Recently, Henan Jiuye Chemical Equipment Co., Ltd. has secured 4 utility model patents, focusing on core technologies for sodium aluminate solution concentration and tubular falling film evaporators, injecting new momentum into the innovation of the chemical equipment industry!
In the concentration of sodium aluminate solution, two major industry pain points exist: difficulty in cleaning crystals on the inner walls of heat exchange tubes and inconvenience in maintaining traditional equipment. This patent solves these problems through dual innovations:
First, it adopts a linkage between the drive motor and the cleaning plate—using a special wear-resistant material to scrape off crystals. It can also monitor the crystal thickness in real time and automatically adjust the cleaning frequency, ensuring the efficient operation of the equipment.
Second, it features a split-type modular design. Components can be independently disassembled, assembled, and connected via standardized interfaces, adapting to different site requirements. This design reduces fault diagnosis time by more than 60% and cuts maintenance costs by 40%, achieving the dual value of "crystal prevention + easy maintenance".
Foam in tubular falling film evaporators easily causes pipeline blockage and reduced evaporation efficiency. This device breaks through this bottleneck with a "triple-design" approach:
? The flange is compatible with interfaces of multiple specifications. Hydraulic automatic calibration enables quick connection in 45 seconds, with efficiency 6 times higher than that of traditional methods.
? The "double hood + negative pressure" technology collects foam. A negative pressure airflow of 12 m/s sucks the foam into the conical shell, and a sudden pressure change within 0.3 seconds achieves a 98% defoaming rate.
? A high-temperature resistant liquid guide hose, combined with intelligent liquid level monitoring, adjusts the liquid return speed adaptively, reducing material loss by 15% and ensuring continuous production.
When traditional seven-effect evaporators handle high-concentration sodium aluminate solution, they require temperature increase or equipment expansion, leading to a sharp surge in investment. This patent balances energy efficiency and economy through "pre-heating + integrated series connection":
? The pre-heating mechanism controls temperature precisely, heating the solution to the pre-evaporation temperature in advance and reducing steam consumption by 15%-20%.
? Seven evaporators are connected in an integrated series, which reduces heat loss and increases the heat recovery rate by over 30%. With a daily processing capacity of 1,000-ton level, it meets the needs of large-scale concentration.
Traditional seven-effect tubular evaporators have a fixed liquid film thickness in heat exchange tubes, making high-concentration solutions prone to crystallization and blockage. The core of this patent is the "conical plug adjustment system":
? An electric push rod drives the conical plug to rise and fall, controlling the inlet gap of the heat exchange tube. For high-concentration solutions, the liquid film is thinned to prevent crystallization; for low-concentration solutions, the liquid film is thickened to improve efficiency.
? Seven evaporators are connected in series, using steam from the previous effect as the heat source for the next effect to realize cascade utilization of heat energy. Equipped with water pumps and coolers to ensure stable operation, it is suitable for industries such as pharmaceuticals and chemicals.
The approval of these 4 patents reflects Jiuye Chemical's "technology-driven" philosophy. The company has long been deeply engaged in R&D, identified industry pain points, and promoted technology transformation. In the future, Jiuye Chemical will continue to innovate, provide better equipment and services to customers, and contribute to the upgrading of the chemical equipment industry!
