Underwater oxygenation method and system

Abstract

The invention relates to an oxygenation method and system. The oxygenation method and system are characterized in that the system comprises an air source station, a control device, an aerial fog pipe network, a pipeline and a pool or a water container; the aerial fog pipe network is composed of a plurality of aerial fog dispersers which are hollow cylindrical pipes; each aerial fog disperser comprises a left base, a right base, a cylindrical pipe body, a cavity, an air inlet pipe and an outer covering film, wherein the outer covering film tightly covers the outer layer of the cylindrical pipe body along the outer diameter of the cylindrical pipe body, the outer covering film comprises a fish wire net layer, a non-woven fabric layer, and a micro-nano film layer and a base layer in sequence from the outmost layer to the innermost layer; one or two grooves are formed in the top of the cylindrical pipe body of each aerial fog disperser in the axis direction in parallel; the center of each groove is provided with an air outlet hole communicated with the corresponding cavity; gas entering the cavities from the air inlet pipes is evenly dispersed in the grooves through the air outlet holes and penetrates through the outer covering films to generate micro-nano aerial fog. A split type oxygen generator (pressure being 1.5-7kg / cm<2>) or an air compressor is provided for the multiple aerial fog dispersers, and the micro-nano serial fog can be generated by each serial fog disperser under the pressure of 0.01-0.05MPa.

Description

technical field [0001] The invention relates to an oxygenation system in aquaculture, in particular to an oxygenation method and system. Background technique [0002] Aquatic animals live in water bodies and depend on food and dissolved oxygen for survival. If there is not enough dissolved oxygen in the water body environment, aquatic species are prone to disease and even death. Especially in high-density breeding of fish, shrimp, turtle, and crab, the amount of dissolved oxygen in the water determines the density of organisms contained in the water body. There will be low dissolved oxygen, so oxygenation is particularly important. Using an aerator can effectively supplement the dissolved oxygen in the pond. [0003] Generally, in ponds with waterwheel aerators, the upper water body rarely lacks oxygen, but it is difficult to provide sufficient oxygen at the bottom of the pond. The pool bottom aeration technology uses the pipes laid at the bottom of the pond to directly t...

Problems solved by technology

However, in larger waters, the pressure of the gas needs to be very high to meet the demand, which increases the requirements for the oxygen machine.
