Example of bag filter quotation What are the bag filters?

What is the performance of bag filter? What is a bag filter? There are many common vacuum cleaners, including well-known floor vacuum cleaners. I recommend a special design today, so what is their dust removal effect? Is it really worthy of our trust and purchase? Through the examples in the following small series, we can know that this kind of bag filter is not suitable for small household appliances in daily life. On the contrary, it is a dry dust filter, which occupies a relatively large area and is used to capture fine and dry dust. You may wish to refer to the following to understand.

First of all, what is a bag filter?

According to the national standard "classification and specification performance expression method of bag filter", bag filter is divided into five categories. Ash cleaning method is the main symbol of bag filter classification;

(1) mechanical vibration

There are two types of bag filters, non-compartment structure suitable for intermittent operation and compartment structure suitable for continuous operation. They use mechanical devices (including manual, electromagnetic or pneumatic devices) to vibrate the filter bag and clean the dust.

(2) Backblowing grade of combustion chamber

A bag-type dust collector adopts a chamber structure, and uses a valve to switch the airflow from one chamber to another, and under the action of reverse airflow, the filter bag is forced to contract or expand to clean dust.

(3) Nozzle blowback grade

Bag filter (all non-compartment structure) uses high-pressure fan or compressor to provide back-blowing airflow, and through moving nozzle to back-blow, the filter bag is deformed and shaken, penetrating the filter material and cleaning the dust.

(4) Combination of vibration and blowback.

Mechanical vibration (including electromagnetic vibration or pneumatic vibration) and back-blowing bag filter (both of which are divided into warehouses).

(5) pulse injection

Bag filter takes compressed air as the power to clean dust, and uses pulse blowing mechanism to release compressed air instantly, which induces secondary air to be injected into the filter bag at high speed for many times, so that the filter bag expands rapidly and cleans dust through impact vibration and reverse airflow.

Second, the bag filter quotation

From thousands of dollars to millions of dollars. First of all, what kind of environment should be provided (depending on what kind of cloth bag is used) and how much dust needs to be treated (choose a dust collector with large filtration area)
