Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention discloses a water-saving control method and a water-saving control system for a hot-rolled water system pipe network, which are mainly used for saving water for the hot-rolled water system pipe network.
For the purpose of illustrating and explaining the present invention, a schematic diagram of a hot water system pipe network according to this embodiment will be described with reference to FIG. 1.
In fig. 1, a water supply plant uses a pipeline to access purified water, and a metering device (schematically shown as trade settlement points in fig. 1) is arranged on the pipeline and provides water for each backbone network. In fig. 1, a hot-rolled water system pipe network is simplified, branches are deleted, clear backbone networks are formed, and each backbone network is provided with a metering instrument (shown as an in-plant metering point in fig. 1) for data acquisition, tracking and analysis. Each backbone network comprises: the system comprises a dining room, a refrigerating station, a north 2 door (water network), an air conditioner user IC3, a heating furnace cooling circulation system (A system), a laminar flow system (B system), a main rolling line system (C system), a sludge system (D system), an instrument system (E system) and an oily wastewater system (F system). Wherein the B system and the C system are used as a net ring system; the D system and the F system are used as turbid ring systems.
In order to save water consumption, the embodiment only reserves one new water supplementing point for the system in each main network, and improves the layout of the hot-rolled water system pipe network disclosed above. Specific layout improvement referring to fig. 2, is: 1. the system A and the system C are connected, so that the surplus water of the system A can supplement the system C. 2. The B system and the C system are communicated, so that water of the B system and water of the C system are mutually supplemented, in particular, redundant water of the C system can be supplemented to the B system, and backwash water of a filter of the B system can be supplemented to the C system, so that the water of the B system and the water of the C system are mutually supplemented. 3. And the D system and the F system are both connected with the C system, so that surplus water of the D system and the F system can be used for supplementing the C system. On the basis of the layout improvement, the water flow direction from the turbid ring system to the clean ring system can be opened, and water resources are saved.
On the basis of the improved layout, referring to fig. 2, a flow chart of an implementation of the water saving control method of the hot-rolled water system pipe network disclosed in this embodiment is provided, and a step water supplementing strategy is executed in combination with water consumption and water quality monitoring data, so as to form an optimal water consumption mode of the water system, and lead water consumption indexes of industry.
The method of the present embodiment includes the steps of:
step 110, obtaining water consumption of each main network in the hot-rolled water system pipe network.
In this embodiment, each backbone network performs branch pruning according to fig. 1, and a metering device is installed to monitor water consumption of each backbone network. Therefore, in a specific implementation process, the water consumption of each backbone network is monitored by using the metering devices installed in each backbone network. A table of records of water consumption for each backbone network is presented in table 1 (specific values not shown).
TABLE 1
Step 111, determining whether the water consumption of each backbone network meets a preset condition.
The preset conditions of the present embodiment are set with trade settlement amounts and standard consumption amounts of the respective backbone networks. Trade settlement amounts are used as a comparison standard for water consumption of all backbone networks. Whereas the standard consumption is used as a comparison of the consumption of the individual backbone networks. Of course, each backbone network has a respective different standard consumption.
In a specific judging process, two judging strategies are provided.
The first judgment strategy is: the total water consumption of all backbone networks is compared with the trade settlement. Specifically, the total amount of water consumption is determined based on the water consumption of each backbone network. And judging whether the difference value between the total water consumption amount and the trade settlement amount is smaller than or equal to a first difference value threshold value. For example, whether the difference between the two is 0 or whether the difference between the two is less than 0.1 ton. If yes, the water consumption of each backbone network meets the preset condition. If not, the measurement abnormality exists, for example, the measurement abnormality caused by pipe network water leakage. And prompting to examine each backbone network.
The second judgment strategy is: each backbone network is compared to its standard consumption. Specifically, it is determined whether a difference between the water consumption of each backbone network and the standard consumption of each backbone network is equal to or less than a second difference threshold. The water consumption of each backbone network may be judged one by one or may be judged in parallel, for example, whether the water consumption of each backbone network is consistent with the standard consumption of each backbone network is judged one by one (whether the difference between the water consumption and the standard consumption is 0). If all the main networks are satisfied, the water consumption of each main network satisfies the preset condition. If any backbone networks are inconsistent, prompting to conduct targeted investigation on the backbone networks which are not met, and therefore rapidly remedying the abnormal points.
The two judging strategies can be used alternatively or in parallel. According to the embodiment, by setting one or more guarantees, the pipe network leakage points and metering anomalies are found rapidly, and the invisible water system pipe network is ensured to run stably and consume is controlled.
And step 112, if yes, acquiring water quality monitoring data of each backbone network.
In this embodiment, each backbone network is provided with a water quality monitoring instrument for monitoring the water quality of each backbone network, and the water quality monitoring table of each backbone network is referred to in table 2 (the clean ring system and the turbid ring system are shown, of course, the two systems can be subdivided, and specific numerical values are not shown).
TABLE 2
And 113, if the water quality monitoring data of each backbone network meets the water quality detection standard, implementing a step water supplementing strategy by using each backbone network so as to save water consumption.
In this embodiment, the water quality monitoring data of each backbone network is detected by using the water quality detection standard of each backbone network, and the purpose of the water quality detection is to determine whether the water in each backbone network can be recycled. If the water quality detection of each backbone network does not reach the standard, water quality treatment can be carried out, so that the water quality detection of each backbone network reaches the standard for recycling. If the water quality detection reaches the standard, the water consumption of each main network is recycled, and the cascade water supplementing strategy is implemented by using each main network, so that the water consumption is saved.
Therefore, the precondition for implementing the cascade water replenishing strategy is that the water consumption of each backbone network is normal, and the water quality of each backbone network must reach the standard, for example, when the B system and the C system are mutually replenished, the water quality of the B system needs to meet the water quality requirement of the C system. Similarly, when the D system and the F system are used for supplementing water for the C system, the water quality requirement of the C system also needs to be met. And implementing a step water replenishing strategy according to water consumption and water quality monitoring data of each main network, so that an optimal water consumption mode of the water system is formed, and water consumption indexes of industries are led.
In the process of implementing the cascade water replenishing strategy by utilizing each backbone network, the cascade water replenishing strategy mainly comprises two systems. Specifically, a cascade water replenishing strategy aiming at a laminar flow system is implemented by utilizing each backbone network; and implementing a step water supplementing strategy for the main rolling line system by utilizing each main network.
In the process of implementing the cascade water replenishing strategy aiming at the main rolling line system by utilizing each main network, the water replenishing requirements of the main rolling line system are different, and the determined water replenishing strategies are different in level. And determining a corresponding level water replenishing strategy from the step water replenishing strategies aiming at the main rolling line system according to the water replenishing demand quantity of the main rolling line system.
Wherein the step replenishment strategy for the main mill train system is determined by one or more of a heating furnace cooling circulation system, a laminar flow system, a sludge system, and an oily wastewater system.
In the cascade water replenishing strategy, referring to fig. 2, surplus water of any one of the system a, the system B, the system D and the system F forms a primary water replenishing strategy; the surplus water of any two systems of the A system, the B system, the D system and the F system forms a secondary water supplementing strategy; the surplus water of any three systems of the A system, the B system, the D system and the F system forms a three-level water supplementing strategy; the surplus water of the system A, the system B, the system D and the system F forms a four-level water supplementing strategy, so that different water demands of the system C are met.
Of course, the present embodiment may set the system priority to implement the cascade water replenishment strategy. For example, the surplus water of the A system is preferentially used as the primary water replenishing strategy, the surplus water of the A system and the B system is preferentially used as the secondary water replenishing strategy, and if the water requirement of the C system becomes larger, the water supply of the turbid ring system is added.
In the process of implementing the cascade water replenishing strategy for the laminar flow system by utilizing each backbone network, determining the corresponding grade water replenishing strategy from the water replenishing strategy for the cascade laminar flow system according to the water replenishing demand of the laminar flow system.
The cascade water supplementing strategy for the laminar flow system comprises a water supplementing strategy determined by using surplus water of the main rolling line system and a water supplementing strategy determined by the main rolling line system in combination with one or more of a cooling circulating system of a heating furnace, a sludge system and an oily wastewater system.
In the cascade water replenishment strategy, referring to fig. 2, the surplus water of the c system forms the primary water replenishment strategy. On the basis of water supply of the system C, the surplus water of any one of the system A, the system D and the system F is combined to form a secondary water supplementing strategy, the surplus water of any two of the system A, the system D and the system F is combined to form a tertiary water supplementing strategy, and the surplus water of the system A, the system D and the system F is combined to form a quaternary water supplementing strategy.
Of course, the present embodiment may set the system priority to implement the cascade water replenishment strategy. For example, the surplus water of the C system is preferentially used as the primary water replenishing strategy, the surplus water of the A system and the C system is preferentially used as the secondary water replenishing strategy, and if the water requirement of the B system becomes larger, the water supply of the turbid ring system is added.
Because the cascade water replenishing strategy needs the water quality to reach the standard, the water quality of each backbone network is monitored in real time when the cascade water replenishing strategy is implemented. If the water quality of the main network does not reach the standard, stopping the water supply of the main network and performing water quality treatment until the water quality reaches the standard.
The purpose of the step water replenishing strategy is mainly to save water consumption. On the basis, the water quality of each main network can be concentrated, and the water recycling rate of each main network can be improved. Specifically, whether the water recycling rate of each backbone network reaches a preset threshold value or not is judged, for example, whether the water recycling rate is more than or equal to 97%, and if so, the wastewater can be discharged.
Based on the same inventive concept, the following embodiments disclose a water saving treatment system of a hot rolled water system pipe network, referring to fig. 4, comprising:

The bus interface 100 may also link together various other circuits such as peripheral devices, voltage regulators, power management circuits, and the like.
