Cooling water self-cleaning filter

1、 Product Overview:

Shenmai Industrial Fully Automatic Brush TypeCooling water self-cleaning filterCan be used inOn pipelines ranging from DN25 to DN900, self-cleaning filters have the characteristics of continuous flow, minimal maintenance, simple operation, and high flow rate, and are widely used in all industrial applications.Brush style self-cleaning filter cartridge available for selectionA wedge-shaped filter screen with a thickness of 5000um~50um can be used, and the filter material can be selected from 304, 304L, 2205, 2507, TA2, etc. The outer shell can be made of carbon steel, stainless steel, or corrosion-resistant lining, or other customized materials.Brush type self-cleaning filters can be used for industrial circulating water filtration, central air conditioning cooling water filtration, sewage biochemical treatment pre filtrationRO system pretreatment, papermaking white water, filtration, metallurgical cooling circulating water filtration, agricultural irrigation, seawater desalination, rainwater collection, landfill leachate and other fields.

2、 Working principle:

When the water that needs to be filtered enters through the inletCooling water self-cleaning filterInside the filter cartridge, impurities are intercepted inside the filter element. After filtration, clean water flows out from the outlet. As the filtration time increases, the impurities inside the filter element accumulate more and more. When the pressure difference between the inlet and outlet of the filter reaches the set value (adjustable), the filter begins to automatically clean. The entire cleaning process consists of two steps: opening the filter Automatic drain valve, the motor drives the cleaning brush inside the filter element to perform axial cleaning of the filter element. Impurities are brushed off and discharged by the water flow towards the filter drain outlet. The entire cleaning process is uninterrupted, and the entire operation of the fully automatic brush self-cleaning filter is controlled by a randomly equipped intelligent control box. The control mode can be selected from differential pressure, time, manual orPLC control.

4、 Product features and advantages:

1. Continuous flow filtration: When cleaning, open the drain valve, and the amount of sewage is 5% of the filtered amount. The cleaning time is 15-60 seconds, and the inlet water flows normally without interruption.

2. Filtering accuracy: The accuracy is between 100um and 2000um.

3. Large effective filtration area: The standard selection filter screen has an effective filtration area that is more than 8 times the inlet area, and the filtration pressure drop is small.

4. Reliable cleaning: There are multiple control methods to choose from, including manual, differential pressure, time, PLC program, etc.

5. Simple installation form: There are various structural forms, including vertical, horizontal, Y-shaped, suitable for on-site installation of various pipeline conditions.

6. Long service life: Under normal circumstances, the designed service life is over 10 years, requiring only regular maintenance and low manual maintenance costs.

5、 Application scope:

1. Air conditioning and HVAC system: effectively reduces suspended solids and turbidity, solves system blockage problems such as condensers and coolers, and improves system operating efficiency;

2. Steel: used for water treatment filtration in raw material yards, sintering pellet plants, cooling water filtration in blast furnaces, rolling mills, continuous casting machines and other systems, and impurity filtration in high-pressure water phosphorus removal systems;

3. Automotive manufacturing: coating production lines, cooling circulating water systems, applied in water treatment processes for automobiles, tractors, motorcycles, and engine manufacturing;

4. Power plant: used for precision pretreatment of high-purity water preparation for power plant boilers, filtration of cooling circulating water and sealing water for generators;

5. Petrochemical industry: Performing side filtration treatment in circulating water plants, which can replace filter media filtration with single or multi machine parallel main treatment, reduce filter media filtration load, avoid a large amount of flushing water consumption, and save costs;

6. Agriculture, forestry, landscaping, and papermaking: In sprinkler and nozzle systems, it is necessary to reduce equipment blockage and wear caused by impurities, so high-precision and highly automated filtration products need to be selected;

7. Water supply and sewage treatment: used in pre-treatment systems to improve system operating efficiency;

8. Mining: Filter the underground sprinkler water to ensure the normal operation of the system;

9. Mechanical, food or other: Automatic precision filtration of the system to prevent blockage of the cooling water system.
