    • A heat exchanger for an easily polymerizing substance-containing gas provided with a shell possessed of a heat-exchanging gas inlet and a heat-exchanging gas outlet and a heat-exchanging part adapted to circulate fluid introduced from outside the shell between the gas inlet and said gas outlet, which heat exchanger is characterized by being provided with a gas distributing plate between the gas inlet and the heat-exchanging part. The heat exchanger is characterized by the gas distributing plate having a cross-sectional area in the range of 1.0-10.0 times the cross-section of the gas inlet. When an easily polymerizing substance-containing gas contacts a structure, the gas is condensed on the contact surface of the structure and suffered to generate a polymer. According to the heat exchanger of this invention, by uniformly distributing a gas in the heat-exchanging part, it is made possible to attain uniform distribution of heat, depress the possible condensation of the gas, and prevent the easily polymerizing substance from succumbing to polymerization.
    • 一种用于容易聚合的含物质气体的热交换器,其具有壳体,该壳体具有热交换气体入口和热交换气体出口,以及热交换部分,其适于使从壳体外部引入的流体在气体入口和 所述气体出口,其特征在于在气体入口和热交换部分之间设置有气体分配板。 热交换器的特征在于气体分布板的横截面积在气体入口横截面的1.0-10.0倍的范围内。 当容易聚合的物质的气体接触结构时,气体在结构的接触表面上被冷凝,并产生聚合物。 根据本发明的热交换器,通过在热交换部中均匀分布气体,可以获得均匀的热分布,抑制气体的可能的冷凝,并且防止容易聚合的物质屈服于聚合 。

    • A shell-and-tube type heat exchanger of the smallest possible length necessary for heat exchange is disclosed which is capable of obtaining uniform distribution of flow of a shell side fluid and substantially eliminating the structural restriction imposed on the shell side. This shell-and-tube type heat exchanger is provided with one annular conduit furnished with not less than two partitions concurrently serving as an expansion joint for introducing and discharging a shell side fluid and allowing the flow path for said shell side fluid to be separated into an introducing part and a discharging part and which comprises a place having no array of heat-transfer tubes in the flow path for said shell side fluid. It prevents the equipment from necessitating an unnecessary enlargement due to the structural restriction on the shell side and enables the shell side fluid to produce a uniform flow.
    • 公开了一种能够获得壳侧流体的均匀流动分布并且基本上消除了对壳体侧面的结构限制的壳体管式热交换器,其具有热交换所需的尽可能小的长度。 这种管壳型热交换器设置有一个环形导管,其具有不少于两个隔板,同时用作用于引入和排出壳侧流体的膨胀接头,并且允许将所述壳侧流体的流动路径分离成 引入部分和排出部分,并且包括在用于所述壳侧流体的流动路径中不具有热传递管阵列的位置。 它防止了由于壳体侧面的结构限制而使设备不必要地增大,并且使得壳侧流体能够产生均匀的流动。
