[0054] The above technical scheme has the following working principle:

[0055] When the temperature needs to be raised, the first adjusting valve 201 on the first branch of the supply pipeline 2 is opened, and the second adjusting valve 202 on the second branch of the supply pipeline 2 is closed; at the same time, the first switch valve 301 on the first branch of the discharge pipeline 3 is opened, and the second switch valve 303 on the second branch of the discharge pipeline 3 is closed, and the flow path is as follows:

[0056] The industrial steam enters the medium inlet of the heat exchanger 1 through the first branch of the supply pipeline 2, and then exchanges heat with the temperature adjusting medium inside the heat exchanger 1, and the condensed water formed after heat exchange enters the discharge pipeline 3 from the medium outlet of the heat exchanger 1, and then is discharged through the first branch of the discharge pipeline 3, wherein the steam leakage through the pipeline is prevented by the trap valve 302 to avoid heat waste.

[0057] When the temperature needs to be lowered, the first adjusting valve 201 on the first branch of the supply pipeline 2 is closed, and the second adjusting valve 202 on the second branch of the supply pipeline 2 is opened; at the same time, the first switch valve 301 on the first branch of the discharge pipeline 3 is closed, and the second switch valve 303 on the second branch of the discharge pipeline 3 is opened, and the flow path is as follows:

[0058] The cooling water enters the medium inlet of the heat exchanger 1 through the second branch of the supply pipeline 2, and then exchanges heat with the temperature adjusting medium inside the heat exchanger 1, and then enters the discharge pipeline 3 from the medium outlet of the heat exchanger 1, and then is discharged through the second branch of the discharge pipeline 3.

[0059] When the temperature of the temperature adjusting medium is adjusted, the circulating pump 501 on the input pipeline 5 is started, and the first cut-off valve 601 on the output pipeline 6 is opened, and the second cut-off valve 701 on each branch of the temperature adjusting pipeline 7 is closed, and the flow path is as follows:

[0060] The temperature adjusting medium in the input pipeline 5 will enter the water inlet of the heat exchanger 1 under the pumping of the circulating pump 501, then exchange heat with industrial steam or cooling water in the heat exchanger 1, and then enter the water outlet of the heat exchanger 1 to enter the output pipeline 6 and then enter the buffer tank 4 for storage, and finally return to the input pipeline 5, so as to form an internal circulation temperature adjusting loop, so that the temperature of the temperature adjusting medium can be fully adjusted.

[0061] When the internal temperature of a certain reactor is adjusted, the second cut-off valve 701 on the branch of the temperature adjusting pipeline 7 connected with the reactor is opened, and the first cut-off valve 601 is closed, and the flow path is as follows:

[0062] The temperature adjusting medium in the output pipeline 6 will enter the temperature adjusting pipeline 7, then enter the temperature adjusting cavity of the reactor through the corresponding branch, so as to heat or cool the reactor, then return to the output pipeline 6 through the return pipeline 8, then enter the heat exchanger 1 through the buffer tank 4 and the input pipeline 5 in turn, and finally return to the output pipeline 6, so as to form an external circulation loop.

[0063] The utility model discloses a heat exchanger 1, buffer tank 4 and circulating pump 501 etc. component, realize accurate, efficient and flexible adjustment of the temperature of multiple reactors, meet the strict requirement of different chemical reactions to temperature control, and can carry out waste heat recovery to industrial steam, thereby greatly reduce energy consumption, reduce production cost, improve energy saving and environmental protection effect.

[0064] In some embodiments, such as Figure 1 Further comprising: a blowdown pipeline 9 in series with a first stop valve 901, and one end is connected with the input pipeline 5, and the communication point is located between the circulating pump 501 and the buffer tank 4. Wherein, the input pipeline 5 is in series with a second stop valve 502, and the second stop valve 502 is located between the heat exchanger 1 and the circulating pump 501.

[0065] When the temperature adjusting medium in the buffer tank 4 needs to be discharged, the second stop valve 502 is closed, and the first stop valve 901 is opened, so that the temperature adjusting medium in the buffer tank 4 will enter the input pipeline 5, and then be discharged through the blowdown pipeline 9.

[0066] Through the above setting, the buffer tank 4 can be conveniently and quickly emptied, so that it is convenient to maintain and maintain, improve the maintenance efficiency, and will not interfere with other parts of the system, and the operation stability is guaranteed.

[0067] In some embodiments, such as Figure 1Further comprising: a water inlet pipeline 10 and a buoyancy valve 11; wherein the water inlet pipeline 10 is connected in series with a first on-off valve 1001, and one end of the water inlet pipeline 10 is connected in communication with the water supplementing port of the buffer tank 4; the buoyancy valve 11 is installed in the buffer tank 4, and can close the water supplementing port of the buffer tank 4 when the liquid level in the buffer tank 4 reaches a preset height.

[0068] When it is necessary to supplement the temperature adjusting medium in the buffer tank 4, the first on-off valve 1001 can be opened, so that the temperature adjusting medium enters the water supplementing port of the buffer tank 4 through the water inlet pipeline 10, so that the liquid level in the buffer tank 4 gradually rises, and when the liquid level reaches the preset height, the buoyancy valve 11 closes the water supplementing port of the buffer tank 4, so that the temperature adjusting medium in the water inlet pipeline 10 cannot enter any more, thereby effectively preventing the problem of excessively high liquid level caused by excessive water supplementing.

[0069] Through the above arrangement, the supplement of the temperature adjusting medium can be conveniently and quickly completed, and the situation of excessive water supplementing is avoided, thereby improving the maintenance efficiency and reducing the labor intensity of the workers.

[0070] In some embodiments, as shown in Figure 1 , a first one-way valve 203 and a second on-off valve 204 are connected in series on the third branch of the supply pipeline 2, for maintaining stable pressure.

[0071] By opening or closing the second on-off valve 204, the one-way flow characteristic of the first one-way valve 203 can be utilized to maintain stable pressure in the heat exchanger 1, thereby further improving the stability and reliability of the system.

[0073] By arranging the second one-way valve 602, it is ensured that the temperature adjusting medium can only flow in one direction in the circulating loop, thereby preventing system disorder caused by reverse flow and improving the operation stability.

[0074] By arranging the third on-off valve 603, the third on-off valve 603 can be closed when the buffer tank 4 needs to be maintained, thereby blocking the temperature adjusting medium in the output pipeline 6 from being delivered to the buffer tank 4, so as to facilitate the maintenance of the buffer tank 4.

[0075] By arranging the first filter valve 604, impurities in the temperature adjusting medium can be filtered during the circulation of the temperature adjusting medium, thereby protecting the system from being blocked and worn.

[0076] In some embodiments, further comprising: an air inlet pipeline 12 and an air outlet pipeline 13; wherein the air inlet pipeline 12 is connected in series with the fourth on-off valve 1201 and the third one-way valve 1202, and one end of the air inlet pipeline 12 is connected in communication with the air inlet of the buffer tank 4; one end of the air outlet pipeline 13 is connected in communication with the air outlet of the buffer tank 4.

[0077] It should be noted that nitrogen can be used as a compression medium, which is compressed when the pipeline pressure rises to absorb excess pressure, and expanded when the pipeline pressure decreases to make up for insufficient pressure, thereby maintaining the stability of the system pressure.

[0078] By opening the fourth on-off valve 1201 on the air inlet pipeline 12, nitrogen and other inert gases can be allowed to enter the buffer tank 4 through the air inlet pipeline 12 to maintain the stability of the system pressure and provide safety protection, wherein the third one-way valve 1202 is used to realize one-way flow to ensure system stability. One end of the air outlet pipeline 13 is connected in communication with the air outlet of the buffer tank 4, which is used to discharge the gas in the tank when needed.

[0080] When the system is abnormal or needs to be shut down for maintenance, the industrial steam supply can be cut off by closing the third shut-off valve 205 to prevent the system from overheating or being damaged due to continued inflow of steam. The second filter valve 206 can filter out impurities in the steam to protect system components from damage and improve the stability and reliability of the system.

[0081] The third filter valve 207 can filter out impurities in the cooling water to protect system components from damage and improve the stability and reliability of the system. The fifth on-off valve 208 can cut off the cooling water supply to prevent system damage due to continued inflow of cooling water.

[0082] Through the above arrangement, the supply of industrial steam and cooling water can be cut off when the system is abnormal or needs to be shut down for maintenance, thereby preventing system damage due to continued inflow and playing a fault isolation role to prevent fault propagation and protect the safe operation of the entire system. In addition, impurities can be filtered out to protect system components from damage and improve the stability and reliability of the system.

[0083] In some embodiments, a temperature transmitter 605 is installed on the output pipeline 6, and the temperature transmitter 605 is located between the communication point of the heat exchanger 1 and the temperature adjustment pipeline 7.

[0084] Through the above arrangement, the temperature of the temperature adjustment medium flowing out of the heat exchanger 1 can be monitored in real time, and the system can adjust the power of the circulating pump 501 accordingly to adjust the flow rate of the temperature adjustment medium, so as to keep the temperature adjustment medium within the ideal temperature range.

[0085] In some embodiments, a sixth on-off valve 702 is connected in series on each branch of the temperature regulating pipeline 7, which plays a fault isolation role, when the reactor at the back end needs to be maintained, the temperature regulating medium supply can be cut off to prevent the system from being damaged due to continuous supply.
