Description

Technical Field

[0001] This utility model relates to the field of separation device technology, specifically to a high-salt wastewater crystallization separation device. Background Technology

[0002] High-salinity wastewater treatment utilizes thermal and membrane separation crystallization technologies to precisely separate sodium chloride and sodium sulfate, achieving zero discharge and resource recovery. Thermal processes leverage concentration differences and temperature control, while membrane processes employ nanofiltration and electrodialysis to enhance purity. Facing environmental challenges, technological innovation is driving breakthroughs in both energy conservation and economic benefits, paving new paths for sustainable development. The treatment of saline wastewater from chemical plants is a challenging aspect of wastewater treatment. Conventional treatment of saline wastewater using steam triple-effect separators suffers from drawbacks such as easy clogging, high maintenance costs, and high operating expenses. Some manufacturers directly treat saline wastewater as hazardous waste, resulting in significant economic waste.

[0003] However, in implementing the relevant technology, the following problems were found in the existing technology: it is difficult to filter impurities from high-salt wastewater, resulting in a large number of internal impurities after crystallization, which affects the later use; and it is difficult to achieve the purpose of continuous evaporation and crystallization of high-salt wastewater, thereby reducing the working efficiency of high-salt wastewater crystallization and separation. Therefore, a high-salt wastewater crystallization and separation device is proposed. Utility Model Content

[0011] The feeding mechanism is mounted on the rotating mechanism;

[0012] Multiple drainage holes, arranged in a circular array, are formed throughout the outer side wall of the inner liner.

[0013] A circular filter cylinder is disposed on the inner side wall of the inner tank;

[0014] A scraper is fixedly installed on the outer side wall of the inner tank and contacts the inner side wall of the evaporator.

[0015] Preferably, the rotating mechanism includes a motor fixedly mounted on the top of the outer can and a gear fixedly connected to the output end of the motor;

[0016] A hollow sealed tube runs through the outer tank, evaporator, and inner tank, and a gear two is fixedly connected to the top of the hollow sealed tube. The gear two is meshed with the gear one.

[0017] Preferably, the feeding mechanism includes a water pump fixedly installed on the top of the outer tank, a feed pipe fixedly connected to the input end of the water pump, and a rotary joint fixedly connected to the output end of the water pump, the bottom end of the rotary joint being fixedly connected to the top end of the hollow sealing tube;

[0018] Multiple nozzles are fixedly installed on the outer wall of the hollow sealing tube.

[0019] Preferably, an exhaust pipe is fixedly connected to the top of the evaporator, and the top of the exhaust pipe passes through the top of the outer tank.

[0020] Preferably, a discharge pipe is fixedly connected to the bottom end of the evaporator, and the bottom end of the discharge pipe passes through the bottom end of the outer tank.

[0022] The working principle and beneficial effects of this utility model are as follows:

[0023] The high-salt wastewater is fed into the high-salt wastewater tank via a feed pipe. A pump is then activated to extract the high-salt wastewater from the external tank. The extracted wastewater is transported through a rotary joint to the interior of a hollow sealed tube and sprayed from multiple nozzles. A motor drives gear one, which in turn pulls gear two, causing the hollow sealed tube to rotate. This rotation of the inner tank within the evaporator allows the high-salt wastewater inside to pass through a circular filter cylinder and be ejected through multiple drain holes, achieving the purpose of filtering impurities from the high-salt wastewater. The ejected wastewater contacts the inner tank, which is heated by a threaded heating element, and evaporates instantly. Salt residue remains on the inner wall of the evaporator. A rotating scraper removes this salt residue, effectively separating the salt wastewater through crystallization, thus improving separation efficiency. Attached Figure Description
