Cascaded concentrated seawater drainage diffusion device

Abstract

The invention discloses a cascade-type concentrated seawater discharge diffusion device, which comprises a discharge straight pipe and a diffusion branch pipe connected to the side of the discharge straight pipe, wherein: the end of the diffusion branch pipe is connected with water that can discharge the water outside the end of the diffusion branch pipe. A cascade mixing tube that sucks in and mixes and then discharges again. By adding cascading mixing tubes as needed, the bottom seawater, which is neglected by the prior art, can be involved in the dilution and mixing, and the dilution and mixing can be decomposed into two steps, that is, the first step is the seawater inhaled from the outside of the diffusion branch pipe and the water in the diffusion branch pipe. Thick seawater is mixed for the first time, and then sprayed out at the end of the diffuser is mixed with natural seawater again to dilute. In this way, the design emission can be increased and the production increase cost can be reduced. Since the cascade mixing tube can be disassembled, it has an emergency function. The invention has the advantages of being able to dilute by seawater at the bottom, having low resistance loss, good dilution effect, small equipment loss, good engineering reserve, preventing landslides, and strong expansion emergency capability.

Description

technical field [0001] The invention relates to a sea discharge diffusion device, in particular to a cascaded concentrated seawater discharge diffusion device. 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%.

AI Technical Summary

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
