Abstract

A foam dust removal system used for coal mine underground is mainly composed of a quantitative adding pump, a foaming agent storage tank, a compressed air pipeline, a clear water pipeline, a foam maker, a foam spray nozzle, and other components. By utilizing the prior water pipe in a dust removal place, a foaming agent is added into the water pipe through the small-flow quantitative adding pump; a mixed liquid containing the foaming agent and compressed air pass through the foam maker, so as to generate a large amount of foam; the foam is delivered to the foam spray nozzle via a hose, and sprayed in an umbrella shape by the foam spray nozzle, thereby covering a dust producing point. The foam dust removal system is particularly suitable for a coal mine underground excavation working face, a conveyer belt transferring point, a tunnel excavation cross section or other dust producing points with narrow spaces, and effectively controls dust producing sources. Furthermore, the foam dust removal system has the advantages of simple structure, convenient operation, continuous working capability, high dust removal efficiency, no electrical element, safety and reliability.

Description

A kind of foam dedusting system that is used under the coal mine
Technical field
The utility model relates to a kind of foam dedusting system that is used under the coal mine, is particularly useful for the improvement of narrow and small place, space dust disasters such as down-hole mining work plane.
Background technology
In progress of coal mining, can produce a large amount of dust, and digging operation is the master operation of producing dirt, its dust-producing amount accounts for more than 80% of total dust, the physical and mental health of serious harm coal miner.Present about 260,000 people of pneumoconiosis patient of China's coal-mine industry, and with annual 5000 people's speed increase, annual nearly 3000 people die from pneumoconiosis, have brought great misery for patient and family thereof.In order to prevent and treat dust, generally adopt measures such as spray for dust suppression and coal-bed flooding under the coal mine, but the dust disaster of all failing because efficiency of dust collection is low well to prevent and treat.Abroad just begin to concentrate as far back as the seventies in last century and studied foam dust-removing, but dust collection method mainly is foam maker to be installed in produce near the dirt pits, relies on a large amount of foams with distinguished and admirable motion covering dirt source, as the Makeni of the former Soviet Union.The shortcoming of this method has two aspects, be that a large amount of foams appear at the workplace on the one hand, influence workman's operation, the foam maker volume can not be installed near the pick of coal-winning machine and fully-mechanized digging machine too greatly flexibly on the other hand, so can not effectively control the main product dirt root of the digging operation under the coal mine.Because above two aspects and other, foam dust-removing technology is not used widely under the coal mine yet at home.The patent No. is that CN87106798A discloses a kind of rock drilling bubble dust collector, it mainly is made of foaming premixed liquid holding vessel, compressed air line and froth nozzle, though this device is better dust removal effect when the rock drilling bore operation, but it can not realize continuous operation, and volume is also bigger, and the inner foam screen of froth nozzle adopts plane structure, be unfavorable for the expanding foam solution film forming, foaming effect is bad, is not suitable for the dedusting of working continuously of getting working face, and range of application is little.
The utility model content
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and volume is little, and dependable performance can continuous operation, better dust removal effect be used for foam dedusting system under the coal mine.
The utility model is used for the foam dedusting system under the coal mine, comprise the blowing agent fluid reservoir, foam maker and foam nozzle, described foam maker links to each other with water inlet pipe with compressed air hose respectively by pipeline, the pipeline that links to each other with compressed air hose is provided with control valve, and is provided with control valve, strainer and flap valve successively on the mouth of pipe that water inlet pipe links to each other; Respectively and be provided with quantitative interpolation pump between compressed air hose that links to each other with foam maker and the water inlet pipe, the air inlet pipe of quantitatively adding pump links to each other with compressed air hose by pipeline, and its pipeline is provided with the control valve of control flow; The drain pipe that quantitatively adds pump links to each other with the feed tube of foam maker, and its pipeline is provided with the control valve and the flap valve of control flow; Quantitatively add pump and link to each other with the blowing agent fluid reservoir by feed tube, drain pipe links to each other with water inlet pipe; The outlet of foam maker connects a foam dispenser by sebific duct.
Described foam maker comprises the housing that is combined as a whole by cylindrical shell and cone, be provided with the foam screen that combines by cone and arc surface in the housing, the bottom of housing is provided with the feed tube that links to each other with water inlet pipe, its sidewall is provided with the air inlet that links to each other with compressed air hose, and the water conservancy diversion spiral nozzle is housed on the feed tube; Having several diameters on the described foam screen is 2~3mm aperture; Described foam dispenser is provided with a plurality of foam nozzles.
The utility model is used for the foam dedusting system under the coal mine, is applicable to the improvement of narrow and small place, space dust disasters such as down-hole mining work plane, or efficiently administers the improvement of the dust disaster of getting working face and travelling belt transfer point under the coal mine.Native system utilizes a part of current in existing air line in down-hole and the inlet pipeline, the additive that adds proper proportion by quantitative interpolation pump in the current, foam by foam maker again, transfer to the place to use through pipeline, large stretch of foam is cut into small pieces, become the umbrella ejection by foam nozzle, cover and produce dirt pits, the foam of ejection evenly disperses, and can not cause foam to pile up, and does not influence workman's operation.System links to each other with the down-hole water pipe, and blowing agent adds immediately, and liquid is added in the preparation of need not stopping over, and can realize working continuously.Expanding foam solution film forming efficiency height in the foam maker, foam nozzle can be directly installed near the pick of coal-winning machine or fully-mechanized digging machine cutting-cylinder, directly covers and produces dirt pits, and through field trial, efficiency of dust collection can reach more than 95%.Native system is flexible for installation, only some foam nozzles need be installed in the place of work plane small space, and volume is little, and is flexible, do not need special additionaling power, simple to operate, uses reliably, has practicality widely.
