According to reports, for the annual production of 100,000 tons of aqueous solution full-cycle urea process system, using this patented technology to transform the urea synthesis section, the carbon dioxide conversion rate can be increased by more than three percentage points, the annual savings of steam costs about 1.5 million - 2 million yuan, and brings obvious energy-saving benefits for the separation, concentration, return and other systems of the entire installation.
It is reported that the core of this patented technology is to be able to atomize large flow and high pressure liquids to 100-350 microns in a small space and mix with gaseous media to form a mixture similar to "homogeneous". It can solve the problem of material mixing in urea synthesis towers, and can also be applied under other similar conditions.
The researcher Liu Xiaodi, the patent holder of the invention patent, introduced that in the aqueous solution full-cycle urea production process, various measures are usually taken in the urea synthesis tower to improve the material mixing process and reaction process to increase the synthesis efficiency of the urea synthesis tower (CO2 Conversion rate), its fundamental approach is to solve the problem of material mixing under conditions of high pressure, large flow, and small space. If the three materials entering the synthesis tower, namely liquid ammonia, liquid methylamine solution, and gaseous carbon dioxide, are well mixed to form a "homogeneous" stream and then enter the synthesis tower, the mixing in the urea synthesis tower will be achieved. The problem is completely solved. At the same time, in any section of the synthesis tower, the speed, temperature, concentration, and density of the material are completely uniform. This prevents back mixing of the materials and ensures the reaction efficiency of the synthesis tower.
The automatic self-cleaning filter is a highly efficient filtration system that is widely used in water treatment, paint, and food grade industries. It is designed to remove impurities and particles from liquids and gases, ensuring that the final product is of the highest quality.
The self-cleaning filter operates by blocking impurities on the inner wall of the filter element, allowing only clean product to flow out from the outlet. This ensures that the product is free from contaminants and meets the required standards.
When the pressure difference of the self-cleaning filter reaches a preset value or cleaning time, or when manually operated, the filter will start the self-cleaning process. This process involves opening the automatic drain valve on the self-cleaning filter and activating the motor to drive the cleaning brush in the filter screen. The impurities blocked by the filter screen are discharged from the drain valve, and the system continues to flow during the cleaning process.
The entire operation of the self-cleaning filter is controlled by a PLC screen control panel. The control mode can be set to differential pressure, time, or manual, depending on the specific requirements of the application.
The self-cleaning filter is a reliable and efficient filtration system that ensures the quality and purity of the final product. It is easy to operate and maintain, and it can be customized to meet the specific needs of different industries and applications. With its advanced technology and superior performance, the self-cleaning filter is a valuable asset to any production process.
