Eco-friendly cascading concentrated seawater discharge method

Abstract

The invention discloses an eco-friendly cascading-type concentrated seawater discharging method, which comprises steps of presetting, putting into production and capacity expansion. If the concentrated seawater discharging amount is further expanded according to requirements of a post project, a flange seal head at the tail end of a releasing straight trunk pipe is opened, a slightly large pipe diameter construction space is preserved, corresponding expansion is executed conveniently, a buoyancy force is provided, and an original newly-cut pine block can be removed conveniently. As a certain buoyancy force is provided while expansion is facilitated, a corresponding matched buoyancy force can be provided for the overall device. Advantages of good preservation and quick construction are provided, and emergency treatment demands can be met. In order to facilitate expansion of the releasing straight trunk pipe, a column-shaped object whose diameter is slightly larger than that of the releasing straight trunk pipe is additionally arranged at the tail end of the releasing straight trunk pipe. The eco-friendly cascading-type concentrated seawater discharging method has the advantages that bottom seawater can be used for diluting; resistance loss is low; diluting effects are good; an engineering preservation degree is good; landslide is prevented; and a capacity expansion emergency ability is strong.

Description

technical field [0001] The invention relates to an ecological concentrated seawater discharge diffusion production and production increase method, in particular to an ecologically friendly cascade concentrated seawater discharge method. 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 fr...

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
