Abstract
The utility model discloses a three-dimensional impeller centrifugal compressor which comprises a plurality of compression sections, wherein an inter-section cooler is arranged between every two compression sections; the inter-section cooler comprises a cylinder; the two ends of the cylinder are abutted with end sockets; a heat exchange tube and a baffle are mounted in the cylinder; a cooling water inlet and a cooling water outlet are formed on the end sockets, respectively; a gas inlet and a gas outlet are formed on the cylinder; and the gas inlet is formed at the end close to the cooling water inlet. The three-dimensional impeller centrifugal compressor is divided into the plurality of compression sections, and the inter-section cooler is arranged between every two compression sections; high-temperature gas exhausted by the previous compression section enters the next compression section to be compressed after being cooled in the inter-section cooler; and in this way, the purposes of saving power and safe operation of the compressor can be achieved. Besides, the number of the compression sections is determined according to the gas pressure.
Description
Technical field
The utility model relates to a kind of 3 d impeller centrifugal compressor.
Background technique
Centrifugal compressor is a kind of rotating vanes gas compression machinery, and gas is sucked by induction chamber, through impeller gas is done work; Gas pressure, speed, temperature are improved, and then through Diffuser, speed reduces; Change the pressure ability into by kinetic energy, pressure is improved, flow into the bend and the return channel of guiding again; Make gas get into the next stage compression, the pressurized gas that last final stage is come out are discharged along spiral case and pneumatic tube.
The pressure ratio of centrifugal compressor even can reach 30 or higher generally on 3, for high like this pressure ratio; Temperature after the compression can be very high; Know that from the compressed action principle isothermal compression is to economize merit most, if do not cool off in the compression process; Not only make the many wasted works of compressor, and also very unfavorable to the running of compressor.
The model utility content
The purpose of the utility model is to provide the 3 d impeller compressor of a kind of province merit, safety.
The described 3 d impeller compressor of the utility model, it comprises a plurality of compressing sections, between each compressing section, disposes intersegmental cooler; Said intersegmental cooler comprises cylindrical body; The two ends butt joint end socket of cylindrical body is installed heat exchanging tube, deflection plate in the said cylindrical body, cooling water intake and coolant outlet are set respectively on the said end socket; Gas access and gas outlet are set on the cylindrical body, and the gas access is arranged on by the cooling water intake end.
The two ends of said cylindrical body are provided with tube sheet respectively and fix said heat exchanging tube.
The utility model is divided into a plurality of compressing sections with compressor; Between each compressing section, dispose intersegmental cooler; Utilize the cooling water in the heat exchanging tube to come cooled gas; The high-temperature gas that previous compressing section is discharged gets in the housing of intersegmental cooler and gets into the compression of next compressing section again after the cooling, so just can reach province's merit and compressor purpose of safe operation.How much confirming of compressing section according to the size of gas pressure.
Description of drawings
Fig. 1 is the preferred embodiment structural representation of the utility model.
Fig. 2 is the structural representation of the intersegmental cooler of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2, the preferred embodiment of the utility model is divided into two compressing sections with compressor, configuration intersegmental cooler 3 between first compressing section 1 and second compressing section 2.Intersegmental cooler 3 comprises cylindrical body 31, and heat exchanging tube 32, deflection plate 33 are installed in the cylindrical body 31, and the two ends of cylindrical body 31 are provided with tube sheet 34 and fix heat exchanging tube 32, tube sheet 34 outer butt joint end sockets 35, and deflection plate 33 is provided with perpendicular to cylindrical body 31; On the end socket 35 in left side cooling water intake 36 is set, on the end socket 35 on right side coolant outlet 37 is set, the gas access 38 and the gas outlet 39 of cylindrical body 31 bottoms dock with the exhaust outlet 11 of first compressing section, the gas access 21 of second compressing section respectively.Cooling water is walked in the heat exchanging tube 32 of intersegmental cooler 3, and gas is walked in the housing of intersegmental cooler 3, carries out heat exchange between the two.
Gas gets into 1 back, first compressing section through 12 pairs of gas actings of impeller; Pressure, speed, the temperature of gas are improved; Through diffusion the speed of gas is reduced then, change the pressure ability into, the pressure of gas is improved by kinetic energy; After this high temperature and high pressure gas that comes out from the exhaust outlet 11 of first compressing section 1 gets into intersegmental coolers 3 coolings from the high-temperature gas inlet 38 of intersegmental cooler 3; Come out to get into second compressing section 2 from its cryogenic gas outlet 39, repeat acting and the diffusion of a compressing section to gas, last pressurized gas are discharged along spiral case and pneumatic tube.
How much confirming of compressor compresses section according to the size of gas pressure.
Claims (2)
1. 3 d impeller centrifugal compressor, it is characterized in that: it comprises a plurality of compressing sections, between each compressing section, disposes intersegmental cooler; Said intersegmental cooler comprises cylindrical body; The two ends butt joint end socket of cylindrical body is installed heat exchanging tube, deflection plate in the said cylindrical body, cooling water intake and coolant outlet are set respectively on the said end socket; Gas access and gas outlet are set on the cylindrical body, and the gas access is arranged on by the cooling water intake end.
2. 3 d impeller centrifugal compressor as claimed in claim 1 is characterized in that: the two ends of said cylindrical body are provided with tube sheet respectively and fix said heat exchanging tube.
