Description

[Technical Field]

[0001] This utility model relates to the field of sugarcane deep processing technology, specifically to a sugarcane plant water filtration and purification device. [Background Technology]

[0002] Sugarcane, a crop widely cultivated in tropical and subtropical regions, not only plays a vital role in the food industry but also demonstrates diverse applications in energy, medicine, agriculture, and other fields. Improvements in cultivation techniques and innovations in processing methods are continuously expanding the utilization value of sugarcane. Traditionally, sugarcane is mainly used for sugar production and fresh consumption, but with technological advancements, its applications in biofuels and environmentally friendly materials are gradually gaining attention. For example, sugarcane bagasse is used to manufacture environmentally friendly pellets and cultivate edible fungi, while sugarcane leaves can be used as animal feed or for producing paper and fiberboard. Furthermore, the medicinal value of sugarcane cannot be ignored; the various amino acids and trace elements in its sap have certain tonic effects. In terms of cultivation, selecting suitable varieties and employing scientific management methods are crucial for improving sugarcane yield and quality. With the in-depth exploration of sugarcane resources, its potential economic and ecological value will be further released, providing new impetus for sustainable development.

[0003] Sugarcane plant water is an innovative natural beverage successfully developed by our company in collaboration with university research teams after years of scientific research. It retains the natural nutrients and unique flavor of sugarcane to the greatest extent possible. Unlike traditional beverages, it is naturally healthy, with a refreshing and smooth taste and a sweet aftertaste. Its launch not only fills a gap in the domestic sugarcane plant water beverage market but also provides consumers with a brand-new healthy beverage option, satisfying modern people's pursuit of healthy and natural drinks. As a forward-looking product, the development of sugarcane plant water reflects our company's innovative concept of in-depth development and comprehensive utilization of sugarcane resources, and also demonstrates our determination and strength in promoting the sugarcane industry towards high-value and diversified development.

[0004] Because sugarcane plant water is a new product for our company, it cannot be directly bottled after extraction and preparation; it requires a series of processing steps. Since this product is a first for our company, existing technologies lack specialized processes and equipment for large-scale purification of sugarcane plant water. Current general-purpose equipment suffers from the problem of traditional plant water treatment using decentralized equipment combinations, lacking coordinated control between processes, resulting in high loss rates of effective components. Conventional RO systems lack effective and convenient cleaning functions; the polysaccharides and colloidal substances in sugarcane plant water cause membrane flux to drop to below 50% of its initial value after a period of continuous operation, such as 48 hours, requiring frequent shutdowns to replace membrane modules. Therefore, a new production device is needed to solve the problem of sugarcane plant water purification. [Utility Model Content]

[0005] The purpose of this invention is to address the lack of a dedicated sugarcane plant water purification device in the existing technology, and to provide a sugarcane plant water filtration and purification device that has a high purification effect, while effectively preserving the characteristic flavor substances of sugarcane plant water, extending the RO membrane life by 3-5 times. It solves the technical problems of flavor component loss, irreversible membrane fouling, and difficulty in continuous production in traditional processes, and is suitable for the industrial continuous production of sugarcane plant water.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sugarcane plant water filtration and purification device, comprising the following components connected sequentially along the material flow direction:

[0008] The raw water tank has its inlet connected to the feed pipe;

[0009] The activated carbon treatment unit is connected to the raw water tank outlet via a second pumped pipeline.

[0010] The RO reverse osmosis treatment unit has its inlet connected to the outlet of the activated carbon treatment unit via a third pumped pipe, and its product water outlet connected to the inlet of the pure water tank via a first connecting pipe.

[0011] The outlet of the pure water tank is connected to the inlet of the ozone tower treatment unit via a fourth pump-equipped pipeline.

[0012] The outlet of the ozone tower treatment unit is connected to the inlet of the high-temperature sterilization treatment unit via a fifth pump-equipped pipeline.

[0013] The outlet of the high-temperature sterilization unit is connected to a liquid outlet pipe;

[0014] Furthermore, the RO reverse osmosis treatment unit is further optimized by including a concentrate outlet at its inlet and a reverse cleaning system, which comprises a hot water unit, an acid washing unit, and an alkaline washing unit.

[0015] The hot water unit is connected to the RO reverse osmosis treatment unit's water outlet via a seventh pipe;

[0016] The acid washing unit is connected to the RO reverse osmosis treatment unit's product water outlet via an eighth pipe;

[0017] The alkaline washing unit is connected to the RO reverse osmosis treatment unit's product water outlet via the ninth pipe;

[0018] The cleaning water from the reverse cleaning system is discharged through the concentrate outlet.

[0019] Further optimizations include a switching valve assembly, wherein the switching valve is located between the water outlet and the first connecting pipe, and is also connected to the seventh, eighth and ninth pipes.

[0020] Further optimized, the switching valve assembly is a five-way valve.

[0021] Furthermore, the RO reverse osmosis treatment unit adopts a spiral wound composite membrane with a pore size of 0.1-0.5 nm and an operating pressure of 1.5-2.5 MPa.

[0022] In a further optimized configuration, the high-temperature sterilization unit includes a plate heat exchanger and a holding tube connected in series. The plate heat exchanger heats the material to 90-95°C, and the holding tube is 10-15 meters long with a residence time of 30-60 seconds.

[0023] Further optimization involves installing a security filter between the activated carbon treatment unit and the RO reverse osmosis treatment unit, with a filtration accuracy of 5-10μm.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] 1. This utility model is designed specifically for the characteristics of sugarcane plant water. By sequentially arranging a raw water tank, activated carbon treatment unit, RO reverse osmosis treatment unit, pure water tank, ozone tower treatment unit, and high-temperature sterilization unit along the material flow direction, it achieves deep purification of sugarcane plant water. Activated carbon treatment effectively adsorbs organic matter and odors, RO reverse osmosis precisely filters impurities and harmful substances, and the ozone tower and high-temperature sterilization ensure thorough sterilization, guaranteeing the purity and safety of the sugarcane plant water and meeting the market requirements for high-quality beverages.

[0026] The raw water tank and activated carbon unit form a gradient pretreatment system that can remove more than 95% of macromolecular colloids. The RO unit effectively removes impurities with a molecular weight >200 Da, and the turbidity of the produced water is ≤0.1 NTU. The ozone-high temperature coupled sterilization achieves a sterilization rate >6 log and a characteristic flavor retention rate ≥85% through the synergistic effect of low temperature oxidation and short-time high temperature.

[0027] 2. Innovative Reverse Cleaning System: The specially designed reverse cleaning system includes a hot water unit, an acid washing unit, and an alkaline washing unit. Cleaning water is discharged through the concentrate outlet, achieving highly efficient cleaning of the RO reverse osmosis treatment unit. The combination of acid washing, alkaline washing, and hot water rinsing effectively removes contaminants from the membrane surface, extends membrane lifespan, reduces equipment operating costs, and ensures stable product quality.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Example 1

[0035] See Figure 1 , Figure 2 A sugarcane plant water filtration and purification device, comprising the following components connected sequentially along the material flow direction:

[0036] Raw water tank 12, whose inlet is connected to feed pipe 11;

[0037] The activated carbon treatment unit 13 is connected to the outlet of the raw water tank via a second pumped pipe 121;

[0038] The RO reverse osmosis treatment unit 17 has its inlet connected to the outlet of the activated carbon treatment unit via a third pump-equipped pipe 131, and its product water outlet connected to the inlet of the pure water tank 18 via a first connecting pipe 171.

[0039] The outlet of the pure water tank 18 is connected to the inlet of the ozone tower treatment unit 19 via a fourth pumped pipe 181.

[0040] The outlet of the ozone tower treatment unit 19 is connected to the inlet of the high-temperature sterilization treatment unit 20 via a fifth pumped pipe 191.

[0041] The high-temperature sterilization unit 20 has an outlet connected to the liquid outlet pipe 201.

[0042] In an even better solution, a security filter is provided between the activated carbon treatment unit 13 and the RO reverse osmosis treatment unit 17. The filter has a filtration accuracy of 5-10μm, which can effectively intercept small particles and suspended solids that may remain after activated carbon treatment, prevent them from entering the RO reverse osmosis treatment unit, protect the RO membrane, and improve the overall operating efficiency and stability of the system.

[0043] In another preferred embodiment, the RO reverse osmosis treatment unit 17 uses a spiral wound composite membrane with a pore size of 0.1-0.5 nm and an operating pressure of 1.5-2.5 MPa. The high-temperature sterilization treatment unit 20 includes a plate heat exchanger and a holding tube connected in series. The plate heat exchanger heats the material to 90-95°C, and the holding tube is 10-15 meters long with a residence time of 30-60 seconds. A security filter with a filtration accuracy of 5-10 μm is provided between the activated carbon treatment unit 13 and the RO reverse osmosis treatment unit 17.

[0044] In practice, the sugarcane plant water raw solution enters the raw water tank 12 through the feed pipe 11. After temporary storage, it flows sequentially into the activated carbon treatment unit 13, where the activated carbon's adsorption properties remove organic matter and odors. It then enters the RO reverse osmosis treatment unit 17, where a spiral wound composite membrane (membrane pore size 0.1-0.5nm, operating pressure 1.5-2.5MPa) traps and removes most of the dissolved salts, small molecule organic matter, bacteria, viruses, and other impurities, resulting in high-purity sugarcane plant water. The purified water after RO reverse osmosis treatment flows into the pure water tank 18 for temporary storage, and is then transported to the ozone tower treatment unit 19 via the fourth pump pipeline 181. The strong oxidizing properties of ozone kill residual bacteria, viruses, and other microorganisms, decompose organic pollutants, and further improve water quality. After ozone treatment, the sugarcane plant water enters the high-temperature sterilization unit 20, where the material is heated to 90-95°C through a plate heat exchanger and held in a 10-15 meter long holding tube for 30-60 seconds to completely kill residual microorganisms and ensure that the product meets commercial sterility standards.

[0045] In addition, to achieve efficient cleaning of the RO reverse osmosis treatment unit 17, this device also includes a reverse cleaning system with a concentrate outlet at its inlet, a hot water unit 14, an acid washing unit 15, and an alkaline washing unit 16. The hot water unit 14 is connected to the RO reverse osmosis treatment unit 17's product water outlet through a seventh pipe 141; the acid washing unit 15 is connected to the RO reverse osmosis treatment unit 17's product water outlet through an eighth pipe 151; and the alkaline washing unit 16 is connected to the RO reverse osmosis treatment unit 17's product water outlet through a ninth pipe 161. The cleaning water from the reverse cleaning system is discharged through the concentrate outlet.

[0046] The reverse cleaning system also includes a switching valve assembly 21, which is located between the water outlet and the first connecting pipe 171, and is also connected to the seventh pipe 141, the eighth pipe 151 and the ninth pipe 161.

[0047] In practice, different cleaning modes are switched through the switching valve group 21 (five-way valve): During normal operation, water flows through the product water port and the first connecting pipe 171 into the subsequent treatment unit; when cleaning is required, the switching valve group connects the product water port to the hot water unit, acid washing unit, and alkaline washing unit respectively, so that the cleaning solution flows back into the RO reverse osmosis treatment unit to complete the acid washing, alkaline washing or hot water rinsing operation, remove pollutants from the membrane surface, and extend the service life of the membrane.

[0048] In a preferred embodiment, the five-way valve can also be an electrically controlled valve, installed between the product water inlet and the first connecting pipe, and simultaneously connected to the hot water unit, acid washing unit, and alkaline washing unit. Its control terminal is connected to a PLC controller, which automatically switches cleaning modes according to preset conditions (such as time cycles, flow meter signals, etc.) to achieve automated control of acid washing, alkaline washing, and hot water rinsing. Under normal operating conditions, the solenoid valve connects the product water inlet to the first connecting pipe, allowing the RO reverse osmosis treated water to flow to subsequent treatment units. When cleaning is required, the PLC controller issues a command, and the solenoid valve automatically switches to the corresponding cleaning mode, connecting the product water inlet to the acid washing unit, alkaline washing unit, or hot water unit respectively, causing the cleaning solution to flow back into the RO reverse osmosis treatment unit. After the cleaning operation is completed, the waste liquid is discharged through the concentrate outlet.

[0049] This automated cleaning control method not only improves the accuracy and reliability of the cleaning process and reduces errors and labor intensity caused by manual operation, but also allows for flexible adjustment of the cleaning cycle and method according to the actual operating conditions of the equipment and water quality, ensuring that the equipment is always in optimal operating condition, thereby further improving the operating efficiency of the equipment and the quality of the products.

[0050] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
