The invention has lower demand on the steam pressure, as only 10-60kg, and it can burn the low-quality coal as 2000-4000 calorie; and it can improve the safety factor of high-pressure boiler. The invention can be matched with high-pressure impulse ejector; compared with constant-current compression steam turbine, it can improve 25-50% power efficiency.
Description
Technical field:
The present invention relates to a kind of mechanical steam turbine, the particularly a kind of and matching used energy-gathering pulse type steam turbine of high voltage plus injector.
Background technique:
The rotation of steam turbine blade at present is that high temperature, the high pressure steam that relies on high-pressure autoclave to produce sprays the blade rotation work done of pushing turbine from a plurality of jetburners with the constant current form.Want to improve the output power of steam turbine, just must improve the steam producing amount of high-pressure autoclave, improve the temperature and the pressure of steam, have following drawback for high-pressure autoclave: 1. power consumption is big, and the fat coal that must burn just can provide enough heat energy; 2. pressure is high more. and the selection to material is strict more, and technical requirements and the cost of making high-pressure autoclave are also high more; 3. high-pressure autoclave is uninterrupted use, burner hearth interior conduit rapid wear, maintenance difficulty; 4. the pipeline of high temperature and high pressure steam conveying is longer, and also there are some difficulties in the maintenance of pipeline.For this reason, I once developed the high voltage plus injector that a kind of vapor pressure only needs the special steam turbine of 10-60kg, safe and reliable, energy-conserving and environment-protective, can burn low-grade coal or low grade coal, (number of patent application: 200510120607.4), but but this sprayer can not be used for a steam turbine, can only be applicable to the energy-gathering pulse type steam turbine of my development.
Summary of the invention:
The objective of the invention is at above-mentioned deficiency, and provide that a kind of vapor pressure is lower, safe and reliable, the energy-gathering pulse type steam turbine of energy-conserving and environment-protective, can burn low-grade coal or low grade coal.
Energy-gathering pulse type steam turbine, by casing, stator, rotor main shaft, rotor blade, waste gas reclaims mouth, vapor injection port, the support pin is formed, it is characterized in that columned casing periphery has stiffening rib noise reduction layer, stiffening rib noise reduction layer is welded by the iron plate or the cast member of vertical and horizontal, the centre is filled with the swelling perlite powder sound absorbing material, stator is arranged in the casing, rotor main shaft, the stator periphery has the recoil baffle plate that distributes symmetrically, the earial drainage baffle plate, the casing two ends are connected with the stator head, seal groove and seal ring are arranged in the stator head, and rotor main shaft is hollow shaft in stator, there is bearing block support at two ends, defend tenaciously one group of T shape rotor blade 7 that distributes symmetrically on the hollow spindle, it is skewed that blade is, and becomes 10-25 degree angle with the main shaft tangent line, the blade face is curved, and radian is the 3-15 degree.4-8 vapor injection port, a 4-8 waste gas recovery mouth, one group of stator, group rotor blade are formed a cover autonomous system, and many cover systems can be connected on main shaft, and quantity is the 1-4 cover.One group rotor blade is consistent with the quantity of stator baffle plate, is the 8-24 sheet, distributes symmetrically.
During the supporting use of the present invention and high voltage plus injector, vapor pressure requires lower, the low-grade coal or the low grade coal of incendivity 2000-4000 kilocalorie, technical requirements to high-pressure autoclave can reduce, the corresponding safety coefficient that improves high-pressure autoclave also plays a positive role aspect energy-saving and environmental protection.

Accompanying drawing 2 is wherein a slice structural representation of energy-gathering pulse type steam turbine rotor blade;
Accompanying drawing 3 is an energy-gathering pulse type steam turbine longitudinal cross-section structural representation.
Embodiment:
The specific embodiment of the present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing 1 is an energy-gathering pulse type steam turbine lateral cross section structural representation.Energy-gathering pulse type steam turbine is made up of casing 1, stator 4, rotor main shaft 8, rotor blade 7, waste gas recovery mouth 9, vapor injection port 10, support pin 11, it is characterized in that columned casing 1 periphery has stiffening rib noise reduction layer 12, stiffening rib noise reduction layer twines whole casing by the iron plate of vertical and horizontal or cast member and is welded, mainly be the impact resistance that strengthens casing, simultaneously can be between the vertical and horizontal iron plate swelling perlite powder of high temperature resistant, heat insulation, the sound-absorbing of filling.Stator 4 is arranged in the casing, and the stator periphery has the recoil baffle plate 2 of two symmetries, is installed in waste gas and reclaims between mouth 9 and the vapor injection port 10, can intercept exhaust gas recirculation, springs back over the pulsed steam that sprays season to add high thrust on the rotor blade.The stator periphery also has ten earial drainage baffle plates 3 that distribute symmetrically, and the height of earial drainage baffle plate is a little less than the recoil baffle plate, and the impact force of pulsed steam to stator can be reduced in its space with partial pulse formula steam earial drainage to preceding a slice rotor blade.The recoil baffle plate reclaims mouth with waste gas, the vapor injection port number is consistent.
Accompanying drawing 2 is wherein a slice structural representation of energy-gathering pulse type steam turbine rotor blade; Defend tenaciously one group of T shape rotor blade 7 that distributes symmetrically on the hollow spindle, the blade lean shape becomes 15 degree angles with the hollow spindle tangent line, and the blade face is curved, and radian is 10 degree.Each group rotor blade is consistent with the quantity of stator baffle plate, for distributing symmetrically, can decide according to the steam turbine output power, can select between the 8-24 sheet.
Fig. 3 is an energy-gathering pulse type steam turbine longitudinal cross-section structural representation.Four vapor injection port 10, four waste gas reclaim mouthful 9, one groups of stators 4, group rotor blades 7 and form a cover autonomous system, and two cover systems are connected on the main shaft.The quantity of system can be decided according to the steam turbine output power, can select between the 1-4 cover.The stator two ends have stator head 6 to be connected with casing, and seal groove and seal ring 5 are arranged in every suit stator two ends, can prevent that pulsed steam is along rotor main shaft 8 earial drainages.Rotor main shaft is hollow shaft in stator, there is bearing block support at two ends.
The present invention must with the supporting use of high voltage plus injector (separate case application), pulsed steam has cumulative action, instantaneous burst power is bigger, the synchronous injection pulse formula of a plurality of jetburners steam promotes rotor blade and rotor main shaft rotation work done.Under the prerequisite of equal boiler, energy-gathering pulse type steam turbine is compared with constant current extruding type steam turbine, can improve about effect 25-50%.
