spiral groove 1204 on the second protruding column 1501, the second incomplete gear 15 will rotate, and through meshing, it will drive the second gear 9 to rotate, thereby gradually opening the first pressure relief hole 801 to relieve pressure on the reactor and avoid the occurrence of dangerous accidents.

[0081] The induction structure senses the pressure changes inside the reactor in real time and alternately drives the flow conversion structure and the pressure relief structure according to the pressure change. This reduces the replenishment rate of chlorine gas by reducing the conduction area of ​​the inlet pipe 3, thereby slowing down and stabilizing the reaction process. When the pressure inside the reactor is too high, the first pressure relief hole 801 is opened to reduce the pressure inside the reactor, thereby ensuring the safe operation of the reactor.

[0082] As a further improvement of this utility model, multiple pressure gauges are fixedly installed on the vessel cover 2, and the pressure gauges are used to accurately observe the pressure changes inside the vessel body 1.

[0083] In this embodiment, a pressure gauge is used to accurately detect pressure changes inside the reactor, and the chlorination reaction is precisely adjusted based on the pressure change value, which can effectively improve the efficiency of the chlorination reaction and the quality of the finished product.

[0084] As a further embodiment of this utility model, multiple diversion pipes 4 are fixedly installed at the end of the intake pipe 3; multiple exhaust valves 401 are fixedly installed on the diversion pipes 4.

[0085] In this embodiment, the chlorine gas is diverted through the diversion pipe 4 and discharged into the vessel 1 through the exhaust valve 401, which can effectively increase the contact time between chlorine gas and reactants and slow down the rate of chlorine gas entry, thereby improving the efficiency of the chlorination reaction and the quality of the finished product.

[0086] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
