Integrated unit operating device for water treatment

Abstract

The invention discloses an integrated unit operating device for water treatment, belonging to the technical field of water treatment and solving the technical problems of complex structure, long liquid-flowing passage, nonuniform liquid distribution, short service life and high regeneration cost of the existing unit operating device. The integrated unit operating device comprises a tank body, wherein the tank body is sequentially provided with a liquid distribution device, a filler layer and a liquid-collecting device from top to bottom; the liquid distribution device comprises a liquid distribution trough plate and a liquid distribution filter plate; the liquid-collecting device comprises a liquid-collecting trough plate and a liquid-collecting filter plate; the liquid distribution trough plate is provided with a liquid inlet passage located in the center of the liquid distribution trough plate and a liquid distribution guiding trough extending from the liquid inlet passage to the edge of the liquid distribution trough plate; and the liquid-collecting trough plate is provided with a liquid outlet passage located in the center of the liquid-collecting trough plate and a liquid-collecting guiding trough extending from the liquid outlet passage to the edge of the liquid-collecting trough plate. The integrated unit operating device is applied to a water treatment system, such as water treatment equipment using an ion exchange and chromatographic technology.

Description

【Technical field】 [0001] The invention relates to water treatment equipment, in particular to an integrated water treatment operation device, which belongs to the technical field of water treatment. 【Background technique】 [0002] In the technical field of water treatment, the unit water treatment operation device usually includes an ion exchange device and a chromatographic column. In recent years, the preparation of pure water by ion exchange has been widely used in the preparation of industrial ultra-pure water and high-purity water such as pure water for electronics, high-purity water for electric power, ultra-pure water for chemical electroplating, boiler feed water, and ultra-pure water for medicine. One of the irreplaceable means currently used to prepare ultra-pure water and high-purity water. The ion exchange device is carried out in the electrolyte solution through the ion exchange resin, which can remove various anions and cations in the water. Ion exchangers are...

Problems solved by technology

[0004] The traditional ion exchange device usually has a column height of more than two meters, and its height-to-diameter ratio is at least 5:1, while the height-to-diameter ratio of the chromatography column is generally between 10:1 and 50:1. These two unit water treatment operations The liquid passage of the device is long; the liquid distribution device adopts the liquid distribution pipe type with through holes, and the liquid collection device adopts the orifice water cap type, and the drainage cap often falls off, damages, ruptures, and is blocked; in addition, in order to prevent If the filler blocks the drain cap, it is usually necessary to install a filler catcher and replace the drain cap regularly. Generally speaking, these two unit operation devices have complex structures, long liquid passages, uneven liquid distribution, short service life, and high regeneration costs. shortcoming
