Mixed bed recovered acid and alkali liquid preparing system

Abstract

The invention relates to a mixed bed recovered acid and alkali liquid preparing system which comprises an acid measuring tank, an alkali measuring tank, a first sprayer, a second sprayer and a hydrochloric acid pipe, wherein a demineralized water pipe is connected with a first sprayer inlet and a second sprayer inlet. The mixed bed recovered acid and alkali liquid preparing system is characterized by being provided with a hydrochloric acid pipe, a sodium hydroxide pipe, an industrial water pipe and an acid mist absorber, wherein the hydrochloric acid pipe is connected with an acid inlet of the acid measuring tank, the acid measuring tank is connected with the acid mist absorber and an acid discharging pipe, an acid outlet of the acid measuring tank is connected with an acid liquid inlet of the first sprayer, the sodium hydroxide pipe is connected with an alkali inlet of the alkali measuring tank, the alkali measuring tank is provided with an alkali discharging pipe, an alkali outlet of the alkali measuring tank is connected with an alkali liquid inlet of the second sprayer, the industrial water pipe is connected with the acid mist absorber, a second branch pipe of the water pipe is connected with a first branch pipe of the water pipe and an acid tank water inlet, and the first branch pipe of the water pipe is connected with an alkali tank water inlet. The mixed bed recovered acid and alkali liquid preparing system is high in regeneration efficiency and the operation difficulty is lowered.

Description

technical field [0001] The invention relates to a mixed-bed regenerating acid-base solution preparation system. Background technique [0002] Mixed bed refers to the system equipped with hydrogen type cation exchange resin and hydroxide type anion exchange resin. Hydrogen-type cation resins are used to remove cations in water; hydroxide-type anion resins are used to remove anions in water. H in water after mixed ion exchange ＋ and OH － Immediately generate water molecules with a very low degree of ionization, and are less likely to form counter ions during cation or anion exchange, which can make the exchange reaction very thorough, and the effluent water quality is excellent. The mixed bed is generally placed after the electrodialyzer or reverse osmosis device ( Or directly applied to water with low salt content), further desalination of water can produce higher pure water (conductivity≤0.2μs / cm), which is widely used in electronics, chemical industry, medicine, atomic e...
