Problems solved by technology
[0003] In view of the problem that the existing atomizer nozzles are easy to wear, the present invention proposes a new type of atomizer nozzle. The nozzle of the new atomizer is provided with a high-pressure air chamber, and after the high-pressure airflow enters the high-pressure air chamber through the air inlet, It is sprayed at high speed from the narrow air outlet, and forms a high-speed airflow on the wall of the inner hole of the nozzle. When the slurry is sprayed out through the inner hole of the nozzle to form droplets, it does not contact the wall of the inner hole of the nozzle, so the slurry will not wear the nozzle. Increased service life of atomizer nozzles

Embodiment Construction
[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0010] The present invention proposes a novel atomizer nozzle, which consists of an air inlet 1, a high-pressure air chamber 2, a narrow air outlet 3, a slurry inlet 4, a nozzle inner hole 5, and a droplet outlet 6. The air outlet 3 is located at the slurry inlet 4, the angle α between the opening direction of the narrow air outlet 3 and the generatrix of the inner hole wall of the nozzle is an acute angle, and 0°<α<45°, the high-pressure airflow enters the high-pressure air chamber through the air inlet 1 After 2, it is ejected at a high speed from the narrow air outlet 3, and a high-speed airflow layer is formed on the hole wall of the nozzle inner hole 5. It is not in contact with the hole wall of the inner hole 5 of the nozzle, so the slurry will not wear the nozzle, and the service life of the nozzle of the atomizer is improved. ...

The invention discloses a desulphurization atomizer gas flow nozzle, and belongs to environment-friendly equipment. The atomizer nozzle is composed of a gas inlet, a high-pressure gas chamber, a narrow gas outlet, a fluid inlet, an inner nozzle hole and a fog drop outlet, wherein the narrow gas outlet is formed in the fluid inlet, the included angle between the opening direction of the narrow gas outlet and the axis of the nozzle is an acute angle, high-pressure gas flow enters the high pressure gas chamber through the gas inlet, then is sprayed out through the narrow gas outlet at a high speed, and forms a high speed gas flow layer on the hole wall of the inner nozzle hole, and when fluid reaches the frog drop outlet from the fluid inlet through the inner nozzle hole to form frog drops to be sprayed out, the fluid does not make contact with the hole wall of the inner nozzle hole, and thus the nozzle will not be abraded by the fluid. Through optimization on the structural design of the nozzle, the atomizer nozzle has the advantages of being high in abrasion resistance, corrosion resistance and long in service life.
Description
technical field [0001] The invention belongs to environmental protection equipment, in particular to an air flow nozzle of a desulfurization atomizer, which is mainly used in environmental protection desulfurization and dust removal and spraying and washing in tower equipment in the chemical industry. Background technique [0002] When the high-speed rotary atomizer of the desulfurization system of the sintering machine in the ironworks sprays the desulfurizer slurry, the slurry generates tiny droplets under the action of centrifugal force and is thrown outward to form a desulfurization atomization area. The atomizer nozzle is installed in the high-speed rotating mist On the atomizer wheel, the rotation speed of the atomizer is 9000 rpm. The slurry in the atomizer wheel is thrown out from the nozzle to form mist droplets. The fluid passing through the atomizer nozzle contains 20% solid particles. The atomizer nozzle It is easy to wear and tear, and the cost of replacing the ...
