Description

Technical Field

[0001] The invention belongs to the technical field of sewage and wastewater treatment, and in particular relates to an ozone catalytic oxidation tower reaction device. Background Art

[0002] Ozone is a strong oxidant that can be used to treat large molecular and polycyclic benzene pollutants, as well as oils, chlorinated solvents and other trace organic pollutants. Ozone catalytic oxidation technology is a type of ozone advanced oxidation technology. It mainly uses various catalytic means to allow sufficient physical and chemical reactions to occur between ozone and the catalyst, stimulating it to produce free radicals with extremely strong oxidizing ability (hydroxyl radicals and superoxide radicals, etc.), thereby oxidizing and decomposing difficult-to-degrade pollutants in wastewater.

[0003] An ozone catalytic oxidation tower is a device that uses ozone to treat wastewater. After long-term use, the surface of the catalyst in the ozone catalytic oxidation tower will be covered with pollutants or undergo chemical changes, resulting in a reduction in active sites, thereby reducing the catalytic efficiency. Therefore, the catalyst needs to be cleaned and regenerated regularly, but the concentration of wastewater and the treatment rate of wastewater are not fixed. A larger wastewater concentration and a faster treatment rate will cause the catalyst to react strongly with a large amount of pollutants, accelerating its loss. Therefore, a fixed treatment frequency of the catalyst cannot replenish the loss of the catalyst in time, affecting the treatment quality of the wastewater. In order to improve the treatment efficiency of wastewater, the introduction speed of wastewater is generally set high. However, for wastewater with a high degree of pollution, more sufficient reaction time is required to decompose pollutants. An introduction rate that is too fast cannot achieve the expected treatment goal, affecting the treatment quality of wastewater, and failing to achieve an optimal balance between the treatment quality and treatment efficiency of wastewater.

[0024] The bottom ends of the water inlet pump 9 and the ozone generator 11 are fixedly provided with a supporting bottom plate, and the wastewater concentration feedback control mechanism 2, the catalyst treatment prompt mechanism 3, the ozone generation rate control mechanism 4 and the water inlet rate control mechanism 5 are all fixedly provided on the supporting bottom plate.

[0025] The operating principle of the present invention is described as follows: the water inlet pump 9 cooperates with the water inlet pipe 10 to deliver the wastewater into the tower body 1, the ozone generator 11 cooperates with the air inlet pipe 12 to deliver the ozone gas into the tower body 1, and the pollutants in the wastewater are decomposed and treated by using ozone molecules; The concentration of pollutants in the sewage is measured in advance based on the existing sewage detection instrument, and the feedback motor 23 is started based on the final measured value. The feedback motor 23 drives the feedback screw 22 to rotate, and the feedback seat 24 drives the identification pointer 27 to move relative to the concentration scale plate 28 through the threaded sleeve effect of the feedback screw 22 and the feedback seat 24, until the indicated position of the identification pointer 27 on the concentration scale plate 28 is the same as the final measured value of the pollutant concentration. At this time, the feedback motor 23 is controlled to stop, and the feedback seat 24 drives the concentration feedback conductive contact 26 to slide relatively on the concentration feedback resistor rod 25 when moving. Specifically, the greater the pollutant concentration in the sewage, the greater the relative movement distance of the feedback seat 24, and thus the greater the sliding distance of the concentration feedback conductive contact 26 on the concentration feedback resistor rod 25, so that the access resistance value of the concentration feedback resistor rod 25 is smaller; The concentration feedback conductive contact 26 and the concentration feedback resistor rod 25 are connected in series to the power supply circuit of the thrust electromagnetic plate 64. When the thrust electromagnetic plate 64 is energized, it generates the same magnetism as the thrust permanent magnet plate 63, thereby driving the limiting plate 62 to move along the limit slide rod 61 to overcome the elastic force of the reset spring 65. Specifically, the greater the concentration of the sewage and wastewater, the smaller the access resistance of the concentration feedback resistor rod 25, thereby making the power supply current of the thrust electromagnetic plate 64 greater, making the magnetism of the thrust electromagnetic plate 64 stronger, and the distance that can push the limiting plate 62 to slide greater, thereby making the limit switch 66 closer to the extension plate 57; When treating wastewater, the regulating motor 53 is synchronously controlled to move, and the regulating motor 53 drives the regulating screw 52 to rotate. Through the threaded sleeve effect of the regulating screw 52 and the regulating seat 54, the regulating seat 54 drives the water inlet feedback conductive contact 56 to slide on the water inlet feedback resistor rod 55. The greater the moving distance of the regulating seat, the greater the sliding distance of the water inlet feedback conductive contact 56 on the water inlet feedback resistor rod 55, and the smaller the access resistance of the water inlet feedback resistor rod 55. In addition, the water inlet feedback conductive contact 56 and the water inlet feedback resistor rod 55 are connected in series with the water inlet feedback conductive contact 56. The power supply circuit of the pump 9, and the water inlet pump 9 is a DC pump. When the water inlet feedback resistor rod 55 is connected and the resistance value gradually decreases, the larger the power supply current of the water inlet pump 9, the power of the water inlet pump 9 is gradually increased, and the rate of sewage and waste water entry is accelerated until the extension plate 57 at the upper end of the adjustment seat 54 is pressed on the limit switch 66, at which time the adjustment motor 53 is stopped from continuing to operate, indicating that the water flow rate of the water inlet pump 9 has reached the maximum value. Specifically, the greater the concentration of the sewage and waste water, the smaller the distance that the adjustment seat 54 can move, and the smaller the sewage and waste water entry treatment rate; The concentration feedback conductive contact 26 and the concentration feedback resistor rod 25 are all connected in series with the water inlet feedback conductive contact 56 and the water inlet feedback resistor rod 55 in the power supply circuit of the force electromagnetic plate 45. When the pollution concentration of the sewage is higher, the resistance of the concentration feedback resistor rod 25 is smaller, thereby making the power supply current of the force electromagnetic plate 45 larger. The force electromagnetic plate 45 generates the same magnetism as the force permanent magnet plate 44 when it is energized, thereby making the ozone regulating plate 43 slide along the guide slide rod 42 to overcome the elastic force of the compensation spring 46. The pressing round head 48 at the lower end of the ozone regulating plate 43 can press on the power regulating switch 47 at the rear side. Similarly, when the connection resistance of the water inlet feedback resistor rod 55 is smaller, the water inlet speed is faster, and the power supply current of the force electromagnetic plate 45 is larger at this time. The pressing round head 48 can be pressed to trigger the power regulating switch 47 at the rear side. The power regulating switch 47 controls the working power of the ozone generator 11. The power regulating switch 47 at the rear side controls the ozone generator 11 to work at a greater power, so that the amount of ozone introduced is greater, and the amount of ozone introduced is automatically matched. It is also stated that when the tamping rod 410 is pressed on the in-place confirmation switch 49, it means that the amount of ozone generated by the ozone generator 11 has reached the maximum value. At this time, in the regulation of the sewage and wastewater introduction speed, even if the extension plate 57 is not pressed on the limit switch 66, the regulating motor 53 is immediately controlled to stop the action to avoid the problem that the sewage and wastewater introduction speed continues to increase without sufficient ozone to react with it, thereby affecting the sewage and wastewater treatment quality. In the process of treating the sewage, the driving motor 33 drives the reciprocating screw 32 to move synchronously. The threaded sleeve of the reciprocating screw 32 and the trigger plate 34 makes the trigger plate 34 move slowly in the prompt shell 31 until the trigger plate 34 presses on the trigger switch 35, indicating that the catalyst loss in the tower body 1 has reached the standard and the catalyst needs to be cleaned and regenerated. The trigger switch 35 controls the alarm 36 to sound, and promptly reminds the staff to perform corresponding treatment. The concentration feedback conductive contact 26 and the concentration feedback resistor rod 25 are all connected in series with the water inlet feedback conductive contact 56 and the water inlet feedback resistor rod 55 in the power supply circuit of the driving motor 33. The driving motor 33 is a DC motor. When the pollution concentration of the sewage is large and the sewage is introduced at a high rate, the access resistance values ​​of the concentration feedback resistor rod 25 and the water inlet feedback resistor rod 55 are respectively reduced, thereby accelerating the speed of the driving motor 33, making the interval time of the trigger plate 34 acting on the trigger switch 35 shorter, and more timely reminding the staff to perform corresponding regeneration treatment on the catalyst.
