Air FilterWhat are the performance aspects of the What are the common types of industrial filter equipment?

Many consumers have chosen to buy in order to protect their health.Air FilterBut most consumers are not very familiar with the performance of air filters, so in the process of using a lot of trouble, the following I explain the four aspects of the air filter performance introduction:

I. Filtration principle

1, interception: can also be called sieve, as long as it is larger than the sieve hole of the pollution particles will be intercepted, and then filtered out, smaller than the sieve hole of the particles will leak through.

2, collision: larger particles in the air will do with the airflow irregular movement, in the process and obstacles will collide with each other, sticky, after being filtered.

3, diffusion: smaller particles in the air to do irregular Brownian motion, in the process will also be and obstacles hit and then be filtered, which is also known as the diffusion mechanism.

II. Characteristics

1, filtration efficiency: according to "the amount of particles filtered out / the total amount of particles before filtration × 100%" such a formula to calculate the filtration efficiency.

2, the initial resistance: air movement around the fiber will produce a small resistance, so that the combination of countless tiny resistance is the filter media to the air resistance, resistance and the speed of the airflow is also relevant, the faster the resistance is greater.

3, dust capacity: a filter to reach the final resistance, the total amount of dust that can be accommodated on the filter media is the dust capacity of the equipment.

III. Filtration speed

Filtration speed refers to the speed of air passing through the filter media when it is perpendicular to the direction of the filter media, rather than the head wind speed of the filter. The faster the filtration speed, the greater the inertial force of the particles, the higher the efficiency of filtration for coarse and medium filters. But the same, the faster the speed of the air caused by the greater resistance, so the general coarse filter will keep the speed of 1 - 2 m / s, intermediate filters to keep at 0.2 - 1 m / s can be.

IV. Filter Media Composition

1, the filter media of the primary filter is mostly made of glass fiber, chemical fiber and non-woven fabric, which can be designed into plate type, folding type and bag type and so on.

2, medium-effect filter media generally use glass fiber, chemical fiber, non-woven fabrics, the general structure of the bag type, folding type.

3, high-efficiency filter media is mainly ultra-fine glass fiber, structure type is generally folded, divided into two kinds of partition and no partition.

Common types of industrial filter equipment

Industrial purification is an important step in China's sustainable development, many companies have been using filters for purification equipment, the following we will briefly understand the common types of commonly used industrial optical splitter:

Air Filter

This is the more common filter equipment and this equipment has important applications in industry. For one thing, air filters can be utilized to filter pollutants or particulate matter from air conditioning systems, making industrial environments cleaner. For another, air filters can also be used in large production plants to protect the health of workers.

High Temperature Resistant Filter

As the name suggests, this is filter equipment applied to industrial manufacturing. High temperature resistance is the basic requirement of many industrial production for equipment, such as the food industry, are generally treated with high temperatures, so when choosing purification equipment such as filters, will also favor high temperature resistant filters.

Chemical filters

This is targeted filter equipment, industry is not every kind of substance can be purified using the same filter equipment, so when you choose a filter, it must be based on the actual requirements. For substances that cannot be filtered but need to be processed, we can use chemical filters that utilize chemical reactions to purify pollutants, thus avoiding the production of harmful substances.

Stainless Steel Filter

This is a kind of filter equipment named according to the material, and many industries are now favoring this kind of filter equipment because of its higher durability and not easy to be damaged, so it is popular.
