What is the function of the dust collector skeleton?

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 dust removal skeleton is the pivotal department in the operation of the bag dust collector, the dust removal skeleton is the rib of the dust removal bag, and is an important accessory of the dust collector, and there are also stretched venturi tubes, which can be welded on the cage mouth according to user requirements, venturi tubes, short tubes, hanging mouths, bag hose hoops and other accessories, and can be made according to customer requirements Non-scale cage frame, dust removal skeleton is characterized by firm welding, smooth and straight appearance, dust removal skeleton with patented technology, one-time molding automatic welding equipment manufacturing and production, product function superior, no desoldering, burr, The design structure is strong and reliable, easy to install and long service life.

In the case of negative pressure operation and external filter type of dust removal skeleton, dust-containing air flow enters the filter bag, no matter what kind of ash cleaning method is chosen, after the dust removal skeleton runs for a period of time, the problem of dust accumulation will occur at the bottom of the filter bag. These deposits are deposited by the dust on the inner wall of the filter bag when the ash is cleaned, which can be used. But the internal structure of the existing dust removal skeleton (cage frame, filter bag) is not convenient for the utilization of this part of the ash accumulation.

The existing way to remove the dust is to open the top lid of the bag chamber first, and then take out each cage rack and filter bag, and clean the ash one by one. This method has a large workload, long ash cleaning time and high labor intensity.

The mechanism of filtration and dust removal is the comprehensive effect of short-range trapping mechanisms such as sieve effect, diffusion sedimentation, direct entrapment, inertial collision and electrostatic adsorption. When dust-laden air passes through filter media such as grids, fabrics, nonwovens, foams, etc., the dust layer formed by the dust inside or on the surface of the filter material, as well as the filter layer formed by the upper layer of the powder, are captured and separated from the air flow. With the thickening of the dust layer, the dust layer needs to be removed regularly to ensure the continuous progress of the dust removal process.

Textile fiber dust collectors are classified according to different dust collector structures, and textile fiber dust collectors include dust cage filtration, filter bag filtration and filled filter bed filter dust collectors.

1) Dust cage filtration: The dust cage is a cylinder surrounded by a metal grid, and the openings at both ends of the cylinder communicate with the air duct. The dust cage uses the airflow pressure generated by the fan to press the dusty air to the surface of the dust cage, and most of the linter and impurities are trapped on the surface of the dust cage.

A filter fiber mesh layer is formed, and at the same time, the dust-containing air through the dust cage enters the second stage filtration device through the channels on both sides of the dust cage. The pre-separator can be seen as a type of dust cage filtration. The advantages of dust cage filtration are that there are fewer auxiliary equipment, simple and convenient management, and the reuse rate of the filtered cotton basket is higher, and it is generally assembled into dust filtration equipment with other filtration methods.

The disadvantage is that the processing air volume is not large, the area is relatively large, and the power consumption is more.

2) Filter bag filtration: The filter bag (called the dust removal bag) is a columnar body surrounded by a single layer of fabric, usually round, which is characterized by a simple structure and is convenient for ash cleaning. When the dusty air passes through the filter bag, the dust is separated from the air flow with the help of screening, collision, interception and other effects.

The advantage of filter bag filtration is that the filtration efficiency is high, and the full efficiency of dust removal can reach more than in the dust room of the textile mill, with simple structure and low power consumption. The disadvantages are that it is easy to fire, the filter bag is easy to condensate, the amount of filtered air per unit area is small, the amount of filter cloth is large, and the dust concentration of the filtered air is high and the working conditions are poor in a short time after ash cleaning.

3) Filled filter bed filtration: Filled filter bed is to cover porous filter materials such as foam, nonwoven, and plush on mesh drums, flat plates and other components. With its good surface filtration and internal filtration effect, the dust is separated from the air stream, and the advantage of filled filter bed filtration is the large filtration air volume.

Are you going to make a dust collector? The dust removal component of the dust collector is very right, let's talk about the main thing! There are gas collection hoods, air inlet pipes, dust collectors, exhaust pipes, ventilators, motors, dust discharge devices, dust treatment and ** systems and their ancillary facilities.

In terms of workflow, the power generated by the fan is used to send the dusty gas to the dust removal equipment through the exhaust pipe for purification, and the purified gas is discharged from the chimney through the exhaust pipe, and the dust is discharged from the exhaust device. The motor is the equipment that provides power for the fan, and the other equipment is the supporting facilities.

There are too many dust collector accessories, if you are interested, you can consult us or find some large-scale regular manufacturers on the Internet to consult.

2.Injection system: including main air pipe, injection pipe, pulse valve, controller.

3.There are two forms of ash hopper and ash discharge part: one is that the ash hopper is directly connected with the ash discharge valve, and the other is that the ash hopper is connected with the ash discharge valve through conveying equipment (such as screw conveyor).

The dust collector is divided into: upper box, ash hopper, pulse valve, skeleton, filter bag, flower board, plug board valve, ladder, guardrail, inspection door, electric control cabinet, etc.

The dust removal system consists of three parts: the body, the pipeline, and the dust collection hood, and the body includes: the box and the injection cleaning system.

The box body includes an exhaust pipe, a fan, a clean air chamber, an access door, and an ash hopper; Injection system: including main air pipe, injection pipe, pulse valve, controller. Provided by Zhengzhou Yuanchuang Machinery

The difference between the galvanized dust removal skeleton and the ordinary dust removal skeleton is:

The galvanized ash removal skeleton is cold galvanized, also called electrogalvanizing, and the ash removal skeleton is degreased, pickled and passivated, and then put into the aqueous solution composed of zinc salts, connected to the negative electrode of the electrolysis equipment, and the cold-rolled steel plate is placed on the opposite door of the pipe, and the positive electrode connected to the electrolysis equipment is connected to the switching power supply, and a layer of zinc will be accumulated on the ash removal skeleton by moving the current from the positive electrode to the negative electrode. The ash removal skeleton solved by galvanizing has a smooth appearance, no zinc tumor, burrs, silver or colorful, and has a certain acid resistance, and acid resistance is a common ash removal skeleton at this stage.

The galvanized skeleton is the surface layer of the dust removal skeleton after it is welded and formed by electric welding. The galvanized ash removal skeleton is made of one-time forming full galvanized, the surface layer is smooth and straight, and the dust removal bag will not be damaged without causing burrs. The galvanized skeleton is the "rib bone" of the dust removal bag, it should be lightweight, conducive to installation and maintenance, and the quality of the galvanized skeleton immediately endangers the filtration and service life of the dust removal bag.

Characteristics of galvanized dust removal skeleton: strong electric welding, smooth and straight surface, light use, conducive to installation and maintenance. Specifications and models of ash cage bones: ring, oval, flat, envelope bag, and various structures customized according to customer regulations.
