The purpose of the present invention can be achieved through the following technical solutions：
A kind of air intake equipment of gas fired-boiler, for gas fired-boiler, including controller and it is connected respectively with controller
Temperature inductor and two frequency conversion fans with model, two frequency conversion fans are symmetricly set on the ground of gas fired-boiler both sides,
Connected respectively by the combustion chamber of ajutage and gas fired-boiler, temperature sensor is arranged in the combustion chamber of gas fired-boiler, is controlled
Device receives the air force of signal two frequency conversion fans of synchronous adjustment of temperature sensor.
Preferably, magneto-rheological vibration damper is provided between described frequency conversion fan and ground.
Preferably, described magneto-rheological vibration damper includes magnetic rheology elastic body, power supply and multiple electromagnet, described magnetic current
The top for becoming elastomer is provided with multiple grooves arranged side by side, and an electromagnet is equipped with each groove, and the depth of groove is more than electricity
The thickness of magnet, each electromagnet are powered by power supply, and are communicated to connect with controller, when power supply is powered, two neighboring electromagnet
In there is a natural attraction between the sexes.
Preferably, the bottom of described frequency conversion fan is connected with the top of base, described base and magnetic rheology elastic body
Vulcanization connection.
Preferably, described ajutage is L-shaped, and bending place is provided with elbow.
Preferably, described frequency conversion fan is three-phase alternating current frequency conversion fan.
Compared with prior art, the invention has the advantages that：
(1) vibrating noise pollution is reduced：, should be by the way that frequency conversion fan be arranged on compared with mounting means at the top of general use

Need to climb, be operated on ground, it is easy to operate, reduce manpower.
(3) whole air inlet system is optimized, blast pipe structure optimization, makes whole steam generator system improved efficiency：Pass through two
The common air blast of frequency conversion fan, the load of each blower fan being reduced, blowing efficiency is high, and reaction is fast, and due under blower fan underload
Vibration and noise are small, therefore also contribute to noise-and-vibration-reduction.
(4) by setting magneto-rheological vibration damper so that damping is adjustable, when fan delivery increases, vibration aggravation, leads to
The electric current for crossing controller control electromagnet increases, and the magnetic field in magnetic rheology elastic body becomes strong, and resistance of shock absorber becomes big, to frequency conversion wind
The support enhancing of machine, help to reduce the vibration of frequency conversion fan, reduce noise.
(5) by groove, avoid electromagnet and contacted with the hard of variable-frequency motor, improve effect of vibration and noise reduction.
(6) top of the base of frequency conversion fan and magnetic rheology elastic body vulcanization connection, increases the contact area of the two, has
Beneficial to raising effect of vibration and noise reduction.
