Embodiment

Present embodiment is an example with the level Four hydathode, and the concrete structure of level Four hydathode is described in detail.

See Fig. 1, Fig. 2, Fig. 3, Fig. 4, the level Four hydathode is used for before gas compressor or goes into the drainage means of as fired fuel feed channel, and total effectively water seal height equals 4 times of effective water seal heights of single-stage hydathode.

The level Four hydathode by a high pressure gas suction port 1, two 2, one flow-offs of low-pressure gas suction port 3, three connecting tube 4, one diffuse mouthfuls of 5, three relief openings 6, two hand holes 7, one go up that water inlet 8, four discharge water and sewage draining exit 9, top blind flange 10, base plate 11, two (one) 12, dividing plates (two) 13 of dividing plate, cylindrical shell 14, flow-off 3 on ball valve 15, one go up ball valve 16 on water inlet 8 pipelines, three fixedly critical piece such as the angle steel of bottom connecting tube and pipe collar 17 form.

See Fig. 2, top blind flange 10, base plate 11, two (one) 12, dividing plates (two) 13 of dividing plate are divided into four zones to whole hydathode cylindrical shell 14 by shown in Figure 1, connect by connecting tube 4 between per two zones, totally three connecting tube, each zone is exactly the one-level hydathode, altogether the level Four hydathode.

See figure, a high pressure gas suction port 1 is located at the top of first order hydathode, and the bottom puts in the first order hydathode, at the bottom of the inlet tube to liquid level be the one-level water seal height, will come tracheae to join with moisture-laden gas in the production, and take to be threaded, but also flange connects.

Two low-pressure gas suction ports 2 are located at each one of the both sides, top of level Four hydathode, if coal gas comes atmospheric pressure to be lower than one-level hydathode water seal height, can directly connect one of them low-pressure gas suction port in the production, and standby blank flange sealing is stand-by when no.

See Fig. 2, Fig. 3 and Fig. 4, establish one in the top middle portion of fourth stage hydathode and diffuse mouth 5, link to each other, discharge the coal gas in the hydathode as required with technology coal gas diffusion pipe.

See Fig. 2 and Fig. 3, a relief opening 6 respectively is installed at the top of the first order, the second level, third level hydathode, when need during moisturizing, are at first opened this three relief openings in hydathode, can moisturizing.

See Fig. 1, Fig. 2, a filling pipe end 8 is located at the top of fourth stage hydathode, and promptly the low voltage terminal of this hydathode is used for water filling first of this hydathode and the moisturizing of producing.

See Fig. 3, Fig. 1, a flow-off 3 is located at the upper lateral part of fourth stage hydathode cylindrical shell, and a ball valve 15 is established in outlet, and the ordinary production ball valve is often opened, and when having only moisturizing aborning, it is shut, and when treating that the water yield reaches overflow situation in the cylindrical shell, opens this ball valve.

See Fig. 3, center, cylindrical shell 14 both sides, level Four hydathode bottom is arranged with two hand holes 7, promptly leans on the bottom in the both sides of first order hydathode and fourth stage hydathode cylindrical shell, is used for the bulk dirt in the hand cleaning hydathode.

See Fig. 2 and Fig. 3, respectively establish one at the side lower part of the cylindrical shell of the first order, the second level, the third level, fourth stage hydathode and discharge water and sewage draining exit 9, discharge water when being used in the periodic cleaning hydathode ponding, dirt and stopping using hydathode.

See Fig. 1 and Fig. 3, for preventing three connecting tube 4 play, it is fastening with angle steel and pipe collar 17.

Four zones of hydathode cylindrical shell and three connecting tube 4, in the hydathode cylindrical shell with each semicylinder about centrosymmetric two the complete parallel and isometric dividing plates 12 of cylindrical shell are divided into draining inside, form the first order, fourth stage hydathode, centre at these two dividing plates 12, and a perpendicular other dividing plate 13 is divided into the second level to remaining hydathode cylindrical shell, third level hydathode, connect by a connecting tube 4 between every two-stage hydathode, totally three connecting tube, each connecting tube manages the end to liquid level and is the one-level water seal height, three connecting tube so, be exactly three grades of water seal heights, add the one-level water seal height of high pressure gas inlet tube, be total to the level Four water seal height, be exactly total the water seal height of this level Four hydathode.

The working procedure of this device: the level Four hydathode is installed under the gas compressor inlet preceding pipeline usually, through rust cleaning, leak tests etc. after the assay was approved, at first open the ball valve 15 on the flow-off 3, open the ball valve 16 on water inlet 8 pipelines again, to the internal water flooding of level Four hydathode, there is the water overflow to represent that promptly water has reached normal water level position shown in Figure 3 in the hydathode up to seeing at flow-off 3, at this moment can come into operation, come feed channel and high pressure gas import 1 to join, high pressure gas import 1 puts in the first order hydathode, the pipe end and connecting tube 4 are contour, if gas pressure surpasses the one-level water seal height, then the water in high pressure gas import 1 pipe will be pressed into second level hydathode in interior connecting tube 4, can see that flow-off 3 has water to overflow, in like manner if gas pressure is higher than twice one-level water seal height, then the water in the pipe will be pressed into third level hydathode in interior connecting tube 4 in the connecting tube in the hydathode of the second level 4, at this moment can see that flow-off has water to overflow, if gas pressure is higher than three times of one-level water seal heights, then the water in the connecting tube in the third level hydathode 4 pipe will be pressed into fourth stage hydathode in interior connecting tube 4, can see that flow-off has water to overflow.So the highest water seal height of this hydathode can not surpass four times of one-level water seal heights.
