Embodiment Construction

[0017] The present invention proposes a self-cleaning internal differential pressure floating bed, which adopts the principle of internal differential pressure and is used for ion exchange water treatment.

[0018] The floating bed can be widely used in power stations, chemical industry, various boilers, light industry, textile, papermaking and other fields. The present invention aims at the existing problems of the current ion exchange water treatment equipment—the fixed bed and the floating bed, and overcomes the respective defects, and has the advantages of stable operation of the fixed bed and cleaning inside the body, and high operating flow rate and good regeneration effect of the floating bed. The advantage of using less regeneration solution.

[0019] In this self-cleaning internal differential pressure floating bed, the bottom of the tank is the raw water inlet a, and the raw water enters the exchange medium layer 2 through the water distribution device 1, and between...

Abstract

A self-cleaning internal pressure differential floating bed for treating water by ion exchanging method achieves improvement on the basis of the original fixed bed and floating bed. A cleaning space is arranged on the top of the exchanging agent layer and is separated by hole scrubbing board, an aqueduct is induced from the exchanging agent layer and reaches to the top of the hole scrubbing board, partial intake water enters into the cleaning space to form grease pressed water layer through the inducing water device, it forms differential pressure with the water collector of the hole scrubbing board bottom. Its advantages include stable operation, high operating flowing speed and good reutilizing effect.

Description

technical field [0001] The invention belongs to the technical field of ion exchange water treatment, and relates to a self-cleaning internal differential pressure floating bed which is applied to water treatment in power stations, chemical industry, various boilers, light industry, textiles, papermaking, etc., and adopts an ion exchange method. Background technique [0002] There are usually two types of ion exchange water treatment equipment, one is a fixed bed (tank), and the other is a floating bed (tank). [0003] Fixed bed: Raw water flows in and out during operation. The advantage is that the exchanger (resin filler with tiny particles) can be cleaned inside the body, and the dirt after cleaning can be discharged from the body. The change of operating flow rate has little impact on the quality of produced water. Its main disadvantage is that because the raw water flows in from top to bottom, in order to avoid bias flow, the operating flow rate is low, and the flow rate...
