Fig. 3 is a schematic flowchart of an energy recovery scheduling method according to an embodiment of the present disclosure. As shown in fig. 3, the method includes:
s301, monitoring and acquiring the running state data of the steam recovery scheduling system in real time.
The system is characterized in that an internet of things collecting device is installed on a pipeline for producing and transporting industrial steam, the internet of things collecting device can be a steam flowmeter, a pressure sensor, a temperature sensor, an intelligent valve instrument and the like, is used for monitoring the running state of the industrial steam in a pipe network, and obtains real-time monitoring data in a wired or wireless mode. Monitored data includes, but is not limited to: steam pressure, steam temperature, steam flow, boiler load factor, valve opening. As an example, the steam pressure may be collected by a pressure sensor installed in the steam pipe to obtain steam pressure data.
And S302, performing data processing on the running state data, and determining output steam parameters.
The operation state data is cleaned, converted and combined, the combined data is summarized, the steam pressure, the steam flow, the steam temperature, the load of the boiler and the opening degree of a valve can be summarized according to the time dimension and the dimension of a service scene, the data can also be summarized from other dimensions, and the method is not limited specifically here. And extracting identification information of the summarized data, and storing the summarized data to a cloud server to obtain output steam parameters at least comprising real-time steam pressure, real-time steam temperature and real-time steam flow.
And S303, setting a target steam parameter according to the production process requirement, and judging whether the supply and demand of the industrial steam are balanced or not based on the output steam parameter and the target steam parameter.
Setting an upper limit value and a lower limit value of a required target steam parameter according to production process requirements, wherein the lower limit value can float within a fixed numerical range, the floating proportion is 5% -10%, and the target steam parameter comprises a target steam temperature, a target steam pressure and a target steam flow so as to meet the energy requirements of various production equipment in an energy consumption unit.
And performing supply and demand analysis based on the output steam parameters and the target steam parameters, wherein the judgment basis is to compare the output steam parameters in the pipe network with the upper and lower limit values of the target steam parameters, specifically, comparing the supply and demand states of the real-time steam pressure, the real-time steam temperature, the target steam flow and the target steam pressure in sequence, and determining whether the supply and demand are balanced.
For example, if the lower limit value of the target steam temperature is 100 ℃, the operation state data of the industrial steam is obtained in real time, the operation state data is subjected to summary analysis, the real-time industrial steam temperature is calculated to be 90 ℃, and the real-time steam temperature in the current state is judged to be lower than the target steam temperature by 100 ℃, so that the supply and demand state at the moment can be determined to be in supply and demand imbalance. Therefore, the real-time steam temperature needs to be updated to meet the demand of energy consumption units on industrial steam.
And if the supply and demand are balanced, continuously monitoring the running state data of the steam recovery scheduling system, analyzing the current supply and demand state according to the preset time frequency, and updating the current target steam parameter when the calculated output steam parameter is not within the range of the upper limit value and the lower limit value of the target steam parameter.
S304, if the supply and demand are unbalanced, the steam recovery dispatching system generates a control instruction corresponding to the equipment and issues the control instruction.
And if the supply and demand are unbalanced, generating a corresponding control instruction based on the supply and demand state of the industrial steam at the current moment, and issuing the control instruction to the equipment controller.
Specifically, based on the unbalanced state, steam pressure, steam temperature and steam flow are adjusted, and a control instruction is issued to a gas steam boiler or an intelligent valve to implement regulation, wherein the intelligent valve is used for controlling steam supply of a downstream energy consumption unit and is installed in a downstream pipe network. It should be noted that adjusting the boiler load rate or controlling the opening of the intelligent valve may be performed simultaneously, or one of them may be selected to be adjusted and controlled, the preset step length for adjusting the boiler load rate may be 10%, 15%, etc., and the preset step length for adjusting the valve opening may be 5%, 10%, etc., where no specific limitation is made, and the determination is performed according to the actual needs of the user. Of course, the industrial steam can be controlled by regulating other energy devices.
As an example, when the real-time steam pressure is higher than the upper limit value in the target steam pressure, it is judged that the supply and demand state is unbalanced at this time, and the supplied industrial steam is greater than the demand of the energy consumption unit. And starting regulation and control of the control equipment to ensure supply and demand balance of the industrial steam. If the gas-steam boiler is in the starting state at this time, the load rate of the boiler can be selectively reduced. For example, by reducing the fuel input and the oxygen content in the flue gas, so that the load factor of the boiler is reduced. When the steam supply quantity of the supply side is sufficient, the gas-fired steam boiler is not started at the moment, and the real-time steam delivery pressure can be reduced by adjusting the opening degree of a valve in a pipe network.
When the real-time steam flow is larger than the upper limit value of the target steam flow, the steam flow entering can be reduced by adjusting the valve opening in the pipe network or the valve opening of the energy utilization side so as to achieve the required value of the target steam flow; when the real-time steam temperature is higher than the upper limit value of the target steam temperature, if the gas-fired steam boiler is in the running state at the moment, the load factor of the gas-fired steam boiler can be reduced, and if the gas-fired steam boiler is not started at the moment, the real-time steam pressure can be reduced by adjusting the opening degree of a valve at the downstream energy utilization side, so that the real-time steam temperature can be adjusted.
And obtaining a lower limit value of the output steam parameter which is less than or equal to the target steam parameter through supply and demand analysis, and judging that the supply and demand state is unbalanced at the moment and the industrial steam supplied by an energy supply unit is less than the demand of an energy consumption unit. The main control terminal determines whether to start the gas steam boiler for supplementary supply according to actual needs.
Specifically, if the supply of the industrial steam flow rate on the energy supply side is insufficient, the gas-fired steam boiler is started to perform supplementary supply, and the steam flow rate of the industrial steam is increased by increasing the fuel intake and increasing the oxygen content in the flue gas. If the supply of the industrial steam on the energy supply side is sufficient, the gas steam boiler does not need to be started for supplying, the opening degree of a valve on the energy utilization side can be selectively increased, the flow rate of the industrial steam is increased, and the conveying amount of the industrial steam can meet the requirement of an energy utilization unit.
If the supply of the steam temperature and the steam pressure cannot meet the requirement of the energy consumption side, the steam temperature and the steam pressure are increased by increasing the load rate of the gas boiler or increasing the opening degree of a valve so as to meet the requirement of the energy consumption side on the industrial steam.
Furthermore, after the control instruction is issued, the controlled device responds to the control instruction and controls the device to execute corresponding operation according to the control instruction. In this embodiment, a control instruction for adjusting the boiler load or the valve opening is transmitted to a control loop of the controlled device as a control signal, and when the control loop is triggered by a signal, the control instruction is immediately executed.
The gas-steam boiler and the intelligent valve execute corresponding operations, the execution result is fed back to the terminal equipment, and the terminal equipment adjusts the target steam parameter according to the execution result so as to output a more accurate control command to be issued to the controlled equipment.
Further, if the feedback execution result is that the supply of the industrial steam meets the requirement of an energy consumption unit after the equipment is regulated, the supply and demand balance is determined, and the current running state data of the steam is continuously monitored. And if the supply and demand are not balanced after the equipment is regulated and controlled, feeding back an execution result to the remote control platform, and updating the control target steam parameter by the remote control platform based on the acquired running state data and the fed-back result. As an example, if the real-time steam temperature is 180 ℃, the actually required steam temperature is 200 ℃, the current target steam temperature needs to be updated to 200 ℃, and a control instruction is issued to the execution terminal for regulation and control until the supply and demand balance is achieved.
According to the technical scheme provided by the embodiment of the disclosure, the operation state data of the steam recovery scheduling system is monitored and acquired in real time, the operation state data is subjected to data processing, an output steam parameter is determined, a target steam parameter is set according to production process requirements, whether supply and demand of industrial steam are balanced or not is judged based on the output steam parameter and the target steam parameter, and if the supply and demand are unbalanced, a control instruction is generated and issued. The industrial steam scheduling and management system can effectively schedule and manage the industrial steam according to the energy demand, so that the supply and demand of the industrial steam are matched, the gradient utilization of energy is realized to the maximum extent, the energy utilization rate is improved, the production cost of an energy consumption unit can be reduced, and the benefit can be increased for an energy supply unit.
