[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a safe chemical reactor with the following features:

[0015] Beneficial effects:

[0016] 1. This safe chemical reactor uses a pressure relief component. When the pressure in the reaction body exceeds the set range, the pressure switch detects that the pressure in the detection tube exceeds the set range and then controls the pressure relief valve to start. The pressure relief valve controls the flow guide ends on the lower sides of the two groups of three-way branch pipes to be connected. The raw materials in the reaction body enter the neutralization component through the flow guide pipe, the three-way branch pipe and the pressure relief valve. In this process, the pressure in the device is effectively reduced, the safety of the device during operation is effectively improved, and the practicability of the device is enhanced.

[0017] 2. The safe chemical reactor uses a neutralization component to allow personnel to select the corresponding neutralizing liquid according to the type of chemical reaction in the reaction body. After the neutralizing liquid is selected, it is injected into the neutralization component through the liquid inlet valve and the guide pipe. After the raw materials in the reaction body enter the neutralization component through the pressure relief component, the neutralizing liquid reacts with it to slow down the original chemical reaction, which effectively increases the upper limit of the device's load capacity and greatly reduces the probability of losses caused by subsequent chemical reactions in the device, thereby enhancing the applicability of the device.

[0018] 3. This safe chemical reactor uses forced components. When the pressure switch or pressure relief valve fails abnormally, the pressure generated in the chemical reaction in the reaction body acts on the crushing plate through the guide pipe and the three-way branch pipe. When the pressure exceeds the upper limit of the crushing plate, it controls the connection of the guide ends on the upper sides of the two sets of three-way branch pipes through its own damage, which effectively improves the adaptability of the device to different conditions, further improves the safety of the device, and thus enhances the practicability of the device.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

After the raw materials in the reaction body 1 enter the neutralization component 4 through the pressure relief component 9, the neutralization liquid reacts with it to slow down the original chemical reaction, which effectively improves the upper limit of the load of the device and greatly reduces the subsequent chemical reaction in the device. The probability of causing loss should be reduced, thereby enhancing the applicability of the device. The neutralization component 4 includes two groups of neutralization end covers 5, and a neutralization cylinder 6 is fixedly installed between the two groups of neutralization end covers 5 by bolts and nuts.

The outer surfaces of the kettle body 2 and the neutralization cylinder 6 are both connected with a guide pipe 8, and the two groups of guide pipes 8 are connected with a pressure relief component 9 through bolts and nuts. Through the pressure relief component 9, when the pressure in the reaction body 1 exceeds the set range, the pressure switch 13 detects that the pressure in the detection tube 12 exceeds the set range and then controls the pressure relief valve 11 to start, and the pressure relief valve 11 The guide ends of the lower sides of the two groups of three-way branch pipes 10 are controlled to be connected, and the raw materials in the reaction body 1 enter the neutralization component 4 through the guide pipe 8, the three-way branch pipe 10 and the pressure relief valve 11. In this process, the pressure in the device is effectively reduced, and the safety of the device operation process is effectively improved, thereby enhancing the practicality of the device. The pressure relief component 9 includes two groups of three-way branch pipes 10, and the guide ends on the lower sides of the two groups of three-way branch pipes 10 are connected with the pressure relief valve 11.

Through the forced component 14, when the pressure switch 13 or the pressure relief valve 11 fails abnormally, the pressure generated in the chemical reaction in the reaction body 1 acts on the crushing plate 16 through the guide pipe 8 and the three-way branch pipe 10. After the pressure exceeds the upper limit of the crushing plate 16, it controls the connection of the guide ends on the upper sides of the two groups of three-way branch pipes 10 through its own damage, which effectively improves the adaptability of the device to different conditions, further improves the safety of the device, and thus enhances the practicality of the device. The forced component 14 includes two groups of covering rings 15, which are fixed and installed by bolts and nuts, and a crushing plate 16 is arranged between the two groups of covering rings 15.

[0027] In the utility model, in order to improve the convenience during the lifting and transportation of the device, a plurality of groups of lifting supports 21 for providing lifting positions during the lifting and transportation of the device are provided on the outer surfaces of the kettle body 2 and the neutralization cylinder 6, and lifting holes are provided on the outer surface of each group of lifting supports 21, thereby improving the convenience during the lifting and transportation of the device.

The material of the barrier lining is polytetrafluoroethylene, thereby reducing the probability of long-term corrosion of the neutralizing liquid in the neutralizing component 4.

[0030] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0031] When in use, the device is first fixedly installed at the set position. After the device is installed, the raw materials in the reaction body 1 undergo a chemical reaction operation. During this process, the corresponding neutralizing liquid is injected into the neutralization component 4 through the liquid inlet valve 22 and the guide pipe 8. When the pressure in the reaction body 1 exceeds the set range, the pressure switch 13 detects that the pressure in the detection tube 12 exceeds the set range and then controls the pressure relief valve 11 to start. The pressure relief valve 11 controls the connection of the guide ends on the lower sides of the two groups of three-way branch pipes 10. The raw materials in the reaction body 1 enter the neutralization component 4 through the guide pipe 8, the three-way branch pipe 10 and the pressure relief valve 11. At this time, the neutralizing liquid in the neutralization component 4 reacts with the raw materials to slow down the original chemical reaction. When the pressure switch 13 or the pressure relief valve 11 fails abnormally, the pressure generated in the chemical reaction in the reaction body 1 acts on the crushing plate 16 through the guide pipe 8 and the three-way branch pipe 10. After the pressure exceeds the upper limit of the crushing plate 16, it controls the connection of the guide ends on the upper sides of the two groups of three-way branch pipes 10 through its own damage.
