Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device containing ozone. Background Art

[0002] At present, waste gas purification mainly refers to the treatment of industrial waste gas such as dust particles, flue gas, odorous gas, and toxic and harmful gas generated in industrial places. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc.; Regarding ozone, it is an oxygen allotrope composed of three oxygen atoms. It is usually a light blue gas, which can become a dark brown liquid under high pressure. Under standard conditions, the density is 2.144g / L, and the decomposition rate of ozone in the air increases with increasing temperature. The half-life of ozone with a concentration of less than 1% at room temperature and pressure is about 16h, so ozone is not easy to store and needs to be used while being produced. The decomposition rate of ozone in pure water is much faster than that in air. When the ozone concentration in water is 3mg / L, the half-life at room temperature and pressure is only 5~30min.

DETAILED DESCRIPTION

[0017] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-7As shown, an ozone-containing waste gas treatment device comprises a bottom plate 1, a high-pressure air pump 2 is fixedly installed on the upper surface of the bottom plate 1 near the front side, a decomposition cylinder 3 is fixedly installed in the middle part of the upper surface of the bottom plate 1, and a sealing cover 4 is fixedly connected to the top of the decomposition cylinder 3. Before use, the decomposition cylinder 3 is filled with decomposition water and covered with the sealing cover 4 to prevent waste gas leakage when the equipment is used, because ozone also has a strong corrosive effect on non-metallic materials. Therefore, ordinary rubber cannot be used as a sealing material, and silicone rubber or acid-resistant rubber with strong corrosion resistance should be used for sealing treatment to achieve a long-term sealing effect. The air outlet of the high-pressure air pump 2 is fixedly connected to one end of the air inlet pipe 5, and the other end of the air inlet pipe 5 passes through the side wall of the decomposition cylinder 3 and extends vertically to the bottom of the inner surface near the decomposition cylinder 3, so that the exhaust gas floats upward from the bottom of the water, so that the reaction effect of ozone and decomposition water is maximized. At the same time, the air inlet pipe 5 passes through the decomposition cylinder 3 near the top and extends downward to prevent the decomposition water from flowing back from the air inlet pipe 5 to the high-pressure air pump 2 and flowing out when the high-pressure air pump 2 is not started. A heating pipe 10 is fixedly installed near the edge of the inner surface of the decomposition cylinder 3, and the heating pipe 10 heats the decomposition water before the exhaust gas enters to increase its temperature. A control panel 6 is fixedly installed on the outer surface of the decomposition cylinder 3. The control panel 6 is used to control the switches of other electrical equipment in the high-pressure air pump 2, the motor 11 and other devices, as well as the temperature increase of the heating pipe 10, so as to prevent the heating pipe 10 from directly boiling the decomposition water. The decomposition cylinder 3 is away from the air inlet. One side of the tube 5 is fixedly connected near the top and is internally connected with one end of an air outlet pipe 7, and the other end of the air outlet pipe 7 is fixedly connected to the air inlet side of the activated carbon adsorption box 8. The air outlet pipe 7 is opened above the horizontal plane filled with decomposition water to prevent water from flowing into the activated carbon adsorption box 8 from the air outlet pipe 7. The door of the activated carbon adsorption box 8 faces outward, which is convenient for replacing the activated carbon in the activated carbon adsorption box 8 at a later time. The air outlet side of the activated carbon adsorption box 8 is fixedly connected with an air outlet pipe 29, and the external gas is drawn into the activated carbon adsorption box 8 by starting the high-pressure air pump 2. The high-pressure air pump 2 is discharged from the air inlet pipe 15 to the inside of the decomposition cylinder 3. At this time, the decomposition water is heated by the heating pipe 10, and the waste gas containing ozone will be discharged from the water. The high temperature accelerates the molecular movement, so that the ozone in the waste gas is quickly decomposed while the water is discharged and rising, and then discharged from the air outlet pipe 17 to the activated carbon adsorption box 8 to adsorb other waste gas molecules, and the purpose of waste gas purification has been achieved. Compared with the waste gas treatment device containing ozone on the market, this device can achieve the same waste gas treatment effect while being smaller in size, and the corresponding cost is also reduced. In actual use, the top of the outlet pipe 29 should be facing downward or a structure such as a ceiling should be installed on its top to prevent rainwater from pouring into the inside of the outlet pipe 29 when used outdoors and flowing into the activated carbon adsorption box 8 along the pipe wall, thereby affecting the normal use of the activated carbon adsorption box 8.

[0019] like Figure 1 , 3As shown, in some embodiments, a motor 11 is fixedly installed at the top center of the sealing cover 4, and a main shaft 12 is fixedly connected to the bottom output end of the motor 11. The main shaft 12 penetrates the sealing cover 4 and extends to the inside of the decomposition tube 3. The outer surface of the main shaft 12 is located inside the decomposition tube 3 and a stirring rod 13 is installed. Specifically, after starting the motor 11, its output end drives the main shaft 12 and the stirring rod 13 to rotate, thereby driving the decomposition water in the decomposition tube 3 to stir, so that the exhaust gas discharged into the decomposition tube 3 can be fully mixed with the decomposition water, and the ozone in the exhaust gas is prevented from reacting only with the decomposition water in the surrounding area. In actual use, the extension length of the stirring rod 13 is short to avoid being blocked by the heating tube 10 and the air inlet pipe 5 during stirring. The stirring rod 13 drives the decomposition water to rotate at a uniform speed.

[0020] like Figure 1 As shown, in some embodiments, an air pressure detector 14 is fixedly installed on the outer surface of the decomposition cylinder 3, and the detection head of the air pressure detector 14 passes through the side wall of the decomposition cylinder 3 and extends to the interior of the decomposition cylinder 3. The air pressure detector 14 is electrically connected to the control panel 6. Specifically, the air pressure inside the decomposition cylinder 3 is detected in real time by the installed air pressure detector 14. When the detected air pressure becomes slightly higher, the efficiency of the high-pressure air pump 2 should be controlled through the control panel 6 to avoid the exhaust gas drawn in by the high-pressure air pump 2 from being discharged faster after heating, which will affect the adsorption effect of the activated carbon.

[0021] like Figure 2 , 5 As shown, in some embodiments, the decomposition cylinder 3 is fixedly connected to an extension plate 15 on the side surface away from the air inlet pipe 5, and a support rod 16 is fixedly connected to the upper surface of the extension plate 15. A small wind turbine 17 is fixedly installed on the top of the support rod 16. The outer surface of the blade part of the small wind turbine 17 is sleeved with a connecting cover 18, and the connecting cover 18 is located between the air outlet pipe 7 and the activated carbon adsorption box 8. The air outlet pipe 7 is fixedly connected to one side of the connecting cover 18 near the top. The connecting cover 18 is located on the opposite side of the small wind turbine 17 and is fixedly connected and internally connected to the air inlet side of the activated carbon adsorption box 8. The upper surface of the bottom plate 1 is fixed below the extension plate 15. A backup battery 19 is installed, and the backup battery 19 is electrically connected to the small wind turbine 17. Specifically, the exhaust gas is connected through an exhaust pipe 7 and blown into a connecting cover 18, so that the exhaust gas simultaneously blows the fan blades of the small wind turbine 17, thereby recovering a portion of the electricity while treating the exhaust gas and storing it in the backup battery 19. At the same time, the control panel 6 can be used to switch the power supply between the external connection and the backup battery 19. When it is detected that the power in the backup battery 19 is full, it switches to the backup battery 19 for power supply until the power is consumed, and then switches to the external power supply for power supply, so as to avoid overflow of the backup battery 19 after it is fully charged, so as to achieve the purpose of maximizing power saving.

[0022] like Figure 5As shown, in some embodiments, the fan blades of the small wind turbine 17 are set to U-shaped fan blades 23, and the concave surface of the U-shaped fan blades 23 faces the air outlet of the air outlet pipe 7. Specifically, the installed U-shaped fan blades 23 improve the effect of the small wind turbine 17 in catching wind, so that the same wind force can drive the U-shaped fan blades 23 to rotate faster and make fuller use of the wind force, thereby improving the power generation effect of the small wind turbine 17.

[0023] like Figure 4 As shown, in some embodiments, a fixed block 20 is fixedly connected to the bottom of the inner surface of the decomposition cylinder 3 near the edge, a ventilation groove 21 is opened inward at the top of the fixed block 20, the top of the fixed block 20 is fixedly connected and internally connected to the other end of the air inlet pipe 5, the bottom end of the ventilation groove 21 is located in the internal circular array of the fixed block 20 and is opened with a plurality of diversion grooves 22. Specifically, the waste gas entering the decomposition cylinder 3 is divided into more and smaller bubbles through the opened diversion grooves 22, thereby increasing the contact area between the ozone in the waste gas and the decomposition water, improving the reaction effect of the ozone, and further reducing the concentration of the ozone after discharge.

[0024] like Figure 1 , 7 As shown, in some embodiments, the outer surface of the decomposition cylinder 3 is fixedly connected near the bottom and internally connected with a drain pipe 32, and a valve 33 is fixedly installed in the middle part of the drain pipe 32. Specifically, the decomposition water can be quickly discharged after use through the installed drain pipe 32, and the valve 33 is used to control the switch of the drain pipe 32. When using the device, the valve 33 is tightened to prevent the decomposition water from leaking. After a certain period of use, the valve 33 is unscrewed to discharge the sewage from the drain pipe 32. In actual use, the end of the drain pipe 32 can be set to a threaded shape, and then the drain pipe 32 can be connected to other pipes to make the wastewater flow to a designated location or container for subsequent treatment.

[0025] like Figure 6 As shown, in some embodiments, the upper surface of the base plate 1 is located on the opposite side of the high-pressure air pump 2 and is fixedly connected with three support columns 25, the top of the support column 25 is fixedly connected with a connecting tube 26, and a vent hole 27 is opened at the bottom center of the connecting tube 26, the air inlet of the high-pressure air pump 2 is fixedly connected with one end of the air inlet pipe 24, the other end of the air inlet pipe 24 is fixedly connected and internally connected with the vent hole 27, a filter cartridge 28 is placed inside the connecting tube 26, and one side of the filter cartridge 28 is fixedly connected and internally connected with a connecting pipe 29. Specifically, the waste gas before treatment is dust filtered by the filter cartridge 28 in the connecting tube 26 to prevent the decomposition water from being contaminated by the residue and dust in the waste gas too quickly and becoming unusable. The connecting pipe 29 is used to connect the exhaust pipe of other equipment. In actual use, the filter cartridge 28 can be rotated so that the side away from the connecting pipe 29 is rotated to the side of the connecting pipe 29, so that one filter cartridge 28 can be fully utilized and then replaced.

[0026] like Figure 6 As shown, in some embodiments, a top cover 30 is placed on the top of the connecting tube 26, and a handle 31 is fixedly installed on the upper surface of the top cover 30. Specifically, by using the top cover 30 to seal the top, the top cover 30 can be directly opened to replace the filter cartridge 28 after long-term use, which is convenient and quick to operate. In actual use, the inner ring of the top cover 30 should be treated with acid-resistant rubber and other structures like the sealing cover 4.

[0027] like Figure 3 As shown, in some embodiments, four universal wheels 34 are fixedly installed near the edge of the outer surface of the bottom plate 1. Specifically, the universal wheels 34 are used to support the device so that the device can be moved on flat ground, thereby facilitating the direct pushing of the device to move on narrow roads. In actual use, the universal wheels 34 are universal wheels 34 with brake clamping structures installed, which facilitates the position of the device after moving and prevents it from being displaced.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
