What are the applications of self-cleaning filters in different industries

Self-cleaning filter is widely used in the water treatment industry, and the filtering effect is generally recognized by the industry, but some customers do not know much about it, and they are not clear how it is. So, what are the applications of self-cleaning filters in different industries?

Self-cleaning filter is a fine equipment that uses the filter screen to directly block impurities in the water, remove suspended matter and particulate matter, reduce turbidity, purify water quality, reduce system fouling, bacteria and algae, rust and other attacks, so as to purify water quality and protect the normal operation of other equipment in the system. Water enters the self-cleaning filter body from the water inlet. Due to intelligent (PLC, PAC) planning, The system can actively identify the degree of accumulation of impurities and give the signal to the blowdown valve to actively blow down.

Self-cleaning filter cleaning features:

1. The bottom with a centrifugal plate, can make the water vortex, the formation of centrifugal force, so that solid particles away from the filter plate, gathered at the top of the filter, reduce the filter cleaning frequency. During backwashing, the four spray columns in the center of the filter element spray water tangentially to strike the platter and make the platter rotate, so that the dirt stuck on the platter generates centrifugal force and leaves the platter, which is convenient for cleaning and reduces the cleaning time.

2. The disc diameter is large, the same number of platters corresponding to the filter filter area is large, so as to increase the filtration capacity. The structure of the inner cavity conforms to the characteristics of hydraulics and has a streamlined structure, which can reduce the loss of water flow head and reduce energy consumption. Filter shell integral forming, processing technology, avoid all kinds of leakage caused by steel filter shell welding.

3. High strength ductile iron material corrosion resistance is better, prolong the service life of the product; Proprietary filter element design and manufacturing technology, high precision filter element wear; Reliable intelligent control, automatic operation of filtration, cleaning and sewage discharge, realize unguarded, uninterrupted water supply; Product structure and function design, compact structure, large filtration area, high amount of pollution, pipeline pressure loss is small, low power consumption; Optimized control mode design, short backwash time, less waste water consumption, save water resources; Product line covers various flow and precision range, a variety of structural forms, to adapt to the complex user conditions; The parameters can be adjusted according to the actual working conditions, simple operation, maintenance-free, long life. The cleaning method is simple, and the cleaning cycle is monitored electronically, which can realize automatic cleaning and blowdown.

4. All parameters in the control system can be adjusted. Equipped with motor overload protection, can effectively protect the motor. It has the characteristics of uninterrupted water supply and no bypass when cleaning sewage, and the cleaning time is short, the sewage consumption is less, the maintainability is strong, the installation and disassembly is simple and easy. The connection mode of the pipeline with the user is flange connection, the flange adopts the national standard flange, strong universality.

Industry application:

1. used in printing and dyeing textile industry: reduce chroma function

Dyeing textile sewage for colored sewage, in the filtration process to decolorization of water, the filter has ray light function, through the vision into kinetic energy, emit rays, decolorization of water, with the performance of desalination chroma. Secondly, printing and dyeing textile water contains a large number of fiber impurities, easy to block the filter screen, and the self-cleaning filter uses the fiber screen, fiber screen is composed of countless fine stainless steel wire, when the sewage with fiber impurities flows through the ordinary coarse filter, filter, the large fiber impurities interception. In turn, the water flows through a fine strainer, which uses a fiber mesh to effectively trap fine fiber impurities in the water.

2. used in oil and other oil filtration industry: intercept fiber impurity function

In oil filtration, the filter mainly plays the role of oil and water separation. In this separation method, the solid material is filtered out first, and the solid material is collected into a special container to recover the solid material. After filtering the solid material, the oil-water mixture is transferred to a high-power separator. Under conditions of pressure and temperature monitoring, the oil-water mixture is fed from bottom to top in a specified number of pipes. A combination of factors, such as kinetic energy of the liquid, temperature drop, and crystal nucleus formation, results in the separation of oil and water droplets: oil adheres to the walls of the container, while water is in the middle of the container.

3. Used in chemical industry: self-cleaning and disinfection function

The sewage discharged by chemical industry is characterized by toxic sewage, which will affect the environment if discharged directly. The equipment has a function, can improve the chemical industry discharge of toxic sewage, this function is UV self-cleaning and disinfection function. Self-cleaning disinfection makes the filtered water meet the national requirements for domestic water use. No need to use pharmaceutical, pure physical disinfection method, using micro electrolyte junction ultraviolet disinfection method, green environmental protection, harmless to human body.

The above is a simple description of the application of self-cleaning filters in different industries.
