Abstract

PURPOSE:To atomize water droplets and dry them completely even in the case of spraying water under low pressure, by tapering the forward end of a nozzle means consisting of a pressure nozzle for ejecting raw liquid and a cylindrical body for blowing off gases at a high speed disposed concentrically around the pressure nozzle. CONSTITUTION:A cylindrical body 3 for blowing off gases at a high speed is disposed concentrically around a pressure nozzle 6 for ejecting raw liquid to form a nozzle means, the forward end of which is formed into a tapered construction. As a result, even when water is sprayed under low pressure, droplets are atomized and dried completely, and further the spray nozzle is cooled to prevent the nozzle from becoming clogged. Consequently, in a spray drier equipped with this nozzle means, atomization of raw liquid, after spraying water under low pressure, can be performed effectively and stably.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nozzle device that can handle low-pressure spraying at the start of operation of a spray dryer, and a spray dryer device equipped with the nozzle device.

[Prior Art] Normally, in a spray dryer, it is necessary to stabilize the temperature inside the spray drying chamber at the start of operation to prevent the product from burning due to overheating and to protect the product from heat in subsequent processes. For that purpose, water is sprayed by the same pressure nozzle.

When such water spraying is performed, the amount of water sprayed needs to be equivalent to the water content in the stock solution. The moisture content of the stock solution is generally 30 to 80%, so the amount of water sprayed is similarly 30 to 80% of the specified spray amount of the stock solution.Due to the characteristics of the pressure nozzle, the pressure is approximately 30% to 80%, although it depends on the viscosity of the liquid It decreases to 10-80%. Therefore, due to the characteristics of the pressure nozzle, the water droplets become large particles and are difficult to dry, so they adhere to the interior of the drying chamber undried, and the walls become wet. At this time, if the stock solution is subsequently sprayed, the dried powder will adhere to that area and solidify.

Figure 6 shows an example of a case where multiple nozzles are installed. When multiple nozzles 10 are installed in the northern part of the spray drying chamber to perform water spraying, low pressure spraying can be achieved by controlling the number of IIa"R nozzles 10. It is something that is being avoided.
