Description
Technical Field
The utility model belongs to defeated field of coal bed gas pipe way collection, concretely relates to defeated pipeline hydrops of coal bed gas collection prevents stifled device.
Background
The coal bed gas mining adopts a drainage gas production process, the coal bed gas gathering and transportation generally adopts a multi-well series connection technology, in order to reduce the cost, the coal bed gas generally adopts moisture gathering and transportation, and because well site process equipment is simple, a simple gas-liquid separator is additionally arranged, only a small part of coal bed gas saturated water which is mined from a well head can be separated, condensed water is easily formed in the long-distance gathering and transportation process, and under the condition of low external temperature, accumulated liquid sediment is easily caused to block a pipeline no matter at a straight position or a bent position of the pipeline and the pipeline is easily blocked due to freezing, so that the gathering and transportation efficiency of the whole gathering and transportation pipeline is influenced, and huge loss is caused to enterprises.
Disclosure of Invention
The utility model discloses to the defeated in-process of current coal bed gas pipeline collection, under the effect of factors such as topography, temperature, cause the hydrops in the defeated pipeline of collection not to flow, finally lead to the defeated pipeline of collection to block up, influence the problem of defeated efficiency of coal bed gas collection, provide a coal bed gas defeated pipeline hydrops and prevent stifled device.
The utility model adopts the following technical scheme:
the utility model provides a coal bed gas defeated pipeline hydrops prevents stifled device, which comprises an outer shell, the both ends of shell are equipped with the opening of being connected with coal bed gas defeated pipeline respectively, be equipped with drive impeller I of being connected through pivot and shell lateral wall respectively in the shell, gear I, drive gear II, drive impeller II and gear II, drive impeller I and I coaxial coupling of gear, drive impeller II and II coaxial coupling of gear, gear I, drive gear II and gear II mesh in proper order, one side of the opening part that shell and coal bed gas defeated pipeline's gas input end are connected is equipped with the oblique guide plate, the free end of guide plate is close to the tip of drive impeller I.
The centers of the gear I, the transmission gear II and the gear II are located on the same horizontal line.
The driving impeller I is close to one side of the shell, and the driving impeller II is close to the other side of the shell.
The diameter ratio of the driving impeller I to the driving impeller II is 3: 1.
The cross section of the guide plate is S-shaped.
The utility model has the advantages as follows:
after the gas in the coal bed gas gathering and transporting pipeline passes through the guide plate, gas pressure pushes the driving impeller I to rotate clockwise, the driving impeller I on the back of the driving impeller I rotates in the same direction, and after the driving impeller I and the driving gear II on the middle portion pass through, the driving impeller II drives the gear II to rotate anticlockwise, so that the driving impeller II can generate thrust on accumulated liquid, the accumulated liquid flows along the pipeline and the gas in the same direction, the problem that particulate matters in the accumulated liquid are deposited for a long time to block, and the accumulated liquid does not flow to freeze the gathering and transporting efficiency which is caused to be.
The utility model discloses do not rely on external force, only utilize the defeated pressure of collection of coal bed gas in the pipeline to promote the rotation of drive impeller II, mix the hydrops in the defeated pipeline of collection, to its produce with the thrust of air current syntropy, can be according to the determining deviation on the defeated pipeline of collection, install in the corner to effectively prevent the defeated pipeline jam problem of collection that the hydrops does not flow and cause. The utility model discloses low in manufacturing cost, the simple installation can effectively solve the interior long-pending liquid of pipeline and influence coal bed gas pipe transmission efficiency scheduling problem.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in the figure, a coal bed gas defeated pipeline hydrops prevents stifled device, which comprises an outer shell 1, the both ends of shell 1 are equipped with the opening of being connected with coal bed gas defeated pipeline respectively, be equipped with drive impeller I3 through pivot 2 and shell 1 lateral wall connection respectively in shell 1, gear I4, drive gear I5, drive gear II 6, drive impeller II 7 and gear II 8, drive impeller I3 and gear I4 coaxial coupling, drive impeller II 7 and gear II 8 coaxial coupling, gear I4, drive gear I5, drive gear II 6 and gear II 8 mesh in proper order, shell 1 is equipped with oblique guide plate 9 with one side of the opening part that coal bed gas defeated pipeline's gas input end is connected, the free end of guide plate 9 is close to the tip of drive impeller I3.
The centers of the gear I4, the transmission gear I5, the transmission gear II 6 and the gear II 8 are located on the same horizontal line.
