Mechanical vibrating bag filter, pulse jet bag filter principle

The mechanical vibrating bag filter has a unique appearance, compact structure, good ash cleaning effect, and more practical installation space. The mechanical vibrating bag dust collector comprises a dust collector shell, a flower plate and a plurality of rapping rods and cloth bags, an air inlet is opened in the middle part of one side of the dust collector shell, an air outlet is opened in the upper part of the other side, an ash cleaning door is opened at the bottom of the dust collector shell between the air inlet and the air outlet, a flower plate is installed in the dust collector, the flower plate is installed between the air inlet and the air outlet and the dust collector is divided into dust removal area and exhaust area, the upper end of a plurality of beating rods and cloth bags is installed on the flower plate, it also comprises: crank mechanism, a beating frame and a pendulum rod, The lower end of a plurality of vibrating rods and cloth bags is equipped with a vibrating frame, a plurality of beating rods and cloth bags are inserted in the beating frame, the top of the beating frame is fixed on the wall of the dust collector by two pendulum rods, one side of the beating frame is connected with the crank mechanism, and the mechanical vibrating bag dust collector has the advantages of good dust removal effect, will not cause secondary pollution to the environment and directly protects the health of workers.

Using the electric push rod device installed above the hole of the bag room, the air inlet of the back-blowing pipe is opened, and the natural air of a certain air volume is sucked in when the bag room is in a negative pressure state to shake the bag to achieve the purpose of ash cleaning. It only takes half a minute for each chamber to remove the dust of dozens of bags in the bag.

I thanked it, but understanding is understanding, and it is still a little difficult for Yan to accept the feelings, so she simply didn't think about it.

The kind of vibration motor is very simple, and the effect is not ideal.

The structure of the pulse 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.

Yes. In addition to the correct selection of filter bag materials, the ash cleaning system plays a decisive role in the performance of the pulse bag filter.

The role of sex. For this reason, the cleaning method is one of the characteristics that distinguish the pulse bag filter, and it is also an important one in the operation of the pulse bag filter.

Ring. It works by spraying compressed air into the dust filter bag at high speed in a very short period of time, while inducing air formation that is several times the amount of air sprayed.

The air wave makes the filter bag from the bag mouth to the bottom produce a sharp expansion and impact vibration, and the filter bag is formed in a short period of time

The wavy deformation of the "drum" causes the dust layer to deform and break, and it is separated from the filter cloth in a lump and falls under the action of gravity. When the ash is cleaned, the ash is cleaned.

The air flow expands and deforms the filter bag and passes through the bag wall and dust layer.

Product principle and process flow.

Under the action of the ventilator, the dusty gas is sucked into the intake manifold, evenly distributed to each inlet chamber through each inlet branch, and then pours into the filter bag, a large amount of dust is trapped on the filter bag, and the air flow is purified through the filter bag. The purified airflow passes through the bag chamber along the smoke exhaust into the chimney and into the atmosphere.

With the thickening of the dust attached to the surface of the filter bag fabric, the resistance of the dust collector continues to rise, which requires regular cleaning to reduce the resistance to below the specified lower limit before the dust collector can operate normally. The whole ash cleaning process is mainly completed by the action of the high-pressure air storage bag, solenoid valve, blowing pipe and ash cleaning control mechanism. First of all, the control system automatically sequentially hits the solenoid valve, and the high-pressure air is blown back through the blowing pipe, so that the dust adhered to the filter bag is shaken and falls off into the ash hopper.

Then the solenoid valve is closed, the cleaning operation of the system is over, and the filter bag is restored to the filtering state. The control system then opens other solenoid valves, and cleans the ash of other filter bags, and all the filter bags are cleaned after the ash cleaning cycle, so as to achieve the purpose of ash cleaning, the dust collector fully recovers the filtration state, and the ash in the ash hopper is discharged to the conveyor by the pneumatic ash discharge valve at the bottom.

Bag filter is a kind of high-efficiency dry dust collector, which relies on the filter bag made of fiber filter material, and more importantly, purifies the gas through the dust layer formed on the surface of the filter bag, and its dust removal efficiency may reach more than 99% for almost all dust in the general industry.

Baghouse

As a high-efficiency dust collector, it is widely used in various industrial waste gas dust removal, such as light industry, machinery manufacturing, building materials, chemical industry, non-ferrous smelting and iron and steel enterprises.

Dear, hello, I have inquired for you, the bag dust collector dust collector mountain pre-judgment answer; The bag filter is mainly used to filter the dust-containing gas with filter material (fabric or felt) to achieve the purpose of dust removal. The filtration process is divided into two stages, the dusty gas passes through the clean filter material, and the main role of filtration at this time is the retention of the filter material fibers. When the retained dust continues to increase, a part of the dust is embedded into the filter material, and a part is covered on the surface of the filter material to form a dust layer, which mainly relies on the dust layer to filter the dust-containing gas.

After the dust-containing gas enters the dust collector, the airflow velocity decreases, the larger particles in the smoke and dust are directly washed and precipitated to the ash hopper, and the rest of the dust particles are filtered through the filter bag from the outside to the inside, and the clean flue gas is discharged from the inside of the filter bag, and the fly ash is blocked in the filter bag.

The working mechanism of the bag filter is that the dusty flue gas passes through the filter material, and the dust particles are filtered down, and the filter material mainly relies on inertial collision to capture coarse-grained dust, and the fine-grained dust is mainly collected by diffusion and screening. The dust layer of the filter material also has a certain filtering effect. The effectiveness of a bag filter is related to a variety of factors, but it mainly depends on the filter material.

The filter material of the bag filter is a cloth or felt woven from synthetic fibers, natural fibers or glass fibers. The cloth or felt is sewn into a cylinder or flat filter bag as needed. According to the nature of the flue gas, the filter media suitable for the application conditions is selected.

Generally, when the flue gas temperature is lower than 120 and the filter material is required to have acid resistance and durability, polyester flannel cloth and polyester needle felt are often selected; When dealing with high-temperature flue gas (<250), graphitized glass cloth is mainly used; In some special cases, carbon fiber filter media is selected.
