Abstract
The utility model proposes a kind of atomizer for suppressing dust with dry mist, including sprayer body, inlet channel, admission line, mixing chamber, hole for water spraying and fumarole are provided with the sprayer body, the two ends of the mixing chamber are connected with the inlet channel and hole for water spraying respectively, and the admission line is connected with the fumarole and connected by through hole with the mixing chamber.The utility model clever structure, is atomized twice to liquid, i.e. effervescent atomization and pneumatic nebulization so that the fogdrop diameter after atomization is smaller than 2.5 μm, and with the higher speed of service, effectively increases anti-dust effect.
Description
Technical field
The utility model belongs to technical field of environment protection equipment, and in particular to a kind of atomizer for suppressing dust with dry mist.
Background technology
In industrial and mining enterprises, the improvement to dust is always a great problem.Counted according to the Ministry of Public Health, China's pneumoconiosis turns into duty
Industry disease is the first, accounts for the 80% of total occupational disease.Dust in air, granular size is different, distribution is different.The master that dust suppression is administered
The respirable dust particle for wanting the dust granules that object is less than 150 μm, especially particle diameter to be less than 10 μm.Although it is total in material
Proportion is less than 1% in weight, but its long-term suspension is in air, it is difficult to settle, and can even float hundred kilometers of row sometimes, to people
The harm of body is especially big, is to cause pneumoconiosis and the main contributor of atmosphere pollution, seriously threatens the health and lives of the mankind.
Suppressing dust with dry mist technology, is that water smoke is melted into ultra-fine droplet, and when dust-contained airflow bypasses droplet, grit is due to inertia meeting
From the air-flow streamed deviate and with droplet bump against be captured, i.e., by the inertial collision of powder dust particle and drop, intercept and
The effects such as cohesion, diffusion, which are realized, to be caught so that the particle diameter of grit becomes big, settles down under gravity, reaches gumming
The purpose of grit.If droplet particle diameter is much larger than dust granules, then dust only follows the gas around water fog particle
Stream motion, water fog particle is contacted seldom with dust granules or is not in contact with all, and does not reach dust suppression effect.Therefore, droplet
The whether sufficiently small effect for determining suppressing dust with dry mist of diameter.
Utility model content
The purpose of this utility model is to propose a kind of atomizer for suppressing dust with dry mist, and the atomizer can spray diameter
Droplet less than 2.5 μm.
What the technical solution of the utility model was realized in：A kind of atomizer for suppressing dust with dry mist, including shower nozzle
Inlet channel, admission line, mixing chamber, hole for water spraying and fumarole, the two ends point of the mixing chamber are provided with body, the sprayer body
It is not connected with the inlet channel and hole for water spraying, the admission line is connected with the fumarole and mixed by through hole with described
Room is connected.
Operation principle of the present utility model is：Pressure in admission line is more than the pressure of inlet channel and the pressure of mixing chamber
Compression stroke in power, admission line mixes with water into mixing chamber and forms bubble, bubble accelerates during two-phase flow,
Liquid, is squeezed into thread and is sprayed water in leaving in the extremely short distance in aperture, due to inside and outside differential pressure by deformation, expansion in water spray aperture
Increase and drastically expand in addition explode, brin line is fried into trickleer droplet；From fumarole spray high velocity air with
Very high relative velocity is formed between droplet, very big frictional force is produced, air-flow produces strong tear to droplet and made with shearing
With droplet is so as to by secondary-atomizing, form the smaller droplet of diameter, while accelerating the speed of service of droplet.
More preferably, in order to reach preferably atomizing effect and spray velocity, a diameter of 1~2mm of the hole for water spraying is described
A diameter of 1~3mm of fumarole.
More preferably, the angle between the jet axially bored line and the water spray axially bored line is 5~20 °, to obtain preferably mist
Change effect, while obtaining faster spray velocity.
More preferably, the quantity of the fumarole is 2~6, and ring is uniform.
The utility model clever structure, is atomized twice to liquid, i.e. effervescent atomization and pneumatic nebulization so that after atomization
Fogdrop diameter be smaller than 2.5 μm, and with the higher speed of service, effectively increase anti-dust effect.

Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Provided with water inlet in the atomizer for suppressing dust with dry mist as depicted in figs. 1 and 2, including sprayer body 1, sprayer body 1
Pipeline 2, four admission lines 3, mixing chamber 5, hole for water spraying 7 and four fumaroles 6, the two ends of mixing chamber 5 respectively with inlet channel 2
Be connected with hole for water spraying 7, admission line 3 is connected with fumarole 6 and connected by through hole 4 with mixing chamber 5, hole for water spraying 7 it is a diameter of
1.2mm, a diameter of 1.8mm of fumarole 6, the angle theta between the axis of fumarole 6 and the axis of hole for water spraying 7 are 9 °.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
