Abstract
The utility model discloses an anti-breakdown coal gas drainer which comprises an outer pipe, an inner pipe and supporting blocks, wherein the inner pipe is arranged in the outer pipe, a guiding pipe is arranged in the inner pipe, a plurality of supporting blocks are arranged between the outer pipe and the inner pipe, the bottom of one end of each supporting block is provided with beveled edges, the long edge is welded on the inner wall of the outer pipe, the short edge is welded on the circumcircle of the inner pipe, and the height of the other end of each supporting block is equal to that of the inner pipe and the guiding pipe; and the upper end of the guiding pipe is welded with a piston plate, and a pull rod is arranged at the center of the piston plate and penetrates through a center hole of a cover plate welded at the upper end of the outer pipe. The anti-breakdown coal gas drainer has simple structure, is convenient to install and operate, has good safety performance, utilizes water for sealing, and achieves the purpose of no leakage of cola gas.
Description
Technical field: the utility model relates to the coal gas industry, particularly relates to a kind of anti-breakdown coal gas drainer.
Background technique: in China's industrial trade, can use a large amount of coal gas and act as a fuel.And transport these coal gas; often all be to transport by a large amount of pipelines; particularly in China present stage; today of energy-saving and emission-reduction; the CO gas that a large amount of steel mills discharge is all adopting the variety of way method to reclaim, to reach the purpose of recycling and protection environment; but in the process that reclaims tail gas, the Safety performance of pipeline is a hidden danger always.If because the CO air pressure of carrying is too high, perhaps occur owing to foreign material and water blocking pipeline in the pipeline, the accident that will meet accident causes casualties.So when carrying the CO that blast furnace produced, on pipeline, all be provided with a drainage device at present every certain distance.But this drainage device, partial impurities and the water that generally also can only discharge in the coal gas to be contained, and for the excess pressure of coal gas, the pipeline breaking that causes but fundamentally is not controlled effectively and solves.
Summary of the invention: the purpose of this utility model is exactly that a kind of anti-breakdown coal gas drainer will be provided, and it can solve the existing problem of above facility effectively.The purpose of this utility model is achieved in that anti-breakdown coal gas drainer, is made up of outer tube, interior pipe, support block, it is characterized in that: be provided with interior pipe in outer tube, be provided with guide pipe in the interior pipe; Be provided with several support blocks between described outer tube and the interior pipe; Described support block one bottom portion is arranged to hypotenuse, and long side weld is connected on the inwall of outer tube, and in minor face is welded on the cylindrical of pipe, the other end and interior pipe, guide pipe are contour; Described guide pipe upper end and piston plate welding, the central authorities of piston plate are provided with pull bar, and pull bar passes from the cover plate central hole of outer tube upper end welding.The utility model is simple in structure, and fitting operation is convenient, and Safety performance is good, utilizes water to seal, and reaches the purpose that coal gas does not leak.
Description of drawings: Fig. 1 is the utility model structural representation;
1. outer tube, 2. support block, 3. in pipe, 4. piston plate, 5 pull bars, 6 cover plates, 7. guide pipe.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
Anti-breakdown coal gas drainer is made up of outer tube 1, interior pipe 3, support block 2, it is characterized in that: pipe 3 in being provided with in outer tube 1 is provided with guide pipe 7 in the interior pipe 3; Be provided with several support blocks 2 between described outer tube 1 and the interior pipe 3; Described support block 2 one bottom portions are arranged to hypotenuse, and long side weld is connected on the inwall of outer tube 1, and in minor face is welded on the cylindrical of pipe 3, the other end and interior pipe 3, guide pipe 7 are contour; Described guide pipe 7 upper ends and piston plate 4 welding, the central authorities of piston plate 4 are provided with pull bar 5, and pull bar 5 passes from cover plate 6 central holes of outer tube 1 upper end welding.During concrete enforcement, anti-breakdown coal gas drainer is arranged in the pipeline of coal gas blowdown, has an end setting of pull bar to make progress, after installing, inwardly inject the water of packed-piston from the circular hole of pull bar turnover.Support block is supporting the weight of piston plate and inner chamber injection water, and piston plate is tightly pushed down support block under the pressure of water, to prevent the leakage of coal gas.And when the coal gas in the gas pipe line surpasses certain pressure, perhaps carry the pipeline obstruction of coal gas, when build-up of pressure raises, this moment, coal gas will and be arranged on space between the guide pipe in the inner chamber extrusion piston plate that makes progress along the inner chamber of interior pipe, when greater than the weight of set water, piston plate will be by coal gas jack-up, this moment, piston plate was upwards withstood under the cover plate of outer tube under the effect of coal gas, the coal gas of being overflowed is close in pipeline by envelope again, and will be played the effect of warning by the piston rod of jack-up.During practical operation, the red ball of reporting to the police can be set at the top of push rod, or adopt and touch the warning device warning.So that the pipe fitter in time finds dangerous situation, get rid of hidden danger.After fault was got rid of, the pressure of coal gas will be got back to safe condition, and piston plate is return under the effect of guide pipe.The water that is overflowed just need add to certain height, thereby reaches the purpose that prevents gas leakage.
