Description

Technical Field

[0001] The present invention relates to the technical field of ceramic cultural relic desalination, and particularly to a marine-emerged ceramic desalination device. Background Art

[0002] As is well known, China's underwater cultural heritage is extremely rich. With the development of underwater archaeological work, a large number of precious ceramic cultural relics representing the characteristics of Chinese civilization have been salvaged and excavated from the water. After being soaked in seawater and acted upon by marine organisms and marine sediments for a long time, a hard concretion tightly cemented is formed on the surface of these ceramic cultural relics, and a large amount of marine salts are wrapped and bound. Soluble salt substances will penetrate into the cracks and pore structures of the loose fetal glaze and deposit. After emerging from the water, irreversible losses will be caused to the cultural relics due to temperature and humidity changes. Moreover, common insoluble salts such as rust and calcium-magnesium deposits attached to marine-emerged ceramics not only affect the appearance of the cultural relics but also cause continuous deterioration of the cultural relics during subsequent preservation and restoration processes. Therefore, it is very necessary to remove soluble salts from marine-emerged ceramic cultural relics.

[0003] Currently, the technologies for removing soluble salts from marine-emerged ceramic cultural relics mainly include the deionized water static immersion method, the hot water immersion acceleration method, the pulp pasting method, the ultrasonic acceleration method, the circulating water immersion method, and the electric field acceleration desalination method, etc. Among them, the heating immersion method mainly immerses the whole sample in heated deionized water, and the method of soaking and boiling and replacing the immersion liquid is used to achieve the purpose of removing soluble salts inside the sample; the pulp pasting method mainly uses the capillary action of the pulp attached to the surface of the cultural relic to transfer soluble salts from the inside of the utensil to the surface and crystallize; the ultrasonic and electric field acceleration methods mainly show that, according to existing data, the principles of ultrasonic oscillation and direct current electric field adsorption of cations and anions are used for desalting. The above methods generally have the disadvantages of being time-consuming, low in efficiency, and difficult to remove soluble salts inside ceramic cultural relics.

[0004] Research shows that for samples treated by traditional desalination technologies and reaching the desalination end point, the salt content inside is still very high, which indicates that the desalination technologies adopted can only remove soluble salts on the surface of the cultural relics; although means such as ultrasonic and heating can accelerate the diffusion of salt ions in the immersion water body, the migration of soluble salts inside the ceramic to the surface is the rate-limiting step of the desalination rate and is not suitable in specific fields such as ceramics; the electric field helps the diffusion of ions, but its polarization effect on water makes it difficult to truly achieve continuous operation. Therefore, it is very necessary to develop a set of safe, continuous and efficient marine-emerged ceramic desalination equipment.

[0005] In addition, there is also data indicating that in specific fields such as ceramics, the desalination device does not take into account the soluble salts invading into the tiny pores of ceramics under deep-sea high-pressure conditions, which are difficult to be removed by conventional devices, and all known technical solutions for removing them are time-consuming and laborious. Summary of the Invention

[0006] Problems to be Solved by the Invention: In view of the above problems, the purpose of the present invention is to provide a desalination device for marine unearthed ceramics, which can quickly achieve batch, rapid, efficient and safe desalination of marine unearthed ceramics.

[0007] Technical Means for Solving the Problems: The present invention provides a desalination device for marine unearthed ceramics, comprising: a deionized water generating device for generating deionized water; a pneumatic system connected to the deionized water generating device; a desalination module assembly connected to the pneumatic system and having a reverse osmosis module and a sample placement cavity; and a waste liquid recovery device connected to the sample placement cavity of the desalination module assembly; the sample placement cavity has an inlet connected to the pneumatic system and an outlet connected to the waste liquid recovery device; the deionized water generating device, the pneumatic system, the sample placement cavity and the waste liquid recovery device form a recovery water flow path in this order; the reverse osmosis module is connected to the pneumatic system and has a reverse osmosis component in direct contact with the solution in the sample placement cavity; the pneumatic system, the sample placement cavity and the reverse osmosis component of the reverse osmosis module form a circulating water circuit in this order.

[0008] Effects of the Invention: The present invention can provide a desalination device for marine unearthed ceramics, which can address the shortcomings of low desalination efficiency, poor effect and high energy consumption in the existing desalination technologies and equipment for marine unearthed ceramics. Based on the clarification of the performance evolution characteristics and disease formation mechanisms of ceramic cultural relics under the coupling action of multiple factors in the marine environment, through the coupling action of multiple fields, it can achieve efficient, safe and green desalination of different types of pottery in different sea areas, effectively improve the desalination effect and economic environmental protection, and has strong popularization potential. Specifically, first, according to the sea area environment, depth and type of unearthed ceramics, the working ranges of device pressure, temperature and the type of reverse osmosis membrane are determined; secondly, based on the coupling action of multiple fields such as pressure, temperature, ultrasound and pure water circulation, efficient, safe and green desalination of ceramics is achieved; finally, based on the conductivity monitoring module of the device, the degree of desalination completion is determined, and the collection of salt crystals is realized at the waste water recovery device. Thus, by setting the pressure in the device to be less than or equal to the pressure of the unearthed ceramics in the marine environment, the soluble salts can be more easily dissolved in the micro pores to complete effective desalination, and at the same time, the damage to cultural relics caused by excessive pressure is avoided. In addition, the present invention is not limited to the effective desalination of marine unearthed ceramics, but can also achieve the desalination of unearthed cultural relics from archaeological excavations, and has strong popularization potential. Under the positive and negative pressure circulation action in the ultrasonic module and the assembly, the salt content of the internal circulating water is always lower than that of the ceramic sample, and the concentration difference drives the ceramics to be more easily desalinated. The temperature module increases the solubility of the soluble salts in the circulating water, making the ceramics more easily desalinated. Description of the Drawings

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

[0012] The present invention also provides a marine water-emerged ceramic desalination device D (hereinafter also simply referred to as desalination device D or device D). Aiming at the shortcoming of low desalination efficiency, poor effect and high energy consumption in the existing marine water-emerged ceramic desalination technology and equipment, based on the clear understanding of the performance evolution characteristics and disease formation mechanism of ceramic cultural relics under the coupling action of multiple factors in the marine environment, it can quickly realize the batch, rapid, efficient and safe desalination of marine water-emerged ceramics. It can efficiently, safely and greenly desalinate different sea areas and different types of pottery, and has strong popularization. Through the multi-field coupling action of pressure, temperature, ultrasound and pure water circulation, the desalination effect and economic environmental protection are effectively improved.

[0013] As Figure 1 shown, the desalination device D according to the present invention includes: a deionized water generating device 1, a pneumatic system 2, a desalination module assembly, a conductivity monitoring module 7 and a waste liquid recovery device 8. Among them, the deionized water generating device 1 is connected to the pneumatic system 2 through a pipeline, the pneumatic system 2 is respectively connected to the desalination module assembly through two pipelines, the desalination module assembly is composed of a temperature control module 3, an ultrasonic module 4, a reverse osmosis module 5, a sample placement cavity 6 and a conductivity monitoring module 7, and the waste liquid recovery device 8 is connected to the desalination module assembly through a pipeline. According to the above structure, by completing the multi-field coupling action of pressure, temperature, ultrasound and pure water circulation, the desalination effect and economic environmental protection are effectively improved.

[0014] <Deionized water generating device 1> In this embodiment, the deionized water generating device 1 is used to generate deionized water, and the generated deionized water can dissolve the soluble salts attached to the ceramic surface. Moreover, the deionized water generating device 1 is directly connected to the pneumatic system 2, and the deionized water (pure water) is transported to the inside of the desalination module assembly under high pressure. Due to the ion concentration difference, the soluble salt ions 10 immersed in the ceramic diffuse into the deionized water and are thus carried away. Then, the deionized water carrying the soluble salt ions 10 circulates continuously through the reverse osmosis module 5. Specifically, under the synergistic action of pressure and the reverse osmosis membrane, the pure water in the deionized water carrying the soluble salt ions 10 enters the reverse osmosis module 5, and the "soluble salt ions 10" and their solution blocked outside the reverse osmosis membrane enter the recovery module 8 as waste water. By means of this, while increasing the purification effect, it is also beneficial to the overall water conservation of the device D.

[0015] <Pneumatic system 2> In this embodiment, the air compression system 2 is connected to the deionized water generating device 1 through a pipeline 12, and is used to convey deionized water to the desalination module assembly. In addition, the air compression system 2 is also respectively connected to one end of the desalination module assembly (i.e., one end of the sample placement cavity 6 described later) through a bifurcated pipeline 11, and the air compression system 2 is also respectively connected to the other end of the desalination module assembly (i.e., one end of the reverse osmosis module 5) through a bifurcated pipeline 22, and is used to increase the water pressure and evacuate the air in the sample placement cavity 6 inside the desalination module assembly. By means of this, through the positive and negative pressure cycle inside the desalination module assembly, the circulation of the solution in the pores of the ceramic to be desalinated is increased, and the removal of the soluble salts in the ceramic is accelerated.

[0016] Moreover, in this embodiment, the air compression system 2 and the deionized water generating device 1 can determine the vacuum degree, pressure, ion concentration difference, etc. inside the device D (i.e., inside the desalination module assembly, that is, inside the sample placement cavity 6) according to the type and depth range of the sea area where the ceramic is located, so that the ceramic is more likely to be desalinated due to the driving action of the concentration difference and pressure, etc.

[0017] <Desalination module assembly> Hereinafter, the desalination module assembly will be described in detail. In this embodiment, the desalination module assembly includes: a temperature control module 3, an ultrasonic module 4, a reverse osmosis module 5, a sample placement cavity 6, and a conductivity monitoring module 7.

[0018] Specifically, as Figure 1 、 2 shown, in this embodiment, the reverse osmosis module 5 is formed in a hollow cylindrical shape filled with liquid inside, and is respectively connected to the air compression system 2 through a bifurcated pipeline 22 at one end in the length direction to form a circulating water circuit. In the reverse osmosis module 5, a cylindrical reverse osmosis membrane 9 is provided as the core reverse osmosis component. The reverse osmosis membrane 9 is in direct contact with the sample placement cavity 6, and its working mechanism is mainly to filter the soluble salt ions 10 in the ceramic. Specifically, it allows water molecules to pass through (as shown by the arrow), but can block all dissolved salts and organic substances with a molecular weight greater than 100. That is, the reverse osmosis module 5 is a structure for filtering a solution with soluble salt ions composed of the reverse osmosis membrane 9.

[0019] Furthermore, in this embodiment, the salt rejection rate of the reverse osmosis membrane 9 should be at least greater than 98%. For example, nano-ceramic membranes, polyphenylsulfone terephthalamide membranes, polybenzimidazole membranes, sulfonated polyphenylene ether membranes, sulfonated polysulfone membranes, polytetrafluoroethylene graft membranes, inorganic porous glass membranes, and graphite oxide membranes, etc. can be selected, but not limited to the above. As long as it can achieve membrane separation operation that uses the pressure difference as the driving force to separate the solvent from the solution. Also, in this embodiment, when using a reverse osmosis component with a nano-ceramic membrane as the reverse osmosis medium, a high concentration gradient of the salt content between the inside of the ceramic and the external solution can be formed, so as to apply pressure to the soluble salt ion solution on one side of the membrane and exceed its osmotic pressure. At this time, pure water as the solvent will perform reverse osmosis against the direction of natural osmosis, thereby improving the water treatment quality and desalination efficiency.

[0020] Furthermore, as Figure 1 shown, in this embodiment, the sample placement cavity 6 is formed in a long strip shape in the form of surrounding the reverse osmosis module 5, that is, the two are formed into a nested structure similar to a "hui" character shape, etc. The water inlets at one end in the long side direction of the sample placement cavity 6 are respectively connected to the air pressure system 2 through pipelines 11, and the water outlets at the other end in the long side direction are respectively connected to the waste liquid recovery device 8 through pipelines 33. When working, it is filled with deionized water inside, and after desalination treatment, it becomes a solution containing soluble salt ions 10. Also, in this embodiment, the sample placement cavity 6 is made of stainless steel and is not easily corroded in a high-salt solution environment. Its size can be selected according to the shape and quantity of the ceramics to be processed as needed. Also, the sample placement cavity 6 has a base (not shown) made of a stainless steel network frame for fixing the ceramics to be desalted, so that desalination can be carried out under the action of the internal circulating water. Also, the base is formed into a structure that can be disassembled from the sample placement cavity 6, and its size, shape, and quantity can be set and replaced according to the size of the device D, the internal structure, and the shape and quantity of the ceramics to be desalted, so as to improve portability and adaptability.

[0021] In addition, the shapes and positional relationships of the reverse osmosis module 5 and the sample placement cavity 6 are not limited to the above, and can also be formed into other forms, as long as it can ensure that the sample placement cavity 6 is in full contact with the reverse osmosis module 5. For example, the pipelines 11 and 33 do not have to be two, and can also be one each, so as to further simplify the structure. For another example, it can also be that the sample placement cavity 6 is formed into a hollow shape and there are multiple ones formed in the form of surrounding the reverse osmosis module 5 respectively. At this time, the pipelines 11 and 33 should be the corresponding quantities. Based on this structure, independent control of multiple sample placement cavities 6 can be achieved, and at the same time, desalination treatment of ceramics with different requirements can be realized. For another example, it can also be formed into a grid structure in which the sample placement cavity 6 and the reverse osmosis module 5 are alternately adjacent. At this time, the contact area is large and the circulating desalination effect is good.

[0022] Furthermore, in the present embodiment, the temperature control module 3 is located on one side of the sample placement cavity 6 and is used to control the temperature of the solution in the sample placement cavity 6. Since ceramics are more likely to desalt under heating conditions, the temperature control module 3 can determine the internal environmental temperature according to the maximum temperature value of the solubility of soluble salt ions. For example, the temperature is preferably controlled between 25 and 60 °C, which is beneficial to increasing the removal of soluble salts in the ceramics. However, the temperature control is not limited to this and can be specifically set according to specific circumstances. In addition, the installation position and specific form of the temperature control module 3 are not limited to the above, as long as the temperature control of the internal liquid can be achieved to promote desalination without causing structural interference.

[0023] Furthermore, in the present embodiment, the ultrasonic module 4 is located on the other side of the sample placement cavity 6 and is used to perform ultrasonic vibration on the solution in the sample placement cavity 6. Since soluble salt ions are more likely to dissolve under the action of ultrasonic waves, the ultrasonic module 4 can determine the ultrasonic frequency according to the storage state and vulnerability of the ceramic sample. For example, the ultrasonic frequency is preferably controlled between 100 Hz and 200 kHz, which is beneficial to enhancing the diffusion of ions in water and thus increasing the removal of soluble salts in the ceramics. However, it is not limited to this and can be specifically set according to specific circumstances. In addition, the installation position and specific form of the ultrasonic module 4 are not limited to the above, as long as the ultrasonic vibration of the internal liquid can be achieved to promote desalination without causing structural interference.

[0024] In addition, in the present embodiment, the temperature control module 3 and the ultrasonic module 4 are respectively located on both sides of the sample placement cavity 6 in a facing manner, but it is not limited to this. As long as their respective functions can be achieved, the installation positions can be adjusted according to the situation.

[0025] Furthermore, in the present embodiment, the conductivity monitoring module 7 is installed in the sample placement cavity 6 and can be used to monitor the degree of ceramic desalination in real time. When its value decreases and stabilizes, the desalination work is completed. Thus, it can effectively indicate the working efficiency of the device D, perform real-time regulation, and save electricity. In the present embodiment, the conductivity monitoring module 7 is set to one, but it is not limited to this. It can be respectively arranged at different positions in the sample placement cavity 6 according to specific requirements, or it can be omitted.

[0026] <Waste liquid recovery device 8> In the present embodiment, the waste liquid recovery device 8 is respectively connected to the water outlet of the sample placement cavity 6 through a pipeline 33, and is used for collecting desalinated wastewater and can recover and utilize salt crystals through evaporation and other means. In other words, the deionized water generated by the deionized water generating device 1 becomes wastewater after passing through the air compression system 2 and the desalination module assembly, and is recovered by the waste liquid recovery device 8, forming a recovery water flow path.

[0027] In addition, in the present embodiment, valves are provided on the above pipelines 12, 11, 22, and 33, and these valves can be specifically set according to specific requirements, such as one-way valves or check valves, etc.

[0028] <Operating mode of desalination device D> According to the above structure, the deionized water (pure water) generated by the deionized water generating device 1 enters the air compressor system 2 through the pipeline 12, and enters the sample placement cavity 6 through the water inlet through the pipeline 22 respectively. After the deionized water enters the sample placement cavity 6, it directly contacts the ceramics inside and undergoes desalination treatment. The formed waste liquid enters the waste liquid recovery device 8 (i.e., the recovery water flow path) through the pipeline 33 via the water outlet respectively. On the other hand, the pure water that enters the reverse osmosis module 5 through the reverse osmosis membrane enters the air compressor system 2 through the pipeline 22, and then enters the next cycle for reuse, continuing to dissolve the soluble salts in the ceramics (i.e., the circulating water circuit).

[0029] Thus, the desalination device D according to the present invention effectively improves the desalination effect through the multi-field coupling effects of high and low pressure cycling, heating control, ultrasonic dissolution promotion, reverse osmosis, etc.; saves water resources through the repeated use of water, monitors the progress of the treatment in real time through the conductivity monitoring device 7, and recovers and utilizes salt crystals through the waste water recovery device 8, effectively improving the economic and environmental protection performance, and can perform efficient, safe and green desalination on different sea areas and different types of pottery, with wide adaptability and strong popularization.

When the desalination was completed, the conductivity was less than 0.49 us / cm, and the desalination rate of the reverse osmosis composite membrane was greater than 97%. The internal water of the reverse osmosis membrane 9 was recycled.

[0034] <Example 4> Desalination tests were carried out on the ceramics taken out of the South China Sea. The pressure of the air compressor system 2 was set at 1.5 - 2.0×10 7 Pa according to Example 1. The temperature was set at 60°C according to Example 1, and the frequency of the ultrasonic module 4 was set at 1000 - 5000 Hz.
