Description

Technical Field

[0002] Salt pan salt production involves the natural evaporation of seawater or salt lake brine on large, flat mudflats to remove water and crystallize the salt. Salt pans are a source of chemical and food raw materials in my country. Currently, conventional salt pan brine evaporation relies entirely on passive evaporation, which depends entirely on natural conditions such as sunlight intensity, duration of exposure, and ambient temperature. This results in a slow evaporation rate, requires large salt pan areas, and requires long salt drying times, severely restricting the capacity expansion of salt production companies.

[0003] Salt production is one of the important basic industries. Traditional salt field production mainly relies on natural evaporation, which is inefficient and greatly affected by climate. In order to improve production efficiency, various methods of heating brine have been tried in the prior art, such as coal, gas or electric heating. However, these methods have problems such as high energy consumption, high cost, and environmental pollution. Moreover, when only simple heating pipes are used to heat the salt field brine, the uniformity of the heating of the salt field brine is poor, affecting the overall heating effect.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 11In an embodiment of the present invention, a salt field brine heating system includes a heating module 10, an aeration module 20 and a solar power supply module 30. The heating module 10 includes multiple groups of heat exchange components 101 for heating the salt field brine, and the multiple groups of heat exchange components 101 form a series and symmetrically distributed pipeline system in the salt field brine. The two groups of heat exchange components 101 located at the ends are connected to a heating component 102 for circulating hot water into the interior. The aeration module 20 includes an air supply component 201 arranged in series and passing through each group of heat exchange components 101. The air supply component 201 is located at the center of each group of heat exchange components 101 and is downwardly connected to a support base 11. Aeration components 202 connected to the air supply component 201 and located directly below the heat exchange component 101 can be detachably installed on both sides of the support base 11. The solar power supply module 30 is used to convert solar energy into electrical energy and provide a sustainable power supply for the heating component 102 and the air supply component 201.

[0039] When the salt field brine heating system is actually used, the combined heating module 10 and aeration module 20 pipelines are evenly laid out in the salt field brine. The support base 11 provides a stable bottom support for the pipeline system in the salt field. The solar power supply module 30 installed around the salt field provides clean energy for the heating module 10 and the aeration module 20. A circulatory closed loop is formed between the heating component 102 and the heat exchange component 101. The liquid heated in the heating component 102 is transported to the heat exchange component 101 to heat the salt field brine. Renewable clean energy is used to provide electricity for salt field heating, which helps to reduce energy consumption and environmental pollution.

[0040] While the salt pan brine is being heated by the heat exchange component 101, the air supply component 201 and the aeration component 202 connected to its pipeline operate simultaneously. The gas transported in the air supply component 201 can be heated by the heat exchange component 101, thereby increasing the temperature of the gas finally output by the aeration component 202, which is beneficial to further improve the heating efficiency of the salt pan brine. At the same time, it can also increase the dissolved oxygen in the water, promote chemical reactions and microbial activities in the brine, and contribute to the decomposition of impurities and the oxidation of organic matter. The aeration component 202 sprays airflow onto the surface of the heat exchange component 101 at its top, stirring the water flow around the heat exchange component 101, which can effectively promote the uniformity of the overall heating of the salt pan brine, improve the heating and evaporation efficiency of the salt pan brine, and effectively reduce scaling on the outer surface of the heat exchange component 101.

[0041] Furthermore, the aeration module 20 also includes a rotating part 203 installed in the support base 11 and used to control the synchronous rotation of the aeration components 202 on both sides. Both sides of the support base 11 are fixedly installed with mounting brackets 204 that provide rotation support for the aeration components 202, and the mounting brackets 204 are provided with an upward opening for the airflow of the aeration components 202 to overflow. The air supply component 201 provides rotation support for the rotating part 203 extending above the heat exchange component 101.

[0042] The mounting bracket 204 can provide rotational support for the aeration component 202 while also limiting the direction of the aeration jet. Concentrating the airflow ejected by the aeration component 202 upward is conducive to further accelerating the liquid flow speed around the heat exchange component 101 and reducing the scaling speed on the surface of the heat exchange component 101. When the upward exhaust port of the aeration component 202 is blocked, the staff can rotate the rotating part 203, and the rotating part 203 drives the aeration component 202 to rotate inside the mounting bracket 204, turning the air outlet on the other side to an upward position for use, which can ensure the normal operation of the aeration component 202, thereby improving the overall operation stability of the device. The mounting bracket 204 also facilitates the rapid replacement of damaged aeration components 202.

[0043] In one embodiment, see Figures 1 to 3 Specifically, the air supply component 201 includes multiple groups of straight ventilation pipes 2011 that pass through the heat exchange component 101. Adjacent straight ventilation pipes 2011 are connected in series through connecting elbows 2012 or connecting straight pipes 2013. A sealing plate 2014 is fixedly installed at the end of one group of straight ventilation pipes 2011 arranged in series, and one group of straight ventilation pipes 2011 is connected to a blower 2015 at the end through an air supply pipe 2016 connected by a flange.

[0044] When the blower 2015 is running, it can transport gas to the connected ventilation straight pipe 2011, the connecting elbow 2012 and the connecting straight pipe 2013. The gas can be heated when flowing through the ventilation straight pipe 2011 located inside the heat exchange component 101. The ventilation straight pipe 2011 transports the gas to each group of aeration components 202 and then sprays it into the salt field brine, thereby achieving the effect of efficiently heating and aerating the salt field brine. The ventilation straight pipe 2011 can be made of a metal pipe with good thermal conductivity, etc., and the connecting elbow 2012 and the connecting straight pipe 2013 can be made of a plastic material that is not easy to conduct heat, is low in cost and is corrosion-resistant. The connections between the pipes can be sealed with flanges.

[0045] See Figures 2 to 8 Among them, the center of the ventilation straight pipe 2011 is connected to one end of the three-way pipe 13 fixedly installed in the support seat 11 through a flange through a downward-facing butt joint 12. The provided butt joint 12 and three-way pipe 13 facilitate the communication between the aeration components 202 on both sides of the support seat 11 and the inner cavity of the ventilation straight pipe 2011. The center of the ventilation straight pipe 2011 is sealed and rotatably connected to the rotating part 203 through an upward-facing support pipe 14. A support ring 15 is welded to the top of the support pipe 14. The outer ring of the support ring 15 is provided with multiple groups of positioning holes 16 that are compatible with the rotating part 203. The provided support ring 15 and support pipe 14 can provide stable rotation support and rotation limit for the rotating part 203.

[0046] Based on the above embodiments, see Figures 2 to 10 Specifically, the rotating member 203 includes a first rotating rod 2031 that is sealed and rotatably connected to the bottom of the tee pipe 13. The sealed rotating connection can refer to the sealing structure design of the rotating connection of components such as valves in the prior art. It is a prior art and is not described in detail here. The first rotating rod 2031 extends to the end below the tee pipe 13 and is fixedly installed with a first bevel gear 2032. Both sides of the support seat 11 are rotatably installed with a sealing clip to the rotating tube 2033 on the end of the tee pipe 13. The rotating tube 2033 is snap-connected to the aeration assembly 202. The rotating tube 2033 is fixedly installed with a first bevel gear. The second bevel gear 2034 is meshed with the wheel 2032, and the internal sealing rotation of the support tube 14 is connected to the second rotating rod 2035. The bottom end of the second rotating rod 2035 is in the shape of a cross rod that is compatible with the cross groove 17 opened at the top of the first rotating rod 2031. The top of the second rotating rod 2035 is welded with a shift rod 2036 with a slide groove 18 opened inside. The inside of the slide groove 18 is connected to a slide plate 2038 through a spring 2037. The side of the slide plate 2038 is fixedly installed with a hook 2039 that slides and extends to the outside of the slide groove 18. One end of the hook 2039 slides and is embedded in the inside of one group of positioning holes 16.

[0047] When a part of the aeration assembly 202 is clogged after being used for a long time, the staff can move the slide plate 2038 on the top to slide inside the slide groove 18. The slide plate 2038 drives the spring 2037 to retract and the hook 2039 to move. After the hook 2039 moves to the outside of the positioning hole 16, the lever 2036 is rotated to drive the second rotating rod 2035 to rotate. The bottom end of the second rotating rod 2035 that slides and buckles to the inside of the cross groove 17 can drive the first rotating rod 2031 to rotate. The first rotating rod 2031 can drive the first bevel gear 2032 to rotate. The rotating first bevel gear 2032 drives the second bevel gears 2034 on both sides to rotate synchronously. The second bevel gear 2034 drives The rotating tube 2033 rotates, and the rotating tube 2033 drives the aeration assembly 202 connected thereto to rotate inside the mounting bracket 204. After the aeration assembly 202 is adjusted to the corresponding position, the hook 2039 is embedded in the corresponding positioning hole 16 through the reset of the spring 2037, thereby realizing the positioning of the rotating rod. After the adjustment, the blocked part of the aeration assembly 202 is rotated into the mounting bracket 204, and the air holes of the unused aeration assembly 202 are turned upward to facilitate the normal operation of the aeration assembly 202. The outer ring of the aeration assembly 202 is divided into different equal parts and used separately, which can increase the aeration speed and also increase the actual service life of the aeration assembly 202.

[0048] See Figures 2 to 11Specifically, the aeration assembly 202 includes an aeration tube 2021 connected to the rotating tube 2033. The open end of the aeration tube 2021 is clamped with the end of the rotating tube 2033 through an integrally formed first clamping block 2022, and the closed end of the aeration tube 2021 is clamped with the mounting bracket 204 through an integrally formed second clamping block 2023. The outer ring of the aeration tube 2021 is provided with multiple rows of aeration holes 19 distributed equidistantly around the central axis. Only a few rows of aeration holes 19 are shown in the figure. In actual application of the device, the corresponding number of aeration holes 19 can be increased according to actual needs. The aeration holes 19 and the outer ring of the aeration tube 2021 are fixedly installed with an aeration membrane 2024 that fits the inner wall of the mounting bracket 204. The straight ventilation pipe 2011 transports gas to the aeration tube 2021 through the docking tube 12, the tee pipe 13 and the rotating tube 2033. The gas inside the aeration tube 2021 is ejected into the salt field brine through the aeration holes 19 and the aeration membrane 2024. The multiple rows of aeration holes 19 on the outer ring of the aeration tube 2021 can be rotated and adjusted for use in batches, and the scale on the surface of the aeration membrane 2024 that fits the inner wall of the mounting bracket 204 can also be removed.

[0049] Correspondingly, the mounting bracket 204 includes a top open bracket tube 2041 fixedly mounted on the side of the support seat 11, the inner wall of the bracket tube 2041 fits with the outer surface of the aeration membrane 2024, and a cylinder 2042 and a threaded tube 2043 are fixedly mounted on one end of the bracket tube 2041. A turntable 2044 is fixedly mounted on the end of the cylinder 2042, and a clamping screw 2047 is threadedly connected to the center of the turntable 2044. The end of the clamping screw 2047 is rotatably mounted with a docking plate 2045 that is engaged with the second clamping block 2023. A positioning bolt 2046 that is threadedly connected to the inner cavity of the threaded tube 2043 slides through the interior of the turntable 2044.

[0050] When the second bevel gear 2034 drives the rotating tube 2033 to rotate, the rotating tube 2033 can drive the aeration tube 2021 to rotate through the first clamping block 2022 connected thereto, and the aeration tube 2021 can drive the docking plate 2045 to rotate at the end of the pressing screw 2047 through the second clamping block 2023. When the damaged aeration component 202 needs to be replaced, the staff rotates the pressing screw 2047 to drive the docking plate 2045 at its end to move left and right, and moves the docking plate 2045 to the left. After reaching the outside of the bracket tube 2041, rotate the positioning bolt 2046 to the outside of the threaded tube 2043, and the turntable 2044 rotates with the cylinder 2042 as the support point. After the turntable 2044 rotates to the outside of the end of the bracket tube 2041, replace the new aeration component 202 and fix the positioning bolt 2046 into the threaded tube 2043. Rotate the tightening screw 2047 to press the docking plate 2045 to the end of the aeration component 202, so that the aeration component 202 can be quickly assembled, disassembled and replaced.

[0051] In one embodiment, see Figures 1 to 9 Specifically, the heat exchange component 101 includes a heat exchange tube 1011 welded to the outer surface of the ventilation straight pipe 2011 at both ends, and the heat exchange tube 1011 is welded to the outer ring of the support tube 14 and the docking tube 12. Two groups of delivery pipes 1012 are welded to the outer ring of the heat exchange tube 1011 near its two ends. Adjacent heat exchange tubes 1011 are connected through the delivery pipes 1012. The two groups of heat exchange tubes 1011 close to the heating component 102 are connected to it through the delivery pipes 1012. The delivery pipes 1012 on the two groups of heat exchange tubes 1011 away from the heating component 102 are connected by a series pipe 1013. Each group of heat exchange tubes 1011 is welded with two groups of upper and lower heat conduction plates 1014 located directly above the aeration component 202. The connection between the pipes can be sealed and docked using flanges commonly used in the prior art.

[0052] The hot water provided by the heating component 102 is circulated and transported to multiple groups of heat exchange tubes 1011, delivery pipes 1012 and series pipes 1013 connected in series. The pipe fittings can heat the salt field brine and the gas in the ventilation straight pipe 2011 at the center of the heat exchange tube 1011 together. The heat exchange tube 1011, delivery pipe 1012, series pipe 1013 and heat conduction plate 1014 can all be made of alloy materials with good thermal conductivity and corrosion resistance. The heat conduction plate 1014 provided on the heat exchange tube 1011 can help speed up the heat transfer in the pipe fitting to the salt field brine, thereby improving the heating efficiency of the salt field brine. The airflow ejected upward by the aeration component 202 can cover the outer surface of the heat exchange tube 1011 and the heat conduction plate 1014, which can effectively reduce scaling on the surface of the heat exchange tube 1011 and the heat conduction plate 1014, and also help reduce the corrosion rate of the heat exchange tube 1011 and the heat conduction plate 1014.

[0053] Correspondingly, the heating component 102 includes a first connecting pipe 1021 connected to the delivery pipe 1012 on one group of heat exchange tubes 1011, the first connecting pipe 1021 is connected to the solar electric heating module 30, the solar electric heating module 30 is connected to the circulation pump 1024 through the second connecting pipe 1023, the circulation pump 1024 is connected to the delivery pipe 1012 on one group of heat exchange tubes 1011 through the third connecting pipe 1025, the solar electric heating module 30 heats the liquid used for heat exchange, the circulation pump 1024 pumps the liquid heated by the solar electric heating module 30 into the heat exchange component 101 through the third connecting pipe 1025 and the second connecting pipe 1023 for circulation, and the liquid after heat exchange in the heat exchange component 101 can be circulated again to the solar electric heating module 30 through the first connecting pipe 1021 for reheating and use.

[0054] In one embodiment, see Figure 1Specifically, the solar power supply module 30 includes a photovoltaic heating component 301 that converts solar energy into electrical energy. The output end of the photovoltaic heating component 301 is connected to a controller 302, and the controller 302 is connected to a battery 303 and an inverter 304. The inverter 304 is used to convert the direct current stored in the battery 303 into alternating current for use in the circulation pump 1024, the blower 2015 and the solar electric heating module. A distribution box can also be assembled at the output end of the inverter 304 to supply power to the terminal equipment. The use of solar energy to heat the salt field brine can effectively avoid environmental problems caused by heating the salt field brine. The models of equipment such as the circulation pump 1024, the blower 2015 and the solar electric heating module, as well as the size and material of each pipe fitting, can be selected from common types in the prior art according to the environment and size of the salt field.
