Technical Field

The invention belongs to the technical field of condensers, and particularly relates to a spiral condensing piece.

Background

The spiral plate condenser is formed by rolling two parallel metal plates into spiral flow channels which are separated from each other. The spiral flow passages which are separated from each other are respectively a cooling water flow passage and a condensed material flow passage, the cooling water flow passage is used for conveying cooling water, and the condensed material flow passage is used for conveying materials to be condensed. And the material to be condensed enters from a gas-phase material inlet at the side part of the condenser, flows to the center of the condenser along a spiral condensed material flow channel and is finally discharged from a condensed material outlet at the bottom of the condenser. The cooling water enters from a cooling water inlet at the bottom of the condenser and finally flows out from a cooling water outlet at the upper side end of the condenser. The adjacent and separated materials to be condensed and cooling water exchange heat through the metal plate between the two. But because the height of cooling water runner is highly relevant with the self of condenser, the flow of cooling water on the vertical direction is comparatively chaotic and irregular in the cooling water runner simultaneously to lead to the inside temperature instability of condenser easily, and then reduced the holistic condensation effect of condenser.
