Analysis of the working principle and characteristics of precision filtration devices
Analysis of the working principle and characteristics of precision filtration devicesAs we all know, precision filters have always been a very popular type of filtration device among all filtration devices, especially the word "precision" is a good expression of our performance summary of this device. If you also plan to purchase such a device, let's take a look at the working principle and characteristics of precision filtration devices with us!1. Working principle of the equipment The so-called precision filter design uses a molded filter material. Under the action of pressure, the liquid to be filtered passes through the filter material, leaving the impurities on the inner wall, and the clean filtrate flows out through the filter material, thereby achieving the purpose of filtration and purification. The molded filter materials generally used in the equipment include filter cloth, filter screen, filter disc, wire wound filter element, melt blown filter element, etc. Among them, the more commonly used wire wound filter element can be divided into two types: one is polypropylene fiber-polypropylene skeleton filter element, the highest use temperature is about 60℃; the other is absorbent cotton fiber-stainless steel skeleton filter element, the highest use temperature is about 120℃. The other melt-blown filter element is made of polypropylene as raw material and made by the melt-blowing process, and the highest working temperature is also about 60℃. 2. Technical parameters of the equipment 1. Material: 304, 316L stainless steel; 2. Number of filter elements: 1 core, 2 cores, 3 cores, etc.; 3. Length of filter element: single section, 2 sections, 3 sections, 4 sections; 4. Installation form: flat pressure type, snap-in type, and plug-in type; 5. Connection method: quick opening type, flange type; 6. Medium that can be filtered: liquid, gas. 3. Performance characteristics of the equipment 1. It has a very high filtering accuracy, and the pore size of the filter element is very uniform; 2. Ultra-small operating resistance, large flux, and long service life; 3. The cleanliness of raw materials is high and pollution-free; 4. Suitable for acidic and alkaline chemical solvent filtration; 5. The equipment has high processing intensity, and high-temperature resistance, and is not easy to deform; 6. Low cost and the filter element can be replaced. In this article, we start from the working principle and characteristics of the precision filtration device, and see the special features of this precision filter with you, which is also the reason why it is called "precision". I believe that after reading it, it will be very helpful for everyone's choice and use. |
