Embodiment Construction
[0021] The present technology will be further described through the embodiments below in conjunction with the accompanying drawings.
[0022] In the embodiment, the condensed water in the external gas pipeline enters the I chamber through the inlet flange 12, settles in the I chamber, and then the settled condensed water enters the II chamber. When the water level rises to a certain position, the water makes the floating ball 6 float, With the support 2 as the center of the circle, the lever 5 swings upward in an arc, thereby driving the sliding guide rod 7 and the sealing guide rod 8 to lift, and opening the valve port 17 to realize drainage. When the water level drops to a certain position, the water makes the floating ball 6 drop, and through the lever 5 with the support 2 as the center of the circle, it swings downward in an arc, thereby driving the sliding guide rod 7 and the sealing guide rod 8 to lift, closing the valve port 17, and realizing reliable closing .

The invention relates to a float rod type coal gas drainer. Aiming at the situation that coal gas condensed water contains a large amount of impurities, firstly the impurities of the condensed water are effectively separated through a mode of gravity settling, and then the condensed water enters in a water draining process. Based on buoyancy of a floating ball and a level principle, a water draining port is opened and closed through transmission of the lever force depending on change of the water level and lifting of the floating ball, and thus water draining is achieved. The coal gas draineris different from a working principle of a water seal drainer currently used. When the coal gas pressure fluctuates within a certain range, changing of the position of the floating ball cannot be caused, opening and closing actions do not occur, and thus the problem that the water seal drainer is punctured due to fluctuation of the coal gas pressure is solved. A water draining mechanism of the float rod type coal gas drainer has the characteristics that one end of a lever is treated as a fixed supporting point of the lever, the other end serves as the floating end of the floating ball, the middle supporting point is a movable point and consistent with the movement direction of the floating end, the floating end is the generating end of power, and the middle supporting point is a power output point.
Description
technical field [0001] The invention relates to the technical field of gas condensed water discharge equipment, and the technology is used for a gas drainer for discharging condensed water in gas pipelines. Background technique [0002] At present, the gas condensate discharge equipment mainly uses water-sealed gas drains. Water-sealed drains are generally only suitable for low and medium pressure gas pipelines below 50kPa. If they exceed 50kPa, their volume will be quite large. When the gas pressure reaches 50kPa--300kPa, the water seal drain can hardly solve the gas condensate discharge problem. [0003] For example, after blast furnace dedusting and purification before TRT power generation, the gas pressure is in the range of 200-300kPa. In addition, the gas pipeline after the gas pressurizer also has the problem of how to discharge the accumulated water in the pipeline, and the gas pressure often exceeds 50kPa. [0004] In addition, the method of using electric water le...
