Jilin Petrochemical Company's chemical fertilizer plant targeted the bottleneck problem of safe production, such as desulfurization and purification of syngas equipment, and often used to block towers. It adopted measures such as expanding the gas-phase passage in the desulfurization tower to eliminate hidden dangers and ensure long-term safe and stable operation of the equipment. On August 4th, the chemical fertilizer plant performed a test on the operation status of the window of the technical renovation project after the vehicle was overhauled and the result was good.
According to the actual operation situation, the chemical fertilizer research team focused on the fact that sulfur occlusion occurred mostly in the airways. After repeated research and experiments, the organization personnel dismantled the gas phase grid holes, expanded the gas-phase channels in the desulfurization tower, and accumulated sulphur o The overflow weir was modified and a flushing port was added to flush the accumulated sulfur paste. On this basis, the research team to strengthen filtration, increase the frequency of inverted tank filtration and other means to ensure that the system suspended sulfur is normal. At the same time, by adjusting the alkalinity and temperature of the solution, the system resistance is reduced, the plugging condition in the tower is effectively eliminated, and the resistance is returned to the normal index, ensuring that the process indicators of the desulfurization process are controlled.

Our Wood Force Control System, wood active contact flange, wood Constant Force Actuator have many advantages over other grinders. It can realize flexible grinding, quick repsond to surface changing, and instant adjusting. Traditional mechanic hand lacks flexibility, and it is not easy to adjust, hard to realize mass production.
