Mobile dust collector application and working principle

The mobile dust collector ("Tomorrow" series mobile dust collector) generally uses a bag filter, which has high dust removal efficiency and can achieve a fine dust efficiency of over 99%. However, it is not advisable to purify dust-containing gas containing oil mist, condensed water and dust, and smoke with explosion hazard or spark. When the dust concentration is greater than 10g/m3, a pre-cleaning dust collector should be added.
Application of mobile dust collector: In the architectural design of various workshops, there are different levels of dust pollution, including chemical pharmaceutical, food processing, mechanical processing, electronics, metallurgy, foundry, carbon materials, building materials and other industries, especially In the pharmaceutical production lines, tablet presses, granulators, mixers, batching, mixing, vibrating screens, pulverizers, weighing, caps, Chinese medicine pretreatment, etc., the air is required to be dedusted and purified. A complete dust removal system should include the following aspects:
1. Use a dust hood to capture the dust-containing gas generated during the process.
2. The trapped dust-laden gas is transported along the pipeline to the dust removal filter device under the action of the fan.
3. Separate the dust in the dust removal equipment.
4. The purified gas is discharged to the atmosphere.
5. Collect and dispose of the separated dust.
According to the characteristics of dust generation, the dust removal equipment of the general clean house is selected as a filter dust collector. Due to the large number of dust spots in the factory, the dust removal pipeline is arranged too long, which causes the dust removal effect to be affected. So the best way at the moment is to use a mobile dust removal device. Tomorrow's series of mobile dust collectors often use medium-efficiency (or high-efficiency filters) for dust removal and purification. It has high dust removal efficiency (up to 95%-99.5% for 0.3um dust), strong adaptability, flexible use, stable operation, simple maintenance and easy recycling of dust. Therefore, mobile dust collectors are widely used in various industries such as medicine, food, electronics, chemical, machinery, metallurgy, ceramics, cement, etc., among the various high-efficiency dust collectors, they are the most competitive dust removal equipment. .
Working principle of mobile dust collector: When dusty air passes through the filter bag, the dust is retained on the filter bag due to the filtering, interception, collision, diffusion and static electricity of the fiber to form the initial filter layer and the initial filter layer. Has a high dust removal efficiency. Therefore, the filtering effect of the bag type mobile dust collector is mainly based on the initial filter layer and the dust layer which is gradually accumulated later. As the dust collecting layer becomes thicker, the pressure difference on both sides of the filter bag becomes larger, so that the resistance loss of the dust remover increases, and the amount of gas to be treated is correspondingly reduced. At the same time, as the speed of air passing through the pores of the filter bag is increased, the dust removal efficiency is lowered. Therefore, after the dust collector is operated for a period of time, (generally after a shift), it needs to be cleaned to remove the dust collecting layer, but the initial filter layer is not damaged, so as to avoid the efficiency drop.
