Description
Technical Field
The utility model belongs to the technical field of application of ion exchange resin for chemical desalination of water treatment, and relates to an automatic pretreatment device for ion exchange resin.
Background
The ion exchange desalting technology removes impurity ions in water by means of exchange reaction of ions on an ion exchanger and ions in the water, so that qualified desalted water is obtained and is widely applied to water treatment processes of various industries. Ion exchange resins are among the most commonly used ion exchangers, and their performance and mode of use directly affect the quality of the chemically desalted effluent. Newly produced resins often contain small amounts of oligomers and monomers that do not participate in the polymerization or condensation reaction, which can migrate into solution when the resin comes into contact with water, acids, bases, or other solutions, affecting the quality of the effluent. In addition, the resin also contains inorganic impurities such as iron, lead, copper, and the like. Therefore, the new resin should be pretreated before use to remove soluble impurities in the resin, so as to not only improve the stability of the resin, but also activate the resin and improve the working exchange capacity of the resin.
The pretreatment method of the ion exchange resin is generally to alternately soak the resin in a hydrochloric acid solution or a sodium hydroxide solution with certain concentration and volume. The pretreatment process is generally performed manually by a worker, and includes the steps of preparing a hydrochloric acid solution or a sodium hydroxide solution, immersing the resin in the solution, stirring the solution, washing the resin, discharging waste liquid, and the like. The concentration of the hydrochloric acid solution for pretreatment is usually 5%, the concentration of the sodium hydroxide solution is usually 2% -4%, the problems of acid solution or alkali solution splashing, medicament volatilization, harm to body health and the like exist in the processes of preparing acid and alkali solutions and subsequent soaking and stirring by workers, the discharge, collection and treatment of the soaked waste liquid are carried out manually, and the risk of contact between the workers and dangerous chemicals is increased. If a resin pretreatment device can be constructed, the device can automatically prepare solution, automatically soak and wash resin and automatically collect pretreatment waste liquid, the whole pretreatment process does not need manual contact of acid liquor and alkali liquor, the problems can be better solved, but similar disclosures are not available in the prior art.
