A sprayer and temperature and humidity sensors are installed inside the spray drying tower.

[0021] The sprayer includes a housing 1 and a cover plate 2, with the cover plate 2 installed on the upper end of the housing 1. The housing 1 is characterized by having a first swirling chamber 3 and a second swirling chamber 4. The first swirling chamber 3 and the second swirling chamber 4 are separated by a dividing wall 5 and are fluidly connected only through a connecting channel 6, which is approximately tangent to the outer periphery of both chambers. The outer periphery of the first swirling chamber 3 has a liquid inlet 7 that is approximately tangent to it. A first swirling impeller assembly 8 is rotatably installed inside the first swirling chamber 3, and a second swirling impeller assembly 9 is rotatably installed inside the second swirling chamber 4. The liquid inlet 7 is connected to a delivery pump via a second pipeline, a control valve, and a flow sensor.

[0022] The first swirling impeller assembly 8 includes a first rotating shaft 81, a first blade 82, and a first bearing 83. The outer circumferential surface of the first rotating shaft 81 is connected to a plurality of first blades 82 distributed along the circumferential direction. The upper and lower ends of the first rotating shaft 81 are respectively connected to the cover plate 2 and the lower end of the housing 1 through the first bearing 83. The first swirling impeller assembly 8 can rotate in the first swirling cavity 3 under the impact of the liquid.

[0023] The second swirl impeller assembly 9 includes a second rotating shaft 91, second blades 92, and a second bearing 93. Multiple second blades 92 distributed circumferentially are connected to the outer circumferential surface of the second rotating shaft 91. The upper end of the second rotating shaft 91 is connected to the cover plate 2 through the second bearing 93, and the lower end is suspended. A spray nozzle 10 is provided at the lower end of the housing 1. The spray nozzle 10 is located directly below the second rotating shaft 91. The second swirl impeller assembly 9 can rotate in the second swirl chamber 4 under the impact of the liquid.

[0024] The present invention, through the structural design of the sprayer, specifically, allows the first swirl impeller assembly 8 to rotate within the first swirl chamber 3 under the impact of the liquid, and the second swirl impeller assembly 9 to rotate within the second swirl chamber 4 under the impact of the liquid, so that the liquid is in a swirling and stirring state, which can ensure the uniformity of the liquid concentration; and through the design of the two-stage swirl impeller assembly, the liquid has higher swirling performance, which can improve the uniformity of the spray and improve the spray / spray granulation efficiency.

[0025] In a preferred embodiment, a first drive wheel 84 is installed at the upper end of the first rotating shaft 81, and a first nut 85 is installed at the upper end of the first drive wheel 84.

A cover 12 is installed above the cover plate 2. The first drive wheel 84, the second drive wheel 94, and the drive chain / drive belt 97 are disposed inside the cover 12.

[0026] This invention, through the design of the transmission components, specifically, connects the first transmission wheel 84 and the second transmission wheel 94 via a transmission chain / belt 97, and according to a preset transmission ratio, enables the first swirl impeller assembly 8 and the second swirl impeller assembly 9 to have a preset relative rotational speed, such as a preset transmission ratio / speed difference between the first swirl impeller assembly 8 and the second swirl impeller assembly 9, and to accelerate or decelerate at the same speed. The rotational speed of the first swirl impeller assembly 8 and the second swirl impeller assembly 9 can be controlled by controlling the flow rate and / or pressure of the liquid in the inlet hole 7, and the flow rate and / or pressure of the liquid in the inlet hole 7 can be adjusted and controlled by the control valve on the second pipeline. This allows for automatic control and ensures that the liquid has higher swirling performance, thereby improving the uniformity of the spray and increasing the spray / spray granulation efficiency.

[0027] The lower end of the second swirling chamber 4 is provided with a conical section 11, the lower end of which is connected to the spray nozzle 10. The lower end of the second rotating shaft 91 is connected to a guide cone 96, the taper of which is consistent with the taper of the conical section 11, which can improve the swirling and guiding effect of the conical section 11.

[0028] In one embodiment, there is an eccentricity difference g between the axis of the first swirl impeller assembly 8 and the axis of the first swirl cavity 3, and the axis of the first swirl impeller assembly 8 is positioned closer to the connecting channel 6.
