A continuous automatic water discharge and slag discharge device for gas drainage pipeline

Abstract

The invention belongs to the field of gas extraction and relates to a gas extraction pipeline continuous and automatic drainage and deslagging device. The gas extraction pipeline continuous and automatic drainage and deslagging device is composed of a main device tank, a water tank, a gas extraction inlet, a gas negative-pressure extraction port, a condensing system, a pressure regulating system, a control system, a drainage and deslagging system, a water level monitoring system, a water and slag mixer, a pressure monitoring system, a separating plate guide groove and a separating plate, wherein the water tank is arranged inside the main device tank and separated into an upper tank body and a lower tank body by the separating plate; the condensing system can condense steam inside gas and collecting water into the water tank; the water level monitoring system and the pressure monitoring system are connected with a control system so that the control system can control opening and closing of the separating plate as well as pressure regulation of the pressure regulating system; water and slag can be uniformly mixed by the water and slag mixer and then drained via the drainage and deslagging system. The gas extraction pipeline continuous and automatic drainage and deslagging device is stable in system operation, high in interference resistance, convenient to arrange, full in automation and capable of saving manual operation and achieving continuous and efficiency operation.

Description

technical field [0001] The invention belongs to the field of gas drainage, and relates to a continuous automatic water discharge and slag discharge device for a gas drainage pipeline. Background technique [0002] In the process of coal mining, due to the large amount of gas in the coal seam, in order to mine safely and greenly, it is necessary to extract the gas from the coal seam and collect it for reuse. During the gas extraction process, under the action of negative pressure, the water and cinder contained in the coal seam enter the gas extraction pipeline, and the water and cinder gradually accumulate in the gas extraction pipeline to block the drainage pipeline, making it difficult for gas to enter in time The main drainage pipe affects gas drainage and brings hidden dangers to coal mine safety production, so it is necessary to discharge water and slag in time. [0003] The gas drainage water discharge and slag discharge device is a device that collects cinders and wa...

Problems solved by technology

[0004] The technical problems in the prior art solved by the present invention are waste of manpower and material resources, untimely discharge, clogging of the drainage device and the drainage pipe, and the interaction between the gas negative pressure drainage and the water discharge and slag discharge process in the gas drainage process, and the synchronous pumping cannot be performed. Due to intermittent and discontinuous mining process, automatic cleaning of equipment and devices, etc., it is hoped that an electrical device can be used to realize the automation of water discharge and slag discharge, without manual intervention, to reduce production costs, and to achieve one-time discharge of water slag to prevent slag from being trapped inside the extraction device. Accumulation leads to clogging of the drainage system, so as to realize safe and efficient gas drainage
