Description

Technical Field

[0001] The invention relates to the technical field of biological fouling prevention and control of water pipelines, and in particular to an embedded ultraviolet light killing and expelling marsh clam fouling prevention and control device and method. Background Art

[0002] Water pipeline systems face the challenge of biofouling, especially the fouling caused by organisms such as clams, which has gradually become an important factor affecting the safety and operation efficiency of pipeline systems. Biofouling by clams not only increases the resistance of pipelines and reduces water delivery efficiency, but may also corrode pipeline materials and even cause serious failures such as blockage and leakage, seriously threatening the continuity and safety of water supply. The prevention and control of biofouling by clams is not a one-off process, but requires a systematic, multi-step solution. First of all, it is necessary to understand the biological characteristics of clams and their fouling mechanism. Clams form a firm attachment to the surface of pipelines by secreting foot silk proteins, and can reproduce and spread in the water, gradually forming a large area of ​​fouling layer. Therefore, the first step in fouling prevention and control should be to block the attachment and reproduction of clams by physical or chemical means. However, once fouling is formed, more complex treatment methods are needed to remove it. Traditional cleaning methods, such as mechanical scraping and chemical cleaning, can remove fouling to a certain extent, but often have the disadvantages of low efficiency, damage to pipeline materials, affecting the normal operation of the system, and being environmentally unfriendly and affecting the ecology. In addition, traditional emergency solutions are even more inadequate for important structural parts that have already been fouled, especially those that lack redundant design. These structural parts are often the key nodes of the system. Once they fail due to fouling, it will directly lead to the paralysis of the entire system. However, there are currently no effective emergency solutions specifically for these key parts on the market. This is mainly due to the complexity and systematic nature of fouling prevention and control technologies, as well as the particularity and sensitivity of important structural parts. In such a context, it is particularly urgent to explore an efficient, reliable, and applicable emergency solution for important structural parts that have already been fouled. This requires not only a deep understanding of the mechanisms and characteristics of biofouling by swamp clams, but also the innovative integration of multiple technical means to achieve efficient prevention and control of fouling and non-stop maintenance.

[0003] At present, although there have been many research results and technical means in the field of biofouling prevention and control of swamp clams, there are still many gaps and challenges. On the one hand, the research on the formation mechanism and prevention principle of swamp clam fouling is not in-depth enough, especially the analysis of the internal structure of the fouling layer and the exploration of the removal mechanism still need to be strengthened. On the other hand, most of the existing fouling prevention and control technologies have problems such as singleness and limitations, and it is difficult to meet the needs of different scenarios. Especially when facing important structural parts that have been fouled, there is a lack of special emergency solutions. Specifically, the existing fouling prevention and control technologies mainly include physical cleaning, chemical cleaning, biological control and other methods. Physical cleaning methods such as high-pressure water jets and mechanical scraping can directly remove the fouling layer, but they are easy to damage the pipe material and have low cleaning efficiency. Chemical cleaning methods such as the use of strong acids, strong alkalis, and strong oxidizing chemicals can effectively dissolve the fouling layer, but they often cause pollution to the environment and require shutdown operations. Biological control methods prevent and control fouling by introducing natural enemies, but the effect is slow and difficult to control. In addition, most of the existing fouling prevention technologies need to be carried out in a shutdown state, which will undoubtedly have a serious impact on the continuity and stability of the water supply system. Especially when facing important structural parts that have been fouled, the shutdown operation is even more unacceptable. Therefore, it is particularly important to develop a technical means to prevent fouling without stopping the system.

[0004] In summary, the prevention and control of biofouling by swamp clams needs to be carried out in multiple steps, from blocking attachment to removing fouling, and then to preventing occurrence. Each link needs to be supported by reliable technical means. For important structural parts that have already been fouled, an efficient, reliable, non-stop, and environmentally friendly emergency solution is needed. However, the current research in this field is still insufficient, and a complete theoretical and technical system has not yet been formed. Summary of the invention

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following describes the embedded ultraviolet light killing and expelling clam pollution prevention and control device and method according to the embodiment of the present invention with reference to the accompanying drawings.

[0030] Figure 1 The invention is a block diagram of an embedded ultraviolet light pollution prevention and control device for killing and expelling clams according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the embedded ultraviolet light killing and expelling clam pollution prevention and control device 10 includes: a front dual-channel filter 101, an oxidant injection device 102, an ultraviolet oxidation catalyst 103, an embedded light killing device 104 and a numerical control system 105.

[0032] Among them, the front dual-channel filter 101 includes a single channel and a spare channel, which is used to filter the adult clams in the target risk pipeline through the single channel, and switch to the spare channel when it is blocked to the limit value. The oxidant injection device 102 is arranged at the downstream pipeline of the front dual-channel filter 101, and is used to inject an environmentally friendly self-quenching oxidant and disperse the environmentally friendly self-quenching oxidant into the incoming flow of the front dual-channel filter 101. The ultraviolet oxidation catalyst 103 is arranged at the downstream pipeline of the oxidant injection device 102, and is used to activate the environmentally friendly self-quenching oxidant into free radical components through ultraviolet catalysis, so as to decompose and remove the contamination of the limpet protein in the incoming flow and maintain the internal surface of the system clean. The embedded light killing device 104 is arranged at the downstream pipeline of the ultraviolet oxidation catalyst 103 and embedded in the target risk pipeline, and is used to kill and expel the larvae, juveniles and adult shellfish trapped on the inner wall of the target risk pipeline through medium-pressure ultraviolet band light and blue-green band light, so as to prevent the individual development of the clams and prevent the clams from attaching and reproducing on the surface of the core structural parts. The numerical control system 105 is used to monitor the operating status of the pre-dual-channel filter 101, the oxidant injection device 102, the ultraviolet oxidation catalyst 103 and the embedded light killing device 104, and adjust the limit value of the pre-dual-channel filter 101, the amount of the oxidant injection device 102, the start and stop of the ultraviolet oxidation catalyst 103 and the start and stop of the embedded light killing device 104 according to the operating status.

[0033] In some embodiments, the pre-dual-channel filter 101 serves as the first line of defense of the device. Based on the detection of the operating status by the numerical control system 105, when the filter is fully loaded, the operating pipeline is switched through the single-channel operation and the backup channel switching mechanism. Maintenance can be carried out without stopping the machine, and the channels can be switched automatically. This can effectively filter large-sized clams entering the system, ensure that the pipelines are unobstructed, and maintain the normal operation of the device.

[0034] In some embodiments, the oxidant injection device 102 includes a nozzle, a disperser, a pump tube, and a pump injector, wherein when the target risk pipeline requires oxidation-assisted cleaning, an environmentally friendly self-quenching oxidant is injected into the target risk pipeline through the pump tube and the pump injector, and is effectively dispersed in the incoming flow of the pre-dual-channel filter by using the nozzle and the disperser. The environmentally friendly self-quenching oxidant includes hydrogen peroxide and ozone.

[0035] In some embodiments, the ultraviolet oxidation catalyst 103 activates the oxidants dispersed in the incoming air flow into highly active free radical components through ultraviolet catalysis. The free radical components specifically react with the adhesive byssus protein secreted by the clams, destroying its structure and reducing its adhesion, so that the byssus cannot reach an effective strength to contaminate the lamp tube wall and other inner surfaces, thereby effectively preventing the clams from contaminating the inner wall of the pipeline and effectively preventing the reduction of light transmission efficiency due to contamination of the structural surface of the quartz tube 1045.

[0036] In some embodiments, Figure 2 As shown, the embedded light killing device 104 includes:

[0037] The quartz tube 1045 is nested inside the target risk pipeline through a plurality of support frames 1043, and the support frames 1043 are adjusted to achieve a stress stabilization condition;

[0038] A connecting pipe 1044, which is connected to the quartz tube 1045 and the downstream pipeline of the ultraviolet oxidation catalyst 103 through a sealing structure 1046, so as to connect the quartz tube 1045 and the downstream pipeline of the ultraviolet oxidation catalyst 103;

[0039] A plurality of support frames 1043, wherein the plurality of support frames 1043 are nested outside the quartz tube 1045 to leave a gap between the quartz tube 1045 and the target risk pipeline, so that the quartz tube 1045 is in a suspended state and can operate stably under the target load and incoming flow conditions;

[0040] Ultraviolet generator 1041, which is arranged inside quartz tube 1045, is used to release medium-pressure ultraviolet light. Medium-pressure ultraviolet light is the light absorption peak of biological genetic material, which mediates ultraviolet light to directly penetrate cells and inactivate genetic components, blocking the development of fouling of swamp clams, that is, inactivating genetic components of swamp larvae and adult clams that are retained on the inner wall of the target risk pipeline. In addition, this stage can still further activate oxidants and remove the fouling of the tube wall by foot silk protein;

[0041] The blue-green band light generator 1042 is arranged inside the quartz tube 1045. Based on the light-avoiding property of clams, the blue-green band light is used to drive away the larvae and adult clams trapped in the core structural parts area of ​​the target risk pipeline, so that the clams do not form contamination on the surface of the core structural parts. The blue-green band light generator 1042 releases the blue-green band light in the range of 520-600nm, and the blue-green band light expulsion should be greater than 8200LUX on the surface of the core components.

[0042] In some embodiments, the embedded light-killing device 104 further includes key components such as a power transmission unit, a sliding loading unit, a sensor, and a cooling fan. All components of the embedded light-killing device 104 need to be assembled accurately to ensure sealing and stability, laying a foundation for subsequent embedded installation.

[0043] A power transmission unit, the power transmission unit is connected to the ultraviolet generator 1041 and the blue-green band light generator 1042 respectively to supply power to the ultraviolet generator 1041 and the blue-green band light generator 1045;

[0044] A sensor, the sensor is connected to the numerical control system 105 to monitor the operating status of the embedded light killing device 104 and transmit the operating status to the numerical control system 105;

[0045] A cooling fan is nested in the quartz tube 1045 through an internal support frame to cool the ultraviolet generator 1041 and the blue-green band light generator 1042 .

[0046] Therefore, the working process of the embedded ultraviolet light killing and expelling clam pollution prevention and control device proposed in the embodiment of the present invention is:

[0047] First, according to the scale of pollution monitored during pipeline maintenance, pipeline load pressure, flow rate, pipe diameter and pipeline material, the pre-pre-dual-channel filter 101, the size of the embedded equipment, the light power of the ultraviolet oxidation catalyst 103, the blue-green band light expelling lamp of the embedded light killing device 104 and the medium-pressure ultraviolet band light long-lasting killing lamp power are designed and configured.

[0048] The assembled embedded light killing device 104 integrating ultraviolet killing and blue-green band light expulsion is embedded into the contaminated pipeline structure and installed through the inspection port. During the installation process, the support frame 1043 needs to be adjusted to ensure that the equipment operates stably under the target load and incoming flow conditions. The equipment is then debugged to verify the working performance of the ultraviolet and blue-green band light generators to ensure that the optical power and irradiation range meet the design requirements.

[0049] The flow pipe is remodeled and a front dual-channel filter 101 is installed. The front dual-channel filter 101 separates the adult clams transported along the pipeline from the pipeline water flow through the physical size screening principle. The adult clams are intercepted on the filter screen. The filter monitors the operation status in real time through the numerical control system 105 or detects the load rate of the filter screen through the front and rear flow sensors. When the filter is fully loaded, the system automatically alarms and prompts the safety officer, and switches to the backup flow path through the valve to clean the filter without stopping the machine. After maintenance, it switches back to the main line to complete a cycle of maintenance work.

[0050] The oxidant injection device 102 injects an environmentally friendly self-quenching oxidant into the pipeline flow through an external high-pressure pumping principle.

[0051] The UV oxidation catalyst 103 is based on the principle of free radical production by activation of an environmentally friendly self-quenching oxidant under ultraviolet light. The activated free radicals can clean the key protein of the fouling of the swamp clam - the byssus: the byssus is composed of a stack of multiple proteins, among which the key components are the mfp-5 protein loaded on the surface of the substrate and the shell protein used to isolate the external environment from the protein. The bottom protein is bonded to the surface of the material through hydrogen bonds mainly composed of DOPA residues and tyrosine residues; and the shell protein forms a protective layer through the coordination of DOPA residues and heavy metals. The free radicals activated by the oxidant can preferentially react with the part of the benzene ring that takes away the hydroxyl structure, so the free radicals can preferentially destroy the core structure of the fouling protein, resulting in reduced protein adhesion, weakened structural strength, and step-by-step decomposition in the advanced oxidation field.

[0052] The core structure of the embodiment of the present invention is an embedded light killing device 104, which is embedded in the core structural part area of ​​the target risk pipeline. The medium-pressure ultraviolet light released by the ultraviolet generator 1041 destroys the biological genetic tissue and kills the organisms retained in the light field. In the embodiment of the present invention, it mainly targets marsh clams; the blue-green band released by the blue-green band light generator 1042 drives away the marsh clams, which utilizes the specific detachment reaction of the marsh clams to light; the reason for using medium-pressure ultraviolet light to kill is that the absorption rate of medium water for mid-sub-ultraviolet is lower, and the utilization rate of medium-pressure ultraviolet light is higher in the case of effective killing; the reason for using blue-green band light is that the blue-green band light is the light band with the weakest absorption by medium water in the visible band, so the use of this band can prevent algae outbreaks and effectively drive away the attachment of marsh clams to the core pipeline. In addition, the ultraviolet light of the embedded light killing device 104 also has the function of activating oxidants to become free radicals, which can effectively clean the floating and adhering foot silk debris on the inner surface, thereby effectively reducing the maintenance work of the inner surface of the equipment.

[0053] In addition, when the ultraviolet generator 1041 or the blue-green band light generator 1042 in the embedded light killing device 104 fails, the accessories are taken out and replaced through the reserved inspection port, and the equipment maintenance work is completed by reinstalling and aligning through the pulley after the inspection, and closing the inspection port. During the inspection, the water pipeline does not need to stop supplying water. After the inspection is completed, the core structural parts are reinstalled and aligned through the pulley, and the inspection port is closed to complete the equipment maintenance work. At the same time, the pollution of the swamp clams in the pipeline is regularly monitored and evaluated, and the necessary optimization and adjustment of the device are made according to the evaluation results.

[0054] In addition, the numerical control system 105 automatically monitors the operating status of each module and automatically adjusts according to preset parameters to ensure that the equipment is always in the optimal operating state.

[0055] The embedded ultraviolet light killing and expelling clam pollution prevention and control device proposed in the embodiment of the present invention is further described below through a specific embodiment.

[0056] like Figure 3 and 4 As shown, the pre-dual-channel filter 101, the oxidant injection device 102, the ultraviolet oxidation catalyst 103, the ultraviolet generator 1041, the blue-green band light generator 1042 and the numerical control system 105 in the device are parameterized. Among them, the key parameters of each module are as follows: the pre-dual-channel filter 101 is designed to effectively filter large-sized swamp clam shellfish with a size of more than 10 mm, ensuring that the water flow entering the device does not contain large particles of dirt; the oxidant injection device 102 uses an environmentally friendly self-quenching oxidant 10% hydrogen peroxide, which is injected into the pipeline at a flow rate of 10L / h through a high-pressure pump; the ultraviolet oxidation catalyst 103 has a built-in ultraviolet light source with a wavelength set to 285nm, which activates the oxidant into highly active free radicals through ultraviolet catalysis, effectively decomposes the contamination of the swamp clam foot silk protein, and self-cleans the inner wall of the pipeline; the ultraviolet generator 1041 is an ultraviolet light source composed of a 4-segment ultraviolet lamp group with a wavelength of 285nm. The wavelength is set to 285nm, which can directly penetrate the cells and inactivate genetic components, completely kill the retained larvae and adult shellfish of the marsh clam, and prevent the main pipe from polluting the downstream of the marsh clam habitat; the blue-green band light generator 1042 is provided with a blue-green band light dispersing lamp, and the wavelength range of the light source is set at 525nm. The illumination intensity of the core component reaches 200mW / cm2, and the light-avoiding characteristics of the marsh clam are used to prevent it from adhering to the surface of the pipeline; the CNC system integrates remote monitoring, automatic adjustment and fault warning functions to ensure the precise control of the operating parameters of each module. In this specific embodiment, the ultraviolet light power is maintained at 100W in four groups, and the blue-green band light power is set to 10W×4 groups.

[0057] During daily operation, the numerical control system 105 automatically monitors the operating status of each module and automatically adjusts according to the preset parameters to ensure that the equipment is always in the optimal operating state. When the ultraviolet generator 1041 or the blue-green band light generator 1012 in the core structure fails, the reserved maintenance port ( Figure 3 Take out (right side) Figure 2 ) and replace fittings without stopping the water supply, ensuring continuous operation of the piping system.

[0058] The embedded ultraviolet light killing and expelling clam pollution prevention and control device proposed in the embodiment of the present invention has the following beneficial effects:

[0059] (1) The embodiment of the present invention achieves efficient prevention and control of fouling of Marsh Clams by integrating a pre-filter, an ultraviolet killing lamp, a blue-green band light expelling lamp and an ultraviolet oxidation catalyst, while supporting non-stop maintenance to ensure continuous operation of the pipeline system. Compared with the prior art, the embodiment of the present invention significantly improves the efficiency of fouling control and the reliability of the system;

[0060] (2) Multi-technical integration and synergy: The embodiments of the present invention combine multiple technical means such as physical filtration, ultraviolet killing, light expulsion and advanced oxidation, and show a strong synergistic effect in fouling prevention and control. In particular, ultraviolet light can activate oxidants while killing organisms, further improving the cleaning effect;

[0061] (3) The built-in numerical control system of the embodiment of the present invention can accurately control the operating parameters of each module, realize remote monitoring, automatic adjustment and fault warning, reduce the need for manual intervention, and improve the stability and safety of equipment operation. Compared with the traditional method that relies on manual inspection, the embodiment of the present invention has taken an important step in intelligent management;

[0062] (4) The embodiment of the present invention adopts environmentally friendly oxidants (such as hydrogen peroxide and ozone) for auxiliary cleaning, which reduces pollution to the environment. The advanced oxidation method can realize self-cleaning of the oil film and protein pollution on the inner wall of the pipeline to improve the light transmission coefficient of the quartz glass. By controlling the amount of oxidant input, auxiliary emergency chemical killing can be achieved. At the same time, the design of non-stop maintenance avoids the waste of resources caused by shutdown and maintenance, reflecting the concept of green and sustainable development.

[0063] (5) The embodiments of the present invention can be customized according to the scale of pollution, load pressure, flow rate and other parameters of different pipeline systems, and the power and size of each module can be flexibly configured; the equipment can also be more convenient to maintain and upgrade by reserving inspection ports and modular design, thereby enhancing its adaptability and flexibility in practical applications.

[0064] (6) The embedded ultraviolet light killing and expelling mud clam fouling prevention and control equipment of the embodiment of the present invention is particularly suitable for important structural parts that have already been fouled but lack redundant design, such as cooling water systems. Through the precisely designed integrated equipment, the device can be directly embedded in these key parts without interrupting the operation of the system, quickly start and effectively remove mud clam fouling, prevent the fouling from further deteriorating and affecting the system performance, and also ensure the safe operation of important structural parts, thereby extending the service life of the overall system.

[0065] Next, the embedded ultraviolet light killing and expelling clams pollution prevention and control method proposed in an embodiment of the present invention is described with reference to the accompanying drawings.

[0066] Figure 5 A schematic flow chart of an embedded ultraviolet light method for killing and expelling clams for pollution prevention and control provided in an embodiment of the present invention.

[0067] like Figure 5 As shown, the embedded ultraviolet light killing and expelling clams pollution prevention and control method comprises the following steps:

[0068] In step S501, the front dual-channel filter, the oxidant injection device, the ultraviolet oxidation catalyst and the embedded light killing device are connected in sequence and embedded in the target risk pipeline.

[0069] In step S502, the front dual-channel filter, the oxidant injection device, the ultraviolet oxidation catalyst and the embedded light killing device are connected to the numerical control system respectively.

[0070] In step S503, based on the front dual-channel filter, the single-channel and backup channel switching mechanism is used to check and filter the adult clams in the target risk pipeline.

[0071] In step S504, an environmentally friendly self-quenching oxidant is injected into the downstream pipeline of the front dual-channel filter using an oxidant injection device.

[0072] In step S505, the environmentally friendly self-quenching oxidant is activated into free radical components by a UV oxidation catalyst, and the free radical components are used to decompose and remove the fouling of the byssin in the biogas flow.

[0073] In step S506, based on the embedded light killing equipment, medium-pressure ultraviolet band light and blue-green band light are released to inactivate the genetic components of the larvae and adult clams stranded on the inner wall of the target risk pipeline by the medium-pressure ultraviolet band light, and the larvae and adult clams stranded in the core structural parts area of ​​the target risk pipeline are driven away by blue-green band light.

[0074] In step S507, the numerical control system is used to monitor the operating status of the front dual-channel filter, the oxidant injection device, the ultraviolet oxidation catalyst and the embedded light killing device in real time, and the limit value of the front dual-channel filter, the release amount of the oxidant injection device, the start and stop of the ultraviolet oxidation catalyst and the start and stop of the embedded light killing device are adjusted according to the operating status.

[0075] It should be noted that the above explanation of the embodiment of the embedded ultraviolet light killing and expelling clam pollution prevention and control device is also applicable to the embedded ultraviolet light killing and expelling clam pollution prevention and control method of this embodiment, which will not be repeated here.

[0076] The embedded ultraviolet light killing and expelling clams pollution prevention and control method proposed in the embodiment of the present invention has the following beneficial effects:

[0077] (1) The embodiment of the present invention achieves efficient prevention and control of fouling of Marsh Clams by integrating a pre-filter, an ultraviolet killing lamp, a blue-green band light expelling lamp and an ultraviolet oxidation catalyst, while supporting non-stop maintenance to ensure continuous operation of the pipeline system. Compared with the prior art, the embodiment of the present invention significantly improves the efficiency of fouling control and the reliability of the system;

[0078] (2) Multi-technical integration and synergy: The embodiments of the present invention combine multiple technical means such as physical filtration, ultraviolet killing, light expulsion and advanced oxidation, and show a strong synergistic effect in fouling prevention and control. In particular, ultraviolet light can activate oxidants while killing organisms, further improving the cleaning effect;

[0079] (3) The built-in numerical control system of the embodiment of the present invention can accurately control the operating parameters of each module, realize remote monitoring, automatic adjustment and fault warning, reduce the need for manual intervention, and improve the stability and safety of equipment operation. Compared with the traditional method that relies on manual inspection, the embodiment of the present invention has taken an important step in intelligent management;

[0080] (4) The embodiment of the present invention adopts environmentally friendly oxidants (such as hydrogen peroxide and ozone) for auxiliary cleaning, which reduces pollution to the environment. The advanced oxidation method can realize self-cleaning of the oil film and protein pollution on the inner wall of the pipeline to improve the light transmission coefficient of the quartz glass. By controlling the amount of oxidant input, auxiliary emergency chemical killing can be achieved. At the same time, the design of non-stop maintenance avoids the waste of resources caused by shutdown and maintenance, reflecting the concept of green and sustainable development.

[0081] (5) The embodiments of the present invention can be customized according to the scale of pollution, load pressure, flow rate and other parameters of different pipeline systems, and the power and size of each module can be flexibly configured; the equipment can also be more convenient to maintain and upgrade by reserving inspection ports and modular design, thereby enhancing its adaptability and flexibility in practical applications.

[0082] (6) The embedded ultraviolet light killing and expelling mud clam fouling prevention and control equipment of the embodiment of the present invention is particularly suitable for important structural parts that have already been fouled but lack redundant design, such as cooling water systems. Through the precisely designed integrated equipment, the device can be directly embedded in these key parts without interrupting the operation of the system, quickly start and effectively remove mud clam fouling, prevent the fouling from further deteriorating and affecting the system performance, and also ensure the safe operation of important structural parts, thereby extending the service life of the overall system.
