Product Description

Multi-column automatic backwash filter:

Multi-column automatic backwash filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, urban water supply fields, such as industrial condensate water, washing water, wastewater, circulating water filtration, metallurgical industry connection Casting water system, blast furnace water system, high-pressure water dephosphorization water system for hot rolling, is an advanced, efficient and easy-to-operate automatic filter device.

The multi-column automatic backwashing filter developed by our company is composed of a housing, filter elements, backwashing rotating mechanism, differential pressure controller and electronic control part.


Working principle:

The filter element adopts a high-strength Johnson mold filter mesh or a metal woven mesh filter element, and the filter element is automatically cleaned through pressure difference control and timing control. When impurities in the filter accumulate on the inner surface of the filter element and cause the pressure difference between the inlet and outlet to increase to the set value (such as: lkgf/cm2), or the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism. When the backwash suction cup port is directly opposite to the filter element inlet, the blowdown valve is opened, and the system discharges pressure at this time. A negative pressure zone appears on the inside of the suction cup and the filter element whose relative pressure is lower than the water pressure outside the filter element (backwash pressure difference). Controlled at 3-4 times of the filter pressure difference), forcing part of the net circulating water from the outside of the filter element to flow into the inside 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 drain valve.


The Features of water filter housing

1. Microcomputer program control: automatic filtration, automatic identification of pressure difference, automatic backwashing, automatic drainage, low operating cost;

2. Uninterrupted continuous work: clean the filter element one by one, and filter uninterrupted;

3. High efficiency and low energy consumption: large effective filter area, low backwash frequency, small sewage volume, low system resistance loss;

4. Good backwashing effect: the unique filter structure and cleaning control method make the backwashing intensity high and clean thoroughly;

5. Wide range of application: the accuracy covers 10-3000 microns.

Remarks: 1. The above working pressure is less than 1.0MPa, the working temperature is 10-80℃, the filter medium is a non-toxic liquid, the filter screen is 304, and the rest are carbon steel.
2. The control cabinet is an ordinary control cabinet. If it is a domestic PLC text screen control cabinet, the cost will be calculated separately, and if it is a domestic PLC touch screen control cabinet, the cost will be calculated separately.
3. The above legs are made of carbon steel. For shells with diameters of 273~600, if the legs are made of stainless steel, the cost will be calculated separately. For shells with diameters of 600~1200, the cost of the legs will be calculated separately

Application areas:

Metallurgical industry: filter the particulate impurities in the water system such as heavy metal waste cleaning and recycling washing water, cooling circulating water, cold suspected water, etc., to protect nozzles and water pumps, to ensure the high quality of products and the long-term stable operation of the system.

Chemical industry, petrochemical industry: filter the impurity particles in brine, industrial water, and circulating cooling water system to purify chemical media and improve product quality.

Power plants, thermal power plants: filter the impurity particles in the wet electric precipitator spray, spray circulating gray water, condensate water, and desulfurization wastewater systems to purify water quality, protect nozzles and water pumps, and ensure long-term stable operation of the system.

Oilfield sewage: filter suspended solids in oilfield sewage to ensure the quality of recharge water
