Description
Technical field
The present invention relates to a kind of vertical foam-making apparatus of annular supply, it is adaptable to the dust such as underground coal mine getting working face
Point depositing dust operation.
Background technology
With the continuous improvement of underground coal mine mechanization production degree, various operation intensities are continued to increase, traditional mine
Dust prevention and control means can not have been met in modern production the need for dust prevention and control；Long-term work is in high concentrate dust environment
Workman also deeply hurts, and the pneumoconiosis problem of coal industry is the most serious.Accordingly, the development of mine dust Prevention Technique and leather
It is new also extremely urgent.
Foam dust suppression technology make use of that foam specific surface area is big, spreadability is good, adhesiveness is strong, wettability is strong, water consumption is small
The features such as, underground coal mine driving face it is dust-proof in served very significant effect.The angle occurred from foam is come
See, the foaming capacity of the foam generation Processes and apparatus of existing underground coal mine driving face application is relatively low, in small water, low hair
It is difficult to produce high expansion foam under conditions of infusion addition, gas release deficiency can not realize effective bag of the foam to dust region
Wrap up in, so as to influence the dust-laying effect of foam.In summary, research and develop one kind and adopt driving face suitable for underground coal mine, in little Shui
The foam-making apparatus that high expansion foam can be produced under conditions of amount, low foaming agent addition is significant.
The wider foam occurring mode of application mainly has the foaming of net formula to be foamed two kinds with disturbed flow type at present.Net formula foaming mechanism
Predominantly：Foaming agent and the mixed expanding foam solution of water are equably sprayed on foam screen, effect foaming is advertised using distinguished and admirable；
Disturbed flow type foaming mechanism is mainly：Using perturbation mechanism, expanding foam solution produces violent turbulent vortex movement in pipeline with distinguished and admirable,
And then produce foam.
Wherein, in Application No. 201010297133.1 and 96114291X patents, net formula foam pattern is make use of, is steeped
Foam multiple is higher；It is disadvantageous in that foam outlet pressure is low, foam jet contains motion apart from short in foam-generating device
Part and electric component, on the one hand reduce the stability and reliability of device, on the other hand add underground coal mine it is high-risk,
Application difficulty in small space；In the patent of Application No. 2010102904036, disturbed flow type foaming effectively solves foam
The problem of outlet pressure is low, meets transport and the injection needs of foam, but such foam device foaming capacity is poor, it is impossible to
Realized under conditions of small water low foaming agent addition compared with high-foaming multiple.
Fluid is foamed during flowing in the horizontal direction in above-mentioned foam-making apparatus, by gravity shadow
Ring, liquid is easily collected on device bottom, cause foam that air produces with expanding foam solution can not be in foaming cylinder and foam screen
On be uniformly distributed, therefore there is the shortcomings of foaming capacity is relatively low, be unsatisfactory for the requirement of underground coal mine face foam dust suppression.
The content of the invention
Goal of the invention：Vertical bubble is supplied it is an object of the present invention to provide a kind of annular suitable for underground coal mine getting working face
Foam generating means, overcomes in existing coal mine downhole foam dust control technology and has that foam maker foaming capacity is poor, conventional foam
Generator foam outlet pressure is low, small injection dynamics and the problem of foam skewness.
To achieve these goals, present invention employs following technical scheme：A kind of vertical foam of annular supply occurs
Device, including feed flow joint, air connector, foaming cylinder, foam screen, foam transport pipeline, atomizer and base, base are set
Feed flow joint and air connector are equipped with, base upper end is connected with foaming cylinder lower end, and atomization is set in foaming cylinder lower inside
Nozzle, atomizer is connected by liquid feeding pipeline with feed flow joint, and foam screen is set in foaming cylinder inside upper part, and foam cylinder
Upper end is connected with foam transport pipeline.
Further, it is described foaming cylinder be upright cylindrical shape, foaming cylinder highly for foam barrel diameter 1.5~
2 times, foaming cylinder is connected with foam pipeline road and base respectively by flange.
Further, the foam screen is fitted by stainless steel cloth with cotton net forms, and the mesh number of foam screen is 4~10
Mesh.
Further, the atomizer is located at foaming cylinder axis line position, the atomization angle of atomizer for 90 °~
120 °, the distance of atomizer and foam screen is 0.3~0.5 times of drum diameter.
Further, the base includes lateral wall and the small diameter cylinder that is arranged on inside lateral wall, lateral wall and small
Constituted between diameter cylinder and inlet and air inlet offered on the annular gas distribution cavity of closing, lateral wall, inlet with it is small
Diameter cylinder interior is connected, and air inlet is connected with annular gas distribution cavity, and two air distribution ports, two are offered in small diameter cylinder
Air distribution port is symmetricly set in air inlet axis both sides, and feed flow joint is arranged on inlet, and air connector is arranged on air inlet.
Beneficial effect：The present invention does not use moving component and electric component, improves the stability and peace of traditional foam maker
Quan Xing；Foaming cylinder employs upright type of design, it is to avoid the influence of the skewness for the foam that gravity is caused；Using atomizer
Expanding foam solution is uniformly sprayed on foam screen, the contact area of increase expanding foam solution and air-flow is conducive to foam to produce；Understructure
The supply mode of foam device gas can be simplified, while ensure that air evenly into foaming cylinder, it is to avoid by supplying
Gas is uneven to produce foam skewness, the low problem of expanding foam solution utilization rate；The foam screen that cotton net is combined with stainless (steel) wire can
Effectively to stick expanding foam solution, in double materials laminating design of foam screen, stainless steel cloth firm for a long time can maintain mesh stable,
Cotton net can play retention adhesive attraction to expanding foam solution, and double-deck material laminating design improves the reliability of foam screen and durable
Property, the vertical depositing dust foam maker of present invention annular supply disclosure satisfy that the generation high magnification numbe under the conditions of low foaming agent addition
Foam needs.
