It utilizes, is not only the significant wastage to secondary resource and the energy, but also very big pollution, therefore, steel slag can be caused to environment
Problem of complex utilization gradually cause the attention of China steel industry colleague.
The molten steel slag temperature being discharged in steelmaking process contains heat about 2000MJ/t, is equivalent to up to 1450~1650 DEG C
61kg standard coal belongs to high-quality residual heat resources, great value of exploiting and utilizing.However, the country is about steel slag heat recovery at present
The research of aspect is seldom, and the heat recovery technology of steel slag is also immature, and existing treatment process has respective advantage and disadvantage.In the energy
In the epoch that are nervous, advocating comprehensive energy, how to realize the high efficiente callback of steel slag waste heat, is that Iron and Steel Enterprises in China is paid high attention to
One of research topic, while being also a global advanced subject and technical problem.Therefore, more than Study on Acceleration exploitation steel slag
Recuperation of heat is a current steel and iron industry important subject urgently to be resolved using technology.
Summary of the invention
Present invention aim to provide a kind of stewing processing waste-heat recovery device of steel slag pit heat, without using steam
Turbine generates electricity, and structure is simple, and temperature applicable range is wide, the interruption production method suitable for slag processing.
To achieve the above object, the stewing processing waste-heat recovery device of a kind of steel slag pit heat designed by the present invention, including heat
Stewing pond and the stewing lid of heat, the heat is stewing to be covered equipped with Stirling engine, and the cold chamber setting of the Stirling engine is in the stewing lid of heat
Outside, the hot chamber setting of the Stirling engine is on the inside of the stewing lid of heat.
Further, the heat is stewing covers equipped with cold water pipe, and the cold water pipe flows through the cold chamber of Stirling engine.
Further, described cold intracavitary equipped with thermally conductive sheet, the cold water pipe flows through thermally conductive sheet.
Further, metallic network of pipelines is provided with outside the hot chamber, the hot chamber is arranged in metallic network of pipelines.
As preference, the Stirling engine is equipped with more, and the more Stirling engines are evenly distributed on heat
It is stewing to cover.
As preference, the cold water pipe is divided into multiple Zhi Liuguan, and each Zhi Liuguan flows through each Stirling and starts
The thermally conductive sheet of machine.
As preference, the metallic network of pipelines is connected to the hot chamber of each Stirling engine.
The present invention has the advantages that effective recycling steel slag thermal energy, comes again it is not necessary that steel slag thermal energy is changed into water vapour
It is generated electricity using water vapour, reduces energy conversion loss；System flow is short, and equipment is simple, and maintenance is small, and failure rate is small, reliability
It is high；Temperature applicable range is wide；Multiple spot recycles thermal energy, and the rate of recovery is high.
Detailed description of the invention
Fig. 1 is use state diagram of the invention；
Wherein: the stewing pond 1 of heat, heat stewing lid 2, Stirling engine 3 (wherein: cold chamber 3.1, hot chamber 3.2), 4 (its of cold water pipe
In: Zhi Liuguan 4.1), thermally conductive sheet 5, metallic network of pipelines 6, spray head 7.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments:
As shown in Figure 1, the stewing processing waste-heat recovery device of steel slag pit heat of the present invention includes the stewing pond 1 of heat and the stewing lid 2 of heat, heat is stewing
Lid 2 is equipped with Stirling engine 3, and the setting of cold chamber 3.1 of Stirling engine 3 is in stewing 2 outside of lid of heat, Stirling engine 3
The setting of hot chamber 3.2 in stewing 2 inside of lid of heat.
Further, the stewing lid 2 of heat is equipped with cold water pipe 4, and cold water pipe 4 flows through the cold chamber 3.1 of Stirling engine 3.Cold chamber
Thermally conductive sheet 5 is equipped in 3.1, cold water pipe 4 flows through thermally conductive sheet 5.Metallic network of pipelines 6 is provided with outside hot chamber 3.2, hot chamber 3.2 is arranged in gold
Belong in pipe network 6.
Stirling engine 3 is equipped with more, and more Stirling engines 3 are evenly distributed on the stewing lid 2 of heat.Cold water pipe 4 divides
The thermally conductive sheet 5 of each Stirling engine 3 is flowed through for multiple Zhi Liuguan 4.1, each Zhi Liuguan 4.1.Metallic network of pipelines 6 is connected to each
The hot chamber 3.2 of Stirling engine 3.
In actual use:
More Stirling engines 3 are mounted on the stewing lid 2 of heat, when external cooling water is stewing by cold water pipe 4 and heat
When the spray head 7 of 2 lower part of lid is sprayed water, the cold chamber 3.1 of more Stirling engines 3 must be flowed through, and by the thermally conductive sheet in cold chamber 3.1
