The pipeline wheel booster ventilator of the present invention is quite different from the existing centrifugal, axial, screw, screw compressor and gas compressor structural principles, and the terminology and function of structural components are very different from those currently popular. For the sake of convenience and clarity, there are several terms that are explained here:

The radial part of the air duct near the end of the duct is the root of the duct, referred to as the duct root. The radial end of the duct is called the top of the duct, which is referred to as the top of the duct; the part of the duct close to the root of the duct is called the lower part or the bottom of the duct. The top of the duct near the top of the duct is called the upper part of the duct.

The outer edge of the duct wheel is the radial edge of the duct wheel. The axial side edge of the duct wheel is called the axial edge of the duct wheel. The axial edge of the duct wheel is divided into the axial edge of the duct wheel and the axial edge of the duct wheel. The side wall of the rotor center axis is the axial side wall of the duct wheel, and other related parts of the body are called and so on.

The side of the air inlet end of the whole body is the front side or the front or the front side, and the other side opposite to the front side is the rear side or the rear or the rear. The side of the air duct side facing the front side of the body is the front side, and the side facing the rear side of the machine body is the rear side.

The direction of rotation of the rotor is circumferential, and the direction of rotation of the forward rotor is forward or circumferentially forward, and the direction of rotation of the rotor is rotated rearward or circumferentially rearward, and the reference of other relevant parts of the body is similar.

The pipeline wheel booster ventilation compressor is a pipe rotation machine that uses a rotating acceleration pipe or a rotary deceleration pipe to interact with a flowing gas to transfer energy to the gas to obtain pressure.

The main component of the pipeline wheel booster ventilation compressor is a rotor composed of a ducted air duct wheel and a transmission shaft. The machine does not have a static stator component such as a rectifying flow and a diffuser, and the machining gas is used to complete the gas pressurization independently by the rotor. The rotor processing gas is mainly completed by the duct pipe. The duct pipe is arranged around a cylindrical (cylindrical cylindrical, conical tubular) duct wheel, and the duct pipe on the duct wheel is approximately circular or curved (the arc is also a ring) Part of the), when the duct wheel rotates, the airflow enters the duct pipe from the air inlet of the duct pipe, and then absorbs energy in the duct pipe to increase the pressure.

The air duct wheel comprises three parts: a duct sleeve, a cylindrical duct wheel and a duct pipe. The duct wheel is connected with the duct sleeve, and the transmission shaft drives the duct wheel to rotate through the duct sleeve. The tube wheel disc may be disc shaped, may be cylindrical, and may be conical in shape. The duct pipe is fixed on the duct wheel, and the duct wheel drives the duct pipe to rotate.

The duct pipe consists of the side wall of the pipe, the air inlet of the pipe and the air outlet of the pipe. The air inlet of the duct pipe can be arranged on the side wall of the duct pipe, and can be arranged on the front end of the pipe. The air outlet of the duct pipe can be arranged on the side wall of the duct wind pipe, and can be arranged at the rear of the pipe. On the end.

The duct pipe of the invention comprises a duct tube duct, a duct tube reversing deceleration duct, a duct tube cooling duct, a duct tube diverting duct and a high energy circulating thrust duct.

The pipeline wheel booster ventilation compressor of the invention is a new technology developed on the basis of the circulation supercharged pipeline compressor. The basic structure and working principle are basically the same as those of the circulating supercharged pipeline compressor, and the functional use is basically the same, and the compression can be processed. Pure gas, and can process compressed solid gas mixed gas, gas solid mixture. (Refer to the circulating pressurized pipeline compressor, patent number ZL20091 0216953. 0 ) ₀

The pipe wheel pressure booster compressor duct pipe wind pipe is basically the same as the circulating pipe compressor pipe air duct wind pipe. The duct pipe is the pipe body; the pipe body here includes the simple pipe body and the combined pipe. Two kinds of body, the simple-shaped pipe body refers to a fully-sealed air pipe such as a square pipe, a circular pipe or a flat pipe which is formed once, or a half which is directly recessed by a curved or circular groove around the duct disk. An open pipe body, or a semi-open duct that is wound and fixed on a duct disk by a spiral plate or a curved plate. The combined pipe body refers to a pipe body having a shape of a butt-type square pipe shape, a circular pipe shape, a flat pipe shape or the like which is formed by a pair of arc-shaped groove-like plate-like bodies. First, use a spiral plate or a curved plate to wind and fix the snail on the air disk wheel Rotary or curved grooves, and then the top ends (radial ends) of these grooves are closed to form a full-sealed combined duct. Such ducts are called full-sealed combined spiral ducts, or fully enclosed. Combined curved duct. Such a combined duct is a fully enclosed duct. The fully sealed combined spiral duct and the fully sealed combined curved duct belong to the innovative technology of the present invention.

The ducted tube composed of the fully-sealed duct can directly process the compressed gas, and the ducted wheel composed of the semi-open duct must be shielded by the compressor casing to process the compressed gas (the radial end of the semi-open duct side wall is provided) Exception to the leak-proof barrier).

The air duct air duct may be a closed airway (a duct air duct composed of a full-sealed duct), or a semi-open type (a duct air duct composed of a semi-open duct), half open The duct may have no duct side walls at the bottom or top. The cross section of the duct may be of equal cross section, either contracted or expanded. Which form you use can be based on actual needs.

The duct pipe is divided into a half ring (arc) and a full ring. The annular duct is attached to the duct wheel disc along the annular path of the rotor. The air duct has an arc shape (the arc is a part of the ring) or an annular duct air passage, and the air duct air passage is provided with a duct air duct inlet and a duct air duct outlet.

The air duct of the ducted air duct formed by the semi-annular duct is also semi-annular, and the longitudinal length of the air duct of the semi-annular duct is small and the gas flow is short. The full annular duct is divided into a single annular duct, a double annular duct and a multi-annular duct. The ducted tubes formed by the single annular ducted duct, the double annular ducted duct and the multi-annular ducted duct are respectively called a single annular duct wheel, a double annular duct wheel and a multi-annular duct wheel. Single ring boosting effect is good. , , ' '

One duct pipe can be provided with only one duct wind pipe (called a single pipe duct pipe), or more than two duct pipe ducts (called a multi-tube duct wheel). It is possible to form a single-tube duct wheel with only one full-sealed duct or one semi-open duct, or a combined duct with a full-sealed and semi-open ducted duct to form a single duct. Air duct wheel. It is possible to use a single-sealed ducted duct or a single semi-open duct to form a multi-tube duct, or a full-sealed duct and a semi-open duct. The combined duct forms a multi-tube duct wheel.

The invention also uses three working principles to process the compressed gas, that is, the pressing force boosting working principle, the rotating force boosting working principle, and the centripetal decelerating working principle.

Working principle of press force boosting: The airflow reverse rotor turns into the air duct air duct, and in the air duct airway, the reverse rotor turns to flow, absorbing energy and increasing pressure. The structural characteristics of the air duct wheel are that the air duct reverse rotor is attached to the air duct roulette by the steering, and the air duct of the airflow reverse rotor is flowed.

Rotating force pressurization working principle: It means that the airflow turns to the flow along the rotor, and continuously absorbs the energy to increase the pressure. The structure of the duct pipe is that the air duct is entangled with the rotor and wound and fixed on the duct of the duct to form the steering of the rotor. Air duct airway.

The principle of decelerating and supercharging of the centripetal force means that the airflow in the duct is from the radial end of the outer circumference of the duct The center of the rotor flows, and the reaction force of the centrifugal force absorbs the energy to reduce the speed and increase the pressure (the supercharging pressure is double, both the pressure of the gas flow itself decelerating the kinetic energy and the pressure of the centrifugal force increasing).

The invention can also use the above three working principles to simultaneously process the gas, and can simultaneously use the two working principles of the rotating force and the centripetal deceleration and pressurization to process the gas, and can simultaneously use the working force of the punching force and the rotating force. The processing gas can simultaneously use the working principle of stamping force and centripetal deceleration and pressurization. The gas can be processed separately by using the working principle of stamping force or the working principle of rotating force alone, but it cannot be used separately. The centripetal deceleration pressurization works to process the gas. The centripetal deceleration supercharged working principle must be based on the punching force and the rotating force to process the high-speed airflow to be implemented. The high-speed airflow must first flow from the outer circle to the center of the circle, and then the centrifugal force reaction force can decelerate and pressurize. The use of centripetal deceleration and boosting operation has certain limitations. However, the centripetal deceleration boosting operation principle is particularly effective for decelerating the airflow. The utility model is designed to ensure the normal operation of the compressor, and to ensure that the gas that meets the certain flow rate requirements of a certain pressure can be processed, and the centrifugal deceleration supercharged working principle must be used to achieve the gas. In particular, the high-pressure high-speed airflow processed by the rotating force must be decelerated by the centripetal deceleration to give appropriate boost deceleration before it can be used for output.

The pipe wheel booster ventilator compressor rotor may be cylindrical, conical, disc shaped or the like. The entire flow path of the cylindrical rotor is of equal section shape, and the conical rotor flow path is divided into a bold shape from front to back and from front to back (from the air inlet end of the rotor to its outlet end). Both. Whether it is expanded or contracted, the duct air duct of the duct can be of equal cross-section, either contracted or expanded.

The pipe compressor composed of the semi-annular and single annular duct wheel of the present invention is suitable for general ventilation and ventilation. The pipe compressor composed of double-ring and multi-annular duct wheels is suitable for high-pressure UHV blast, gas turbine pressurization and chemical production and processing of high-pressure gaseous substances.

Single-annular, double-ring or multi-annular ducted air ducts allow the gas entering the air duct of the gas compressor to be processed by the rotor for two weeks or weeks or weeks to absorb energy and then discharged into the pipeline. The compressor, that is, driven by the same rotor and the same drive shaft, without any fixed diversion facilities in the middle, the gas entering the pipeline compressor can be directly rotated for one week, two weeks or weeks or weeks to be processed and absorbed. Energy, which greatly simplifies the structure of the body, saves material, and reduces weight. Due to the simple structure, less material consumption and small volume, the friction area is small and obvious, and the utility model can completely achieve high efficiency and energy saving.

As a high-pressure or extra-high pressure pipeline compressor, the gas flow into the rotor needs to be more than two weeks. It is necessary to use a double-ring or multi-annular duct wheel composed of double or multiple annular ducts. The longitudinal length of the air passage of the double-annular and multi-annular ducted tube is twice as long as the outer circumference of the rotor. Therefore, the gas flow is large and needs to rotate with the rotor for more than two weeks. The air duct roulette is composed of a side wall of the duct bobbin, an air inlet of the duct tube and an air outlet of the side wall of the duct wheel. The air inlet of the duct disc is arranged inside the cylindrical duct disc, and the duct roulette The side wall air outlet is arranged on the side wall of the air duct wheel in the air inlet of the duct, and the air outlet of the side wall of the air duct is radially directed from the inner side of the air inlet side of the duct to the air inlet side of the duct On the outer side of the wall, the air outlet of the side wall of the duct wheel communicates with the air inlet of the duct of the duct of the air duct of the air duct, and the wind is directly introduced into the air duct of the duct from the air inlet of the duct. The duct pipe is wound around the outside of the duct wheel, and the duct wheel rotates. By means of the centrifugal force, the gas in the air inlet of the duct coil is easily sucked into the duct of the duct.

The air outlet of the side wall of the duct wheel may be in the form of a whole circular ring structure, or may be in the form of several arc-shaped structures, and a row of air outlets of the side wall of the duct pipe may be arranged in the air inlet of a duct wheel, also Several rows of duct duct side wall air outlets can be provided.

In order to make the air duct wind pipe more powerfully pumping and processing the gas, the air duct of the air duct of the present invention is further provided with a windshield inner support windshield wall, and the inner side of the air duct roulette is supported by the wind wind wall. The axial rear edge of the air outlet of the air duct of the air duct of the duct disk inlet, the radial end edge of the windshield support inner wall of the air duct is connected with the side wall of the wind turbine wheel, and the wind turbine wheel supports the windshield wall diameter The front end is connected with the sleeve of the air duct wheel, and the inner side of the duct coil supports the windshield wall to support the side wall of the duct wheel to form the inner cavity of the duct coil, which constitutes the air inlet of the duct coil; the inner side of the duct coil supports the windshield wall Connected to the duct sleeve, which causes the duct and the duct duct to rotate together with the rotor drive shaft. By blocking the windshield wall by the inner side of the duct wheel, it is ensured that the gas entering the air inlet of the duct coil does not flow axially to the outside of the duct wheel.

In order to further enhance the air intake amount of the air inlet of the duct pipe, the present invention can also add a wind deflector for the air inlet of the air duct on the inner wind support wall of the duct wheel, and the air inlet of the duct coil The axial rear edge of the baffle is connected to the axial front side of the windshield inner support windshield, and the radial rear end of the air duct of the air duct is directed to the side air outlet of the duct wheel. Air duct roulette inlet air deflector The deflector directly enters the air duct inlet duct from the duct inlet air inlet. The structure and function of the air deflector of the air duct of the air duct are similar to those of the general centrifugal fan impeller. It can be a single-wall structure, and it can be a post-flow synchronous rear fan impeller blade type, which can be pumped for it. The absorbed gas increases the flow rate and increases the pressure and speed of the gas it introduces. The gas processed by the air deflector of the duct inlet air inlet is sent to the air duct of the duct tube to process, which can make the gas in the duct of the duct tube get more pressure.

The air duct flute air inlet, the air duct reel side air outlet, the inner side of the air duct reel supporting the wind shield, and the air duct fling air inlet air deflector are all innovative technologies of the present invention. (Refer to the circulating supercharged pipe compressor, patent number ZL200910216953. 0).

In order to further enhance the supercharging effect of the duct wheel, the present invention can also add a duct tube reversing deceleration duct on the duct wheel, and the duct tube reversing deceleration duct is steered by the front and rear counter duct wheels along the axial direction of the duct wheel. Fixed on the duct wheel, the duct tube reversing deceleration duct inlet is connected with the duct tube duct, duct tube wheel The reversing deceleration duct outlet is also connected to the duct tube duct.

The air duct reversing deceleration duct is the same as the duct tube duct structure. The duct reversing deceleration duct can be wound and fixed on the duct wheel in parallel with the duct tube duct, and the revolving deceleration duct of the fixed structure type ducted coil is juxtaposed. A separate section or sections of pipe body, such a duct wheel reversing deceleration duct outlet can also be connected to the duct pipe outlet duct.

The air duct reversing deceleration duct can also be wound and fixed in series with the duct tube duct, and the duct tube reversing deceleration duct connected in series with the duct tube is part of the duct tube duct, but only the duct tube wheel. The air duct flows in the opposite direction. It is turned by the reverse duct wheel. It can be one or several sections of the duct body connected to the duct pipe duct in series or sections.

The function of the ducted reversing deceleration duct is to decelerate the airflow and increase the pressure for the airflow. Since its airflow direction is opposite to that of the air duct, it can transmit energy to the gas by the reaction of the rotating force, so that the airflow reduces the flow velocity. , increase the pressure. The ducted air duct transmits kinetic energy for the gas. The ducted wheel reversing deceleration duct transmits the potential energy for the gas. The two ducts complement each other and cooperate with each other to obtain a sufficient supercharging effect.

During the working process of the duct pipe, the air pressure of the air duct of the duct pipe at the rear of the duct wheel is large, the temperature is high, the expansion is large, and the pipeline is easily blocked, so that the airflow cannot flow. To overcome this obstacle, the duct wheel is guaranteed. In normal operation, the present invention also provides a ducted tube cooling air duct on the duct wheel, and the duct tube cooling duct is steered and fixed on the duct wheel by the front and the rear duct tube wheel along the axial direction of the duct tube wheel, and the duct tube cools the wind.

The best way to implement the invention

Embodiment 1, referring to FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, a pipeline wheel booster ventilation compressor, comprising an organic shell 1, a casing air inlet 2, a casing air outlet 3, and a rotor 4 , Rotor drive shaft 5, duct pipe 6, cylindrical tubular duct wheel 7, duct tube wheel side wall 8, duct sleeve 9 and 6 full-sealed combined spiral duct tube duct 10 ( A spiral groove is formed by winding the front and rear winding spiral plates along the axial direction of the duct wheel, and then the radial end of such groove is covered with a circular annular plate to form a spiral duct), and the air duct side wall 11 is Refers to the spiral plate, or the sidewall 8 of the duct wheel, or the top cover of the spiral groove, which belongs to the side wall of the duct wind pipe 1 1 ), the duct air duct 12 of the duct (refers to the spiral groove) , air duct air duct air inlet 1 3 (also air duct wheel side air outlet 11), duct tube air duct air outlet 14, full-sealed combined spiral duct wind duct 10 0 along the duct tube axial direction From the front and the rear, the wind turbine wheel is wound and wound for two weeks and fixed on the air duct wheel, that is, the air duct tube 10 and its duct tube air duct have an absolute length of air. The circumference of the tube wheel is circumferentially connected to the rotor shaft 9 of the duct. ' ' mouth

The compressor duct pipe is actually 6 pipes. For the sake of brevity and clarity, it is convenient to explain the problem. Only one pipe is drawn in the drawings of the embodiment.

In this example, an axial flow fan (used by a motor to drive the drive shaft 5 to rotate) is used for general ventilation and ventilation, and is used for the suction and discharge of a gas solid mixture.

During operation, the motor shaft drives the rotor to rotate, which drives the duct wheel to rotate. The air duct wheel rotates, and the full-sealed combined spiral air duct sucks in gas from the air duct flue air inlet 15 through the side air duct wind duct air inlet 13 and the air duct wheel side air outlet 16 to suck in The gas enters the spiral duct air duct 12 and then spirally rotates with the rotation of the duct wheel. During the spiral rotating flow, the energy is continuously absorbed, the flow rate and pressure are increased, and then the axial spiral duct is passed. The air duct air outlet 14 of the side wall 11 of the wind duct forms an axial air flow, is then discharged to the air duct outlet duct 29, and is discharged to the air outlet 3 of the casing through the air duct outlet duct 29, and then After being discharged from the body, the airflow discharged from the body is still axial.

In this case, the airflow into the body is axial, and the airflow from the body is also axial. This example can be used as an axial flow fan. Since the inhaled airflow passes through the air passage of the rotating spiral duct, the rotating flow absorbs energy, and the rotating flow for two weeks absorbs more energy, so the outlet air pressure at the outlet is relatively high, the same ratio. The centrifugal high pressure blower of the power is even higher.

This example is suitable for use as a high-pressure axial flow blower. Used as a high-pressure axial blower, than traditional The multi-stage series axial flow blower is simple in structure, small in size, light in weight, and saves raw materials in processing and production. It is easy to handle, install, use and maintain, and has high efficiency and energy saving.

Embodiment 2, referring to FIG. 6, FIG. 7, and FIG. 8, this example is basically the same as Example 1, except that the air duct of the air duct of the air duct 15 is axially rearward. The inner side of the duct wheel is provided with a windshield support wall 17, and the inner side of the air duct of the air duct supports the radial end of the windshield wall 17 and is connected with the side wall 8 of the duct, and the radial front end is connected with the sleeve 9 of the duct. The inner side support windshield wall 17 of the duct coil is provided with 12 air duct wheel inlets and air guiding baffles 18 in the form of synchronous rear flow fan impeller blades, and the axial guiding rear edge of the air guiding deflector is followed by the air duct wheel The inner side of the disc supports the windshield wall 17 to be connected to the axial front side. The radial front end of the wind deflector is directed toward the duct sleeve, and the radial rear end is directed toward the duct air outlet side wall 16 of the duct.

The second difference is that, in this example, the axial front end side (spiral plate) of the spiral front end of the spiral ducted pipe is provided with the air inlet of the duct pipe, and the inlet direction thereof is forward. The air duct wheel is turned, that is, the air duct wheel of the present example is provided with two air ducts of the duct tube air inlet 1 3 , that is, the air duct tube air duct axial side wall duct tube air duct air inlet 1 3 , duct tube wheel Air duct radial side wall duct wind duct air inlet 1 3.

During operation, each ducted duct is made up of a ducted pipe, a radial side wall, a ducted air duct, an air inlet, and a wind tunnel, and the air duct is driven by a centrifugal force. The air inlet of the duct 1 3 enters the wind by the negative pressure formed by the rotating force; the double part double-intakes into the wind, and the air intake is large.

During operation, the gas entering the air inlet 15 of the duct coil is firstly pressurized by the air inlet baffle 18 of the air duct of the duct, and then sucked into the air duct 12 of the spiral duct air duct, and then rotated. Processing, twice processed, out of the airflow from the duct outlet of the duct, the wind speed will be higher.

In this example, a stamped air-inflating pipe head can be connected to the outside of the axial side air duct of the duct pipe duct, and the inlet of the stamping air-inflating pipe head is turned to the wind pipe. By using the rotary punching force to enter the wind, it is also possible to achieve a better air intake effect.

This example is suitable for the manufacture of high-flow high-pressure axial flow fans, which are used for ventilation, air supply, and suction and delivery of solid mixture materials.

Embodiment 3, referring to FIG. 9, FIG. 10, FIG. 11, FIG. 12, this example is basically the same as the example 2, except that the axial length of the duct wheel is large, and the wind turbine wheel is provided with a spiral wound for 20 weeks. The air duct wheel duct 10 and the spiral duct tube wound for 10 weeks are reversed to the deceleration duct 19, and the spiral duct duct reversing duct 19 is inserted between the spiral duct ducts 10 every two weeks. The absolute length of the ducted air duct 10 and the ducted wheel deceleration duct 19 is 30 times the circumference of the duct wheel.

The second difference is that the outer side of the radial edge of the duct wheel and the inner side of the side wall of the casing are provided with an annular duct wheel cooling air inlet duct 20, and the cooling air inlet duct is imported into the outer space of the straight air duct wheel, and the outlet is followed by the wind. The tube wheel cooling air duct exhaust pipe 25 is connected, and the cooling air inlet duct is further provided with a ring axial fan fan blade type cooling air inlet duct air guiding baffle 21, and the wind guiding vane radial front end air duct The radial end wall of the wheel is connected, not connected to the side wall of the casing, it will rotate together with the duct wheel, and the outside is cooled. The wind flows through the duct wheel to cool the intake duct. In this example, the axial end of the duct tube is provided with a spiral duct wheel cooling duct 22, and the spiral duct tube cooling duct structure is the same as the spiral duct tube duct, and its axial front end is provided with cooling stamping. The air inlet pipe 27, the cooling stamping air inlet pipe inlet is reversed to the wind pipe wheel steering, and the cold air is sucked from the air duct wheel cooling air inlet pipe 20 by the rotary punching action. The duct tube cooling duct outlet is connected to the duct tube cooling duct exhaust duct 25. A ring of ducted duct cooling ducts 22 is blended between the ducts of the air ducts at the rear of the axial direction of the duct.

During operation, the gas processed by the air deflector of the duct inlet air inlet, the gas entering the spiral duct wind pipe is firstly rotated by the air duct wind pipe for two weeks to accelerate, and then the flow is reversed into the spiral wind. The tube wheel reversing speed reducer rotates one revolution to reduce the deceleration pressure; then flows into the duct tube air duct and rotates for two weeks to increase the speed, then flows into the duct tube reversing deceleration duct to rotate one revolution to reduce the pressure, and then flows into the duct The wind tube rotates for two weeks to increase the speed of the processing, and then flows into the duct to reversing the deceleration duct for one rotation to reduce the pressure, until finally, the gas entering the duct tube will pass 10 times. After 20 weeks of processing and increasing speed, after 10 times of 10 weeks of processing, the supercharging is accelerated, and finally, the air duct of the duct wheel can discharge high-pressure gas with particularly high wind pressure.

Since the axial end of the duct wheel is provided with a spiral duct wheel cooling duct, the duct duct cooling duct is interposed between the duct duct ducts, and the duct wind cooling duct air duct cold wind can make the wind The high temperature gas in the air duct of the tube wind tube is fully cooled, and does not expand and block the air passage, which can ensure the smooth flow of the duct air duct.

In this example, due to the high rotor speed, the absolute length of the ducted air duct and the air duct reversing deceleration duct is large, and the processing flow is long. Therefore, the UW tube can be processed to meet the needs of the UHV airflow. This example is suitable for the production of high-pressure UHV gas compressors for processing compressed pure gases or solid gas mixtures.

Embodiment 4, referring to FIG. 13 , this example is basically the same as Example 3, except that the air duct wheel 6 is not provided with a duct tube cooling air duct, but 6 duct tube high energy circulating thrust ducts are provided. 28, high-energy circulating thrust duct 28釆 is composed of simple-shaped oblate tube, high-energy circulating thrust duct 28 inlet with duct tube axial rear high-pressure high-temperature spiral duct tube duct 10 countercurrent connection, its outlet with duct tube axle The forward spiral duct wind duct 10 is in a forward flow direction.

In this example, a fixed centripetal confluence unit 2 3 is provided at the axial rear portion of the compressor, and a rotary centrifugal reducer 24 is disposed in the fixed centripetal confluent unit 23. The rotary centrifugal reducer 24 is fixed to the rotor drive shaft 5 like a centrifugal fan impeller, and rotates with the rotor to decelerate and pressurize the centripetal flow of air flowing from the outer circle to the inner circle discharged from the duct wheel.

During operation, the high-energy circulating thrust air duct of the duct wheel leads the high-temperature, high-pressure and high-energy airflow from the axially rear spiral ducted air duct of the duct wheel, and is sent to the axially front spiral duct duct of the air duct wheel. The low-pressure and low-temperature airflow advances, so that the gas flow pressure in the air duct of the duct pipe is always high and then low, and there is never a backflow, no surge will occur, and the duct wheel can be kept normal. jobs.

During operation, the high pressure gas processed by the ducted air duct 10 and the ducted wheel to the decelerating duct 19 is discharged into a fixed centripet convector 23 at the rear of the axial direction of the compressor, and rotated by the rotary centrifugal reducer 24. The reaction force of the centrifugal force, that is, the deceleration and pressurization of the centripetal force, is then subjected to processing compression, and finally a suitable high-pressure UHV low-speed airflow can be obtained. In this case, the pressurization is double, that is, the air duct and the duct wheel are firstly processed by the deceleration duct, and then processed by the rotary centrifugal reducer.

In this example, since the duct pipe is wound around the duct wheel for 30 weeks, the duct wheel reversing deceleration duct is wound around the duct tube for 15 weeks. The absolute length of the duct air passage is larger, the processing flow is longer, and the pressurization is double. Therefore, this example can process extra-high pressure airflow to suit the needs of use. This example is suitable for use in high pressure ultra high pressure compressors.

Embodiment 5, referring to FIG. 14, FIG. 15, FIG. 16, FIG. 17, this example is basically the same as the example 4, except that the duct pipe 6 of this example is not provided with a high-energy circulating thrust duct of the duct wheel, and is not provided. The duct tube cooling air duct is provided with a sleeve type air duct wheel 31 on the radially outer side of the duct tube 6, and the sleeve type air duct wheel 31 is sleeved on the outer side of the duct tube 6, and the sleeve type duct wheel 31 It is provided with a sleeve type duct tube duct 10, and the sleeve type duct tube duct 10 is also a full-sealed combined spiral duct structure. The spiral sleeve type duct tube duct is along the sleeve type duct tube. The axial direction of the disk is steered and fixed on the sleeve type air duct wheel 31 by the rear and front sleeve type duct tube wheel, and the sleeve type air duct wheel vent 32 is provided on the side wall of the sleeve type air duct wheel. The sleeve type air duct roulette air duct air inlet 13 is connected with the air duct wheel air outlet 14 through the sleeve type air duct roulette port 32 (the duct tube air duct outlet 14 is arranged in the duct tube air duct) On the radial end side wall, the spiral sleeve type duct tube duct outlet 14 is disposed on the radial end side wall of the sleeve type duct tube duct.

In the axial rear part of the sleeve type duct tube (the axial front part of the duct tube), a spiral sleeve type duct tube splitter duct 26 is provided, and the sleeve type duct tube splitter duct 26 is along the sleeve type duct. The axial direction of the wheel is from front to back (the axial direction of the duct is from the front to the front). The sleeve type duct tube is steered and fixed on the sleeve type duct tube. The sleeve type duct tube is divided into the inlet and the sleeve type duct. The wheel duct 10 is connected, and the sleeve type duct tube split duct outlet is connected with the sleeve type duct tube duct outlet 14. The sleeve type ducted wheel splitter duct 26 is made of a one-time forming fully enclosed round tube.

In this example, the air outlet 3 of the casing is disposed on the radial side wall of the casing. Since the sleeve type air duct air outlet 14 is provided on the radially outer side wall and the outlet direction is rotationally tangential, this example is suitable for the radial side wall of the casing.

In the operation of this example, the gas sucked in by the air inlet 15 of the duct is firstly changed from the duct pipe of the duct pipe to the deceleration duct 19, and flows forward and backward, processing the supercharging, and then the duct is exhausted by the duct The tuyere 14 is input into the sleeve type duct tube duct 10, which flows from the front to the front, and pressurizes the machining once. In this case, the supercharging pressure is double, that is, the first air duct wheel rotation force is supercharged, and the second sleeve type duct tube wheel rotation force is increased, so the wind pressure of the compressor outlet duct of this example is high.

In this case, since the sleeve type air duct wheel is provided with a ducted pipe splitter duct 26 at the axial rear portion, the sleeve is set. The high temperature and high pressure airflow in the rear duct of the tubular duct wheel is shunted, which will not cause the pipeline to block and form surge, and the compressor can be kept working normally.

In this case, due to the sleeve type duct wheel, the axial size of the whole compressor will be shortened by nearly half, the volume is small, the material is used less, and the resources are saved. The supercharging pressure is double, the supercharging effect is high, the efficiency is high, and the energy is saved.

This example is adapted for use as a high pressure UHV compressor for compressing general gas and other solid gas mixtures, liquid solid gas mixtures, and gas liquid mixtures.

Embodiment 6, with reference to Figure 18, this example is basically the same as Example 3, except that in this example, there is no duct tube cooling air inlet duct 20, no cooling air inlet duct air deflecting vane 21, no air duct. The inner side of the wheel disc supports the windshield wall 17, but an axial flow fan impeller vane type air duct disc air inlet air deflector 18 is arranged in the air duct inlet 15 of the duct, and the air inlet port of the duct coil is axially inserted. The side wall of the rear duct wheel is provided with a side wall auxiliary air outlet 30 of the duct, and the side wall auxiliary air outlet 30 of the duct wheel is connected with the duct cooling duct 22.

During operation, the axial flow guide duct air inlet air deflector 18 will directly blow cold air to the axial rear portion of the air duct disc air inlet, and the cold air is assisted by the air duct wheel side wall. The tuyere 30 flows into the duct cooling duct 22, and absorbs the heat of the duct tube duct 10 and the duct wheel reversing deceleration duct 19 through the duct tube cooling duct side wall, so that the duct tube duct and The air duct reversing deceleration air duct can be cooled, so that the air duct air duct and the duct tube reversing deceleration air duct air passage can be prevented from being blocked and reversed, thereby avoiding surge, and thus the compression can be ensured to continue normal operation.

Same as the example 3, this example is suitable for the production of high-pressure UHV gas compressors. Industrial application, fet
