Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to an ozone catalytic oxidation tower. Background Art

[0002] Ozone is an allotrope of oxygen with strong oxidizing properties. It can be used as a bleaching agent, deodorizing agent, air purifier and disinfectant. When ozone is used as a wastewater treatment agent, it can oxidize and decompose various organic and inorganic substances in the wastewater or destroy their structures, reduce the concentration of pollutants in the wastewater, and ozone treatment has the characteristics of rapid reaction. Ultraviolet light (UV) excitation is often used when ozone is used to treat wastewater. Under the excitation of ultraviolet light, ozone can generate OH free radicals. Hydroxyl free radicals have strong oxidizing properties and can degrade pollutants and improve the efficiency of ozone treatment. Ozone catalytic oxidation tower is a common equipment for wastewater ozone treatment. A certain number of ultraviolet lamps are set in the tower as excitation light sources. The direction of the lamps is the same as the flow direction of the wastewater. When ozone passes through the ultraviolet lamps, hydroxyl free radicals are generated under the excitation of ultraviolet rays. Hydroxyl free radicals quickly react with pollutants in the wastewater, such as the catalytic oxidation reaction device disclosed in CN218465640U. Normally, UV lamps are only installed on a certain layer of the ozone oxidation tower, and the entire tower space will not be covered with UV lamps, which will greatly increase equipment costs and power consumption. Ozone is generally introduced from the bottom of the tower, and unreacted and generated waste gas is discharged from the top of the tower. The problem with this arrangement is that the contact time between ozone and UV lamps is short, and some ozone leaves the photocatalytic layer without being excited. The ozone excitation efficiency is low, which reduces the ozone treatment effect. Utility Model Content

[0003] The utility model solves the problem of low excitation efficiency of ozone when it flows through an ultraviolet lamp irradiation layer and provides an ozone catalytic oxidation tower in which ultraviolet lamp tubes are arranged in layers to improve ozone excitation efficiency.

[0004] In order to solve the above technical problems, the utility model comprises a tower body with a top seal, the upper part of the tower body is a water inlet area for wastewater to enter, the bottom of the tower body is a water outlet area for wastewater to be discharged, an ultraviolet irradiation area for exciting ozone is arranged in the tower body, the ultraviolet irradiation area is located between the water inlet area and the water outlet area, the water outlet area is connected to an ozone generator through a pipeline, an exhaust port is arranged on the top of the tower body, and its structural characteristics are: the ultraviolet irradiation area comprises an upper ultraviolet irradiation area and a lower ultraviolet irradiation area arranged up and down, the upper ultraviolet irradiation area is located below the water inlet area, the lower ultraviolet irradiation area is located above the water outlet area, a middle ozone inlet area for ozone to enter is located between the upper ultraviolet irradiation area and the lower ultraviolet irradiation area, the ozone generator is connected to the middle ozone inlet area through a pipeline, the upper ultraviolet irradiation area and the lower ultraviolet irradiation area are both provided with a plurality of ultraviolet lamp tubes, and the length direction of the ultraviolet lamp tubes is the same as the flow direction of wastewater.

[0005] After adopting the above structure, wastewater enters from the water inlet area at the upper part of the tower body, flows downward after entering the tower body, and ozone enters from the water outlet area at the bottom of the tower body and the middle ozone air inlet area between the upper ultraviolet irradiation area and the lower ultraviolet irradiation area. After entering the tower body, it flows upward. When the ozone passes through the upper ultraviolet irradiation area and the lower ultraviolet irradiation area, part of the ozone generates hydroxyl free radicals under the excitation of ultraviolet rays emitted by the ultraviolet lamp tube. The hydroxyl free radical has strong oxidizing property and can react quickly with pollutants in the wastewater, thereby removing the pollutants. The wastewater treated with ozone is discharged from the water outlet area at the bottom of the tower body, and the unreacted ozone and the generated waste gas are discharged through the exhaust port at the top of the tower body. The tower body of the ozone catalytic oxidation tower of the utility model is provided with upper and lower layers of ultraviolet irradiation zones, and multiple ultraviolet lamps are arranged in the two layers of ultraviolet irradiation zones. Under the condition that the total number of ultraviolet lamps, the total radiation intensity and the amount of ozone introduced are the same, if only one layer of ultraviolet irradiation zone is provided, although the ultraviolet radiation intensity is stronger and the ozone concentration is higher, the residence time of ozone in the ultraviolet irradiation zone is shorter. The present application sets two layers of ultraviolet irradiation zones, and although the ultraviolet radiation intensity of the single layer of ultraviolet irradiation zone is lower than that of only one layer of ultraviolet irradiation zone, the residence time of ozone in the ultraviolet irradiation zone is shorter. The residence time in the irradiation zone is longer, and the excitation time by ultraviolet rays is prolonged, which can improve the total excitation efficiency of ozone; ozone is introduced from two points corresponding to the two layers of ultraviolet irradiation zones, a part of ozone enters from the water outlet area below the lower ultraviolet irradiation zone, and the other part of ozone enters from between the two layers of ultraviolet irradiation zones, so that there is a certain concentration of ozone when passing through the two layers of ultraviolet irradiation zones, avoiding the ozone concentration in one layer of ultraviolet irradiation zone being too high or too low, resulting in a large difference between the ozone excitation efficiency and the hydroxyl free radicals generated by the excitation in the two layers of ultraviolet irradiation zones. Compared with the ozone catalytic oxidation tower with only one layer of ultraviolet lamp tubes, the utility model improves the excitation efficiency of ozone by setting two layers of ultraviolet irradiation zones and two points of ozone introduction, produces more hydroxyl free radicals, and thus improves the ozone treatment effect of wastewater.

[0006] The number of ultraviolet lamps in the upper ultraviolet irradiation zone is greater than the number of ultraviolet lamps in the lower ultraviolet irradiation zone.

[0007] Upper lamp tube supports for fixing the ends of the ultraviolet lamp tubes are respectively provided above and below the upper ultraviolet irradiation zone, and lower lamp tube supports for fixing the ends of the ultraviolet lamp tubes are respectively provided above and below the lower ultraviolet irradiation zone. Both the upper lamp tube supports and the lower lamp tube supports are in the shape of long strips.

[0008] The ozone generator is connected to the middle ozone air inlet area and the water outlet area respectively through two ozone branch pipes, and the two ozone branch pipes are both provided with regulating valves for controlling the ozone flow rate.

[0009] The middle ozone air inlet area and the water outlet area are both provided with ozone distribution pipes for ozone transportation, and the ozone distribution pipes are connected with a plurality of aeration plates for uniformly releasing ozone.

[0010] The side walls of the tower body are provided with sight glasses respectively located in the upper ultraviolet irradiation area and the lower ultraviolet irradiation area for observing the ultraviolet lamp tube.

[0011] The water inlet area is provided with a liquid level meter for controlling the liquid level height in the tower.

[0012] The utility model provides an ozone catalytic oxidation tower with an upper ultraviolet irradiation zone and a lower ultraviolet irradiation zone, which increases the contact time between ozone and ultraviolet lamps. Ozone is introduced below both the upper ultraviolet irradiation zone and the lower ultraviolet irradiation zone, and the total excitation efficiency of ozone and the generation amount of hydroxyl free radicals are increased by increasing the time for ozone to be excited by ultraviolet rays and adjusting the ozone amount of two ozone branch pipes, thereby improving the ozone treatment effect of wastewater. Wastewater flows from top to bottom in the tower, and the pollutant concentration in the wastewater flowing through the upper ultraviolet irradiation zone is relatively high, so more ultraviolet lamps are arranged in the upper ultraviolet irradiation zone, and relatively more hydroxyl free radicals are generated in the upper ultraviolet irradiation zone and relatively fewer hydroxyl free radicals are generated in the lower ultraviolet irradiation zone by adjusting the ozone flow rate of the two ozone branch pipes, so that the generation amount of hydroxyl free radicals in space is adapted to the pollutant concentration in the wastewater.

An exhaust port 14 is provided on the seal at the top of the tower body. A plurality of ultraviolet lamp tubes 6 are provided in both the upper ultraviolet irradiation area 2 and the lower ultraviolet irradiation area 4. The length direction of the ultraviolet lamp tubes 6 is the same as the flow direction of the wastewater in the tower. Figure 1 As shown, the ultraviolet lamp 6 is installed in a vertical direction, and the middle ozone inlet area 3 and the water outlet area 5 are connected to the ozone generator 8 through pipelines. Figure 1 , 6 As shown, a water inlet 11 is provided on the side wall of the tower body of the water inlet area 1, and a water distribution pipe 12 connected to the water inlet 11 is provided inside the water inlet area 1. Figure 6 As shown, the water distribution pipe 12 is closed, and a plurality of water distribution holes 121 are provided on the water distribution pipe 12. After the wastewater flows out through the water distribution holes 121, it enters the tower body, and the water distribution pipe 12 plays the role of uniform water distribution. The water inlet area 1 is also provided with a liquid level meter 13 for controlling the liquid level height in the tower. The inlet flow rate or discharge flow rate of the wastewater is controlled according to the liquid level height in the tower detected by the liquid level meter 13, so that the liquid level in the tower is controlled in a suitable range. The liquid level meter 13 can be in the form of a magnetic flap or a liquid level float; a water inlet area manhole 15 is also provided on the side wall of the tower body of the water inlet area 1.

[0021] Reference Figure 1 , 4 5, upper lamp tube supports 21 are provided above and below the upper ultraviolet irradiation area 2 for fixing and supporting the ends of the ultraviolet lamp tube 6, such as Figure 1As shown, the upper end of the ultraviolet lamp tube 6 of the upper ultraviolet irradiation zone 2 is fixed to the upper lamp tube bracket 21 above, and the lower end of the ultraviolet lamp tube 6 is fixed to the upper lamp tube bracket 21 below, as shown in FIG. Figure 5 As shown, the upper lamp bracket 21 includes twelve long strip brackets radiating outward from the center of the tower body. The twelve brackets are evenly distributed according to the circumferential angle with the center of the tower body as the center. Two or three ultraviolet lamps 6 are fixedly installed on each bracket. The brackets for installing two or three ultraviolet lamps 6 are arranged at intervals. Of course, the number of upper lamp brackets 21 and ultraviolet lamps 6 can also be designed to be other values; the tower side wall of the upper ultraviolet irradiation area 2 is also provided with an upper ultraviolet area manhole 23 and an upper mirror 22 for observing the operation of the internal ultraviolet lamp 6.

Figure 4 , 5 It can be seen that the number of ultraviolet lamps 6 in the upper ultraviolet irradiation zone 2 is greater than the number of ultraviolet lamps 6 in the lower ultraviolet irradiation zone 4. Because the wastewater flows from top to bottom, the pollutant concentration of the wastewater is higher when it flows through the upper ultraviolet irradiation zone 2. Therefore, the number of ultraviolet lamps 6 in the upper ultraviolet irradiation zone 2 is designed to be larger, and the ultraviolet radiation is stronger, so that the upper ultraviolet irradiation zone 2 produces more hydroxyl free radicals, which matches the pollutant concentration in the wastewater; the upper lamp tube bracket 21 and the lower lamp tube bracket 41 can be made of stainless steel angle steel and other profiles. The upper lamp tube bracket 21 and the lower lamp tube bracket 41 can also adopt other layout forms, such as a plurality of parallel long strip brackets that are criss-crossed to form a grid.

The aeration plates 7 adopt microporous aeration. After the ozone passes through the aeration plates 7, countless tiny bubbles are formed and emitted into the tower body, so that the ozone is evenly distributed in the wastewater in the form of tiny bubbles, which is conducive to the ozone being excited by the ultraviolet lamp 6; a middle ozone air distribution pipe 32 connected to the middle ozone inlet 31 is arranged in the middle ozone air inlet area 3, and a plurality of aeration plates 7 are arranged on the middle ozone air distribution pipe 32. The structural form of the middle ozone air distribution pipe 32 and the aeration plates 7 connected thereto are the same as those of the bottom ozone air distribution pipe 52, which are not shown in the figure; as shown in the figure Figure 2 , 3 As shown, a manhole 56 for the water outlet area is provided on the side wall of the tower body of the water outlet area 5, and a manhole is also provided on the side wall of the tower body of the middle ozone inlet area 3, which is not shown in the figure. The middle ozone inlet 31 and the bottom ozone inlet 51 are both connected to the ozone generator 8 through pipelines. Specifically, the middle ozone inlet 31 is connected to the ozone generator 8 through a first ozone branch pipe 81, and the bottom ozone inlet 51 is connected to the ozone generator 8 through a second ozone branch pipe 82. The first ozone branch pipe 81 is provided with a first regulating valve 811, and the second ozone branch pipe 82 is provided with a second regulating valve 821. The ozone flow in the branch pipe is adjusted by the first regulating valve 811 and the second regulating valve 821, thereby controlling the flow of ozone from the bottom and the middle into the tower body. A water collecting pipe 54 connected to the water outlet 53 is provided in the water outlet area 5. The water collecting pipe 54 is closed and has a plurality of drainage holes 541.

When the wastewater in the tower needs to be emptied, it is discharged from the drain port 55. The tower body and internal components of the ozone catalytic oxidation tower are made of materials resistant to corrosion by ozone and wastewater.

[0023] Working process: turn on the ultraviolet lamps 6 of the upper ultraviolet irradiation zone 2 and the lower ultraviolet irradiation zone 4, the wastewater enters the water inlet zone 1 and flows out from the water distribution holes 121 on the water distribution pipe 12, the wastewater enters the inside of the ozone catalytic oxidation tower and flows downward, the ozone enters the tower from the bottom ozone air distribution pipe 52 and the aeration plate 7 on the middle ozone air distribution pipe 32, the ozone flows upward after entering the catalytic oxidation tower, the wastewater and ozone are in countercurrent contact in the tower, the oxidizing property of the ozone itself can oxidize and decompose some pollutants in the wastewater, when the ozone flows through the upper ultraviolet irradiation zone 2 and the lower ultraviolet irradiation zone 4, hydroxyl radicals are generated under the excitation of the ultraviolet light emitted by the ultraviolet lamp 6, the hydroxyl radicals have strong oxidizing properties, can quickly react with the pollutants in the wastewater and decompose and remove the pollutants, the wastewater treated with ozone enters the water collecting pipe 54 through the drainage hole 541, and is finally discharged from the water outlet 53; the unreacted ozone and the generated waste gas are discharged centrally through the exhaust port 14 at the top of the tower. The ozone catalytic oxidation tower of the utility model is provided with an upper ultraviolet irradiation zone 2 and a lower ultraviolet irradiation zone 4, which have two layers of ultraviolet irradiation zones in total. A middle ozone air distribution pipe 32 is provided below the upper ultraviolet irradiation zone 2, and a bottom ozone air distribution pipe 52 is provided below the lower ultraviolet irradiation zone 4. Under the condition that the total number of ultraviolet lamps 6 and the amount of ozone introduced are constant, compared with only one layer of ultraviolet irradiation zone, the two layers of ozone irradiation zones increase the space of the ultraviolet irradiation zone. The unreacted ozone after passing through the lower ultraviolet irradiation zone 4 is excited by ultraviolet light again when passing through the upper ultraviolet irradiation zone 2, which increases the contact time between ozone and the ultraviolet lamp 6 as a whole, is beneficial to improving the total excitation efficiency of ozone, and generates more hydroxyl free radicals. The ultraviolet in the upper ultraviolet irradiation zone 2 The number of lamp tubes 6 is greater than the number of ultraviolet lamp tubes 6 in the lower ultraviolet irradiation zone 4. When the wastewater passes through the upper ultraviolet irradiation zone 2, the pollutant concentration in the wastewater is higher. Therefore, more ultraviolet lamp tubes 6 are set in the upper ultraviolet irradiation zone 2. The ultraviolet radiation intensity of the upper ultraviolet irradiation zone 2 is higher. At the same time, the first regulating valve 811 and the second regulating valve 821 are adjusted to make the ozone concentration in the upper ultraviolet irradiation zone 2 and the lower ultraviolet irradiation zone 4 adapt to the ultraviolet radiation intensity and the concentration of wastewater pollutants, so as to avoid the ozone excitation efficiency and hydroxyl radical generation of the upper ultraviolet irradiation zone 2 and the lower ultraviolet irradiation zone 4. The ozone flow of the first ozone branch pipe 81 and the second ozone branch pipe 82 is generally determined by debugging during wastewater treatment to achieve the best treatment effect. The utility model sets two layers of ultraviolet irradiation zones. On the basis of a certain number of ultraviolet lamp tubes 6, if too many layers of ultraviolet irradiation zones are set, the number of single-layer ultraviolet lamp tubes 6 is small, the ultraviolet intensity is low, the ozone excitation effect is reduced, and the installation difficulty and equipment cost are increased.

[0024] The utility model provides an ozone catalytic oxidation tower with upper and lower ultraviolet irradiation zones, each of which is provided with a plurality of ultraviolet lamp tubes, thereby increasing the space of the ultraviolet irradiation zones and the excitation time of ozone by the ultraviolet lamp tubes, and improving the total excitation efficiency of ozone; the number of ultraviolet lamp tubes in the upper ultraviolet irradiation zone is greater than that in the lower ultraviolet irradiation zone, an ozone air distribution pipe is provided below each ultraviolet irradiation zone, and the ozone flow rate of the ozone air distribution pipe is adjustable, so that the ultraviolet radiation intensity and ozone concentration of the upper and lower ultraviolet irradiation zones are matched with the pollutant concentration in the wastewater, and the ozone treatment effect is improved.
