Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to an ozone generator for sludge treatment. Background Art

[0002] An ozone generator is a device used to produce ozone gas (O 3 ) and usually generates ozone gas by polymerizing part of the oxygen in the air through a high-pressure separation method, or ozone can also be obtained by electrolyzing water. Ozone is easy to decompose and cannot be stored, so it needs to be produced and used on-site. Therefore, an ozone generator is required wherever ozone is used. Ozone generators are widely used in the fields of drinking water, sewage, industrial oxidation, food processing and preservation, pharmaceutical synthesis, space sterilization, etc., demonstrating their important role and broad application prospects in different industries.

[0003] Sludge ozone purification refers to a method of purifying and disinfecting sludge with ozone as an oxidant. In the existing ozone generation equipment for sludge treatment, although sludge purification is achieved with ozone, problems such as slow ozone diffusion speed in sludge, uneven dispersion, and inability to fully contact the sludge will all result in insufficient sludge purification treatment. Summary of the Invention

[0004] In order to overcome the technical problems of incomplete and insufficient sludge purification treatment, the utility model provides an ozone generator for sludge treatment.

[0005] The ozone generator for sludge treatment provided by the utility model adopts the following technical scheme:

[0006] An ozone generator for sludge treatment includes a sludge pump, an ozone generator, a micro-nano bubble generator, a reaction tank, a sedimentation tank, an ultrasonic disperser, a dehydration device, and a sludge storage tank. The sludge pump is connected to the reaction tank through a pipeline. The ozone generator is connected to the micro-nano bubble generator. The nozzle of the micro-nano bubble generator is connected to the reaction tank. The reaction tank is connected to the sedimentation tank through a pipeline. The ultrasonic disperser is fixedly arranged in the reaction tank. The sludge outlet at the bottom of the sedimentation tank is connected to the dehydration device through a pipeline. The dehydration device is connected to the sludge storage tank.

[0007] By adopting the above technical solution, the ozone generator is connected to the micro-nano bubble generator, and the nozzle of the micro-nano bubble generator is connected to the reaction tank. That is, ozone enters the reaction tank through the micro-nano bubble generator, so that ozone can penetrate into every corner of the reaction tank and come into full contact with the sludge, realizing more efficient sludge purification. In addition, by fixedly arranging the ultrasonic disperser in the reaction tank, the sludge to be treated can be dispersed in the sewage, avoiding the influence of sludge deposition on the contact efficiency between ozone and sludge. On the other hand, the ultrasonic disperser can help the ozone combined with the micro-nano bubbles to be quickly and evenly dispersed into every corner of the reaction tank, improving the efficiency and quality of sludge purification.

[0008] Preferably, an ozone generator for sludge treatment further includes a sewage treatment tank. The sewage outlet in the middle of the sedimentation tank is connected to the sewage treatment tank through a pipeline, and the sewage treatment tank is connected to the ozone generator.

[0009] Preferably, the dehydration device is connected to the sewage treatment tank through a pipeline.

[0010] By adopting the above technical solution, by setting up the sewage treatment tank and connecting the ozone generating device to the sewage treatment tank, the sewage after removing the sludge can be further purified to meet the discharge standard. The dehydration device is connected to the sewage treatment tank, and the dewatered sewage can be sent to the sewage treatment tank for purification and then discharged together.

[0011] Preferably, a first flow control valve is arranged on the pipeline connecting the ozone generator and the micro-nano bubble generator, and a second flow control valve is arranged on the pipeline connecting the ozone generator and the sewage treatment tank.

[0012] By adopting the above technical solution, by arranging the first flow control valve on the pipeline connecting the ozone generator and the micro-nano bubble generator and the second flow control valve on the pipeline connecting the ozone generator and the sewage treatment tank, the corresponding ozone supply amount can be adjusted according to the conditions in the reaction tank and the sewage treatment tank to realize the full utilization of ozone.

[0013] Preferably, the reaction gas outlet at the upper part of the reaction tank and the reaction gas outlet at the upper part of the sewage treatment tank are both connected to the tail gas absorption tank.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. An ozone generator for sludge treatment of the present utility model is configured such that the ozone generator is connected to a micro-nano bubble generator, and the nozzle of the micro-nano bubble generator is connected to a reaction tank. That is, ozone enters the reaction tank through the micro-nano bubble generator, enabling the ozone to reach every corner of the reaction tank and come into full contact with the sludge, thus purifying the sludge more thoroughly. Additionally, by fixedly installing an ultrasonic disperser in the reaction tank, the sludge to be treated can be dispersed in the sewage, preventing sludge deposition from affecting the efficiency of ozone-sludge contact. On the other hand, the ultrasonic disperser helps the ozone combined with micro-nano bubbles to be quickly and evenly dispersed to every corner of the reaction tank, improving the efficiency and quality of sludge purification.

An ozone generator for sludge treatment of the present utility model is configured with a sewage treatment tank, and the ozone generating device is connected to the sewage treatment tank, enabling further purification of the sewage after sludge removal to meet the discharge standards.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further elaborates on the present utility model in conjunction with the Figure 1 drawings.

[0021] This embodiment discloses an ozone generator for sludge treatment. Refer to Figure 1, including a sludge pump 1, an ozone generator 2, a micro-nano bubble generator 3, a reaction tank 4, a sedimentation tank 5, an ultrasonic disperser 6, a dehydration device 7 and a sludge storage tank 8. The sludge pump 1 is connected to the reaction tank 4 through a pipeline. The sludge to be treated is pumped into the reaction tank 4 through the sludge pump 1. The ozone generator 2 is the main equipment for sludge treatment. The ozone generator 2 is connected to the reaction tank 4 through the micro-nano bubble generator 3. The micro-nano bubbles have very small sizes. Ozone enters the reaction tank 4 after passing through the micro-nano bubble generator 3, which can transfer ozone to every molecule of the sludge, making the sludge purification more uniform and efficient. The reaction tank 4 is connected to the sedimentation tank 5 through a pipeline. The sludge treated by ozone enters the sedimentation tank 5 from the reaction tank 4. A sewage outlet 51 is opened in the middle of the sedimentation tank 5, and a sludge outlet 52 is opened at the bottom. The sludge outlet 52 at the bottom of the sedimentation tank 5 is connected to the dehydration device 7 through a pipeline. The dehydration device 7 is connected to the sludge storage tank 8. That is, the treated sludge enters the dehydration device 7 for dehydration treatment. After dehydration, the sludge is discharged into the sludge storage tank 8. The dehydrated and dried sludge can be used for agriculture, landscaping or building materials, and can also be converted into energy products for utilization. An ultrasonic disperser 6 is also fixedly arranged in the reaction tank 4. The ultrasonic disperser 6 quickly disperses the sludge evenly through the acoustic pressure and shear force generated when ultrasonic waves propagate in the liquid, so as to avoid the influence of sludge deposition on the efficiency of ozone contact with the sludge. The ultrasonic disperser 6 can also help the ozone combined with the micro-nano bubbles to be quickly and evenly dispersed into every corner of the sludge, improving the efficiency and quality of sludge purification.

[0022] Among them, as Figure 1 shown, an ozone generator for sludge treatment further includes a sewage treatment tank 9. The sewage outlet 51 in the middle of the sedimentation tank 5 is connected to the sewage treatment tank 9 through a pipeline. The dehydration device 7 is also connected to the sewage treatment tank 9 through a pipeline. That is, after the sludge in the sedimentation tank 5 undergoes sedimentation and stratification, the upper-layer sewage enters the sewage treatment tank 9 through the sewage outlet 51, and the lower-layer sludge enters the dehydration device 7. At the same time, the sewage generated in the dehydration device 7 also returns to the sewage treatment tank 9. The ozone generator 2 is connected to the sewage treatment tank 9. That is, the ozone generator 2 provides ozone to the sewage treatment tank 9 to further purify the sewage so as to meet the discharge standard.

[0023] Among them, as Figure 1 shown, a first flow control valve 21 is arranged on the connecting pipeline between the ozone generator 2 and the micro-nano bubble generator 3, and a second flow control valve 22 is arranged on the connecting pipeline between the ozone generator 2 and the sewage treatment tank 9. According to the sludge and sewage treatment conditions in the reaction tank 4 and the sewage treatment tank 9, the first flow control valve 21 and the second flow control valve 22 are adjusted accordingly, which can timely adjust the ozone supply amount in the reaction tank 4 and the sewage treatment tank 9 to realize the full utilization of ozone.

[0024] Among them, asFigure 1 As shown, the reaction gas outlets at the upper part of the reaction tank 4 and the reaction gas outlets at the upper part of the sewage treatment tank 9 are both connected to the tail gas absorption tank 10. There is still a certain amount of ozone in the tail gas discharged from the reaction tank 4 and the sewage treatment tank 9. If it is directly discharged into the atmosphere, it will cause atmospheric environmental pollution. Therefore, it is necessary to further process it through the tail gas absorption tank 10 to meet the emission standards.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention still belongs to the protection scope of the technical solution of the present invention.
