What are the advantages of pulse bag filter? , The first reason
Most environmental engineers will agree that filter cloth filtering technology is superior to electrostatic dust removal technology.
Therefore, most of the new types of vacuum cleaners installed are bag filters (bag filters). Bag filters and electrostatic precipitators have the following main advantages: high efficiency (low emissions); reduced maintenance (parts, labor); Can be maintained online (when the bag filter is isolated by the compartment); there are not many restrictions on the change of dust properties at the entrance. It can handle increased ventilation; when the process conditions change, the filter medium can be changed.
The main advantage of the pulse bag type dust collector is that it reduces the emission concentration. With the increasingly strict global air quality standards, the dust emitted from the chimney has become an increasingly important factor in determining the dust removal system. Many esp designs cannot simply meet the requirements Very low emission levels. Retrofitting the electrostatic precipitator can effectively reduce the concentration of soot emissions and is considered a feasible solution.
However, the modification of the electrostatic precipitator is not suitable for situations where the dust is too fine, difficult to collect, the specific resistance of the dust is too high or the electrical conductivity is too high to maintain a good charge, so that the electrostatic precipitator cannot collect the dust well. For these working conditions, the use of bag filter technology is a good choice.
What are the advantages of pulse bag filter? Second, the characteristics of pulse jet bag filter
After entering the bag filter, the dust-containing gas is distributed to the filter element through the guide plate. The function of the inlet part is to reduce the speed of entering the dust and use the principle of gravity to directly settle large particles of dust, so that the airflow reaching the filter element is evenly distributed. The dust air flow will not cause excessive wear to the filter element. When the dust-containing gas is guided through the filter element, the purified gas passes through the filter element and enters the clean air chamber (upper panel), and the dust is trapped outside the filter element. The cleaning gas is led out of the chimney by the fan through the clean air chamber.
When dust is collected by the filter element, it is necessary to periodically perform dust removal on the surface of the filter element to maintain the desired operating resistance level of the dust collector. During dust removal, when compressed air is introduced directly into the inside of the filter element, the The dust cake can be removed immediately. The clean compressed air is adjusted by the pulse blowing valve and directly enters the filter element through the blowing pipe. The dust removal of the pulse bag type dust collector filter element can be performed online. The filter cake is peeled from the outer surface of the filter element and gradually enters the ash hopper through the ash cleaning process. The quick ash removal of compressed air is the only way to keep the outer surface of the filter element clean and working properly.
Compared with other bag type dust collectors, pulse bag type dust collectors have the following advantages: pulse bag type dust collectors can be made very compact, and their dimensions can be changed. The equipment contains a relatively small number of moving parts, and the pulse injection valve in these parts may need to be maintained or replaced. Since most of these moving parts are located outside the bag filter box, maintenance and replacement are very convenient. Can be installed in a clean air room (installed in a vacuum cleaner from above) or in a dust collection room (installed in the lower part of a vacuum cleaner). The traditional pulse spray bag filter uses a filter bag and a frame with a metal venturi tube (for guiding the clean compressed air in the blow tube). The modern new bag filter uses a pleated filter element, which combines the traditional filter bag and frame Into a filter material and a frame, replacing the traditional filter bag. The pleated filter element can be used to increase the total filtration area and further shorten the installation time of the element.
The design of the pulse bag type dust collector is being selected as the main bag type dust removal method by many countries in the world. Many factories have changed the dust removal method of the mechanical vibration type and pulse bag type dust collector to the pulse type. At present, most manufacturers of bag filters can provide pulse dust removal technology as an important part of their production lines.
What are the advantages of pulse bag filter? , In history, one of the problems that attracted more attention for bag filters is their ability to handle high-temperature dust gases. This is one of the reasons why electrostatic precipitators are so popular in power plants, cement plants and other industries.
