Abstract

The utility model relates to a coal mine underground gas drainage pipeline automatic outward accumulated water discharging technology, which belongs to a technology suitable to be used for outwards discharging accumulated water in various pipelines in a negative pressure state. A section of pipeline system is arranged in a drainage pipeline, the upper part is a pipeline in a hollow square shape, and the lower side is a section of vertical pipeline; the water outlet part is made into a U-shaped pipe; a one-way outward water discharging cover door is arranged above a water discharging opening; when a gas-water mixture in a drainage pipeline passes through a water discharging device, the gas-water separation is realized through the pipeline part in the hollow square shape positioned at the upper part; gas enters the upper part pipeline; water and a small amount of gas fall into the lower part pipeline; the gas returns to a main drainage pipeline through a bypass pipeline in the hollow square shape; the cover door is automatically opened and closed to realize the automatic water storage and water discharge through the integral effects of effective height difference of the accumulated water and the drainage negative pressure; and a manual gate valve is arranged at the bottom of the U-shaped pipe, so that particles such as deposited silt can be conveniently discharged out.

Description

A kind of gas drainage pipeline automatic bleeder
The technology that this technology of technical field relates to coal mine gas extraction pipeline outwards discharges ponding automatically, a technology of the automatic outwards discharge of applicable all kinds of negative pressure state lower pipelines ponding.
The existing negative pressure line of background technology is normally discharged ponding, adopts water storage device is installed on pipeline, at intake-outlet, one place's gate valve is respectively set, and timing manually opens and closes respectively gate valve and discharges water, and because releasing pipe discharge ponding is comparatively frequent, wastes very much man-hour; Also there is the tailrace that automechanism is set by connecting special inside at pipeline, need the compound actions such as distribution due to controlling organization, easily break down; Two kinds of modes all exist aspects such as being subject to air pressure to affect simultaneously, and in pipe, water can not effectively enter tailrace, all has the undesirable situation of the effect of discharging water.
Summary of the invention is for addressing the above problem, and we design one simple auxiliary piping system of laying structure on main line, reach the effectively stably effect of automatic-discharging ponding.
The technical scheme that the technical problem that the utility model solves is taked is: by one section of pipe-line system is installed in extraction pipeline, top is " return " type pipeline; Below is one section of vertical duct, makes " U " type pipe at water outlet, and top, dewatering outlet arranges a unidirectional lid door outwards discharging water; When in extraction pipeline, air-water mixture is by this jettison gear, the proportion difference of air water " is returned " type pipeline portions and is utilized on top, realize to greatest extent gas-water separation, gas enters upper pipeline, water and a small amount of gas fall into bottom pipeline, gas is got back to main extraction pipeline by " returning " type bypass pipe, water imports bottom water storage pipeline, water storage pipeline is the part that top caliber is larger, coupling part, bottom adopts the less pipeline of diameter, as long as the effective discrepancy in elevation of ponding is greater than negative pressure of suction, can realizes automatic water-storing and discharge water; Make dewatering outlet: " U " type pipe, the mouth of pipe arranges the unidirectional lid door of outwards discharging water, and the ponding outwards discharge automatically that reach a certain height, when being discharged to when a certain amount of, lid door automatic fall-back prevents that atmosphere is extracted in pipe, in " U " type pipe bottom, a hand sluice valve is set and is convenient to emit the particles such as silt sediment.
The effect that the utility model is useful is, be installed on extraction pipeline, extraction air-water mixture is after jettison gear, utilize gravity principle, heavier water and particle fall back to the pipeline that discharges water, by the pipeline automatic-discharging that discharges water, to outside object, simple in structure being easy to safeguarded, is difficult for breaking down or damaging.
Brief description of the drawings further illustrates the utility model below in conjunction with accompanying drawing.
Accompanying drawing is vertical section structure figure of the present utility model
1 is the extraction gas (arrow is for flowing to) of water entrainment; 2 for taking off the extraction gas (arrow is for flowing to) of water; 3 is " returning " type pipeline portions of device; 4 is water storage pipeline portions; 5 pipeline portions that connect for improving the discrepancy in elevation; 6 is dewatering outlet and Gai Men; 7 is " U " type pipeline portions; 8 is the gate valve of discharged particle.
Detailed description of the invention is mainly to utilize gravity principle, when the extraction gas flow of extraction pipeline water entrainment is in the time that this installs, separate at 3 " returning " type pipeline entrance, most of gas rises and enters main line, the descending bottom pipeline that falls into of water and small part gas, water imports bottom 4 water storage pipeline 5 connecting lines, gas is got back to main extraction pipeline by " returning " type bypass line, water is that effective discrepancy in elevation (the vertical discrepancy in elevation between pipeline liquid level and 6 delivery ports is stored up in bottom 4) is while being greater than negative pressure of suction when gathering a certain amount of, water flows out automatically, in the time being less than negative pressure of suction, lid door automatic fall-back under Action of Gravity Field is closed no longer and is discharged water, in the time of termination of pumping or maintenance, dewatering outlet " U " type pipeline effect is to preserve certain water column sealing interior or exterior space, prevents that the pernicious gases such as gas from leaking, bottom gate valve effect is in the time of the deposited particles thing of bottom, can manually open gate valve and emit.So far realize the repertoire of this device water discharging and particle.
