Product introductionLCD
Series multi-column automatic backwash filter is widely used in coal-to-gas, metallurgy, chemical, petroleum, papermaking, medicine, food, mining, electric power, urban water supply fields. Such as industrial condensate, washing water, wastewater, circulating water filtration, metallurgical industry continuous casting water system, blast furnace water system, hot rolling high-pressure water descaling system is an advanced, efficient and easy-to-operate automatic filtration device

Working principleThe
LCD series multi-column automatic backwash filter produced and developed by our company is composed of a shell, a filter element, a backwash rotating mechanism, a differential pressure controller and an electronic control part.
The filter element adopts a high-strength Johnson wedge-shaped filter or a metal braided mesh filter element, and the filter element is automatically cleaned through differential pressure control and timing control. When impurities accumulate on the inner surface of the filter element and cause the inlet and outlet pressure difference to increase to the set value (e.g., 1kgf/cm2), or when the timer reaches the preset time, the electric control box sends a signal to drive the backwashing mechanism. When the backwash suction cup mouth and the filter inlet are facing each other, the blowdown valve is opened, at this time, the system is depressurized and drained, and a negative pressure area with a relative pressure lower than the water pressure on the outside of the filter element appears on the inside of the suction cup and the filter element (the backwash pressure difference is controlled at 3~4 times of the filter pressure difference value), forcing part of the net circulating water to flow into the inner side of the filter element from the outside of the filter element, and the impurity particles adsorbed on the inner wall of the filter element enter the disc with the water flow and are discharged from the sewage valve.

Fields of application

The metallurgical industry
filters particles and impurities in the water system such as heavy metal waste cleaning and recovery washing water, cooling circulating water, condensate water, etc., protects the nozzles and water pumps, and ensures the high quality of the products and the long-term stable operation of the system.

Oilfield sewage filters suspended solids in oilfield sewage
to ensure the quality of recharge water.

Chemical and petrochemical
filter impurities in the brine and industrial water circulating cooling water systems, purify chemical media, and improve product quality.

Power plants and thermal power plants
filter impurities in the wet electrostatic precipitator spray, spray circulating gray water, condensate water, and desulfurization wastewater systems, purify water quality protection nozzles and pumps, and ensure the long-term stable operation of the system.
