Description

Technical Field

[0001] The present invention relates to the technical field of laundry systems, and particularly to a laundry factory with a sewage treatment system. Background Art

[0002] Traditional laundry factories use laundry detergent or chemical detergents as the main cleaning and decontamination materials. After years of improvement, their cleaning ability has reached a relatively high level. However, the detergent components make the sewage complex and are not conducive to the environmental ecology. The surfactants in the detergents are prone to generating dirt in the laundry tub, which is likely to cause secondary pollution. At the same time, the residual amount of detergents can still harm the human skin and cause allergic reactions and other drawbacks. Especially in the system architecture of multiple washing machines in self-service laundries or laundry factories, the cost of recycling the washed sewage is too high, and usually the washed sewage is directly discharged, resulting in a waste of water resources. Summary of the Invention

[0003] In order to solve the problems of high cost of sewage recycling in existing laundry factories, which leads to direct discharge of sewage, causing environmental pollution and waste of water resources, the present invention provides a laundry factory with a sewage treatment system.

[0047] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] In the embodiments provided by the present invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0049] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present invention. Therefore, the "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. Those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0050] In various embodiments of the present invention, it should be understood that the magnitude of the sequence numbers of the above processes does not necessarily mean the inevitable sequence of execution. The execution sequence of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0051] Traditional washing equipment uses a washing method of "mechanical agitation + chemical detergent", which has problems such as large water consumption, large detergent consumption, high energy consumption, and serious environmental pollution. With the continuous innovation of washing technology, washing modes without chemical detergents, such as micro-nano bubble washing, ion water washing, and microparticle washing, gradually replace the traditional washing mode. Among them, the research on the generation method of micro-nano bubbles started early and is applicable to many fields, such as drinking water and sewage treatment, groundwater purification, biomedical engineering, and other industrial applications, such as washing, agriculture, fishery, and food. However, for some specific fields, such as the architecture of multiple laundry equipment in a laundry factory or a laundry, the prior art directly discharges the washing sewage after laundry, which is extremely wasteful of water resources and is likely to generate a large economic cost, and the economy is poor. Therefore, it is particularly important to seek a method for recycling and treating the sewage generated by the architecture of multiple laundry equipment in a laundry factory or a laundry.

[0052] It should be noted that in the prior art, the common method for treating sewage is to treat the sewage into drinking water. When dealing with application scenarios such as a laundry factory or a laundry, the treatment cost is too high. Therefore, the sewage discharged from multiple laundry equipment in a laundry factory or a laundry usually chooses to be directly discharged and does not choose to be recycled.

[0053] Please refer to Figure 1 , Figure 1Flowchart of the sewage treatment system 10 of the present invention. After the laundry wastewater discharged from the laundry equipment 1 is discharged, it is conveyed to the filter barrel by a water pump for retention, and then passes through the filtering device 2 with the function of screening granular materials by gravity or water pump. The filtrate collected at the bottom of the filtering device 2 is conveyed to the sewage treatment device 3 by gravity or water pump. The sewage treatment device 3 includes an oxidation treatment device 31 and an oxidation gas generator 32 (not shown in the above figure), so that the filtered sewage is subjected to sewage oxidation treatment in the oxidation treatment device 31 of the sewage treatment device 3, and the oxidation gas generated by the oxidation gas generator 32 acts as an oxidant for oxidizing sewage pollutants. The primary recycled water after the oxidation treatment of the sewage treatment device 3 is further conveyed to the bubble generation device 4 by a water pump to further treat the primary recycled water.

[0054] Refer to Table 1, which is Figure 1 One example of the water quality analysis of the laundry wastewater discharged from the laundry equipment 1 in the table, which is for the laundry equipment 1 using hydrogen nano-microbubbles for laundry.

[0055]

[0056] The primary recycled water after the oxidation treatment by the sewage treatment device 3 carries some oxidation gas. Further, after the gas-liquid pressurization and mechanical cutting action of the bubble generation device 4, the oxidation gas will form more and finer oxidation gas nano-microbubbles.

[0057] As Figure 1 described in the process, when the recycled water leaving the bubble generation device 4 flows back into the laundry equipment 1, the cleanliness of the recycled water can be approximated to that of the tap water at the initial inlet, and for the laundry equipment 1 using hydrogen nano-microbubbles for laundry, the parameters such as the number of hydrogen nano-microbubbles and the pH value contained in the recycled water are close to those of the washing liquid during the washing operation of the laundry equipment 1. Therefore, it can greatly save the use of tap water and reduce the time and resource consumption for preparing hydrogen nano-microbubble washing liquid from tap water.

[0058] Please refer to Figure 2A and Figure 2B which are respectively Figure 1 Schematic diagrams of the sewage treatment device 3 and the bubble generation device 4 shown in the flowchart of the sewage treatment system of the present invention.

[0059] Figure 2AThe sewage treatment device 3 shown includes an oxidation treatment device 31, an oxidation gas generator 32, a sewage electrolysis module 33, and a water pump 34; the inlet end of the oxidation treatment device 31 is connected to the output end of the laundry sewage generated by the laundry equipment 1, and the oxidation gas generator 32 generates oxidation gas. Specifically, the oxidation gas generator 32 is used to generate oxidation gas such as oxygen or ozone that has the ability to oxidize pollutants in sewage and transport it to the oxidation treatment device 31, so that the oxidation gas and the laundry sewage are oxidatively decomposed in the oxidation treatment device 31, and the output end of the oxidation treatment device 31 is connected to the sewage electrolysis module 33. Through electrolysis, the oxidation gas nanometer microbubbles output by the oxidation treatment device 31 are formed into primary recycled water.

[0060] It should be noted that the oxidation gas generator 32 can also be replaced by cylinders of oxygen or ozone, etc.

[0061] Specifically, there is a filtering device 2 between the laundry sewage output end of the laundry equipment 1 and the sewage treatment device 3, so that the granular solids in the laundry sewage before flowing into the sewage treatment device 3 are removed first. The sewage filtered by the filtering device 2 passes through the water pump 34 and enters the oxidation treatment device 31. The oxidation gas generated by the oxidation gas generator 32 forms a gas-liquid pressurization and mechanical cutting effect with the filtered sewage in the oxidation treatment device 31, so that the oxidation gas forms countless oxidation gas nanometer microbubbles. Specifically, the sewage electrolysis module 33 has an anode electrolytic cell and a cathode electrolytic cell, and the two electrolytic cells are separated by a semi-permeable membrane. The sewage electrolysis module 33 is connected to the output end of the oxidation treatment device 31, and oxygen can be electrolytically generated inside it, and the oxygen further strengthens the oxidation effect of the oxidation gas nanometer microbubbles output by the oxidation treatment device 31 on the sewage and then outputs to form primary recycled water.

[0062] Refer to Table 2, which is an example of the water quality analysis of the primary recycled water after leaving the sewage treatment device 3.

[0063]

[0064] The primary recycled water leaving the sewage electrolysis module 33 then enters the bubble generating device 4. Please refer to Figure 2B the schematic diagram of the bubble generating device 4 shown. The bubble generating device 4 includes a water tank 43, a hydrogen electrolysis module 42, an electrolysis water pump 44, a bubble water pump 45, and a bubble generator 41. The primary recycled water leaving the sewage treatment device 3 can flow into the water tank 43 of the bubble generating device 4 by gravity or be pumped.

[0065] Specifically, the water tank 43 simultaneously has the functions of storing the recycled water and buffering between the hydrogen electrolysis module 42 and the bubble generator 41. Specifically, the water tank 43 includes a buffer water tank 432 and a main water tank 431. The primary recycled water isolated by the buffer water tank 432 flows into the main water tank 431, passes through the hydrogen electrolysis module 42, and then flows back to the buffer water tank 432 to form the electrolyzed water of the first cycle. The electrolyzed water is transported from the buffer water tank 432 to the bubble generator 41 and then flows back to the main water tank 431 to complete the second cycle. That is to say, the main water tank 431 is connected to the first cycle of the hydrogen electrolysis module 42. Through the operation of the electrolysis water pump 44 at the output end of the hydrogen electrolysis module 42, the sewage in the main water tank 431 is electrolyzed by the hydrogen electrolysis module 42, further increasing the number of alkaline hydroxide ions in the sewage and raising the pH value. The buffer water tank 432 is connected to the output ends of the hydrogen electrolysis module 42 and the electrolysis water pump 44, so that the buffer water tank 432 is followed by the bubble water pump 45 and the bubble generator 41 to form the second cycle. In the second cycle, the main functions of the bubble generator 41 are mixing, gas-liquid pressurization, and mechanical cutting, making the hydrogen nano microbubbles in the liquid phase more delicate and uniform.

[0066] It should be understood that the hydrogen electrolysis module 42 also provides the operation control for the liquid in the water tank 43 of the bubble generating device 4 to gradually pass through the first cycle and the second cycle, gradually turning the circulating liquid into recycled water, and the recycled water meets the washing liquid standard for use in the laundry equipment 1.

[0067] Referring to Table 3, for the laundry equipment 1 using hydrogen nano microbubbles for laundry, according to Figure 1 and Figure 2B One example of the analysis of the quality of the recycled water in the shown process.

[0068]

[0069] The recycled water flows back into the laundry equipment 1 and can be directly used for washing in the laundry equipment 1. The quality range of the recycled water includes a hydrogen bubble diameter below 1000 nm, more than 1 billion nano hydrogen bubbles per milliliter, a pH value of about 10 - 13, an oxidation-reduction potential (ORP) between -500 and -900 mV, a conductivity between 5 - 10 ms / cm, and a temperature between 20 - 70 degrees Celsius, etc.

[0070] Please refer to Figure 3 , Figure 3 For Figure 2ASchematic structural diagram of the oxidation treatment device 31 of the sewage treatment device 3 shown. The oxidation treatment device 31 sequentially includes a sewage inlet end 311, an oxidation gas inlet end 312, a first mixing section 313 for mixing laundry sewage and oxidation gas, a first gas-liquid pressurization module 314 for pressurizing the fluid after gas-liquid mixing, a first cutting section 315 for cutting the pressurized gas-liquid mixed fluid, and an output end. The first cutting section 315 is composed of a plurality of cutters 3150.

[0071] It should be understood that the sewage filtered by the filtering device 2 to remove particulate pollutants carries high-concentration pollutants. Therefore, the oxidation treatment device 31 uses an oxidation gas, such as oxygen or ozone, preferably ozone, to improve the sufficient oxidation power. Through the mixing, gas-liquid pressurization, and mechanical cutting in the oxidation treatment device 31, the oxidation gas can form countless oxidation gas nanobubbles with a nanoscale size. By nano-sizing the oxidation gas, more reaction specific surface areas can be effectively provided, thereby strengthening the decomposition mechanism of pollutants. The concentration of the oxidation gas nanobubbles increases with the increase in the content of sewage pollutants.

[0072] Specifically, please further combine Figure 2A and Figure 3 to show a specific connection method of the oxidation treatment device 31 applied in the sewage treatment system 10. The sewage outlet end of the laundry equipment 1 is connected to the sewage inlet end 311 of the oxidation treatment device 31 through the filtering device 2 and the water pump 34. The sewage inlet end 311 is communicated with the first mixing section 313. The oxidation gas generator 32 is communicated with the first mixing section 313 through the inlet end 312. The first cutting section 315 is connected to the primary recycled water inlet end 411 of the bubble generator 41 through the output end of the oxidation treatment device 31.

[0073] It should be understood that the laundry sewage generated by the laundry equipment 1 is transported to the first mixing section 313 in the oxidation treatment device 31 through the sewage inlet end 311. The oxidation gas generated by the oxidation gas generator 32 is transported to the first mixing section 313 in the oxidation treatment device 31 through the inlet end 312. The oxidation gas and the liquid enter the oxidation treatment device 31 separately without interfering with each other, which improves the working efficiency of the sewage treatment process.

[0074] Further, the oxidation gas includes oxygen or ozone, more preferably ozone. The oxidation gas is introduced into the intake end 312 of the oxidation treatment device 31 at a flow rate of 5 - 30 m / s. The first mixing section 313 is used to mix the oxidation gas and the laundry sewage to generate oxidation gas bubble water. The first gas-liquid pressurization module 314 is used to rotate and pressurize the oxidation gas bubble water and transport the oxidation gas bubble water to the first cutting section 315 for cutting treatment to generate oxidation gas nano microbubble water. It should be noted that the first gas-liquid pressurization module 314 pressurizes the ozone water until the water flow rate is 0.5 - 3.0 m / min, and then the pressurized oxidation gas bubble water can be transported into the first cutting section 315 for cutting treatment, so that the oxidation gas bubble water is converted into oxidation gas nano microbubble water.

[0075] In some possible implementation manners, the oxidation treatment device 31 is generally a columnar body, and the first cutting section 315 has a cutter 3150 with a negative number. Specifically, a specific included angle is formed between the axial direction of the cutter 3150 and the axial direction of the oxidation treatment device 31. The cutter 3150 performs a shear cutting action on the pressurized oxidation gas bubble water, so that the particle size of the oxidation gas nano microbubbles in the formed oxidation gas nano microbubble water is within 1000 nm. It should be understood that compared with ordinary bubbles, the contact area between the oxidation gas nano microbubbles and the sewage is larger, which can accelerate the reaction rate of the oxidation gas with the sewage to improve the treatment efficiency of the sewage.

[0076] It should be noted that the sewage is mixed with, for example, ozone water. During the cutting treatment in the oxidation treatment device 31, there may be a single cutter 3150 in the oxidation treatment device 31. The user controls the flow rate of the sewage, so that the sewage generates a vortex in the oxidation treatment device 31. The vortex rotates along the inner cavity of the oxidation treatment device 31 and collides with the cutter 3150 for cutting, so that the oxidation gas bubbles carried in the sewage are cut into oxidation gas nano microbubbles. Preferably, the type of the cutter 3150 can be various. For example, a plurality of cutters 3150 can be arranged in segments in the oxidation treatment device 31, and the oxidation gas carried by the sewage is gradually divided into micron bubbles after passing through different types of cutters 3150. The specific manner of generating the oxidation gas nano microbubbles in this embodiment is not limited.

[0077] Further explanation Figure 2A and Figure 3, in this embodiment, the laundry wastewater generated by laundry is filtered by the filtering device 2 and then introduced into the sewage inlet end 311 of the oxidation treatment device 31. During the sewage treatment process, the oxidation gas generator 32 continuously generates oxidation gas and inputs the oxidation gas into the intake end 312 of the oxidation treatment device 31. At this time, the oxidation gas and the sewage are mixed in the first mixing section 313 of the oxidation treatment device 31 to form oxidation gas bubble water. The user pressurizes the oxidation gas bubble water through the first gas-liquid pressurization module 314, so that the water flow velocity of the oxidation gas bubble water forms a vortex inside the oxidation treatment device 31 and is cut by the cutter 3150. The cutting treatment makes the oxidation gas bubbles be cut into oxidation gas nanomicrobubbles, and then oxidation gas nanomicrobubble water can be generated.

[0078] It should be noted that the oxidation gas nanomicrobubbles, more preferably ozone nanomicrobubbles, have the ability to sterilize and disinfect. After the ozone nanomicrobubbles are generated, the laundry wastewater can be sterilized and disinfected by consuming the ozone nanomicrobubbles. At the same time, it should be noted that the generated content of the oxidation gas nanomicrobubbles in the oxidation treatment device 31 needs to be greater than the consumed content of the oxidation gas nanomicrobubbles in the sterilization and disinfection, so as to ensure that the pollutants in the laundry wastewater can be completely consumed to complete the sterilization and detoxification. In addition, the particle size of the ozone nanomicrobubbles is within 1000 nm. Compared with ordinary bubbles, the ozone nanomicrobubbles have a larger contact area with the sewage, which can accelerate the oxidation reaction rate of ozone to the sewage and thus improve the sewage treatment efficiency. That is, the oxidation treatment device 31 outputs oxidation gas nanomicrobubble water after oxidizing the laundry wastewater.

[0079] Further, please continue to refer to Figure 2A and Figure 3 , after the oxidation gas nanomicrobubble water is output from the output end of the oxidation treatment device 31, it is directly input into the sewage electrolysis module 33 for electrolysis treatment. Oxygen is generated in the anode tank of the sewage electrolysis module 33. The oxygen strengthens the oxidation treatment effect of the oxidation gas nanomicrobubbles on the laundry wastewater and speeds up the oxidation treatment efficiency, so that the sewage is treated clean and then the primary recycled water is output from the output end of the sewage electrolysis module 33 to improve the treatment effect of the sewage treatment device 3 on the laundry wastewater.

[0080] Specifically, the oxidation gas nanomicrobubble water is introduced into the input end of the sewage electrolysis module 33 at a rate of 0.85 m / min for electrolysis treatment. Specifically, the oxidation gas nanomicrobubble water is electrolyzed based on a preset voltage, a preset current, and a preset electrolyte concentration to obtain primary recycled water; wherein, the preset voltage is 600 volts and the preset current is 15 amperes.

[0081] Please refer to Figure 4 , Figure 4 ForFigure 2B Schematic structural diagram of the bubble generator 41 of the bubble generating device 4 shown. The bubble generator 41 successively includes a primary recycled water inlet end 411, a second mixing section 413 for enhancing the gas-liquid mixing of the fluid, a second gas-liquid pressurization module 414 for pressurizing the fluid after gas-liquid mixing, a second cutting section 415 for cutting the pressurized gas-liquid mixed fluid, and an output end. The second cutting section 415 is composed of a plurality of cutters 4150.

[0082] Different from the structure of the oxidation treatment device 31, the structure of the oxidation treatment device 31 further provides an air inlet end 312 for inputting oxidation gas, which is located before the sewage inlet end 311 to the first mixing section 313, so that the sewage and the oxidation gas meet in this interval and then enter the first mixing section 313. Since the inlet end of the bubble generator 41 comes from the primary recycled water treated by the sewage treatment device 3, there is essentially no need to introduce oxidation gas for further oxidation. On the contrary, since it is necessary to convert the oxidation gas nano microbubble water into hydrogen nano microbubble water, the mechanical cutting by the bubble generator 41 can better meet the requirements of the washing liquid standard.

[0083] Further combined with Figure 2B and Figure 4 to show a possible connection mode of applying the bubble generating device 4 to the sewage treatment system 10. The output end of the hydrogen electrolysis module 42 is successively connected to the primary recycled water inlet end 411 of the bubble generator 41 through an electrolysis water pump 44, a buffer water tank 432, and a bubble water pump 45. The primary recycled water inlet end 411 is communicated with the second mixing section 413; the second mixing section 413 is communicated with the second cutting section 415, and the second cutting section 415 is connected to the input end of the laundry equipment 1 through the output end of the bubble generator 41.

[0084] Specifically, the second mixing section 413 is used to mix hydrogen bubbles and alkaline ion water, or hydrogen bubbles, alkaline ion water and primary recycled water. The second gas-liquid pressurization module 414 is used to rotate and pressurize the water mixed in the second mixing section 413 and transport it to the second cutting section 415 for cutting treatment to make ozone escape, so that the hydrogen nano microbubble water available for laundry can be output from the output end of the bubble generator 41.

[0085] It should be noted that the second gas-liquid pressurization module 414 pressurizes the hydrogen-ozone mixed bubble water until the water flow rate is 0.85 m / min, and then the pressurized hydrogen-ozone mixed bubble water can be transported into the second cutting section 415 for cutting treatment, so that the hydrogen-ozone mixed bubble water is converted into hydrogen nano microbubble water, which is simple and convenient.

[0086] In a possible implementation manner, please combine Figure 2B and Figure 4, the bubble generator 41 is generally a columnar body. The second cutting section 415 has a cutter 4150. The cutter 4150 performs a shear cutting action on the pressurized mixed water so that the particle size of the hydrogen nano microbubbles in the formed hydrogen nano microbubble water is within 1000 nm. It should be understood that compared with ordinary bubbles, the hydrogen nano microbubbles with a particle size of about 1000 nm have a larger contact area with the stains on the clothes, can provide the cleaning ability of the hydrogen nano microbubbles to the clothes, and improve the laundry efficiency.

[0087] Further explanation Figure 2B , in one embodiment of the present invention, the primary recycled water in the water tank 43 is first transported to the hydrogen electrolysis module 42 through the main water tank 431, and then the hydrogen electrolysis module 42 is used to ionize the water to generate hydrogen bubbles and alkaline ion water. Then, the hydrogen bubbles and alkaline ion water are sequentially input into the bubble generator 41 through the electrolysis water pump 44, the buffer water tank 432 and the bubble water pump 45. The bubble generator 41 performs a cutting process on the hydrogen bubbles and alkaline ion water, and hydrogen nano microbubble water that can be used for laundry can be generated. The hydrogen nano microbubble water is output from the output end of the bubble generating device 4 to the laundry device 1 for laundry operations.

[0088] It should be understood that the main component of the primary recycled water is oxidized gas nano microbubble water. The primary recycled water enters the water tank 43, and the primary recycled water, excess oxidized gas, hydrogen bubbles and alkaline ion water generated by the hydrogen electrolysis module 42, etc., can be cut by the bubble generator 41 to generate hydrogen nano microbubble water. At this time, the hydrogen content in the liquid mixture gradually increases, and as the cutting process progresses, the generated hydrogen nano microbubbles gradually squeeze out the residual oxidized gas nano microbubbles, causing the oxidized gas nano microbubbles to gradually dissipate, and finally turning the recycled water into hydrogen nano microbubble water with strong cleaning ability.

[0089] Specifically, during the laundry operation, the hydrogen nano microbubbles will penetrate into the clothing fibers and be adsorbed on the clothing surface. When the hydrogen nano microbubbles burst, the inertial force generated by the burst will cause the stains on the clothes to lose the adsorption force with the clothing surface and desorb. The stains then combine with the bubbles, and through the air flotation effect generated by the hydrogen nano microbubbles, the stains are thus carried away from the clothing surface.

[0090] It can be understood that in the system architecture of multiple laundry devices 1, the amount of laundry sewage generated is multiplied compared to the amount of sewage that can be generated by a household washing machine or a single washing machine. Therefore, how to plan and treat the sewage generated by multiple laundry devices 1, especially including the laundry factory 100, means that water resources can be saved more effectively.

[0091] Please combine Figure 1 and refer toFigure 5 , the first embodiment of the present invention provides a laundry factory 100 having a sewage treatment system 10, and the sewage treatment system 10 as shown in the figure is referred to. Specifically, the laundry factory 100 includes a plurality of laundry devices 1, and the inlet end of each laundry device 1 is connected to the output end of the sewage treatment system 10, so that the laundry device 1 uses the recycled water of the sewage treatment system 10 for the main washing operation.

[0092] Specifically, please refer to Figure 2A , the laundry factory 100 includes a sewage treatment device 3. The sewage treatment device 3 includes an oxidation treatment device 31, an oxidation gas generator 32 and a sewage electrolysis module 33; the inlet end of the oxidation treatment device 31 is connected to the output end of the laundry sewage generated by the laundry device 1. The oxidation gas generator 32 generates oxidation gas and transports it to the oxidation treatment device 31, so that the oxidation gas and the laundry sewage are oxidatively decomposed in the oxidation treatment device 31, and the output end of the oxidation treatment device 31 is connected to the sewage electrolysis module 33. Through electrolysis, the oxidation gas nanomicrobubble water generated by the output of the oxidation treatment device 31 is formed into primary recycled water;

[0093] Specifically, please refer to Figure 2B , the laundry factory 100 includes a bubble generating device 4. The bubble generating device 4 includes a water tank 43 connected to the output end of the sewage electrolysis module 33, a hydrogen electrolysis module 42 connected to the water tank 43, and a bubble generator 41 connected to the hydrogen electrolysis module 42; after the primary recycled water flows into the water tank 43, it passes through the hydrogen electrolysis module 42 and then returns to the water tank 43 to form a first cycle. The hydrogen electrolysis module 42 electrolyzes the primary recycled water to generate hydrogen bubbles and alkaline ion water, which return to the water tank 43 to form the electrolyzed water of the first cycle, and then are transported to the bubble generator 41, and then return to the water tank 43 to form a second cycle. The bubble generator 41 cuts the electrolyzed primary recycled water, hydrogen bubbles and alkaline ion water to form recycled water, and the recycled water generated in the second cycle is provided to the laundry device 1 for recycling.

[0094] Understandably, when the laundry factory 100 starts to operate and work, the laundry to be washed is first placed in a plurality of laundry devices 1, and the laundry factory 100 is started. After the external water is first introduced into the bubble generating device 4, the bubble generating device 4 of the laundry factory 100 converts the external water into hydrogen nano-microbubble water for laundry, and further transports the hydrogen nano-microbubble water to the laundry device 1 to wash the laundry to be washed. The laundry sewage generated after washing is output from the output end of the laundry device 1 to the input end of the sewage treatment device 3. After the laundry sewage is oxidized by the oxidation treatment device 31 in the sewage treatment device 3, primary recycled water is generated by electrolysis, and the primary recycled water is further transported back into the bubble generating device 4 and converted into recycled water that can be used for laundry by the bubble generating device 4 to complete the treatment and recycling of the laundry sewage. By providing the sewage treatment device 3 and the bubble generating device 4, the laundry sewage generated by the plurality of laundry devices 1 is recycled, solving the problem that it is difficult to recycle and treat laundry sewage in the prior art and solving the problem of water resource waste.

[0095] In some other embodiments, multiple laundry modes can be adopted in the laundry factory, such as a pre-washing mode, a main-washing mode, a rinsing mode, etc. That is, the laundry factory can select different laundry modes and washing water according to different needs of users.

[0096] Regarding the above laundry modes, please refer to Figure 1 and Figure 6 , the second embodiment of the present invention provides a laundry factory 200 having a sewage treatment system 10. The laundry factory 200 includes a plurality of laundry devices 201, and the inflow end of each laundry device 201 is connected to the output end of the sewage treatment system 10, so that the pre-washing or rinsing of the laundry device 201 uses the primary recycled water of the sewage treatment system 10 for washing operations, and the main-washing of the laundry device 201 uses the recycled water of the sewage treatment system 10 for washing operations.

[0097] Specifically, please refer to Figure 2A together. The laundry factory 200 further includes a sewage treatment device 203. The sewage treatment device 203 includes an oxidation treatment device 31, an oxidation gas generator 32 and a sewage electrolysis module 33; the inflow end of the oxidation treatment device 31 is connected to the output end of the laundry sewage generated by the laundry device 201. The oxidation gas generator 32 generates oxidation gas and transports it to the oxidation treatment device 31, so that the oxidation gas and the laundry sewage are oxidized and decomposed in the oxidation treatment device 31, and the output end of the oxidation treatment device 31 is connected to the sewage electrolysis module 33. By electrolysis, the oxidation gas nano-microbubble water output by the oxidation treatment device 31 is formed into primary recycled water.

[0098] Further, the laundry factory 200 further includes a first connection pipeline 205 connecting the sewage treatment device 203 and the laundry equipment 201. When the laundry equipment 201 performs pre-washing or rinsing, the primary recycled water generated by the sewage treatment device 203 is used to supply water to the laundry equipment 201. It should be understood that when there are fewer clothes in the plural laundry equipment 201 and the clothes only need to perform the pre-washing or rinsing mode, at this time, the primary recycled water can directly enter the laundry equipment 201 through the first connection pipeline 205, and the primary recycled water then washes the clothes in the laundry equipment 201 to complete the pre-washing or rinsing of the clothes.

[0099] Specifically, please refer to Figure 2B , the laundry factory 200 includes a bubble generating device 204, which includes a water tank 43 connected to the output end of the sewage electrolysis module 33, a hydrogen electrolysis module 42 connected to the water tank 43, and a bubble generator 41 connected to the hydrogen electrolysis module 42; after the primary recycled water flows into the water tank 43, it passes through the hydrogen electrolysis module 42 and then returns to the water tank 43 to form a first cycle. The hydrogen electrolysis module 42 electrolyzes the primary recycled water to generate hydrogen bubbles and alkaline ion water, and the electrolyzed water that returns to the water tank 43 to form a first cycle is then transported to the bubble generator 41, and then returns to the water tank 43 to form a second cycle. The bubble generator 41 cuts the electrolyzed primary recycled water, hydrogen bubbles and alkaline ion water to form recycled water.

[0100] Further, the laundry factory 200 further includes a first connection pipeline 205 connecting the bubble generating device 204 and the laundry equipment 201. When the laundry equipment 201 performs main washing, the recycled water generated by the bubble generating device 204 is used to supply water to the laundry equipment 201. It should be understood that when the user needs to perform the main washing mode, at this time, the primary recycled water needs to enter the bubble generating device 204. Specifically, after the primary recycled water flows into the water tank 43, it is electrolyzed by the hydrogen electrolysis module 42 to generate hydrogen bubbles and alkaline ion water, and the electrolyzed water that returns to the water tank 43 to form a first cycle is then transported to the bubble generator 41, and then returns to the water tank 43 to form a second cycle. The bubble generator 41 cuts the electrolyzed primary recycled water, hydrogen bubbles and alkaline ion water to form recycled water that can be used for main washing of clothes, and then the recycled water directly enters the laundry equipment 201 through the first connection pipeline 205, and the recycled water then washes the clothes in the laundry equipment 201 to complete the main washing of the clothes.

[0101] Please continue to refer to Figure 6 , in this embodiment, the sewage treatment system 10 includes an additionally provided sewage treatment device 213 and a second connection pipeline 214 connecting the additionally provided sewage treatment device 213 and the laundry equipment 201. When the laundry equipment 201 performs pre-washing or rinsing, the primary recycled water generated by the sewage treatment device 203 directly supplies water to the laundry equipment 201.

[0102] Specifically, the laundry device 201 includes a first input end 2011, a first output end 2012, a second input end 2013, and a second output end 2014; the first output end 2012 of the laundry device 201 is connected to the input end of the sewage treatment device 203 through a first connection pipeline 205, the output end of the sewage treatment device 203 is connected to the input end of the bubble generating device 204, and the output end of the bubble generating device 204 is connected to the first input end 2011 of the laundry device 201; the second output end 2014 of the laundry device 201 is connected to the input end of another sewage treatment device 213, and the output end of the another sewage treatment device 213 is connected to the second input end 2013 of the laundry device 201.

[0103] As a possible implementation, when there are a large number of clothes in the plural laundry devices 201 and the clothes only need to perform a pre-washing or rinsing mode, at this time, the laundry sewage can be transported into the another sewage treatment device 213, and through the treatment of the sewage treatment device 203, primary recycled water is generated. The primary recycled water can directly enter the laundry device 201 through the second connection pipeline 214, and the primary recycled water is used to wash the clothes in the laundry device 201 to complete the pre-washing or rinsing of the clothes.

[0104] As another possible implementation, when there are a large number of clothes in the plural laundry devices 201 and the clothes only need to perform a pre-washing or rinsing mode, at this time, the laundry sewage can be transported into the sewage treatment device 203 and the another sewage treatment device 213, and through the treatment of the sewage treatment device 203 and the another sewage treatment device 213, primary recycled water can be generated respectively. The primary recycled water enters the laundry device 201 through the first connection pipeline 205 and the second connection pipeline 214 respectively, and then is used to wash the clothes in the laundry device 201 to complete the pre-washing or rinsing of the clothes. It should be understood that the sewage treatment device 203 and the another sewage treatment device 213 perform oxidation treatment and cutting treatment simultaneously to generate sufficient primary recycled water to cope with a large number of clothes to be washed.

[0105] Furthermore, there is a first filtering device 202 between the laundry device 201 and the inflow end of the sewage treatment device 203. It should be understood that the sewage generated by the laundry device 201 may carry large-particle solid dirt, and the solid dirt can be filtered through the first filtering device 202 to avoid large-particle solid dirt from entering the sewage treatment device 203 and causing problems such as dirt deposition or blockage at the input port of the sewage treatment device 203.

[0106] Further, a second filtering device 212 is provided between the laundry device 201 and the inlet end of a separately provided sewage treatment device 213. It should be understood that the sewage generated by the laundry device 201 may carry solid dirt with large particle sizes. The solid dirt can be filtered through the second filtering device 212 to prevent the solid dirt with large particle sizes from entering the separately provided sewage treatment device 213 and causing problems such as dirt deposition or blockage at the input port of the separately provided sewage treatment device 213.

[0107] Please refer to Figure 5 and Figure 7 , the bubble generating device 4 further includes a steam generating device 5, a drying device 6, and a heating pipe 7 that are connected in sequence. The heating pipe 7 is connected to the bubble generating device 4; the steam generating device 5 is used to generate steam and dry the clothes in the drying device 6, and the dried steam passes through the heating pipe 7 to heat the water in the bubble generating device 4.

[0108] It should be understood that after the user washes the clothes with the laundry device 1, the clothes are usually moved into the drying device 6, such as inside a dryer or a pressing machine. The steam generating device 5 is used to generate steam and dry the clothes placed inside the dryer or the pressing machine. The exhausted steam after drying can be directly conveyed through the heating pipe 7 to the water tank 43 in the bubble generating device 4 to heat the water in the water tank 43. During the process of reducing the cost of the laundry factory 100, the energy consumption generated by drying the clothes is further reduced.

[0109] The above has introduced in detail a laundry factory with a sewage treatment system disclosed in the embodiments of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention. Any modifications, equivalent replacements, and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
