Description
Technical field
The present invention relates to the drawing-off gas technical field, particularly a kind of method and the device thereof that need not shut down the gas pipeline slagging-off of slagging-off.
Background technology
The mining face under mine gas pipeline, because the drainage pump negative pressure is large, long-time use often causes problems such as " pipeline blockage, pump drainage are not smooth ", need the in time interior foreign material of cleaning pipeline, but because the mixed and disorderly substances in pipe confusion is difficult for focusing on, needs termination of pumping to tear gas pipeline open in addition when processing foreign material and remove the gred, cause the repair time long, both affected working surface production, again waste of manpower, material resources, repair time length also can cause face gas to transfinite, and has very large potential safety hazard for highly gassy mine.
Existing pipeline deslagging device, the gas drainage system of must stopping transport during slagging-off very easily causes gas exceeding limit, makes mine gas administer become unusual difficult.Can not concentrate the cleaning foreign material, slagging-off speed is slow, waste of manpower, material resources.Existing slagging-off pipeline is all installed in pumping plant, and limited location system can not effectively remove the gred.Can not monitor what of foreign material, artificial bad judging whether cleared up.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, cost is low, and method and the device thereof of the gas pipeline slagging-off of slagging-off can not be shut down in convenient monitoring.
For the deficiencies in the prior art, the invention provides a kind of method of gas pipeline slagging-off, at gas pipeline a threeway slag-discharging device is installed, be provided with a filter screen in the outlet side of threeway slag-discharging device, the slag-drip opening of described threeway slag-discharging device seals with blind plate, a gap bridge pipeline is connected in parallel on the gas pipeline, and described gap bridge pipeline is connected to the two ends of described threeway slag-discharging device, and inlet end and the outlet side of threeway slag-discharging device is respectively equipped with valve on described gap bridge pipeline and on the gas pipeline.Described gas pipeline upper filter screen installation place is provided with pressure sensor.During deslagging, first with the valve open on the described gap bridge pipeline, inlet end and outlet side with threeway slag-discharging device on the gas pipeline is respectively equipped with valve closing again, blind plate on the slag-drip opening of the threeway slag-discharging device on the gas pipeline is opened, operation just can remove the gred, simultaneously do not stop the gas exhaust place system, the original state of complete recovery that removes the gred gets final product.
For the deficiencies in the prior art, the device that the invention provides a kind of gas pipeline slagging-off comprises a threeway slag-discharging device that is installed on the gas pipeline, be provided with a filter screen in the outlet side of threeway slag-discharging device, the slag-drip opening of described threeway slag-discharging device seals with blind plate, comprise that also one is connected in parallel on the gap bridge pipeline on the gas pipeline, described gap bridge pipeline is connected to the two ends of described threeway slag-discharging device, and inlet end and the outlet side of threeway slag-discharging device is respectively equipped with valve on described gap bridge pipeline and on the gas pipeline.Described gas pipeline upper filter screen installation place is provided with pressure sensor.
During use, when gas pipeline is installed, this practical new gas pipeline deslagging device is installed at any part of gas pipeline as required, after installing with the valve closing on the top gap bridge pipeline of gas pipeline deslagging device of the present invention, with two valve opens on the gas pipeline, can open the gas exhaust place system, system is after operation a period of time, during foreign material process gas pipeline deslagging device place, can be stopped by filter screen, automatically stack is before filter screen, when the foreign material stacking volume surpasses pipeline after half, gas flow rate in the pipeline can increase, the pressure that produces also can increase relatively, at this moment can see intuitively the variation of pressure by the pressure sensor that is contained in the filter screen place, and then can distinguish whether the accumulation of gas pipeline foreign material is serious.
During slagging-off, first with the valve open on the gap bridge pipeline on this practical new gas pipeline deslagging device top, then two valves on the closed gas pipeline, at this moment methane gas just passes through from the gap bridge pipeline on top, gas pipeline just can carry out slagging-off work when not stopping the gas exhaust place system, blind plate on the slag-drip opening of the threeway slag-discharging device on the gas pipeline is opened, after foreign material are cleaned out, recovered original state and get final product.
Gas pipeline deslagging device of the present invention; simple in structure; cost is low; slagging-off can not be shut down in convenient monitoring, also can be according to the mine characteristics by cinder, stone and other large foreign material in the obstruction of stagewise screen baffle and the precipitation pipeline; purifying gas flow; the security of operation of protection gas drainage under suction equipment has been saved the man power and material, has improved the safety of highly gassy mine underground construction.
