Special plane slit vortex type desalter filtering device for nuclear power station

Abstract

The invention relates to the technical field of nuclear power stations and in particular relates to a special plane slit vortex type desalter filtering device for a nuclear power station. The plane slit vortex type desalter filtering device consists of an adapter pipe, a water guide port, a sealing tape, a filtering barrel, a sealing ring, a baffle, a sealing side strip, a supporting barrel, a water outlet, a core column, a water guide sleeve, a fastening nut and a plurality of limiting sleeve discs, wherein a fan-shaped filter disc is arranged on the outer side face of each upper positioning ring; an elongated slit is formed in each filter disc; an elastic clamp which is integrated with the corresponding filter disc is arranged on the upper surface of the arc edge of the corresponding filter disc and consists of a cubic block and a rectangular strip; and the cubic block and the upper surface of the corresponding filter disc are integrated. Compared with the prior art, the special plane slit vortex type desalter filtering device has a higher filtering efficiency and mounting efficiency and is good in durability.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a special planar slit eddy current desalter filter device for nuclear power plants. Background technique [0002] The inlets and outlets of the yin bed, yang bed, and wet bed of the water treatment equipment desalter of the existing nuclear power plant are all equipped with filter head devices, also known as water caps, which are used to prevent the passage of ion exchange resins, but can Purified water is passed through to obtain clean water. [0003] The existing filter head structures include wire-wound type and laminated type. The wire-wound filter head is easy to be damaged. When the steel wire is wound, it needs to be fixed on the skeleton by spot welding. The welding deformation is large, the steel wire has low strength and is easy to deform, and the gap between the steel wire and the steel wire is difficult to control. The filter tube of the laminated filte...
