It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one.
The following describes an anti-blocking method, device, system and electronic equipment for a sea pipeline of a polar vessel provided by the invention with reference to fig. 1 to 4.
As shown in fig. 1, the method for preventing blockage of a sea pipeline of a polar vessel according to the embodiment of the present application includes: step 110 and step 120.
And 110, acquiring the absolute value of the difference between the real-time flow of the seawater in the sea pipeline and the required flow of the cooling system.
In the step, seawater is taken as a cooling medium and enters a cooling system through a sea pipeline; the real-time flow of the seawater in the sea pipeline is detected by a flowmeter in the sea pipeline.
The required flow rate of the cooling system depends on the actual working condition of the polar ship, for example, when the running speed of the polar ship is higher, correspondingly, the higher the power of the power equipment of the polar ship is, the more heat the power equipment generates, the more cooling medium is needed, that is, the larger the required flow rate is; the specific determination manner of the demand flow is explained in the following embodiments, and will not be described herein again.
The detected real-time flow is sent to the controller, an operator can input required flow to the controller, and the controller is used for comparing the magnitude relation between the real-time flow and the required flow and calculating the absolute value of the difference value between the real-time flow and the required flow.
The target quantity is positively correlated with the absolute value of the difference, and it can be understood that the larger the absolute value of the difference is, the larger the difference between the real-time flow and the required flow is, and accordingly, the more the target quantity is; the smaller the absolute value of the difference is, the smaller the difference between the real-time flow rate and the demanded flow rate is, and accordingly, the smaller the target number is, for example, when the absolute value of the difference is smaller, the number of the heating devices may be increased or decreased by taking the number 1 as one adjustment unit, and when the absolute value of the difference is larger, the number of the heating devices may be increased or decreased by taking the number 2 as one adjustment unit, thereby improving the adjustment efficiency of the number of the heating devices that are turned on.
In the step, the heating device is used for heating the seawater in the sea pipeline, ice slag in the seawater is melted under the heating action, and therefore the blockage phenomenon of the sea pipeline caused by the accumulation of the ice slag is avoided.
The water pump is arranged between the cooling system and the sea pipeline, seawater in the sea pipeline flows into the cooling system under the action of the water pump, and therefore the precondition for judging the size relation between the real-time flow and the required flow is that the inflow of the current water pump is determined to be not less than the required flow, namely the influence of the water pump on the real-time flow in the sea pipeline is eliminated, and the real-time flow only depends on the blockage degree of ice slag on the sea pipeline.
Under the condition that the real-time flow is not less than the required flow, it can be understood that the real-time flow is greater than the required flow, or the real-time flow is equal to the required flow; at this moment, show that the real-time flow of sea water in the pipeline of passing through the sea can satisfy cooling system's cooling demand, the circulation of sea water in the pipeline of passing through the sea is more unobstructed, the ice sediment in the sea does not cause the jam to the pipeline of passing through the sea, then can judge that the total heating power of heating device can satisfy melting of ice sediment this moment, can suitably reduce the quantity of opening of heating device, thereby reduce the total heating power of heating device, make the total heating power of heating device just can satisfy melting demand of ice sediment, until real-time flow equals with demand flow, and then reduce the quantity of opening of heating device as far as possible under the condition that satisfies cooling system's cooling demand, in order to reduce the whole energy consumption of polar region boats and ships.
Under the condition that real-time flow is less than the demand flow, at this moment, show that the real-time flow of the sea water in the pipeline of leading to the sea can't satisfy cooling system's cooling demand, the circulation of the sea water in the pipeline of leading to the sea is more for blocking, the ice sediment in the sea water has caused the jam to the pipeline of leading to the sea, then can judge that the total heating power of heating device can't satisfy melting of ice sediment this moment, need suitably increase the quantity of opening of heating device, thereby promote the total heating power of heating device, in order to melt the ice sediment in the pipeline of leading to the sea, make the sea water can unobstructed flow, it equals to make real-time flow and demand flow, and then reduce the quantity of opening of heating device as far as possible under the condition that satisfies cooling system cooling demand, in order to reduce the whole energy consumption of polar region boats and ships.
According to the anti-blocking method for the sea pipeline of the polar ship, provided by the embodiment of the application, the blocking degree of the sea pipeline caused by ice slag can be judged through comparison between the real-time flow and the required flow of the seawater in the sea pipeline, and the number of the heating devices to be started is increased or reduced according to actual conditions, so that the number of the heating devices to be started is reduced as far as possible under the condition that the cooling requirement of a cooling system is met, and the overall energy consumption of the polar ship is reduced.

In this step, the ambient temperature is inversely related to the number of the heating devices that are turned on, and it can be understood that the lower the ambient temperature is, the lower the temperature of the seawater is, and accordingly, the more the ice in the seawater is, the more the heating devices need to be turned on to melt the ice; the higher the ambient temperature, the higher the temperature of the seawater, and accordingly, the less the ice in the seawater, and the fewer heating devices need to be turned on to melt the ice.
Therefore, the corresponding relation between the environment temperature and the starting number of the heating devices can be obtained through experiment or theoretical calculation in advance, and the corresponding starting number of the heating devices can be obtained according to the environment temperature.
A method of acquiring the required flow rate of the cooling system will be described below.
The required flow depends on the heat dissipation capacity of the heat source equipment on the polar ship in unit time, the heat dissipation capacity in unit time depends on the power of the heat source equipment, the power of the heat source equipment is mainly determined by the implementation speed of the polar ship, the higher the real-time speed is, the higher the power of the heat source equipment is, the lower the implementation speed is, and the lower the power of the thermal original equipment is.
The real-time speed of the polar region ship is firstly obtained, and the real-time speed can be calculated through sound wave emission and reception or through GPS satellite positioning.
The power of the heat source equipment is determined based on the real-time navigational speed, wherein the heat source equipment comprises power equipment, the real-time navigational speed is in positive correlation with the power of the heat source equipment, and the corresponding relation between the real-time navigational speed and the power of the heat source equipment can be calibrated in advance, so that the power of the heat source equipment can be obtained according to the real-time navigational speed.
