Description

Technical Field

[0001] The utility model relates to the technical field of cooling facilities for chemical reaction kettles, in particular to a rapid cooling mechanism for chemical reaction kettles. Background Art

[0002] In the process of chemical production, the reaction kettle is a key device for realizing physical or chemical reactions. In some processes, rapid cooling is a necessary step. For example, in synthesis, polymerization or distillation processes, controlling the reaction rate and product quality. Technological progress has promoted the innovation of chemical equipment, including the design and application of rapid cooling mechanisms. By adopting new materials, new processes and intelligent control systems, the efficiency and safety of chemical production have been improved.

[0003] In the prior art, with the strengthening of safety production regulations, chemical enterprises face higher and higher safety requirements in the production process. As the main equipment for chemical reactions, the safe operation of chemical reaction kettles is crucial. Under high-temperature conditions, violent reactions may occur in the reaction kettle, even leading to explosions, causing casualties and property losses. The reactions in chemical reaction kettles are often accompanied by the release of heat. If the heat cannot be removed in time, it may lead to out-of-control temperature, triggering side reactions or even explosions. Therefore, temperature control is the key to ensuring the safe operation of the reaction kettle. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a rapid cooling mechanism for chemical reaction kettles.

[0005] To achieve the above object, the utility model adopts the following technical solutions: It includes a reaction chamber, and a cooling device is arranged on the outer wall of the reaction chamber. The cooling device includes a cooling chamber, a heat dissipation outer shell is fixed inside the cooling chamber, a water condensation pipe is fixed inside the heat dissipation outer shell, a heat exchange pipe is fixed at one end of the water condensation pipe, an annular outer shell is fixed on the outer wall of the reaction chamber, a heat dissipation plate is fixed on the inner wall of the heat dissipation outer shell, a wind direction fan is rotatably connected inside the heat dissipation plate, an expansion water tank is fixed at the bottom of the heat dissipation outer shell, and heat dissipation slots are opened on both end faces of the heat dissipation outer shell. In the prior art, with the strengthening of safety production regulations, chemical enterprises face higher and higher safety requirements during the production process. As the main equipment for chemical reactions, the safe operation of chemical reaction kettles is of crucial importance. Under high-temperature conditions, violent reactions may occur inside the reaction kettle, even leading to explosions, causing casualties and property losses. The reactions in chemical reaction kettles are often accompanied by the release of heat. If the heat cannot be removed in time, it may lead to out-of-control temperature, triggering side reactions or even explosions. Therefore, temperature control is the key to ensuring the safe operation of the reaction kettle. By installing a cooling device, when a chemical reaction kettle generates high heat during the reaction, the cooling device is activated, and the internal expansion water tank is activated to make the high-specific heat capacity liquid in the cooling device flow along a fixed direction, pass through the water condensation pipe and the heat exchange pipe, absorb the high heat in the reaction kettle, and then the high-temperature liquid inside flows to the cooling device. After conversion by the expansion water tank and rotation of the wind direction fan, the internal heat is dissipated, and it continues to flow to the heat exchange pipe as low-temperature and low-pressure liquid to form a cycle, thereby achieving rapid cooling of the reaction kettle.

[0006] Preferably, a pressure valve device is fixed on the top of the reaction chamber. A connection port is fixed on the inner wall of the pressure valve device. A sealing valve is slidably connected to the inner wall of the air valve housing. A conical platform is fixed on the inner wall of the air valve housing. An air release port penetrates through the outer wall of the air valve housing. A sealing nut is threadedly connected to the bottom of the conical platform. In the prior art, chemical reaction kettles are equipment used for chemical reactions in chemical production. They are usually designed to withstand a certain pressure and temperature. However, in some cases, the reactions inside the reaction kettle may generate high-temperature and high-pressure gases. If the reaction rate is too fast, it may cause the temperature and pressure to rise rapidly, which may lead to safety problems, including the rupture or explosion of the reaction kettle. The utility model installs a gas valve device on the top of the reaction chamber. When high-pressure gas passes through the gas valve device, the gas pushes the sealing valve through the connection port, causing it to move. Then the high-pressure gas flows out through the air release port, reducing the internal gas pressure, thereby achieving rapid pressure reduction and avoiding explosion due to excessive internal pressure.

[0007] Preferably, a protective sleeve is provided on the inner wall of the annular outer shell to prevent damage to the heat exchange pipe caused by vibration of the device during chemical reactions.

[0008] Preferably, the cross-section of the heat dissipation slot is V-shaped, so as to reduce the entry of dust during the heat dissipation process.

[0009] Preferably, a heat insulation protection layer is provided on the outer wall of the water condensation pipe, so as to reduce the heat loss during the transportation of the coolant.

[0010] Preferably, a rubber sleeve is sleeved on the surface of the sealing nut, so as to increase the comfort of the user, avoid slipping, and thus reduce hand fatigue and potential work injury risks.

[0011] Preferably, the diameter of the frustum is larger than the inner diameter of the air valve housing, so as to further improve the pushing rate of the gas to push the sealing valve.

[0012] Beneficial effects

[0013] 1. In the prior art, with the strengthening of safety production regulations, chemical enterprises face higher and higher safety requirements during the production process. As the main equipment for chemical reactions, the safe operation of chemical reaction kettles is crucial. Under high-temperature conditions, violent reactions may occur in the reaction kettle, even leading to explosions, causing casualties and property losses. The reactions in chemical reaction kettles are often accompanied by the release of heat. If the heat cannot be removed in time, it may lead to out-of-control temperature, trigger side reactions or even explosions. Therefore, temperature control is the key to ensuring the safe operation of the reaction kettle. By installing a cooling device, when a chemical reaction kettle generates high heat during a reaction, the cooling device is activated, and the internal expansion water tank is activated. The high-specific heat capacity liquid in the cooling device flows along a fixed direction, passes through the water condensation pipe and the heat exchange pipe, absorbs the high heat in the reaction kettle, and then the internal high-temperature liquid flows to the cooling device. After the conversion of the expansion water tank and the rotation of the wind fan, the internal heat is dissipated, and it continues to become a low-temperature and low-pressure liquid and flows to the heat exchange pipe to form a cycle, so as to achieve rapid cooling of the reaction kettle.

[0014] 2. In the prior art, chemical reaction kettles are equipment used for chemical reactions in chemical production, and they are usually designed to withstand a certain pressure and temperature. However, in some cases, the reactions in the reaction kettle may generate high-temperature and high-pressure gases. If the reaction rate is too fast, it may cause the temperature and pressure to rise rapidly, which may lead to safety problems, including the rupture or explosion of the reaction kettle. The utility model installs an air valve device at the top of the reaction chamber. When high-pressure gas passes through the air valve device, the gas pushes the sealing valve through the connection port, causing it to be pushed. Then the high-pressure gas flows out through the air release port, reducing the pressure inside the gas, so as to achieve rapid pressure reduction and avoid explosion due to excessive internal pressure.
