A highly stable shale gas desanding device with a gravel storage mechanism

Abstract

The invention discloses a highly stable shale gas desanding device with a gravel storage mechanism, which includes a shale gas desanding assembly, a driving assembly, a diversion assembly and a flow diversion assembly, and is characterized in that: the shale gas The sand removal component includes an outer gas-solid separation tank, the outer gas-solid separation tank is sleeved with an inner gas-solid separation tank, and the inner gas-solid separation tank is connected with the shale gas mixture introduction pipe of the diversion component, and the shale gas The top of the sand removal module communicates with the outer gas-solid separation tank through the first pressure balance pipe, and the outer gas-solid separation tank communicates with the shale gas mixture introduction pipe through the second pressure balance pipe, and the second pressure balance pipe is equipped with pressure regulation Assemblies, the inside of the inner gas-solid separation tank is also equipped with a lifting and rotating diversion component, the input end of the diversion component is connected to the output end of the drive component; the invention can avoid the phenomenon of dust accumulation or blockage of the gas-solid separation device, Enhance the stability of the airflow vortex and improve the efficiency of gas-solid separation.

Description

technical field [0001] The invention relates to the technical field of shale gas desanding, in particular to a highly stable shale gas desanding device with a gravel storage mechanism. Background technique [0002] In the process of shale gas sand removal in related technologies, gas-solid separation devices are generally required. At present, there are still some shortcomings in the use of gas-solid separation devices for shale gas sand removal in the past. : [0003] In the process of gas-solid separation using the airflow vortex, the state of the airflow vortex is always in a fixed state, which will easily cause dust to adhere to the wall of the separation device, causing serious dust accumulation in the separation device and even causing blockage; Insufficient gas flow pressure often occurs at the inlet end of the shale gas mixture, which will lead to instability of the gas flow vortex and decrease the subsequent gas-solid separation efficiency.
