Problems solved by technology
Although the structure of the device is simple and easy to install, its control over the density of pebbles and the energy consumption of sea discharge still need to be improved
At the same time, the known technology has insufficient consideration for the degree of project reservation, and it is difficult to meet the sea discharge requirements of later project development
It is usually compensated by replacing old equipment with new equipment, which significantly increases the operating cost of the device and the cost of equipment renewal

Embodiment
[0012] Example: refer to figure 1 , a device for diverting concentrated seawater into the sea, comprising a discharge straight pipe 1 and a diffusion branch pipe 3 connected to the side of the discharge straight pipe, wherein: the diffusion branch pipe 3 near the base of the discharge straight pipe 1 is provided with a duckbill Valve 2; the diffusion branch pipe 3 near the end of the discharge straight pipe 1 is open, and does not have a duckbill valve 2; the diameter of the diffusion branch pipe 3 increases sequentially from the base of the discharge straight pipe 1 to the end of the discharge straight pipe 1; The end of the dry pipe 1 is closed by a head, and the head is connected with a buoyancy matching extension device. The successively larger diameters of the diffusion branch pipe 3 and the structure of no duckbill valve 2 on the lower side of the upper duckbill valve 2 can make the discharge flow of the whole row of branch pipes more balanced, and prevent the local conc...

The invention discloses a novel concentrated seawater discharging dispersion device, which comprises a releasing straight trunk pipe and dispersion branch pipes connected on the side face of the releasing straight trunk pipe. Dispersion branch pipes which are close to the base part of the releasing straight trunk pipe are provided with duckbill valves; dispersion branch pipes which are close to the tail end of the releasing straight trunk pipe are provided with openings but not provided with duckbill valves; pipe diameters of the dispersion branch pipes are sequentially increased from the base part of the releasing straight trunk pipe to the tail end of the releasing straight trunk pipe; the tail end of the releasing straight trunk pipe is sealed by a seal head, and the seal head is connected with a buoyancy matching extending device. Due to the sequential increasing of the pipe diameters of the dispersion branch pipes and the structure with duckbill valves at the upper side and the lower side having no duckbill valves, the whole branch pipe column has a balanced discharging amount. Therefore, the novel concentrated seawater discharging dispersion device has the advantages that the dispersion requirement is met, the quality of the nearby sea area environment is not influenced, resistance loss is low, equipment loss is small, an engineering reservation degree is good, landslide is prevented, and an emergency ability is quick.
Description
technical field [0001] The invention relates to a sea-discharge diffusion device, in particular to a sea-discharge diffusion device for concentrated seawater. Background technique [0002] At present, my country has built 1,000-ton and 10,000-ton demonstration projects with independent intellectual property rights. Many 10,000-ton and 100,000-ton seawater utilization projects in Tianjin, Zhejiang, Hebei, Qingdao, and Dalian have been put into operation one after another. However, my country's seawater desalination industry is currently in the initial stage of vigorous development, accounting for a small proportion of my country's freshwater consumption, but the development is strong and the prospect is good. It is estimated that by 2015, my country's seawater desalination capacity will reach 2.2 million to 2.6 million cubic meters per day in general, and the contribution rate to the newly added fresh water supply in coastal water-scarce areas will reach more than 15%.
