Composite synergic recovering agent for ion exchange resin

Abstract

The invention relates to an ion exchange resin composite cooperate recover agent, formed by following materials (mass percentage) as alkyl phenol at 0-8.0, high-effect penetrant at 0.5-4.5, sodium chloride at 3-10, alcaine at 0-7, acid of wine at 0-2.5, oxidant at 0.4-0.6, non-ionic surface activator at 5.5-10, sodium dithionite at 0-0.1, recover disperser T-225 at 2.5-8.0, and the left is water, or formed by following materials as recover reducer as 0.3-1.0, sodium chloride at 0-1, alcaine at 0-10, combiner at 0-1.2, sludge remover rosin amine at 3-11, caustic soda at 0-2, amphiprotic surface activator at 4-10, symclosene at 7.5-12, recover agent SW-218 at 1.0-2.5 and the left is water. The invention has short recover time, while it can remove high-level metal ion, and high organic removing efficiency, without corrosion on device and harm on people.

Description

technical field [0001] The invention relates to the technical field of resin recovery agents, in particular to an ion exchange resin composite synergistic recovery agent. Background technique [0002] Causes of anion and cation exchange resin pollution poisoning: [0003] 1. The surface of the resin is stained with suspended solids in water, oil impurities, etc. [0004] 2. Pollution and poisoning of yin and yang resins by iron and calcium. [0005] 3. After the organic matter enters the inside of the yin and yang resin, it will be stuck in it. This is also called poisoning. The resin polluted by organic matter will have extremely bad consequences. The cycle water production of the yin bed will drop significantly, the color of the resin will become darker, and the water will be discharged. PH value decreases, conductivity increases, SiO 2 Unfavorable factors such as increased content and increased cleaning water consumption, the organic substances that cause resin polluti...

AI Technical Summary

Problems solved by technology

[0003] 1. The surface of the resin is stained with suspended solids in water, oil impurities, etc.

[0004] 2. Pollution and poisoning of iron and calcium on yin and yang resins

[0006] 4. Silicon pollution, the efficiency of removing silicon from the anion resin is reduced, and there is a phenomenon of continuous release of silicon during operation. These colloidal silicon compounds block the exchange channels in the resin and reduce the exchange capacity.

[0009] (1) The discharge liquid seriously pollutes the environment;

[0010] (2) Ferric ions cannot be removed on the exchange group;

[0011] (3) For resins polluted by coagulants of linear structure, recovery with hydrochloric acid alone is ineffective;

[0012] (4) Serious damage to the anti-corrosion layer of the softened water system;

[0013] (5) The recovery effect is low, and the resin after recovery can only increase the industrial delivery capacity by about 5% compared with before recovery;

[0014] (6) Static immersion, uneven recovery of resin, long recovery time, uneven medicament

[0018] (3) The removal rate of organic matter is low, which can only reach 50-60%;

[0019] (4) Serious damage to the anti-corrosion layer of the softened water system;

[0020] (5) Soaking recovery time is long, the medicine is uneven, and the effect is very poor;
