Ring-Shaped Tank Scrubber Tower for Reduced Piping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional scrubber systems with multiple stages require extensive piping and external tank arrangements, leading to inefficiencies and increased demands on pumps due to the need for large volumes of fluid handling and storage, especially in tall tower configurations.
Innovation Solution
The scrubber stages are arranged vertically within a tower with ring-shaped tanks integrated inside the tower, allowing gas to rise through central channels while ring-shaped tanks collect and recirculate fluid, reducing the need for external tanks and minimizing piping lengths by integrating pumps and tanks within the scrubber structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external tanks are used for each scrubber stage, then fluid collection and storage is ensured, but piping complexity and pump demands increase
Solution Approach 1:
The patent applies nesting by placing the tank inside the scrubber tower structure itself. The tank is positioned within the tower's internal space, surrounded by the tower wall on the outside and the central channel on the inside, eliminating the need for external tank installations and reducing piping complexity.
Solution Approach 2:
The patent merges the tank with the scrubber tower structure by integrating the tank within the tower's internal volume. This combination allows the tower to serve dual purposes: as the scrubbing chamber and as the housing for fluid collection and storage, thereby reducing overall system complexity.
2Quantity of substance
If external tanks are used for each scrubber stage, then fluid storage capacity is sufficient, but the footprint of external infrastructure increases
Solution Approach 1:
The tank is nested within the scrubber tower's internal volume, utilizing the vertical space already allocated for scrubbing operations. This eliminates the need for separate external tank foundations and reduces the horizontal footprint of the overall system.
3Productivity
If pumps are positioned to handle large fluid volumes from external tanks, then fluid circulation is maintained, but pump power requirements increase
Solution Approach 1:
The patent positions the pump at the bottom of the tower where the tank is located, allowing the pump to draw fluid from a low elevation point. The tower structure itself provides the elevation head, reducing the vertical lift distance the pump must overcome and thereby lowering power requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces piping complexity, lowers the demands on pumps, and optimizes fluid handling by integrating tanks and pumps within the scrubber tower, enhancing operational efficiency and reducing the footprint of external infrastructure.
Implementation Method 1
The process fluid and the gas are in this way brought into contact with each other, whereby certain components that are present in the gas, such as, for example, HCl, SO2, and HF, are absorbed in the process fluid.
Implementation Method 2
ring-shaped tanks integrated inside the tower, allowing gas to rise through central channels while ring-shaped tanks collect and recirculate fluid

AI summary
A scrubber for the cleaning of gases containing several scrubber stages (1-4), where the scrubber stages are arranged in a scrubber tower with the different stages at different levels above each other in the scrubber tower. At least one of the scrubber stages (2-4) above the lowest scrubber stage (1) comprises, according to the invention, a ring-shaped tank (10, 15, 20) arranged inside the scrubber tower, which ring shaped tank (10, 15, 20) is arranged surrounding a central channel (9, 14, 19) through which the gas that is to be cleaned can pass upwards.
