Working Principle

Bag filter is a pressurized filtration device, which mainly consists of a filter cylinder, a filter cylinder cover and a quick-opening mechanism, a stainless steel filter bag reinforcement mesh and other main components. The filtrate flows into the filter bag from the side inlet pipe of the filter shell. , the filter bag itself is installed in a reinforced mesh basket, and the liquid penetrates through the filter bag of the required fineness level to obtain qualified filtrate, and the impurity particles are intercepted by the filter bag. It is very convenient to replace the filter bag of this machine, and there is basically no material consumption for filtration.

Selection Table

Characteristics

1. The support basket has a high opening rate, ensuring large flow and small volume of the filtration system;

2. The support basket has a high opening rate, which also increases the actual use area of the filter bag and extends its service life;

3. The top-entry design makes the replacement of filter bags quick and easy;

4. Top-entry design and evenly distributed streamlines make the impurities trapped in the filter bag medium evenly distributed;

5. The high-strength support basket effectively supports the filter bag, prevents fiber migration, and ensures high filtration efficiency;

6. The high-strength support basket also ensures the high mechanical strength of the filter bag;

7. Special magnetic filters or activated carbon or diatomite can be put in the filter bag to remove iron impurities or adsorb organic matter.;

8. The standard specification support basket is suitable for all standard size filter bags, making the filter bags highly interchangeable;

9. Closed filtration system, strong safety;

Application

1. Weakly corrosive materials in chemical and petrochemical production, such as water, oil, ammonia, hydrocarbons, etc.

2. Corrosive materials in chemical production, such as caustic soda, soda ash, concentrated and dilute sulfuric acid, carbonic acid, aldehyde acid, etc.

3. Low-temperature materials in refrigeration, such as liquid methane, liquid ammonia, liquid oxygen and various refrigerants.

4. Materials with hygienic requirements in food and pharmaceutical production, such as beer, beverages, dairy products, syrups, etc.
