Abstract
The utility model relates to an airflow type multiple passage atomizer. A nozzle core [2], feed liquid passages [3] and an air passage [4] are arranged on a nozzle [1]. The feed liquid passages [3] and the air passage [4] are separately connected with a feed pipe [6] and an air inlet pipe [9]. The feed liquid passages [3] are at least arranged in one pair and are symmetrically arranged on both sides of the nozzle core [2]. The air passage [4] is symmetrically arranged on the outward position of the feed liquid passage [3] and is correspondingly matched with the feed liquid passages [3]. Front end outlets of the air passage [4] and each feed liquid passage [3] which are matched in the same direction are corresponding and are arranged in the front of the nozzle core [2]. The utility model has the advantages of little corollary equipment and ideal atomizing granulation effect and is suitable for being used for atomizing liquid materials without solid particles and for spray drying devices.
Description
Technical field
The utility model relates to a kind of spray-drying installation, is a kind of air-flowing type multichannel atomizer specifically.
Background technology
Spray-drying installation is widely used in petrochemical industry and other industrial production, in spray-drying installation, the atomizing effect of atomizer directly influences the granulation effect, and atomizer structure is relevant with its required corollary equipment, therefore optimize the structure of atomizer, not only can improve its atomizing granulation effect, also can reduce relevant equipment input, thereby reduce cost and relevant maintenance cost.Existing atomizer is many, and air-flowing type, pressure type, rotary, electrostatic etc. are arranged.Wherein the corollary equipment of pressure type, rotary, electrostatic atomizer needs is many, and power consumption is big, and input ratio is bigger; And pneumatic atomizer is two fluid-types or three fluid-types, and their hybrid mode all is that interior earlier mixing outside the back mixed, and the compressed-air power consumption that is used to atomize is bigger, and treating capacity is little, and the granulation effect that atomizes is not ideal enough.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved air-flowing type multichannel atomizer is provided, and not only treating capacity is big for it, and power consumption is less, and the atomizing granulation is satisfactory for result.
The purpose of this utility model can realize by following technical measures: on the nozzle of this atomizer nozzle core is arranged, the feed liquid passage, air duct, the feed liquid passage, air duct connects feed pipe respectively, air inlet pipe, described feed liquid passage is provided with a pair of at least, be symmetrical arranged on the nozzle core both sides, the air duct symmetry is located at the export-oriented position of feed liquid passage, match with the feed liquid passage is corresponding, the air duct that matches in the same way, feed liquid passage front end exit correspondence, be opened in the nozzle core forward position, the top angle of nozzle core is 45～55 °, and the fluid that feed liquid passage and air duct come out is along the top point of intersection of nozzle core.
Described feed liquid passage, air duct are long narrow slit shape along the exit trend.
The air inlet pipe periphery can be set up storage heater, the effect of drying when hot-air is strengthened atomizing.
After adopting above-mentioned measure, this atomizer is the structure of multithread body channel-type, and each fluid passage all is long narrow slit shape, feed liquid, takes their own roads through the air of heating, converges at the top collision type of nozzle core to produce strong atomizing.
The utility model is reasonable in design, before atomizing air is heated and can realize rapid draing; Multithread body passage can improve treating capacity; At the top collision type of the nozzle core raising mixed effect that crosses, thereby vaporific raw material wink-dry is improved its granulation effect.The liquid material that this atomizer is suitable for not containing solid particle atomizes.It is simple in structure, and required corollary equipment is few, is the more satisfactory atomizer of spray-drying installation.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
With reference to Fig. 1, this atomizer comprises nozzle [1], nozzle core [2] both sides symmetry offers two feed liquid passages [3], and symmetry offers two air ducts [4], and air duct [4], feed liquid passage [3] can be established two pairs as required, even it is more, air duct [4] is located at the export-oriented position of feed liquid passage [3], with feed liquid passage [3] corresponding matching, and the air duct that matches in the same way [4], feed liquid passage [3] front end exit correspondence, be opened in nozzle core [2] forward position, the top angle of nozzle core [2] is 50 °.
Feed liquid passage [3] connects feed pipe [6] by feed-inputing branched pipe [5]; Air duct [4] connects air inlet pipe [9] by air intake branch [7], is provided with storage heater [8] in air inlet pipe [9] periphery, and storage heater [8] is an electric heater.
Claims (4)
