Detailed Description

The technical scheme of the utility model is further described in detail with the accompanying drawings and the specific implementation mode:

as shown in figure 1, the intelligent filtering device for the heat exchange station comprises a primary filtering system (33) and a secondary filtering system (34), wherein a sewage discharge pipeline I (15) is arranged on the primary filter (12), a sewage discharge pipeline II (31) is arranged on the secondary filter (29), and an outlet pipeline I (22) of the primary filtering system (33) is connected with an inlet pipeline II (16) of the secondary filtering system (34).

The utility model discloses a concrete working process does:

when filtration system normally worked, hot water got into elementary filtration system from inlet pipeline I, and during normal work, controller II and controller IV controlled solenoid valve II and solenoid valve IV respectively were in the closed condition, and controller I and controller III controlled solenoid valve I and solenoid valve III respectively were in the open condition this moment, and consequently, hot water gets into elementary filter from water inlet I, under the effect of water pressure, flows from elementary filter screen export through elementary filter screen, through I outflow of outlet pipeline. After working for a period of time, impurity in the hot water will be kept off in the outside of the primary filter screen of primary filter to influence the flow and the pressure of rivers, and then cause inlet pressure to be greater than outlet pressure, if do not handle this moment, probably the filter screen can block up, brings bigger trouble.

In view of the above reasons, pressure sensors are arranged at the inlet and the outlet of the primary filter, the measured values of the pressure sensors at the inlet and the outlet are compared, when the difference value of the two measured values exceeds a certain threshold value, the controller I and the controller III respectively control the electromagnetic valve I and the electromagnetic valve III to be closed, and the controller II and the controller IV respectively control the electromagnetic valve II and the electromagnetic valve IV to be opened, so that the primary filter enters a cleaning mode, and impurities and blockages are washed off and discharged from a sewage discharge pipeline by reversely washing the filter screen. When the water quality discharged by the sewage discharge pipeline is recovered to be normal, the electromagnetic valve II and the electromagnetic valve IV are closed again, the electromagnetic valve I and the electromagnetic valve III are opened simultaneously, and the normal filtering mode is entered again.

When hot water enters the secondary filtering system, the basic working principle is the same as that of the primary filtering system, and the difference is that the mesh diameter of the secondary filtering net is smaller than that of the primary filtering net, so that the secondary filtering net can effectively filter fine impurities.

Through the effective filtration of the primary and secondary two-stage filtration systems, the water quality entering the subsequent nodes of the heat supply pipe network can be greatly improved, so that the failure probability of the subsequent nodes is reduced, and the expected filtration effect is achieved.
