High-speed mixing bed adopting spiral fluid director water distribution plate and hexagonal unit perforated plate

Abstract

The invention provides a high-speed mixing bed adopting a spiral fluid director water distribution plate and a hexagonal unit perforated plate. The high-speed mixing bed comprises an arc-shaped top shell, a fan blade plate type water distribution plate and a water distribution perforated plate, wherein a water inlet is formed in the top end of the arc-shaped top shell, the fan blade plate type water distribution plate is arranged right below the water inlet, the water distribution perforated plate is arranged right below the fan blade plate type water distribution plate, the fan blade plate type water distribution plate comprises a central block and a plurality of upwarp fan blade plates which are uniformly connected to the central block, the water distribution perforated plate comprises a plurality of hexagonal unit plates and a plurality of arc-shaped plates, the hexagonal unit plates are spliced together, and the arc-shaped plates are spliced on the peripheries of the hexagonal unit plates. The high-speed mixing bed adopting the spiral fluid director water distribution plate and the hexagonal unit perforated plate has the advantages of scientific design, high water distribution uniformity, long service life and high purification efficiency.

Description

technical field [0001] The invention relates to a high-speed mixed bed, in particular to a high-speed mixed bed adopting a spiral deflector water distribution plate and a hexagonal unit porous plate. Background technique [0002] The high-speed mixed bed is also called a high-speed ion exchanger. Its principle is to place anion and cation exchange resins in the exchanger, so that the raw water passes through the anion exchange resin to remove anions in the water, and the cation exchange resin to remove cations in the water to obtain pure water. The existing spherical high-speed mixed bed has the following disadvantages: (1) A simple dome-shaped water distribution plate is used to distribute the raw water at the water inlet, which makes the distribution of raw water uneven. The lower part is relatively sparse and the surrounding area is denser, so the porous plate below is prone to deformation due to uneven force, and the raw water flows into the resin layer from the deformed...

Problems solved by technology

The existing spherical high-speed mixed bed has the following disadvantages: (1) A simple dome-shaped water distribution plate is used to distribute the raw water at the water inlet, which makes the distribution of raw water uneven. The lower part is relatively sparse and the surrounding area is denser, so the porous plate below is prone to deformation due to uneven force, and the raw water flows into the resin layer from the deformed part of the porous plate, which will cause most of the resin to fail, resulting in a reduction in the water production of the spherical high-speed mixed bed; (2) Due to the limited area of ​​the manhole on the high-speed mixed bed, the existing perforated plate is divided into several strip plates, which are handed in from the manhole and then assembled. This long strip structure is due to the area of ​​the middle plate Relatively large, low strength, easy to be impacted and deformed by raw water, and due to the need for butt joints on both sides, water caps cannot be placed at the joints, resulting in limited uniformity of holes, and poor uniformity of raw water after passing through the perforated plate.
