According to the grade of pipeline design, water purifiers can be divided into two categories: progressive water purifier and self-cleaning water purifier. The traditional water purifier is a progressive water purifier. Its internal pipeline is designed to be loose before and tight after the filter element. It consists of PP melt blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post activated carbon. Generally, the five stages are connected in turn. The retained material deposits in the filter core, which requires regular manual removal and washing to ensure the normal operation of the machine. The other is the more advanced self-cleaning water purifier.
Two channels are designed in the machine, and a washing water channel is added. As the washing water of ordinary domestic water passes through the channel, it scours the raw water side of the filter element in the machine, especially the membrane filter element, to achieve self-cleaning effect. The sewage will be intercepted by the water flowing from the head and tail at the instant of switching on and closing the washing faucet. Timely and fast discharge, the structure design is reasonable, the trouble of manual cleaning is saved, the re-pollution of the mechanism itself is avoided, and the cost of energy consumption is reduced at the same time. Self-cleaning water purifier adopts the new principle of mass distribution, impurities are cleaned out at any time, the inner core is clean, and secondary pollution is avoided. See the working principle below for details.
But please recognize that the self-cleaning water purifier is different from the automatic sewage purifier, the computer automatic flushing water purifier and the automatic backwashing water purifier seen on the market. The former is the whole machine self-cleaning, that is to say, all the filter elements inside the machine have a certain self-cleaning function; the latter only flushes one filter element rather than the whole machine. Popularly speaking, self-cleaning water purifier is equivalent to installing a garbage disposal unit in the pipeline, and the dirt is cleaned out at any time, not staying in the aircraft. The traditional non-self-cleaning water purifier is equivalent to a number of garbage cans in the room. The dirt is usually temporarily stored in the machine. Therefore, regular sewage discharge, cleaning and frequent replacement of filter elements are required.
Intelligent water purifier
It refers to the water purifier equipped with LED display screen, with voice function, temperature monitoring control, temperature alarm, water level control, water level monitoring alarm and other functions.
