Bag filter is a pressure type filter device, which mainly consists of a housing body, a housing head cover and a quick opening mechanism, and a metal reinforcement inner net.

The filtration liquid flows into the filter bag from the side inlet of the filter housing. The filter bag itself installs in the reinforced basket. The liquid is permeated through the filter bag of different pore size to obtain a qualified filtrate, and the impurity particles intercept by the filter bag.

Bag filter has many Features such as reasonable structure, good sealing, strong circulation, and easy operation. In particular, the side leakage rate of the filter bag is small, the filtration accuracy can be correctly ensured, and the filter bag can be quickly changed, and no material consumption, so that the operation cost is lowered.

The inner and outer surfaces of the filter can be mechanically blasted or polished to remove surface oxide scales, burrs, etc. of mechanical equipment or parts, and have the effects of enhancing surface stress and matte effect.

The filtering is side entry and side-out way, or a side entry and bottom-out method, and the filtering liquid medium is pressed or drawn into the bag filter barrel through the pressure in the pipe, which filtering is performed. The liquid medium is filtered by the filter bag supported by the filter basket and intercepted by the filter bag, and then released from the outlet of the filter. The inlet and outlet design of the bag filter generally adopts a side-entry and bottom-out mode for easy cleaning.

Product advantages

1. Large flow: The power adopts a unique horizontal discount design, which can effectively filter the power, and has a strong flow rate, so that the flow rate of the supporting power is as high as 20T/H, which increases the flow requirement that can be met by the intelligent power.

2. Compact structure: The use of fewer filter elements can reduce the size of the filter, which solves the problems of high investment cost, long replacement time, and troublesome operation of traditional filters.

　　3. Strong dirt holding capacity: The unique deep mesh structure of the high-flow filter element enables the filter element to have a higher slag holding capacity, and can better remove suspended solids and particles in the water.

　　4. Easy to use: The design of the large-flow filter system adheres to the concept of easy installation and replacement. The design of the installation handle at the end of the filter element conforms to the principles of ergonomics, ensuring that the installation and removal of the filter element is simple and convenient without the need for additional special tools;

　　 5. Wide range of applications: It is often used in ultrafiltration, reverse osmosis, ion exchange, precision filtration before electrodialysis, and is also an ideal equipment for purification of various liquids.

 

precision membrane filter shell material is commonly, stainless steel. Filter mainly adopts the folding membrane filter ( Hyperlink) 。 High filtration precision, big filter area, no residual liquid and low operating differential pressure. Filter material in accordance with the FDA and GMP requirements, which are widely used in food, pharmaceutical, electronics, ultrapure water purification.

The performance of the PP pleated filter element microfiltration membrane needs to be measured. The measurement method mainly starts from four aspects, which are membrane defects, membrane thickness, membrane apparent density and porosity. 1. Determination of membrane defects. Film defect refers to the existence of holes in the surface or deep layer of the film, and their existence has a direct impact on the performance of the film. Therefore, the defective film should be removed before use. Defective membranes can generally be inspected visually or with the aid of a microscope, and can also be determined by bubbling by immersing them in water (or in the non-solvent of the membrane). 2. Measurement of film thickness. Generally, a spiral micrometer or thickness gauge is used for measurement, and it can also be measured visually under a microscope or electron microscope. 3. Determination of apparent density of film. Generally, a weighing method is used to first weigh the mass of the film, and then calculate the volume based on the measured film thickness and inner and outer diameter data. The ratio of the two is considered to be the apparent density of the film. 4. Determination of porosity.

At present, there are many types of ultrafiltration membrane water purifiers on the market with different filtration methods. In the process of use, the filter element needs to be replaced regularly, and how to choose the ultrafiltration membrane filter element has also become a difficult problem for everyone. Ultrafiltration membrane filter element selection First of all, you need to know the replacement cycle of filter element replacement. The ultrafiltration membrane cartridge is a consumable item. However, the longer the ultrafiltration membrane filter element is used, the better, because the change of the water quality of the effluent cannot be observed with the naked eye, and the service life will have a great relationship with the water quality and water pressure of the raw water. When the water volume of the effluent drops significantly, it indicates that the filter element is seriously blocked, and the filter element needs to be replaced when the time is not enough. Secondly, everyone needs to understand that there are three types of ultrafiltration membrane water purifiers commonly used in the market: multi-stage filtration water purifiers, central water purifiers, and stainless steel water purifiers. The ultrafiltration membrane filter element in the multi-stage filtration water purifier generally adopts external pressure filtration, such as shortcut filter element, easy-insertion filter element, lock-tooth filter element and so on. And which filter element is needed for the water purifier used, you can compare the appearance and size of the product sample, and then confirm the filter element you need. Finally, it is necessary to carefully understand the quality of the filter element, which must be observed from the material, shell, appearance and other aspects of the product. 1. The filter element membrane wire material, generally household PAN polypropylene cyanide and alloy PVC polyvinyl chloride are better, hydrophilic material, not easy to block, and the material itself does not cause any harm to the human body. 2. The material of the filter element shell, the water filtered by the filter element of the water purifier is directly consumed or used, and the water quality of the effluent is relatively high. Therefore, the shell material requirements of the filter element are also relatively high, and food-grade materials are used, such as food-grade ABS, UPVC and other materials. 3. The quality of the membrane filament, whether the pore diameter of the membrane filament is uniform, whether the wall thickness is uniform, whether there is eccentricity, etc., the outer diameter of the hollow fiber ultrafiltration membrane: 0.5-2.0mm, the inner diameter: 0.3-1.4mm. 4. The filtration precision of the membrane wire will directly determine the quality of the effluent. The filtration precision of the filter element of the household ultrafiltration membrane water purifier is 10nm. 5. On the end face, whether the membrane filament is fully filled, and whether the position is evenly distributed and centered. The fullness of the membrane filaments can ensure the water volume of the effluent; the distribution of the membrane filaments is evenly centered, so that the force of the membrane filaments is uniform, and it is not easy to cause the membrane filaments to break, ensuring the service life of the filter element. 6. Is there a lot of membrane wire plugging holes on the end face, too many plugging holes at both ends will affect the water output, and too many plugging holes at one end will form blind holes, which will affect the water output or flushing effect. According to the specific situation, choose a suitable ultrafiltration membrane filter element to make the filtered water clearer and with high precision.
