tig mig portable fume extractor is a dry filter device. It is suitable for capturing fine, dry, non-fibrous dust. The dust bag is made of textile filter cloth or non-textile felt, and the filter effect of fiber fabric is used to filter the dust containing gas. We all know that the bag dust collector has the corresponding resistance when it runs, which mainly comes from the pipeline, elbow, inlet and outlet, dust bag, smoke pipe and so on. The resistance of the dust collector is directly related to the length of the pipeline, the number of elbows, the material of the cloth bag, and the filter resistance. The operating resistance of tig mig portable fume extractor is generally between 1200-2000pa.

tig mig portable fume extractor is equipped with an electromagnetic pulse valve to open the pulse valve, so that the compressed air radiates from each hole of the blow pipe to the corresponding Venturi pipe, and the dust on the filter bag is cleaned to keep the bag smooth and continuous. The cleaned material is delivered by a hanger under the bag. When the bag filter starts using a new filter bag, it relies on the inertial collision between dust particles in the fiber and fabric holes. It is intercepted directly by static and chaotic, brown dust collecting dust. When a layer of dust is formed on the fabric, the dust is collected through the shielding effect of the dust layer at the dust removal rate of the existing types of exhaust cleaning precipitators and tig mig portable fume extractor, which can capture fine dust particles with a particle size below 1, which is higher than the rate of electrostatic precipitators and high-pressure venturi precipitators. Dust properties. The rate of tig mig portable fume extractor is directly related to the size, weight, shape, electrostatic action and dust concentration of dust particles. It is reported that large particles, large gravity, irregular shape and obvious electrostatic action have a good dust removal rate.

How to improve the cleaning speed of tig mig portable fume extractor? Here, for you to explain in detail:

In the use of tig mig portable fume extractor, it is necessary to prevent the gas from cooling below the dew point in the bag room, especially when using tig mig portable fume extractor equipment under negative pressure.

Second, because its shell often has air leakage, so that the bag room gas temperature is lower than the dew point, the filter bag will be damp, resulting in dust is not loose, but sticky attached to the filter bag, the fabric hole blocked, resulting in ash failure, so that the dust collector pressure drop is too large, can not continue to operate, some can not dust paste bag.

A branch lift valve is closed, the filter air is cut off, and then the electromagnetic pulse valve is opened, the compressed air expands in the upper box in a short time, and rushes into the filter bag, so that the filter bag expands and deforms to produce vibration, and under the action of reverse airflow. Dust attached to the outer surface of the filter bag is stripped and dropped into the ash hopper.

Fourth, after the cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the chamber is restored to the filtering state. Cleaning each chamber in turn, from the beginning of room cleaning to the next cleaning for a cleaning cycle. The dust trapped by the filtration and ash cleaning work falls into the ash hopper, and then is centrally discharged by the ash discharging device at the mouth of the ash hopper.

With the extension of filtration time, the dust layer on the filter bag continues to accumulate, the resistance of the dust removal equipment continues to rise, when the resistance of the equipment rises to the set value, the cleaning device begins to clean the ash.

tig mig portable fume extractor equipment The equipment that separates the dust from the flue gas is called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be processed, the resistance loss of gas passing through the dust collector and the dust removal rate.

The price of dust collector, operation and maintenance costs, good and short service life and the difficulty of operation management are also important factors to consider its performance. Dust collector is a common facility in boiler and industrial production.
