Spraying evaporation concentration salt separation device and salt separation method

Abstract

The invention discloses a spraying evaporation concentration salt separation device and a salt separation method. The device comprises a spraying evaporation concentration salt separation device towerbody and a ground source heat pump system communicated with the spraying evaporation concentration salt separation device tower body, wherein the upper part of the spraying evaporation concentrationsalt separation device tower body is provided with a spraying system communicated with the ground source heat pump system; a filing material layer is arranged at the middle part; heat exchange air guide equipment is arranged under the filling material layer; a concentration brine collecting pool is arranged under the spraying evaporation concentration salt separation device tower body; blast blowing equipment is connected onto the heat exchange type air guide equipment; a ground source heat pump host arranged in the ground source heat pump system is communicated with an original brine box; anoriginal brine box heat exchange assembly, the ground source heat pump host and the heat exchange type air guide equipment form a closed loop through a pipeline; through the heat exchange assembly ofthe ground source heat pump system, the original brine cools; partial salt is separated out to generate solid; brine is conveyed to the spraying system by the original brine box; under the effect of the heat exchange type air guide equipment, the evaporation concentration is performed to reach the brine concentration salt separation. The device and the method have the advantages that the evaporation efficiency is high; the time is short; the energy consumption is low; the equipment is simple; the combination is easy.

Description

Technical field [0001] The invention belongs to the field of evaporation and concentration, and specifically relates to a spray evaporation, concentration and salt separation device and a salt separation method. Background technique [0002] At present, there are two main methods used for the evaporation and concentration of brine: 1. Using natural evaporation to pass the brine through the salt field to dry the salt, and using solar energy to evaporate and concentrate the brine. This method uses solar natural evaporation process, low energy consumption, but has the disadvantages of large salt field area, low evaporation efficiency, long cycle, and limited by the natural conditions of the salt field; 2. The forced evaporation process is used to force brine through the evaporator. The method has high evaporation efficiency and small floor space, but at the same time has the disadvantages of high equipment cost and high energy consumption. Based on this, it is necessary to develop ...
