Description
Technical field
The utility model relates to the direct dragging system of steam turbine, particularly can replace the direct dragging system of motor-driven steam turbine.
Background technique
At present, most of large-sized power plants (water pump, blower fan, air compressor etc.) of China's industrial field are all run with motor run, need to consume a large amount of high-quality electric energy, add power load and power cost, and due to high capacity motor inrush current large, when input and switchover operation, can impact electrical network, be unfavorable for the safe operation of using electricity system.The Load Regulation of equipment needs to be realized by frequency variator, and cause operation to run complicated, produce harmonic wave, rate of fault is high.
On the other hand, many industrial enterprises need could utilize after high temperature and high pressure steam pressure and temperature reducing that is self-produced or that buy, cause steam kinetic energy and hot loss of energy.
In high temperature and high pressure steam pressure and temperature reducing utilizes, indicate in document " temperature-decreased pressure reducer regulates and applies in high pressure and medium pressure steam " and apply temperature-decreased pressure reducer how better with by high pressure steam Methyclothiazide use, but obviously cause the kinetic energy of high-quality steam and hot loss of energy.
In the utilizing of steam turbine, patent " equipment that a kind of low temperature heat of lime kiln is recycled " and " a kind of device utilizing plant gas preparing natural gas " etc., object is all utilize steam turbine to carry out drive unit with energy saving, but reckon without from steam turbine discharge low pressure steam still can be used for industrial production.
In steam energy cascade utilization, document " technical innovation of steam energy cascade utilization " is described a practical application, utilizes back pressure type steam turbine generator to reach the object of steam energy cascade utilization.But due to vapor pressure, temperature reason, the efficiency being applied to the steam turbine generator in this transformation is not high, and can not break away from the use to temperature-decreased pressure reducer after transformation, therefore perfect not to the cascade utilization of steam energy.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming prior art, a kind of energy loss reducing steam converter valve throttling process to greatest extent and cause is provided, realizes steam energy cascade utilization and the steam turbine of saving power directly drags the new equipment of power equipment.
Steam turbine of the present utility model directly drags the new equipment of power equipment, it comprises turbine engine, the nozzle of described turbine engine is connected with high pressure steam transfer line, described high pressure steam transfer line is provided with flow control valve and pressure regulator valve, the low-pressure steam outlet of described turbine engine is connected with sub-cylinder by low pressure steam transfer line, the rotary output of the gear-box of described turbine engine is connected with power equipment by coupling, and the control unit of described turbine engine is connected with the aperture of control valve with pressure regulator valve with flow control valve.
The beneficial effects of the utility model are: adopt steam turbine to replace motor Direct driver power plant, throttling and the cooling effect of reducing-and-cooling plant is substituted by steam turbine acting, the cascade utilization of steam energy can be realized, greatly reduce the power consumption of enterprise, the rotating speed of power plant can also be regulated in real time according to the change of load, easy-to-operat, increases operational reliability; By directly dragging large-sized power plant with steam turbine, can the overbottom pressure complementary energy of high temperature and high pressure steam be changed into mechanical energy, under the prerequisite not affecting steam operation parameter, substitute motoring power equipment, reduce the energy loss that steam converter valve throttling process causes to greatest extent, realize the cascade utilization of steam energy, and saving power and the free adjusting realizing power equipment.
Accompanying drawing explanation
Accompanying drawing is the schematic diagram that steam turbine of the present utility model directly drags the new equipment of power equipment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Steam turbine of the present utility model as shown in drawings directly drags the new equipment of power equipment, it comprises turbine engine, the nozzle of described turbine engine is connected with high pressure steam transfer line, described high pressure steam transfer line is provided with flow control valve and pressure regulator valve, the low-pressure steam outlet of described turbine engine is connected with sub-cylinder by low pressure steam transfer line, and the rotary output of the gear-box of described turbine engine is connected with power equipment by coupling.The control unit PLC of described turbine engine is connected with the aperture of control valve with flow control valve with pressure regulator valve, and the parameters such as the rotating speed adjusting turbine rotor and the vapor pressure that enters production technology, to meet production technology demand.
The steam (3.43MPa) of elevated pressures causes turbine nozzle from entry end, in nozzle, convert pressure energy to kinetic energy, after steam leaves nozzle, impacts turbine rotor blade, and to turbine acting, turbine rotor exports rotating mechanical energy.The high rotating speed of turbine rotor to suitable running speed through the gearbox speed reduction of turbine engine, then drags power equipment by coupling and rotates.
The steam (1.37MPa) flowing through the lower pressure after turbine enters gas-distributing cylinder, provides the steam meeting parameter request to enterprise.
