Description

Technical Field

[0001] The utility model relates to the technical field of ultra-high pressure nozzles, and particularly relates to a combined tooling capable of flushing in both forward and reverse directions. Background Technique

[0002] There are 6 catalyst injection points in the reactor of the EVA device in Gulei Petrochemical, which are in the form of nozzles (nozzle aperture 0.20mm), and the injected catalyst participates in the reaction. Especially during the start-up stage of the device, especially during the trial production stage of a newly built device, there are many system impurities, which are extremely likely to cause nozzle blockage. Or during the production process, due to various operating parameters such as temperature, pressure, catalyst batch, and grade change, the nozzle is blocked by polymers and cannot continuously inject catalyst, resulting in the shutdown of the device. It is necessary to remove the nozzle in time for dredging to resume production. The polymer powder is difficult to remove due to the small diameter of the nozzle. A variety of methods have been tried, such as soaking and dissolving with organic solvents, removing with ultrasonic vibration, purging with a wind pipe, inserting a thin welding wire for dredging, etc. The effects are uneven and the time is uncertain. The above cleaning and dredging methods are not ideal. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model provides a combined tooling capable of flushing in both forward and reverse directions to solve the problem that it is difficult to quickly and effectively clean the blocked nozzle in the existing device.
