[0017] The preferred embodiments of the utility model are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0018] Embodiment: as Figs. 1-2As shown, the utility model discloses a kind of anti-fouling reactors, including reactor body 1, first liquid inlet 2 and second liquid inlet 3 are provided on reactor body 1, first liquid inlet 2 is arranged on the lateral wall of reactor body 1, second liquid inlet 3 is arranged on the top of reactor body 1, the bottom of reactor body 1 is provided with liquid outlet 4, the inside of reactor body 1 is provided with elastic inner cavity 11, by setting elastic inner cavity 11, it can use the deformation and friction generated by the relaxation and contraction of high-elasticity inner cavity 11 inner wall, to remove the scale adhered on the inner wall of elastic inner cavity 11, it is more convenient to use.Elastic inner cavity 11 is provided with air inlet 6, reactor body 1 is provided with protective hole 5, air inlet 6 is sleeved in the inside of protective hole 5.

[0019] Air inlet 6 is provided with air inlet assembly, air inlet assembly includes air inlet pipe 9, one end of air inlet pipe 9 is fixedly connected in air inlet 6, the other end of air inlet pipe 9 is fixedly connected with air pump 10, air inlet pipe 9 is fixedly connected with pressure relief valve.By setting air pump 10 and air inlet pipe 9, air pump 10 can be more conveniently used to pressurize the inside of elastic inner cavity 11, and the pressure relief valve fixedly connected on air inlet pipe 9 can also be more conveniently used to relieve the internal pressure of elastic inner cavity 11, which is more conducive to the relaxation and contraction of elastic inner cavity 11, thereby improving the anti-fouling ability of reactor body 1.

[0020] Elastic inner cavity 11 is provided with pressure monitoring assembly, and the pressure monitoring assembly includes air pressure sensor 8.By setting air pressure sensor 8, the gas pressure in the inside of elastic inner cavity 11 can be more conveniently monitored, and the internal pressure of elastic inner cavity 11 can also be further prevented from being too high to cause safety accidents, thereby improving the safety performance of the reaction;Reactor body 1 is provided with connecting hole 7, and connecting pipe is fixedly connected to elastic inner cavity 11, and one end of the connecting pipe away from elastic inner cavity 11 is fixedly connected between connecting hole 7 and air pressure sensor 8.

[0021] Cavity 12 is arranged between the inner wall of elastic inner cavity 11 and reactor body 1;By setting cavity 12 between elastic inner cavity 11 and the inner wall of reactor body 1, elastic inner cavity 11 can be more conveniently relaxed, so that scale can be more conveniently prevented from adhering to the inner wall of elastic inner cavity 11.

[0022] Sealing pad is fixedly connected at the connection of air inlet pipe 9 and air inlet 6;Sealing ring is fixedly connected at the connection of connecting pipe and air pressure sensor 8 in connecting hole 7;Both the sealing pad fixedly connected at the connection of air inlet pipe 9 and air inlet 6 and the sealing ring fixedly connected at the connection of connecting pipe and air pressure sensor 8 in connecting hole 7 can effectively improve the sealing performance of the inside of reactor body 1, so that the pressurization and pressure relief operation of the inside of elastic inner cavity 11 can be more conveniently performed.

[0023] In operation, during the liquid-liquid reaction, when it is necessary to prevent the scaling on the inner wall of the liquid-liquid reactor body 1, the inside of the elastic inner cavity 11 is pressurized by the air pump 10 and the air inlet pipe 9, and the air pressure in the elastic inner cavity 11 is monitored by the air pressure sensor 8 fixedly connected with the elastic inner cavity 11. During the pressurization of the inside of the elastic inner cavity 11, the inner wall of the elastic inner cavity 11 is in a relaxed state. When the air pressure sensor 8 monitors that the air pressure in the elastic inner cavity 11 reaches a set value, the air pressure sensor 8 converts the pressure signal into an electric signal and sends it to the external PLC controller. The signal processing module in the PLC controller processes the received pressure monitoring signal, and the processed data is transmitted to the controller through the communication interface. At this time, the controller controls the pressure relief valve to release pressure. When the pressure relief valve releases pressure, the inner wall of the elastic inner cavity 11 is in a contracted state. By using the relaxation and contraction of the elastic inner cavity 11, it periodically contracts and relaxes during the reaction process. This periodic action can interfere with the formation of scaling and reduce the adhesion strength of scaling. At the same time, the material may generate a certain friction force during the relaxation and contraction process, thereby helping to remove the scaling layer that has begun to form, and thus also has a certain degree of self-cleaning property, making it more convenient to use.
