1Area of stationary object
If the viscous substance is dropped from above onto the heat transfer pipes by gravity, then the absorbing liquid can be placed on the heat transfer pipes, but the contact area between the viscous substance and heat transfer pipes is limited due to high surface tension and poor wettability
Solution Approach 1:
A coating element with coating portions acts as an intermediary between the viscous substance and the heat transfer pipes. The coating element mechanically spreads the viscous substance onto the heat transfer pipes, overcoming the poor wettability caused by high surface tension. This mediator enables the viscous substance to cover a larger contact area on the heat transfer pipes without requiring improved wettability properties of the substance itself.
Solution Approach 2:
The patent replaces the simple gravitational dropping mechanism with a mechanical coating system. The coating element, driven by a driving source, mechanically applies and spreads the viscous substance onto the heat transfer pipes. This mechanical substitution overcomes the limitations of gravity-based application and poor wettability, achieving uniform and extensive coverage.

If the viscous substance is sprayed toward the heat transfer pipes by gravity, then the absorbing liquid can be contacted with vapor for dilution, but the dispersion and contact area are limited due to high viscosity
Solution Approach 1:
The coating element serves as a mediator that actively spreads the viscous substance across the heat transfer pipes. This mechanical spreading action overcomes the high viscosity that would otherwise limit natural dispersion. The coating element ensures the viscous substance forms a uniform film with maximum contact area, thereby enhancing dilution efficiency through improved vapor contact.
Solution Approach 2:
The coating element is designed to be movable, driven by a driving source to rotate or move along the heat transfer pipes. This dynamic mechanism allows the coating portions to continuously spread and redistribute the viscous substance, maintaining optimal contact area and dilution efficiency throughout the operation, rather than relying on static gravitational spraying.
3Productivity
If a mixing apparatus with rotating shaft and impelling means is used, then liquid can be diffused and mixed on coating surfaces, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential mixing function needed for the application, eliminating unnecessary complex components. Instead of using a full mixing apparatus with rotating shafts and multiple impelling means, the invention employs a simplified coating element with coating portions that performs the necessary spreading and mixing action on the coating surfaces, achieving adequate mixing efficiency with reduced structural complexity.
Solution Approach 2:
The coating element is designed with coating portions that are specifically configured for the local requirements of the heat transfer pipes. Rather than using a complex universal mixing system, the coating portions are tailored to match the geometry and surface characteristics of the heat transfer pipes, providing effective local spreading and mixing where it is most needed while minimizing overall device complexity.
