Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an ozone disinfection device for wastewater treatment. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse. Ozone disinfection refers to water treatment technology that uses ozone as a disinfectant. Ozone is a strong oxidant that, when dissolved in water, directly or indirectly oxidizes inorganic and organic matter in water using a large number of hydroxyl radicals and nascent oxygen generated during the reaction. It also enters the cells of bacteria to oxidize intracellular organic matter, thereby achieving the purpose of sterilization, disinfection, and water purification.

[0003] The announcement number is CN218910007U, which discloses "an ozone disinfection device for wastewater treatment, including a mixing tank, an inlet pipe fixedly connected to the top of one side of the mixing tank, a mixing and dispersing mechanism installed inside the mixing tank, an ozone generator installed on one side of the bottom of the mixing tank, a one-way valve installed between the mixing tank and the ozone generator, a wastewater transmission pipe fixedly connected to the bottom of the mixing tank, a valve and an impeller pump respectively installed on the wastewater transmission pipe, an ozone output pipe fixedly connected to the top of the mixing and dispersing mechanism, and a secondary contact mechanism provided between the wastewater transmission pipe and the ozone output pipe at the end away from the mixing tank".

[0004] There are still some drawbacks in its use. The reaction takes place inside a single mixing tank, and the large amount of wastewater in the tank makes it difficult for the wastewater to come into contact with ozone, resulting in a slower ozone oxidation rate. In addition, ozone usually comes into contact with the wastewater at the discharge point first, and it is not easy to react quickly with wastewater at a more distant location. It is also not easy for wastewater at different heights to come into direct contact with ozone, resulting in less contact between the upper layer of wastewater and ozone, and a slower reaction rate. Utility Model Content

[0005] The purpose of this invention is to provide an ozone disinfection device for wastewater treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An ozone disinfection device for wastewater treatment, comprising:

[0008] A reaction chamber, wherein multiple stirring cylinders are fixedly installed inside the reaction chamber;

[0009] The transmission assembly is fixedly installed on the upper surface of the reaction chamber;

[0010] A gas distribution assembly is fixedly installed at the lower end of the reaction chamber. The gas distribution assembly includes multiple connecting pipes fixedly installed on the lower surface of the reaction chamber. Multiple gas distribution pipes are fixedly installed at equal intervals on the outer surface of each connecting pipe, and multiple gas outlet pipes are fixedly installed at equal intervals on the outer surface of each gas distribution pipe.

[0011] Furthermore, a baffle is fixedly installed inside the reaction chamber at the upper end of the outer surface of multiple stirring cylinders, and a water inlet pipe is fixedly embedded at the upper end of the outer surface of the reaction chamber.

[0012] Furthermore, multiple water collection pipes are fixedly installed on the lower surface of the reaction chamber, and multiple water outlet pipes that are fixedly connected to the stirring drum are fixedly installed on the outer surface of the water collection pipes. A No. 1 multi-port pipe is fixedly installed at one end of each of the multiple water collection pipes.

[0013] Furthermore, the air outlet pipe is fixedly connected to the adjacent stirring drum, a one-way valve is fixedly installed inside the air outlet pipe, and a No. 2 multi-port pipe is fixedly installed at one end of each of the multiple connecting pipes.

[0014] Furthermore, a spiral blade is rotatably connected inside the stirring drum, and a rotating frame that penetrates the reaction chamber is fixedly installed at the upper end of the spiral blade.

[0015] Preferably, the transmission assembly includes:

[0016] The outer casing is fixedly installed on the upper surface of the reaction chamber;

[0017] Multiple No. 1 bevel gears are fixedly installed on the upper end of multiple rotating frames;

[0018] Multiple No. 1 fixing rings are fixedly installed inside the outer shell;

[0019] Multiple No. 1 rotating shafts are rotatably connected inside multiple No. 1 fixed rings;

[0020] Multiple second bevel gears are fixedly installed at equal intervals on the outside of the first rotating shaft, and are meshed with the first bevel gear at the corresponding position for transmission.

[0021] Preferably, a plurality of second fixing rings are fixedly installed on one side surface inside the outer shell, and a second rotating shaft is rotatably connected inside the plurality of second fixing rings. A third bevel gear is fixedly installed on the outer surface of the second rotating shaft and one end of the first rotating shaft. Two adjacent third bevel gears are meshed and connected for transmission. A motor capable of driving the second rotating shaft is fixedly installed on one side surface of the outer shell.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. Wastewater flows into multiple mixing drums separately. After ozone disinfection, the wastewater flows through the outlet pipe and is discharged from the No. 1 multi-port pipe. By setting up multiple mixing drums inside the reaction chamber, the wastewater enters multiple mixing drums to react, reducing the cross-sectional area of ​​the wastewater in a single space and facilitating the reaction between ozone and wastewater.

[0024] 2. Multiple air outlet pipes are connected to the mixing drum at different heights, and each mixing drum is connected to three air outlet pipes at the same height. This allows ozone to be injected into the mixing drum at different heights in the form of fine bubbles, so that wastewater at different heights can directly contact ozone, ensuring that wastewater at different heights can be exposed to a large amount of ozone, thereby accelerating the ozone oxidation rate.

[0025] 3. The motor operates, driving multiple rotating frames to rotate, causing the spiral blades to rotate. This agitates the wastewater on the outside to flow downwards and the wastewater on the inside to flow upwards. The pressure from the rotation accelerates the contact between the wastewater and ozone, thereby further improving the ozone disinfection efficiency. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-5 In this embodiment of the present invention, an ozone disinfection device for wastewater treatment includes a reaction chamber 1, a plurality of stirring cylinders 101 are fixedly installed inside the reaction chamber 1, a transmission assembly 2 is fixedly installed on the upper surface of the reaction chamber 1, and a gas distribution assembly 3 is fixedly installed on the lower end of the reaction chamber 1. The gas distribution assembly 3 includes a plurality of connecting pipes 301 fixedly installed on the lower surface of the reaction chamber 1, a plurality of gas distribution pipes 303 are fixedly installed at equal intervals on the outer surface of the connecting pipes 301, and a plurality of gas outlet pipes 304 are fixedly installed at equal intervals on the outer surface of the gas distribution pipes 303.

[0034] Specifically, the gas distribution component 3 is connected to an external ozone generator, which disperses and injects ozone into the interior of multiple stirring drums 101, allowing the ozone to enter the wastewater in the form of fine bubbles, thereby increasing the contact area between the ozone and the wastewater and accelerating the reaction rate.

[0035] Example 1

[0036] like Figure 1-3 As shown, in this embodiment, a baffle 106 is fixedly installed inside the reaction chamber 1 at the upper end of the outer surface of multiple stirring cylinders 101, and a water inlet pipe 108 is fixedly embedded at the upper end of the outer surface of the reaction chamber 1; multiple water collection pipes 104 are fixedly installed on the lower surface of the reaction chamber 1, and multiple water outlet pipes 103 that are fixedly connected to the stirring cylinders 101 are fixedly installed on the outer surface of the water collection pipes 104, and a No. 1 multi-port pipe 105 is fixedly installed at one end of the multiple water collection pipes 104.

[0037] In this embodiment, the inlet pipe 108 is used for wastewater injection. The wastewater flows into the interior of multiple stirring drums 101 above the baffle 106. After the wastewater is disinfected by ozone, it flows through the outlet pipe 103 and is discharged from the first multi-port pipe 105. Thus, by setting multiple stirring drums 101 inside the reaction chamber 1, the wastewater enters the interior of multiple stirring drums 101 to react, reducing the cross-sectional area of ​​the wastewater in a single space and facilitating the reaction between ozone and wastewater.

[0038] like Figure 2 and Figure 5 As shown, in this embodiment, the vent pipe 304 is fixedly connected to the adjacent stirring drum 101, a one-way valve is fixedly installed inside the vent pipe 304, and a second multi-way pipe 302 is fixedly installed at one end of multiple connecting pipes 301.

[0039] In practice, multiple vent pipes 304 are connected to the mixing drum 101 at different heights, and each mixing drum 101 is connected to three vent pipes 304 at the same height, so that ozone is injected in the form of fine bubbles at different heights of the mixing drum 101, so that wastewater at different heights can directly contact ozone, ensuring that wastewater at different heights can come into contact with more ozone, thereby accelerating the ozone oxidation rate.

[0040] Example 2

[0041] Based on Example 1, in order to overcome the problem that wastewater can only passively react with ozone when left to stand,

[0042] like Figure 1 and Figure 4 As shown, in this embodiment, the transmission component 2 includes: a housing 201 fixedly installed on the upper surface of the reaction chamber 1; multiple first bevel gears 202 fixedly installed on the upper ends of multiple rotating frames 107; multiple first fixing rings 203 fixedly installed inside the housing 201; multiple first rotating shafts 204 rotatably connected to the interior of the multiple first fixing rings 203; multiple second bevel gears 205 equidistantly fixedly installed on the outer side of the first rotating shafts 204 and meshing with the first bevel gears 202 at corresponding positions for transmission connection; multiple second fixing rings 206 are fixedly installed on one side surface inside the housing 201; second rotating shafts 207 are rotatably connected inside the multiple second fixing rings 206; third bevel gears 208 are fixedly installed on the outer surface of the second rotating shafts 207 and one end of the first rotating shafts 204; adjacent third bevel gears 208 mesh for transmission connection; and a motor 209 capable of driving the second rotating shafts 207 to rotate is fixedly installed on one side surface of the housing 201.

[0043] In practice, the motor 209 operates, driving the second rotating shaft 207 to rotate. Through the transmission of the third bevel gear 208, the first rotating shaft 204 rotates. Through the transmission of the first bevel gear 202 and the second bevel gear 205, multiple rotating frames 107 rotate, causing multiple spiral blades 102 to rotate synchronously, stirring the wastewater inside the mixing drum 101, allowing the wastewater to fully contact the ozone and accelerating the reaction rate.

[0044] like Figure 2 As shown, in this embodiment, a spiral blade 102 is rotatably connected inside the stirring tank 101, and a rotating frame 107 that penetrates the reaction chamber 1 is fixedly installed on the upper end of the spiral blade 102.

[0045] In practice, the spiral blades 102 rotate, stirring the wastewater on the outside to flow downwards and the wastewater on the inside to flow upwards. The pressure from the rotation accelerates the contact between the wastewater and ozone, thereby further improving the disinfection efficiency of ozone.
