Biological nano-film dust suppression technology, biological nano-film is a double-layer ionospheric film with nano-layer spacing, which can maximize the ductility of water molecules and has strong charge adsorption; Spraying biological nano-film on the surface of the material can attract and condense small particle dust, which will be polymerized into large particle dust, which will increase its own weight and settle; The highest dust removal rate of this technology can reach above 99%, and the average operating cost is 0.05~0.5 yuan/ton.
(2) Cloud dust suppression technology
Cloud dust suppression technology can produce ultra-fine dry fog of 1 micron ~ 100 micron through high-pressure ion atomization and ultrasonic atomization. Ultra-fine dry mist particles are fine, which fully increases the contact area with dust particles, and the water mist particles collide with dust particles to form aggregates, which become bigger and heavier until they finally settle naturally, thus achieving the purpose of eliminating dust; 30%~40% of dry fog particles produced are below 2.5um, which has obvious prevention and control effect on atmospheric fine particle pollution.
(3) Wet dust removal technology
Wet dust removal technology absorbs the air attached with dust through pressure drop, and removes dust under the dual effects of centrifugal force and mixing of water and dust gas; Unique impeller and other key designs can provide higher dust removal efficiency.
(4) Bag dust removal
Filtration of dusty gas by fiber fabric. When the dusty gas enters the bag filter, the dust with large particles and heavy proportion settles down and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is retained, so that the gas is purified.
(5) electrostatic dust removal technology
Dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field, and dust particles and negative ions are negatively charged, and then tend to discharge and deposit on the anode surface. Electrostatic field is used to ionize gas, so that dust particles are charged and adsorbed on electrodes. In the strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are adsorbed by the negative electrode to the positive electrode and collected.
