[0002] With the decreasing fossil energy, the utilization and development of non-fossil energy such as photovoltaic and wind power has gradually accelerated, resulting in serious abandonment of photovoltaic and wind power. In order to absorb the abandonment of photovoltaic and wind power, researchers have studied a variety of treatment plans. Among them, using the electricity generated by the abandonment of photovoltaic and wind power to heat large electric boilers to produce hot water to provide heating for users is a good solution for absorbing wind and solar power.

[0003] Large electric boilers generally use electrode hot water boilers. Electrode hot water boilers have "cold water" and "hot water" discharged from the bottom of the boiler and returned to the water pipe seat. The hot water is cooled by heat exchange through the circulating water pump, circulating pipe, plate heat exchanger, electric three-way first regulating valve, etc., and then enters the boiler return water, and the cycle repeats. When using electrode boilers for heating, the heat exchange regulation and balancing technology of electrode hot water boilers is required to ensure the efficiency, safety and stability of boiler operation.

[0059] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0060] The following describes the boiler heat exchange regulation and balancing system and method, device, and electronic equipment according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0061] Figure 1 A schematic structural diagram of a boiler heat exchange regulation and balancing system provided in an embodiment of the present disclosure.

[0062] like Figure 1 As shown, the boiler heat exchange regulation and balance system includes: an electrode boiler 11, a plate heat exchanger 12, a primary loop 13 and a secondary loop 14, wherein the primary loop 13 includes a circulation pump 131 and a first regulating valve 132, and the secondary loop 14 includes a second regulating valve 141.

[0063] The electrode boiler 11 is used to generate a first output medium and transmit the first medium to the plate heat exchanger 12 through the primary circuit;

[0064] The plate heat exchanger 12 is used to perform temperature adjustment on the first output medium to obtain a second output medium, and transmit the first return medium to the electrode boiler 11 through the primary loop 13; wherein the first return medium is the medium obtained after the plate heat exchanger 12 performs heat exchange on the first output medium;

[0065] The circulation pump 131 and the first regulating valve 132 are used to adjust the temperature of the first output medium in the primary loop 13 through joint control according to the current working condition of the demand end, so as to obtain the output medium with the first temperature; wherein the demand end is the target to be heated that needs to be heated;

[0066] The second regulating valve 141 is used to adjust the flow rate of the second reflux medium transmitted from the demand end to the plate heat exchanger 12 through the secondary loop 14 according to the current working conditions to obtain a reflux medium of a first flow rate; wherein the second reflux medium is the medium generated after the second output medium performs heat supply processing on the demand end;

[0067] The plate heat exchanger 12 is also used to perform temperature adjustment processing on the second output medium according to the output medium at the first temperature and the return medium at the first flow rate to obtain the output medium at the second temperature, wherein the output medium at the second temperature is used to supply heat to the demand end.

[0068] The boiler heat exchange regulation and balancing system responds to the current operating conditions on the demand side through the cooperation of the plate heat exchanger, the second regulating valve, the circulating pump and the first regulating valve. It can quickly adjust the temperature when the operating conditions on the demand side change, adapt to the complex operating conditions on the demand side, and respond to changes in demand in a timely manner.

[0069] In an implementable manner of the embodiment of the present disclosure, the primary circuit 13 further includes: a first input port 133, a first output port 134,

[0070] The first input port 133 is used to transmit the first output medium generated by the electrode boiler 11 to the plate heat exchanger 12;

[0071] The first output port 134 is used to transfer the first return medium in the plate heat exchanger 12 to the electrode boiler 11 .

[0072] In one possible implementation of the embodiment of the present disclosure, the secondary circuit 14 further includes: a second output port 142, a second input port 143,

[0073] The second output port 142 is used to transfer the second output medium to the demand end to provide heat to the demand end;

[0074] The second input port 143 is used to transmit the second return medium to the plate heat exchanger 12 .

[0075] In the boiler heat exchange regulation and balancing system, the electrode boiler 11 is connected to the plate heat exchanger 12 through the primary loop 13, and the plate heat exchanger 12 is connected to the demand end through the secondary loop 14. The lower water outlet pipe seat of the electrode boiler 11 is connected to the primary side input end (the first input port 133 of the primary loop 13) of the plate heat exchanger 12 through the circulating pump 131, and the hot water generated by the electrode boiler 11, that is, the first output medium, is extracted through the circulating pump 131 and input to the primary side input end (the first input port 133) of the plate heat exchanger 12; the primary side output end (the first output port 134) of the plate heat exchanger 12 is connected to the return water pipe seat of the electrode boiler 11 through the first regulating valve 132, and the hot water generated by the electrode boiler 11, that is, the first output medium, is extracted through the circulating pump 131 and input to the primary side input end (the first input port 133) of the plate heat exchanger 12. The water exchanged with heat by the plate heat exchanger 12 enters the inner cylinder of the electrode boiler 11; a certain space is reserved at the top of the electrode boiler 11, and a high-voltage electrode is arranged in the electrode boiler 11. The water in the inner cylinder of the electrode boiler 11 is heated by the high-voltage electrode and returns to the outlet pipe seat at the bottom of the electrode boiler 11 through the downpipe; the other side of the plate heat exchanger 12 is respectively connected to the cold side water inlet pipe (the second input port 143) and the outlet pipe (the second output port 142), and heat is exchanged with the primary circuit 13 side. Since the boiler heat exchange regulation and balance system has a large heat exchange capacity, a small temperature difference, and a large circulating water flow rate, in order to ensure the stability of the heat exchange balance, a regulating device, a second regulating valve 141, is added to the cold side water inlet pipe (the second input port 143) and the outlet pipe (the second output port 142) of the plate heat exchanger 12.

[0076] The main process of the boiler heat exchange regulation and balance system for heat exchange regulation and balance is to increase the temperature of the full-flow low-temperature return water (second reflux medium) at the demand end and the temperature of the large-flow high-temperature outlet water (first output medium) from the original small temperature difference to the large temperature difference formed by the temperature of the low-temperature return water (first flow reflux medium) with reduced flow through the second regulating valve 141 and the high-temperature hot water (first temperature output medium) with reduced flow coming out of the plate heat exchanger 12. The flow of the second reflux medium is partially reduced by the second regulating valve 141, and the remaining flow enters the plate heat exchanger 12 for heat exchange absorption. The heat increases to a higher temperature than the second output medium and reaches the outlet of the plate heat exchanger 12, and is mixed with the partial flow of the second reflux medium coming out of the second regulating valve 141 to reach the rated temperature of the demand end.

[0077] In one possible implementation of the embodiment of the present disclosure, the second regulating valve 141 is further used to perform valve opening adjustment processing according to the current working condition to obtain a target valve opening, and to perform flow adjustment processing on the second reflux medium according to the target valve opening to obtain the reflux medium of the first flow rate;

[0078] The target valve opening is used to make the flow pressure loss of the second output port and the second input port meet the preset pressure loss condition;

[0079] The target valve opening is also used to make the first temperature difference and the second temperature difference meet the preset temperature difference condition, the first temperature difference is the temperature difference between the output medium at the second temperature and the second return medium, and the second temperature difference is the temperature difference between the output medium at the first temperature and the first return medium.

[0080] In one implementable manner of the embodiment of the present disclosure, the plate heat exchanger 12 is further used to mix the output medium at the first temperature, the return medium at the first flow rate, and the second output medium to obtain the output medium at the second temperature.

[0081] In the boiler heat exchange regulation and balance system, the energy on the primary side of the plate heat exchanger 12 (i.e., the energy of the primary loop 13) is supplemented to the secondary side (secondary loop 14) of the plate heat exchanger 12; the heat absorbed by the secondary side of the plate heat exchanger 12 (the heat absorbed by the secondary loop 14) and the energy released by the primary side of the plate heat exchanger 12 (the energy released by the primary loop) must be the same. In order to determine the opening of the second regulating valve 141, i.e., the target opening, it is first necessary to control the inlet and outlet temperature difference of the primary side of the plate heat exchanger 12 (the temperature difference between the first input port 133 and the first output port 134) to be greater than or equal to the temperature difference of the full flow low-temperature return water side of the secondary side and the full flow high-temperature outlet water side (the temperature difference between the second input port 143 and the second output port 142). After that, the second regulating valve 141 is normally open, the water pumps on both sides of the plate heat exchanger 12 are turned on, and the bypass flow is reduced (the opening of the second regulating valve 141 is reduced). When the temperature difference (first temperature difference) on the primary side of the plate heat exchanger 12 is close to the temperature difference (second temperature difference) between the temperature of the full-flow low-temperature return water side and the temperature of the full-flow high-temperature outlet water side of the secondary side of the plate heat exchanger 12; and at the same time, the pressure loss of the inlet and outlet of the secondary side of the plate heat exchanger 12 is within the acceptable range (the flow pressure loss of the second output port 142 and the second input port 143 meets the preset pressure loss condition), the target valve opening can be obtained at this time.

[0082] Among them, the preset pressure loss condition is a custom set condition, for example: the pressure loss must be less than or equal to 50Pa, the pressure loss must not exceed 10%*H (H is the head of the pump), etc., and the preset temperature difference condition is a custom set condition, for example: the difference between the first temperature difference and the second temperature difference is less than 1°C, the first temperature difference is the same as the second temperature difference, etc. Specifically, with regard to the preset pressure loss condition and the preset temperature difference condition, the embodiments of the present disclosure do not impose any restrictions.

[0083] In one possible implementation of the embodiment of the present disclosure, the electrode boiler 12 is further used to obtain load change information when the load at the power input end changes;

[0084] The circulation pump 131 and the first regulating valve 132 are further used to perform joint control and regulation processing according to the load change information to adjust the temperature of the first output medium transmitted in the primary loop to obtain an output medium with a third temperature.

[0085] The second regulating valve 141 is further used to perform valve opening adjustment processing according to the load change information to obtain a second valve opening, and to perform flow adjustment processing on the second reflux medium according to the second valve opening to obtain the second flow of reflux medium;

[0086] The plate heat exchanger 12 is further used to perform temperature adjustment processing according to the return medium of the second flow rate and the output medium of the three temperatures, so that the temperature of the output medium of the second temperature remains unchanged.

[0087] Among them, when the secondary side of the plate heat exchanger 12 responds to changes in operating conditions (when the secondary loop 14 responds to changes in operating conditions on the demand side), in order to ensure the heat exchange balance on both sides of the plate heat exchanger 12, the heat production of the electrode boiler 11 meets the demand, and the circulation pump 131 and the first regulating valve 132 are jointly controlled and adjusted, so that the heat generated by the electrode boiler 11 and the temperature difference between the inlet and outlet of the primary side of the plate heat exchanger 12 (the first temperature difference) meet the temperature difference between the full-flow low-temperature return water side and the full-flow high-temperature outlet water side of the secondary side of the plate heat exchanger 12 (the second temperature difference), thereby realizing the stable operation of the heat exchange regulation and balance system of the electrode boiler 11.

[0088] While satisfying the response operating conditions of the secondary side of the plate heat exchanger 12, the electrode boiler 11 also needs to satisfy the change requirements of the power input end of the electrode boiler 11 itself. When the load at the power input end changes within the allowable adjustment range, the boiler heat exchange regulation and balance system including the electrode boiler 11, the circulating pump 131, the plate heat exchanger 12 and the first regulating valve 132 is jointly controlled and adjusted through the circulating pump 131 and the first regulating valve 132, which not only satisfies the operating condition changes on the secondary side of the plate heat exchanger 12, but also satisfies the load changes at the power input end of the electrode boiler 11, thereby realizing the stable operation of the heat exchange regulation and balance system of the electrode boiler 11.

[0089] The boiler heat exchange regulation and balancing system described in the present disclosure is not limited in the types of hardware. Specifically, for example, the electrode boiler 11 can be a high-voltage electrode hot water boiler, the first regulating valve 132 can be an electric three-way regulating valve, the second regulating valve 141 can be a two-way regulating valve, etc. Specifically, the types of hardware in the boiler heat exchange regulation and balancing system can be selected according to actual conditions, and the embodiments of the present disclosure are not limited.

[0090] Figure 2 The following is a flow chart of a boiler heat exchange balance adjustment method provided by an embodiment of the present disclosure. Figure 2As shown, the method comprises the following steps:

[0091] Step 201, obtaining the current working condition of the demand side, and performing temperature adjustment processing on the first output medium according to the current working condition to obtain an output medium with a first temperature; wherein the first output medium is the initial heating medium generated by the heating equipment.

[0092] In the disclosed embodiment, obtaining the current working condition of the demand side means that the state of the demand side needs to be monitored in real time or regularly. The demand side usually refers to a place where heat is needed, such as a room in a building, a production line in a factory, etc. The current working condition may include but is not limited to parameters such as temperature, humidity, flow, and pressure. This parameter is key information that determines how the heating system adjusts the output.

[0093] When the temperature of the first output medium is adjusted, the adjustment is mainly performed through the circuit for conveying the first output medium. The circulation pump and the electric regulating valve included in the circuit for conveying the first output medium can jointly control and adjust the flow of the first output medium to achieve the purpose of temperature regulation.

[0094] Step 202, flow regulation processing is performed on the second reflux medium according to the current operating condition to obtain a reflux medium of the first flow rate; the second reflux medium is a medium generated after heat treatment is performed on the demand end of the historical operating condition, and the demand end of the historical operating condition is the demand end in the operating condition state at the previous adjacent moment of the current operating condition.

[0095] In the embodiment of the present disclosure, when the flow rate of the second reflux medium is regulated, the system will adjust the flow rate of the reflux medium according to the current working conditions of the demand side (such as the current temperature, humidity, etc.). The flow rate regulation process requires the use of a valve to increase or decrease the flow rate of the second reflux medium, for example: a regulating valve on the circuit for conveying the second reflux medium is used to reduce part of the flow rate, a part of the flow rate, i.e., the reflux medium of the first flow rate, is used for heat exchange absorption, and another part of the flow rate is used to mix the medium after heat exchange absorption to reach the rated temperature of the demand side.

[0096] The first flow rate of the return medium is the flow rate of the return medium after adjustment to a specific level. The first flow rate is set to meet the heating demand under the current working condition, with the purpose of optimizing the performance and efficiency of the heating system. The historical working condition refers to the state of the demand side at the moment immediately before the current working condition. By comparing the current working condition with the historical working condition, the system can evaluate the change in the heat demand on the demand side and adjust the flow rate of the return medium accordingly.

[0097] Step 203, temperature-regulating the second output medium according to the reflux medium of the first flow rate and the output medium of the first temperature to obtain the output medium of the second temperature, wherein the output medium of the second temperature is used to heat the demand end, and the second output medium is a medium for heating the demand end under historical working conditions.

[0098] In the embodiment of the present disclosure, part of the flow rate is reduced by a regulating valve on the circuit for conveying the second reflux medium, a part of the flow rate, i.e., the reflux medium of the first flow rate, is subjected to heat exchange absorption treatment with the output medium of the first temperature, and another part of the flow rate is used to mix the medium after heat exchange absorption to obtain the output medium of the second temperature.

[0099] The output medium of the second temperature is the temperature of the output medium after the adjustment process reaches a new set level. The second temperature is determined according to the current working conditions and the flow rate of the return medium, with the purpose of meeting the heating demand of the demand side.

[0100] By monitoring and adjusting the flow rate of the return medium and the temperature of the output medium, the heat supply to the demand side is optimized. The system adjusts the temperature of the heating medium according to actual demand, thereby improving energy efficiency and ensuring a stable and appropriate heat supply to the demand side.
