A containing cavity is formed in a shell; a sampling spoon groove and a gas storage cavity are formed in the sampling body, the sampling body is connected with the shell and seals the containing cavity, and the sampling spoon groove is formed in the containing cavity; the air bag is arranged in the air storage cavity and is pre-filled with anaerobic gas; the operation part is matched with the sampling body and seals the air storage cavity, and the operation part moves relative to the sampling body and acts on the air bag to damage the air bag; the one-way ventilation structure is configured to allow anaerobic gas released by the air bag to flow into the accommodating cavity in a one-way manner and allow the gas to be discharged from the accommodating cavity to the atmosphere in a one-way manner. External anaerobic equipment is not needed, through the pre-inflation bag and the one-way ventilation structure, air replacement of the containing cavity can be completed on site after sampling, and the problem of oxygen exposure in the anaerobic bacteria transfer process is fundamentally solved.

The utility model discloses a small-sized associated gas wet desulphurization device which comprises an absorption tower, a liquid separation bag and a precipitator, an associated gas inlet is arranged at the lateral lower part of the absorption tower, a solution inlet is arranged at the lateral upper part of the absorption tower, a purified gas outlet is arranged at the top of the absorption tower, and the purified gas outlet is connected to a gas inlet of the liquid separation bag; a liquid phase outlet is formed in the bottom of the absorption tower and connected to a liquid inlet of the precipitator, a gas outlet in the top of the liquid separation bag is connected to a downstream natural gas pipeline, a liquid outlet in the bottom of the liquid separation bag is connected to the liquid inlet of the precipitator, a filtering system is arranged outside the precipitator, and an oxygen exposure device is arranged inside the precipitator. A barren liquor outlet of the precipitator is connected to a solution inlet of the absorption tower. On the premise of thoroughly changing the production mode of the original dry-type desulfurization tower, the operation risk of safe operation is reduced, the corrosion to a gathering and transportation pipe network is reduced, the production and operation cost is effectively reduced, and the safe and environment-friendly operation of oil and gas field production is ensured.

The present application relates to a kind of wetland remediation protection equipment, including two installation plates, movable connection is carried with the bearing plate between installation plate along vertical direction;Support frame is hinged to the front end of bearing plate, and support frame is rotatably provided with turnover roller;Bearing plate top is equipped with liquid medicine tank, and bearing plate bottom is fixedly provided with spraying assembly and multiple rotatably connected aeration cylinder, and aeration cylinder is equipped with aeration hole arranged along helical line track interval, and the side wall of aeration cylinder is equipped with stirring blade, and the edge of the rotating radial outside of stirring blade is equipped with cutting edge, and stirring blade is alternately staggered arrangement in the axial direction of aeration cylinder;The side of installation plate top is equipped with gas supply assembly for each aeration cylinder to transport gas.The present application is through to bottom sludge turnover, spray, oxygen exposure and the synergistic effect of stirring, can break bottom sludge hardening layer release adsorbed state pollutant, promote reagent and pollutant fully mixed, also simultaneously improve dissolved oxygen content, so that aerobic microorganism can also participate in pollutant degradation, improve overall repair speed.

The utility model discloses a novel square fishpond oxygen aeration device which comprises a square fishpond, a lifting assembly is arranged on one side of the square fishpond, one end of the lifting assembly is fixedly connected with a mounting plate, and a first movable rod is slidably mounted in the mounting plate in the vertical direction. Through the arrangement of the first movable rod, the diving aerator, the telescopic assembly and other parts, when the device is not used, the electric hydraulic push rod end drives the fixed ring at the top of the first movable rod to move downwards, and meanwhile, the first movable rod drives the diving aerator to move downwards, so that the distance between the diving aerator and the movable ring is lengthened; the telescopic spring pushes the movable ring to be attached to the bottom of the mounting plate, at the moment, the second movable rod deflects and pulls one end of the corresponding sleeve to move towards the surface of the submersible aerator, after the sleeve moves in place, the connecting hole in the surface of the sleeve and the aeration hole in the surface of the aeration pipe are completely staggered, and air backflow is effectively prevented.

A method and apparatus for a two-piece capsule configured to expel air and reduce bubbles within a composition. The invention features a capsule with a cap and body, where the cap includes an insert with a dome shape designed to compress against the meniscus of a fluid composition or powder. This compression minimizes trapped air and enhances the capsule's structural integrity and longevity. Additionally, the capsule may employ a sealing element to prevent leakage, ensuring a stable, bubble-free environment for the contents. The capsule's design allows for efficient filling and reduces oxygen exposure, thus preserving the quality of the encapsulated material. The invention can be used for both powder and liquid encapsulations, enhancing shelf life and stability by significantly reducing internal air and maximizing fill volume.
