Embodiment

[0025] Such as figure 1 As shown, a two-fluid atomizing nozzle includes a distribution seat 1 and a nozzle 4, the middle position of the distribution seat 1 is provided with a material hole 11, and the periphery of the material hole 11 is provided with a ventilation hole 12, such as figure 2 and image 3 As shown, the material hole 11 is located in the middle of the distribution seat 1 and runs through the distribution seat 1 , and there are eight ventilation holes 12 evenly distributed around the material hole 11 , and the ventilation holes 12 also pass through the distribution seat 1 . The distribution seat 1 is fixedly connected with the nozzle 4 by a nut 2, and a material mixing tank 41 is formed in the nozzle 4, and the material hole 11 and the ventilation hole 12 are both communicated with the material mixing tank 41. Such as Figure 6 As shown, the nozzle 4 is also provided with a nozzle 42 . An inner chamber 13 is embedded at the outlet of the material hole 11 towa...

Abstract

The invention discloses a two-fluid atomizing nozzle used in spray drying equipment. The two-fluid atomizing nozzle comprises a distribution base and a nozzle, wherein the distribution base and the nozzle are fixed by a screw cap; an adjustable spray core is arranged between the distribution base and the nozzle; and the liquid distribution is realized by the spray core. The liquid spraying angle is increased through the spray core, so that the atomizing diameter is bigger, and the particle size is smaller; and the liquid is instantly dried after being contacted with hot air, so that the water content is lower, the heat exchanger between fog drops and the hot air is more sufficient, and the agglomeration phenomenon is prevented.

Description

technical field [0001] The invention relates to a two-fluid atomizing nozzle used in spray drying equipment. Background technique [0002] The special internal structure design of the two-fluid atomizing nozzle can make the liquid and gas mix evenly, and realize the gas-liquid mixed atomization. In the antibiotic spray drying production process, the two-fluid nozzle is installed at the top of the drying tower to connect with the two-fluid atomizer. In the actual production process, the feed liquid is easily in contact with the cone of the tower body after being sprayed from the nozzle, resulting in a small amount of feed liquid falling into the bottom of the tower after being completely dried, which may cause tower sticking or high water content in the finished product. The reason is that the nozzles in the prior art can adjust the atomization angle in a too small range, resulting in a short contact time between the material and the hot air, resulting in insufficient heat e...
