Abstract
The utility model discloses a dedusting centrifugal fan. The dedusting centrifugal fan comprises a casing and a rotor and is characterized in that a dust separating grate, a dust collecting way and a dust discharging port are arranged on the casing. The dust separating grate is composed of a plurality of arc-shaped blades evenly fixed along the circumference of the casing. The dust collecting way and the dust discharging port are arranged in the fan casing, so that the dedusting effect of the fan is facilitated, air pressure loss is not caused, smoke in the dust collecting way can be utilized secondarily, and the dedusting centrifugal fan has the advantages of removing dust and saving energy.
Description
Technical field:
The utility model relates to a kind of dedusting centrifugal blower, belongs to the technological improvement of blower fan.
Background technique:
The existing matching used induced draught fan of medium small boiler, be generally centrifugal blower, this blower fan has housing and rotor, prismatic blade or backward bent vane are arranged on the rotor, housing is the spiral case of variable cross section, and this blower fan can only be provided by the mobile energy that provides of boiler smoke, and a large amount of dusts that carry in the flue gas then can not be separated and remove, remove then deduster of necessary series connection of these dusts, can increase the flow losses of flue gas like this.
The model utility content:
The purpose of this utility model is exactly the deficiency at prior art, and a kind of dedusting centrifugal blower is provided, and this blower fan has dedusting function, is applicable to boiler exhaust gas usefulness.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of dedusting centrifugal blower comprises housing and rotor, it is characterized in that: housing is provided with dust separation grid, collection grey-way and ash-discharge opening.The dust separation grid is made of many arc shaped blades of evenly fixing along the housing circumference.
Beneficial effect: the utility model is conducive to blower fan dedusting effect by the control of dust ash-exhausting device is set in Blower Housing, can't cause air loss, and the flue gas secondary in the collection grey-way can be utilized, and has the advantage of dedusting energy-saving.
