Description

Technical Field

[0001] The utility model belongs to the technical field of reactors, and particularly relates to a cooling water circulation system of a reactor. Background Art

[0002] A reactor is a container used for chemical reactions and is widely used in the chemical, pharmaceutical, food processing, and material synthesis industries. The reactor's cooling water system is used to control and maintain the reactor's temperature during the chemical reaction and is a crucial component of chemical production.

[0003] In the related art, when the cooling water system of the reactor is cooled down simultaneously on multiple production lines, excessive flow of the cooling water pump can easily cause system overcurrent. When the inverter overcurrent protection pump stops secretly, the operator cannot discover it in time, which can easily cause the reaction to overheat during the droplet addition process and affect product quality.

DETAILED DESCRIPTION

[0021] The present invention can be more easily understood by referring to the following detailed description of the preferred embodiments of the present invention and the included Examples. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which the present invention belongs. In the event of any conflict, the definitions in this specification shall prevail.

[0022] Example 1:

[0023] Provides the following for completion Figure 1-2 The cooling water circulation system of a reactor shown includes: a cooling device 1, a cooling water circulation pipeline 2, and a reactor 3. The reactor 3 is connected to the cooling device 1 through the cooling water circulation pipeline 2. A cooling water pump 4 is provided on the cooling water circulation pipeline 2, and the cooling water pump 4 is electrically connected to the reactor 3.

[0024] The cooling device 1 includes a cooling tower 11 and a cooling water tank 12 . The cooling tower 11 is above the cooling water tank 12 , and the cooling tower 11 is communicated with the cooling water tank 12 .

[0025] The cooling water circulation pipeline 2 includes a cooling water inlet pipe 21 and a cooling water return pipe 22. The cooling water inlet pipe 21 is connected to the cooling water tank 12, and the cooling water return pipe 22 is connected to the cooling tower 11. The cooling water pump 4 is provided on the cooling water inlet pipe 21.

[0026] Reactor 3 is equipped with several units. Reactor 3 is provided with a water inlet 31 and a water return port 32. The water inlet 31 is connected to the cooling water inlet pipe 21, and the water return port 32 is connected to the cooling water return pipe 22. Reactor 3 is provided with a condenser 33, which is connected to reactor 3. Condenser 33 is connected to cooling water inlet pipe 21 and cooling water return pipe 22. Reactor 3 is also provided with an agitator 34.

[0027] The reactor 3 further comprises a controller 5, which is electrically connected to the agitator 34 and the cooling water pump 4 of the reactor 3. The controller 5 is used to detect the operating frequency of the cooling water pump 4 and whether the agitator 34 is started normally, thereby determining whether the cooling water pump 4 is working normally.

[0028] The system also includes an alarm 6 , which is electrically connected to the controller 5 .

[0029] Working principle: The cooling water pump 4 causes the cooling water in the cooling water tank 12 to flow out from the cooling water inlet pipe 21 and enter the reactor 3 to cool the reactor 3. The heated cooling water then returns to the cooling tower 11 from the cooling water return pipe 22. The cooling tower 11 cools the cooling water and then enters the cooling water tank 12, thus realizing the cooling water circulation.

[0030] When there are many reactors 3, the cooling water pump 4 has an excessive flow rate, which can easily cause system overcurrent. The inverter in the cooling water pump 4 protects the pump from stopping secretly. At this time, the frequency of the cooling water pump 4 is 0 Hz. The controller 5 detects that the frequency of the cooling water pump 4 is 0 Hz and has not recovered for a period of time, and that the agitator 34 of the reactor 3 is running. It determines that the cooling system is abnormal and issues an alarm through the alarm 6. When the controller 5 detects that the agitator 34 of the reactor 3 is not running, it determines that the cooling water circulation system is not started and does not issue an alarm.
