Abstract
The invention discloses a dry fog box which comprises a box body; the box body is equipped with a gas inlet and a gas outlet; a plurality of atomizing spray heads are arranged on the top of the box body; each atomizing spray head comprises a spray head body; a water inlet pipeline, a gas inlet pipeline, a mixing chamber, a water spray hole and a gas spray hole are formed in each spray head body; two ends of each mixing chamber are connected with the corresponding water inlet pipeline and the corresponding water spray hole; and each gas inlet channel and the corresponding gas spray hole are communicated and are communicated with the corresponding mixing chamber through a through hole. The dry fog box is delicate in structure, performs atomizing on liquid twice, namely gas-bubble atomizing and pneumatic atomizing, so that the whole dry fog box is filled with fog drops with diameter smaller than 2.5 mu m, and the dust removal effect is effectively improved.
Description
Technical field
The invention belongs to technical field of environment protection equipment, and in particular to a kind of dry fog case.
Background technology
In industrial and mining establishment, the improvement to dust is always a great problem.Count according to Ministry of Public Health, China's pneumoconiosis have become duty
Industry disease is the first, accounts for the 80% of total occupation disease.Dust in air, granular size is different, distribution is different.The master that dust suppression is administered
Will pair as if less than 150 μm of dust granules, especially particle diameter is less than 10 μm of respirable dust granule.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 even can float hundred kilometers of row sometimes, to people
The harm of body is especially big, is the main contributor for causing pneumoconiosis and atmospheric 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
Deviate from the air-flow for streaming and bump against with droplet and be captured, i.e., by the inertial collision of powder dust particle and drop, intercept and
The effects such as cohesion, diffusion are realized catching 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 with dust granules and seldom or is at all not in contact with, and does not reach dust suppression effect.Therefore, droplet
The whether sufficiently small effect for determining suppressing dust with dry mist of diameter.
The content of the invention
The purpose of the present invention is to propose to dry fog case, can be full of droplet of the diameter less than 2.5 μm in the dry fog case.
The technical scheme is that what is be achieved in that：A kind of dry fog case, including casing, the casing is provided with air inlet and goes out
QI KOU, is provided with some atomizers at the top of the casing, the atomizer includes sprayer body, and in the shower nozzle body water inlet pipe is provided with
Road, admission line, mixing chamber, hole for water spraying and fumarole, the two ends of the mixing chamber respectively with the inlet channel and hole for water spraying
It is connected, the admission line is connected with the fumarole and is connected with the mixing chamber by through hole.
The present invention operation principle be：Pressure and mixing chamber of the pressure in atomizer admission line more than inlet channel
Pressure, the compression stroke in admission line mixes and formed bubble into mixing chamber with water, and bubble is during two-phase flow
Accelerate, deform, expand, liquid is squeezed into thread in water spray aperture and is sprayed water in the extremely short distance in aperture, due to interior in leaving
The increase of external differential and drastically expand even blast, brin line is fried into into trickleer droplet；From the high speed that fumarole sprays
Form very high relative velocity between air-flow and droplet, produce very big frictional force, air-flow droplet is produced strong tear with
Shear action, droplet is so as to by secondary-atomizing, form the less droplet of diameter, while the speed of service of quickening 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 spray velocity faster.
More preferably, the quantity of the fumarole is 2～6, and ring is uniform.
More preferably, dividing plate is provided near described gas outlet one end, the bottom phase of the dividing plate and the casing in the casing
Every.The structure causes dust directly will not overflow 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.
Present configuration is ingenious, and liquid is atomized twice, i.e. effervescent atomization and pneumatic nebulization so that whole dry fog case
The interior droplet full of diameter less than 2.5 μm, effectively increases dust removing effects.
