Abstract
The utility model proposes a kind of dry fog case, including casing, the casing is provided with air inlet and gas outlet, the top of the casing is provided with some atomizers, the atomizer includes 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 is less than 2.5 μm of droplet in whole dry fog case full of diameter, is effectively increased dust removing effects.
Description
Technical field
The utility model belongs to technical field of environment protection equipment, and in particular to a kind of dry fog case.
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 that 2.5 μm of droplet can be less than in dry fog case, the dry fog case full of diameter.
What the technical solution of the utility model was realized in：A kind of dry fog case, including casing, the casing are provided with air inlet
And gas outlet, the top of the casing is provided with some atomizers, the atomizer include being provided with sprayer body, the sprayer body into
Waterpipe, admission line, mixing chamber, hole for water spraying and fumarole, the two ends of the mixing chamber respectively with the inlet channel and spray
Water hole is connected, and the admission line is connected with the fumarole and connected by through hole with the mixing chamber.
Operation principle of the present utility model is：Pressure in atomizer admission line is more than the pressure of inlet channel and mixed
The compression stroke closed in the pressure of room, admission line mixes with water into mixing chamber and forms bubble, and bubble is in two-phase flow mistake
Accelerate in journey, deform, expand, liquid is squeezed into water spray aperture thread and sprayed water in leaving in the extremely short distance in aperture, by
Drastically expand or even explode in the increase of inside and outside differential pressure, brin line is fried into trickleer droplet；Sprayed from fumarole
Very high relative velocity is formed between high velocity air and droplet, very big frictional force is produced, air-flow produces strong tear to droplet
Split and shear action, 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.
More preferably, dividing plate, the bottom phase of the dividing plate and the casing are provided with close to described gas outlet one end in the casing
Every.The structure causes dust directly will not be overflowed from gas outlet.
More preferably, the bottom of the casing is provided with blow-off pipe, and the blow-off pipe is provided with gate valve.
The utility model clever structure, is atomized twice to liquid, i.e. effervescent atomization and pneumatic nebulization so that whole dry
Droplet in fog chamber full of diameter less than 2.5 μm, effectively increases dust removing effects.
