Abstract

Equipment for filtering of cooling water flowing from power station condensers comprises a cylindrical sieve housing (1) enclosing a plurality of sieve portions (4) positioned obliquely to the direction of flow and located in different sections of the housing, each sieve portion being backflushed in turn by closing an upstream shutter 7, to stop the main flow to that housing section, and opening a corresponding valve 5 to discharge backflush water and debris. Each housing section may have its own shutter 7, combined with the corresponding discharge valve 5. Sieve portions may be pleated (Fig. 9 not shown). <IMAGE>

The invention relates to devices for the mechanical purification of the flow of cooling water to power plant condensers. The purpose of the invention is to simplify maintenance while ensuring compactness. FIG. 1 shows the device a general view; in fig. 2 shows section A-A in FIG. ; in fig. 3 - damper, axon metri; in fig. 4 - sieve fixture., General view; in fig. 5 - the same, option; in fig. 6 - the proposed device, axial incision; in fig. 7 is a section BB in FIG. 6; in fig. 8 - device, axonometrics. The device for mechanically cleaning the cooling water flow of the power plant condensers consists of a cylindrical body 1, a sieve attachment having a plurality of sieve surfaces 2 inclined to the flow direction of the water flow, connected to each other, and means 3 for backwashing the sieve surfaces. By means of the screening surfaces 2, the casing is divided into at least two chambers 4 and 5, to which nozzles 6 are connected for from sewage water with valves 7. Means for backwashing 3 consists of a damper 9 installed with possible turning on the axis 8 and nozzles 6 for removal of sewage, equipped with a valve 7. The shutter device 9 is made in the form of two quadrant-shaped valves, offset from each other by 90. The nozzles 6 of the wastewater drainage from the chambers are installed radially in the wall of the housing and are located between the valve device 9 and the sieve surfaces 2, obliquely mounted to the main flow direction of the zod. Chambers 4 and 5 may have one joint pipe 6; the waste water outlet, which enters the center of housing 1 and is directed outwards through elbow 10. In this case, separate chambers 4 and 5 are alternately connected via valve 7 to pipe 6 for drainage wastewaters (Fig. 6 and 7) i It is advisable to move the damper 9, belonging to one chamber 4, and the valve 7, related to another chamber 5. In the particular case, it is possible to combine the damper 9 and valve 7 of the Xc1 of each chamber into one node (Fig. 6 and 7), when pans 7 are valves, and closing the entrance openings corresponding otkrshayuschimi pipe 6 for waste water disposal. Nozzles 6 in chambers 5 and 4 or a joint nozzle 6 of all chambers are positioned so that when one chamber 4 is closed, the corresponding nozzle is opened to drain the waste water of another chamber 5, and vice versa. The sieve surfaces 2 can be made in the form of a folded system with combs 11 and valleys 12 (FIG. 4) or in the form of a set of truncated cones inserted concentrically into each other with angles of taper directed in different directions and connected by edges of a truncated cone ( Fig. 5). Force surfaces 2 can be made with flanges 12 adjacent to concentric circles in housing 1 and valleys 12. Their length in the axial direction corresponds to the radius of housing 1 (Fig. 8). A device installed directly in front of a power station capacitor operates as follows. The coarse particles contained in the incoming flow of cooling water are retained on the screen surfaces 2. The pressure drop is measured. When the pressure drop caused by coarse particles on the sieve surfaces reaches the value set on the limit value detector, the shutter device 9 moves to the closed position of the chambers 4 and 5 and at the same time opens the wastewater discharge pipe 6. As a result of the pressure differential between the inlet and outlet of the cooling water, a flow is created through the discharge pipe in the bypass to the condenser. In this case, the coarse particles on the screen surfaces 2 are washed away and discharged into the cooling water outlet pipe. Claim 1. Device for mechanical cleaning of cooling water of condensers of a power plant, comprising a cylindrical body, sieve surfaces, by means of which the body is divided at least into two chambers, backwash means consisting of a rotatable valve installed and branch pipes for draining sewage equipped with valves, characterized in that, in order to simplify servicing while ensuring compactness. branch pipes of wastewater from the chambers are located between their damper device and sieve surfaces inclined to the main direction of flow of water. . 2.
