What is the price and principle of bag filter?

Principle: The working principle of the bag filter.

After the dust-containing gas enters the ash hopper from the tuyere, a part of the coarser dust particles and the condensed dust mass fall directly due to the inertia and play the role of pre-dust collection. The air flow into the hopper turns upwards into the box, and as it passes through the filter bag with a metal skeleton inside, the dust is trapped on the outer surface of the filter bag. The purified gas enters the clean chamber at the upper part of the filter bag and is collected and discharged into the air outlet duct.

The cleaning of the dust collector is carried out on a room-by-room basis, and its program is determined by the controller according to the adjustment of the process conditions. Reasonable cleaning procedures and cleaning cycles ensure the cleaning effect and filter bag life of this type of dust collector. The ash cleaning controller has two kinds of ash cleaning functions, timing ash cleaning is suitable for occasions when the working conditions are relatively stable, if the working conditions change frequently, the use of constant resistance ash cleaning can achieve the best coordination of the ash cleaning cycle and running resistance.

When the dust collector is working, with the continuous filtration, the dust accumulation on the surface of the filter bag gradually increases, and the resistance of the dust collector also gradually increases. When the set value is reached, the cleaning controller issues a cleaning command to remove the dust from the outer surface of the filter bag and fall into the ash hopper, and then open the exhaust valve to restore the filtration of the chamber. After an appropriate time interval, the dust collector again proceeds to the next chamber cleaning.

**: Boiler dust collector: 580-600 yuan square meter filtration area.

The ** of the bag filter is related to the nature of the dust to be removed and the temperature of the dust.

The bag filter is a dry dust collection device, which is suitable for capturing fine, dry non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and the filtering effect of fiber fabric is used to filter the dust-containing gas, when the dust-containing gas enters the bag dust collector, the dust with large particles and specific gravity settles down due to the action of gravity, falls into the ash hopper, and the gas containing finer dust is retained when passing through the filter material, so that the gas is purified. Generally, the dust removal efficiency of the new filter media is not high enough.

After the filter media has been used for a period of time, due to.

Sieve filtration, collision, retention, diffusion, static electricity and other effects, the surface area of the filter bag has accumulated a layer of dust, this layer of dust is called the primary layer, in the subsequent movement process, the primary layer has become the main filter layer of the filter material, relying on the effect of the primary layer, the filter material with larger mesh can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector are increased accordingly, and when the pressure difference between the two sides of the filter material is very large, some fine dust particles that have been attached to the filter material will be squeezed over, so that the efficiency of the dust collector decreases. In addition, too high resistance of the dust collector will significantly reduce the air volume of the dust collection system.

Therefore, after the resistance of the dust collector reaches a certain value, the ash should be cleaned in time. The initial layer can not be destroyed during ash cleaning, so as not to reduce the efficiency. The structure of the bag filter is mainly composed of the upper box, the middle box, the lower box (ash hopper), the ash cleaning system and the ash discharge mechanism.

The bag filter intercepts the dust through the filter bag, which is cylindrical and flat, generally according to the structure of the skeleton; Bag filtration is divided into internal filtration and external filtration. The external filter refers to the dust-containing gas entering the bag from the outside of the bag, and the dust collector has a skeleton support, while the internal filter type does not need a skeleton. The efficiency is generally above 99%.

**In tens of thousands to hundreds of thousands, generally depending on the material of the bag and the number of bags.

**？It varies with the size. Principle: Use filter cloth to make a cloth bag to filter dust.

Bag filter is a commonly used industrial dust removal equipment, which varies due to different specifications, generally between tens of thousands of yuan and hundreds of thousands of yuan. Its principle mainly includes the following steps:

1.Air inlet: Brings the airflow containing dust into the bag filter.

2.Pretreatment chamber: By adjusting the wind speed and inlet air volume, the dust particles are initially deposited in the pretreatment chamber.

3.Filter Chamber: The air that enters the filter chamber flows through the filter bag, leaving the dust particles in it on the filter bag, while the clean air flow is discharged through the filter bag.

4.Cleaning system: During the operation of the bag filter, dust particles will gradually accumulate on the filter bag, which will affect the working efficiency of the dust collector. Therefore, the filter bags need to be cleaned regularly with a cleaning system to maintain the dust removal effect.

The bag filter can effectively filter out some small dust particles, and is widely used in steel, electric power, chemical, cement and other industries. Its dust removal effect is very reliable, and it has very important application value in industrial production.

As of January 29, 2020, the bag filter** is about 5-150,000.

According to different processes and different configuration parameters, the bag filter is generally about 5-150,000. A baghouse is a dry dust filtering device. It is suitable for the capture of fine, dry, non-fibrous dusts.

The filter bag is made of textile filter cloth or non-textile felt, and the dust-containing gas is filtered by the filtration effect of the fiber fabric, when the dust-containing gas enters the bag filter, the dust with large particles and specific gravity settles down due to the action of gravity and falls into the ash hopper, and the gas containing finer dust is blocked when passing through the filter material, so that the gas is purified.

The ** of bag filter varies depending on the brand, model, specification, configuration and other factors. Generally speaking, the power is about 5000mh, the processing airflow is about 5000m h, and the price of the small bag dust collector made of polyester fiber is between 5000 yuan and 10000 yuan. The large-scale bag dust collector with large air flow, high-end bag material and complex ash cleaning system is between hundreds of thousands of yuan and millions of yuan.

It is recommended that you consider your needs, budget, and cost-effectiveness before making a purchase.
