Description
Technical field
The utility model belongs to air inducing pipeline system regions, and in particular to a kind of recovery furnace air inducing system for effectively restraining surge
System.
Background technology
Air-introduced machine is widely used in the ventilation of factory, mine, tunnel, cooling tower, vehicle, ship and building, dust discharge and cold
But；The ventilation of boiler and industrial furnace and air inducing；Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance；Cereal
Dry and select and recommend；Inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc..The operation principle of air-introduced machine and the basic phase of turbocompressor
Together, only because gas flow rate is relatively low, pressure change is little, typically the change without the concern for gas specific volume, i.e., gas is made
For incompressible fluid processing.Surge is under a kind of damage that air-introduced machine is occurred when flow is reduced to a certain extent
Vibration, the generation of surge is relevant with the characteristic of fluid machinery and pipeline, and the capacity of pipe-line system is bigger, then surge is stronger, frequency
Rate is lower.The surge of fluid machinery can destroy the flowing law of machine interior media, produce mechanical noise, cause workpiece
Judder, accelerate bearing and sealing damage.When surge causes pipeline, machine and its basic resonance, it can also cause
Serious consequence.Induced draught system currently used in the market, greatly most without the function of restraining surge, have and restrain surge function
Also cost is very high for induced draught system, and needs to configure many circuit arrangements, repairs difficulty, and the vibrationproof of whole induced draught system
Effect is bad, and noise is very big under working condition.
Utility model content
The purpose of this utility model is：For supression surge effect set forth above is bad, cost is high, and vibrationproof is imitated
The problem of fruit is bad, and noise is very big under working condition, the utility model provide a kind of recovery furnace air inducing system for effectively restraining surge
System.
The technical solution adopted in the utility model is as follows：
A kind of recovery furnace induced draught system for effectively restraining surge, including casing, the intake stack that is connected on casing and go out
Wind pipeline and the blower motor being arranged on casing, by-pass line is connected between the intake stack and wind pipe, it is other
