Description
Technical field
This utility model belongs to the technical field of centrifugal compressor, that is, provide it is a kind of with parallel dry gas seals it is multistage from
Heart compressor.
Background technology
When existing centrifugal compressor adopts multilevel hierarchy, air intake duct and diffuser phase between active wheel (impeller), are adopted
Even.Gas is compressed under the influence of centrifugal force as the high speed of active wheel rotates after entering compressor, and its speed and temperature are all
Can improve a lot.Diffuser is divided into has leaf and without two kinds of leaf, and they are the circular passages being made up of two side walls, work as gas
During by diffuser, it can make the kinetic energy of gas be converted into pressure energy, and now the temperature of gas rises, and speed declines.For many
For level centrifugal compressor, with the increase of series, temperature rise is also just more notable.
The at present centrifugal compressor applied by major part petrochemical enterprise has the compressor of horizonally split formula, cartridge type compression
Machine (i.e. vertical subdivision), Axial Flow Compressor etc., the gas of the compressor conveying of these species is entered from the import of one end
Enter in compressor, exported from the outlet of the other end after the supercharging of rotor, entered in the process pipelines of user, even if having point
For two sections or three sections of compressor, it is that gas temperature is too high, passes the gas through the effect that cooler reaches cooling, again returns to pressure
In contracting machine, pressure is improved.
Chinese invention patent application case CN102434491A discloses one kind《Centrifugal compressor》, described vane diffuser
Stator it is identical by trailing edge radius and the different long and short stator of length is constituted, at least configure a piece of between adjacent long stator
Short-range missile leaf, using the rectified action of short-range missile leaf, improves the performance of compressor.
Chinese patent CN1015489B discloses one kind《Multistage centrifugal compressor》, it is characterised in that：Compressor each leaf
Wheel and connected diffuser composition one-level, at least four centrifugal rotors of compressor and at least four lead vane type diffuser
(i.e. vane diffuser).The stator leading-edge radius for leading previous diffuser in vane type diffuser told and rotor outlet radius it
Than the same ratio more than latter diffuser, and latter diffuser is close to the more described previous diffuser of discharge side.Except
At different levels outer described in vane type diffuser with leading, also at least one-level is without stator diffuser.As the rotation in diffuser takes off
Sulfur is produced in the backflow band that backflow develops and rotates in being formed in diffuser, and leads vane type diffuser by without stator
Diffuser starts to occur the inner side at backflow position and arranges stator leading edge, the effect with anti-backflow, thus, one opening in return channel
The backflow for beginning to occur is suppressed, and also avoids to rotate the generation of desulfurization, such that it is able to make compressor reach very high efficiency,
And can work in wider scope.
Chinese invention patent application case 20101025253.5 is disclosed《A kind of compression of the coaxial eccentricity with intercooler
Machine》, from the point of view of its structural representation, it is provided with a conduct in addition between two cylinder bodies of coaxial eccentricity compressor
Between cooler sealing container.This not only increased the cost of equipment, and the compressed gas through intercooler are passing through
Next stage cylinder is that temperature can also rise.
The starting point of above-mentioned all inventions all focuses on diffuser, reduces the first-class several aspects of temperature of compressed gas, so
And, the sealing property at the even more important two ends for being exactly compressor in centrifugal compressor, when compression is air, sealing it is tight
Property but there is no so much requirement, air be leaked to it is outer there is no any injury in the face of people, however, present petrochemical industry row
The gas compressed in industry is all harmful gas, once reveal to produce irremediable consequence.To sum up these are exactly
The starting point of our research work.

(1) housing of compressor is divided into upper and lower two housings from the horizontal plane of rotating shaft, and upper shell is same by the seal at two ends
Lower casing body phase is fixed；
(2) part such as impeller, spacer, balancing frame, thrust disc is arranged on main shaft an important portion for forming compressor
Part rotor, rotor are placed on lower house by bearing and bearing block；
(3) space of placement dry gas seals is provided with the seal at the two ends of compressor, installed above parallel dry
Hermetic seal.
The impeller of centrifugal compressor of the present utility model uses rustless steel double shrouded wheel, and blade is using palintrope structure
Blade shape, compared with the unshrouded impeller of other products, the whole efficiency of unit has greatly improved.
