[0029] The condensing mechanism 200 comprises an inner shell 201 fixedly connected to the inner wall of the shell 103, the top of the inner shell 201 is communicated with a reactor opening 202, the surface of the inner shell 201 is communicated with a pressure relief valve 203, the inner cavity of the inner shell 201 is provided with a heat exchange assembly 204, and the supporting plate 105 is provided with a heat dissipation assembly 205 used in cooperation with the heat exchange assembly 204.

[0030] The heat exchange assembly 204 comprises a heat exchanger 204a adaptively installed on the side wall of the inner shell 201, and the other end of the heat exchanger 204a extends to the inner cavity of the inner shell 201.

[0031] Specifically, the heat exchanger 204a is in a hollow cylindrical shape, and the bottom is fixedly installed on the inner wall of the inner shell 201, so that the condensation is ensured when the inner shell 201 is reacting.

[0032] The bottom of the heat exchanger 204a is communicated with a water guide pipe 204b, the water guide pipe 204b is sleeved on the side wall of the inner shell 201, the end of the water guide pipe 204b is fixedly connected with a water outlet pipe 204c, and the top of the heat exchanger 204a is communicated with a water inlet pipe 204d.

[0033] Further, the water guide pipe 204b is in a spiral shape and is uniformly wound on the side wall of the inner shell 201, and cooperates with the heat exchanger 204a and the shell 103 to further cool the inner shell 201.

[0034] The heat dissipation assembly 205 comprises a water inlet 205a communicated at the end of the water outlet pipe 204c, the other end of the water inlet 205a is fixedly connected with a heat dissipation pipe 205b, and the surface of the heat dissipation pipe 205b is sleeved with a heat dissipation fin 205c.

[0035] Preferably, the heat dissipation pipe 205b is in a disc stack shape, the outer surface of the heat dissipation pipe 205b is sleeved with a plurality of heat dissipation fins 205c, the heat dissipation pipe 205b and the heat dissipation fin 205c are made of aluminum material, the heat dissipation efficiency is improved, and the temperature is more easily reduced.

[0036] The side wall of the heat dissipation fin 205c is fixedly connected with a heat dissipation shell 205d, the heat dissipation shell 205d is adaptively installed with a fan 205e on the side wall, the end of the heat dissipation pipe 205b is communicated with a transfer pipe 205f, the other end of the transfer pipe 205f is communicated with a water tank 205g, the side wall of the water tank 205g is communicated with a centrifugal pump 205h, and the water outlet of the centrifugal pump 205h is communicated with the water inlet pipe 204d.

The outer shell 103 protects the water guide pipe 204b, and the pressure relief valve 203 ensures that the pressure in the inner shell 201 does not exceed the threshold.

[0039] In summary, through the continuous work of the centrifugal pump 205h, the circulation of the cooling water is effectively realized, the high-efficiency heat exchange of the heat exchanger 204a is ensured, and the cooling efficiency is significantly improved.

The protection of the outer shell 103 to the water guide pipe 204b and the setting of the pressure relief valve 203 not only enhance the safety of the system, but also avoid the risk that the pressure in the inner shell 201 may exceed the threshold, thereby improving the reliability and operation efficiency of the device as a whole.
