Q-0621-A|廣泛應(yīng)用|去離子
去離子發(fā)生器是一種用于去除水中離子雜質(zhì)的設(shè)備,主要通過(guò)兩種方式實(shí)現(xiàn):離子交換和電去離子。離子交換去離子是通過(guò)陽(yáng)離子交換樹脂和陰離子交換樹脂,將水中的陽(yáng)離子(如Na+)和陰離子(如Cl-)與樹脂上的H+和OH-進(jìn)行交換,生成水(H2O),從而達(dá)到去除水中鹽分的目的
電去離子(EDI)技術(shù)則是通過(guò)在淡水室中放置混合離子交換樹脂,利用電場(chǎng)作用,使陽(yáng)離子向陰極遷移并與樹脂上的OH-結(jié)合,陰離子向陽(yáng)極遷移并與樹脂上的H+結(jié)合,從而實(shí)現(xiàn)水的去離子化。這種方法不需要使用酸堿進(jìn)行再生,是一種更為環(huán)保的去離子技術(shù) 。
去離子水設(shè)備廣泛應(yīng)用于電子、電力、化工、電鍍、鍋爐補(bǔ)給水及醫(yī)藥等領(lǐng)域,特別是在制備超純水和高純水方面。隨著技術(shù)的發(fā)展,除了傳統(tǒng)的離子交換方法,還出現(xiàn)了結(jié)合反滲透(RO)、EDI等技術(shù)的去離子水制備工藝,這些工藝可以有效去除水中的離子,并降低運(yùn)行成本 。
此外,去離子發(fā)生器在空氣凈化領(lǐng)域也有應(yīng)用,如負(fù)離子發(fā)生器,它通過(guò)產(chǎn)生負(fù)離子來(lái)凈化空氣,提高空氣質(zhì)量。負(fù)離子發(fā)生器的工作原理是利用高壓電暈增加空氣中負(fù)離子的含量,從而改善空氣質(zhì)量,促進(jìn)身體健康 。負(fù)離子發(fā)生器可以促進(jìn)空氣中的氧分子激活,形成攜氧負(fù)離子,有助于除塵、滅菌和空氣凈化
A deionizer is a device used to remove ionic impurities from water, mainly through two ways: ion exchange and electric deionization. Ion exchange deionization is the exchange of cations (such as Na+) and anions (such as Cl-) in water with H+ and OH- on the resin through cation exchange resin and anion exchange resin to generate water (H2O), so as to achieve the purpose of removing salt from the water
Electrodeion (EDI) technology is to place a mixed ion exchange resin in the fresh water chamber, and use the electric field to make the cation migrate to the cathode and combine with OH- on the resin, and the anion migrate to the anode and combine with H+ on the resin, so as to achieve the deionization of water. This method does not require the use of acid and base for regeneration and is a more environmentally friendly deion technology.
Deionized water equipment is widely used in electronics, electric power, chemical industry, electroplating, boiler recharge water and medicine, especially in the preparation of ultra-pure water and high purity water. With the development of technology, in addition to traditional ion exchange methods, there have been deionized water preparation processes combined with reverse osmosis (RO), EDI and other technologies, which can effectively remove ions from water and reduce operating costs.
In addition, deionization generators also have applications in the field of air purification, such as negative ion generators, which purify the air by generating negative ions and improve air quality. The working principle of the negative ion generator is to use high voltage corona to increase the content of negative ions in the air, thereby improving air quality and promoting health. The negative ion generator can promote the activation of oxygen molecules in the air to form oxygen-carrying negative ions, which help to dust, sterilization and air purification
