用于1.2丙二醇水合生产的多效节能蒸汽回用装置
By employing a differential-driven threaded knob and spring-loaded mechanism and a rotating flared section design, the problems of insufficient steam heat recovery and low condensate separation efficiency in the hydration production of 1,2-propylene glycol were solved. This enabled the cascade recovery of steam heat and the self-collection of high-purity condensate, thereby improving the system's energy-saving effect.

AI Technical Summary
In the current 1,2-propylene glycol hydration production process, the final-effect secondary steam is directly discharged into the air or the condensate is not fully collected, resulting in the loss of residual heat. Uneven pressure distribution leads to heat transfer and temperature difference loss, and the residual raw materials in the steam are not fully collected, resulting in a gap between the system's energy-saving effect and the theoretical value.
The differential-driven threaded knob and spring-loaded mechanism, combined with the rotating flared section and collection ring system, achieves efficient steam condensation and centrifugal collision. The support and rotating ring design ensures continuous and stable steam output, enabling cascaded recovery of steam heat and self-collection of high-purity condensate.
It improves the efficiency of steam heat recovery and enhances the separation efficiency of condensate, achieving an integrated energy-saving effect of steam heat recovery in stages and high-purity condensate self-collection.

Abstract
Claims
1. A multi-effect energy saving steam reusing device for 1.2 propylene glycol hydration production, characterized in that, The utility model relates to a steam condenser, comprising: a base plate, one side of which receives steam; a connecting pipe, which is circumferentially arranged on the base plate and guides steam into its internal cavity, and comprises a break; a driving source, which drives the connecting pipe to rotate around the axis of the base plate above the break; a threaded knob, which is arranged at the break of the connecting pipe and forms a complete guiding channel with the connecting pipe; a spring plate, which is horizontally arranged on the side of the threaded knob in the guiding channel and has: a pressing groove, which is opened on the spring plate and makes the spring plate have a tendency to deform in the direction of the pressing groove; springs, which are arranged on both sides of the spring plate in the pressing groove; wherein, when the connecting pipe rotates, the threaded knob deforms in steps due to differential speed and presses the spring plate to deform in the direction of the pressing groove, so that the springs are fan-shaped bent, and steam forms condensate at the bent part and collides with rising steam under the action of centrifugal force.
