Description

Technical Field

[0001] The utility model relates to wastewater treatment, in particular to an ozone generating and oxidizing device for printing and dyeing wastewater treatment. Background Art

[0002] The printing and dyeing industry is a typical high-water consumer. The sources and pollutant composition of the wastewater produced are very complex, with significant variations in water quality, high organic content, and high chroma (primarily from colored dyes). Direct discharge poses significant risks to human health and the living environment, while also resulting in a waste of water resources. Advanced treatment is a key step in the treatment of printing and dyeing wastewater. Using ozone, with its strong oxidizing properties as an oxidant, it effectively removes wastewater containing water-soluble and disperse dyes.

[0003] Currently, when ozone generators are used to treat printing and dyeing wastewater, the ozone is typically introduced into a reaction tank. The ozone reacts with harmful substances in the wastewater through aeration, and then chemicals are manually added to the wastewater to enhance the ozone's effectiveness. The ozone generation and oxidation process is complex, making it difficult to accurately measure the harmful substance content in the wastewater and control the amount of chemicals added, which can easily lead to chemical waste. For these reasons, it is necessary to design a device that can produce snow and ice of appropriate quality based on the capacity of the container. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of the present utility model is to provide an ozone generating and oxidizing device for treating printing and dyeing wastewater, so that the ozone generating and oxidizing device can accurately grasp the content of harmful substances in the wastewater and perform intelligent control of the output ozone and the addition of chemicals.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] An ozone generating and oxidizing device for treating printing and dyeing wastewater comprises a reaction tank, an ozone generator and a plurality of aeration devices which are arranged through the reaction tank, wherein the plurality of aeration devices are arranged on the bottom wall of the reaction tank, a through-tube is horizontally arranged in the middle of the reaction tank and above the plurality of aeration devices, a plurality of shuttle-shaped output pipes are evenly arranged on the through-tube, a control box is arranged through the upper side of the through-tube, a storage box is arranged through the upper side of the control box, and a plurality of detection components are arranged on the outside of the reaction tank for controlling the switch and dosage of ozone and reagents by the ozone generating and reaction device.

[0007] Preferably, the through-tube is connected to a plurality of shuttle-shaped output tubes, and the control box and the storage box are both located above the reaction tank.

[0010] Preferably, a rotating motor is provided at one end of the control box close to the storage box, a sealing plate is provided at the output end of the rotating motor, the sealing plate is rotatably provided in the control box, and a flow sensor is provided inside the other end of the control box.

[0011] Preferably, a pressure pump is horizontally provided at the end of the through-tube, and the pressure pump is located outside the reaction tank.

[0012] Preferably, the detection component includes a pH detection probe and a concentration meter that are arranged throughout the reaction tank.

[0013] Preferably, the ozone generating and oxidizing device further comprises a controller, wherein the controller is provided with an indicator light group connected to the detection component.

[0014] Compared to existing technologies, the ozone generation and oxidation device provided by this utility model can detect harmful levels of wastewater at different locations within the reaction tank, intelligently control the addition of ozone and reagents, and avoid resource waste.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are described in more detail below in conjunction with the drawings of the embodiments. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] As attached Figure 1 and attached Figure 2 As shown, the ozone generating and oxidizing device provided by the embodiment of the present invention can detect the wastewater at different positions in the reaction tank, intelligently control the amount of ozone and reagent added, and avoid waste of resources. According to the existing printing and dyeing wastewater treatment technology, Figure 1 and 2As shown, after the treatment, the printing and dyeing wastewater will be introduced into the reaction tank, and then oxygen will be introduced into the ozone generator 11. The ozone generator 11 uses the principle of high-voltage discharge to convert oxygen into ozone, which is introduced into multiple aeration devices 12 in the reaction tank. Ozone is injected into the wastewater in the reaction tank for oxidation treatment. Among them, a through-tube can be arranged through the middle of the interior of the reaction tank, and the through-tube 2 is arranged on the upper side of the multiple aeration devices 12. A plurality of shuttle-shaped output pipes 21 are evenly arranged on the through-tube 2. Through the output of the reagent in the shuttle-shaped output pipe 21, the reagent can be quickly dispersed into the wastewater using the power of aeration ozone, thereby improving the addition rate and reaction speed of the reagent. A control box 3 is arranged on the upper side of the through-tube 2, and a storage box 4 is arranged on the upper side of the control box 3. A plurality of detection components 6 are arranged on the outside of the reaction tank for switching and controlling the dosage of ozone and reagents in the ozone generation and reaction device. When the ozone generation and oxidation device is in use, a catalytic agent is added to the storage box 4. With the addition of liquid water, the agent can be dissolved into a liquid. The control box 3 then controls the switch of the storage box 4. Multiple detection components 6 detect the sewage quality at different positions in the reaction tank, which can quickly detect the content and pH value of harmful positions in the wastewater, and timely control the amount of added agents to avoid excessive agents and waste of resources.

[0027] It is worth mentioning that, Figure 1 and 4 As shown, the through-tube 2 is connected with a plurality of shuttle-shaped output tubes 21, and the control and storage box 4 is located above the reaction pool, so that external personnel can add reagents and liquid water into the storage box 4 to make liquid reagents. Through the storage of liquid reagents in the storage box 4 and the switch control of the storage box 4 by the control box 3, the control box 3 introduces reagents into the through-tube 2, and then through the setting of the shuttle-shaped output tube 21, the reagents can be explosively sprayed to the surroundings, and at the same time, the reagents are added to the reaction pool in multiple directions.

[0028] In order to better add the agent to the wastewater, such as Figure 3 As shown, in some embodiments, a shuttle-shaped output tube 21 is used, and a plurality of output ports 211 are provided in a ring shape in the middle of the shuttle-shaped output tube 21, so that the reagent can be explosively sprayed out in the reaction pool; and by the sleeve of the turn-out cover 212 on the shuttle-shaped output tube 21, the turn-out cover 212 is also provided with an output port 211. When the reagent is output from the shuttle-shaped output tube 21, the turn-out cover 212 is flushed, and a water ring is formed between the turn-out cover 212 and the shuttle-shaped output tube 21. The turn-out cover 212 is suspended in the shuttle-shaped output filling; and then, by the opening of the output ports 211 on the two structures, the reagent is sprayed out while the turn-out cover 212 is driven to rotate, and the angle of the sprayed reagent is adjusted to realize the rotation of the output direction of the reagent, and the reagent is sprayed at different positions of the reaction pool, thereby improving the reaction effect of the reagent and the wastewater, providing convenience for the detection of wastewater in the detection component 6, increasing the convenience of reagent addition, and saving operation steps.

[0029] When the reagent is added to the wastewater quickly, the structure of the shuttle-shaped output pipe 21 can be further improved, such as Figure 3 As shown, a pressurizing plate 213 is disposed within the shuttle-shaped output tube 21, with a through-hole formed in the middle thereof. When the agent is introduced into the shuttle-shaped output tube 21, the pressurizing plate 213 allows the agent to pass through the through-hole in the middle of the plate 213, thereby increasing the agent's flow rate, broadening the spraying area, and improving the uniformity of agent addition. This facilitates a rapid reaction between the agent and the wastewater, facilitates timely wastewater quality testing by the detection assembly 6, saves processing steps and labor costs, and is beneficial to the device's agent addition process.

[0030] In order to further facilitate the control box 3 to control the amount of added medicine, such as Figure 4 As shown, a rotary motor 32 is provided at one end of the control box 3 near the storage box 4, and a sealing plate 31 is provided at the output end of the rotary motor 32. The sealing plate 31 is rotatably provided in the control box 3, and a flow sensor 33 is provided inside the other end of the control box 3. The size of the sealing plate 31 matches the size of the inner wall of the control box 3. In this embodiment, the flow sensor 33 uses a liquid flow sensor 33; the power output of the rotary motor 32 can drive the sealing plate 31 to rotate in the control box 3, control the storage box 4 to open, and the medicine in the box passes through the sealing plate 31 by gravity and flows into the control box 3 and then flows into the through-tube 2. The flow rate of the liquid is detected by the flow sensor 33, and the amount of medicine flowing through is detected in real time. The data is then transmitted to the existing controller of the device through the sensor, so that the controller can display the detection data, which is also the total amount of added medicine, and record the amount of medicine added, thereby realizing the automatic control of medicine addition.

[0031] For better pharmaceutical addition, such as Figure 1 and 4 As shown, in some embodiments, a pressure pump 5 can be set at the end of the through-tube 2, and the gas output end of the pressure pump 5 is set horizontally, and the pressure pump 5 is set on the outside of the reaction tank to reduce the impact of wastewater on the pressure pump 5 and facilitate the transportation of external gas to the through-tube 2; when the ozone generation and oxidation device adds ozone to the wastewater, the pressure pump 5 can be used to drive the low-pressure gas at the large-area piston end to generate high-pressure gas at the small-area piston end, thereby increasing the air pressure in the through-tube 2 and improving the ozone transportation rate.

[0032] It is worth mentioning that, Figure 5As shown, when the detection component 6 is set, it can be set in different positions of the reaction tank, such as in the middle of the side wall of the reaction tank and at the four corners of the reaction tank; the detection component 6 includes a pH value detection probe 61 and a concentration meter 62 set through the reaction tank. When the detection component 6 is used, it will be connected to the existing controller of the device, and the existing wastewater detection pH value and liquid concentration detection technology will be applied. The device can obtain the pH value and liquid concentration of the wastewater at different positions in the reaction tank, and then transmit the detection data to the controller. After taking the average value, it is convenient for the operator to grasp the harmful substance content of the wastewater, understand the ozone wastewater treatment situation and the wastewater treatment situation after adding the agent, and can timely control the addition of the agent and the input of ozone, increase the accuracy of the oxidation treatment of the device, avoid the waste of ozone and agents, and increase the energy saving and wastewater treatment rate of the ozone generation and oxidation device.

[0033] Further improvement of the detection component 6 makes it easier for operators to quickly control the addition of ozone and reagents, such as Figure 5 As shown, an indicator light group 63 with the same number as the detection component 6 can be set on the controller of the existing device, wherein the indicator light group 63 is composed of lights of different colors, and the switch of each light is controlled by the controller. Before the indicator light group 63 is used, the lighting value of the indicator light will be displayed according to the pH value and concentration of the qualified wastewater after deep treatment of the device. When the detection component 6 detects data and transmits it to the controller, the controller judges the data and turns on indicator lights of different colors. The operator manually controls the control box 3, and the control box 3 can also be automatically controlled to control its switch, thereby realizing the intelligent delivery of ozone and chemicals, saving the operating steps of the device, controlling the addition of ozone and chemicals, and avoiding waste of resources.

[0034] Working principle: When the ozone generation and reaction device is used to treat printing and dyeing wastewater, the pH value and concentration of the qualified wastewater are first set on the controller of the device according to the wastewater treatment requirements, and then the catalyst and liquid water are added to the storage tank 4 to make the agent into liquid; then, according to the detection of the detection component 6 at different positions on the reaction tank, the pH value detection probe 61 and the concentration meter 62 transmit the pH value and concentration data of the wastewater at the location to the control, compare them with the preset value on the controller, and light up the indicator light of the corresponding color; control the ozone generator 11 to open, and produce ozone after high-pressure treatment of oxygen, and then lead it to multiple aeration devices 12, and the ozone is injected into the wastewater through the aeration treatment of the aeration device 12; at the same time, open the control box 3, and drive the sealing plate 31 with the power of the rotating motor 32 to open the storage tank 4, and inject the liquid into the ozone generator 11. After passing through the sealing plate 31, it enters the through-tube 2, and the flow meter detects the capacity of the liquid flowing through in real time; then, the reciprocating pressure of the small-area piston of the pressure pump 5 is increased to increase the liquid pressure, so that the agent quickly enters the through-tube 2 and is output from the multiple output ports 211 of the multiple shuttle-shaped output tubes 21, and drives the outer rotation cover 212 to automatically rotate the output direction of the liquid, and explosively fill it into the wastewater. The ozone is injected into the wastewater through the aeration device 12, and can quickly react with the wastewater for oxidation treatment; then, through real-time detection of the detection components 6 at different positions in the reaction tank and display of data and indicator lights on the controller, the switches of the ozone generator 11 and the control box 3 can be intelligently controlled to stop the addition of ozone and agents, completing the wastewater treatment of the device, saving operating steps, reducing resource consumption, and improving the processing rate of the device.

[0035] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
