Industrial dust removal equipment, also known as industrial dust collector, can separate industrial dust from the flue gas produced by industrial production. The performance of different industrial dust removal equipment is definitely different, and the sales of dust removal can be calculated based on the amount of gas that can be handled, the resistance loss of the gas passing through the industrial dust removal equipment, and the efficiency of the dust removal. As for the price of industrial dust removal equipment, operation and maintenance costs, the length of service life and the ease of operation and management are also very much related to performance, while the principle of industrial dust removal equipment is the basis, the next to introduce the principle of industrial dust removal equipment.
Principle of industrial dust collector equipment:
1, biological nano-film dust suppression: biological nano-film dust suppression technology, biological nano-film is a layer spacing to the nanometer level of the double ionized layer of the membrane, can maximize the water molecules of the extensibility, and has a strong charge of adsorption; will be sprayed on the surface of the material biological nano-film, can attract and agglomerate the small particles of dust, make it aggregated into large particles. It can attract and agglomerate small particles of dust, make it polymerize into large granular dust particles, increase self-weight and settle; the dust removal rate of this technology can reach up to more than 99%, and the average operating cost is 0.05~0.5 yuan/ton.
2, cloud dust suppression: cloud dust suppression technology is through high-pressure ion atomization and ultrasonic atomization, can produce 1μm ~ 100μm of ultra-fine dry fog; ultra-fine dry fog particles are fine and dense, to fully increase the contact area with the dust particles, the water mist particles and dust particles collision and cohesion, the formation of agglomerates, agglomerates continue to get bigger and heavier until the final natural settlement, to achieve the purpose of eliminating dust; produced dry fog particles, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30%, 30% and 30%. The dry fog particles produced, 30% to 40% of the particle size of 2.5μm or less, the prevention and control of fine particle pollution of the atmosphere is obvious.
3, wet dust collection: wet dust collection technology through the pressure drop to absorb the air attached to the dust, in the centrifugal force as well as the mixing of water and dust gas under the dual role of dust removal; unique impeller and other key design can provide higher dust removal efficiency. It is suitable for bulk material production, processing, transportation, loading and unloading, such as mines, construction, quarries, stockyards, ports, thermal power plants, iron and steel mills, waste recycling and disposal.
4, bag dust removal: dust collector is mainly composed of dust hopper, filtering chamber, clean gas chamber, bracket, lifting valve, blowing ash removal device and other parts. When working, the dusty gas enters into the dust hopper by the air duct. Large particles of dust fall directly into the bottom of the dust hopper, smaller dust with the airflow turns up into the filter room, and is blocked on the outside surface of the filter bag, the purified flue gas into the bag, and through the bag mouth and the clean air chamber into the air inverted, discharged by the exhaust port. With the continuous filtration, the dust on the outside surface of the filter bag increases continuously, and the resistance of the equipment rises. When the equipment resistance rises to a certain value, should be cleaned operation, remove the dust on the surface of the filter bag.
5, electrostatic dust removal: a gas dust removal method. Dust-containing gas through the high-voltage electrostatic field is electrically separated, dust particles and negative ions combined with negatively charged, tend to the anode surface discharge and deposition. In metallurgy, chemistry and other industries used to purify the gas or recovery of useful dust particles. The use of electrostatic field to make the gas ionization so that the dust particles charged adsorption to the electrode dust collection method. In the strong electric field air molecules are ionized into positive ions and electrons, the electrons run to the positive pole in the process of encountering dust particles, so that the dust particles are negatively charged adsorption to the positive electrode is collected. Commonly used in coal-fueled factories and power stations to collect coal ash and dust in the flue gas. In metallurgy, it is used to collect the oxides of tin, zinc, lead, aluminum and so on.
The above is the content of the principle of industrial dust collector equipment, industrial dust collector equipment is used in many industrial places, is a necessary equipment in industrial production, and industrial dust collector equipment operating pressure is not fixed, usually according to the device before and after the industrial dust collector equipment and the static pressure value of the fan is related to the other, but also with the installation location has a lot to do with the design of the industrial dust collector equipment pressure-resistant value on the Its performance has a great impact, which can also be understood in the principle of industrial dust collector equipment.
