Description

Technical Field

[0001] This utility model relates to the field of steam system de-cooling, specifically a rotary atomizing nozzle. Background Technology

[0002] With technological advancements, atomizing devices are widely used in agriculture, industry, environmental control, and daily life. In agriculture, they are used for pesticide spraying and greenhouse humidification; in industry, they are used for cooling and dust removal; and in environmental control, they are used for dust suppression and landscape fogging. The rotary atomizing nozzle is the core component of the atomizing device, and its performance directly determines the diameter of the atomized droplets, thus determining the atomization effect. Existing rotary atomizing nozzles mostly operate on the principle of being driven by an electric fan, utilizing the Venturi principle to draw in air at high speed. Sufficient kinetic energy is provided to the air within the nozzle, causing the gas to collide with droplets at high speed, producing dry mist particles, which then overflow as dry mist particles.

[0003] Chinese invention patent application No. 201810533700.5 proposes a novel rotating atomizing nozzle. The outer surface of the bottom wall of the atomizing chamber facing the air outlet of the fan is a conical surface. Several through holes are evenly arranged circumferentially on the outer surface of the conical surface. The through holes are set at a certain angle relative to the radial direction. The inner end of the through holes is connected to the atomizing chamber and the outer end is connected to the air outlet of the fan. The bottom wall is provided with an outlet hole in the middle, which is connected to the liquid outlet pipe.

[0004] The aforementioned rotating atomizing nozzle operates on the principle of pneumatic atomization, which uses compressed air to generate a high-speed airflow to disperse the liquid into small particles. It is suitable for applications requiring rapid evaporation and mixing. However, this type of atomizing equipment requires an electric fan connected to it, which is housed inside the casing, thus increasing costs and complicating the structure.

[0005] Therefore, this project aims to design a simple, easy-to-manufacture, energy-saving and environmentally friendly rotary atomizing nozzle that allows liquid to pass through a specially designed nozzle orifice under high pressure or high-speed airflow. Summary of the Invention

The several first water inlets are located on the side of the atomizing plate away from the collecting plate, and the guide groove is located on the side of the atomizing plate close to the collecting plate. The guide groove includes a central hole and several water channels tangent to the central hole at the same clockwise direction.

[0025] This utility model embodiment provides a rotating atomizing nozzle, such as Figure 1-5 As shown, the device includes a nozzle housing 1, an atomizing plate 2, and a collector plate 3. The nozzle housing 1 is made of metal and machined. The nozzle housing 1 is open at both ends, with one end connected to a water pipe 8, and the atomizing plate 2 and collector plate 3 sequentially installed at the other end. After the atomizing plate 2 and collector plate 3 are stacked, several sets of atomizing channels are formed on them. Each atomizing channel includes several first water inlets 41, guide grooves 42, and collecting holes 43. The first water inlets 41 are located on the side of the atomizing plate 2 away from the collector plate 3, and the guide grooves 42 are located on the side of the atomizing plate 2 near the collector plate 3. On one side, the flow channel 42 includes a central hole 421 and several water channels 422 that are tangent to the central hole 421 at the same clockwise direction. The end of the water channel 422 is a second water inlet 423. The second water inlet 423 is connected to the first water inlet 41. The central hole 421 is connected to the collecting hole 43. The water flow direction is water pipe 8, first water inlet 41, second water inlet 423, water channel 422, central hole 421, and collecting hole 43. The modular design of the nozzle shell 1, atomizing plate 2 and collecting plate 3 is conducive to better processing and assembly, and facilitates mass production.

[0026] In selecting the atomizing channels, a reasonable arrangement is required, taking into account the space utilization rate. In this embodiment, it is preferred that the atomizing channels are in three groups, each group of atomizing channels includes two first water inlets 41 and one collection hole 43, with the collection holes 43 arranged on the same circumference.

[0027] like Figure 2 and Figure 4 As shown, preferably, the diameter of the intermediate hole 421 is larger than the diameter of the second water inlet hole 423.

[0028] Regarding the installation method of the nozzle housing 1 with the atomizing plate 2 and the collector plate 3, the preferred method in this embodiment is as follows: Figure 1 As shown, a stepped hole is provided at one end of the nozzle housing 1. The depth of the stepped hole is adapted to the thickness of the atomizing plate 2 and the collector plate 3. After the atomizing plate 2 and the collector plate 3 are installed in sequence, they are welded and fixed to the nozzle housing 1.

[0029] Regarding the connection method between the nozzle housing 1 and the water pipe 8, in this embodiment, it is preferred that the nozzle housing 1 has an internal thread in the opening at one end connected to the water pipe 8 for threaded connection with the end of the water pipe 8.

[0030] like Figure 3 As shown in the embodiment of this case, the cross-section of the collecting hole 43 is an isosceles trapezoid, and the diameter of the collecting hole 43 gradually decreases outward, which has a pressurization process for the water flow. In this way, when the water flow is sprayed from the collecting hole 43, it can better release pressure and generate mist.

[0031] like Figure 6 As shown, a wastewater spraying device employs a rotary atomizing nozzle, applied in the wastewater treatment process. The device utilizes a multi-planetary spray nozzle and includes a reaction chamber 5 through which high-temperature steam flows. A connecting pipe 6 is inserted into the reaction chamber 5, with its upper end connected to a water pipe 8 via a long flange 7. The lower end of the water pipe 8 enters the reaction chamber 5, and the connector is angled. The end of the water pipe 8 connects to the connector. Liquid water with a pressure higher than that of the steam is passed through the water pipe 8 to the multi-planetary spray nozzle, forming atomized fine droplets that mix with the high-temperature steam. This process ensures thorough mixing with the steam, 1. rapidly reducing the temperature of the steam requiring cooling, and 2. instantly converting the fine water droplets into steam, further purifying the vaporized wastewater (vaporization crystallization).

[0032] Working principle: When the rotating atomizing nozzle is in use, such as Figure 3As shown, high-pressure water flows through the first inlet hole 41 to the second inlet hole 423, and then flows into the middle hole 421 from the water tank 422. Since the water tank 422 and the middle hole 421 are tangent at the same clockwise direction, a high-pressure rotating water flow is formed. The high-pressure rotating water flow flows through the middle hole 421 and then through the collecting hole 43. With the collecting hole 43 arranged with a diameter from large to small, the water pressure is further increased. At the moment of spraying at the end of the collecting hole 43, the high-pressure rotating water flow suddenly releases pressure and forms a spray.

[0033] In summary, the rotary atomizing nozzle includes a nozzle housing 1, an atomizing plate 2, and a collector plate 3. The nozzle housing 1 is open at both ends, with one end connected to a water pipe 8, and the atomizing plate 2 and the collector plate 3 installed sequentially at the other end. Several sets of atomizing channels are formed on the atomizing plate 2 and the collector plate 3. The atomizing channels include several first water inlets 41, guide grooves 42, and collector holes 43. The guide grooves 42 include second water inlets 423, water tanks 422, and intermediate holes 421. The water tanks 422 and the intermediate holes 421 are tangent to each other clockwise. After the high-pressure liquid enters the several atomizing channels, the water flow is rotated under high pressure by the several guide grooves 42, and then sprayed out through the collector holes 43 to form atomized liquid. The rotary atomizing nozzle has a simple structure, is easy to manufacture, and is energy-saving and environmentally friendly.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
