Solution Overview

Problem

Existing vapor condenser designs integrated into columns face limitations due to pressure loss issues, particularly in high-vacuum applications, as they deflect vapor rising from the column, causing undesirable pressure drops.

Innovation Solution

A device with a vapor space and a condensation space adjacent in the horizontal direction, where the vapor space is open at the bottom and the condensation space is closed, featuring a vertically aligned bundle of heat exchanger elements and deflection elements that redirect steam flow horizontally onto the heat exchanger elements, reducing pressure loss by minimizing deflection angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vapor is deflected at the top of the column to flow through the condenser, then condensation function is achieved, but pressure loss increases

Engineering Contradiction:
Improvecondensation functionVSAvoidpressure loss
Core Design Contradiction:
ReliabilityVSStress or pressure

Solution Approach 1:

Instead of deflecting vapor flow to pass through the condenser (conventional approach), the invention inverts the approach by allowing vapor to flow freely upward and condensing it through heat exchange surfaces positioned in the vapor path without causing flow deflection. The condenser is integrated such that heat exchange surfaces extend into the vapor space, enabling condensation without disrupting the upward vapor flow pattern.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention transitions from a horizontal/vertical deflection-based condensation approach to a three-dimensional integration where heat exchange surfaces are positioned to intercept vapor flow in the vertical upward direction. The condenser components are arranged in multiple levels and orientations within the column, allowing vapor to be condensed along its natural upward path without dimensional deflection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If vapor flow is deflected through the condenser, then condensation occurs, but turbulence increases

Engineering Contradiction:
Improvecondensation processVSAvoidturbulence
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

Rather than forcing vapor to change direction to reach condensation surfaces, the invention positions condensation surfaces to intercept vapor in its natural upward flow. The heat exchange surfaces are arranged to be perpendicular or at small angles to the vapor flow direction, minimizing turbulence generation while maintaining effective condensation.

Inventive Principle:
Principle #13The other way round (Inversion)

3Volume of moving object

If a compact integrated condenser is used, then installation space is reduced, but pressure loss increases

Engineering Contradiction:
Improveinstallation spaceVSAvoidpressure loss
Core Design Contradiction:
Volume of moving objectVSStress or pressure

Solution Approach 1:

The condenser components are nested within the column structure, with heat exchange surfaces positioned concentrically or in layered arrangements within the vapor space. This nesting allows the condenser to occupy minimal additional volume while maintaining sufficient surface area for condensation without restricting vapor flow paths.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention utilizes three-dimensional space within the column by positioning heat exchange surfaces at multiple vertical levels and radial positions. This spatial distribution allows compact integration while maintaining open vapor flow paths, as the surfaces are arranged to intercept vapor without creating flow bottlenecks.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
