Carbon-saving desalted water post-treatment mineralization system

Abstract

The invention discloses a carbon-saving desalted water after-treatment mineralization system which comprises a desalted water tank, a water outlet of the desalted water tank is sequentially connectedwith a first water supply pump, a water ejector and a carbon dioxide absorber through pipelines and then connected with a first liquid inlet of a mixer, the other water outlet of the desalted water tank is sequentially connected with a second water supply pump and a second liquid inlet of the mixer through pipelines, a liquid outlet of the mixer is connected with the bottom of a limestone contactor through a pipeline, the top of the limestone contactor is connected with a liquid distributor in the top of a decarburization device through a pipeline, a filler is arranged in the decarburization device, the bottom of the decarburization device is connected with a water delivery pump through a pipeline and then leads to a water receiving point, and the top of the decarburization device is connected with a water ejector air inlet of the water ejector through a pipeline. According to the carbon-saving desalted water after-treatment mineralization system, by introducing the decarburization device and the water ejector, residual carbon dioxide in desalted water after-treatment is recycled, and the carbon dioxide consumption of the mineralization system is remarkably reduced.

Description

technical field [0001] The invention belongs to the field of post-treatment of desalinated water, in particular to a carbon-saving desalinated water post-treatment mineralization system. Background technique [0002] As an open-source incremental technology to realize sustainable utilization of water resources, desalination of salt water has become an important means to solve the water crisis in coastal and inland areas around the world. At present, the salt water desalination industry at home and abroad is developing rapidly. According to the data released by the British GWI company, by the end of 2016, the global installed capacity of salt water desalination reached 95.59 million tons per day, and the actual operation was 88.56 million tons per day. More than 100 users in all continents countries. According to the data released by the former State Oceanic Administration, by the end of 2016, 131 seawater desalination projects had been built nationwide, with a project scale...
