Description
Technical field
The invention belongs to technical field of environment protection equipment, and in particular to a kind of suppressing dust with dry mist equipment.
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 has turned 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
Will pair as if less than 150 μm of dust granules, especially particle diameter is less than 10 μm of respirable dust particle.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 the main contributor for causing pneumoconiosis and 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
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.Dry fog machine is the core component of suppressing dust with dry mist equipment, existing dry fog
Machine can not precisely be adjusted to output and hydraulic pressure, air pressure, and safeguard inconvenient.
The content of the invention
The purpose of the present invention is suppressing dust with dry mist equipment, and the water yield and water outlet outlet of dry fog machine can be precisely adjusted as needed
