The alleged problem of the utility model realizes with following technical scheme:
A kind of circular spray type spray nozzle, sprayer body and air inlet last and in it thereof are arranged in the formation, inlet, spout and vortex generator, its unique distinction is, described sprayer body is by housing 1, the air inlet pipe 2 that is arranged in housing 1 is formed, described vortex generator is by forming around the ring-shaped air chamber 3 of air inlet pipe 2 front end peripheries and the tangential spray orifice 4 that is arranged on the air inlet pipe front end tube wall, described spout is an annular jet 5, form by the annular space between the blanking cover 6 before ring-shaped air chamber 3 and the air inlet pipe, there is medium cavity volume 7 between housing 1 and the air inlet pipe 2, be distributed with pore 8 around ring-shaped air chamber 3 peripheries as inlet, the corresponding annular jet 5 of pore front end, tail end communicates with medium cavity volume 7, also is provided with medium import 9 on the housing 1.
Above-mentioned circular spray type spray nozzle, described air inlet pipe 2 front ends have flange 10, blanking cover 6 is made up of interior pipe 11 and enclosing cover 12 before described, interior pipe 11 tail ends are connected with flange 10, on the pipe 11, described ring-shaped air chamber 3 was formed by the annular space between interior pipe and the flange 10 in described tangential spray orifice 4 was arranged in, and described annular jet 5 is formed by the end face space between enclosing cover 12 and the flange 10, described pore 8 is arranged on the flange 10, and described housing 1 is that bowl-shape, the rim of a bowl docks with flange 10 sealings.
Above-mentioned circular spray type spray nozzle, the tail end of described air inlet pipe 2 are provided with fastening locknut 14, and described bowl-shape housing 1 docks with flange 10 sealings by fastening locknut 14.
Be the standard media flow, above-mentioned circular spray type spray nozzle, described pore 8 is arranged in the annular groove of setting up 13.
Above-mentioned circular spray type spray nozzle, the quantity of arranging of described tangential spray orifice 4 is 3～12, and the slit of described annular jet 5 is 1～3 millimeter, and the aperture of described pore 8 is 0.5～2 millimeter.
The utlity model has following characteristics:
1. annular jet is perpendicular to the direct of travel of gas, the gas liquid mixture of rotation changes direction towards shower nozzle 360 ° of comprehensive injections all around behind annular jet at a high speed, to form one be the very big covering circle at center with the nozzle, eliminated the direct injection nozzle can only injection nozzle the place ahead than the defective of zonule and can't adapt to the limitation that the inside pipe wall spraying is used;
Gas liquid mixture through annular jet by straightaway after the unexpected modified line to around during annular spray, pressure reduction increases before and after spraying, the corresponding increase of gas liquid mixture expansion dynamics, help the refinement of droplet, can increase the probability that combines of drop and elevated temperature vessel, gas and dusty gas, and then promote the cooling dust removing effects, can improve uniformity, the fineness of sprayed coating and save coating because of the drop refinement;
3. when sprayer body adopts the flanged version of water inlet pipe, made things convenient for the setting and the processing of tangential spray orifice, ring-shaped air chamber etc., made the structure of shower nozzle have more the simple characteristic of science;
4. when adopting pore to be arranged in circular groove structure, help coating such as thickness paint and concentrate to the pore place and gather, form evenly continuous MEDIA FLOW;
The utility model has been broken through the traditional design of direct injection shower nozzle, and a kind of brand-new circular spray type structure shower nozzle is provided, and has realized the purpose of this utility model, and suitable utensil as cooling, dedusting and sprayed protection coating uses.
