Rectangular Gas Liquid Trap with Asymmetric Filter Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid trap devices for gases face performance degradation due to captured liquids being carried to the gas outlet, requiring a large diameter to ensure sufficient lateral distance, which increases device dimensions and complicates efficient liquid capture.
Innovation Solution
A liquid trap device with a trap housing shaped long along the laterally central line, featuring a filter element and outflow guide tube positioned near side wall portions, an inflow guide tube projecting into the filter element, and a stagnant portion around the outflow guide tube, all integrally molded with synthetic resin, to ensure a sufficient distance and prevent liquid from reaching the gas outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trap housing is formed with a sufficiently large diameter to guarantee sufficient lateral distance from the filter element to the gas outlet, then liquid capture performance is improved, but the dimensions of the liquid trap device increase
Solution Approach 1:
The patent transitions from a conventional cylindrical trap housing to a rectangular prism-shaped housing, utilizing the length dimension along the laterally central line to provide sufficient distance between the filter element and gas outlet. This dimensional change allows liquid to fall before reaching the outlet without requiring a large diameter, thus maintaining compact overall device dimensions while ensuring effective liquid capture.
Solution Approach 2:
The patent positions the filter element and gas outlet asymmetrically within the rectangular trap housing, with the filter element located near one end and the gas outlet at the opposite end along the laterally central line. This asymmetric arrangement maximizes the lateral distance between these components, providing sufficient space for liquid to fall while maintaining a compact housing design.
2Volume of moving object
If the filter element and gas outlet are positioned close together to reduce device dimensions, then compact size is achieved, but liquid captured by the filter element is carried to the gas outlet by gas flow
Solution Approach 1:
The rectangular prism-shaped trap housing utilizes the length dimension to create sufficient separation distance between the filter element and gas outlet along the laterally central line. This allows compact cross-sectional dimensions while maintaining adequate longitudinal distance for liquid to fall before reaching the outlet, preventing liquid carryover.
Solution Approach 2:
The patent creates a stagnant portion in the internal space where gas flow velocity is reduced before the gas reaches the gas outlet. This preliminary deceleration allows liquid droplets to separate from the gas flow and fall to the bottom of the trap housing before the gas exits, preventing liquid from being carried out with the gas.
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 configuration allows for efficient separation and falling of liquids, preventing them from reaching the gas outlet, achieving a balance between compact size and improved liquid capture performance while prolonging filter element service life and preventing local saturation.
Implementation Method 1
a filter element that is retained between the ceiling wall and the bottom wall, an interior of the filter element communicating with the gas inlet port and an outer peripheral face of the filter element communicating with the gas outlet port via an internal space of the trap housing, and when gas flowing from the gas inlet port toward the gas outlet port passes through the filter element, a liquid contained in the gas is captured by the filter element
Implementation Method 2
a stagnant portion around the outflow guide tube where gas becomes stagnant, and the ceiling wall, the peripheral wall, the inflow guide tube, and the outflow guide tube are integrally molded together with a synthetic resin as a material

AI summary
A liquid trap device for a gas is provided which includes a trap housing (3) that is formed from a ceiling wall (5), a bottom wall (6) and a peripheral wall (7), the ceiling wall (5) having provided therein a gas inlet port (20) and a gas outlet port (21), and a filter element (4) that is retained between the ceiling wall (5) and the bottom wall (6), the interior of the filter element (4) communicating with the gas inlet port (20) and the outer peripheral face of the filter element (4) communicating with the gas outlet port (21) via an internal space (8) of the trap housing (3), wherein the trap housing (3) is formed as a shape that in plan view is long along one laterally central line (X), and the filter element (4) and an outlet port upstream portion (21a), opening within the trap housing (3), of the gas outlet port (21) are disposed in proximity to first and second side wall portions (7a, 7b) respectively of the peripheral wall (7) facing each other on the laterally central line (X). This enables a liquid trap device for a gas to be provided in which a sufficient lateral distance from a filter element to a gas outlet can be guaranteed while having small dimensions and the performance in capturing a liquid can be enhanced.
