Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas scrubbers are inefficient in separating particles from gases and require large spaces due to external structural support, limiting their compactness and separation efficiency.
Innovation Solution
A two-stage method and wet scrubber design that utilizes a swirl generator and vertical cylindrical separation space for cyclonic separation, eliminating the need for external structures and allowing adjustable liquid levels to enhance separation efficiency, with the venturi channel integrated within the cylindrical vessel for compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If external steel structures are used to carry the wet scrubber, then structural strength and stability are ensured, but the device occupies more space and becomes less compact
Solution Approach 1:
The patent merges the support function into the scrubber's own structure by making the cylindrical vessel wall self-supporting through optimized wall thickness and structural design. The vessel wall itself carries the operational loads and self-weight, eliminating the need for separate external steel support structures, thereby reducing overall space occupation while maintaining required structural strength.
Solution Approach 2:
The scrubber structure is designed to support itself through its own cylindrical vessel wall, which is engineered with sufficient thickness and structural characteristics to bear the device's self-weight and operational loads without requiring external assistance from separate support structures.
2Ease of operation
If a duct is used to connect the venturi channel and the cylindrical separation space, then gas flow path is established, but the device becomes larger and less compact
Solution Approach 1:
The patent merges the venturi channel and cylindrical separation space into a single integrated vessel structure. The venturi channel is positioned within or directly connected to the cylindrical separation space without requiring external ductwork, allowing gas flow to transition directly between functional zones through the vessel's internal geometry, thereby eliminating the need for separate connecting ducts and reducing overall device size.
Solution Approach 2:
The venturi channel is nested within or directly integrated into the cylindrical separation space, with the gas flow path established through the internal geometry of the single vessel structure, eliminating the need for external ductwork and reducing device footprint.
3Productivity
If the liquid level in the liquid tank is increased to improve separation efficiency, then cyclonic action and separation efficiency increase, but the risk of liquid overflow and equipment damage increases
Solution Approach 1:
The patent incorporates a liquid level sensing and control system that continuously monitors the liquid level in the liquid tank and provides feedback to the liquid supply mechanism. When the liquid level approaches a predetermined safe threshold, the system automatically reduces or stops liquid supply to prevent overflow, while still maintaining sufficiently high liquid levels to ensure effective cyclonic action and separation efficiency during normal operation.
Solution Approach 2:
The system establishes a safety margin by setting the maximum liquid level below the overflow point, creating a buffer zone that prevents liquid from reaching dangerous levels. The liquid level control mechanism proactively prevents overflow conditions before they can occur, protecting the equipment from damage while maintaining optimal separation efficiency.

AI summary
The invention relates to a method and to a wet scrubber for removing particles from gas. The wet scrubber comprises a second vertical cylindrical vessel (10) having a second upper end (11) for receiving an accelerated stream of liquid- and particles-laden gas (25) from a vertically oriented venturi channel (2) and a second lower end (12) for feeding the accelerated stream of liquid- and particles-laden gas (25) to a swirl generator (3). The second vertical cylindrical vessel (10) and the swirl generator (3) are arranged in a vertical cylindrical separation space (5) of a first vertical cylindrical vessel (6). The swirl generator (3) is arranged above the liquid tank (13).
