A water purification device without a pre-filter element

Abstract

The invention provides a water purifying device without a front filter element. The water purifying device comprises a box type shell. A water inlet pipe, an ultrafiltration water outlet pipe and a purified water outlet pipe are arranged on the bottom plate of the shell. A membrane cavity, an ultraviolet sterilizer and a reverse osmosis filter system are sequentially arranged in the shell along the water flowing direction. A rotary ultrafiltration membrane rotary disc for performing ultrafiltration treatment on water entering the membrane cavity is arranged in the membrane cavity. The water inlet pipe is connected with the membrane cavity through a pipeline with a valve. The water outlet of the membrane cavity is connected with the ultraviolet sterilizer through a water outlet guide pipe. The water outlet of the ultraviolet sterilizer is connected with a three-way pipe. The first outlet end of the three-way pipe is connected with the reverse osmosis filter system through a pipeline, the second outlet end of the three-way pipe is connected with the ultrafiltration water outlet pipe through a pipeline with a first water outlet valve, and the water outlet of the reverse osmosis filter system is connected with the purified water outlet pipe through a pipeline with a second water outlet valve. The water purifying device has the advantages that the device combines the rotation cross-flow type membrane technology, ultraviolet sterilizing technology and the reverse osmosis technology, and high-turbidity water sources can be purified without the front filter element, a filter column and the like.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a water purification device without a pre-filter element. Background technique [0002] The safety of drinking water quality for rural people in my country has long existed, especially in some remote mountainous areas, old areas, and rural areas inhabited by ethnic minorities. Due to factors such as small water supply, scattered users, and terrain, it is impossible to implement centralized water supply. In addition, it is difficult to ensure the safety of drinking water in villa areas, sanatorium areas, expressway service areas, and field exploration, investigation, construction, camping, and disaster relief in the outer suburbs of the city, which are far away from the urban water supply system. For the above-mentioned areas where centralized water supply cannot be realized, it is necessary to purify rivers, lakes, ponds, groundwater, and accumulated rainwa...

AI Technical Summary

Problems solved by technology

This type of water purifier requires frequent replacement of the filter element, which is cumbersome, complicated, time-consuming to disassemble when replacing the filter element, and the replacement cycle is difficult to control. The pollution problem caused by the adsorption saturation penetration of the filter element and the growth of microorganisms is particularly prominent, which greatly limits its application.

In addition, since the filter-type water purifier is easily blocked by impurities such as suspended solids, it is difficult to apply to the direct purification of natural water source water, and basically can only be used for repurification of household tap water.

In vast remote areas such as rural areas and outer suburbs of cities and towns, for surface water, groundwater, brackish water, high-arsenic and high-fluorine water and other drinking water sources, the filter-type water purifiers currently on the market cannot be used stably for a long time
