Description

Technical Field

[0001] The utility model relates to the technical field of concentrated water recovery, in particular to a demineralized concentrated water recovery device. Background Art

[0002] Demineralized water refers to the finished water obtained by removing suspended solids, colloids, inorganic cations, anions and other impurities in water through various water treatment processes. Demineralized water does not mean that all salts in the water are completely removed. Due to technical reasons and water production cost considerations, demineralized water is allowed to contain trace impurities according to different uses. After using demineralized water, a lot of concentrated water will be produced. How to treat the concentrated water has become a problem that must be solved.

[0003] The patent with publication number CN 217398681 U discloses a concentrated brine preparation system for ultra-high pressure power generation desalted water, which includes a preparation device, a vaporization box and a condenser. The vaporization box is provided with a primary filter box, an output pipe is connected between the output port of the preparation device and the primary filter box, and a precipitation rack is fixed in the vaporization box. The device reduces the discharge of wastewater and the water cost of the power generation system, the evaporation rate and crystallization rate of the concentrated brine are relatively fast, and the heat energy absorbed by the concentrated brine will be recovered through the condenser, thereby realizing green circulation. However, the device has the problem that after the desalted water is introduced into the primary filter box for filtration, the concentrated water is sprayed to the precipitation rack by a nozzle, but as time goes by, more crystals will be attached to the precipitation rack, which will not only affect the subsequent precipitation treatment of the concentrated water, but also if the concentrated water is to be treated continuously, the precipitation treatment operation of the concentrated water needs to be stopped, the precipitation rack is taken out and the crystals on it are cleaned and reinstalled, thereby greatly affecting the treatment efficiency of the concentrated water. Therefore, a desalted water concentrated water recovery device is proposed to solve the problem that the existing concentrated water recovery device is difficult to quickly separate and collect the concentrated water salt.
