[0023] Both ends of the vessel body 1 are equipped with end caps 103. The vessel body 1 is configured as a two-section structure, including an upper vessel body 101 and a lower vessel body 102. The lower vessel body 102 is 2000mm high, and the upper vessel body 101 is 1000mm high. The connection between the upper vessel body 101 and the lower vessel body 102, as well as the connection between the end caps 103 and the upper and lower vessel bodies 101 and 102, are all secured with fastening bolts 8. A seawater circulation inlet 104 is provided on the side wall of the lower vessel body 102, and a seawater circulation outlet 105 is provided on the side wall of the upper vessel body 101, facilitating connection with other systems for simulation experiments.

[0024] The wave-generating device includes wave-generating blades 2 and a wave-generating motor 3 installed inside the lower vessel body 102. The wave-generating motor 3 is connected to the wave-generating blades 2 via a magnetic system. The wave-generating motor 3 is a servo motor, which is connected to the internal cavity of the vessel body 1 via a magnetic system to ensure overall sealing. The wave-generating motor 3 is connected to the wave-generating blades 2. By controlling the period and swing angle of the servo motor, the deep-sea seabed surge state is simulated.

[0025] The nozzle assembly is symmetrically arranged inside the two end caps 103 of the vessel body 1. The nozzle assembly includes a nozzle connecting pipe 4, an array of nozzles 5, and a nozzle control motor 6. The array of nozzles 5 includes a nozzle disc 501 and nozzles 502. The nozzle disc 501 has nozzle mounting holes 503 arranged in an array. Nozzles 502 are mounted in the nozzle mounting holes. Nozzle interface plugs 504 are provided at the nozzle mounting holes 503 where no nozzles 502 are installed. The nozzle mounting holes 503 can accommodate single nozzles or different nozzle arrays. One end of the nozzle connecting pipe 4 is connected to the nozzle disc 501, and the other end extends outside the end cap 103 of the vessel body 1. The nozzle connecting pipe 4 is designed to be rotatable. The nozzle control motor 6 controls the nozzle connecting pipe 4 to raise, lower, and rotate the array of nozzles 5. By setting up an array-type, variable-angle, variable-height, and replaceable nozzle assembly, the effects of nozzle structure and nozzle array arrangement on dissolution efficiency can be studied.

[0026] Three sets of viewing windows 7 are arranged on the side wall of the vessel body 1, allowing for multi-angle experimental observation. The three sets of viewing windows 7 are arranged in three layers, with each set containing three sapphire windows. Two windows are arranged opposite each other in each layer, and one window is arranged to the side. The viewing windows 7 are high-pressure sapphire windows, capable of withstanding the corresponding design pressure. Multiple sensor interfaces, including those for temperature and pressure, are also provided around the device, and deep-sea CTD equipment can be installed to realize online testing of relevant parameters such as salinity and pH. Combined with the viewing windows 7 and sensors, the changes in CO2 breakup and diffusion inside the vessel body can be monitored in real time.

[0027] The vessel body 1 is made of 22053 duplex steel, which is resistant to weak acid corrosion and has high strength. It is processed in sections and can withstand a high pressure of 20MPa with sufficient safety margin. The vessel body 1 weighs about 5 tons and is equipped with an overhead crane dismantling device, a matching ladder, and an operation auxiliary system.
