Hello! The security filter and the terminal burner filter are both types of network filters, but their functions and functions are slightly different. A security filter is usually a network security device that is used to protect a network from a variety of cyber attacks and threats.

It can detect and filter network traffic to prevent malicious attacks, viruses, and malware from entering the network. Security filters are typically deployed at the edge of the network or at the nexus of the network and are characterized by high performance, high ampire, and high reliability. A terminal filter usually refers to software or an application that runs on an end device to filter and manage network traffic on an end device.

It can block various threats and interference to end devices such as ads, tracking, and malware, and provide personal privacy protection and network security protection functions. Terminal filters can be deployed on PCs, mobile phones, tablets, and other terminal devices. The difference between a security filter and a terminal filter is that the former is a network security device that is used to protect network security; The latter is software or application on the end device that is used to protect the privacy of the end device and the user.

The composition of the security filter:

Security filters.

Security filter, also known as cartridge filter and precision filter, is composed of two parts: filter cartridge and filter element. The filter cartridge of the security filter is generally made of stainless steel, and the filter material element of the security filter is:

Filter cloth, filter screen, filter sheet, sintered filter tube, wirewound filter element, meltblown filter element, microporous filter element and multi-functional filter element, etc.

How the security filter works:

The pores of the PP filter element are used to filter the trace suspended particles, colloids, microorganisms, etc. remaining in the water, which are intercepted or adsorbed on the surface and pores of the filter element. Under the action of pressure, the original liquid passes through the filter material, the filter residue remains on the filter material, and the filtrate flows out through the filter material, which can effectively remove impurities, sediments, suspended solids and bacteria in the water, so as to achieve the purpose of filtration. With the increase of water production time, the operating resistance of the filter element gradually rises due to the pollution of the retentate, and when the water pressure difference between the inlet and outlet reaches the operation, maintenance operations such as replacing the filter element should be carried out.

Security filter configuration structureStainless steel parts, with reference to GB150-1998 steel pressure vessel design, equipped with sanitary stainless steel pipe fittings and IS02852 standard quick-opening clamp or (GB HG) standard flange interface, stainless steel inner and outer surface mechanical polishing or internal coating PTFE; The polypropylene filter is designed and manufactured according to the HG T20640-97 standard and the Q 320585FHCO3-200 standard. It is matched with various types of filter elements, and pays attention to the installation and sealing design of the filter and the filter element; The filter is 100% tested for pressure resistance and tightness of water or air pressure; The design structure is reasonable, and the production meets the requirements of GMP specifications in the pharmaceutical industry; Configure Y-60 conventional, stainless steel, diaphragm pressure gauge as required.

Security filter principleThe shell of the security filter cylinder is generally made of stainless steel, and the tubular filter elements such as PP meltblown, wirewound, folded, titanium filter element, activated carbon filter element are used as filter elements, and different filter elements are selected according to different filter media and design processes to meet the requirements of effluent water quality. Under the action of pressure, the original liquid passes through the filter material, the filter residue remains on the pipe wall, and the filtrate flows out through the filter material, so as to achieve the purpose of filtration.

Under the action of pressure, the original liquid can pass through the filter material, the filter residue will remain on the pipe wall, and the filtrate will flow out through the filter material, which can achieve the purpose of filtration.

The structure of the filter: filter cloth, filter screen, filter sheet, sintered filter tube, wire-wound filter element, meltblown filter element, etc., should be different for the filter material, and the pore size of the filtration is also different. The security filter is a kind of filtration device between sand filtration and ultrafiltration, and the pore size of the filtration is between the ranges.

The same form of filter media can be divided into different specifications according to the external size. The wirewound filter element, also known as the honeycomb filter element, can be divided into two types: one is polypropylene fiber - polypropylene skeleton filter element, the highest service temperature is 60 degrees Celsius, and the other is absorbent cotton fiber - stainless steel skeleton filter element, the highest use temperature is 120 degrees Celsius.

The meltblown filter element is made of polypropylene as raw material, it uses the meltblown process to form the filter material, the maximum temperature is 60 degrees Celsius, and the security filter can remove suspended solids and some colloidal substances and small particles in the water quality.

The shell of the stainless steel security filter is made of high-quality stainless steel, and the filter element is made of molded filter material polypropylene fiber meltblown, under the action of pressure, the original liquid passes through the filter material, the filter residue is left on the filter material, and the filtrate flows out through the filter material, which can effectively remove impurities, sediment and suspended solids and bacteria in the water, so as to achieve the purpose of filtration.

The inlet and outlet water of the security filter shall be equipped with a nuclear pulse pressure gauge; Change to Weixiang.

When the pressure difference between the inlet and outlet water reaches the limit value during operation, the filter element should be replaced in time; Mountain staring.

Due to the low efficiency of cleaning and recovery of the filter, it is recommended to use a disposable filter.

When there is a significant drop in pressure or flow rate between the upstream and downstream of the filter, a replacement of the filter element should be considered.

Security filter is a device often used in industrial filtration, especially in industrial water treatment systems, which are used in front-end filtration and mid-end filtration.

Use security filters.

It should be operated in accordance with the provisions of the technical manual so as not to affect or reduce the service life of the filter. In particular, some precautions for use need to be understood in advance.

Precautions for the use of security filters:

In order to ensure the filtration effect as much as possible, improve the efficiency of electronic sewage treatment. When purchasing a security filter, you can choose a filter that is twice the actual water production, which can reduce the frequency of filter bag replacement.

2.When operating, it is necessary to use the hand bridge according to the quota, voltage, or frequency indicated on the sign.

3.Do not use if you experience damage to the filter, especially if the power cord is damaged.

4.It is necessary to ensure that the filter is working at the correct water level, and the high-flow bag filter should not be used without water.

5.Make sure that the cord plug is not wet and that the plug must be scrubbed clean before reconnecting the power supply.

6.The interface size of the security filter should be consistent with the size of the pipe connection, and its size should be configured according to the requirements of the equipment.

7.After a certain period of time, the equipment needs to be maintained, cleaned and maintained, and before cleaning, be sure to disconnect the power supply of the filter.
