Description
Technical field
The present invention relates to a kind of wet dust separater.
Background technology
Wet dust removal utilizes cleaning solution (being generally water) fully to contact with dusty gas, grit is washed and makes the method for gas purification, current wet dedusting system, blower fan is the power source of air motion in whole system, but general blower fan does not play dedusting, and current wet dust removal need utilize the hole for water spraying on nozzle to spray High-Pressure Water to produce water smoke, the dust in dusty gas is removed by water smoke, this dust collection method is due to needs generation water smoke or moisture film, this just requires that the hole for water spraying on nozzle is very little, the aperture General Requirements of hole for water spraying is less than 1 millimeter, this just makes the more difficult processing of this hole for water spraying, and hole for water spraying easily blocks, and then cause equipment fault, and hydraulic pressure on nozzle is higher, so just make the energy consumption of booster pump higher, make use cost higher.
Summary of the invention
Technical problem to be solved by this invention is, a kind of better dust removal effect is provided, hole for water spraying be easier to processing and do not allow susceptible to plugging wet dust separater.
For solving the problems of the technologies described above, wet dust separater provided by the invention, it comprises an eccentric blower fan and a housing, this housing has an air inlet and a gas outlet, this eccentric blower fan has air entry and a tangential exhaust outlet of an axis, the gas outlet of this housing is connected with the axial air entry of this eccentric blower fan, a water pipe is provided with in this housing, the end of this water pipe is provided with a nozzle, the hole for water spraying of this nozzle near and towards the air entry of eccentric blower fan, the aperture of hole for water spraying is 10 ~ 20 millimeters.
After adopting above structure, the present invention compared with prior art, has following advantage:
When the present invention uses, then water in water pipe enter in eccentric blower fan from the hole for water spraying ejection of nozzle, superfine water smoke and moisture film is formed under the effect of eccentric fan blade High Rotation Speed, dusty gas enters into after in eccentric blower fan from air entry, in the strong turbulence flow field that eccentric blower fan produces, dust in dusty gas mixes with water and is thrown on the inwall of eccentric blower fan, so just dedusting is carried out to dusty gas, good dedusting effect, and due to hole for water spraying ejection water do not need produce water smoke, what make the aperture of the hole for water spraying on nozzle not need to do is too little, this hole for water spraying is made to be easier to processing, and hole for water spraying is not easy blocking, equipment is made to be not easy fault, make the hydraulic pressure on nozzle not need too high simultaneously, booster pump is not needed to carry out supercharging, make cost lower.
