Description

Technical Field

[0001] This utility model relates to the field of wastewater catalytic reaction technology, and in particular to a wastewater catalytic purification reaction tank. Background Technology

[0002] Ozone catalytic oxidation wastewater treatment equipment is a specialized device for treating pollutants in wastewater. Its core principle lies in utilizing the strong oxidizing properties of ozone, combined with the catalytic action of a catalyst, to oxidize and decompose organic matter, odors, and microbial pollutants in wastewater, transforming them into harmless products. This technology is widely used in wastewater purification to ensure that wastewater treatment meets standards.

[0003] A search revealed an ozone catalytic oxidation wastewater treatment device with publication number CN222729585U, comprising: an ozone catalytic oxidation wastewater treatment device body and a motor. The motor is fixedly connected to the top surface of a gear ring, and the output shaft of the motor passes through the top surface of the ozone catalytic oxidation wastewater treatment device body and extends into the body of the ozone catalytic oxidation wastewater treatment device body, rotatably connected to the ozone catalytic oxidation wastewater treatment device body. A rotating rod is fixedly connected to the output shaft of the motor, and a first broken blade is fixedly connected to the bottom end of the rotating rod. A rotating sleeve is disposed in the inner cavity of the ozone catalytic oxidation wastewater treatment device body and rotatably connected to the periphery of the rotating rod. This utility model solves the problem that when using an ozone catalytic oxidation reactor for high-efficiency wastewater treatment, the ozone and wastewater are simply stirred without dispersing the transported ozone, and the stirring method is relatively simple, making it impossible for ozone and wastewater to react quickly.

[0004] When the device in the disclosed patent is in use, ozone gas is directly discharged into the ozone catalytic oxidation wastewater treatment equipment through the gas supply pipe, which easily generates large bubbles and reduces the mixing effect of ozone gas and wastewater. Although some ozone bubbles can be broken up by stirring, it is difficult to guarantee the size of the bubbles when they float out of the wastewater. Moreover, the gas after floating out of the wastewater is directly discharged from the device, which easily leads to large ozone bubbles being directly discharged from the ozone catalytic oxidation wastewater treatment equipment, resulting in the waste of ozone gas. Utility Model Content

[0005] In response to existing patents, to address the technical problem that ozone gas is directly discharged into the ozone catalytic oxidation wastewater treatment equipment through a gas supply pipe during use, which easily generates large bubbles and reduces the mixing effect of ozone gas and wastewater, and although stirring can disperse some ozone bubbles, it is difficult to guarantee the size of the bubbles when they float out of the wastewater, and the gas after floating out of the wastewater is directly discharged from the device, which easily leads to large ozone bubbles being directly discharged from the ozone catalytic oxidation wastewater treatment equipment, resulting in ozone gas waste, this utility model provides a wastewater catalytic purification reaction tank.

[0006] The technical solution adopted by this utility model is: a wastewater catalytic purification reaction tank, comprising: a reaction treatment tank and a mixing mechanism disposed within the reaction treatment tank; the mixing mechanism includes multiple mixing components vertically arrayed within the reaction treatment tank, a drive mechanism fixed at the bottom end of the reaction treatment tank, an aeration nozzle disposed on the bottom surface of the inner wall of the reaction treatment tank, and a spraying mechanism fixed on the side of the reaction treatment tank; the mixing components include a first perforated plate fixed on the inner wall of the reaction treatment tank, multiple second perforated plates circumferentially arrayed at the output end of the drive mechanism, and multiple pulverizing blades circumferentially arrayed at the output end of the drive mechanism, the upper side of the pulverizing blades being in contact with the bottom surface of the first perforated plate, and the second perforated plates being located below the pulverizing blades.

[0007] Furthermore, the drive mechanism includes a servo motor fixed at the bottom of the reaction processing tank and a transmission shaft fixed at one end of the servo motor output shaft that extends into the reaction processing tank. The first mesh plate and the crushing blade are fixed to the side of the transmission shaft.

[0008] Furthermore, an air inlet valve is connected to one side of the aeration nozzle, with one end extending out of the reaction treatment tank. The upper side of the aeration nozzle is provided with a first through hole corresponding to the drive shaft, and the upper side of the first mesh plate is provided with a second through hole corresponding to the drive shaft.

[0009] Furthermore, the first mesh plate has a plurality of first mesh holes evenly distributed horizontally on its upper side, and the second mesh plate has a plurality of second mesh holes arranged in a rectangular array along its height direction on its side side. In the mixing mechanism, the diameter of the first mesh holes on the plurality of first mesh plates gradually decreases from the bottom to the top, and the diameter of the second mesh holes on the plurality of second mesh plates gradually decreases from the bottom to the top.

[0010] Furthermore, the spraying mechanism includes a high-pressure water pump connected to the lower part of the reaction treatment tank, a water outlet pipe fixed to the water outlet end of the high-pressure water pump, a spray nozzle fixed to the inner wall of the reaction treatment tank, an exhaust valve connected to the side of the reaction treatment tank, and a plurality of spray holes provided on the bottom surface of the spray nozzle.

[0011] Furthermore, the reaction treatment tank is connected to an inlet valve and an outlet valve on its side, and the bottom of the reaction treatment tank is provided with multiple raised legs.

[0012] The beneficial effects of this utility model are: By setting up aeration nozzles, ozone gas can be evenly sprayed into the wastewater in the reaction treatment tank, which can reduce the probability of forming large ozone gas bubbles and improve the mixing effect of ozone gas bubbles and wastewater. By setting a first mesh plate and a second mesh plate, ozone gas bubbles can be crushed and mixed with sewage through the second mesh on the second mesh plate, which can improve the mixing effect of ozone gas bubbles and sewage. Ozone gas bubbles larger than the diameter of the first mesh are blocked by the first mesh plate and crushed by the crushing blade, which can reduce the size of ozone gas bubbles and improve the mixing effect of ozone gas bubbles and sewage. By setting the diameter of the first mesh on the multiple first mesh plates from bottom to top in the mixing mechanism to gradually decrease, and the diameter of the second mesh on the multiple second mesh plates from bottom to top in the mixing mechanism to gradually decrease, it is convenient to further reduce the size of ozone gas bubbles and improve the mixing effect of ozone gas bubbles and sewage.

[0019] Furthermore, the drive mechanism 202 includes a servo motor 2021 fixed at the bottom of the reaction processing tank 1, a drive shaft 2022 fixed at one end of the output shaft of the servo motor 2021 that extends into the reaction processing tank 1, and a first mesh plate 2011 and a crushing blade 2013 fixed on the side of the drive shaft 2022.

[0020] Furthermore, an air inlet valve 205 is connected to one side of the aeration nozzle 203, with one end extending out of the reaction treatment tank 1. The upper side of the aeration nozzle 203 is provided with a first through hole 206 corresponding to the drive shaft 2022. A waterproof bearing is provided in the first through hole 206, and the lower part of the drive shaft 2022 is fixed in the waterproof bearing. This facilitates the improvement of the rotation stability of the drive shaft 2022 through the waterproof bearing and reduces the probability of sewage entering the aeration nozzle 203. The upper side of the first mesh plate 2011 is provided with a second through hole 207 corresponding to the drive shaft 2022.

[0021] Furthermore, the first mesh plate 2011 has multiple first mesh holes 2014 evenly distributed on its upper side, and the second mesh plate 2012 has multiple second mesh holes 2015 arranged in a rectangular array along its height direction on its side. In the mixing mechanism 2, the diameter of the first mesh holes 2014 on the multiple first mesh plates 2011 gradually decreases from bottom to top, and the diameter of the second mesh holes 2015 on the multiple second mesh plates 2012 gradually decreases from bottom to top.

[0022] Furthermore, the spraying mechanism 204 includes a high-pressure water pump 2041 connected to the lower part of the reaction treatment tank 1, a water outlet pipe 2042 fixed to the water outlet end of the high-pressure water pump 2041, a spray nozzle 2043 fixed to the inner wall of the reaction treatment tank 1, an exhaust valve 2044 connected to the side of the reaction treatment tank 1, and a plurality of spray holes 2045 provided on the bottom surface of the spray nozzle 2043. One end of the water outlet pipe 2042 extends into the reaction treatment tank 1 and is connected to the spray nozzle 2043.

[0023] Furthermore, the reaction treatment tank 1 is connected to an inlet valve 101 and an outlet valve 102 on its side, and the bottom of the reaction treatment tank 1 is provided with multiple raised legs 103.

[0024] Working principle: Wastewater is discharged into the reaction treatment tank 1 through the inlet valve 101. Ozone gas is evenly sprayed into the wastewater in the reaction treatment tank 1 through the air inlet valve 205 and the aeration nozzle 203. The aeration nozzle 203 reduces the probability of forming large ozone gas bubbles. The servo motor 2021 drives the transmission shaft 2022 to rotate the second mesh plate 2012, causing the ozone gas bubbles to be crushed and mixed with the wastewater through the second mesh 2015 on the second mesh plate 2012, which improves the mixing effect of ozone gas bubbles and wastewater. Ozone gas bubbles larger than the first mesh 2014 on the first mesh plate 2011 are blocked by the first mesh plate 2011. The crushing blade 2013 cuts the ozone gas bubbles blocked by the first mesh plate 2011, which reduces the size of the ozone gas bubbles. The diameter of the first mesh 2014 on the multiple first mesh plates 2011 from bottom to top in the mixing mechanism 2 gradually decreases, and the diameter of the second mesh 2015 on the multiple second mesh plates 2012 from bottom to top in the mixing mechanism 2 gradually decreases. This facilitates a gradual reduction in the size of ozone gas bubbles, improving the mixing effect between ozone gas bubbles and wastewater. When the ozone gas bubbles float out of the wastewater and burst, the gas pressure in the reaction treatment tank 1 increases, and the ozone gas moves upward. The high-pressure water pump 2041 drives the wastewater to be sprayed downward through the spray nozzle 2043 to mix with the rising ozone gas. This further improves the mixing effect between ozone gas bubbles and wastewater, reducing the probability of ozone gas waste. Then, the ozone gas after the reaction is discharged from the reaction treatment tank 1 through the exhaust valve 2044.
