A concentrated water treatment device for methanol-to-olefins (MTO) belongs to the field of methanol-to-olefins technology. The concentrated water treatment device consists of a wastewater stripping system, a concentrated water recycling system, and a concentrated water treatment system. The wastewater stripping system comprises a water mixing tank, a wastewater feed pump, inlet and outlet heat exchangers, a wastewater stripping tower, a reboiler, and a purified water pump. The concentrated water recycling system comprises a cooler, a reflux tank, and a concentrated water reflux pump. The concentrated water treatment system comprises a concentrated water storage tank, a mixed oil tank, and a mixed oil delivery pump. This invention adds a concentrated water treatment system, allowing the treated concentrated water to be returned to the system for further recycling, while the generated mixed oil is delivered externally, improving the economic efficiency of the unit. It optimizes the wastewater stripping tower system process, ensuring the stripping effect of the wastewater stripping tower and reducing energy consumption. The treated concentrated water ensures the quality of the purified water, meeting the water requirements of downstream units. It reduces the amount of grease generated in the alkaline washing tower of the separation unit, indirectly reducing the amount of grease inhibitor injected.

This invention provides a membrane solution container, a coating device, and a coating method for an implantable sensor. The membrane solution container has a membrane solution tank including an edge region and a central region for holding the membrane solution. The central region is for immersing the implantable sensor. The edge region is connected to the central region and extends outward around the central region. The bottom wall of the edge region is higher than the bottom wall of the central region's immersion tank, and the height difference between the bottom wall of the edge region and the bottom wall of the immersion tank is less than the coating depth setting value of the implantable sensor. This makes the membrane solution tank equivalent to a stepped expansion around the perimeter compared to existing membrane solution tanks. The implantable sensor is immersed in the central region's immersion tank for coating, thereby avoiding or even eliminating the influence of surface tension on the coating depth. Furthermore, the immersion tank of the membrane solution container has several protrusions inside, which can reduce the amount of membrane solution used while ensuring the same coating depth and coating quantity.

The re-humidification and atomization system of the re-humidification zone of the tobacco sheet re-drying machine of this utility model includes: a re-humidification zone 1, a re-humidification zone 2, a re-humidification zone 3, a main conveyor belt, a first water tank, a second water tank, a first water pump, and a second water pump. The re-humidification zones 1, 2, and 3 are placed sequentially. The main conveyor belt passes through the main housing of the re-humidification zones 1, 2, and 3 sequentially. The high-temperature condensate recovery pipe is connected to the first water tank through a first automatic switch valve. Hot water and cold water are mixed in the second water tank and then sent to the re-humidification zones 1, 2, and 3 through the main re-humidification humidification pipe and the second pump humidification branch pipe. In the second water tank, the water tank is divided into upper and lower parts by a partition. The cold water pipe enters the upper part of the partition, and a mixing water pipe is set below the partition. Cold water enters the mixing water pipe from the cold water pipe, and hot water from the first water tank extends into the mixing water pipe of the second water tank. Small water outlet holes are evenly distributed in the part of the hot water pipe in the mixing water pipe.
