Embodiment approach 1

[0268] Figure 16 It is an explanatory drawing explaining the structure of the manufacturing apparatus of the clathrate hydrate slurry which concerns on one Embodiment of this invention.

[0269] The clathrate hydrate slurry manufacturing apparatus according to this embodiment includes: a heat exchanger 1 for exchanging heat between a raw material solution (an aqueous solution of a guest compound that forms a hydrate) or a raw material slurry and a refrigerant; a refrigerant supply device 21, which supplies refrigerant to the heat exchanger 1; the heat storage tank 5, which stores the raw material solution or raw material slurry and the generated hydrate slurry; the input side flow path 8, one end of which communicates with the heat storage tank 5, and the other end It communicates with the input side of the heat exchanger 1; the output side flow path 9 communicates with the output side of the heat exchanger 1 at one end and communicates with the heat storage tank 5 at the oth...

Embodiment 1

[0326] [Heat storage air conditioning system 1]

[0327] In the heat storage air conditioning system 1 according to Embodiment 1, the refrigerator for slurry production is operated at night to store heat, and the stored heat is released during the day to perform cooling operation. When the cooling load is high during the day, the slurry production The refrigerator operates to store heat while performing cooling and cooling operation. It has the feature that even when the cooling load is high during the daytime, it can be handled by one refrigerator for slurry production.

[0328] Figure 18 It is an explanatory drawing of the equipment structure of Example 1, and shows the equipment structure when it is applied to the building whose maximum cooling load corresponds to 400RT.

[0329] The heat storage air-conditioning system 1 involved in Embodiment 1 has: a refrigerator 81 for slurry production, which produces hydrate slurry; a heat storage pump 82, which is installed on the...

Embodiment 2

[0345] [Heat storage air conditioning system 2]

[0346] The heat-storage air-conditioning system 2 according to the second embodiment is based on storing heat by operating the freezer for slurry production at night, and performing cooling operation in which heat is released and stored during the day, and can be used when the cooling load is high during the day. It is supplemented by cold water produced by other chillers.

[0347] Figure 19 is an explanatory diagram of the device structure of the present embodiment 2, and Figure 18 The same parts are denoted by the same reference numerals. Such as Figure 19 Shown, in this embodiment 2, in Figure 18 In addition to the structure shown, the chiller 91 for cold water which produces 7 degreeC cold water, and the primary pump 92 for cold water which send cold water from the chiller 91 for cold water are added.

[0348] The heat storage operation at night and the cooling operation using heat storage during the day were perfo...

Abstract

A technique by which a clathrate hydrate slurry can be stably produced over long while maintaining a merit that a clathrate hydrate adherent to the heat exchange surface of a heat exchanger has the effect of accelerating the fresh formation of a clathrate hydrate. It is a process for producing a clathrate hydrate slurry which comprises a step in which either an aqueous solution of a guest compound for a clathrate hydrate or a slurry obtained by dispersing or suspending the clathrate hydrate in the aqueous solution or water is caused to flow in a heat exchanger tube to yield the clathrate hydrate in the aqueous solution or the slurry through heat exchange with a refrigerant surrounding the outer periphery of the heat exchanger tube. The process is characterized in that the amount of the clathrate hydrate adhering to the inner wall surface of the heat exchanger tube in the course of heat exchange with the refrigerant is inhibited from increasing by means of the force of flow of the aqueous solution or slurry running in the heat exchanger tube.

Description

technical field [0001] The present invention relates to the manufacturing technology of clathrate hydrate slurry using heat transfer tube as heat exchanger, in particular, it relates to a manufacturing method of clathrate hydrate slurry, a device for realizing the manufacturing method and an operation method of the device, The production method of the clathrate hydrate slurry has a step of flowing an aqueous solution of the guest compound of the clathrate hydrate or a slurry obtained by dispersing or suspending the clathrate hydrate in the aqueous solution or water into the inside of the heat transfer tube. A clathrate hydrate is formed in the aforementioned aqueous solution or the aforementioned liquid slurry through heat exchange with the refrigerant located at the periphery of the heat transfer tube. [0002] In the present invention, definitions or explanations of terms shown below are as follows. [0003] (1) "Cathrate hydrate" includes quasi-clathrate hydrate. Hereinaf...
