Description

Technical Field

[0001] The present invention belongs to the technical field of seawater atomization measurement, and particularly relates to a front-end atomization device suitable for measuring dissolved gases in seawater. Background Art

[0002] In addition to inorganic salts and organic matters, seawater inevitably contains some components of the atmosphere dissolved in it due to the contact between its surface and the atmosphere. These gases are constantly exchanged between the ocean and the atmosphere, and there is a dynamic balance. Some gases in seawater participate in biological and chemical reactions, such as carbon dioxide, oxygen, etc., and the other part that does not participate in the reaction is called conservative gas. "Blue carbon" is the process, activity and mechanism of using marine activities and marine organisms to absorb carbon dioxide in the atmosphere, and fix and store it in the ocean. To carry out this activity, it is necessary to measure the dissolved carbon dioxide gas in seawater.

[0003] The measurement of carbon dioxide gas in seawater requires long-term continuous observation to ensure the authenticity and effectiveness of the data. The measurement work is mostly achieved through ship-based underway surveys, buoy fixed-point surveys, etc. When measuring, it is necessary to conduct preliminary filtration, atomization, water-vapor separation and drying of seawater. However, seawater contains a lot of impurities and high salinity. The existing devices for detecting dissolved gases in seawater are slow and inefficient in the process of water droplet atomization, and the evaporated salts and solid particles are easy to block the transmission pipeline, and long-term reliable measurement cannot be achieved.

[0004] The US patent No. US15634043 discloses a method and device for separating steam from gas, including an exchanger, a droplet generating device located at the top of the exchanger, and a bubbling device located at the bottom of the exchanger. The exchanger is provided with a steam inlet. The gas entering the steam inlet forms bubbles in the liquid at the bottom of the exchanger through the bubbling device, so that a part of the steam exchanges energy with the bubbles and generates target droplets. The fine droplets formed by the droplet generating device at the top drop onto the intermediate gas, exchange heat with the steam contained in the intermediate gas, and generate bottom liquid that accumulates and is collected at the bottom. The droplet generating device includes a plurality of nozzles, a drip tray and a perforated plate; the bubbling device includes a plurality of bubbling trays, a bubbling plate, a bubble cap, an ejector and a nozzle. The invention provides a good temperature gradient for spraying, and also has high heat flux density and space efficiency. However, the following technical problems need to be improved when the invention scheme works: there will be solid particles or crystal residues after liquid evaporation, which are easy to cause blockage of some channels or pipe fittings; the formed droplets are at different intervals from the center, which is easy to cause uneven heating and affect the heat exchange stability of the bottom liquid. Summary of the Invention

[0005] The purpose of the present invention is to provide a front-end atomization device suitable for measuring dissolved gases in seawater, which has low energy consumption and can atomize seawater safely, stably, efficiently and with high quality.

[0006] The technical solution adopted by the present invention to achieve the above object is as follows:

[0007] A front-end atomization device applicable to measuring dissolved gases in seawater, comprising: an atomizer, the atomizer includes an atomization chamber, a liquid inlet and a gas outlet are respectively opened on the side and top of the atomization chamber, a heating device is provided at the bottom inside the atomization chamber, and an inner chamber communicating with the gas outlet is provided inside the atomization chamber. Seawater is conveyed into the atomization chamber through the liquid inlet, the seawater in the atomization chamber is boiled to form water vapor by the heating device, the water vapor floats upward due to its density being less than the air density in the atomization chamber, and is condensed into water mist during the process of passing through the inner chamber, and the water mist flows out from the gas outlet for subsequent collection and drying and other operations.

[0008] Preferably, a drain pipe is further provided inside the atomization chamber. The drain pipe includes a straight pipe connected to one end of the liquid inlet, the straight pipe communicates with an annular pipe sleeved outside the inner chamber, and a plurality of nozzles are opened below the annular pipe. The other end of the liquid inlet is connected to a pump body. When the water body in the atomization chamber is heated to boiling by the heating device, the wall temperatures of the atomization chamber and the inner chamber increase. The design of the annular pipe and the nozzles enables the sprayed water body to evenly contact the atomization chamber and the inner chamber on the one hand, realizing the preliminary heating of the sprayed water body, which is beneficial to improving the rate of boiling of the water body to form water vapor. On the other hand, it reduces the impact of the water body on the heating device at the bottom of the atomization chamber, ensures the stable and efficient evaporation and atomization of the device, reduces the maintenance cost. At the same time, the contact between the water body and the inner chamber can achieve heat exchange, thereby reducing the heat of the inner chamber wall, increasing the probability of the steam condensing into water mist when passing through the inner chamber, and being beneficial to improving the accuracy of data measurement.

[0009] Preferably, a partition plate is fixed to the inner wall of the bottom of the atomization chamber, and the partition plate is provided with sieve holes in an array. The water body entering the inside of the atomization chamber still carries fine particles after preliminary filtration, and its salts precipitate to form crystals after the seawater evaporates completely. The fine particles and crystals can be collected below the partition plate through the sieve holes for centralized cleaning.

[0010] Preferably, the partition plate is connected with a rotating member. The rotating member includes a bearing installed at the center of the partition plate, a rotating sleeve is fixed inside the bearing inner ring, and blades are circumferentially connected to the outside of the rotating sleeve. When the heating component heats the water body, fine bubbles floating upward are formed in the water and act on the blades, causing the plurality of blades to drive the rotating sleeve to rotate axially relative to the partition plate and form a swirling flow. On the one hand, a low pressure is formed at the center of the water body swirling flow, which can reduce the boiling point of the water, being beneficial to the subsequent injected water body boiling again quickly, saving energy consumption. On the other hand, the swirling flow causes the circulating flow of the heated water body, improving the heat conduction effect of the water body, being beneficial to shortening the boiling time and further reducing the energy consumption of the heating device.

[0011] Preferably, a flow guide sleeve is fixed inside the rotating sleeve. The flow guide sleeve is a conical sleeve. The large port of the conical sleeve is adjacent to the partition board, and the small port of the conical sleeve is adjacent to the gas outlet. The flow guide sleeve realizes the heat exchange of the water bodies above and below the partition board, ensuring the boiling of the water body. The boiling of the water body causes a large number of rising bubbles to be generated in the bottom water body. Some of the bubbles flow upward to the center through the flow guide sleeve, which is conducive to the concentrated flow of the water vapor formed after the bubbles burst upward into the inner chamber above and condensing, improving the collection rate of the fog. Moreover, the rotation of the blades causes the bottom water body to flow upward and pass through the flow guide sleeve. The water body passing through the flow guide sleeve is accelerated due to the constriction of its top opening, forming a low pressure at the position of the flow guide sleeve, improving the low pressure effect at the center of the swirl formed by the blades, and further reducing the power consumption of the heating device by lowering the boiling point.

[0012] Preferably, baffles are symmetrically fixed to the lower outer side of the rotating sleeve. The baffles are provided with through grooves, and rollers are rotatably arranged in the through grooves. When the blades drive the rotating sleeve to rotate, the baffles are driven to rotate. At the same time, the rollers rotating in the baffles contact the partition board and roll axially, realizing the scraping and extrusion of the fine impurities and salt crystals on the upper surface of the partition board, so that they fall below the partition board through the sieve holes, which is conducive to preventing the partition board from being blocked and affecting the water body heat exchange. Moreover, the rolling contact of the rollers does not form scratches with the partition board, avoiding wear and improving the service life.

[0013] Preferably, an auxiliary atomization member is arranged inside the inner chamber. The auxiliary atomization member includes a first mesh plate fixed to the inner wall of the inner chamber. A second mesh plate and a connecting component are arranged below the first mesh plate. The second mesh plate is connected to the first mesh plate through the connecting component. The water vapor entering the inner chamber passes through the first mesh plate and the second mesh plate successively, which helps to increase the probability of the water vapor condensing into fog when encountering the wire meshes, improving the fog collection speed.

[0014] Preferably, the connecting component includes a base body fixed to the center of the bottom of the first mesh plate. A guide rod is fixed downward from the base body, and a clamping plate is fixed to the lower end of the guide rod. A rod sleeve sleeved on the guide rod is fixed at the center of the second mesh plate. The continuously formed water vapor condenses into water droplets in the mesh holes of the first mesh plate and the second mesh plate and forms a water film attached to the first mesh plate and the second mesh plate, reducing the upward flow rate of the water mist. At this time, the accumulation of the water vapor below the second mesh plate increases the air pressure, pushing the second mesh plate to drive the rod sleeve to slide upward relative to the guide rod. When the sliding stops, the second mesh plate causes vibration and transmits it to the first mesh plate through the inner chamber, causing the condensed water droplets attached to the first mesh plate, the second mesh plate and the inner chamber to fall off, which is conducive to the water body dripping to the bottom and evaporating and atomizing again, improving the data accuracy of the gas content measurement. The clamping plate limits the downward sliding distance of the rod sleeve on the guide rod, preventing it from falling off and ensuring that the baffle plate is in an inclined state to form fog diversion.

[0015] Preferably, an adjusting component is disposed around the side of the connecting component. The adjusting component includes a connecting rod and a flow guide plate. One end of the connecting rod is hinged to a rod sleeve, and the other end is hinged to the flow guide plate. One end of the flow guide plate is hinged to the base body, and the other end can swing freely. When the second mesh plate drives the rod sleeve to slide upward, it synchronously drives the connecting rod to slide upward and swing at the hinge with the rod sleeve, causing the flow guide plate to swing upward at the hinge with the base body. On the one hand, the swinging flow guide plate drives the surrounding air flow, reducing the temperature of the inner chamber and promoting the formation of fog. On the other hand, the flow guide plate relatively blocks the first mesh plate, reducing the outflow rate from the air outlet, preventing the water vapor from flowing out at too fast a rate and causing deviation of the measured data in a state where it is not condensed into fog.

[0016] Preferably, a pressure relief valve is horizontally connected to the side of the bottom of the atomization chamber, and a drain port is connected below the center of the bottom of the atomization chamber. A temperature sensor and a pressure sensor are also provided in the atomization chamber. The temperature sensor and the pressure sensor respectively detect the temperature and pressure in the atomization chamber in real time and transmit data. Due to heating, high pressure is formed in the atomization chamber. After evaporation ends, the drain port is opened to communicate with the outside. Affected by the air pressure, the residues and crystals inside are quickly discharged along with the remaining water body, reducing the probability of internal blockage during long-term use and simplifying the cleaning work. When the water flow rate injected into the atomization chamber is too fast and the evaporation efficiency is insufficient, the water level in the atomization chamber will rise rapidly. When the water surface contacts the flow guide plate, the flow guide plate swings at the hinge under the action of water pressure, realizing the closing of the flow guide plate below the first mesh plate to prevent the water body from carrying impurities and discharging from the air outlet, causing a malfunction of the connected measuring machine. At the same time, after the flow guide plate is closed, the atomization chamber is airtight and the air pressure increases. At this time, the pressure sensor will detect and transmit a warning pressure value outward to remind the personnel that the internal pressure is too high and stop water injection to avoid losses caused by device damage.

[0017] Since the atomization chamber with an internal partition and a rotating member is used in the present invention to atomize seawater evaporation, the following beneficial effects are obtained: The design of the drain pipe enables seawater to be evenly sprayed and fully contact with the atomization chamber and the inner chamber for heat exchange, which is beneficial to the initial heat addition of the water body to accelerate evaporation and is also beneficial to the cooling of the inner chamber to condense water vapor; The rotating member is affected by the heated water body to make the blades rotate, forming a swirling flow with a central low pressure to reduce the boiling point and reduce the energy consumption of the heating device; The blades stir the water body to accelerate heat transfer, speed up the boiling speed, and improve the atomization efficiency; The flow guide sleeve guides the boiling rising bubbles, enabling the steam to be concentratedly discharged and improving the fog collection efficiency; The rotating member drives the baffle to rotate to scrape the crystal particles on the partition to prevent blockage and affect heat exchange; The auxiliary atomization member improves the probability of liquid droplet generation and redripping through the relative displacement of the first mesh plate and the second mesh plate, improving the cleanliness of the atomized gas and being beneficial to enhancing the accuracy of the measured data; When the internal water injection is too fast, the water pressure acts on the flow guide plate to close it, and cooperate with the pressure sensor to give an alarm to prevent the water body from entering the measuring device, causing a malfunction and triggering a high-pressure explosion. Therefore, the present invention is a front-end atomization device for measuring dissolved gases in seawater that is low in energy consumption and can safely, stably, efficiently, and high-quality atomize seawater.

Detailed Description of the Preferred Embodiments

[0028] The technical solutions of the present invention will be further described in detail below in conjunction with the specific embodiments and the drawings:

[0029] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] See attached Figure 1 - attached Figure 2, A front-end atomization device suitable for measuring dissolved gases in seawater, including an atomization chamber 1. An inlet 10 and an air outlet 11 are respectively arranged on the side and top of the atomization chamber 1. A heating device 12 is provided at the bottom inside the atomization chamber 1, and an inner chamber 2 communicating with the air outlet 11 is arranged inside the atomization chamber 1. The inner chamber 2 is a hollow sleeve. The top of the inner chamber 2 communicates with the bottom end of the air outlet 11 inside the atomization chamber 1. The inner chamber 2 and the atomization chamber 1 are coaxially arranged and a partition layer is formed between them, and this partition layer communicates with the inlet 10.

[0031] The preliminarily filtered seawater is transported to the inside of the atomization chamber 1 through the inlet 10. The seawater inside the atomization chamber 1 is boiled by the heating device 12 to form water vapor. Because the density of the water vapor is less than the density of the air inside the atomization chamber 1, it floats upward. The floating water vapor can be discharged outward through the inner chamber 2 to the air outlet 11, and condenses into water mist during the process of passing through the inner chamber 2. The water mist flows out from the air outlet 11 for subsequent operations such as water-vapor balance and drying.

[0032] See the appendix Figure 3 , A drain pipe 3 is also arranged inside the atomization chamber 1. The drain pipe 3 includes a straight pipe 30 connected to one end of the inlet 10. The straight pipe 30 is connected to an annular pipe 31 sleeved outside the inner chamber 2. A plurality of nozzles 32 are arranged below the annular pipe 31. The other end of the inlet 10 is connected to a pump body. The filtered seawater is transported to the straight pipe 30 fixed at the inlet 10 through the pump body and continuously flows to each nozzle 32 of the annular pipe 31 and sprays downward.

[0033] When the water body inside the atomization chamber 1 is heated by the heating device 12, the wall temperatures of the atomization chamber 1 and the inner chamber 2 increase. The design of the annular pipe 31 and the nozzles 32 enables the sprayed water body to evenly contact the atomization chamber 1 and the inner chamber 2 on one hand, realizing the preliminary heating of the sprayed water body, which is beneficial to improving the rate of water body boiling to form water vapor. On the other hand, it reduces the impact of the water body on the heating device 12 at the bottom of the atomization chamber 1, maintains the evaporation and atomization of the injected seawater by the heating device 12, and at the same time reduces the maintenance cost of the heating device 12. The low-temperature water body sprayed from the nozzles 32 can exchange heat with the inner chamber 2, thereby reducing the heat of the inner chamber 2 wall, increasing the probability of water vapor condensing into water mist when passing through the inner chamber 2, improving the fog formation efficiency, and being beneficial to improving the accuracy of subsequent data measurement.

[0034] See the appendix Figure 4 , A partition plate 4 is fixed on the inner wall at the bottom of the atomization chamber 1. The partition plate 4 is arranged with sieve holes 40 in an array. The water body entering the inside of the atomization chamber 1 still carries fine particles after preliminary filtration, and its salts precipitate to form crystals after the seawater evaporates completely. The fine particles and crystals can be collected below the partition plate 4 through the sieve holes 40 for convenient centralized cleaning.

[0035] See the appendix Figure 5, a partition plate 4 is connected with a rotating member 5. The rotating member 5 includes a bearing 50 installed at the center of the partition plate 4. The outer ring of the bearing 50 is fixed to the partition plate 4, and a rotating sleeve 51 is fixed to the inner ring of the bearing 50. Blades 52 are circumferentially connected to the outer side of the rotating sleeve 51. The blades 52 are arranged obliquely relative to the axis of the rotating sleeve 51. The rotating sleeve 51 can drive the blades 52 to rotate relative to the partition plate 4.

[0036] When the heating component heats the water body, fine bubbles that float upward are formed in the water and act on the blades 52, causing the multiple blades 52 to drive the rotating sleeve 51 to axially rotate relative to the partition plate 4 and form a swirling flow. On the one hand, a low pressure is formed at the center of the swirling flow of the water body, which can reduce the boiling point of the water, facilitating the subsequent injected water body to boil again quickly, reducing the energy consumption of the heating device 12. On the other hand, the swirling flow causes the circulating flow of the heated water body, improving the heat conduction effect of the water body, facilitating the shortening of the boiling time, increasing the steam generation rate, and further reducing the energy consumption of the heating device 12.

[0037] A flow guiding sleeve 53 is fixed inside the rotating sleeve 51. The flow guiding sleeve 53 is a conical sleeve. The large port of the conical sleeve is adjacent to the partition plate 4, and the small port of the conical sleeve is adjacent to the gas outlet 11.

[0038] When the water body boils, a large number of rising bubbles are generated at the bottom of the water body. Some bubbles flow upward from the bottom large port of the flow guiding sleeve 53 to the center and pass through its small port, which is conducive to the concentrated inflow and condensation of the water vapor formed after the bubbles burst into the upper inner chamber 2, improving the collection rate of the mist. Moreover, the rotation of the blades 52 causes the bottom water body to flow upward and pass through the flow guiding sleeve 53. The water body passing through the flow guiding sleeve 53 is accelerated due to the constriction of its top opening, forming a low pressure at the position of the flow guiding sleeve 53, improving the low pressure effect at the center of the swirling flow formed by the blades 52, and further reducing the power consumption of the heating device by reducing the boiling point.

[0039] See Appendix Figure 6 , symmetrically fixed to the outer side and lower part of the rotating sleeve 51 are baffles 54. Through slots 55 are formed in the baffles 54, and rollers 56 are rotatably arranged in the through slots 55. The axial direction of the rollers 56 is parallel to the long side direction of the through slots 55.

[0040] When the blades 52 drive the rotating sleeve 51 to rotate, the baffles 54 are driven to rotate. At the same time, the rollers 56 rotating in the baffles 54 contact and axially roll on the partition plate 4, realizing the scraping and extrusion of fine impurities and salt crystals on the upper surface of the partition plate 4, enabling them to fall through the sieve holes 40 below the partition plate 4. This is conducive to preventing the blockage of the partition plate 4 from affecting the heat exchange of the water body, and the rolling contact of the rollers 56 does not form scratches with the partition plate 4, avoiding the wear of the partition plate 4 and increasing the service life.

[0041] See Appendix Figure 7 - Appendix Figure 8, an auxiliary atomizing member 6 is provided in the inner chamber 2. The auxiliary atomizing member 6 includes a first mesh plate 61 fixed to the inner wall of the inner chamber 2. A second mesh plate 62 and a connecting component 7 are provided below the first mesh plate 61. The second mesh plate 62 is connected to the first mesh plate 61 through the connecting component 7. The water vapor entering the inner chamber 2 passes through the first mesh plate 61 and the second mesh plate 62 successively, which helps to increase the probability of the water vapor condensing into fog when encountering the wire mesh and improve the fog collection speed.

[0042] The connecting component 7 includes a base body 70 fixed to the center of the bottom of the first mesh plate 61. A guide rod 71 is fixed downward from the base body 70. A clamping plate 72 is fixed to the lower end of the guide rod 71. A rod sleeve 73 sleeved on the guide rod 71 is fixed at the center of the second mesh plate 62. The second mesh plate 62 can axially slide relative to the first mesh plate 61. The continuously formed water vapor condenses into water droplets in the mesh holes of the first mesh plate 61 and the second mesh plate 62 and forms a water film attached to the first mesh plate 61 and the second mesh plate 62, reducing the upward flow rate of the water mist. At this time, the water vapor below the second mesh plate 62 accumulates to increase the air pressure, pushing the second mesh plate 62 to drive the rod sleeve 73 to slide upward relative to the guide rod 71. When the sliding stops, the second mesh plate 62 causes vibration and transmits it to the first mesh plate 61 through the inner chamber 2, causing the condensed water droplets attached to the first mesh plate 61, the second mesh plate 62 and the inner chamber 2 to fall off, which is beneficial to the water droplets dripping to the bottom and evaporating and atomizing again, improving the data accuracy of gas content measurement.

[0043] An adjusting component 8 is arranged around the side of the connecting component 7. The adjusting component 8 includes a connecting rod 80 and a guide vane 81. One end of the connecting rod 80 is hinged to the rod sleeve 73, and the other end is hinged to the guide vane 81. One end of the guide vane 81 is hinged to the base body 70, and the other end can swing freely. A conical protrusion is arranged in an array on the side of the guide vane 81 close to the first mesh plate 61. The second mesh plate 62 drives the rod sleeve 73 to slide upward and synchronously drives the connecting rod 80 to slide upward and swing at the hinge with the rod sleeve 73, causing the guide vane 81 to swing upward at the hinge with the base body 70. On the one hand, the swinging guide vane 81 drives the surrounding air flow to reduce the temperature of the inner chamber 2 and promote the formation of fog. On the other hand, the guide vane 81 relatively blocks the first mesh plate 61, reducing the outflow rate from the air inlet 11 and preventing the water vapor from flowing out too fast in a state where it is not condensed into fog, causing deviation of the measured data.

[0044] The atomization chamber 1 is horizontally connected with a pressure relief valve 13 on the lateral side of the bottom. The atomization chamber 1 is connected with a drain port 14 below the center of the bottom. A temperature sensor 15 capable of transmitting data externally and a pressure sensor 16 are also arranged in the atomization chamber 1. The temperature sensor 15 and the pressure sensor 16 respectively detect the temperature and pressure in the atomization chamber 1 in real time and transmit data. When the air pressure is too high, the pressure relief valve 13 is opened to release some of the water body and gas inside, preventing the atomization chamber 1 from bursting due to high pressure. After evaporation, the drain port 14 is opened. Due to heating, high pressure is formed in the atomization chamber 1. Affected by the air pressure, the residues and crystals inside are quickly discharged along with the residual water body, reducing the probability of internal blockage during long-term use and simplifying the cleaning work.

[0045] When the water body flow rate injected into the atomization chamber 1 is too fast and the evaporation efficiency is insufficient, the water body in the atomization chamber 1 will quickly rise. When the water surface contacts the guide plate 81, the guide plate 81 swings at the hinge under the action of water pressure, realizing the closing of the guide plate 81 below the first mesh plate 61, so as to prevent the water body from carrying impurities and discharging from the air outlet 11, causing faults in the connected measuring machine. At the same time, after the guide plate 81 is closed, the atomization chamber 1 is airtight and the air pressure rises. At this time, the pressure sensor 16 will detect and transmit the warning pressure value externally, reminding the personnel that the internal pressure is too high to stop water injection and avoiding losses caused by device damage.

[0046] The atomization chamber 1 is sequentially connected with a water vapor balancer, a dryer, and a carbon dioxide detector through the output port. The atomization chamber 1, the water vapor balancer, the dryer, and the carbon dioxide detector are assembled to form a seawater measuring device and are arranged on a sailing ship. At the same time, a data transmission system connected to the measuring device is also set on the sailing ship.

[0047] See Appendix Figure 9 , the data transmission system includes a data acquisition system 90, an underwater communication system 91, a core buoy system 92, and a display and control system 93.

[0048] The data acquisition system 90 is used to collect different types of marine data information through multiple sensors and transmit the collected information to the underwater communication system 91 by using underwater communication technology. The data acquisition system 90 includes: a coordinate sensor, a flow sensor, a water temperature sensor, a water depth sensor, and a seawater measuring device;

[0049] The underwater communication system 91 is used to send the received data information to the core buoy system 92 by using underwater communication technology. The underwater communication system 91 includes a mobile communication node AUV and a fixed communication node mooring buoy;

[0050] The core buoy system 92 integrates and processes different types of marine environmental information through data fusion technology to obtain the values of seawater dissolved carbon dioxide content at different positions, different depths, and different regions. The core buoy system 92 includes a buoy, an underwater acoustic-optical communication unit, a satellite communication unit, and a signal processor;

[0051] The display and control system 93 is used to display the received monitoring data.
