What are the purification methods of dust-free workshop purification project? Ed Purification summarizes the following aspects: different ways of purification have their own advantages and disadvantages. Owners can choose according to the actual situation.
1. Physical Purification Method:
1. Adsorptive filtration-activated carbon is a porous carbon-containing substance. It has highly developed porous structure. The porous structure of activated carbon provides a large amount of surface area for it and can fully contact with gas (impurities), thus giving activated carbon its unique adsorption performance, making it very easy to achieve the purpose of absorbing and collecting impurities. Like magnetism, all molecules have mutual attraction.
2. Mechanical filtration - HEPA network HEPA (High efficiency particulate air filter), which means that the effective rate of HEPA standard filter is 99.998% for 0.3 micron. The characteristic of HEPA network is that air can pass through, but small particles can not pass through. The HEPA filter consists of a stack of continuously folded sub-glass fiber membranes, forming a wavy gasket for placing and supporting the filter boundary.
2. Electrostatic type:
Working Principle: The working principle of high voltage electrostatic adsorption dust removal is adopted. Electrostatic type is the working principle of high voltage electrostatic adsorption dust removal. Under the action of high voltage electrostatic field, the cathode wire in the electrostatic field produces a large number of negative ions in the corona layer. Under the action of the electrostatic field, the negative ions continuously move towards the anode. When dust in the air passes through the electric field, it is charged by the collision zone of negative ions. The charged dust is also acted by the electrostatic field, which moves towards the anode (dust collector) and releases the charge after reaching the anode. Disadvantages: Dust removal (not toxic gas removal), lower efficiency than mechanical, slow, and easy to produce ozone, this model was rated the worst purifier in the U. S. market.
3. [Other Purification Ways]
1. Washing method
Using the principle of siphon and centrifugation, the purifier mixed with water is sucked into the suction pipe of the lower part of the coaxial centrifugal turbine on the base of the motor through the principle of siphon. The purifier mixed with water is sprayed into the bottle gallbladder to form a layer of water film by using the principle of centrifugation. The dust and bacteria in the air are sucked into the water. www.hnjhgc.com will pass through the net at the same time. The converted air is blown into the room, quickly and effectively removing toxic organisms, dust, smoke, odor, viruses and so on, and generating a large amount of fresh oxygen.
2. Negative Ion Method
When the Hydroxyl Anion contacts with the harmful gas floating in the air, it can reduce the reactive oxygen species (oxygen free radicals) produced by pollutants, nitrogen oxides and cigarettes from the atmosphere, reduce the harm of excessive reactive oxygen species to human body, neutralize the positive air dust and settle after no charge, so that the air can be purified.
