What are the main components of a baghouse?

I will now introduce you to the whole bag dust collector: the bag dust collector is mainly composed of filter bags, bag cages, flower boards, bag chambers, clean air chambers, ash hoppers, air inlet and outlet ducts, ash cleaning systems and ash conveying systems.

Working principle: install the air collection hood above the dust generation point, the air collection hood directly adsorbs away the air with dust, and directly transports it to the bag dust collector through the pipeline, the cloth bag inside the dust collector directly filters out the dust, the clean air is directly discharged, the dust falls into the ash hopper, and the dust can be cleaned regularly. If the amount of dust is large, it can be disposed of with a discharger.

The amount of dust is small, and it can be used manually to deal with which parts of the bag dust collector are composed of, Structural frame and box: The structural frame is used to support the dust collector body, ash hopper and ash discharge equipment, etc.; The box includes the upper box, the middle box and the ash hopper.

Filter bag, cage bone and pattern plate: The filter bag and cage bone form the ash filtration system of the dust collector; The pattern plate is used to support the filter bag assembly and separate the filter chamber (including the dust section) and the clean air chamber, and is used as the maintenance platform for the filter bag assembly of the dust collector; The filter bag assembly is loaded from the pattern plate.

Air intake system: including air intake diversion header, deflector plate, etc.

Exhaust system: includes the dust collector purification gas emission system composed of exhaust pipes, etc.

Ash unloading system: The air cannon and manual plug-in valve installed on the ash hopper of the dust collector constitute the ash unloading system and ash conveying equipment of the dust collector.

Access platforms for platforms, railings, ladders and pneumatic valves.

Rain shelter on the top of the dust collector: used to protect the top device of the dust collector such as the electromagnetic pulse valve.

Dust collector lighting system.

2) Protection system.

Including bypass system, filter bag leak pick-up device.

3) Compressed air system.

The baghouse is mainly composed of the following components:

1.Air inlet: used to introduce dusty gases into the dust collector.

2.Box: It is the main body of the dust collector, and the shell is generally made of steel plate and lined with screens.

3.Support frame: A bracket for placing the screen, usually made of metal.

4.Screen: that is, bag filter material, used to filter dust particles in the dust removal gas, commonly used filter material materials are polyester fiber, fiber felt, etc.

5.Ash cleaning system: remove the dust on the filter bag, mainly including fan, back-blowing air circuit, pulse valve, etc.

6.Ash discharge system: used to collect and process the dust after ash cleaning, bag making machine, hopper and other equipment can be used.

7.Control system: It is used to control the operation of the dust collector, including manual control and automatic control.

Hello dear, what are the main components of a baghouse? The bag filter is composed of an upper box, a bag chamber, an ash discharge device and a pulse jet ash cleaning system. The plate inside the baghouse is divided into two parts.

The above part is called the upper box or clean air chamber. The following sections are called. Inside the clean room:

The clean room is equipped with a blowing pipe, a compressed air bag, a pulse valve, a compressed air pipe, a smoke exhaust pipe, a maintenance door, etc. The clean gas chamber is divided into several chambers according to its specifications, separated from each other by steel plates, and not ventilated to each otherFilter chamber:

The filter chamber includes a flower plate, a filter bag assembly, an ash hopper, a flue assembly, etc. The filter bag material is a flexible and breathable medium, generally needle-punched or coated material. The filter bag is supported by a metal skeleton to ensure that it will not be filtered.

Three-row ash equipment: at the outlet of the ash hopper. Contains ash discharge valve, screw conveyor or conveying chute.

Bag Dust Collector Cleaning System: Including pulse spray valve, poppet valve assembly and compressed air piping.

Negative pressure dust collector: The fan is placed after the dust collector, and the dust collector works under negative pressure。Since the dusty gas enters the fan after purification, the wear and tear on the fan is small, and this method is used more.

The fan is located behind the bag filter to form a negative pressure inside the dust collector, so a sealed structure must be adopted. Because it is a closed structure, it is easy to take measures such as heat preservation because it is expensive to build a structure, so it is suitable for handling condensable gases with high humidity.

The purpose of the dust collector.

A dust collection hood is set up in each ash place, and the dust-containing gas is transported to the dust removal device through the pipeline gas path, in which the dust is collected in the dust removal device after the gas-solid separation is carried out, and the clean gas is introduced into the main pipe or directly discharged into the whole set of equipment into the atmosphere, that is, the dust removal system, and the dust collector is an important part of the system.

From the perspective of ventilation and dust removal, dust is all solid small particles that can float in the air for a long time, and is a dispersion system, called aerosol, in which air is the dispersed medium and solid particles are the dispersed phase. A dust collector is a device that separates these small solid particles from aerosols.

The above content refers to Encyclopedia - Dust Collector.

The dusty gas passes through the filter bag and is blocked on the surface of the bag, and the filtered clean gas is sent out through the dust collector. The dust accumulated on the bag is blown off by the reverse air blowing or the pulse blowing pipe, and the dust is cleaned by the dust of the air flow sprayed by the pulse blowing pipe. Dust falls on the discharge equipment below the hopper, allowing the bag to circulate and filter the flue gas dust.

Reading guide: The bag filter is a device that uses a cloth bag as a cleaning device for dust particles, and the bag is made through some weaving operations, which can easily collect the dust, and then clean up the dust. The emergence of this kind of bag filter has made the dust removal equipment slowly develop and gradually improve, and now I will take you to learn more about the bag filter.

1. Types of bag filters:

1) Mechanical vibration type.

Mechanical vibration type is to keep the dust bag in a state of constant vibration through some mechanical devices, so as to achieve the cleaning effect of dust, which can be used for dust treatment in some gap environments and so on.

2) Chamber-splitting back-blowing type.

The chamber reverse blowing type uses the structure of the chamber, and then converts the air flow through the corresponding valve, and at the same time uses its anti-air flow effect to make the dust bag expand or shrink, and then achieve the effect of going out into a map.

3) Nozzle blowback type.

The nozzle back-blowing type realizes the positive and backward blowing effect of the airflow with the help of a high-pressure fan, which makes the bag deformed, and at the same time, it is accompanied by shaking, so that the dust is removed from the dust bag.

4) Pulse jet type.

The first power of pulse jet cleaning dust is the compression of air, and the compressed air is released by the pulse injection machine, so that the compressed air enters the dust bag, so that the inside of the dust bag expands, and then the dust is removed.

Second, the characteristics of the bag filter:

The efficiency of dust removal is high, the cleanliness reaches 99%, and the fine dust also has a good absorption effect.

The wide range of air volume treatment is very suitable for the cleaning of flue gas particles in some industries. It can significantly reduce the amount of pollutants emitted.

The structure is simple to make, and the maintenance operation of the dust collector can be easily carried out.

The cost is relatively low compared to some other electric precipitators, and the efficiency of dust removal is equal.

It can be operated at high temperatures and has the characteristics of high temperature resistance.

The material of the dust will not be affected in any way, no matter what kind of dust it is, the baghouse can remove it.

Third, the method of ash cleaning.

1. The gas cleaning method expands the dust bag through some high-pressure gas, and then achieves the dust removal operation.

2. Cleaning method for beating: the dust bag is beaten, and then the dust will be automatically removed.

3. Cleaning method of manual beating: manually patting the dust bag and cleaning the dust on the dust bag.
