Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil loading systems generate volatile organic compounds (VOCs) during the oil loading process in storage tanks, leading to environmental pollution and oil loss, due to pressure drops that cause evaporation, and require significant space for installation with wider transverse cross-sections.
Innovation Solution
An oil loading apparatus with a vertical loading pipe and a pressure drop module that includes a pressure drop pipe with multi-hole orifices and a T-shaped branch pipe, along with a mesh part and a cylindrical chamber, which induces a controlled pressure drop and spirals the oil flow to reduce VOC generation, while maintaining a higher pressure inside the loading pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a loading column with a transverse cross-section wider than the supply pipe is used to reduce VOC generation, then VOC generation is reduced, but installation space requirement increases
Solution Approach 1:
The invention changes the flow pattern from horizontal to vertical by installing the loading column vertically in the storage tank. This dimensional change allows the system to achieve effective VOC prevention through vertical flow control and pressure management without requiring increased horizontal installation space, thus resolving the contradiction between VOC reduction and space requirement
Solution Approach 2:
The invention changes the pressure parameter within the loading column by controlling the oil flow rate and using a pressure control device. By maintaining appropriate pressure levels and avoiding excessive pressure drops, the system prevents VOC generation without needing a wider transverse cross-section, thereby resolving the contradiction between VOC reduction and installation space
2Productivity
If oil is loaded quickly to improve productivity, then loading efficiency increases, but pressure drop increases causing VOC generation
Solution Approach 1:
The invention employs a pressure control device that monitors and adjusts the oil flow rate in real-time during loading operations. This feedback mechanism ensures that the loading speed is optimized to maintain appropriate pressure levels, preventing excessive pressure drops and VOC generation while still achieving high loading efficiency, thus resolving the contradiction between productivity and VOC prevention
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
The solution effectively reduces the generation of VOCs by maintaining a higher pressure inside the loading pipe, minimizing evaporation and environmental impact, and allows for a more compact design by optimizing the flow pattern and pressure drop mechanism.
