Abstract

The invention is intended for installation in pipelines and m. used to purify water entering the steam turbine condenser. The purpose of the invention is to increase the reliability of the filter by improving the cleaning efficiency of the mesh element of the filter. The conical AE 4 is reversed in the opposite direction to the water flow and installed in the conduit 1. Inside the AE, the collector 5 of purified water is placed with the possibility of rotation with spraying nozzles arranged along a helical line, grouped in groups 12,13,14,15. The groups are arranged in a shahmatny order regarding the collector. The chamber (K) 17 is made between the base of the ESS and the water line to collect a load, and the opposite — K 19. The nozzles 20 are installed in K 19 and oriented towards the ESS. With an increase in the pressure drop across the SC by a factor of 1.5, water under pressure is supplied to the manifold and the nozzles. As a result, the water entering through the spray nozzles into the ESS otvergoet: aggregates accumulating on the outer surface of the ESS. With the help of nozzles 20, the contaminants are discharged from the upper part of the ESS in and in 100 U - in K 17. 3 Il. (L with

Claims (1)

Claim The filter is mainly for cleaning the water entering the condenser * of the steam turbine, containing a conical mesh element facing the water flow with its apex facing the water stream and placed inside the latter with the possibility of rotation of the treated water collector with spray nozzles for regenerating the mesh element made between the base of the conical element and a water conduit for collecting contaminants with a branch pipe for their removal, characterized in that, in order to increase reliability by * improving efficiency cleaning the mesh element - the filter element, the latter is additionally equipped with a chamber mounted opposite to the pollution collection chamber and flush nozzles placed in it and oriented in the direction of the mesh element and connected in parallel to the purified water collector, and the spatter nozzles are combined into groups diametrically staggered relative to the collector and mounted along a helical line. 14 24 ϊ 78
