Technical field
The utility model relates to a kind of deodorization apparatus of garbage incinerating power plant of garbage incinerating power plant, especially a kind of rubbish
The odour seal device of rubbish power generation by waste combustion factory centrifugal blower.
Background technique
Centrifugal blower is the principle that potential energy is converted to according to kinetic energy, is accelerated gas using high-speed rotating impeller, then
Slow down, change flow direction, kinetic energy is made to be converted into potential energy (pressure).In one-stage centrifugal blower, gas is from axially into impeller, gas
It is radially redirected when flowing through impeller, subsequently into diffuser.In diffuser, gas and changing flow direction and conduit section
Area increase makes flow slowing down, and this decelerating effect converts kinetic energy into pressure energy.Pressure, which increases, to be occurred mainly in impeller,
Secondary generation is in diffusion process.In Multi-stage centrifugal fan, next impeller is allowed airflow into return channel, generates higher pressure.From
Heart blower is widely used in the logical of factory, mine, tunnel, cooling tower, vehicle, ship and building in power plant's operation centrifugal blower
Wind, dust discharge and cooling；The ventilation of boiler and industrial furnace and air inducing.
Rubbish is generally filled in the operation of refuse-burning plant rubbish storage pond, is fermented so that water is filtered dry rubbish, rubbish
A large amount of biogas and hot gas are generated, during the fermentation to ensure plant environment odorless, MSW Incineration Plant garbage storing
Depositing pond generally maintains negative pressure to run, and to maintain garbage pool negative pressure, it is smelly that garbage burning factory generally uses centrifugal blower to extract garbage pool
Gas is sent into incineration furnace grate in the following, firing as rubbish using blower for (200 DEG C or so) after foul smell is heated by air preheater (steam)
Burn the dry wind and combustion air needed.
Problem is that garbage incinerating power plant First air generally passes through centrifugal blower and is drawn from garbage pool, is re-fed into rubbish and burns
Furnace is burnt as the combustion air of incineration firing.To guarantee rubbish storage pond negative pressure, centrifugal blower is divided into stationary part and rotation section
Point, stationary part refers mainly to blower pedestal, blade wheel chamber, bearing housing, and rotating part refers mainly to impeller, rotation axis and bearing.It is true
It protects blower to operate normally, must be provided with gap between rotation axis and blade wheel chamber.Under normal circumstances, blower high-speed motion rotates, whole
It is operation under positive pressure between a blade wheel chamber, and impeller internal is positive pressure, this results in the presence of the gap between blade wheel chamber and rotation axis
Air leakage point, garbage burning factory primary air fan (extracting garbage pool foul smell) are generally disposed at main building, and foul smell leakage influences rubbish and burns
Power plant workshop is burnt to carry out production strictly in line with rules and regulations environment.

Between running clearance is set, and described sealing sheath one end and blade wheel chamber seal the fixed other end and bearing housing housing seal is solid
It is fixed, effectively foul smell can be isolated with exterior space, prevent foul smell from coming up from the gap between blade wheel chamber and rotation axis, it is ensured that
The clean and tidy health of production environment.
The utility model solves the technical solution that is proposed of technical problem, a kind of garbage incinerating power plant centrifugal blower
Odour seal device, including motor, bearing housing, rotation axis, impeller, blade wheel chamber, pedestal, air entry, exhaust outlet, the bearing
Case, blade wheel chamber and motor are fixed on pedestal, and motor drives wheel rotation by rotation axis, and air enters leaf from air entry
Then engineer room is discharged from exhaust outlet, characterized in that sealing sheath is set between the blade wheel chamber and the bearing housing, it is described close
Closure covers that one end and blade wheel chamber seal fixed and the other end is fixed with bearing housing housing seal, the cylindrical knot of sealing sheath
Structure is simultaneously socketed in outside rotation axis, and running clearance is arranged between the sealing sheath inner wall and rotation axis.
The utility model preferred embodiment is that the sealing sheath is composed of upper tube half, lower tube half, will be close when installation
Closure covers upper tube half, lower tube half socket on the rotating shaft, then fixes upper and lower semicanal adhesion using alite paste and constitutes circular tube shaped
Structure, described sealing sheath one end and blade wheel chamber seal fixed and the other end is fixed with bearing housing housing seal.
The utility model preferred embodiment is that the running clearance in the sealing sheath between caliber and shaft is 10-20 milli
Rice.
The utility model preferred embodiment is that the wall thickness of the sealing sheath is 5-20 millimeters.
The utility model has the beneficial effects that the utility model proposes a kind of garbage incinerating power plant centrifugal blower deodorization
Sealing device, by the way that sealing sheath is arranged between blade wheel chamber and bearing housing, the cylindrical structure of sealing sheath is described close
Closure set is socketed in outside rotation axis, and running clearance, the sealing sheath are arranged between the sealing sheath inner wall and rotation axis
One end and blade wheel chamber seal fixed and the other end is fixed with bearing housing housing seal, can effectively by foul smell and exterior space every
From preventing foul smell from coming up from the gap between blade wheel chamber and rotation axis, it is ensured that the clean and tidy health of production environment.
