Description

Technical Field

[0001] The utility model belongs to the technical field of high-salt wastewater evaporation equipment, in particular to a high-salt wastewater evaporation crystallization device. Background Art

[0002] High-salinity wastewater evaporation is a method for treating high-salinity wastewater. The main purpose is to remove water from the wastewater through evaporation, concentrate the salt and possibly further treat or utilize it as a resource. High-salinity wastewater usually comes from industrial production processes such as chemical, pharmaceutical, printing and dyeing, and oil refining. It contains high concentrations of salt, such as Cl-, SO42-, Na+, Ca2+ and other salt substances. If these wastewaters are discharged directly, they will have a serious impact on the environment. Therefore, they need to be effectively treated. There are many forms of evaporation technology, such as multi-effect evaporation and mechanical vapor recompression evaporation. Among them, multi-effect evaporation is to pass the hot steam through several evaporators in series in sequence to achieve step-by-step utilization of the heat source, thereby improving the evaporation efficiency. Mechanical vapor recompression technology (MVR technology) uses a steam compressor to effectively utilize the heat source and improve the thermal utilization efficiency of steam. During the evaporation process, the wastewater is heated to boiling, the water evaporates into steam, and the salt remains in the concentrate. The condensed water after evaporation can meet the emission standards through subsequent treatment, and the concentrate can be further treated by crystallization, drying or incineration.

[0003] When high-salt wastewater is evaporated, a crystallization device is needed. The patent publication number is CN212894307U.

Beneficial effect: By starting the fan, the hot steam inside the evaporation box can be extracted outward through the connecting pipe and the exhaust pipe, accelerating the exhaust speed, and injecting water into the inner bottom end of the shell. The exhaust pipe can exchange heat with the water when passing through the shell, thereby transferring the temperature of the hot steam to the water, and the hot air enters the top of the support plate through the vent hole, which can ensure the interior of the shell, forming the effect of waste heat utilization.
