Chemical Synthesis Device Intermediate Container Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical synthesis devices face challenges in adjusting the supply and discharge of chemicals, leading to inefficiencies in reaction time and increased device size due to the need for high-output pressurizing and negative pressure means.
Innovation Solution
Incorporating an intermediate container with adjustable pressure between the reaction vessel and waste liquid tank allows for precise control of chemical flow without increasing the device's size, using pressure regulators and valves to manage pressure differentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the waste liquid tank is provided with pressurizing means and negative pressure means to adjust pressure differential and feed rate, then the chemical feed rate can be adjusted, but the device becomes bulkier due to the large volume required for the waste liquid tank
Solution Approach 1:
The patent divides the waste liquid management system into two separate components: a waste liquid tank for storage and an intermediate container for pressure adjustment. This segmentation allows the pressurizing and negative pressure means to be positioned on the intermediate container rather than the large waste liquid tank, enabling feed rate control without requiring high-output devices that would increase overall device size.
Solution Approach 2:
The intermediate container serves as a mediator between the reaction vessel and the waste liquid tank. By placing the pressurizing and negative pressure means on this intermediate container, the system can adjust pressure differentials and control chemical feed rates without needing to directly manipulate the large-volume waste liquid tank, thus avoiding the need for bulky high-output pressurizing devices.
2Duration of action of moving object
If chemicals are introduced in larger amounts to buy time for slow reactions, then reaction time is extended, but the supply amount cannot be precisely adjusted according to process requirements
Solution Approach 1:
The patent changes the pressure parameter of the intermediate container to control the feed rate of chemicals. By adjusting the pressure differential between the reaction vessel and the intermediate container, the system can precisely control the supply amount and duration of chemical feeding, allowing slow reactions to proceed over extended periods without introducing excessive amounts of chemicals.
3Reliability
If the reaction vessel is flushed with cleaning liquid for extended periods to ensure thorough cleaning, then cleaning effectiveness is improved, but the operating rate of the device is lowered
Solution Approach 1:
The patent uses pressure differential adjustment on the intermediate container to control the flow rate of cleaning liquid through the reaction vessel. This allows for rapid flushing that achieves thorough cleaning effectiveness while minimizing the time required, thereby maintaining high operating rates and productivity.

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 enables flexible adjustment of chemical feed rates and discharge flows, optimizing reaction time and reducing the overall device size by using smaller, more compact pressurizing and negative pressure devices.
Implementation Method 1
the pressure of the intermediate container is adjusted to adjust the flow supplied to the reaction vessel and the flow discharged from the reaction vessel
Implementation Method 2
an intermediate container having a smaller capacity than the waste liquid tank is provided between the reaction vessel and the waste liquid tank, via a waste liquid pipe, and the pressure of this intermediate container is adjusted
