A little corrosive gas, exhaust gas need just arrange in addition after treatment.Usual exhaust gas passes through washing, purifying equipment in centrifugal blower
It is handled.And in practical fan operation, most exhaust gas are discharged from gas outlet after processing, but have a little exhaust gas due to machine
The non-hermetic of shell, escapes from the aperture between casing or high pressure draught is to the inertia at low pressure, in casing internal
Axle envelope, Chang Liuyou portions at impeller corrode instrument.
Invention content
The purpose of the present invention is to provide a kind of waste gas collection devices of centrifugal blower, are carried out to the structure of centrifugal blower
It improves, reduces the uncontrollable discharge of exhaust gas, and the apparatus structure is simple, easy for assemble or unload, service life is long.
To achieve the above object, the present invention provides the following technical solutions:A kind of waste gas collection device of centrifugal blower, including
Centrifugal blower, gas sampling cover and gas-guide tube;The centrifugal blower includes Blower Housing, the air inlet being set on shell and outlet air
Mouthful, impeller and bearing in shell provide the pedestal of the motor and support wind turbine of kinetic energy to centrifugal blower;Bearing and motor it
Between shaft on gas sampling cover is installed, the Blower Housing is arranged in gas sampling cover, and air inlet and air outlet are passed through and received
Collect cover shell;Described gas-guide tube one end is by the way that on flanged joint gas sampling cover, the other end is connect with air inlet duct, described to lead
Tracheal strips have one-way guide flow structure, and electric air pump is provided on gas-guide tube;
Further, the one-way guide flow structure includes conical pipe, two shrapnels and the film for being located at shrapnel top;
Further, the conical pipe butt end is fixed on air guide inside pipe wall, and shrapnel is set in the both sides of conical pipe;
Further, the shrapnel is the small flat plastic plate of density;
Further, the gas sampling cover is fixed by the machine screws on centrifugal blower, gas sampling cover
Sealing material is filled between shaft;
Further, the air inlet is equipped with sealing ring between air outlet and collecting hood shell, to ensure gas sampling
Leakproofness in cover.
The beneficial effects of the utility model are:
1. the Blower Housing of the utility model is arranged in gas sampling cover, air inlet and air outlet pass through outside collecting hood
Sealing ring is equipped between shell and collecting hood shell, and gas sampling cover is mounted on centrifugal blower, is filled between shaft close
Closure material thereby guarantees that the leakproofness in gas sampling cover, avoids exhaust gas excessive from junction between casing, reduces the nothing of exhaust gas
Tissue discharge;
2. diversion pipe of the setting with one-way guide flow structure, will give up between the gas sampling cover and air inlet of the utility model
Exhaust gas is overflowed in gas collecting hood, and air inlet is extracted into again to purified treatment in wind turbine by air pump;
3. the one-way guide flow structure of the utility model is respectively provided at conical pipe both sides by the way that conical pipe is arranged in diversion pipe
Two shrapnels and be located at the film on shrapnel top, make exhaust gas only it be allowed to flow in one direction, and prevent its negative direction stream
It is dynamic.
Description of the drawings
Fig. 1 is the surface structure schematic diagram that the utility model is implemented.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of waste gas collection device of centrifugal blower, including centrifugal blower 1, gas sampling cover 2 and air guide
Pipe 3;The centrifugal blower 1 includes Blower Housing 4, the air inlet 5 and air outlet 6 being set on shell 4,7 He of impeller in shell
Bearing 8 provides the pedestal 10 of the motor 9 and support wind turbine of kinetic energy to centrifugal blower;In shaft between bearing 8 and motor 9
Gas sampling cover 11 is installed, the Blower Housing 4 is arranged in gas sampling cover 11, and air inlet 5 and air outlet 6 pass through collecting hood
11 shells;3 one end of the gas-guide tube is connected by flange 12 on gas sampling cover 11, and the other end is connect with 5 pipeline of air inlet, institute
Stating has one-way guide flow structure 13 in gas-guide tube 3, electric air pump 14 is provided on gas-guide tube 3;The one-way guide flow structure 13 includes
Conical pipe 01, two shrapnels 02 and the film 03 for being located at shrapnel top;01 butt end of the conical pipe is fixed on 3 inner wall of gas-guide tube,
Shrapnel 02 is set in the both sides of conical pipe 01;The shrapnel 02 is the small flat plastic plate of density;The gas sampling cover 11
It is fixed by the machine screws on centrifugal blower, sealing material 15 is filled between gas sampling cover and shaft;The air inlet
Mouthfuls 5, sealing ring is equipped between 11 shell of air outlet 6 and collecting hood, to ensure the leakproofness in gas sampling cover.
In this example, Blower Housing is arranged in gas sampling cover, and air inlet and air outlet pass through collecting hood shell, and
Sealing ring is equipped between collecting hood shell, and gas sampling cover is mounted on centrifugal blower, and sealing material is filled between shaft
Material, thereby guarantees that the leakproofness in gas sampling cover, avoids exhaust gas excessive from junction between casing, reduce the inorganization of exhaust gas
