Abstract
A kind of single-stage high-speed SO2 centrifugal blower sealing device, is mainly made of three-dimensional flow impeller, back shroud, stainless steel seal, high speed shaft；It is characterized in that three-dimensional flow impeller is installed on high speed shaft；Stainless steel seal is locked on back shroud by hexagon socket head cap screw, is provided with O-ring seal between stainless steel seal and back shroud；Height stainless steel seals tooth and end face seal tooth on stainless steel seal, and height stainless steel seals tooth and diameter of axle tongue and groove, and successively height plug-in type cooperates, and end face seal tooth and three-dimensional flow impeller back plan cooperate；In summary it is formed by a kind of SO2 centrifugal blower sealing device.The utility model is that a kind of structure is simple, the good single-stage high-speed SO2 centrifugal blower sealing device of sealing effect.
Description
Technical field
The utility model relates to chemical industry SO2 waste gas recovery technology, especially suitable for delivery high-pressure SO2 gas from
The sealing of heart air blower is used.
Background technique
Due to great attention of the country to environmental protection in recent years, a large amount of SO2 gas is formed after boiler combustion and is forbidden to big
Gas discharge, for China's chemical industry to sulfuric acid industry demand, is now recycled SO2 exhaust gas, prevents from being discharged into atmosphere, but be directed to
The device of SO2 waste gas recovery now need to carry out pressurized delivered for SO2 exhaust gas, and increased pressure is higher, to delivery high-pressure
The centrifugal blower seal request of SO2 gas is very high, and there can be no external leakage phenomenons.
Utility model content
The utility model can effectively solve above-mentioned technological deficiency, provide that a kind of structure is simple, and the good single-stage of sealing effect is high
Fast SO2 centrifugal blower sealing device.
To achieve the above object, the technical solution adopted in the utility model is that a kind of single-stage high-speed SO2 centrifugal blower is close
Seal apparatus is mainly made of three-dimensional flow impeller, back shroud, stainless steel seal, high speed shaft；It is characterized in that three-dimensional flow impeller
It is installed on high speed shaft, stainless steel seal is locked on back shroud by hexagon socket head cap screw, in stainless steel seal and rear cover
O-ring seal is provided between plate；Height stainless steel seals tooth and end face seal tooth on stainless steel seal, and height is stainless
Steel seals tooth and diameter of axle tongue and groove, and successively height plug-in type cooperates, and end face seal tooth and three-dimensional flow impeller back plan cooperate, comprehensive
It closes to state and is formed by a kind of SO2 centrifugal blower sealing device.
Due to the adoption of the above technical scheme, the utility model ensure that SO2 exhaust gas is centrifuged through single-stage high-speed SO2 well
After air blower pressurization, high speed shaft seal position detection finds the basic No leakage of SO2 gas, and sealing effect is very good, passes through
Return-air hole accesses the centrifugal blower entrance negative pressure area single-stage high-speed SO2 and the outermost nitrogen charging hole nitrogen charging of seal, hinders well
Broken the external leakage of SO2 gas.
Detailed description of the invention
Fig. 1 is a kind of single-stage high-speed SO2 centrifugal blower sealing device schematic diagram of the utility model；
In figure: 1, three-dimensional flow impeller；2, back shroud；3, O-ring seal；4, hexagon socket head cap screw；5, return-air hole；6, stainless
Steel seal；7, high speed shaft；8, diameter of axle tongue and groove；9, height stainless steel seals tooth；10, nitrogen charging hole；11, end face seal tooth.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing, not to the limitation of its protection scope.
A kind of single-stage high-speed SO2 centrifugal blower sealing device, mainly by three-dimensional flow impeller (1), back shroud (2), no
It becomes rusty steel seal (6), high speed shaft (7) composition；It is characterized in that three-dimensional flow impeller (1) is installed on high speed shaft (7)；Stainless steel is close
Envelope body (6) is locked on back shroud (2) by hexagon socket head cap screw (4), is set between stainless steel seal (6) and back shroud (2)
It is equipped with O-ring seal (3)；Height stainless steel seals tooth (9) and end face seal tooth (11) on stainless steel seal (6), high
Successively height plug-in type cooperates low stainless steel sealing tooth (9) and diameter of axle tongue and groove (8), end face seal tooth (11) and three-dimensional flow impeller
(1) back plan cooperates；In summary it is formed by a kind of SO2 centrifugal blower sealing device.It is sealed by height stainless steel
Successively height plug-in type cooperates for tooth (9) and diameter of axle tongue and groove (8), end face seal tooth (11) and three-dimensional flow impeller (1) back plan
The flow and pressure of the good SO2 gas leakage that decayed of cooperation.Again by being provided with return-air hole on stainless steel seal (6)
(5), nitrogen charging hole (10) structure.Its high speed shaft seal position detection finds the basic No leakage of SO2 gas with this structure, close
It is very good to seal effect, the centrifugal blower entrance negative pressure area single-stage high-speed SO2 is accessed by return-air hole and seal is outermost fills
Nitrogen hole nitrogen charging, has blocked the external leakage of SO2 gas well, and structure is simply easily assembled and disassembled.
Therefore, the utility model is that a kind of structure is simple, and the good single-stage high-speed SO2 centrifugal blower of sealing effect seals dress
It sets.
