Hong Tang Dust-removal System

Product Detail

A detailed description

Skills and characteristics of this industry is mainly reflected in the following aspects:

(1) biological Nano-film dust to be issued by the Ministry of science and technology, the Ministry of environmental protection included in the Repertoire of air pollution prevention and control technology

Bio-Nano-film dust suppression technology, bio-nano-film is spacing and nanometer dual-membrane in the ionosphere, can maximize the ductility of the water molecules, and strong adsorption of charge; bio-nano-membranes attached to the spray material surfaces can attract and agglomerating smaller particles of dust, its aggregated into larger particles like dust particles, deadweight increased subsidence.

(2) the clouds and dust was released by the Ministry of science and technology, the Ministry of environmental protection included in the Repertoire of air pollution prevention and control technology

Clouds and dust technology is atomized and ultrasonic atomized high pressure ion, can generate 1 µ m~100 µ m Super fine dry mist Super fine dry mist particles finer, fully increase the contact area with the dust particles, mist particles and dust particles collide and coalesce to form aggregates, aggregates grows heavier, until eventually settling, achieve the purpose of elimination of dust.

(3) wet dust collection are issued by the Ministry of science and technology, the Ministry of environmental protection included in the Repertoire of air pollution prevention and control technology

Wet dust collection technique is to absorb the dust in the air by pressure drop, centrifugal force and a water and dust-gas mixture under the double effect of dust; unique impeller key design provides a higher degree of efficiency. [1]

(4) the electrostatic precipitation technology at the mature stage, but the emission concentration to achieve new standards of control requirements

At present, the electrostatic precipitation technology has been developed, mainly technology has entered the international advanced level.

Electrostatic precipitation technology in high temperature flue gas treatment applications such as power plant is more mature. Restrictions due to the dust collection principle, the dust removal efficiency of electrostatic dust collection technology has greatly improved, new electrostatic precipitator systems can control the emission concentrations at about 100mg/M3. Meanwhile, the dust removal efficiency due to the influence of dust ratio resistance changes, in actual operation, burning fuels uncertainty working flue gas deviation from the design value parameters, resulting in dust control of discharge concentration is often far higher than the design value. Along with the increasing demand for pollution control of flue gas, the emission of fine dust are more stringent, electrostatic precipitation technologies are facing serious challenges.

(5) bag filter technology is in the development phase

Compared with electrostatic dust collection technology, bag-type dust collecting technology started late. Through the introduction of foreign advanced technology and digestion and absorption, bag-type dust collecting technology in China has made great progress, various bag filter technology is getting advanced and perfect and complete, filter technology, cleaning, parts have evolved, such as industry, part of bag-type dust collecting equipment performance has reached the international advanced level. By bag type dust filter the dust concentration in the exhaust gas, soot concentrations can reach 5mg/M3, and declining investment, operation and maintenance costs, prolongs the service life of the filter bag. With China's increasing demands on flue gas pollution control for bag filter technology has been widely used, are in a stage of rapid development.

(6) the changing bag and technology of electric-bag composite dust-is on the rise

With national on industrial flue gas pollution control requirements constantly improve, electrostatic dust technology faced with severe challenge, part original using electrostatic dust equipment of enterprise, because up not to emissions requirements, had to will electrostatic dust equipment transformation for bags type dust equipment, this way referred to for "electric modified bags"; while, consider to China existing high temperature industrial flue gas dust most using electrostatic dust equipment, has some early input larger, domestic part dust equipment host manufacturing enterprise used "electric bags composite type dust" Technology transforms the back end of electrostatic precipitator into bag filter, electrostatic precipitator for "electric-bag composite dust."
