Modularized double-bed ionic exchange apparatus

Abstract

The invention discloses a modular double fluidized bed ion exchange device, which comprises a standardized box body, wherein, the box body is of a rectangle, both ends of the box body are respectively and vertically provided with three identical connecting short pipes with flanges, a fixed upper ion exchange resin bed and a fixed lower ion exchange resin bed are arranged in the box body, the upper ion exchange resin bed is positioned between the upper connecting short pipes and the intermediate connecting short pipes, the lower ion exchange resin bed is positioned between the intermediate connecting short pipes and the lower connecting short pipes, the intermediate connecting short pipe on the front end of the box body is an inlet of water to be treated, the upper connecting short pipe and the lower connecting short pipe on the rear end of the box body are water outlets after ion exchange, the upper connecting short pipe and the lower connecting short pipe on the front end of the box body are inlets of backwashing water, and the intermediate connecting short pipe on the rear end of the box body is an outlet of the backwashing water. The device can be arbitrarily assembled with treatment devices of other box bodies with the same specification, which contributes to reducing cost, being convenient for installation, guaranteeing the treatment effect of water, and performing backwashing. The device can be used for sewage treatment in the environmental protection field or water purification in the chemical field.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a modular double-fluid bed ion exchange device, which can be used in the technical fields of environmental protection and chemical engineering. Background technique [0002] The existing sewage treatment equipment is basically designed for a certain sewage discharge source, and is suitable for this sewage treatment but not for other sewage sources. Therefore, due to the different amount of sewage discharged from different sewage sources, a single sewage treatment system cannot be adapted to the sewage treatment of various sewage discharge sources, and the pre-production of various sewage treatment systems with different specifications not only requires more cost in design and production Large, and the treatment process for different sewage may also have different, so the adaptability of the pre-designed and produced treatment equipment will have problems. Therefore, in order to reali...
