Description

深冷分离装置冷箱
技术领域
本实用新型涉及一种深冷分离装置，尤其涉及一种撬装型式的深冷分离装置冷箱。
背景技术
深冷分离法就是利用需要加工处理的原料气所含各组分沸点的差别，在低于-100℃温度下进行热、质交换，分离回收其中某些组分的过程。
深冷分离装置冷箱广泛地应用于冶金、石油化工、采矿、电子等行业，如空气分离及液化装置冷箱、乙烯装置冷箱、天然气液化装置冷箱、焦炉气提纯装置冷箱。深冷分离装置的冷箱内布置有多台不同结构形式的设备、连接设备的管道，以及进行控制和操作的阀门、仪表等。
深冷分离装置冷箱内的设备、管道选用的材料，常用的有：不锈钢、铜合金、铝合金。共同的特点是能够在-196℃温度下，材料不会发生低温冷脆。而冷箱内设备及管道在常温下制造、安装，≤-100℃的低温下使用，且在整个装置运行过程中，冷箱壳体表面温度接近环境温度。所以，合理的结构设计和优化布置能使冷箱的截面尺寸更合理，降低因温差变化产生的二次应力对设备、管道的破坏，减少装置冷量损失，保证深冷分离装置冷箱的安全运行。
发明内容
本实用新型的目的是克服现有的冷箱结构设计的不足，提供了一种优化了撬装冷箱结构，降低设备投资成本及撬装冷箱的运输成本的深冷分离装置冷箱。
为了解决上述技术问题，本实用新型通过下述技术方案得以解决：
深冷分离装置冷箱，包括换热器、过冷器、蒸发器、冷凝器、分离器                                                
Figure 655892DEST_PATH_IMAGE001
、与冷凝器相连的分离器及精馏塔，换热器包括换热器上段和换热器下段，换热器上段、换热器下段、精馏塔依次通过管道连接，所述分离器固定在换热器下段上，所述精馏塔与蒸发器连接。上述设计既节约了冷箱空间，又比在冷箱壁设置支撑的方法降低了冷量损失。
作为优选，所述的换热器上段的中部与冷凝器共同固定在支撑架
Figure 732935DEST_PATH_IMAGE001
上，换热器上段的底部与精馏塔共同固定在支撑架
Figure 162779DEST_PATH_IMAGE002
上。
作为优选，深冷分离装置冷箱还包括设备支座和设置在设备支座上的支撑梁。
作为优选，所述的设备支座和支撑梁之间设置有隔冷材料层。
本实用新型冷箱内的主要设备依据装置工艺过程进行优先排列、定位，再根据设备的工作温度区间进行附属设备的定位。利用主要设备的支撑元件或在主要设备上设置附属设备的支撑件，减少了在冷箱壁设置支撑件。通过合理选择支撑元件材料，防止出现“冷桥”，减少冷量的传递。
本实用新型各设备之间的连接管道，均围绕设备布置。经计算确定管子间的合理间距；依据管内介质的相态或温度，将管子进行分区布置；进行管子及设备低温工况时的收缩量（与常温安装比较）计算，确定管道的合理走向布置及支撑件的合适结构，节约内部空间，减小撬装冷箱的外形尺寸。
本实用新型由于采用了以上技术方案，具有显著的技术效果：
本实用新型优化了撬装冷箱结构，降低设备投资成本及撬装冷箱的运输成本，具有较高的实用性。
附图说明
图1是本实用新型撬装冷箱结构示意图。
图2是图1的左视图。
具体实施方式
下面结合附图1至附图2与实施例对本实用新型作进一步详细描述：
实施例1
深冷分离装置冷箱，包括换热器、过冷器1、蒸发器2、冷凝器3、分离器4、与冷凝器3相连的分离器
Figure 741845DEST_PATH_IMAGE002
5及精馏塔6，换热器包括换热器上段11和换热器下段12，换热器上段11、换热器下段12、精馏塔6依次通过管道连接，所述分离器4固定在换热器下段12上，比在冷箱壁设置支撑的方法降低了冷量损失。所述精馏塔6与蒸发器2连接。换热器上段11的中部与冷凝器3共同固定在支撑架
Figure 720482DEST_PATH_IMAGE001
7上，换热器上段11的底部与精馏塔6共同固定在支撑架8上。
本实用新型还包括设备支座10和设置在设备支座10上的支撑梁9，设备支座10和支撑梁9之间设置有隔冷材料层。同时在支撑梁9中填充导热系数低的填充材料，降低因梁中空气流动而增加的冷量损失，防止出现“冷桥”，减少冷量通过支撑件向冷箱壁传递。
原料气先后经过换热器和过冷器1，换热后进入精馏塔6进行分离，返流产品气经过冷器1、换热器回收冷量后送出冷箱，蒸发器2、冷凝器3分别提供过冷器1所需的蒸发和冷凝热负荷。
对于圆形设备的支撑架，设置了挡块，防止因运输冷箱时设备的移动而损害与设备连接的管道。在冷箱内的设备与支撑架之间设置了非金属垫片，减少了设备表面与支撑间的摩擦损伤和保证设备自由伸缩而降低摩擦系数。冷箱壳体和设备之间装填保温材料，阻止设备冷量向环境传递，保证了深冷分离装置冷箱内低温设备的在设计工况运行。
上述设计使得冷箱的布置结构更合理，内部空间设计紧凑。
总之，以上所述仅为本实用新型的较佳实施例，凡依本实用新型申请专利范围所作的均等变化与修饰，皆应属本实用新型专利的涵盖范围。
