Description

Eco-friendly ultra-fine oxygen water spraying system {ECO-FRIENDLY SYSTEM CAPABLE OF SPRAYING ULTRA FINE OXYGEN WATER PARTICLES}

The present invention relates to an eco-friendly ultra-fine oxygen water injection system, and more specifically, to an eco-friendly ultra-fine oxygen water injection system equipped with technical means to purify water for clean roads or salt water for road snow removal and anti-icing.

In general, in closed water bodies such as rivers, ponds, lakes, dams, reservoirs, etc., where water is not active and stagnant, surface sewage, domestic sewage, factory and agricultural and livestock wastewater, etc. continuously flow into the water, causing the concentration of pollutants in the water to increase. It increases.

Nutrients including nitrogen compounds and phosphates among pollutants cause eutrophication in fresh water because they promote the growth and proliferation of microorganisms that cause organic matter decomposition.

Eutrophication refers to a phenomenon in which nutrients such as nitrogen and phosphorus increase in freshwater due to the decomposition of organic matter by microorganisms, causing abnormal growth of algae. Such eutrophication causes serious damage by reducing the turbidity of fresh water, generating foul odors caused by decaying matter, and, in severe cases, destroying the ecosystem of the lake, such as causing mass death of underwater fish. In addition, oxygen is not supplied to the lower layer of a closed water body where water is stagnant with little flow, causing water pollution to worsen from the bottom.

Therefore, in closed water areas, it is important to maintain a balance so that the amount of nutrients such as nitrogen and phosphorus contained in the aquatic ecosystem does not exceed its own purification capacity, and to purify sinking organic matter and heavy metals by increasing the dissolved oxygen in the water as much as possible. It is very important to ensure that it operates smoothly.

However, despite the increase in sewage and wastewater purification facilities in many dams, reservoirs, and lakes in the country, water quality deterioration is gradually worsening due to the influx of large amounts of pollutants and the formation of dense layers due to long-term freshwater. am.

Among the major conventional water quality improvement methods, direct purification methods by physical methods include coagulation sedimentation, direct sedimentation, filtration, aeration, circulation, water purification, and phosphorus recovery technology, and biological methods include direct oxidation, vegetation purification, microbial agents, and enzymes. There are methods such as fixation, but as seen above, short-term purification and local action have limitations in purifying appeal.

With the development of science and technology, various types of chemicals are mass-produced and used, and environmental pollution caused by synthetic chemicals is emerging as a social problem. In particular, water environmental pollution caused by non-degradable substances that cannot be treated by general methods is very serious. Serious. There is a problem in that it is difficult to treat harmful non-degradable contaminants using only conventional physical or biological methods.

In addition to the environmental pollution problem of closed water bodies where water is stagnant and inactive, water pollution caused by early rainfall is also causing serious environmental problems.

When rainfall occurs in areas paved with concrete or asphalt, rainwater infiltration and retention functions are reduced, causing highly polluted substances from the initial rainfall to flow out into water systems such as nearby sewers and rivers, adversely affecting the water system.

Pollution that occurs through unspecified emission paths such as roads, farmlands, and construction sites is called nonpoint pollution. Nitrogen oxides (NOx), the main culprit of fine tire dust or fine dust accumulated on road surfaces, and nitrogen oxides (NOx) remaining in farmland. Pesticides, dust generated from construction sites, etc. are non-point pollutants, and when it rains, they are washed away with rainwater and become the main cause of river pollution. The reason why these non-point pollutants are a problem is that pollutants generated in unspecified places flow directly into rivers without special filtration when it rains, so they quickly pollute water quality. Water pollution is much more serious than other types of pollution because it does not just end with the water becoming turbid, but can also cause mass death of fish or destroy the habitats of animals and plants, disrupting the ecosystem.

Recently, interest in non-point pollution reduction devices such as infiltration facilities, retention facilities, and filtration facilities to treat non-point pollution sources caused by initial rainfall is increasing.

Infiltration facilities and retention facilities, called natural non-point pollution reduction technologies, are said to be effective, but they have the disadvantage of taking up a lot of land, so many filtration facilities, called filtration-type non-point pollution treatment facilities, are installed along with natural non-point pollution reduction facilities. For example, in Patent Document 1, a plurality of fiber unit filters are sequentially arranged adjacent to each other inside the contaminant collection pipe, and as contaminated water flows through the contaminant collection pipe, contaminants are filtered and pass through the drain hole of the contaminant collection pipe. A non-point source filtration type treatment device is disclosed, which is characterized in that the pollutants are discharged from the outside of the sedimentation tank.

While filtration-type non-point pollution treatment facilities have the advantage of requiring less land area and faster treatment speed compared to natural types, they have the disadvantage of requiring maintenance such as regular cleaning and replacement of filter media.

In addition, existing filter media only have the function of filtering out pollutant particles, so they have the vulnerability of allowing harmful substances such as nitrogen oxides (NOx) and sulfur oxides (SOx), the main culprits of fine dust, to pass through without being decomposed.

Water such as rainwater or river water collected in storage facilities as described above is widely used as road cleaning water. For example, Patent Document 2 includes a storage tank installed underground in which cleaning water containing gray water and/or groundwater is stored, a water pipe with one end connected to the storage tank and the other end extending upward to below the center of the paved road surface, and a water pipe. A water supply pipe connected to and extending along the direction of travel of the vehicle below the center of the paved road surface, one end connected to the water supply pipe and the other end extending above the center of the paved road surface, and a plurality of branches spaced apart along the longitudinal direction of the water supply pipe. It is equipped with an engine, a plurality of spray nozzles connected to these branch pipes to spray cleaning water perpendicular to the direction of travel of the vehicle, and a pressurized pump connected to a storage tank to provide the flow pressure of the cleaning water and the spray pressure of the spray nozzles. An automatic pavement water cleaning device is disclosed.

However, the conventional automatic pavement water cleaning device cannot process foreign substances contained in the water stored in the reservoir and sprays them onto the road surface through the spray nozzle, which may cause problems such as clogging of the spray nozzle or lowering of spray pressure. .

In addition, harmful substances such as nitrogen oxides (NOx) and sulfur oxides (SOx), as well as bacteria such as E. coli, remain in the water of the reservoir, so there is concern that secondary pollution such as air pollution or water pollution may occur after being sprayed on the road. there is.

It includes a valve box 108 with a built-in electric valve 109.

The water level sensor is installed on one side of the storage tank 100 and measures the water level of clean road liquid or road anti-icing liquid to be used for road spraying. The water level sensor may be composed of various water level measuring means, such as an Ottogi-type sensor, an ultrasonic sensor, a float-type sensor by raising and lowering a buoy, a laser sensor, and a scale-type water level gauge. The control board connected to the water level sensor has a predetermined housing, and the inner space of the housing can be filled with polybutene (polybutylene, PB) or insulating oil so that the circuit board is submerged and treated as waterproof.

The storage tank 100 has an internal space that can accommodate liquid such as clean road water or salt water for road snow removal and anti-icing. The liquid (water) stored in the storage tank 100 is usually rainwater secured through rainwater retention tanks at subway stations, river water obtained from rivers connected to various non-point pollution sources, and water used for home, industrial, and agricultural purposes. do.

The upper part of the storage tank 100 is provided with an inlet part consisting of an inlet and a cover for inputting water for the clean load, and the lower part is provided with an outlet part consisting of a pipe for discharging the stored water to the outside. The road liquid injection system according to the present invention is operated as a clean road injection system using groundwater or water from a rainwater retention tank in the summer, and in the winter, it is sprayed with salt water for road snow removal and icing prevention that contains a snow removal agent such as calcium chloride to melt the snow accumulating on the road. It can be operated as a system.

It is preferable that a vertically arranged stirrer (not shown) is provided at the inner center of the storage tank 100. The stirrer has a structure where stirring blades are installed below a motor fixed to the top of the storage tank 100. The stirrer slowly rotates the stirring blade to stir the fluid stored in the storage tank 100, thereby preventing salt powder, etc. from settling in the winter or preventing the fluid inside the storage tank 100 from freezing. The installation structure of the stirrer is disclosed in more detail in Registered Patent Publication No. 10-2073520, for which the present applicant has previously applied and been granted a patent.

The first oxygen generator 20 is disposed around the storage tank 100 and performs the function of increasing the amount of dissolved oxygen in the liquid to be (or introduced into) the storage tank 100. Preferably, the first oxygen generator 20 may generate oxygen such that the amount of dissolved oxygen in the liquid sprayed from the spray nozzle 120 is 10 to 55 ppm.

As shown in FIG. 2, the first oxygen generator 20 includes an oxygen supplier 20a that provides oxygen gas, and the oxygen gas supplied from the oxygen supplier 20a is atomized to produce fine oxygen bubbles in the liquid. It includes an oxygen bubble generator (20b) that generates oxygen bubbles.

The oxygen bubbles generated from the oxygen bubble generator 20b are preferably microbubbles or nanobubbles with an average diameter of 1 micrometer (㎛) or less.

The filter 10 is disposed at the front of the storage tank 100 and has a filter capable of filtering raw water disposed inside. Preferably, a first flow meter 11 is disposed at the inlet of the filter 10 to measure the flow rate of raw water before it is filtered.

For example, if the measured value of the second flow meter 12 is half that of the first flow meter 11, the filter replacement controller determines that the filter of the filter 10 is approximately 50% clogged and sends an alarm notifying filter replacement. can be output.

The DO measuring unit is installed in the storage tank 100 and measures the amount of dissolved oxygen in the liquid contained within the storage tank 100.

The oxygen generation controller (not shown) performs control to increase the dissolved oxygen amount by selectively operating the first oxygen generator 20 when the dissolved oxygen amount measured by the DO measuring unit is less than the set value.

According to another embodiment of the present invention, as shown in FIG. 3, the second oxygen generator 20' is disposed inside the storage tank 100 to increase the amount of dissolved oxygen in the liquid.

As shown in FIG. 4, the second oxygen generator 20' contains potassium superoxide (KO ₂ ), perfluorodecalin (C ₁₀ F ₁₈ ), and sodium percarbonate (2Na ₂ CO ₃ ·3H ₂ O ₂ ). and an oxygen-generating composition consisting of hydrogen peroxide (H ₂ O ₂ ). Preferably, in order to make the amount of dissolved oxygen in the liquid in the storage tank 100 10 to 55 ppm, the content of perfluorodecalin (C ₁₀ F ₁₈ ) may be 0.5 to 10 wt% based on the total weight of the oxygen generating composition.

Referring again to FIG. 1, the pump 104 is connected to the discharge portion of the storage tank 100 through a predetermined pipe and pumps the liquid discharged from the storage tank 100 at a set flow rate and pressure. It is desirable that at least two pumps 104 are provided and one of the two serves as an auxiliary pump.

The air supply device 103 is installed on one side of the pipe connected to the storage tank 100 and supplies air to discharge the remaining amount of fluid in the pipe to the outside through the spray nozzle 112. The air supply device 103 may be connected to a separate air compressor, or alternatively, the air supply device 103 itself may be configured as an air compressor. When the road surface washing mode is terminated, the air supply device 103 discharges all remaining clean road water, such as groundwater, spring water, or tap water, remaining in the entire pipe through air pressure to prevent pipes from freezing and bursting in the winter. In addition, when the winter season ends and the road ice prevention mode ends, it discharges all the salt water remaining in the pipe using air pressure. If salt water is sprayed on the road surface outside of the winter season, there is a risk of causing a traffic accident by making the road surface slippery. The air supply device 103 discharges salt water remaining in the pipe through the spray nozzle 112 when the road anti-icing mode is terminated, thereby preventing salt water from being sprayed during the road surface washing mode.

The liquid discharged from the storage tank 100 and pumped by the pump 104 is supplied to the pipe 111 via the main pipe 105.

The pump station is a facility that surrounds the outside of the pump (104), main pipe (105), air supply device (103), control panel (106), etc. to protect it. The pump station may be composed of a house made of concrete structure, etc., or a container.

The control panel 106 controls the operation of the pump 104 to control the flow rate and pressure of the liquid, and on/off control. The control panel 106 communicates with the remote control device 107, which consists of a remote control system including a remote mobile phone (smart phone) 103a and/or a central control device 103b, which is a computer installed in the central control room. Can be controlled remotely. The remote control device 107 can perform data communication with the control panel 106 through wired or wireless Internet or various serial communications. Specifically, communication between the remote control device 107 and the control panel 106 may be performed according to at least one communication protocol selected from, for example, LoRa, CDMA, LTE, Ethernet, CAN, RS422, RS232, and RS485. . At least one communication protocol selected from LoRa, CDMA, LTE, RS422, RS232, and RS485 for communication between the control panel 106, the reservoir 100, the pump 104, the detection unit 113, and the electric valve 109. This can be used.

The control panel 106 preferably has a metal enclosure and can be spatially installed within the pump station. The control panel 106 controls the valve box 108, controls the pump 104 or various control valves in the pump station, and the main piping 105, controls the operation of the agitator, and switches between manual and automatic operation modes. Perform control, etc.

Wireless communication that can be used in the present invention can employ various wireless communication standards such as LoRa, CDMA, LTE, and 5G, as well as Internet-related communication standards such as Bluetooth, LoRa communication, and NB-IOT.

The valve box 108 may be installed as an external or embedded type exposed to the outside on the road surface or around the road. The valve boxes 108 may be arranged one for each injection nozzle 120 in one-to-one correspondence. This one-to-one control method can be applied to a salt water injection system in which each injection nozzle 112 is arranged at wide intervals of, for example, tens of meters. Alternatively, the valve box 108 may be disposed one by one for each injection zone including a plurality of injection nozzles 120, as shown in FIG. 9. This batch control method can be applied to a cooling rod system in which multiple spray nozzles 120 are relatively densely arranged to clean or cool the road surface with a furnace.

The road liquid injection system detects the injection state and standby state of the injection nozzle 112 and uses a remote control device (107) consisting of a remote control system including a mobile phone (107a) or a central control device (107b) through the control panel (106). It is provided with a detection unit 113 that transmits to.

The detection unit 113 includes a fine dust detection sensor that detects fine dust, a hazardous substance detection sensor that detects at least one selected from sulfur oxides, nitrogen oxides, volatile organic compounds, and radon, and other hazardous substances prescribed by Ordinance of the Ministry of Environment, It is equipped with at least one of a temperature and humidity sensor that detects temperature and humidity, a rain sensor that detects the amount of snow or rain, and a road surface sensor that checks the condition of snow or rain accumulated on the road surface. Additionally, the detection signal output from the detection unit 113 is transmitted to the control panel 106 through the communication card box 114.

Additionally, around the detection unit 113, there is a video surveillance camera 116 that allows you to check the spraying status in real time, and an LED or liquid crystal display that displays the spraying state of the liquid, fine dust concentration, and weather conditions. An information display board 117 consisting of devices, etc. may be placed. In addition, a broadcasting facility (not shown) equipped with a speaker that outputs voice to guide and control the on-site situation in real time in conjunction with the information display board 117 may be installed on one side of the surrounding area.

The information signboard 118 is, for example, an LED signboard installed on a predetermined support in the center of the road or on the ground around the road and displays “water spraying in progress” or “salt water spraying in progress” for vehicles entering the section where the spray nozzle 112 is installed. , displays phrases such as “safe driving”. The information board 118 displays the phrase “Water spraying” or “Salt water spraying” before the vehicle enters the section where the spray nozzle 120 is installed, so that the vehicle driver can recognize the water spraying status in advance. , When a vehicle exits the section where the spray nozzle 120 is installed or when water spray is stopped, the phrase “safe driving” is displayed to alert the driver's attention.

The spray nozzle 120 may be any one selected from a floor nozzle, a marker nozzle, and a gaze guide nozzle. The spray nozzle 120 is installed on the road surface and connected to the pipe 111, receives the liquid through the pipe 111, and sprays it onto the road surface. In particular, the floor nozzle refers to a nozzle whose top surface is located on the same plane as the surface of the road surface and whose outer shape matches the overall floor surface. A representative floor nozzle is the '360-degree spray floor nozzle' published in Korean Patent No. 10-2118827, for which the present applicant has previously applied and been granted a patent. The 360-degree spray floor nozzle includes a base with a flat upper surface so as to be placed on the same plane as the furnace road surface, a nozzle block assembled on the lower surface of the base, and a disk mounted on the nozzle block to be positioned in the center of the base so that it can be raised and lowered. It includes a type valve (see V in FIG. 12). When liquid is supplied to the injection nozzle through the pipe 111, the disk-shaped valve V is instantly pushed up (pops up) by water pressure, opening the injection hole, and at the same time, the liquid is sprayed in all directions at 360 degrees.

The eco-friendly ultra-fine oxygen water injection system with the above configuration includes a digging process, a pipe installation process, a tubular support arrangement process, a floor nozzle installation process, a basic concrete pouring process, and an asphalt paving and painting process. It is constructed using a construction method.

In the digging process, digging is performed on a designated section of the roadside or road surface to form a passage for burying pipes.

In the pipe installation process, the pipe 111 is installed along the passage for burying the pipe.

In the tubular support arrangement process, the tubular support 50 is placed at each designated point of the pipe 111, and a high-pressure hose is connected to the pipe 111 to enter the tubular support 50. The end of the high pressure hose is connected to the spray nozzle 120.

As described above, the injection nozzle 120 includes a base having a flat upper surface and a seating hole formed in the center, a nozzle block assembled to the lower surface of the base, and a disk-shaped valve assembled to the nozzle block to be disposed in the seating hole. Includes (V).

In the bottom nozzle installation process, the male thread of a nipple connected to the connecting hose is fastened to the female thread formed in the nozzle block, the base is placed on the top of the tubular support, and bolts are fastened to assemble.

In the basic concrete pouring process, basic concrete is poured into the pipe burial passage to fix the tubular support.

In the asphalt paving and painting process, asphalt is paved so that the upper surface of the floor nozzle is exposed to the outside, and then the lane is painted. The asphalt paving process is preferably performed so that the bottom nozzle is embedded in the road surface so that the upper surface is exposed to the outside and does not protrude above the road surface.

Figure 5 is a plan view showing an operation example of an eco-friendly road liquid injection system according to a preferred embodiment of the present invention.

The water storage tank 100, first oxygen generator 20, pump 104, control panel 106, etc. provided in the ultra-fine oxygen water injection system according to a preferred embodiment of the present invention are arranged in a designated area around the road. The pipe 111 is buried along the road's median divider or lane boundary, and the spray nozzle 120 is connected to a high-pressure hose branched from the pipe 111 and installed on the road surface.

As described above, the first oxygen generator 20 is disposed between the filter 10 and the storage tank 100 or is inserted into the storage tank 100 to increase the amount of dissolved oxygen in the water. The purified water can be transferred to the spray nozzle 120 via the pipe 111 and sprayed on the road surface as a clean road liquid or an anti-icing liquid.

The injection nozzle 120 may be placed, for example, near the center line of the road. The area near the center line of the road includes a hilly section where the surface shape of the road surface is designed to be relatively raised or convex compared to the surrounding area, and is designed to allow smooth drainage on both sides starting from the hilly section.

When a 360-degree spray-type bottom nozzle is adopted as the spray nozzle 120, a disk-shaped valve (V) slightly protrudes at the center of the upper surface of the 360-degree spray bottom nozzle, but when pressed by a vehicle tire, the disk is moved by a predetermined elastic member. Since the type valve (V) descends integrally with the nozzle block and goes below the surface of the road surface, it does not interfere with the operation of the vehicle and damage to the disc type valve (V) itself can also be prevented.

When liquid is supplied to the injection nozzle 120 through the pipe 111, the disc-shaped valve (V) is instantly pushed up to a determined height by the water pressure of the liquid, thereby closing the gap formed under the circular edge of the disc-shaped valve (V). The liquid is sprayed in all directions at 360 degrees, spraying the road surface in all directions. The liquid sprayed in all directions at 360 degrees flows over a wide area of the road surface, washing away fine dust and foreign substances, and is discharged into the drain through the drain 150 installed on the roadside.

When the water pressure of the liquid is released after the cleaning work on the road surface is completed, the disc-shaped valve (V) can be lowered and returned to its original position by its own weight, or can be easily lowered and returned by being pressed by an external force such as a vehicle tire, so that the The inflow of foreign substances can be prevented.

As described above, when the present invention is applied, the air, water, and soil environment around the road can be efficiently improved by using cleanly purified liquid with simple equipment and low cost as clean road water to be sprayed on the road or salt water for road snow removal and anti-icing. It can be improved.

Although the present invention has been described above with limited examples and drawings, the present invention is not limited thereto and can be understood by those skilled in the art within the scope of equivalents of the technical idea of the present invention. Of course, various modifications and variations are possible.
