Waste Carrying Container Steam Conducting Unit for Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waste stabilization processes, such as those for slag, face inefficiencies due to poor diffusion of steam, leading to inadequate mixing and stabilization of waste materials at the upper layers.
Innovation Solution
A waste carrying container equipped with a steam conducting unit featuring multiple steam tubes arranged at intervals, allowing high-pressure steam to be evenly and sufficiently mixed with the waste within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If steam is introduced from the bottom of the waste pile, then the lower layer waste can be stabilized, but the steam diffusion is blocked and upper layer waste cannot be sufficiently mixed
Solution Approach 1:
The steam introduction system is segmented into multiple independent steam tubes distributed throughout the waste pile, rather than a single bottom introduction point. This segmentation allows steam to be introduced at multiple locations simultaneously, improving both diffusion efficiency and distribution uniformity.
Solution Approach 2:
The steam introduction approach transitions from a one-dimensional bottom-up approach to a three-dimensional distributed approach. Steam tubes are positioned at various heights and locations within the waste pile, enabling steam to penetrate and mix with waste material throughout the entire volume, not just at the bottom layer.
2Quantity of substance
If multiple steam tubes are installed at spaced intervals, then steam can be evenly distributed throughout the waste pile, but the device complexity increases
Solution Approach 1:
The steam tubes serve multiple functions: they are both the structural framework for supporting the waste pile and the conduit for steam distribution. This multi-functionality reduces the need for separate support structures, thereby limiting the increase in device complexity despite the addition of multiple steam tubes.
Solution Approach 2:
The steam tubes are strategically positioned at specific intervals and heights where they are most needed for effective steam distribution. Rather than uniformly distributing tubes throughout the entire structure, they are placed at critical locations to maximize steam-waste contact efficiency while minimizing overall structural complexity.
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 ensures improved stabilization performance by ensuring uniform steam distribution throughout the waste pile, enhancing the conversion of unstable components into stabilized forms.
Implementation Method 1
The steam produced by the steam equipment 93 flows into the frame box 90 via the holes 912 of the support board 91 to proceed a hydration reaction in the slag 95 inside the frame box 90
Implementation Method 2
the steam diffuses upwardly from the bottom of the support board 91 and is likely to be blocked by the pile of the slag 95
Implementation Method 3
Each of the steam tubes connects with a space of the autoclave via the first opening of the steam tube and connects with waste inside the chamber via the second opening of the steam tube

AI summary
Equipment adapted for a waste volume expansion stabilization process has an autoclave (10) and a waste carrying container (20). The waste carrying container (20) is configured for carrying a pile of waste (50), is positioned in the autoclave (10), and has a chamber (22) and a steam conducting unit (30) installed in the chamber (22) and having multiple steam tubes (31). Each steam tube (31) connects with the autoclave (10) via a first opening thereof and connects with the chamber (22) via a second opening thereof. High pressure steam flows into the steam tubes (31) from the first openings and flows into the chamber (22) to be mixed with the pile of the waste (50) via the second opening. The performance of the waste volume expansion stabilization process is improved.
