Description

Technical Field

[0001] The invention relates to the technical field of ozone generators, in particular to a double water-cooled enamel ozone generator. Background Art

[0002] Ozone is a strong oxidant that can sterilize, decolorize and deodorize. One of its most important advantages as a strong oxidant is that it can decompose and reduce to oxygen in a short time. After sterilizing the environment, water, air, equipment and food, ozone will not leave any secondary pollutants that are harmful to the human body. Therefore, ozone has become an ideal universal green strong oxidant, playing a huge and irreplaceable role in environmental issues such as air and water treatment.

[0003] There are several methods for artificially producing ozone according to the principle: photochemical method, electrochemical method, atomic radiation method and corona discharge method. Industrial application of oxygen as raw material gas source mostly adopts corona discharge method to produce ozone. At present, the devices for producing ozone by corona discharge have tubular, flat plate and other different structures in structure, and their working principles are basically the same.

[0004] Among them, the enamel ozone generator belongs to a tubular corona discharge device. The enamel ozone generator usually includes an outer shell, an enamel tube and a sealing cover. The outer shell is tubular, and the enamel tube is arranged inside the outer shell at intervals. The outer shell serves as an outer electrode, and the enamel tube serves as an inner electrode. A discharge chamber (i.e., an air cavity or an air gap) is formed between the outer shell and the enamel tube. The sealing cover is arranged at the end of the outer shell. The sealing cover is provided with an ozone exhaust port connected to the discharge chamber. The ozone exhaust port runs through the upper and lower end surfaces of the sealing cover. When working, raw gas with a certain oxygen component enters the discharge chamber, and an AC voltage is applied to the inner and outer electrodes to form a corona discharge in the discharge chamber. The raw gas flowing through the discharge chamber is ionized under the action of the corona discharge to generate ozone, and the ozone in the discharge chamber is discharged outward through the ozone exhaust port of the sealing cover.

[0005] However, the existing above-mentioned enamel ozone generator has the following technical problems: the enamel ozone generator generates a large amount of heat when working, and the existing outer shell and enamel tube have poor cooling effect, resulting in the inability to effectively discharge the heat in the enamel ozone generator, which easily causes the generated ozone to decompose in the discharge chamber before it is effectively utilized, that is, affects the concentration of ozone.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides a double water-cooled enamel ozone generator, comprising an outer shell 1, an enamel tube 9 and a sealing cover 2. The outer shell 1 is tubular, the enamel tube 9 is arranged at intervals inside the outer shell 1, a discharge chamber is formed between the inner wall of the outer shell 1 and the outer wall of the enamel tube 9, and the sealing cover 2 is arranged at the end of the outer shell 1. The sealing cover 2 is provided with an ozone discharge port 3 connected to the discharge chamber, and the ozone discharge port 3 penetrates the upper and lower end surfaces of the sealing cover 2. The tube wall of the outer shell 1 is a double-layer structure, and a cavity 10 is formed inside the tube wall of the double-layer structure. The outer shell 1 is provided with a first water inlet 11 and a first water outlet 12 connected to the cavity 10, and the integrated double-layer structure can better prevent the cooling water of the cavity 10 from leaking out; the two ends of the enamel tube 9 are respectively provided with a second water inlet 13 and a second water outlet 14, and the inside of the enamel tube 9 is connected to the second water inlet 13 and the second water outlet 14.

[0030] It can be understood that the cooling water enters the cavity 10 of the outer shell 1 through the first water inlet 11, and the cooling water is used to cool the outer shell 1 by water cooling, and the cooling water that absorbs heat flows out from the first water outlet 12; in addition, the cooling water enters the interior of the enamel tube 9 through the second water inlet 13, and the enamel tube 9 is cooled by water cooling, and the cooling water that absorbs heat flows out from the second water outlet 14. In the above manner, the enamel ozone generator of the present invention adopts a double water cooling structure of internal water cooling (i.e., the enamel tube 9 is water cooled) plus external water cooling (i.e., the outer shell 1 is water cooled), which can better ensure the cooling effect of the enamel ozone generator, so as to better discharge the heat in the enamel ozone generator, so that the generated ozone is not easy to decompose and avoid affecting the concentration of ozone.

[0031] Preferably, the first water inlet 11 and the first water outlet 12 are both sealed and welded with the outer shell 1 to form a closed space; the first water inlet 11 is arranged near the lower end of the outer shell 1, and the first water outlet 12 is arranged near the upper end of the outer shell 1, that is, the cooling water enters the cavity 10 from the lower part of the outer shell 1 and overflows from the upper part of the outer shell 1, so that the entire cavity 10 can be filled with cooling water and then overflow from the upper part, which can better avoid the situation of dry burning due to lack of water, so as to ensure the water-cooled heat dissipation and cooling effect of the outer shell 1. In addition, preferably, the second water inlet 13 is arranged at the lower end of the enamel tube 9, and the second water outlet 14 is arranged at the upper end of the enamel tube 9, which can also better make the interior of the enamel tube 9 filled with cooling water and then overflow from the upper part, so as to ensure the water-cooled heat dissipation and cooling effect of the enamel tube 9.

[0032] The above-mentioned outer shell 1 is connected to low voltage as an outer electrode, and the enamel tube 9 is connected to high voltage as an inner electrode. The outer shell 1 is preferably made of stainless steel. Preferably, the outer wall of the enamel tube 9 is provided with a plurality of convex points 15 at intervals, and the outer wall of the enamel tube 9 is fixedly connected to the inner wall of the outer shell 1 through the convex points 15. Further, the outer wall of the enamel tube 9 is distributed with convex points 15 near its upper and lower ends. Specifically, the outer wall of the enamel tube 9 is distributed with four convex points 15 near its upper and lower ends, and the four convex points 15 above and below are evenly distributed on the outer wall of the enamel tube 9. In addition, more convex points 15 can be distributed; the present invention forms a plurality of fixed channels, i.e., gas path channels, in the discharge chamber by providing a plurality of convex points 15, and ozone is generated and discharged from the gas path channels. The convex points 15 can play a positioning role to evenly control the discharge gap, thereby making the discharge uniform, the generation of ozone more uniform, the ozone concentration higher, and not easy to burn or explode porcelain.

[0033] Preferably, the lower end surface (ie, the inner end surface or the rear end surface) of the sealing cover 2 is provided with a gas storage groove 4 connected to the ozone outlet 3 , and the ozone outlet 3 can be specifically located at the bottom wall or side wall of the gas storage groove 4 .

[0034] Specifically, the upper end surface (i.e., the outer end surface or the front end surface) of the sealing cover 2 is provided with an ozone exhaust valve 5 connected to the ozone exhaust port 3. The ozone exhaust valve 5 is connected to an external ozone tube 8, so that the ozone in the discharge chamber is discharged to the outside through the ozone exhaust port 3, the ozone exhaust valve 5, and the ozone tube 8.

[0035] Preferably, the ozone discharge valve 5 is in a tower shape with a small outer diameter at the top and a large outer diameter at the bottom. The lower part of the ozone discharge valve 5 is provided with threads for threaded connection with the ozone tube 8. By setting the ozone discharge valve 5 with a small upper and a large lower tower shape, the ozone tube 8 is less likely to fall off under the double force of the lower thread and the extrusion, thereby improving the connection stability between the ozone discharge valve 5 and the ozone tube 8. In addition, the ozone discharge valve 5 with a small upper and a large lower tower shape also has the following beneficial effects: the upper discharge port of the ozone discharge valve 5 is small and the internal space is large, forming a high pressure, so that the ozone discharge valve 5 can discharge ozone with a higher concentration, continuously and stably. Preferably, the ozone discharge valve 5 and the sealing cover 2 are integrally formed.

[0036] In addition, a through hole 6 may be provided in the middle of the sealing cover 2, and the through hole 6 passes through the upper and lower end surfaces of the sealing cover 2. The end of the enamel tube 9 passes through the through hole 6, so that the end of the enamel tube 9 can be connected to a high-voltage lead (as a high-voltage end), or the second water inlet 13 and the second water outlet 14 can be connected to a cooling water pipe. It can be understood that the high-voltage lead is used to apply high pressure to the enamel tube 9.

[0037] Specifically, the sealing cover 2 is made of insulating material. Preferably, an insulating cap 7 is provided on the upper end surface of the sealing cover 2. It can be understood that the end of the above-mentioned outer shell 1 is provided with a low-voltage end bolt and a low-voltage end nut 16 as a low-voltage lead for connecting the low-voltage end, wherein the upper end of the low-voltage end bolt is exposed from the upper end surface of the sealing cover 2, and the above-mentioned insulating cap 7 is used to wrap the upper end of the low-voltage end bolt. During the ozone generation process, there is a high voltage of several thousand volts. If the high-voltage end and the low-voltage end are not isolated, it is easy to generate an arc between the high-voltage end and the low-voltage end, which can easily lead to problems such as fire, burning, and short circuit; in addition, when the cooling water temperature is too low, due to the relatively high internal heat and the large temperature difference with the outside, condensation will occur on the surface of the outer shell 1, the sealing cover 2, etc., and condensation on the surface is easy to conduct electricity, which can easily lead to arcing and sparking between the high-voltage end and the low-voltage end; therefore, the present invention isolates the high-voltage end from the low-voltage end through the above-mentioned insulating cap 7 to avoid high-voltage and low-voltage contact, thereby better avoiding the above-mentioned problems such as fire, burning, and short circuit, and better ensuring the safety of the use of the enamel ozone generator. The insulating cap 7 is preferably formed integrally with the sealing cover 2; the number of the insulating caps 7 can be eight or the like, and no excessive restrictions are imposed herein.

[0038] In addition, preferably, a silicone gasket is installed between the sealing cover 2 and the enamel tube 9; the outer shell 1 can be connected to two tripods 17.

[0039] Compared with the prior art, the present invention provides a double water-cooled enamel ozone generator, which has the following beneficial effects: (1) The tube wall of the outer shell of the present invention is a double-layer structure, a cavity is formed inside the tube wall of the double-layer structure, a first water inlet and a first water outlet connected to the cavity are arranged on the outer shell, and a second water inlet and a second water outlet are arranged at both ends of the enamel tube, and the interior of the enamel tube is connected to the second water inlet and the second water outlet. Through the above manner, the present invention adopts a double water-cooling structure to cool and dissipate the heat of the enamel ozone generator, which can better ensure the cooling effect of the enamel ozone generator, so as to better discharge the heat in the enamel ozone generator, so that the generated ozone is not easy to decompose and avoid affecting the concentration of ozone; (2) The convex points on the outer wall of the enamel tube can play a positioning role to uniformly control the discharge gap, so that the discharge is uniform, the generation of ozone is more uniform, the ozone concentration is higher, and it is not easy to burn or explode porcelain; (3) The first water inlet is close to the lower end of the outer shell. The first water outlet is arranged near the upper end of the outer shell, the second water inlet is arranged at the lower end of the enamel tube, and the second water outlet is arranged at the upper end of the enamel tube, which can maximize the guarantee that the cavity of the outer shell and the interior of the enamel tube are filled with cooling water to ensure the water-cooled heat dissipation and cooling effect; (4) The lower end surface of the sealing cover is provided with a gas storage groove connected to the ozone discharge port. The gas storage groove can be used to store ozone and buffer pressure as a reflux storage space for ozone in the discharge chamber, so that the sealing cover can play a certain reflux storage role for ozone. After the reflux storage space is filled with ozone, it is discharged outward through the ozone discharge port. Compared with the prior art sealing cover with a flat lower end surface, the present invention can better make the ozone discharge flow more stable, that is, better achieve the discharge of more stable and higher concentration ozone; (5) The insulating cap can isolate the high-voltage end from the low-voltage end to avoid high-voltage and low-voltage contact, thereby better avoiding problems such as fire, burning, and short circuit, and better ensuring the safety of the use of the ozone generator.
