An air heat source type low temperature liquefied gas vaporizer (hereinafter simply referred to as a liquefied gas vaporizer) that uses the atmosphere as a heat source,
This is an extremely important device that vaporizes liquefied natural gas, etc., but the conventional device is shown in Figure 1.
As shown in Fig. 2, a plurality of (n) finch tubes 1 to 1 are arranged vertically so that their centers are on the same plane, and when they are adjacent to each other on the left and right, their upper and lower ends are alternately connected to connecting tubes. Generally, a plurality of rows (m rows) of rows connected in series by 4 are arranged in parallel, and this is used as a heat exchange section, and a header 5 having nozzles 9 and 10 on connecting pipes at both ends, respectively.
and 6 are connected. The low-temperature liquefied gas is supplied from the inlet nozzle 9 and is evenly distributed from the header 5 to the plurality of rows of heat exchange sections 1 11 to 1 n1 .
The fin tube has a cross section as shown in FIG. 3, and is composed of fins 2, 2' and an inner tube 3. Finch Ube 1 for low temperature liquefied gas
While passing through the fins 2 and the inner tube 3, heat is removed from the atmosphere and vaporized. Therefore,
The heat exchange section near the inlet is in a state of gas-liquid mixture,
At the exit, it becomes superheated vaporized gas.

A part of the heavy components of C 4 H 10 or more in the gas accumulates in liquid form in the finch tube 1 or the connecting pipe 4 and blocks them.
It had the disadvantage of obstructing gas flow and reducing heat transfer performance. Further, even if the pipe did not become clogged, the vaporized gas delivered contained less heavy components, and the composition of the vaporized gas varied depending on the load variation. If the components of vaporized gas differ, the calorific value of the gas will change, and in cases where the calorific value must be constant at all times, such as with city gas, it is extremely inconvenient that the calorific value must be adjusted according to load fluctuations. There was an economic problem.

が出来る。 4 and 5, multi-component liquefied gas (for example, liquefied natural gas) containing heavy components supplied from the inlet nozzle 9 passes through the header 5 and passes through a plurality of rows of finch tubes 1 11 to 1 n1 (fifth (Fig. 4), but passes through the inner pipe 3 (Fig. 3) of the first-stage finch tube (1 11 in Fig. 4) and sequentially flows to the lower-stage finch tube. During this time Finn 2
The heat obtained from passing through the outer surface of the evaporates as it heats up. If the load is small, it may all vaporize in the upper stage up to the gas-liquid separator 11;
In normal cases, only the low-boiling components are vaporized, and the heavy mass flows into the gas-liquid separator 11 via the header 7 in a gas-liquid mixed state without being vaporized. Here, the unevaporated heavy mass and the vaporized gas are separated, and the vaporized gas is sent to the gas-liquid separator 11.
The air is sent from the inner tube 12 that opens into the gas phase of the air to the header 8 via the tube 16, and is further distributed evenly to the lower finch tubes 11(o-1) (there are multiple rows of these), where it is heated by the outside air. , reaches the lowest stage finch tube 1 1o , passes through the outlet header 6, and connects to the pipe 18.
and reaches the gas-liquid contactor 14. On the other hand, the unevaporated heavy mass separated by the gas-liquid separator 11 is guided from the liquid phase part of the gas-liquid separator 11 to the gas-liquid contactor 14 through the pipe 17 with the flow rate adjusted by the flow rate regulator 13. , where the superheated vaporized gas from the tube 18 is vaporized by direct contact. The flow rate of the unevaporated heavy components flowing out from the liquid phase portion of the gas-liquid separator 11 is controlled by the flow rate adjustment device 13 so that the composition of the final outlet gas of this device is equal to the composition of the liquefied gas initially supplied. Ru. This control mechanism is performed, for example, by continuously automatically analyzing the outlet gas composition and the supplied liquefied gas composition and sending a control signal to the flow rate regulator 13. Note that if the gas-liquid separator 11 is not provided and the heat exchange section is not divided into an upper stage and a lower stage but is configured as an integral part, the heavy components tend to flow in a layered manner under the finch tube, reducing heat transfer efficiency and preventing complete vaporization. There is a risk that the heavy components may be sent out from the vaporizer without being evaporated. According to this device, it is possible to efficiently exchange heat and vaporize the unevaporated heavy components using the gas-liquid contactor 14 that atomizes them.
このようにして、本発明の装置においては常に
供給液化ガスの成分と同成分の気化ガスを送出す
ることができるのである。 In this manner, the apparatus of the present invention can always deliver vaporized gas having the same components as the supplied liquefied gas.

になるように上段部のフインチユーブを傾斜させ
て設けるのも好ましい方法である。 In addition, when the load is low, unevaporated heavy components accumulate in the upper finch tube or the connecting pipe 4, and as the load increases rapidly, low-temperature liquefied gas flows in, and when they come into contact, they solidify or become highly viscous. If there is a risk of blockage of the finch tube due to
As shown in the figure, it is also a preferable method to provide the upper finch tube at an angle so that the flow direction of the liquefied gas is slightly downward.

If a gas-liquid separator is not provided and the heat exchange section is not divided into an upper stage and a lower stage, but is constructed as an integral part, the heavy components tend to flow in a layered manner under the finch tube, resulting in poor heat transfer and not being completely vaporized. In contrast, in the present invention, the heat exchange section is divided into an upper stage and a lower stage, so that the heavy components may be sent out from the vaporizer without being evaporated.
Since the gas-liquid separator 11 is provided in between to take out the heavy components from the middle, the heavy components do not accumulate in the connecting pipe and can be efficiently vaporized.

The flow rate is adjusted by the gas-liquid contactor 1 through the pipe 17.
4, where it directly contacts and vaporizes the superheated vaporized gas from the pipe 18, continuously automatically analyzes the outlet gas composition and the supplied liquefied gas composition, and sends a control signal to the flow rate adjustment mechanism 13. This allows the composition of the final outlet gas of the device to be controlled to be equal to the composition of the initially supplied liquefied gas.
