Abstract

This invention discloses a low-temperature evaporation and drying device for high-concentration hazardous waste liquid, including a low-temperature evaporation mechanism. The low-temperature evaporation mechanism includes a support plate, and a lifting leg is fixedly connected to the top surface of the support plate. An insulated clamping box is installed on the lifting leg. A stirring mechanism can rotate the stirring evaporator, causing the area contaminated with waste liquid to be separated from the waste liquid. The stirring evaporator increases the evaporation area of ​​the waste liquid, which helps to increase the evaporation rate and reduce energy consumption. The enhanced stirring element further increases the evaporation area of ​​the waste liquid, which helps to further increase the evaporation rate and further reduce energy consumption. The speed-increasing structure can increase the air velocity at the gas-liquid interface, which can further increase the evaporation rate. The evaporation rate is faster, saving time and effort, with less energy loss, high energy utilization rate, and low energy consumption, thus improving the practicality of the low-temperature evaporation and drying device for high-concentration hazardous waste liquid.
