Double filter is also called double switch filter. It is made of two stainless steel filters in parallel. It has a novel and reasonable structure, good sealing, strong flow capacity, and easy operation. In particular, the side leakage rate of the filter bag is small, the accuracy of the filtration can be accurately ensured, and the filter bag can be quickly and easily replaced, and the filter basically has no material consumption, resulting in a reduction in the operating cost. Then, Xiaobian will introduce the principle of dual filter and the applicable range of dual filters.
Double filter principle
This equipment is all made of stainless steel. It is composed of two columns. It is a single-layer stainless steel welded structure. The inner and outer surfaces are polished, and the top is equipped with a bleeder valve, so that it can be used for deflation during work. The pipe joint adopts bulging connection. After the 0.3Mpa water pressure test, the three-way male screw cock has flexible opening and closing. The device has compact structure, convenient operation and simple maintenance.
Double filter is also called parallel switch filter. It uses two three-way ball valves to assemble two single-tube filters on a single stand. It does not need to stop when cleaning the filter to ensure continuous operation. It is a non-stop production line filter device. The filter element of this filter, in addition to the stainless steel filter element, can also be made of high-quality honeycomb-type debinding fiber cotton, which can filter out particles with a particle size of 1μ or more. The filter can also be used in a single cylinder. Common base, the remaining dimensions are unchanged.
The internal and external surfaces of the double filter are polished. The filter cartridge is equipped with a stainless steel filter and a filter support basket. The top is equipped with a bleeder valve to discharge the air in the filter during filtration. The upper cover and the filter cartridge are connected by a quick opening structure, which makes it easier to clean (replace) the filter screen. The three adjustable feet allow the filter to be placed on the ground smoothly. The connecting pipeline adopts live connection or clamp connection. The inlet and outlet valve adopts three-way ball valve to open and close. The pressure resistance and temperature resistance, the operation is flexible and convenient, and the liquid leakage is more hygienic.
Double filter application
1. Weak and corrosive materials in chemical and petrochemical production, such as: water, ammonia, oil products, hydrocarbons, etc.
2. Corrosive materials in chemical production, such as: caustic soda, concentrated sulfuric acid, carbonic acid, acetic acid, etc.
3, the cryogenic materials in the refrigeration, such as: liquid methane, liquid ammonia, liquid oxygen and various refrigerants.
4, light food, pharmaceutical production in the health requirements of the material, such as: beer, beverages, dairy products, food and pharmaceutical supplies.
Double filter installation
1. When installing and using, pay attention to the protection of the control box, sensor and transmission part to prevent damage
2. Connect the pipe in the direction of the arrow on the stainless steel self-cleaning filter body
3, when adjusting the electric part, please note that the direction of rotation of the motor should be consistent with the direction of the logo
4. The installation should be considered for ease of maintenance and bypass piping should be installed.
5, the installation should be considered as far as possible in the lower part of the sewage outlet, to facilitate the discharge of debris.
6, Sewage pipe received sewage drain, sewage pipeline should not be too long.
Editor's summary: The principle of double filters and the scope of application of dual filters are introduced here. We hope to help everyone. If you want to know more related information, you can pay attention to this website information.

Tempered Glass is one kind of safely glass being produced by heating flat glass to its softening point. Then on its surface forms the compressive stress and suddenly cool down the surface evenly, thus the compressive stress again distributes on glass surface while the tension stress exists at the center layer of the glass. The tension stress caused by outside pressure is counterbalanced with the strong compressive stress. As the result the safety performance of glass is increased.
