The application discloses a method for regulating bubble size in a high-temperature molten salt bubbling tower, comprising the following steps: according to the diameter range of the target bubble required by the bubbling tower, a single-hole bubbling experimental device is built by selecting a bubble distributor with a corresponding characteristic aperture; according to the component of the molten salt required by the bubbling tower, a database of the relationship between the molar ratio of each chemical component of the molten salt and the physical properties is established; in the single-hole bubbling experimental device, a regulation mode is selected according to the size of the characteristic aperture of the bubble distributor, the adjustable range of the bubble diameter is adjusted to the diameter range of the target bubble required by the bubbling tower; and the obtained regulation mode is applied to the bubbling tower; the application can reveal a comprehensive solution of the synergistic mechanism among multiple parameters, so as to realize accurate and predictable control of the bubble size from microns to millimeters, and solve the technical problems from laboratory research to industrial device amplification.

The utility model belongs to the technical field of air bubble films, particularly relates to an air bubble film with a multi-buffering structure, and aims to solve the problems that the conventional air bubble film is insufficient in buffering and protecting effect and often needs to be wound on the surface of an object to improve the protecting effect, but too much space is undoubtedly occupied due to excessive overlapping and winding, so that the transportation efficiency and the transportation cost are influenced. According to the technical scheme, the buffer structure comprises a first air bubble film, a plurality of small air bubble columns are evenly arranged on the surface of the first air bubble film, and a nested buffer piece is arranged on the first air bubble film and used for improving the buffer performance of the whole structure. When the air bubble film is used, due to the arrangement of the nested buffering piece and the composite buffering piece, the air bubble film has a multi-buffering structure, impact force can be effectively absorbed and dispersed, the buffering performance is remarkably improved, and the structure is particularly suitable for packaging and transporting fragile, precious or sensitive objects such as electronic products and glass products.

The invention relates to a tower-type reaction device and process for gas-liquid reaction of grease, the reaction device comprises a tower-type reactor, an ozone generator and a material delivery pump, the tower-type reactor is sequentially provided with a tube nest reaction area I, a bubbling reaction area II and a tower kettle product stabilizing area III from top to bottom, the tube nest reaction area I comprises a liquid distributor and a tube nest packed bed from top to bottom, and a plurality of tube nests filled with fillers are arranged in the tube nest packed bed; the bubbling reaction area II comprises a plurality of layers of bubbling tower plates; bubbling sand core distributors and coil heat exchangers are arranged on the bubbling tower plates; and the tower kettle product stabilizing region III comprises a tower kettle and a tower kettle heat exchanger.

The utility model relates to the technical field of wet-process phosphoric acid defluorination equipment, in particular to a bubble cap tower for wet-process phosphoric acid defluorination, which comprises a tower body, a plurality of layers of tower plates arranged in the tower body from top to bottom, a plurality of bubble caps mounted on the tower plates, a steam outlet arranged at the top of the tower body, and an acid inlet arranged above the topmost tower plate. An acid outlet is formed in one side of the lower part of the tower body, a downcomer is arranged on each layer of tower plate in a penetrating manner, the upper downcomer and the lower downcomer are respectively arranged on two sides of the upper layer of tower plate and the lower layer of tower plate, a partition plate is arranged above the acid outlet, a liquid seal pipe is arranged on the partition plate, and a steam ring pipe and a steam inlet pipe are arranged above the partition plate. By arranging the downcomer, the arrangement of a tower plate overflow weir is canceled, so that the deposition and scaling of sediments are reduced, and the tower plate is convenient to clean; by arranging the liquid seal pipe, the upper air pressure of the tower body is stabilized, and fluctuation is avoided; phosphoric acid is indirectly heated through the steam ring pipe and directly heated through the steam inlet pipe, vibration of steam entering the pipeline is reduced, and the heat exchange efficiency is improved.

The invention provides a multistage bubbling tower type gas-liquid contactor tritium extraction device and method, which is used for extracting tritium from a helium-cooled lithium-lead proliferation cladding of a superconducting magnetic confinement fusion reactor, and comprises a multistage series mechanism arranged at an outlet of the helium-cooled lithium-lead proliferation cladding and used for extracting tritium dissolved in eutectic lithium-lead alloy through carrier gas, the multi-stage series mechanism is formed by sequentially connecting multiple stages of GLC units in series, the height of each stage of GLC unit is decreased stage by stage, and the stage number of the multi-stage series mechanism is larger than or equal to thirteen. All the stages of GLC units are communicated through connecting pipes arranged at different heights, and all the stages of GLC units are arranged in the direction perpendicular to the horizontal plane, so that the problem that the liquid levels of all the GLC units are not uniform in the operation process is solved, and the overall operation stability and safety of the device are improved.
