The difference between filter cartridge dust collector and bag filter

We know that both the filter cartridge type dust collector and the bag type dust collector are high-efficiency dry dust removal devices, which have the advantages of high dust removal efficiency, stable equipment operation and less wearing parts, so they are widely used in the industry. But what is the difference between the filter cartridge dust collector and the bag filter? Let's list it now!

First, the difference between the filter material and the principle

1. The filter cartridge or filter bag hard filter material is folded to form a cylinder, without skeleton, short, large spacing between cylinders, thorough cleaning, no secondary pollution.

2. The bag is sewed into a filter bag by a soft filter material, and is placed on the skeleton welded by the steel bar (commonly known as the dragon skeleton). The filter bag is tightly packed, and the filter material is long polyester fiber and its post-treatment material is mostly single layer. Ordinary industrial polyester fabric.

3, the principle of filtration surface filtration principle: filter cartridge dust collector dust does not go deep into the filter material deep filtration principle. The dust of the bag filter goes deep into the filter material, and the dust layer is built on the outer surface of the filter material to maintain the dust removal efficiency.

Second, the advantages of comparison

1. Advantages of the filter cartridge type dust collector:

1) The dust removal efficiency of the filter on the surface of the filter cartridge is much higher than that of the old dust collector, which greatly reduces the emission of harmful substances. The air purification index has reached the world advanced level, completely changing the backwardness of the old dust collector. status.

2) The filter cartridge type dust collector has no filter material wear phenomenon, and there is no movable part on the body, and it can be used for a long time without maintenance (even if the filter cartridge is replaced), which avoids the trouble of changing the filter material of the old type dust collector, saving Money saves time and effort and there is no secondary pollution.

3) The filter cartridge type dust collector is much smaller than the old dust collector of the same specification, saving civil construction space and civil construction load, and saving significant capital investment.

4) The filter cartridge type dust collector has low resistance, consumes a small amount of compressed air, and has no maintenance workload. More energy than other types of old dust collectors, saving more than 30%, any enterprise can not ignore the significant economic benefits brought by this energy-saving effect.

2, the advantages of bag filter:

1) It has the characteristics of simple operation, continuous cleaning, stable resistance, high filtration speed, no moving parts inside, simple design, etc. It is a high-performance bag filter.

2) High dust removal efficiency, it can capture dust above 0.3UM, and purify dusty gas to 15mg/m3 or even below.

3) There are few auxiliary equipments, investment is saved, and technical requirements are not as high as electrostatic precipitators.

4) It can capture dust that is difficult to recover by electric dust removal, and can collect compounds such as nitrates and sulfides to a certain extent.

5) It has good adaptability to load changes, especially suitable for collecting fine and dry dust, and the collected dry dust is easy to handle and recycle.

6) The bag filter is safer when it collects explosives with sparks or sparks.

CO2 Laser Marking Machine`s core optical components adopt US imported parts,US imported CO2 RF laser source, US high-speed scanning galvanometer, these ensure high-speed stability and continuous long hours work, CO2 RF laser source is a gas laser, the laser wavelength is 10.64μm, it`s intermediate infrared, CO2 lasers have relatively large power and relatively high electronic / optical conversion rate. CO2 gas is the working substance of CO2 laser source, CO2 and other auxiliary gas were being filled discharging tube, the gas molecules can release laser while heightening the electrode voltage and generating glow discharge in discharge tube; It will can be laser processing after the releasing laser energy expanded and focused, and then deflected by scanning galvanometer .

Marking software runs on WINDOWS platform, Chinese interface, compatible with AUTOCAD, CORELDRAW, PHOTOSHOP and other software file formats, such as PLT, PCW, DXF, BMP, etc., but also can directly use SHX, TTF font. Design any graphic by computer , easy operation, power is controlled by software, continuously adjustable.
