Embodiment Construction

[0007] In the specific implementation process, the original fixed nozzle was changed into a movable nozzle, the original hard pipe was changed into a metal hose, and a ball valve was installed at the bottom, so that when cleaning and dredging the final polycondensation spray ethylene glycol nozzle, it can be connected with the final polycondensation nozzle. Vacuum system isolation. After the isolation is confirmed, the nozzle can be removed from the sprinkler. Clean and install. Then merge into the system. This technology can be widely used in the actual operation of polyester production.

Abstract

A movable type final polycondensation spray ethylene glycol nozzle is provided, which meets the spray ethylene glycol amount of the final polycondensation sprayer. The invention adopts the movable nozzle and changes the original rigid tube to the metal hose, and installs a ball valve additionally on the bottom end. Under the condition that the final polycondensation vacuum system is separated, the movable nozzle is used and is taken off from a spray system; after washing cleanly, the nozzle is installed again with convenient operation and complete washing and without effect on the vacuum degree of the final polycondensation system. Besides, the nozzle is widely applied in the actual operation of the polyester production.

Description

technical field [0001] The invention relates to a movable nozzle, in particular to a movable nozzle used in the final polycondensation spraying of ethylene glycol in a polyester device. Background technique [0002] In polyester production, due to the reaction characteristics, the vacuum degree of the final polycondensation system is relatively high, and the amount of ethylene glycol sprayed by the final polycondensation sprayer must meet the process requirements. The reasons that affect the amount of spraying glycol in the final polycondensation sprinkler include the working condition of the final polycondensation spray glycol supply pump, the blockage of the final polycondensation spray glycol blue filter, and the blockage of related delivery pipes. In addition to the situation, the most prone to failure is the nozzle of the final polycondensation spray ethylene glycol. To unclog the glycol spray nozzle during the operation of the device, one must operate very carefully t...
