For high vacuum fume extractor supplier, the correctness of cleaning pressure and air flow rising speed determines whether it can run stably. The correct selection of the cleaning pressure and air flow rising speed of high vacuum fume extractor supplier can control pollution and reduce the cost of dust removal on the premise of increasing the dust removal rate, which can achieve economic benefits.
First, the cleaning pressure of high vacuum fume extractor supplier is introduced. This parameter is an indicator to be considered when designing high vacuum fume extractor supplier. This is directly related to the high vacuum fume extractor supplier can be applied in what kind of operating environment. Generally, we are divided into high pressure valves and low pressure valves according to the different air pressures of high vacuum fume extractor suppliers, and the corresponding pressure ranges are as follows: High pressure (0.5-0.7MPa), medium pressure (0.35 ~ 0.5MPa), low pressure (0.2 ~ 0.35mpa) and ultra-low pressure (below 0.2mpa), the specific selection also needs to be selected according to the specific operating environment. Generally, for small high vacuum fume extractor suppliers, we will choose high pressure cleaning in most cases, and the same for the opposite situation, we need to choose low pressure control.
The dust removal rate of high vacuum fume extractor supplier and the type of filter material are positively correlated with the dust condition attached to the dust bag. Generally speaking, the dust removal rate of new filter bags is not ideal, but when there are two to three grams per cubic meter, its dust removal rate will be increased a lot, basically can reach more than 90%; When it can reach 150 grams per cubic meter, the dust removal rate can be reached or exceeded.
Classification of high vacuum fume extractor supplier:
1, according to the shape of high vacuum fume extractor supplier's cloth bag can be divided into round bag dust collector and flat bag dust collector:
1) At present, most high vacuum fume extractor suppliers use round high vacuum fume extractor suppliers, Because the force of this high vacuum fume extractor supplier is uniform, the connection of the skeleton is simple, and the assembly and repair are convenient.
2) Flat high vacuum fume extractor supplier internal skeleton layout is compact, can be arranged in the same volume of large filtration area, under normal circumstances can save 20%-40%, Single flat high vacuum fume extractor supplier its structure is more complex, the production requirements are high, the effect of cleaning ash is not as good as the round high vacuum fume extractor supplier.
2, according to the location of the air intake can be divided into upper air dust collector and lower air dust collector:
1) The dust bearing gas enters the dust collector from the bottom of the bag room or the upper part of the ash hopper. This dust collector is relatively simple, but when the gas in the bag room is top-down, it is opposite to the settling direction of the dust, which is easy to make the dust fill the core and reverse blow the surface of the bag, thus affecting the dust removal effect and increasing the resistance.
2) The upper air intake mode contains dust from the bag room into the dust collector, the direction of dust settlement is consistent with the flow direction of the air flow, which is conducive to dust settlement, but the bag needs to set the upper and lower two flower plates, the structure is more complex, and it is not easy to adjust the tension of the bag.
3, according to the direction of the filter bag, the external filter type high vacuum fume extractor supplier and the internal filter type high vacuum fume extractor supplier:
1) The outer filter type dust containing gas has the outside of the bag like the inside of the bag to flow, the dust is blocked in the outer surface of the bag, the outer filter type bag can be round bag and flat bag, and the skeleton can be set inside the bag to prevent the bag from being sucked. The cleaning methods such as pulse jet blowing and high pressure air flow back blowing are mostly used in the external filter type.
2) The inner filter dust containing gas flows from the inside of the filter bag to the outside of the bag, and the dust is blocked in the inside of the bag. The inner filter type is used in the round bag, mechanical vibration, reverse airflow, air ring reverse blowing and other cleaning methods, the inner filter type because the outside of the bag is clean gas, when the gas filtered by the bag is five poisonous and the temperature is not high, the maintenance in the bag can be carried out without stopping. The air flow speed of the inner filter type round bag is large, and the air flow contains coarse particles. Will seriously damage the cloth bag.
