    Equipment for filtering the cooling-water in a power-station condenser system comprises a cylindrical sieve housing (1), forming part of a duct and enclosing at least one sieve basket assembly (2) axially aligned with the housing axis (3). The basket assembly is divided into two or more sectors which act in parallel by partition (8), and a flap valve (10) enables each sector in turn to be isolated from the upstream side of the housing to suspend the forward flow therethrough. Each sector has a valve (11) which is then opened, so that water filtered through the other sector (5) backwashes the sieve in the isolated sector and carries debris out through that valve (11). Sieve baskets may be of various shapes, and a four- sector arrangement is exemplified. <IMAGE>

    The invention relates to the purification of cooling water, in particular to devices for the mechanical purification of the flow of cooling water in condensers of power plants.
    The purpose of the invention is to increase the reliability of the device.
    FIG. 1 shows the device a general view; in fig. 2 - the same, top view; in fig. 3 shows the valve assembly of the device, a general view of FIG. 4 - device with four sectors and valve node, axial section; in fig. 5 - the same, top view.
    The device comprises a cylindrical body 1, mounted parallel to the axis of the body of the partition 2, dividing the body cavity into four chambers 3, the backwash tool 4, consisting of the damper 5 installed with the possibility of rotation and the wastewater discharge pipe 6 equipped with shut-off valves 7 and located between the valve 5 and the screen surfaces. The damper device consists of 8 semi-valves installed on a joint shaft, shifted by 90. The sieve surfaces are made of a carrying bottom 9 and cylindrical boxes 10 mounted on it, equipped with head plates 11. The case has two diametrically intersecting partitions 12, which are divided into four chambers 13, controlled by semi-valves 14, having the shape of a quadrant. The partitions 12 are made with a height at least corresponding to the height of the boxes 10 and divide the carrier bottom 9 into sections 15 corresponding to chambers 13. The valve assembly is designed so that during the normal operating position of the semi-valves 14 the shut-off valves 7 close the outlet opening and in position backwash - open the outlet.
    The device works as follows.
    The flow of cooling water passes through the housing 1 in the axial direction i.e. he enters the body axially and axially out of it. When one of the sections 15 is closed (Fig. 1), the corresponding outlet 6 outlet

    the sewage is open, and the other branch - 1TSI branch pipe 6 is closed. Flows created under this condition are shown by arrows 16. It can be seen that the flow of cooling water flows in one direction through the device, cleaning it. In this case, a partial flow is discharged, causing backwashing in the direction of the arrows 16, not only the cylindrical box 10, but also the head plates 11 and the carrying bottom 9 are cleaned in the corresponding chamber from contaminants discharged through the branch pipe 6 of the outlet. The carrier bottom 9 is located along the entire cross section of the housing 1. By performing the head plate 11, the cylindrical boxes 10 and the carrier bottom 9 in the form of a sieve, the filtering surface is greatly enlarged. The sieve surface is subjected to backwash in a simple way without performing relative movement, due to the location of the barriers 12 and the controllable valve assembly, hydrodynamic conditions are created, causing backwashing simultaneously and autogenously.
