Environment-friendly treatment equipment for flowback fluid of coal-bed gas well

Abstract

The invention discloses coal-bed gas well flow-back fluid environment-friendly treatment equipment, and relates to the technical field of flow-back fluid treatment, the coal-bed gas well flow-back fluid environment-friendly treatment equipment comprises two bases preset on the ground; the two sand collecting pools are respectively fixed on the upper end surfaces of the two bases; the sand discharging bin is fixed between the two sand collecting pools, a liquid inlet is formed in the position, close to the top, of one side of the sand discharging bin, a liquid outlet is formed in the position, close to the bottom, of the other side of the sand discharging bin, and valves are installed on the liquid inlet and the liquid outlet correspondingly; the fixed shaft is fixed between the two sand collecting pools and penetrates through the sand discharging bin and the sand collecting pools, and a synchronous wheel is rotationally arranged at the end, located in one of the sand collecting pools, of the fixed shaft; the rotating motor is fixed outside one of the sand collecting pools and is connected with the synchronous wheel through a synchronous belt; and the sand discharging assembly is coaxially arranged on the fixing shaft, is located in the sand discharging bin and is fixed to the synchronous wheel through a plurality of connecting columns which are circumferentially arranged.

Description

technical field [0001] The invention relates to the technical field of flowback liquid treatment, in particular to an environmental protection treatment equipment for the flowback liquid of a coalbed methane well. Background technique [0002] The CBM well flowback fluid is the liquid produced during the fracturing and mining of the coal seam. When the flowback fluid is discharged, it will carry a large amount of sediment. Only then can it be discharged or continued to be used. [0003] The existing flowback liquid treatment equipment firstly transports the flowback liquid into the collection tank, and then removes the sediment and other large particles carried by it through gravity sedimentation. When the flowback liquid is injected into the next process, the flow of the liquid will carry part of the sediment that settles, so that the next process needs to be removed again, which greatly affects the work efficiency. [0004] In view of the above problems, the present inve...

AI Technical Summary

Problems solved by technology

[0003] The existing flowback liquid treatment equipment must first transport the flowback liquid to the collection tank, and then remove the large solid particles such as sediment carried by it through gravity settlement. The process requires a long waiting time, and when the settlement in the collection tank is completed When the flowback liquid is injected into the next process, the flow of the liquid will carry part of the settled sediment, so the next process needs to be removed again, which greatly affects the work efficiency
