Parallel Gas Treatment Facility for High Flow Rate Heat Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas treatment technologies face limitations in achieving high energy yield and flow rates due to inefficient heat exchange and increased device size when trying to maintain efficiency at higher gas flow rates, especially with direct contact methods in exchange enclosures.
Innovation Solution
A facility with multiple treatment devices, each containing an exchange enclosure with a liquid bath and connected aeraulic means that create a pressure difference to introduce and treat gas streams through the liquid, allowing for simultaneous and parallel operation to achieve high flow rates without compromising efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cross sectional enclosure area is increased to maintain heat transfer efficiency at higher gas flow rates, then the heat transfer efficiency is maintained, but the overall size of the device increases excessively
Solution Approach 1:
The invention divides a single large exchange enclosure into multiple smaller exchange enclosures (at least two) that operate in parallel. Each enclosure has its own liquid bath and injection conduit system. This segmentation allows the total gas flow rate to be distributed across multiple smaller units, maintaining heat transfer efficiency without requiring a single large enclosure that would increase device size excessively.
2Productivity
If the volume of liquid in the exchange enclosure is increased to maintain heat transfer efficiency, then the heat transfer efficiency is improved, but the efficiency is lost due to edge effects at the walls above a certain gas flow rate
Solution Approach 1:
By segmenting the system into multiple smaller exchange enclosures, each with its own optimized liquid volume, the invention avoids the edge effects that occur in single large enclosures. Each small enclosure maintains optimal liquid-to-gas contact ratios without the detrimental wall effects that plague larger single enclosures at high flow rates.
Solution Approach 2:
The invention transitions from a single large enclosure operating in one dimension to multiple smaller enclosures operating in parallel (adding a dimensional aspect of parallelism). This allows the system to handle higher total gas flow rates while each individual enclosure maintains optimal heat transfer characteristics without edge effects.
3Loss of energy
If direct contact heat exchange methods are used to achieve high energy yield, then energy efficiency is improved, but the gas flow rate is limited due to inefficient heat exchange at higher rates
Solution Approach 1:
The invention segments the gas flow into multiple parallel streams, each passing through its own injection conduit and exchange enclosure. This allows direct contact heat exchange to be maintained at optimal ratios for each stream, preserving high energy yield while the cumulative effect of multiple parallel streams achieves the desired high total gas flow rate.
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
Enables high flow rates exceeding 10,000 m3/h with consistent treated gas stream quality, reducing the overall size of the device and maintaining efficient heat transfer by maintaining identical initial liquid levels across exchange enclosures.
Implementation Method 1
aeraulic means, which are connected to all the discharge openings of the exchange enclosures or which are connected to all the intake openings of the injection conduits, and which, during operation, make it possible to create, by suction or blowing, simultaneously and in parallel for each treatment device, an incoming gas stream
Implementation Method 2
The use of a liquid, for example water, to treat, and in particular to heat or cool, a gas stream by heat exchange between the liquid and the gas stream, with placement of the gas stream and the liquid in direct contact
Implementation Method 3
an outgoing gas stream, treated by direct contact with said liquid bath, rises up inside the exchange enclosure and is discharged out of said exchange enclosure

AI summary
The facility (1A) includes at least two treatment devices (2) each with an exchange chamber (20) intended to contain a liquid bath in the bottom part and at least one injection line (21). An aeraulic means (4), creates by suction or by blowing, simultaneously and in parallel for each treatment device (2), an incoming gas stream (F) originating from outside the exchange chambers (2) and passes through the discharge opening of the injection line (21) by being introduced into the liquid bath contained in the bottom part of the exchange chamber (20), below the surface (S) of said liquid bath. The exchange chambers (20) communicate hydraulically with one another so that when the aeraulic means (4) are shut down, each exchange chamber (20) is suitable for containing or contains, in the bottom part, an initial volume (Vinitial) of liquid, with an initial liquid level (Hinitial) that is identical in all the exchange chambers (2).
