Description

Technical Field

[0001] This invention belongs to the field of reactor design, specifically relating to a multifunctional, scalable, modular reaction vessel and method for treating wastewater from shopping malls. Background Technology

[0002] Currently, with the development of the social economy, more and more large shopping malls and shopping centers are emerging in cities. While these malls and shopping centers meet people's consumption needs in shopping, dining, leisure and entertainment, they also bring environmental pollution problems. Shopping mall wastewater mainly comes from restrooms, toilets, restaurants, and office areas. Its composition is complex, containing large amounts of organic matter, suspended solids, and oily substances. The organic matter in the wastewater is extremely unstable and easily decomposes, producing foul odors. Furthermore, the oily substances in the wastewater can easily clog drainage pipes, affecting their flow capacity. Therefore, shopping mall wastewater must be treated to meet national standards and regulations before being discharged into the city's pipe network. However, many reactors in China, especially those designed for processes with smaller treatment volumes, lack variable-volume reaction vessels. Such variable-volume reaction vessels should be able to dynamically adjust according to the reactor's installation environment. Therefore, designing such a variable-volume reactor has significant implications for the current domestic reactor market. Traditional fixed-volume reactors typically suffer from difficulties in disassembly and transportation, and their external dimensions do not match the actual site conditions. Therefore, most reactors have certain shortcomings when put on the market. Summary of the Invention

[0003] The purpose of this invention is to overcome the deficiencies in the prior art and to provide a multifunctional, scalable, modular reaction vessel and method for treating wastewater from shopping malls.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] In a first aspect, the present invention provides a multifunctional, scalable, modular reaction vessel for treating wastewater from shopping malls, comprising a first main reactor, a second main reactor, and a secondary reactor;

[0006] The first and second main reactors are slidably connected by a rack and pinion guide, with connection ports on their outer sides. A gear motor, providing power, is externally connected to the rack and pinion guide, its axis parallel to the axes of the first and second main reactors. Sliding between the rack and pinion guide controls the horizontal distance between them. The auxiliary reactor is a cylindrical structure without lids on both sides, located between the first and second main reactors. A single piece of first expandable inert membrane is circumferentially sealed to the left port of the auxiliary reactor, with the other end of the first expandable inert membrane circumferentially sealed to the inner wall of the first main reactor. A single piece of second expandable inert membrane is circumferentially sealed to the right port of the auxiliary reactor, with the other end of the second expandable inert membrane circumferentially sealed to the inner wall of the second main reactor. Both the first and second expandable inert membranes are axially expandable and contractable. After wastewater enters the reaction vessel through the connection ports, it can only flow within the channel formed by the first main reactor, the first expandable inert membrane, the auxiliary reactor, the second expandable inert membrane, and the second main reactor.

[0007] Preferably, the inner walls of both the first and second main reactors are provided with an inwardly recessed ring of mounting points along a certain cross-section. The first and second stretchable inert membranes are respectively engaged and sealed with the first and second main reactors through the mounting points.

[0008] Furthermore, the groove formed by the mounting point is covered with an HCR 3100 type inert elastic rubber coating.

[0009] Preferably, the geared motor is controlled by a networked intelligent computer, which can remotely control its switching or speed through a numerical control program.

[0010] Preferably, the rack guide rail has four rails, which are located in pairs on the outer side walls of the first main reactor and the second main reactor.

[0011] Preferably, both the first and second main reactors are made of Q235A high-performance carbon structural steel.

[0012] Preferably, the first and second stretchable inert membranes can be stretched by at least 400%-500%.

[0013] Preferably, the first and second stretchable inert films are TPU hot melt silicone films.

[0014] Preferably, the first main reactor and the second main reactor have the same size and structure, and the auxiliary reactor is smaller than the first main reactor and the second main reactor and can be partially located in the inner cavity of both.

[0015] Secondly, the present invention provides a method for using the multifunctional, scalable, modular reaction vessel for treating wastewater in shopping malls as described in any of the first aspects, as follows:

[0016] When the amount of wastewater to be treated increases, the first main reactor and the second main reactor slide outward relative to each other along the rack guide rail via a gear motor, and the first and second stretchable inert membranes are axially stretched, thereby increasing the channel volume.

[0017] When the amount of wastewater to be treated decreases or the floor space is limited, the first and second main reactors slide inward relative to each other along the rack guide rail via a gear motor, reducing the axial stretch of the first and second stretchable inert membranes and decreasing the channel volume.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1) This invention features simple operation, convenient installation, low material costs, easy disassembly and transportation, compact structure, concise process, small footprint, convenient expansion and upgrading, high degree of automation, and simple operation and maintenance. It can also be moved anytime and anywhere, allowing direct transport to the target location for large-scale treatment without secondary construction. 2) This invention is widely applicable to domestic sewage from residential communities, office buildings, shopping malls, hotels, restaurants, government offices, schools, hospitals, ship docks, and farms, as well as similar industrial organic wastewater (organic wastewater from textile, brewing, leather, food, and chemical industries). 3) This invention allows for dynamic adjustment of the reaction vessel's size based on the actual wastewater volume and the available space. Its modular design allows it to adapt to various reaction environments, and more reaction vessels can be assembled and connected to suit different needs based on the size of the shopping mall and the wastewater treatment capacity. Attached Figure Description

[0020] Figure 1 This is a structural schematic diagram of a multifunctional, scalable, modular reaction vessel for treating wastewater from shopping malls, where (a) is a front view, (b) is a side view, and (c) is a top view.

[0021] In the figure: First main reactor 11, second main reactor 12, rack and pinion guide rail 2, mounting point 3, connection port 4, first stretchable inert membrane 51, second stretchable inert membrane 52, auxiliary reactor 6, gear motor 7. Detailed Implementation

[0022] The present invention will be further described and illustrated below with reference to the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention can be combined accordingly, provided that there is no mutual conflict.

[0023] like Figure 1 As shown, this invention provides a multifunctional, expandable, modular reaction vessel for treating wastewater in shopping malls. The reaction vessel mainly includes a first main reactor 11, a second main reactor 12, and a secondary reactor 6. Specifically, the first main reactor 11 and the second main reactor 12 are slidably connected via a rack and pinion guide rail 2, and each of the first main reactor 11 and the second main reactor 12 has a connection port 4 on its outer side.

[0024] In practical use, this connector can be connected to other devices, and its shape can be changed to accommodate various reaction vessels. That is, the connector 4 can be designed in different shapes according to actual conditions, and it can be determined whether the concavity or convexity of the connector needs to be changed to facilitate connection to other reaction vessels. The first main reactor 11 and the second main reactor 12 are preferably made of Q235A high-performance carbon structural steel.

[0025] In the reaction vessel of this invention, a rack and pinion guide 2 is externally connected to a geared motor 7 for providing power. Its axis is parallel to the axes of the first main reactor 11 and the second main reactor 12, and the horizontal distance between the first main reactor 11 and the second main reactor 12 can be controlled by sliding. The auxiliary reactor 6 is a cylindrical structure without lids on both sides, located between the first main reactor 11 and the second main reactor 12.

[0026] In this embodiment, the first main reactor 11 and the second main reactor 12 have the same size and structure, while the auxiliary reactor 6 is smaller than the first main reactor 11 and the second main reactor 12 and can be partially located within the cavities of both. The outer shells of the first main reactor 11 and the second main reactor 12 can be adjusted according to actual needs, and the shape of the connection port 4 and the size and style of the expandable inert membrane will change with the outer shell of the main reactor.

[0027] In the reaction vessel of this invention, a single piece of first expandable inert membrane 51 is circumferentially sealed to the left port of the auxiliary reactor 6, and the other end of the first expandable inert membrane 51 is circumferentially sealed to the inner wall of the first main reactor 11. A single piece of second expandable inert membrane 52 is circumferentially sealed to the right port of the auxiliary reactor 6, and the other end of the second expandable inert membrane 52 is circumferentially sealed to the inner wall of the second main reactor 12. Both the first expandable inert membrane 51 and the second expandable inert membrane 52 can expand and contract axially. After wastewater enters the reaction vessel through the connection port 4, it can only flow within the channel formed by the first main reactor 11, the first expandable inert membrane 51, the auxiliary reactor 6, the second expandable inert membrane 52, and the second main reactor 12.

[0028] In practical use, the stretchable inert membrane can prevent contamination between reactor gaps. Made of inert materials, it will not react with the liquid or microorganisms inside the reaction vessel, and its elasticity will not undergo inelastic deformation due to stretching or compression, meaning it will not be affected by the operation of the gear motor-rack and pinion guide unit. In this embodiment, the stretchable inert membrane is a TPU hot-melt silicone membrane capable of stretching 400%-500% and possessing good resilience. The membrane thickness can be adjusted according to the selected reactor volume. During device operation, the first main reactor 11 and the second main reactor 12 can adjust their distance via the gear motor 7 and the rack and pinion guide 2 to achieve the purpose of adjusting the reaction vessel volume (i.e., channel volume). Furthermore, due to the design of the first stretchable inert membrane 51 and the second stretchable inert membrane 52, it is not necessary to pause the reaction for adjustment when changing the reactor volume.

[0029] In practical use, both the first main reactor 11 and the second main reactor 12 have an inwardly recessed ring of mounting points 3 along a certain cross-section on their inner walls. The first stretchable inert membrane 51 and the second stretchable inert membrane 52 are respectively connected to the first main reactor 11 and the second main reactor 12 by engaging and sealing through the mounting points 3. The mounting points facilitate the mounting or disassembly of the entire reactor. To prevent sewage from seeping out through the gap between the stretchable membrane mounting points and the embedded interconnected auxiliary reactor, a coating of HCR 3100 type inert elastic rubber with high tear resistance can be applied to the groove formed by the mounting points 3.

[0030] In practical use, the gear motor 7 is controlled by a networked intelligent computer, allowing remote control of its operation, such as switching or speed, via a numerical control program. In this embodiment, four rack and pinion guides 2 are provided, located in pairs on the outer sides of the opposite sidewalls of the first main reactor 11 and the second main reactor 12. By having two sets of gear motor-rack and pinion guide units on each side of the outer side of the reaction vessel, they can mutually restrain each other to increase stability during sliding. The gears in the gear motor-rack and pinion guide units use large-module gears to prevent slippage between gears during the expansion and contraction of the reaction vessel. Furthermore, since the rack and pinion guides are located outside the reaction vessel, changes in the vessel volume will not hinder the expansion and contraction of the inert membrane within the reaction vessel's jacket.

[0031] When using the aforementioned multifunctional, expandable, modular reaction vessel for shopping mall wastewater treatment, the volume of the reaction vessel (i.e., the channel volume) can be reasonably adjusted according to the specific required floor space, as follows:

[0032] When the amount of wastewater to be treated increases, the first main reactor 11 and the second main reactor 12 slide outward relative to each other along the rack guide rail 2 via the gear motor 7, and the first stretchable inert membrane 51 and the second stretchable inert membrane 52 are axially stretched, increasing the channel volume.

[0033] When the amount of wastewater to be treated decreases or the floor space is limited, the first main reactor 11 and the second main reactor 12 slide inward relative to each other along the rack guide rail 2 via the gear motor 7, thereby reducing the axial stretching of the first stretchable inert membrane 51 and the second stretchable inert membrane 52 and reducing the channel volume.

[0034] The expandable inert membrane in this multifunctional, expandable, modular reaction vessel for shopping mall wastewater treatment can be replaced with a more suitable expandable inert material to facilitate reactor operation, depending on the reaction conditions within the vessel and the external chemical and biological environment. The geared motor-industrial rack and pinion system is controlled by a networked intelligent computer. Its digital monitoring program monitors the reactor's throughput in real time and controls the system accordingly. Simultaneously, by inputting floor space parameters into the digital program, it can provide the optimal reaction vessel volume for reference.

[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all technical solutions obtained through equivalent substitution or transformation fall within the protection scope of the present invention.
