Filter element with double filter layers and application thereof

Abstract

The invention discloses a filter element with double filter layers and application thereof. The filter element comprises an outer filter layer, an inner filter layer, a non-woven filter and protection layer, a water outlet cavity, round end covers at both ends and leakage-proof washers at both ends, wherein the inner filter layer is wrapped with the non-woven filter and protection layer to prevent granular active carbon filtering material from leaking; and both ends of the filter element are provided with two round end covers and two leakage-proof washers. The invention has the advantages that the assimilative capacity of the outer filter layer is enhanced, and the inner filter layer is effectively protected; the filter service life is prolonged by multiple times; the filter element has special effect on the deep purification of mineral water and drinking tap water and meets the demands for health drinking water of wide families, offices, schools and dining halls; and all materials and parts of the filter element can be recycled.

Description

【Technical field】 [0001] The invention relates to the technical field of drinking water treatment, in particular to a filter element with double filter layers and its application. 【Background technique】 [0002] With the continuous progress of social economy and production development and the people's increasing demand for material life and ecological environmental protection and health, people's requirements for drinking healthy and clean water are also getting higher and higher. Water is the source of life for all things. Life is inseparable from water. A person's life begins with water and ends with water. People drink clean and healthy water, which determines the health and longevity of the human body. However, due to the severe pollution of water quality in our actual ecological environment civilization, the natural civilization of water ecology and the water ecological environment have suffered increasingly serious damage. It is urgent to protect the ecological safety ...

However, due to the severe pollution of water quality in our actual ecological environment civilization, the natural civilization of water ecology and the water ecological environment have suffered increasingly serious damage. It is urgent to protect the ecological safety of drinking water. In real life, many civilian waste water , Industrial waste water, toxic and harmful waste water flows into rivers, lakes and seas, seriously polluting the water ecological environment and the water quality of rivers, causing large-scale pollution of lakes, making the water sources that people rely on for survival gradually turn black and smelly, seriously affecting people's drinking water health , Drinking unhealthy water for a long time will cause various diseases in the human body. In the schistosomiasis-infected area, people who come into contact with unclean water are easily infected with schistosomiasis, which is difficult to cure for life. Many different models appearing on the market and have Water purifier filter products with a certain water purification function are basically only products with deep water purification effects. Some deeply purified water will become acidic drinking water due to the chemical reaction of the reverse osmosis membrane. Long-term use will affect the human body. It is healthy, and the replacement filter element is expensive. Some filter elements will pollute drinking water many times. Some bottled water on the market also contains trace harmful elements bromate (carcinogen), especially some power-consuming water purifier products. It not only wastes energy, but also brings hidden dangers to family safety. Most of its water purifiers only consider their commercial values ​​and pursue selling points. The effect is not ideal, the service life is short, and the cost performance and practical effect of the filter element are low, which hinders the social, environmental protection, health and general practical effects of social and family applications and development of water purifiers.
