Description

Technical Field

[0001] The present application relates to the field of hydrogen peroxide flash evaporation devices, and in particular to a novel high-efficiency vaporization flash evaporation device. Background Art

[0002] Vaporized hydrogen peroxide (VHP) is a common disinfectant gas, typically produced from a hydrogen peroxide solution. Since hydrogen peroxide boils at 150°C, while water boils at 100°C, the difference between the two is significant. To produce VHP, a flash vaporization process is used in a flash evaporation unit to bring hydrogen peroxide and water to a boil simultaneously within a short period of time.

[0003] In existing related technologies, a flash evaporation device comprises an injector and a flash chamber. The flash chamber defines a flash chamber, which is heated and insulated by an external heating device. The injector is mounted within the flash chamber, with the injector's outlet located within the flash chamber. During VHP production, an external hydrogen peroxide solution delivery device delivers hydrogen peroxide solution to the injector's input and simultaneously delivers a carrier gas for transporting the VHP into the flash chamber. A single droplet of hydrogen peroxide solution is then injected into the flash chamber through the injector's output. After the droplet fully contacts the inner wall of the flash chamber, it undergoes a sudden vaporization phenomenon under the influence of the high temperature, producing VHP.

[0004] Regarding the above-mentioned related technologies, when the hydrogen peroxide solution delivery device delivers the hydrogen peroxide solution at a high rate, it is difficult for the syringe to maintain a single hydrogen peroxide solution droplet, making it difficult for the hydrogen peroxide solution droplet to fully contact the inner wall of the flash cavity, affecting the sudden vaporization of the hydrogen peroxide solution, and further affecting the production efficiency of VHP. Summary of the Invention

[0005] In order to ensure that a large amount of vaporized hydrogen peroxide can still be produced when the injection rate of the hydrogen peroxide solution is high, thereby ensuring the production efficiency of the vaporized hydrogen peroxide, the present application provides a new type of high-efficiency vaporization flash evaporation device.

[0006] The present application provides a novel high-efficiency vaporization flash evaporation device adopts the following technical solution:

[0007] A novel high-efficiency vaporization flash evaporation device comprises a flash evaporation box and a plurality of atomizing nozzles. A flash evaporation cavity is provided inside the flash evaporation box. The plurality of atomizing nozzles are installed in the flash evaporation box. The input ends of the plurality of atomizing nozzles are connected to an external hydrogen peroxide solution delivery device, and the output ends of the plurality of atomizing nozzles are located in the flash evaporation cavity. The plurality of atomizing nozzles are used to spray atomized hydrogen peroxide solution into the flash evaporation cavity.

[0008] By adopting the above technical solution, when the hydrogen peroxide solution injection rate is high, multiple atomizing nozzles simultaneously spray the atomized hydrogen peroxide solution into the flash cavity, thereby ensuring that the hydrogen peroxide solution can still fully contact the inner wall of the flash cavity. In addition, when the hydrogen peroxide solution injection rate is high, the atomizing nozzles are more likely to form hydrogen peroxide solution droplets with smaller particle size, further ensuring that the hydrogen peroxide solution can still fully contact the inner wall of the flash cavity, thereby maintaining the production efficiency of vaporized hydrogen peroxide.

[0009] Optionally, a heating block is provided in the flash evaporation cavity, and the heating block divides the flash evaporation cavity into an input cavity, a connecting cavity and an output cavity. The output end of the input cavity is connected to the input end of the connecting cavity, and the output end of the connecting cavity is connected to the output cavity. The output ends of several of the atomizing nozzles are all located in the input cavity.

[0010] By adopting the above technical solution, the heating block heats the flash evaporation cavity, which is conducive to ensuring the stability of the temperature of the flash evaporation cavity. In addition, by dividing the flash evaporation cavity into an input cavity, a connecting cavity, and an output cavity, the delivery path of the hydrogen peroxide solution is extended, thereby ensuring that the hydrogen peroxide solution can fully contact the flash evaporation cavity and undergo sudden vaporization.

[0011] Optionally, the heating block is provided with a heating slope, and the heating slope is arranged toward the output end of the atomizing nozzle.

[0012] By adopting the above technical solution, the heating slope increases, making it easier for the hydrogen peroxide solution to contact the heating block, thereby making it easier for the hydrogen peroxide solution to undergo sudden vaporization.

[0013] Optionally, the flash evaporation box is provided with a flash evaporation input port, which is used to deliver carrier gas to the flash evaporation box, an output end of the flash evaporation input port is connected to the input cavity, and the flash evaporation input port is arranged toward the heating inclined surface.

[0014] By adopting the above technical solution, during the flow of the carrier gas, the atomized hydrogen peroxide solution is easily blown toward the heating inclined surface, thereby making it easier for the hydrogen peroxide solution to undergo sudden vaporization.

[0015] Optionally, the output cavity is provided with an output inclined surface, and the output inclined surface is arranged toward the output end of the communicating cavity.

[0016] By adopting the above technical solution, the transport path of the hydrogen peroxide solution is extended, thereby ensuring that the hydrogen peroxide solution can fully contact the flash cavity and cause sudden vaporization.

[0017] Optionally, the flash evaporation box is provided with a flash evaporation input port, the output end of the flash evaporation input port is connected to the flash evaporation cavity, the input end of the flash evaporation input port is connected to a carrier gas heater, and the carrier gas heater is used to heat the carrier gas entering the flash evaporation cavity.

[0018] By adopting the above technical solution, the carrier gas heater heats the carrier gas, which on the one hand enables the carrier gas to carry more hydrogen peroxide, and on the other hand makes it difficult for the vaporized hydrogen peroxide solution to condense and precipitate due to carrier gas saturation.

[0019] Optionally, the carrier gas heater is connected to a thermometer.

[0020] By adopting the above technical solution, it is convenient for production personnel to observe the temperature inside the carrier gas heater, and thus adjust the temperature of the carrier gas heater in a timely manner.

[0021] Optionally, the heating slope is arranged in an arc shape, and the output ends of the plurality of atomizing nozzles are all located within the area enclosed by the heating slope.

[0022] By adopting the above technical solution, the atomized hydrogen peroxide solutions produced by the plurality of atomizing nozzles can fully contact the heating inclined surface, thereby ensuring the production efficiency of the vaporized hydrogen peroxide.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the hydrogen peroxide solution injection rate is high, multiple atomizing nozzles simultaneously spray the atomized hydrogen peroxide solution into the flash cavity, thereby ensuring that the hydrogen peroxide solution can still fully contact the inner wall of the flash cavity. In addition, when the hydrogen peroxide solution injection rate is high, the atomizing nozzles are more likely to form hydrogen peroxide solution droplets with smaller particle size, further ensuring that the hydrogen peroxide solution can still fully contact the inner wall of the flash cavity, thereby ensuring the production efficiency of vaporized hydrogen peroxide;

[0025] 2. The heating block heats the flash cavity, which helps to ensure the temperature stability of the flash cavity. By dividing the flash cavity into an input cavity, a connecting cavity, and an output cavity, the delivery path of the hydrogen peroxide solution is extended, thereby ensuring that the hydrogen peroxide solution can fully contact the flash cavity and undergo sudden vaporization.

[0026] 3. The carrier gas heater heats the carrier gas, which, on the one hand, enables the carrier gas to carry more hydrogen peroxide, and on the other hand, prevents the vaporized hydrogen peroxide solution from condensing and precipitating due to carrier gas saturation.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Example 1:

[0035] Example 1 of the present application discloses a novel high-efficiency vaporization flash evaporation device. Figure 1 and Figure 2 The novel high-efficiency vaporization flash evaporation device includes a flash evaporation box 1 and a plurality of atomizing nozzles 2. The flash evaporation box 1 is heated by an external heating device, and in Example 1 of the present application, the number of atomizing nozzles 2 is set to three, and the three atomizing nozzles 2 are equidistantly distributed in a direction perpendicular to the carrier gas delivery direction.

[0036] Reference Figure 3 The flash chamber 1 is provided with a flash cavity, a flash input port 201, and a flash output port 202. The flash input port 201 and the flash output port 202 are both connected to the flash cavity, and the flash input port 201 and the flash output port 202 are respectively located on either side of the flash cavity. The input end of the flash input port 201 is connected to a carrier gas heater 3. The carrier gas heater 3 heats the carrier gas entering the flash cavity through its own heating wire. On the one hand, this allows the carrier gas to carry more hydrogen peroxide, and on the other hand, it prevents the vaporized hydrogen peroxide solution from condensing and precipitating due to carrier gas saturation. In addition, the carrier gas heater 3 is connected to a thermometer 31 to facilitate production personnel to observe the temperature inside the carrier gas heater 3.

[0037] A heating block 11 is provided within the flash evaporation cavity and is fixedly connected to the flash evaporation housing 1. The heating block 11 divides the flash evaporation cavity into an input cavity 101, a connecting cavity 102, and an output cavity 103. The input end of the input cavity 101 is connected to the output end of the flash evaporation input port 201, the output end of the input cavity 101 is connected to the input end of the connecting cavity 102, and the output end of the connecting cavity 102 is connected to the output cavity 103. The output ends of a plurality of atomizing nozzles 2 are all located within the input cavity 101, and the atomizing nozzles 2 are all used to spray atomized hydrogen peroxide solution into the flash evaporation cavity, so that a carrier gas is input into the flash evaporation input port 201, thereby transporting vaporized hydrogen peroxide (VHP) to the input cavity 101, the connecting cavity 102, the output cavity 103, and the flash evaporation outlet in sequence.

[0038] Reference Figure 3 The heating block 11 is provided with a heating bevel 111, which is arranged flat and faces the output end of the atomizing nozzle 2. The vertical projection area of the atomizing nozzle 2 is located within the vertical projection area of the heating bevel 111, and the flash evaporation input port 201 is arranged toward the heating bevel 111. This allows the atomized hydrogen peroxide solution to fully contact the heating bevel 111 through the carrier gas, thereby making it easier for the hydrogen peroxide solution to undergo sudden vaporization. In addition, the output cavity 103 is provided with an output bevel 104, which is arranged toward the output end of the connecting cavity 102. This extends the delivery path of the hydrogen peroxide solution, thereby ensuring that the hydrogen peroxide solution can fully contact the flash evaporation cavity and undergo sudden vaporization.

[0039] The implementation principle of a novel high-efficiency vaporization flash evaporation device in Example 1 of the present application is as follows: after being heated by the heating wire of the gas heater, the carrier gas passes through the flash evaporation input port 201, the input cavity 101, the connecting cavity 102, the output cavity 103, and the flash evaporation output port 202 in sequence. After the atomizing nozzle 2 produces atomized hydrogen peroxide solution, the atomized hydrogen peroxide solution, due to its small droplet size, fully contacts the heating inclined surface 111 and the inner wall of the flash evaporation cavity, and undergoes a sudden vaporization phenomenon to form VHP, which is then transported to the flash evaporation output port 202 by the carrier gas. In addition, when the injection rate of the hydrogen peroxide solution is high, the atomized hydrogen peroxide solution is simultaneously sprayed into the flash evaporation cavity through multiple atomizing nozzles 2, thereby ensuring that the hydrogen peroxide solution can still fully contact the inner wall of the flash evaporation cavity and produce a large amount of VHP, thereby ensuring the production efficiency of vaporized hydrogen peroxide.

[0040] Example 2:

[0041] Example 2 of the present application discloses a novel high-efficiency vaporization flash evaporation device, which differs from Example 1 mainly in that the specific arrangement of the heating slope 111 of the heating block 11 is different. Figure 4 and Figure 5 The heating slope 111 is arranged in an arc shape, and the output ends of the plurality of atomizing nozzles 2 are all located within the area enclosed by the heating slope 111, so that the atomized hydrogen peroxide solutions produced by the plurality of atomizing nozzles 2 can fully contact the heating slope 111, thereby ensuring the production efficiency of vaporized hydrogen peroxide.

[0042] The implementation principle of Example 2 of the present application is the same as that of Example 1 and will not be repeated here.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
