Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a rapid industrial wastewater treatment device based on ultraviolet sterilization. Background Technology

[0002] Ultraviolet (UV) disinfection technology is a physical disinfection method that emits UV light of a specific wavelength to kill microorganisms instantly, thus preventing them from reproducing. UV disinfection has significant advantages such as no secondary pollution, no disinfection byproducts, no alteration of the chemical properties of water, and short action time.

[0003] Existing UV-based industrial wastewater treatment equipment typically includes an established disinfection channel with multiple UV lamp modules arranged in parallel within it, forming a disinfection array. Wastewater to be treated flows into the disinfection channel from the inlet and passes through the gaps between the lamp modules. During this process, the wastewater receives a sufficient dose of UV radiation to achieve sterilization. However, during use, existing UV-based rapid industrial wastewater treatment equipment faces challenges. Due to the complex composition of industrial wastewater, even after pretreatment, some grease, suspended solids, and biological slime still remain. These substances easily adhere and deposit on the outer wall of the quartz sleeve supporting the UV lamps, forming a dense layer of dirt. This dirt layer severely blocks and attenuates the penetration of UV rays, resulting in a significant decrease in the actual radiation intensity. Existing equipment often relies on periodic shutdowns for manual cleaning or using electrical equipment to drive cleaning components such as cleaning brushes.

[0004] Existing industrial wastewater rapid treatment equipment based on ultraviolet sterilization uses electrical equipment to drive cleaning components such as cleaning brushes and sponges to clean the outer wall of the quartz sleeve of the ultraviolet lamp tube. However, the cleaning components are easily worn, which greatly reduces the cleaning effect. Furthermore, dirt and grime can easily accumulate inside the cleaning components. Cleaning the quartz sleeve after dirt and grime has accumulated can actually coat the outer wall of the sleeve with dirt, resulting in the opposite cleaning effect. Therefore, frequent cleaning, maintenance, and replacement are required. Summary of the Invention

[0037] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0038] Please refer to Figures 1-8 The present application provides a technical solution: comprising a disinfection channel 1;

[0039] In another embodiment provided by the present application, preferably, the disinfection channel 1 is provided with a water outlet at the lower part, the water inlet tank 6 and the water outlet at the lower part of the disinfection channel 1 are respectively arranged at both ends of the lamp row 203, so that the sewage can be injected from one end above the disinfection channel 1, the sewage to be treated flows into the disinfection channel 1 from the water inlet, and flows through the gap between the lamp rows 203, in this process, the sewage receives a sufficient dose of ultraviolet irradiation to achieve sterilization and disinfection, and then is discharged from the water outlet at the lower part of the disinfection channel 1.

[0040] In another embodiment provided by the present application, preferably, the disinfection channel 1 is internally provided with an ultraviolet lamp module 2, the ultraviolet lamp module 2 comprises a mounting frame 201 arranged inside the disinfection channel 1, and the lamp row 203 is detachably mounted at the bottom of the mounting frame 201, which facilitates the installation or disassembly of the lamp row 203.

[0041] The lamp row 203 is arranged in parallel inside the disinfection channel 1, and gaps are arranged between the lamp rows 203;

[0042] The lamp row 203 is preferably a metal frame in which a plurality of ultraviolet lamps are arranged in parallel and are sleeved by quartz sleeves, and the parallel lamp rows 203 form a uniform ultraviolet field covering the entire cross section of the disinfection channel 1, so that when the sewage flows through the gap between the lamp rows 203, it can be uniformly irradiated by ultraviolet light from multiple angles, reducing the optical shadow area or weak irradiation area, and the disinfection effect is good;

[0043] In still another embodiment of the present application, preferably, the surface of the mounting rack 201 is provided with a plurality of through-slots 202 in a linear equidistant array, and the through-slots 202 are configured to cooperate with the flow guide cleaning member 3 to allow the flow guide cleaning member 3 to pass through.

[0044] In still another embodiment of the present application, preferably, the inner side walls of the through-slots 202 on the mounting rack 201 are each provided with a wear-resistant bushing, which is preferably made of an engineering plastic series, such as polytetrafluoroethylene, ultra-high molecular weight polyethylene or polyamide, and has good wear-resistant effect.

[0045] The flow guide cleaning member 3 is arranged in the gap between the lamp rows 203, and the top is provided with a movement driving member 4 and can be driven by the movement driving member 4 to translate along the gap between the lamp rows 203.

[0046] The flow guide cleaning member 3 includes a flow guide water inlet 301, which is in the shape of an "eight" in cross-section and has a small end connected to one end of a connecting shell 302, and the other end of the connecting shell 302 is provided with a flow guide column 303, and the surface of the connecting shell 302 is provided with a plurality of water spray holes 304. Water with a high flow rate flows into the large end of the "eight"-shaped flow guide water inlet 301, enters the connecting shell 302, collides with the outer arc of the flow guide column 303, and is guided to the water spray holes 304 on both sides to flow out, so that the sewage is more evenly distributed in the disinfection channel 1, and the sewage is guided to increase the time of being irradiated by ultraviolet rays, and at the same time, the quartz sleeve of the ultraviolet lamp tube module 2 is washed and self-cleaned by the sprayed sewage.

[0047] In still another embodiment of the present application, preferably, the inner side walls of the water spray holes 304 are provided with a booster nozzle 305, and the water outlet of the booster nozzle 305 faces the lamp rows 203. The booster nozzle 305 is a Venturi tube, which is a product available on the market. The principle is that the water flows through a pipe with a gradually narrowing cross-sectional area, the flow rate increases, and the pressure decreases, so that air is sucked into the side opening and mixed with the water flow to form a gas-liquid mixture, generating a large number of milky white bubbles.

[0048] The reset member 7 is arranged at the top of the disinfection channel 1, the inner side walls of the reset member 7 are provided with a movable rack 5, and the movable rack 5 is connected with the movement driving member 4 through the movable rack 5. The movable rack 5 is provided with a water inlet tank 6 at the top and can cooperate with the reset member 7 to control the lifting of the flow guide cleaning member 3 through the water quantity in the water inlet tank 6.

[0049] In still another embodiment of the present application, preferably, the water inlet tank 6 comprises a tank body 601, the top of the tank body 601 is provided with a water outlet groove 602, and the bottom of the tank body 601 is provided with a plurality of water outlet holes 603. When the water injection amount is small, the water flows out from the water outlet holes 603, and the water remaining in the tank body 601 is insufficient to overcome the force of the spring 703 to press the flow guide cleaning piece 3 into the gap between the lamp rows 203. When the water injection amount is large, the water flows out from the water outlet holes 603, and the water remaining in the tank body 601 is sufficient to overcome the force of the spring 703 to press the flow guide cleaning piece 3 into the gap between the lamp rows 203.

[0050] In still another embodiment of the present application, preferably, the reset piece 7 comprises a fixed frame 701, the inner side wall of the fixed frame 701 is provided at the top with a guide assembly 702 and a spring 703, and the movable frame 5 is connected to the guide assembly 702 and the spring 703. The spring 703 has a plurality of springs 703, which can make the flow guide cleaning piece 3 rise from the gap between the lamp rows 203 to not interfere with the irradiation work of the lamp rows 203 when the water amount in the water inlet tank 6 is insufficient.

[0051] In still another embodiment of the present application, preferably, the guide assembly 702 is a plurality of telescopic sleeves which are inserted together according to the size of the diameter and can be telescoped in multiple sections. The telescopic sleeves occupy a small space when they are contracted, and in the case that the height of the fixed frame 701 is fixed, the telescopic sleeves increase the lifting stroke of the flow guide cleaning piece 3.

[0052] In still another embodiment of the present application, preferably, the flow guide cleaning piece 3, the movement driving piece 4, the movable frame 5 and the water inlet tank 6 are all made of light materials, and the flow guide cleaning piece 3, the movable frame 5 and the water inlet tank 6 can be aluminum alloy, engineering plastic or carbon fiber composite material.

[0053] Working principle: the embodiment provides an industrial sewage rapid treatment equipment based on ultraviolet sterilization. When the water flow is small and the liquid level in the water inlet tank 6 is low, the water flow speed is slow, the kinetic energy is insufficient, and the drag force is insufficient. The reset piece 7 lifts the flow guide cleaning piece 3, keeps the water flow unobstructed, and prevents the suspended solids in the sewage from depositing on the flow guide cleaning piece 3 to cause blockage or form a dead zone.

[0054] When the water flow into the water inlet tank 6 is small and the liquid level is low, the amount of water flowing out from the water outlet holes 603 is large, and the water remaining in the tank body 601 is insufficient to overcome the pre-tightening restoring force of the spring 703, so that the flow guide cleaning piece 3 cannot be pressed into the gap between the lamp rows 203. Under the action of the spring 703, the movable frame 5 is lifted upward, so that the flow guide cleaning piece 3 is lifted and kept at a high position through the movement driving piece 4. The flow channel between the lamp rows 203 is unobstructed, and the sewage can smoothly pass through the ultraviolet disinfection.

[0055] In actual use, according to the demand, the spring 703 with the required pre-tightening restoring force is selected, so that when the water quantity in the water inlet tank 6 is below a certain amount, the flow guide and cleaning member 3 is in the high position, and when the water quantity in the water inlet tank 6 is above a certain amount, the flow guide and cleaning member 3 is in the low position;

[0056] When the water quantity in the water inlet tank 6 is below a certain amount, even if the flow guide and cleaning member 3 does not completely rise out of the gap between the lamp rows 203, as long as it rises, there is a gap below the inside of the disinfection channel 1, so that the water with small quantity flows through, and because the water quantity is small, the liquid level is low when flowing through the disinfection channel 1, it is also difficult to collide with the flow guide and cleaning member 3 which has been raised to a certain height, so the sewage can flow smoothly, and because the water quantity is small and the flow speed is slow, the irradiation time by the ultraviolet lamp tube module 2 can also be increased, even if there is no flow guide and cleaning member 3, the sewage can also be irradiated by the ultraviolet lamp tube module 2 for sufficient time;

[0057] In actual use, the water outlet hole 603 at the bottom of the tank body 601 of the water inlet tank 6 should not be too large, and should be multiple and distributed.

[0058] When the water flow is large and the liquid level in the water inlet tank 6 is high, the water flow speed is fast, the kinetic energy and drag force are large, and the suspended solids in the sewage are difficult to deposit on the flow guide and cleaning member 3 to cause blockage or form a dead zone, the water injection quantity is large, the water flow out of the water outlet hole 603 is less than the water injection quantity, and the water remaining in the tank body 601 is more, and even overflows from the water outlet groove 602 at the top of the tank body 601, and the weight is enough to overcome the force of the spring 703 to press the flow guide and cleaning member 3 down to insert into the gap between the lamp rows 203, so that the flow guide and cleaning member 3 is lowered to the gap between the lamp rows 203 for flow guiding and cleaning, so that the sewage is more evenly distributed in the disinfection channel 1, the sewage is increased by flow guiding to be irradiated by the ultraviolet light, and at the same time, the quartz sleeve of the ultraviolet lamp tube module 2 is washed and self-cleaned by the sprayed sewage;

[0059] The moving driving member 4 can adopt the existing light weight cylinder on the market, and through the extension and contraction of the light weight cylinder, the flow guide and cleaning member 3 at the power output end is driven to translate along a straight line in the gap between the lamp rows 203, so that when the water flows through the flow guide and cleaning member 3, it is driven by the moving flow guide and cleaning member 3 to move along one end of the lamp row 203 to the other end to spray and clean, and the cleaning effect is good;

[0060] When the flow guide and cleaning member 3 is lowered to the working position, the water with fast flow speed flows into the large end of the "8" shaped flow guide water inlet 301, enters the connecting shell 302, collides with the outer arc of the flow guide column 303, is guided to the water spray holes 304 on both sides, flows out through the Venturi tube booster nozzle 305, so that the sewage is more evenly distributed in the disinfection channel 1, the sewage is increased by flow guiding to be irradiated by the ultraviolet light, and at the same time, the quartz sleeve of the ultraviolet lamp tube module 2 is washed and self-cleaned by the sprayed sewage.

[0061] The inside wall of the water spraying hole 304 is provided with a booster nozzle 305, the water outlet of the booster nozzle 305 is directed to the lamp row 203, the booster nozzle 305 is a Venturi tube, the Venturi tube is a product available on the market, the principle is that the water flows through a pipe with a gradually narrowed cross section, the flow rate increases, the pressure decreases, thereby a negative pressure area is generated to realize pressure boosting, at the same time, air is sucked into the side opening and mixed with the water flow, a gas-liquid mixture is formed, a large amount of milky white bubbles are generated, the sprayed water is sprayed on the quartz sleeve of the ultraviolet lamp tube module 2, and the water is guided and self-cleaned at the same time (the ultraviolet lamp tube module 2 and the moving driving member 4 are products available on the market and are connected with an external power supply and an external switch).

[0062] The above has described certain exemplary embodiments of the present application by way of illustration only, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
