In industrial dust removal and purification, filter bags are a commonly used purification product. Many small and medium-sized enterprises will choose this more convenient and faster purification method to purify some dust and stains in production. In order to adapt to different filtration and ash removal stages, filter bags are also divided into various filter bags, which can be divided into liquid filter bags and gas filter bags.
liquid filter bag
The liquid filter bag has the characteristics of high dirt holding capacity, strong corrosion resistance, good temperature resistance, large flow rate, simple operation, long service life, and no fiber shedding.
Application of liquid filter bag: various coating equipment top cotton filter and frame type, bag filter, suitable for fine chemical industry, oil products, food and drug, water treatment and other places.
The main service object of the gas filter bag is to provide a dust-free production environment for industrial production, or for dust removal treatment, which can be divided into air conditioning system filter bags and dust removal filter bags. These two filter bags are more widely used than liquid filter bags, which are used by almost most industrial manufacturers. For production lines, computer rooms, hospitals, laboratories, sterile rooms, etc., these gas filter bags can be found everywhere.
Bag filter is used a lot in our daily life, how should we choose it? How does it work? The working principle of bag filter is pressure filtration. It consists of three parts: filter container, filter bag and support basket. The liquid flows from the filter bag to the outside of the bag, and the filtered particles will be intercepted in the bag, which is the working principle of the bag filter.
Bag filters also have their own unique characteristics, which must be understood when choosing a filter:
(1) The filter bag has a long service life
(2) The flow capacity of the filter bag filter is good
(3) The filter bag filter has high filtration efficiency and low cost
Pay attention to the following three points when choosing a bag filter:
1. To fully understand the filter material, you must first find the available filter material, and you must know the liquid name of the filter. Then evaluate its working temperature, pressure, condition, pH value, etc. one by one to remove bad filter materials. Use should also be considered during the selection process.
2. We should understand the accuracy of filtering. In fact, this is invisible to the human eye, and some people find it difficult. In fact, we just need to find out the units of precision for precision and nominal precision.
3. Can provide data for professional filter equipment merchants, they can help you calculate how many filters you need.
The bag filter can effectively remove impurity particles in the filtrate, and can be used as a fine filter or trap. The bag filter mainly consists of a housing, an inner support basket and a filter bag. The filtrate enters the filter bag from the top of the filter and is discharged from the bottom, and the impurities of the filter material are cut off in the filter bag. When the filter bag is blocked, open the filter end cover, take out the filter bag, replace with a new filter bag, and the old filter bag can be cleaned and used.
