Description

Technical Field

[0001] The invention relates to the technical field of heating water supply, and in particular to a water supply device for a heating station. Background Art

[0002] A heating station is a facility that provides centralized heating services for buildings or regions. It delivers heat energy to each user through a pipeline system to create a warm and comfortable indoor environment. The heating station not only effectively utilizes energy, but also improves heating efficiency through centralized management. It is an important part of the heating system.

[0003] In the pipelines of heating stations in factory areas and other areas, a steam line is generally led from the low-pressure heating pipeline to enter the heating station to heat desalted water to provide heating for the factory area and dormitory area. The heating station is generally composed of two circulating water pumps, two make-up water pumps, two heat exchangers and auxiliary pipelines. A safety valve is installed on the water side of the heating station with an operating pressure of 0.86Mpa, and two safety valves are installed on the steam side of the heating station with an operating pressure of 0.86Mpa. During operation, the outlet pressure and temperature can be adjusted according to the weather temperature conditions to ensure heating needs. Because the heating station make-up water directly comes from the desalted water, the degassing of each radiator and the leakage of the pipeline during daily operation will directly cause the waste of desalted water. Therefore, the present invention proposes a water supply device for a heating station to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the present invention proposes a water supply device for a heating station, which uses the water in the boiler fixed-discharge recovery pool to supplement the water used in the heating station, which can greatly save the amount of stale brine and achieve energy saving.

[0005] To achieve the purpose of the present invention, the present invention is implemented through the following technical solutions: a heating station water supply device, including a pipeline system and a control system, the pipeline system includes a boiler fixed-discharge recovery water pump, a desalted water replenishment source, and a water replenishment pipeline, the input end of the water replenishment pipeline is connected to the desalted water replenishment heating station, and the output end of the water replenishment pipeline is connected to the heating station circulation pump, the output end of the heating station circulation pump is respectively connected to the dormitory area and the production area, the output end of the boiler fixed-discharge recovery water pump is connected to an additional pipeline, and the output end of the additional pipeline is connected to the water replenishment pipeline, and the input end of the boiler fixed-discharge recovery water pump is connected to the boiler fixed-discharge recovery water tank;

[0006] The control system is used to collect pressure and flow data of the water supply pipeline, and has built-in control logic algorithms and parameter thresholds. The boiler fixed-discharge recovery water pump is turned on first. When the internal pressure and flow data of the water supply pipeline do not meet the parameter threshold, the water supply amount is calculated by the control logic algorithm. The control system controls the opening of the desalted water supply source to make up for the difference based on the calculation results. The control system has a built-in error compensation model for collecting actual water output changes in the dormitory area and the production area, and comparing the water supply amounts of the boiler fixed-discharge recovery water pump and the desalted water supply source, so as to calculate the error value and compensate the control values ​​of the boiler fixed-discharge recovery water pump and the desalted water supply source.

[0007] A further improvement is that a pressure sensor and a flow sensor are provided on the water supply pipeline, and the pressure sensor and the flow sensor are used to collect water pressure and water flow data inside the water supply pipeline respectively.

[0008] A further improvement is that the output ends of the boiler fixed-discharge recovery water pump and the desalted water replenishment source are both provided with intelligent control valves, and the intelligent control valve of the boiler fixed-discharge recovery water pump is kept in a normally open state.

[0009] A further improvement is that the boiler fixed-discharge recovery water pool is used to recover the boiler's soot blowing and fixed-discharge drainage, and a water purification device is provided at the output end of the boiler fixed-discharge recovery water pool, and the water purification device is used to purify the water and control its water quality to meet the water quality requirements of the heating station.

[0013] Set the real-time pressure of the water supply pipeline: Preal, the real-time flow: Qreal, the target pressure threshold: Ptarget, and the target flow threshold: Qtarget;

[0014] Determine whether the current pressure Preal is lower than the target pressure threshold Ptarge, and determine whether the current flow rate Qreal is lower than the target flow rate threshold Qtarget;

[0015] When any of the conditions is not met, the water replenishment calculation is performed:

[0016] Calculate the pressure difference: ΔP = Ptarget-Preal;

[0017] Calculate the flow difference: ΔQ = Qtarget-Qreal;

[0018] Assuming that the water replenishment amount is linearly related to the pressure difference and the flow difference, a proportional coefficient kp and kq are set to calculate the water replenishment amount:

[0019] Vsupplement=kp·ΔP+kq·ΔQ,

[0020] Vsupplement=k·(ΔP+α·ΔQ),

[0021] Among them, α is the weight factor between flow and pressure;

[0022] Based on the calculated replenishment volume Vsupplement, a signal is sent to the intelligent control valve of the demineralized water replenishment source to adjust its output to match the required replenishment volume.

[0023] Further improvement is that: the parameter compensation module has a built-in error compensation model, which is used to collect the actual water output change value of the dormitory area and the production area, and compare the water replenishment volume of the boiler fixed discharge recovery pump and the desalted water replenishment source to calculate the error value, which specifically includes the following steps:

[0024] Calculate the total water demand of dormitory area + production area at time t:

[0025] Wtotal_demand(t)=Wout_dormitory(t)+Wout_production(t)

[0026] Calculate the difference between the total replenishment amount and the total water demand, that is, the error value:

[0027] ΔW(t)=Wtotal_demand(t)-(Wrecycled(t)+Wdemin(t))

[0028] Among them, Wout_dormitory(t): the actual water output of the dormitory area at time t; Wout_production(t): the actual water output of the production area at time t; Wrecycled(t): the water replenishment volume of the boiler fixed discharge recovery pump at time t; Wdemin(t): the water replenishment volume of the desalted water replenishment source at time t.

[0038] A further improvement is that the control system has a built-in log module, and the log module interacts with the manager's mobile terminal to provide the manager with all records and timestamps of the pipeline system regulation.

[0039] The beneficial effects of the present invention are:

[0040] 1. The present invention adds a pipe to the water supply pipe at the outlet of the boiler fixed-discharge recovery water pump. The outlet of the boiler fixed-discharge recovery water pump is kept in a normally open state. When the boiler fixed-discharge recovery water pump is in operation, the water supply to the heating station can be normally guaranteed without opening the desalted water supply source for water supply. When the boiler fixed-discharge recovery water pump stops operating, the desalted water supply source can be adaptively opened for water supply. Therefore, the water in the boiler fixed-discharge recovery water pool is used to supplement the water used in the heating station, which can greatly save the amount of stale brine and achieve the purpose of energy saving.

[0041] 2. The present invention collects the pressure and flow data of the water supply pipeline in real time, and sets the boiler fixed-discharge recovery pump to be opened first. When the internal pressure and flow data of the water supply pipeline do not meet the set parameter threshold, the water supply amount is calculated through the control logic algorithm, and the desalted water supply source is controlled to open to make up for the difference, thereby maximizing the utilization rate of the desalted water and saving more energy.

[0042] 3. The present invention is based on an error compensation model. The error value is calculated according to the actual water output change value of the dormitory area and the production area, and the water replenishment amount of the boiler fixed-discharge recovery water pump and the desalted water replenishment source. Thus, the control value of the boiler fixed-discharge recovery water pump and the desalted water replenishment source is compensated according to the real-time proportion, so that the control amount of the replenishment amount is more in line with the actual replenishment amount, thereby reducing the system error.

[0044] Figure 2 It is a schematic diagram of the control system of the present invention. DETAILED DESCRIPTION

[0045] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0046] Embodiment 1

[0047] according to Figure 1 , 2 As shown, this embodiment proposes a heating station water supply device, including a pipeline system and a control system, wherein the pipeline system includes a boiler fixed-discharge recovery water pump, a desalted water replenishment source, and a replenishment pipe, wherein the input end of the replenishment pipe is connected to the desalted water replenishment heating station, and the output end of the replenishment pipe is connected to the heating station circulation pump, and the output end of the heating station circulation pump is respectively connected to the dormitory area and the production area, the output end of the boiler fixed-discharge recovery water pump is connected to an additional pipe, and the output end of the additional pipe is connected to the replenishment pipe, and the input end of the boiler fixed-discharge recovery water pump is connected to the boiler fixed-discharge recovery water tank;

[0048] The control system is used to collect pressure and flow data of the water supply pipeline, and has built-in control logic algorithms and parameter thresholds. The boiler fixed-discharge recovery water pump is turned on first. When the internal pressure and flow data of the water supply pipeline do not meet the parameter threshold, the water supply amount is calculated by the control logic algorithm. The control system controls the opening of the desalted water supply source to make up for the difference based on the calculation results. The control system has a built-in error compensation model for collecting actual water output changes in the dormitory area and the production area, and comparing the water supply amounts of the boiler fixed-discharge recovery water pump and the desalted water supply source, so as to calculate the error value and compensate the control values ​​of the boiler fixed-discharge recovery water pump and the desalted water supply source. When in use, an additional pipe is connected to the boiler water recovery pump outlet to the water make-up pipe, and the boiler water recovery pump outlet remains normally open. When the boiler water recovery pump is in operation, the water supply to the heating station can be guaranteed normally without opening the desalted water make-up source for water. When the boiler water recovery pump stops operating, the desalted water make-up source can be adaptively opened to make water. Therefore, using the water in the boiler water recovery pool to supplement the water used in the heating station can greatly save the use of stale brine and achieve the purpose of energy saving.

[0049] The water supply pipeline is provided with a pressure sensor and a flow sensor, and the pressure sensor and the flow sensor are used to collect water pressure and water flow data inside the water supply pipeline respectively. The output ends of the boiler fixed-discharge recovery water pump and the desalted water supply source are both provided with intelligent control valves, and the intelligent control valve of the boiler fixed-discharge recovery water pump is kept in a normally open state. The intelligent control valve is used to control the opening and closing and the opening degree of the fixed-discharge recovery water pump and the desalted water supply source, and the water volume is controlled by the opening degree.

[0050] The boiler fixed-discharge recovery pool is used to recover the soot blowing and fixed-discharge drainage of the boiler. A water purification device is arranged at the output end of the boiler fixed-discharge recovery pool, and the water purification device is used to purify the water and control its water quality to meet the water quality requirements of the heating station. The water purification device ensures that the water quality in the boiler fixed-discharge recovery pool meets the standards to avoid damage to the heating station and related pipelines.

[0051] The control system includes a data acquisition module, a human-computer interaction module, a calculation control module and a parameter compensation module. The data acquisition module is used to collect identification data of the pressure sensor and the flow sensor, and the data acquisition module is also used to collect the opening and closing status and opening degree of two groups of intelligent control valves.

[0052] The human-computer interaction module is built into the mobile terminal for the management personnel to perform manual operation. The human-computer interaction module is used for the management personnel to manually set the parameter thresholds of the water replenishment flow and pressure of the water replenishment pipeline, which is convenient for manual setting of data.

[0053] The calculation control module is used to calculate the water replenishment amount when the internal pressure and flow data of the water replenishment pipeline do not meet the parameter threshold, and the calculation result controls the desalted water replenishment source to start and make up for the difference, specifically including the following steps:

[0054] Set the real-time pressure of the water supply pipeline: Preal, the real-time flow: Qreal, the target pressure threshold: Ptarget, and the target flow threshold: Qtarget;

[0055] Determine whether the current pressure Preal is lower than the target pressure threshold Ptarge, and determine whether the current flow rate Qreal is lower than the target flow rate threshold Qtarget;

[0056] When any of the conditions is not met, the water replenishment calculation is performed:

[0057] Calculate the pressure difference: ΔP = Ptarget-Preal;

[0058] Calculate the flow difference: ΔQ = Qtarget-Qreal;

[0059] Assuming that the water replenishment amount is linearly related to the pressure difference and the flow difference, a proportional coefficient kp and kq are set to calculate the water replenishment amount:

[0060] Vsupplement=kp·ΔP+kq·ΔQ,

[0061] Vsupplement=k·(ΔP+α·ΔQ),

[0062] Among them, α is the weight factor between flow and pressure;

[0063] According to the calculated replenishment volume Vsupplement, a signal is sent to the intelligent control valve of the desalted water replenishment source to adjust its output to match the required replenishment volume. The pressure and flow data of the replenishment pipeline are collected in real time, and the boiler fixed discharge recovery pump is set to be opened first. When the internal pressure and flow data of the replenishment pipeline do not meet the set parameter threshold, the replenishment volume is calculated through the control logic algorithm, and the desalted water replenishment source is controlled to open to make up for the difference, thereby maximizing the utilization rate of the desalted water and saving more energy.

[0064] The parameter compensation module has a built-in error compensation model, which is used to collect the actual water output change values ​​of the dormitory area and the production area, and compare the water replenishment of the boiler fixed discharge recovery pump and the desalted water replenishment source to calculate the error value, which specifically includes the following steps:

[0065] Calculate the total water demand of dormitory area + production area at time t:

[0066] Wtotal_demand(t)=Wout_dormitory(t)+Wout_production(t)

[0067] Calculate the difference between the total replenishment amount and the total water demand, that is, the error value:

[0068] ΔW(t)=Wtotal_demand(t)-(Wrecycled(t)+Wdemin(t))

[0069] Among them, Wout_dormitory(t): the actual water output of the dormitory area at time t; Wout_production(t): the actual water output of the production area at time t; Wrecycled(t): the water replenishment volume of the boiler fixed discharge recovery pump at time t; Wdemin(t): the water replenishment volume of the desalted water replenishment source at time t.

[0070] Compensating the control value of the boiler fixed discharge recovery water pump and the desalted water replenishment source specifically includes the following steps:

[0071] According to the error value ΔW(t), the control values ​​of the boiler fixed discharge recovery water pump and the demineralized water replenishment source are adjusted, and the compensation value is calculated according to the real-time distribution ratio of the two water sources;

[0072] Set the allocation ratio: Set the boiler fixed discharge recovery pump and the demineralized water supply source to share the error compensation according to the ratio of A:B

[0073] ΔWrecycled(t)=A÷(A+B)·ΔW(t)

[0074] ΔWdemin(t)=B÷(A+B)·ΔW(t)

[0075] Adjust the control value:

[0076] Wrecycled_adjusted(t+1)=Wrecycled(t)+ΔWrecycled(t)

[0077] Wdemin_adjusted(t+1)=Wdemin(t)+ΔWdemin(t)

[0078] Wrecycled_adjusted(t+1) and Wdemin_adjusted(t+1) are sent as new control instructions to the intelligent control valves of the boiler fixed discharge recovery water pump and the desalted water replenishment source. Based on the error compensation model, the error value is calculated according to the actual water output change value of the dormitory area and the production area, and the water replenishment amount of the boiler fixed discharge recovery water pump and the desalted water replenishment source is compared. Therefore, the control value of the boiler fixed discharge recovery water pump and the desalted water replenishment source is compensated according to the real-time ratio, so that the control amount of the replenishment amount is more in line with the actual replenishment amount, reducing the system error.

[0079] The error compensation model has a built-in deep learning algorithm, which is composed of a multi-layer neural network. It automatically learns the complex relationship between the actual water output of the dormitory area and production area and the water replenishment of the boiler recovery pump and the desalted water replenishment source. It accurately calculates the water replenishment error value and dynamically adjusts the control value accordingly to achieve efficient and accurate heating system water replenishment control.

[0080] Embodiment 2

[0081] according to Figure 1 , 2As shown, this embodiment proposes a heating station water supply device, including a pipeline system and a control system, wherein the pipeline system includes a boiler fixed-discharge recovery water pump, a desalted water replenishment source, and a replenishment pipe, wherein the input end of the replenishment pipe is connected to the desalted water replenishment heating station, and the output end of the replenishment pipe is connected to the heating station circulation pump, and the output end of the heating station circulation pump is respectively connected to the dormitory area and the production area, the output end of the boiler fixed-discharge recovery water pump is connected to an additional pipe, and the output end of the additional pipe is connected to the replenishment pipe, and the input end of the boiler fixed-discharge recovery water pump is connected to the boiler fixed-discharge recovery water tank;

[0082] The control system is used to collect pressure and flow data of the water supply pipeline, and has built-in control logic algorithms and parameter thresholds. The boiler fixed-discharge recovery water pump is turned on first. When the internal pressure and flow data of the water supply pipeline do not meet the parameter threshold, the water supply amount is calculated by the control logic algorithm. The control system controls the opening of the desalted water supply source to make up for the difference based on the calculation results. The control system has a built-in error compensation model for collecting actual water output changes in the dormitory area and the production area, and comparing the water supply amounts of the boiler fixed-discharge recovery water pump and the desalted water supply source, so as to calculate the error value and compensate the control values ​​of the boiler fixed-discharge recovery water pump and the desalted water supply source. When in use, an additional pipe is connected to the boiler water recovery pump outlet to the water make-up pipe, and the boiler water recovery pump outlet remains normally open. When the boiler water recovery pump is in operation, the water supply to the heating station can be guaranteed normally without opening the desalted water make-up source for water. When the boiler water recovery pump stops operating, the desalted water make-up source can be adaptively opened to make water. Therefore, using the water in the boiler water recovery pool to supplement the water used in the heating station can greatly save the use of stale brine and achieve the purpose of energy saving.

[0083] The control system has a built-in log module, and the log module interacts with the manager's mobile terminal to provide the manager with all the records and timestamps of the pipeline system control, making it convenient for the manager to query and retrieve data to achieve the purpose of troubleshooting.

[0084] The water supply device of the heating station connects an additional pipeline to the water supply pipeline at the outlet of the boiler fixed discharge recovery water pump, and the outlet of the boiler fixed discharge recovery water pump remains in a normally open state. When the boiler fixed discharge recovery water pump is in operation, the water supply of the heating station can be guaranteed normally, and there is no need to open the desalted water supply source for water supply. When the boiler fixed discharge recovery water pump is out of operation, the desalted water supply source can be adaptively opened for water supply. Thus, the water in the boiler fixed discharge recovery water pool is used to supplement the water used in the heating station, which can greatly save the amount of stale salt water and achieve the purpose of energy saving. At the same time, the present invention collects the pressure and flow data of the water supply pipeline in real time, and sets the boiler fixed discharge recovery water pump to be opened first. When the internal pressure and flow data of the water supply pipeline do not meet the set parameter threshold, the water supply amount is calculated through the control logic algorithm, and the desalted water supply source is controlled to open to make up for the difference, thereby maximizing the utilization rate of the desalted water and saving more energy. In addition, the present invention is based on an error compensation model, and calculates the error value according to the actual water output change value of the dormitory area and the production area, and compares it with the water replenishment amount of the boiler fixed-discharge recovery water pump and the desalted water replenishment source. Thus, the control value of the boiler fixed-discharge recovery water pump and the desalted water replenishment source is compensated according to the real-time proportion, so that the control amount of the replenishment amount is more in line with the actual replenishment amount, thereby reducing the system error.
