Embodiment 1

[0083] A high-efficiency dissolved oxygen system for aquaculture, the system includes: two high-exposure dissolved oxygen water preparation equipment, frequency modulation pump 60, oxygen sensor 1' and PLC.

[0084] The high-exposure dissolved oxygen water preparation equipment includes: an oxygen balance tank 10 , a dissolved oxygen generator 20 , a gaseous dissolved oxygen balance device 30 , a gas-liquid interface generator 40 and a water vapor separator 50 .

[0085] The oxygen balance tank 10 is connected to the dissolved oxygen generator 20, the dissolved oxygen generator 20 is connected to the gaseous dissolved oxygen balance device 30, the gaseous dissolved oxygen balance device 30 is connected to the gas-liquid interface generator 40, and the gas-liquid interface generator 40 is separated from the water vapor The water vapor separator 50 is connected with the dissolved oxygen generator 20 and the oxygen balance tank 10 . The gaseous dissolved oxygen balance device 30 ...

Embodiment 2

[0095] A high-efficiency dissolved oxygen system for aquaculture, the system is basically the same as the system in Embodiment 1, the difference lies in the structure of the water vapor separator 50.

[0096] like Figure 4 As shown, the water vapor separator 50 includes: a separator vessel 51 connected with the gas-liquid interface generator 40 and the dissolved oxygen generator 20 . The separator container 51 is provided with: a water inlet 511 , a water outlet 512 and an exhaust port 513 .

[0097] The water inlet 511 is arranged on the bottom of the separator container 51, and the water outlet 512 is arranged on the side of the separator container 51, and the end of the pipeline provided on the water inlet 511 is higher than the height of the water inlet 511 at the side of the separator container 51. The water inlet 511 communicates with the gas-liquid interface generator 40 through a pipeline. The water outlet 512 communicates with the dissolved oxygen generator 20 thro...

Abstract

The invention discloses an efficient oxygen dissolving system for aquaculture and a dynamic intelligent control method of the system. The system comprises a plurality of high-aeration oxygen dissolving water preparation devices, a frequency modulation pump, an oxygen sensor and a PLC (programmable logic controller). Each high-aeration oxygen dissolving water preparation device comprises an oxygenbalance tank, an oxygen dissolving generator, a gaseous oxygen dissolving balance device, a gas-liquid interface generator and a moisture separator, wherein the oxygen dissolving generator is connected with the oxygen balance tank, the gaseous oxygen dissolving balance device is connected with the oxygen dissolving generator, the gas-liquid interface generator is connected with the gaseous oxygendissolving balance device and the oxygen dissolving generator, and the moisture separator is connected with the gas-liquid interface generator, the oxygen dissolving generator and the oxygen balance tank. The oxygen sensor is arranged in aquaculture water, the frequency modulation pump is connected with the oxygen dissolving generator and used for adjusting the quantity of high-aeration oxygen dissolving water conveyed into the aquaculture water, and the PLC is electrically connected with the gaseous oxygen dissolving balance device, the gas-liquid interface generator, the frequency modulationpump and the oxygen sensor. According to the system and the method, automatic control is realized, manpower is effectively saved, and fishpond daily management and cost are effectively reduced.

Description

technical field [0001] The invention relates to an aquaculture dissolved oxygen control system, in particular to an efficient aquaculture dissolved oxygen system and a dynamic intelligent control method thereof. Background technique [0002] With the rapid development of modern technology and aquaculture, the scale of factory farming in various countries has been expanding in recent years, and the new farming technology has achieved remarkable results in increasing fish production, reducing energy consumption, and saving water sources. [0003] China is a big country in aquaculture. Aquaculture production accounts for more than 62% of global production, and national aquaculture production accounts for 73% of total fishery production. At present, the aquaculture model is mainly based on extensive farming, and the output of factory farming only accounts for 0.85% of the total aquaculture output. However, the extensive farming model has low efficiency, poor feed conversion rate...
