Example two
Fig. 2 is a schematic flow diagram of a method for monitoring cooling water of a smelting furnace according to an embodiment of the present disclosure. As shown in fig. 2, the method for monitoring cooling water of a smelting furnace in the present embodiment is mainly applied to the system 100 for monitoring cooling water of a smelting furnace in the first embodiment, and includes the following steps:
s101, detecting first operation data of a first pipeline communicated with the target cooling unit by using the first detection assembly.
When the working state of the cooling unit in the cooling assembly is monitored by using the monitoring system for cooling water of the smelting furnace in the first embodiment, the first detection assembly can be used for detecting the first operating data of the first pipeline communicated with the target cooling unit. Optionally, the first operational data includes at least one of temperature, pressure, and flow rate.
Optionally, as shown in fig. 3, the method comprises the following steps:
s201, controlling a flow dividing valve connected with the target cooling unit to conduct the target cooling unit and the first detection assembly.
After the staff issues the monitoring instruction of monitoring the target cooling unit, the control assembly controls the flow divider valve connected with the target cooling unit to conduct the target cooling unit and the first detection assembly. That is, the second end of the shunt valve is closed and the third end of the shunt valve is opened.
S202, controlling to disconnect the remaining shunt valve connected with the first detection assembly from the first detection assembly.
After the monitoring instruction of the target cooling unit is issued by the worker, the control assembly controls to disconnect the connection between the residual flow dividing valve connected with the first detection assembly and the first detection assembly, so that the first detection assembly only monitors the working state of the target cooling unit. That is, the second ends of the other shunt valves connected to the first sensing assembly are opened or maintained in an open state; and the third end of the other shunt valve connected with the first detection assembly is closed or kept in a closed state.
S203, detecting first operation data of the first pipeline by using the first detection component.
After the target cooling unit is connected with the first detection assembly and the rest of the shunt valve connected with the first detection assembly is disconnected from the first detection assembly, the first operation data of the first pipeline can be detected by the first detection assembly.
And S102, evaluating the working state of the target cooling unit according to the first operation data.
After the first operation data is detected, the working state of the target cooling unit can be evaluated according to the first operation data.
As a possible implementation, as shown in fig. 4, the method includes the following steps:
s301, obtaining historical operating data of the first pipeline.
The first detection component detects that the operation data is stored in a memory in the system every time, so that the current historical operation data of the first pipeline can be directly called from the memory.
S302, obtaining a deviation value between the first operation data and the historical operation data.
And comparing the first operation data with the historical operation data to obtain a deviation value between the first operation data and the historical operation data. Alternatively, the deviation values may be, but are not limited to, differences, ratios, and the like.
And S303, determining the working state of the target cooling assembly according to the deviation value.
After the deviation value is determined, the working state of the target cooling unit can be determined according to the deviation value. If the deviation value is within the preset range, the working state of the target cooling unit can be determined to be good and meet the expectation; when the deviation value is outside the preset range, it can be determined that the operation state of the target cooling unit is poor.
In some embodiments, in order to evaluate the working efficiency of the cooling unit, the data detected by the first detection assembly and the second detection assembly may be compared to determine the working efficiency of the cooling unit. As shown in fig. 5, the method comprises the following steps:
s401, detecting second operation data of a second pipeline where a second detection assembly is located by using the second detection assembly.
After the water supply pipeline and the water return pipeline are communicated, the second detection component can detect second operation data of the second pipeline where the second detection component is located. Optionally, the second operational data includes at least one of temperature, pressure, and flow rate.
S402, determining the working efficiency of the target cooling unit according to the first operation data and the second operation data.
And comparing the first operating data with the second operating data to determine the working efficiency of the target cooling unit. For example, the cooling efficiency of the target cooling unit can be determined by performing a mathematical operation on the temperatures measured by the two.
Alternatively, the wear level of the target cooling unit may be determined according to the first operation data, the second operation data and the set parameter value of the target cooling unit to know the change condition of the target cooling unit and determine whether to replace the target cooling unit. For example, when the determined cooling efficiency of the target cooling unit is greatly different from the set cooling efficiency, it can be determined that the degree of wear of the target cooling unit is high, and the target cooling unit needs to be replaced as soon as possible.
