Description

Technical Field

[0001] The utility model belongs to the technical field of filtration, and in particular relates to a double-drum filtration weak electrolytic water purification system. Background Art

[0002] Electrolyte water, also known as ionized water, refers to water that contains a certain amount of ions. These ions come from organic and inorganic substances in nature or from chemical improvers, and meet specific conditions so that the water has a benign charge distribution state and can complete the electrolysis reaction. It is an important special water used for industrial purposes and human drinking purposes. Weakly acidic electrolyzed water is electrolyzed water that controls the pH value and effective chlorine concentration by electrolyzing dilute hydrochloric acid. It has a high bactericidal effect and is colorless and odorless. It can be used as an insecticide solution or an industrial detergent to clean organic liquids and hydrocarbon surfaces.

[0003] At present, weak electrolytic solution uses a filtration device for purifying water quality during production. The existing filtration device is generally composed of two filters connected in series to form a relatively complete filtration and purification system. However, when the weak electrolytic solution passes into a single filter, the water flow has a strong pressure and causes an impact on the filter element. The continuous impact force can easily damage the filter element structure and affect the full filtering effect of impurities. In addition, the replacement of the internal filter elements of the two filters connected in series needs to be repeated, which makes the replacement work more cumbersome.

[0004] Therefore, a double-tube filtering weak electrolytic water purification system is needed to solve the problems in the prior art that when the weak electrolytic water passes through a single filter, the water flow has a strong pressure and causes impact on the filter element, and the operation of replacing the filter elements one by one is relatively cumbersome.
