Embodiment approach 1

[0042] For example figure 1 , figure 2 As shown, the multi-stage liquid storage type condensing evaporator 1 according to one embodiment of the present invention is composed of four evaporation areas connected in the vertical direction (in order from the first evaporation area 9 to the fourth evaporation area 15) . Here, the evaporation region refers to a region where the liquid is evaporated by exchanging heat between the gas and the liquid. Such as image 3 As shown, the multi-stage liquid storage condensing evaporator 1 has: a heat exchanger core 5, which is constructed by a heat exchange part 3 and a liquid communication part 4, and the liquid communication part 4 is composed of two The first liquid communication passage 35 to the third liquid communication passage 39 on the side are formed; and the multistage liquid reservoir 7 is formed on both sides of the heat exchanger core 5 in the width direction.

[0043] Next, each structure will be described in detail. In t...

Embodiment approach 2

[0087] In the above description, the liquid storage part 7 has the function of storing liquid oxygen and the function of collecting oxygen as an example, but the liquid storage part 7 does not necessarily have the function of collecting oxygen. Figure 11 and Figure 12 An example of such a reservoir is shown. Figure 11 show figure 1 A modified example of the multi-stage liquid storage condensing evaporator shown, Figure 12 show Figure 10 A modified example of the reservoir shown, Figure 11 and Figure 12 Both are open-type multi-stage liquid-storage condensing evaporators 60 in which the upper part of the liquid storage part 7 is opened.

[0088] exist Figure 11 and Figure 12 in, right with figure 1 and Figure 10 Identical structures use the same reference numerals.

[0089] Such as Figure 13 As shown, in the case of an open multi-stage liquid storage condensing evaporator 60, it is placed in a gas collection container 61 covering the entire multi-stage liq...

Abstract

A multistage liquid-reservoir-type condensation evaporator according to the present invention comprises: a heat exchanger core composed of a heat exchange part formed by stacking a condensation passage and an evaporation passage adjacently, and a liquid communication part formed by a liquid communication passage on at least one side of the heat exchange part in the stacking height direction; and one or more stages of liquid reservoir parts on the side surface on at least one side of the heat exchanger core in the width direction thereof.

Description

technical field [0001] The invention relates to a liquid storage condensing evaporator, which uses heat by introducing the liquid in the liquid storage arranged on at least two evaporation areas into the evaporation channel and exchanging heat with the gas flowing through the condensation flow channel. The siphon acts to evaporate the liquid and condense the gas. [0002] This application claims priority based on Japanese Patent Application No. 2014-169825 for which it applied to Japan on August 22, 2014, and uses the content here. Background technique [0003] The liquid storage condensing evaporator makes the liquefied oxygen from the bottom of the low-pressure distillation column (hereinafter referred to as "low-pressure column") of the air liquefaction separation device constructed by the double rectification tower and the liquefied oxygen from the high-pressure distillation column (hereinafter referred to as "low-pressure column") The nitrogen at the top of the high pr...
