Description

Easy-to-maintain seawater electrolytic water generator {Apparatus for manufacturing ionic water} The present invention relates to an electrolytic water generating device that generates electrolytic water using seawater, and more specifically, to an easy-to-maintain electrolytic water generating device for seawater that facilitates maintenance by effectively removing sediment or minerals contained in seawater. An electrolytic water generator is a device that generates electrolytic water containing sodium hypochlorite, which has strong sterilizing power, by electrolyzing raw water containing brine. Since it can be produced in large quantities simply by applying power, it is used in places where there are many objects to be sterilized and cleaned. Meanwhile, seaweed farming refers to the artificial cultivation and reproduction of seaweed. Seaweed is cultivated by going through the seeding period around October when the seawater temperature is 23°C or lower, the germination period around November when the seawater temperature is 15–22°C, the thallus growth period around December–March when the seawater temperature is 5–8°C, and the breeding period around April–May when the seawater temperature is 12–23°C. The seeding period is the time when spores are collected on seaweed nets. In order to ensure successful seeding, the seaweed nets must be cleaned thoroughly, and the seaweed nets were mainly cleaned using a cleaning agent with a surfactant effect. The germination stage is the period when the neutral spores of laver grow into young leaves. Since green algae attach to the laver nets during this time and deplete nutrients, hindering the growth of the laver, green algae control agents are used to prevent their attachment. During the thallus growth stage, attention had to be paid to washing away mud or diatoms with a washing agent to promote the absorption of nutrients rather than removing green algae. In order to cultivate seaweed, fishermen must use washing agents or decontamination agents. However, in reality, it is difficult to manufacture and selectively use each agent according to its intended use. Therefore, for most of the cultivation period, they use only acid treatment agents containing hydrochloric acid to wash seaweed nets, decontaminate seaweed, or remove worms and diatoms from the seaweed nets. However, the use of acid treatment agents containing hydrochloric acid throughout the seaweed farming season is causing the surrounding ocean to be contaminated by the acid, leading to the death of marine life. Due to these problems, attempts are being made to replace acid treatment agents containing hydrochloric acid with electrolyzed water generated by the electrolysis of seawater. However, since seaweed farms are mainly located in areas where tidal differences occur due to high and low tides, the seawater used for electrolysis contains not only mineral elements such as potassium, calcium, and magnesium, but also sandy soil from tidal flats, and furthermore, various pollutants such as microplastics generated from various types of waste dumped into the ocean. Consequently, there was a problem in that during the process of electrolyzing seawater, sandy soil or pollutants were deposited on the inner surface of the electrolytic cell, contaminating the generated electrolytic water, and furthermore, a mineral layer formed on the electrode where electrolysis takes place, hindering the electrolysis of seawater, which reduced the productivity of the electrolytic water and shortened the lifespan of the electrode. Meanwhile, in seaweed processing plants that process fresh seaweed produced in seaweed farms into dried seaweed, there is a first process of washing the fresh seaweed using seawater and a second process of washing the fresh seaweed washed in the first process using a large amount of fresh water. Since the water used at this time is not sterilized or disinfected, various bacteria, such as E. coli, are detected in the washed fresh seaweed, and accordingly, a large amount of sterilized water is required to produce hygienic dried seaweed. However, large amounts of disinfectants must be added to use large quantities of water, but since these disinfectants are harmful to the human body, they do not serve as a suitable alternative.
