Abstract
A pressure reduction energy recovery system for a pneumatic motor differs from a currently-used throttling pressure reduction type or positive-displacementpressure reduction system and is a system capable of recovering energy released when the pressure of high-pressure gas is reduced to operation pressure. The pressure reduction energy recovery system with the structural type is simple in structure. An electric control system can open or close a solenoid valve to control flow of compressed gas and pressure of operation gas in a pressure stabilizing tank according to needs of the pneumatic motor. Timely adjustment can be carried out along with gradual reduction of continuous output pressure of the compressed gas so that pressure reduction energy can be recovered almost in the whole process, energy output and mechanical efficiency of the system are improved, and stable inlet pressure of the pneumatic motor can be ensured simultaneously. Therefore, the pressure reduction energy recovery system solves the problem of energy loss in pressure reduction of the high-pressure gas, is favorable for popularization and application, and has wide market prospects.
Description
Technical field
The present invention relates to a kind of decompression energy-recuperation system that is used for pneumatic motor, it is different from the expenditure and pressure formula or the positive displacement depressurized system of present use, is a kind of energy system that is discharged can reclaim high pressure air reducing to working pressure the time.
Background technique
Because the problem of energy density; The gas storage pressure of current pneumatic motor is all bigger; Usually about 15.0-30.0, and the pressure of real work gas is no more than 1.0MPa even lower usually, so we are beneficial to its work with regard to the pressure that needs depressurized system to reduce gas.Be applied at present on the pneumatic motor the most widely that depressurized system is the expenditure and pressure system, the positive displacement depressurized system then is the new depressurized system that just proposes recently.Two kinds of systems all are applied to pneumatic motor, make the interior gas output of gas tank and reduce its pressure, make it to reach the lower pressure that can work.Along with the work of pneumatic motor, gas will continue output, new high pressure air reducing arranged to low pressure again simultaneously, pour surge tank, form a dynamic circulation.Through monitoring to gas pressure in the surge tank, i.e. the working condition of may command depressurized system, and then can adjust the pressure of surge tank, make it to maintain all the time working pressure.
Throttle type decompression and positive displacement depressurized system all can reach lowering and stabilizing blood pressure makes it to be convenient to export the purpose that is easy to control.
But these two kinds of depressurized systems but all have a very large common shortcoming---the energy total loss when pressurized gas extremely can be worked low pressure by high pressure drop.High-pressure gas pressure decline can be accompanied by the increase of volume and the release of significant amount of energy, and pressure difference is big more, and then energy loss is many more.With 30.0MPa is example, if gas is reduced to 1.0MPa by 30.0MPa, the energy that loses because of decompression will occupy about 60% of total energy, if consider the output under the real work situation, then the energy because of the decompression loss will be more than 3 times of energy of actual output.Therefore lot of energy has been all owing to the reduction of pressure has wasted, and this also is the basic reason that pressurized air has that high energy density has only but that very low energy exports.
In sum, current depressurized system at stable operation pressure, is kept pneumatic motor normal operation output energy and is had important effect, is the necessary technology of pneumatic motor.But the shortcoming of current depressurized system also is obvious, and needs are a kind of for this reason can be with energy recovery and the new depressurized system that is used.
