Problems solved by technology

Because these filter elements are not cleaned in time, the filter elements are blocked, and the filter elements are replaced directly, resulting in a lot of waste of filter elements and increasing the cost of users. At the same time, a large number of replaced filter elements also cause new pollution.

Embodiment 1

[0029] Such as figure 1 As shown, an intelligent self-cleaning system for commercial water purifiers, including control system 1, backwash system 2 and bipolar membrane acid-base regeneration system 3; PP cotton filter unit 4 in commercial water purifiers, pre-activated carbon Filter element unit 5, ultrafiltration membrane unit 6, RO reverse osmosis unit 7, rear activated carbon filter element unit 8 are equipped with pressure sensors at the inlet and outlet, the pressure sensors are connected to the control system, and the control system can receive the pressure changes of each unit in real time; The PP cotton filter element unit, pre-activated carbon filter element unit, ultrafiltration membrane unit, RO reverse osmosis unit, and post-position activated carbon filter element unit in the water tank are equipped with flowmeters, which are connected to the control system. The control system can control the flow of each unit in real time. flow rate; the inside of the commercial...

Embodiment 2

[0036] The intelligent self-cleaning process for the commercial water purifier of the present embodiment is as follows:

[0037] The tap water first passes through the flowmeter to the PP cotton filter element, and the flow rate is controlled at 10 L / min. After being intercepted by the PP cotton filter element, it can remove large particles of impurities and suspended solids in the water. After being filtered by the PP cotton filter element, the water enters the pre-activated carbon filter element, and the flow rate is controlled at 10 L / min. The activated carbon is activated carbon prepared from coconut shells. The average particle size should be 1.5mm and the effective particle size should be 0.8mm. After being adsorbed by pre-activated carbon, the water enters the ultrafiltration unit, the flow rate is controlled at 10 L / min, and the ultrafiltration membrane controls the ratio of product water to return water at 1. After being filtered by the ultrafiltration membrane, the w...

Embodiment 3

[0039] The intelligent self-cleaning process for the commercial water purifier of the present embodiment is as follows:

[0040] The tap water first passes through the flow meter to the PP cotton filter element, and the flow rate is controlled at 15 L / min. After being intercepted by the PP cotton filter element, it can remove large particles of impurities and suspended solids in the water. After being filtered by the PP cotton filter element, the water enters the pre-activated carbon filter element, and the flow rate is controlled at 15 L / min. The activated carbon is activated carbon prepared from coconut shells. The average particle size should be 1.5mm and the effective particle size should be 0.8mm. After being adsorbed by pre-activated carbon, the water enters the ultrafiltration unit, the flow rate is controlled at 15 L / min, and the ultrafiltration membrane controls the ratio of product water to return water at 1. After being filtered by the ultrafiltration membrane, the ...

Abstract

The invention relates to an intelligent self-cleaning system for a commercial water purifier and a cleaning method. The intelligent self-cleaning system mainly comprises a set of complete cleaning system; the effluent index of the rear end of each step of a treatment process is monitored online in real time through a control system; and if the effluent index of the rear end of one step of the treatment process exceeds a set value, the control system can automatically clean a polluted unit. Through the control of the intelligent online self-cleaning system, efficient cleaning can be realized, the frequency of replacing a filter element of the commercial water purifier is greatly reduced, and the economic burden of a user is reduced. The invention provides an effective solution for self-cleaning of the commercial water purifier by adopting online monitoring, the intelligent self-cleaning system and the like.

Description

technical field [0001] The invention belongs to the technical field of self-cleaning of commercial water purifiers, and in particular relates to an intelligent self-cleaning system and cleaning method for commercial water purifiers. Background technique [0002] Water is the source of life. With the gradual improvement of people's living standards, the concept of safe and healthy drinking water continues to strengthen, and the demand for water purifiers is increasing. Water purifiers are also called water purifiers and water quality purifiers. Technology is a filter. According to different membrane structures, it is divided into ultrafiltration membrane and reverse osmosis membrane. Commercial water purifiers mainly use reverse osmosis membrane. Reverse osmosis membrane is the core component of water purifier. characteristic artificial semipermeable membrane. Generally made of polymer materials. Such as cellulose acetate film, aromatic polyhydrazide film, aromatic polyami...
