[0005] In order to improve the cooling efficiency of a reactor, the present application provides a rapid cooling system for a reactor.

[0006] The present application provides a rapid cooling system for a reactor, which adopts the following technical solution:

[0007] A rapid cooling system for a reaction kettle comprises a kettle body, a spray chamber and a first water supply component, wherein the kettle body is located in the spray chamber, a plurality of spray heads are arranged in the spray chamber, each of the spray heads is distributed along the circumference of the kettle body and faces the outer wall of the kettle body, each of the spray heads is connected to the first water supply component, a ventilation port is provided at the top of the spray chamber, and an exhaust fan is arranged in the ventilation port.

[0008] By adopting the above technical solution, when the kettle body needs to be cooled, the first water supply component supplies water to each spray head, and each spray head sprays water on the kettle body in the spray chamber to reduce the temperature of the kettle body. The hot air in the spray chamber can be output from the spray chamber through the ventilation port, thereby accelerating the heat dissipation of the spray chamber and improving the cooling efficiency of the kettle body.

The drain pipe can transport the water in the spray chamber to the water tank for storage. The stirring assembly can stir the water in the water tank to cool the water in the water tank. The heat in the water tank can be discharged through the heat dissipation port.

[0018] By adopting the above technical scheme, the fan can bring the air outside the spray room into the spray room through the air inlet, thereby improving the ventilation of the spray room and facilitating the heat dissipation of the kettle body. When the spray head sprays water on the kettle body, the water baffle plate can block water from the air inlet, thereby avoiding the spray water from entering the air inlet as much as possible, and the spray water falling on the water baffle plate can slide along the water baffle plate to the bottom of the spray room.

[0026] 3. The temperature detection component can detect the water temperature in the water tank.
