Problems solved by technology

In the process of operation, bed lowering and regeneration, the resin layer of the "double-chamber double-layer floating bed" is prone to disturbance and chaotic layer, which leads to a decrease in resin utilization rate, affects the quality of effluent water, and reduces the cycle water production.
Its main disadvantages are high acid and alkali consumption (most acid and alkali specific consumption is as high as 3.0~5.0), high self-consumption rate, etc.

Embodiment Construction

[0022] The double-chamber floating-full-chamber bed adds a dilution water pipe between the upper chamber and the lower chamber, and the other structures are the same as the double-chamber floating bed. It is designed with sulfuric acid as the regenerating agent on the cation bed, and the sulfuric acid adopts a step-by-step regeneration process. The concentration of sulfuric acid entering the chamber on the positive bed in the first step is 1.5%, the concentration in the second step is 3%, and the concentration of sulfuric acid kept in the lower chamber is 0.7% all the time. To accommodate this step-by-step regeneration process, dilution water is added between the upper and lower chambers. The holes on the dilution water pipe are evenly distributed, and the hole diameter only ensures that the water comes out, and the resin cannot go in. If common hydrochloric acid is used as the regeneration agent, its structure does not need to be changed, that is, it does not need to dilute ...

Abstract

The double-chamber bed incldues a lower floating chamber bed and the upper full chamber bed. The upper full chamber bed has a filling rate of 100%. The present invention has greatly raised water yield, low consumption and good regeneration effect.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a double-chamber "floating-full-chamber bed". Background technique [0002] Most domestic boiler water treatment devices still use fixed-bed downstream or countercurrent regeneration processes. [0003] At present, the mainstream foreign water treatment processes are basically occupied by "floating bed" and "full chamber bed", among which "floating bed" accounts for more than 70%. The most typical representative of "floating bed" is "double-chamber double-layer floating bed". The lower chamber is filled with weak acid type (yang bed) or weak base type (yin bed) resin, and the upper chamber is filled with strong acid type (yang bed) or strong base type (yin bed) resin. "Double-chamber double-layer floating bed" has the advantages of high operating flow rate, low bed resistance, good water quality and low consumption of regenerant. However, the weak acid ...
