Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of natural gas compression equipment, in particular to compression equipment of a long-distance natural gas compression station. Background Art
[0002] In a typical compressor station process, multiple compressor units are usually used to provide boosting, and the power of these compressor units is generally provided by gas turbines. However, with the increase in the volatility of pipeline load demand, the pipeline network is in a low-load operation state for a long time, resulting in low-operating conditions of gas turbines, resulting in low energy utilization efficiency and reduced economy. In order to solve this problem, the concept of hybrid vehicles can be used to optimize the current compressor station configuration. One feasible method is to increase energy storage equipment or introduce technologies such as clutches to improve the economy of the operation of the compressor units in the entire station. First, by adding energy storage equipment, the excess energy generated by the compressor unit at low load can be stored. These energy storage devices can be in the form of batteries, supercapacitors, etc., to store excess energy and release it when the pipeline load demand increases, thereby reducing the load of the gas turbine. Secondly, the introduction of technologies such as clutches can achieve flexible control of the compressor unit. Through the control of the clutch, the compressor unit can be flexibly selected to be turned on or off according to the real-time pipeline load demand to achieve the best energy utilization efficiency. When the pipeline load demand is small, some compressor units can be shut down to keep the gas turbine in an efficient operating state; when the pipeline load demand increases, the energy storage device can be started to release energy and more compressor units can be turned on to meet the pipeline demand while maintaining the efficient operation of the gas turbine. The implementation of the above measures can effectively improve the overall economic operation of the compressor station, reduce energy waste, reduce operating costs, and improve equipment utilization and reliability.

In the initial state, the conical push block 218 is not in contact with the pressing wheel 223. As the temperature inside the compression housing 201 rises, under the action of the expansion thrust piece, the sliding ring 219 will drive the conical push block 218 to contact the pressing wheel 223, thereby triggering the spray operation. As the temperature increases, the pushing amplitude of the expansion thrust piece increases, the pushing amplitude of the conical push block 218 on the pressing wheel 223 increases, the spray volume increases, and the heat dissipation effect is better.

At this time, the DC motor 102 is used as a driving force to drive the gas compression component 200 to work. On the contrary, under the action of the switching drive member, the clutch transmission disc 113 at the output end of the gas turbine 101 is in contact with the transmission gear 115, and the power of the DC motor 102 is cut off, so that the gas turbine 101 provides power for the gas compression component 200.

In the initial state, the conical push block 218 is not in contact with the pressure wheel 223. As the temperature inside the compression shell 201 rises, under the action of the expansion thrust piece, the sliding ring 219 will drive the conical push block 218 to contact the pressure wheel 223, thereby triggering the spray operation.

The evaporation of the water mist will further absorb heat, thereby improving the heat dissipation effect. As the temperature increases, the pushing amplitude of the expansion thrust piece increases, the pushing amplitude of the conical push block 218 on the pressure wheel 223 increases, the spray volume increases, and the heat dissipation effect is better.
