This invention discloses a cultivation experimental device for studying plant ectomycorrhizal fungal interactions. It includes a base with a petri dish on it. A protective shell is installed around the petri dish on the top of the base. A circular plate is rotatably mounted inside the protective shell. Both the circular plate and the top surface of the protective shell have two symmetrical arc-shaped ventilation openings. An adjustment component connects the circular plate and the protective shell, including a splined sleeve rotatably connected to the top of the protective shell. This invention provides a cultivation experimental device for studying plant ectomycorrhizal fungal interactions that offers high adjustment precision, effortless operation, and stability. The precise design of the ventilation opening adjustment component allows for accurate control of the opening size, meeting the oxygen requirements of different fungal species and plants. Furthermore, the threaded connection of the protective shell enhances the stability and practicality of the device, providing strong support for scientific research.

This invention relates to the field of waste incineration system technology, specifically to an energy-saving oxygen-enriched incineration system for municipal solid waste in high-altitude areas. The system includes an incinerator, a secondary combustion section, and an exhaust pipe connected in sequence. The incinerator contains a primary combustion chamber with a first combustion grate. An air supply section is located on the side of the incinerator, containing a mixing chamber. The air supply section is equipped with oxygen supply equipment and a blower connected to the mixing chamber. A horizontal air pipe connected to the mixing chamber is horizontally arranged within the primary combustion chamber. Several vertical air pipes are vertically arranged above the horizontal air pipes, with their upper ends positioned above the first combustion grate. Several short exhaust pipes are arranged on the outer wall of the vertical air pipes, with the exhaust pipes angled downwards from one end connected to the vertical air pipe to the other. This invention addresses the problem in existing technologies where increased energy consumption during the incineration of municipal solid waste in high-altitude areas is easily caused by factors such as oxygen content and temperature.

This invention discloses an internal and external dual-circulation airlift aerobic fermentation device, relating to the field of microbial aerobic fermentation. The device includes a gas conveying system, a fermenter, a circulating pump, a circulating cooler, a liquid distributor, a liquid-gas jet emulsification device, a gas distributor, a guide tube, an internal coil heat exchanger, and a circulating liquid suction device. This invention utilizes multiple centrally symmetrical liquid-gas jet emulsification devices within the fermenter, employing high-speed liquid flow to strongly shear and collide with the gas phase, breaking the air into micron-sized fine bubbles, thus significantly increasing the gas-liquid contact surface area. Simultaneously, the use of rotating jets and a guide tube design ensures thorough mixing of the gas and liquid phases during the jetting process, forming an innovative internal and external dual-circulation mode. This invention combines the advantages of traditional mechanical stirring and airlift fermenters, significantly improving the production capacity and oxygen utilization rate of the fermentation device while substantially reducing energy consumption.

This invention belongs to the field of contact lens technology, and provides a moisturizing protein-based contact lens and its preparation method. The preparation method includes the following steps: mixing a silk fibroin solution and a hyaluronic acid-binding protein solution to obtain a protein mixture solution; mixing a hydrophilic modification component, an oxygen-permeable modification component, and water to obtain a composite modifier; mixing the protein mixture solution, the composite modifier, and a crosslinking agent to obtain a pre-crosslinked mixture; molding the pre-crosslinked mixture and performing gradient crosslinking, followed by sequential soaking in buffer solution, rinsing, and sterilization to obtain the moisturizing protein-based contact lens. The contact lens of this invention uses protein as the main component, does not rely on silicon-based substances or harmful crosslinking agents, and possesses high biocompatibility, high oxygen permeability, suitable mechanical properties, and controllable degradation.

This utility model discloses a reservoir-type closed-loop water body in-situ water purification device, comprising an upper floating island and a lower floating island arranged vertically. The upper floating island includes a water tank with an open top, made of a material with a density less than that of water, and has a leakage hole at the bottom. The lower floating island includes a support frame, with a support rod fixed to the top of the support frame for connecting to the water tank. A floating body for planting aquatic plants is installed at the top of the support frame. Multiple sets of suspended biological packing materials are evenly suspended within the space enclosed by the support frame. A submersible pump is located at the geometric center of the area with the suspended biological packing materials. A nozzle is installed at the top of the water tank, and the submersible pump is connected to the nozzle via a water pipe passing through the water tank. Micro-aeration devices are evenly distributed within the support frame. Aquatic plants are planted on both the water tank and the floating body. The device has a simple structure, is easy to assemble, and provides good purification effect.
