Description
Technical field
The utility model relates to a kind of booster expansion turbine, especially relates to a kind of booster expansion turbine that is used for chemical recovery unit.
Background technique
The working procedure of turbo-expander is a kind of adiabatic expansion process; Obtaining low temperature is its topmost effect; Inflation process also is the externally thermal procession of acting simultaneously; Obtaining low temperature then is the necessary condition of separating poisonous and hazardous precious industrial chemicals in the working medium, and externally the energy in the working medium has then been reclaimed in work done, and turbo-expander has been brought into play irreplaceable effect in the chemical industry tail gas recovering device.
It is big that tail gas in the general chemical industry has a flow, the characteristics that temperature is high, in the chemical industry flow process when tail gas is discharged; Be discharged to great amount of high-temperature gas in the atmosphere; Also in discharging gas, take simultaneously a certain amount of poisonous and hazardous precious industrial chemicals (like aromatic hydrocarbons etc.) out of,, not only polluted atmosphere to toxic and harmful if these tail gas are discharged naturally in atmosphere; Very big to the health infringement, but also can waste great amount of heat and precious industrial chemicals.
Use common turbo-expander; There is a large amount of waste heat overbottom pressure waste gas in the chemical-process; These gases are large-minded, the waste heat overbottom pressure; Usually often directly discharge as waste gas, this not only wastes energy, but also drains the material gas of the preciousness of poisonous and harmful befouling environment in this waste gas as waste gas.As also reclaiming part energy, utilize the cold that decompressor produces can also be simultaneously the useful condensation of gas in addition Separation and Recovery of getting off through common turbo-expander.
Summary of the invention
The utility model provides a kind of booster expansion turbine that is used for chemical recovery unit to the deficiency of existing technology.
For realizing above-mentioned purpose; The utility model can be taked following technical proposals: a kind of booster expansion turbine that is used for chemical recovery unit; Comprise body, volute of blower, blower fan vaneless diffuser, blower fan import convergence pipe, booster fan wheel, decompressor spiral case and decompressor active wheel; Said body left side is provided with volute of blower, and the volute of blower top is provided with the blower fan outlet, and the right side is provided with the decompressor spiral case; Decompressor spiral case top is provided with expander inlet, and said blower fan outlet is communicated with the turbo-expander import; Be provided with main shaft in the said body, there is bearing at the main shaft two ends, and the bearing top is provided with the bearing oil feed pipe road that links to each other with bearing, and the body top is provided with the lubricant oil ventilating cover.
As preferably, said bearing can be sliding bearing or rolling bearing.
As preferably, described booster expansion turbine
System In be provided with anti-surge installation.
As preferably, be provided with blower fan side thermal baffle between said body and the volute of blower.
As preferably, be provided with the expander side thermal baffle between said body and the decompressor spiral case.
The beneficial effect of the utility model is: have surplus
Heat The tail gas of overbottom pressure is not directly to get into the expander inlet pipeline; Carry out supercharging but be introduced into the booster fan ingress; This is after the inlet ductwork that the intensification back tail gas that boosts of supercharging gets into decompressor again; At this moment tail gas because of supercharging after the energy head of tail gas be greatly improved, wherein the power of pressure-increasing machine is by externally acting and obtaining in the other end decompressor impeller inflation process; And the supercharging result has exactly improved a step to the external acting of decompressor, generally can improve 1.2～1.3 times refrigerating capacity.So after having adopted booster expansion turbine, refrigerating capacity will produce better economic and social benefit after improving.
