Description

一至二段变换炉
技术领域
本发明涉及一种变换炉，尤其涉及一种一至二段变换炉。
背景技术
变换炉是内蒙古港原电石化工40万吨/年电石项目改造工程LNG装置中中的关键设备。该设备设计压力4.1MPa，设计温度475℃，主体材料为14Cr1MoR和14Cr1Mo锻件。
在煤化工行业中，一、二段变换炉传统的结构每台都是独立的，两台设备由管道串联在一起，这样的结构优点是设备总高度低，配管和设置平台容易，再者承受风载小，相对安全些。缺点是占地面积大，消耗钢材多。
发明内容
本发明的目的是提供一种结构简单、费用低、占地面积少的一至二段变换炉。
本发明的目的是通过以下技术方案实现的：
本发明的一至二段变换炉，包括上下叠在一起两段变换炉，两段变换炉共用一个外壳体，壳体内通过设置中间封头分成上下两个独立的容器。
由上述本发明提供的技术方案可以看出，本发明实施例提供的一至二段变换炉，其特征在于，由于两段变换炉共用一个外壳体，壳体内通过设置中间封头分成上下两个独立的容器，简化了结构、节约了材料和占地面积。
附图说明
图1为现有技术中单段变换炉的结构示意图。
图2为本发明实施例提供的一至二段变换炉的结构示意图。
图中：1、一段变换炉，2、中间封头，3、二段变换炉。
具体实施方式
下面将对本发明实施例作进一步地详细描述。
本发明的一至二段变换炉，其较佳的具体实施方式是：
包括上下叠在一起两段变换炉，两段变换炉共用一个外壳体，壳体内通过设置中间封头分成上下两个独立的容器。
所述中间封头为球缺状的隔板。
所述球缺状的隔板的厚度优选为26mm。
本发明的一至二段变换炉，把两台设备叠在一起，共用一个外壳体，然后设置中间封头，把整台设备分成两个独立的容器。
与以前技术相比，本发明的优点在于：
从技术方面来看，这种改进是可行的，技术方案是经过理论验证的。
从经济方面来看：
节省材料费用：
节约了两个直径Φ3500mm，厚度40mm的半球形封头，改型后只采用一个厚度26mm的球缺做为分隔容积的隔板。这部分节省的材料费和模具费大约在16万元人民币。
节约了一个Φ3500mm，厚度20mm，高度5000mm的裙座。这部分节省材料费用大约在4万元人民币。
节约了一套地脚螺栓及紧固件。以前单台设备有20个M30的地脚螺栓及其相配的紧固件，现在节约下来的紧固件的成品费用约2万元人民币。
节约连接管道费用约2万元人民币。
加工费用：从加工和人工工时来看，可节省费用约3万元人民币。
节省占地面积。
综上所述，本发明方案确定后，方案评审得到了专家和业主的认可，现在一至二段变换炉设计图样已经完成，制造厂家已经开始制造加工。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书的保护范围为准。
