Principles of Air Shower selection

Most of the earliest filtration was gravity filtration, later on, pressurized filtration was used to increase the filtration speed, and then vacuum filtration was introduced, and the invention of rotary drum vacuum filter at the beginning of the 20th century enabled continuous filtration. Since then, various types of continuous filters have appeared. Intermittently operated filters (plate and frame filter presses) were developed for automated operation, and the filtration area became larger and larger. To obtain a low moisture content of the filter residue, the Air Shower was developed as a mechanical press. Next, let's look at the principles of Air Shower selection. Here are some answers.

Here is the content list:

l Rational selection of the efficiency of the Air Shower.

l Correctly determine the dust content and particle characteristics of the outdoor air.

l Correct determination of the Air Shower characteristics.

l Analysis of the nature of the dust-containing gas.

Rational selection of the efficiency of the Air Shower.

According to the cleanliness and purification standards required in the room, the efficiency of the last stage of the air filter is determined, and the number of combined stages of the Air Shower and the efficiency of the various stages is selected rationally. If the room requires general purification, the primary filter can be used; if the room requires medium purification, the primary and intermediate filters should be used; if the room requires ultra-clean purification, the primary, intermediate, and high-efficiency filters should be used, and the efficiency of the filters at all levels should be matched reasonably and properly. If the difference in efficiency between two adjacent filters is too great, the first filter will not be able to protect the latter.

Correctly determine the dust content and particle characteristics of the outdoor air.

As the Air Shower filters and purifies the outdoor air before sending it indoors, the dust content of the outdoor air is a very important figure. Especially in multi-stage purification and filtration treatment, the choice of pre-filter should be decided after taking into account the usage environment, spare parts costs, operational energy consumption, maintenance, and supply.

Correct determination of the Air Shower characteristics.

The characteristics of the filter are mainly the filtration efficiency, resistance, penetration rate, dust capacity, filtration airspeed, and processing air volume. As far as possible, filters with high efficiency, low resistance, large dust capacity, moderate filtration airspeed, large processing air volume, easy manufacturing and installation, and low price should be used under the circumstances. This is necessary for the economic analysis of the Air Showerselection taking into account the one-off and secondary investment and energy efficiency ratio.

Analysis of the nature of the dust-containing gas.

The main properties of the dusty gas relevant to the selection of the Air Shower are temperature, humidity, acid and alkali content, and the number of organic solvents. Some filters can be used at high temperatures, while others can only be used at normal temperatures and humidity, and the amount of acid and organic solvents in the dusty gas has an impact on the performance and efficiency of the air filter.
