[0002] Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc. The internal heating of the reactor can be carried out by direct heating and indirect heating. Direct heating is to directly heat the bottom and cylinder of the reactor, and indirect heating is to use gas or liquid heat carrier to heat the reactor. Indirectly heated reactors usually have various forms of heat transfer structures, such as ordinary jackets and half-tube jackets on the outside of the reactor body, and coils (coils) inside the reactor body. In the indirect heating process, only the temperature inside the coil can be heated and cooled, but the temperature cannot be quickly regulated and kept constant within the required temperature range, which affects the heating efficiency of the reactor.

[0025] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0026] A temperature control device for a reactor, comprising a heating furnace 1, a controller 2 is installed at a corner of the top of the heating furnace 1, a liquid storage tank 3 is installed at one end of the heating furnace 1, an upper liquid pipe 4 is connected to the top of the heating furnace 1, a liquid outlet pipe 5 is connected to the bottom of the outer side of the heating furnace 1, a first flow control valve 6 is sleeved and installed on the outer ring surface of the liquid outlet pipe 5, a tee pipe 7 is connected to one end of the liquid outlet pipe 5, a cold liquid pipe 9 is connected to one side of the outer ring surface of the tee pipe 7, a temperature sensor 8 is installed on the top of the tee pipe 7, a second flow control valve 10 is sleeved and installed on the outer ring surface of the cold liquid pipe 9, and a bend pipe 11 is connected to one end of the tee pipe 7;

[0027] One end of the curved pipe 11 is connected to a circulation pump 12, the discharge port of the circulation pump 12 is connected to a liquid inlet pipe 13, one end of the liquid inlet pipe 13 is connected to a copper coil 14, the liquid outlet of the copper coil 14 is connected to a liquid return pipe 15, and a first electrically controlled valve 16 and a second electrically controlled valve 17 are respectively installed on two joints at one end of the liquid return pipe 15.

[0028] For example, please refer to Figure 1 , Figure 2 and Figure 3 , the controller 2 is electrically connected to the first flow control valve 6, the temperature sensor 8, the second flow control valve 10, the circulating pump 12, the first electric control valve 16 and the second electric control valve 17, and the controller 2 is provided with a display panel and a control button. The display panel on the controller 2 is used to display the temperature detected by the temperature sensor 8, and the control button is used to set the program for each device;

[0029] The first flow control valve 6 and the second flow control valve 10 are opened and closed in inverse proportion. The greater the opening and closing degree of the first flow control valve 6 is, the more the second flow control valve 10 is closed in the same proportion. The first flow control valve 6 and the second flow control valve 10 control the liquid output of the liquid outlet pipe 5 and the cold liquid pipe 9 to always maintain the output flow of one pipeline. The liquid outlet pipe 5, the cold liquid pipe 9 and one end of the elbow 11 are all connected inside the three-way pipe 7, and the liquid temperature inside the three-way pipe 7 is detected by the temperature sensor 8. During the temperature control process, when the temperature of the mixed liquid entering the three-way pipe 7 through the liquid outlet pipe 5 and the cold liquid pipe 9 is controlled to be the set temperature, it means that the set requirement is met, and the opening and closing degree of the first flow control valve 6 and the second flow control valve 10 at this time is maintained.

[0030] For example, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the circulation pump 12 transports the liquid inside the three-way pipe 7 to the liquid inlet pipe 13 through the elbow 11, and then transports it into the copper coil 14. After the copper coil 14 is filled with heat-conducting liquid, it is discharged through the return liquid pipe 15. The copper coil 14 has one end for liquid inlet and one end for liquid discharge to form a liquid circulation. The first electric-controlled valve 16 is installed on the liquid storage tank 3, and the second electric-controlled valve 17 is installed on the heating furnace 1. At the same time, the first electric-controlled valve 16 and the second electric-controlled valve 17 are connected to the liquid storage tank 3 and the heating furnace 1 respectively. When the temperature is lowered, the first electric-controlled valve 16 is opened and the second electric-controlled valve 17 is closed. When the temperature is raised, the second electric-controlled valve 17 is opened and the first electric-controlled valve 16 is closed, so as to avoid low-temperature liquid from entering the heating furnace 1 during temperature reduction to increase energy consumption loss;

[0031] One end of the upper liquid pipe 4 extends into the inner bottom end of the liquid storage tank 3, and the liquid storage tank 3 is connected with the interior of the heating furnace 1 through the upper liquid pipe 4. When the liquid inside the heating furnace 1 is lost, the heat-conducting liquid inside the liquid storage tank 3 can be added into the heating furnace 1 through the upper liquid pipe 4.

[0032] Among them, the controller 2, the first flow control valve 6, the temperature sensor 8, the second flow control valve 10, the circulation pump 13, the first electric control valve 16 and the second electric control valve 17 are existing technologies, and their structural principles are not repeated here.

[0033] The working process of the utility model: using a temperature control device for a reactor designed by the present invention, when the device is used to heat the reactor, the heat-conducting liquid inside the heating furnace 1 is first heated to a certain temperature, and then transported to the three-way pipe 7 through the liquid outlet pipe 5, and then circulated to the elbow 11 to enter the circulation pump 12. The circulation pump 12 is injected into the copper coil 14 through the liquid inlet pipe 13 to increase the temperature of the copper coil 14 and then heat the reactor. After the copper coil 14 is filled with heat-conducting liquid, it flows out through the return liquid pipe 15. At this time, the first electric control valve 16 is closed, and the second electric control valve 17 is opened, so that the heat-conducting liquid returns to the heating furnace 1. At this time, although the temperature of the refluxed heat-conducting liquid is lowered, The required temperature can be heated in the heating furnace 1. However, when the heating temperature of the copper coil 14 needs to be set and controlled, the temperature is first set on the controller 2, for example, the temperature is lowered to a certain degree to start constant temperature. At this time, the first flow control valve 6 is gradually closed and the second flow control valve 10 is gradually opened. At this time, the high-temperature heat-conducting liquid and the room-temperature liquid in the cold liquid pipe 9 are mixed, and their temperatures are detected by the temperature sensor 8. When the temperature reaches the set value, the opening and closing degree of the first flow control valve 6 and the second flow control valve 10 are fixed. At this time, the heat-conducting liquid with the set temperature can be input into the copper coil 14 to keep the temperature of the copper coil 14 constant, thereby meeting different degrees of heating needs.

[0034] In summary, the device is set up to regulate the heating temperature in the reactor. After the temperature is set according to needs, the device automatically adjusts to the set temperature and maintains a constant temperature to heat the inside of the reactor.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
