The principle and characteristic of horizontal automatic self-cleaning filter are introduced
Horizontal automatic self-cleaning filter is a kind of filter screen directly intercept impurities in the water, remove suspended matter, particulate matter, reduce turbidity, purify water quality, reduce system dirt, bacteria and algae, rust and other equipment to purify water and protect the normal work of other equipment system, water inlet into the self-cleaning filter body. Because of the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition, automatic blowdown valve signal. Realize fully automatic operation, no personnel care.
First, the working principle
Horizontal automatic self-cleaning filter: the water to be treated by the water inlet into the body, the impurities in the water deposited on the stainless steel screen, resulting in differential pressure. The pressure difference of inlet and outlet is monitored through the differential pressure switch. When the differential pressure reaches the set value, the electric control device gives the hydraulic control valve and the driving motor signals, which trigger the following actions: The motor drives the brush to rotate, cleaning the filter element, and the control valve is opened for sewage discharge. The whole cleaning process only lasts for dozens of seconds. When the cleaning is over, the control valve is closed, the motor stops rotating, the system returns to its initial state and begins to enter the next filtration process.
Second. Technical characteristics
1.Horizontal automatic self-cleaning filter design simple structure, small footprint;
2.Horizontal automatic self-cleaning filter reverse cleaning time is short, small pressure loss, less sewage consumption, not more than 1% of the total flow;
3.High filtration precision, suitable for all kinds of water quality;
4.Intelligent control system (PLC, PAC) control, high degree of automation, can realize remote control;
5.Equipped with motor overload protection, can protect the motor;
6.Cleaning sewage can not interrupt water supply, without bypass characteristics;
7.Strong maintainability, easy to install and disassemble;
8. The connection mode of the pipeline with the user is flange connection. The flange adopts the national standard flange with strong universality.
Third. Use
1.Metallurgy: continuous casting water, high pressure phosphorus removal water, clean ring water, turbidity ring water filtration, cooling water filter, by-filter, nozzle protection, etc.
2.Power: turbine cooling water filtration, gray water recovery filtration, dust removal nozzle protection, cooling tower water filter and by-filter, etc.
3.Widely used in drinking water treatment, building circulating water treatment, industrial circulating water treatment, sewage treatment, mining water treatment, golf course water treatment and other fields.
