を低温ガスの冷熱により淡水化するものてある。DETAILED DESCRIPTION OF THE INVENTION The present invention uses seawater to heat low-temperature gas, and at the same time desalinates this seawater using the cold heat of the low-temperature gas.
例えばLNGの再ガス化時等の冷熱は利用することなく
すてられているのが現状である。For example, the current situation is that cold energy generated during regasification of LNG is not used and is wasted.

図の系統図により説明する。The present invention performs heating for this gasification using seawater,
On the other hand, this seawater is produced by crystallizing ice using the cold heat of LNG, which is then separated and melted to desalinate the seawater. In other words, it is a launching device that utilizes the cold energy of low-temperature gas. According to this system, there is no need for refrigeration cycle forming equipment such as refrigerant, compressor, condenser, etc. as in conventional refrigeration seawater desalination equipment, and it can be constructed mainly from stationary equipment, resulting in low cost and easy operation and maintenance. It can be used as a device. The device of the present invention is the first
This will be explained using the system diagram shown in the figure.
1は直接接触式の海水・ガス熱交換器でその内部では上

より結晶缶2に送られる。Near the bottom of the vessel, low-temperature gas is supplied from a pipe 17, where the seawater and low-temperature gas come into direct contact in a countercurrent manner to exchange heat. There is a stirrer 6 at the bottom of the vessel, which thoroughly mixes the ice crystal nuclei generated by the supercooling of the seawater through the heat exchange with the seawater. The heated gas is sent out through pipe 18. Seawater containing ice crystals formed in the heat exchanger 1 is sent to the crystallizer 2 via a pipe 19.

リーポンプ8により洗浄塔3にその下部より送りこむ。It plays the role of mixer 7 or preventing the generation of ice blocks. On the other hand, the low temperature gas dissolved in the seawater is extracted by the compressor 5 and returned to the heat exchanger 1. In this way, in the crystallization can 2, crystallized ice and concentrated seawater, ie, brine, are mixed and exist in the form of a slurry. This slurry is sent to the washing tower 3 from the lower part by a slurry pump 8.
なおポンプ9で結晶缶2の底部のブラインを熱交換器1
との間に循環させ、熱交換器1における氷の結晶核発生
を助ける。The pump 9 pumps the brine at the bottom of the crystallizer 2 into the heat exchanger 1.
This helps generate ice crystal nuclei in the heat exchanger 1.
洗浄塔3て氷結晶は浮上して塔の上部に氷層をなす。The ice crystals float to the surface of the washing tower 3 and form an ice layer on the top of the tower.

融解槽である。A washer 12 for sprinkling fresh water to wash this ice layer is located at the top of the tower, and there is also an ice scraper 10 here for scraping off the top of the ice layer. The ice scraped here is dropped into a melting tank 4 surrounding the washing tower 3. On the other hand, the brine is sent out of the column 3 by a pipe 13 through a screen 3a provided on the column wall at the middle of the height of the washing column 3.
In this way, ice corresponding to the amount of ice fed into the washing tower 3 is scraped off, brine is sent out, and the separation action proceeds continuously. The pipe 14 is for returning circulating brine from the washing tower 3 to the crystallization vessel 2 in order to keep the slurry concentration constant. 4 is a melting tank forming the outer periphery of the cleaning tower 3.

る処であるが、つぎのような特徴をもつ。The ice scraped here as described above is melted by the heating pipe 15 using sea water, and is sent out of the tank by the fresh water pump 11. In this figure, a part of the fresh water sent out is used for washing the ice in the washing tower 3 as described above.
As can be understood from the above, the present invention has the following features, although some parts of the present invention have already been completed.
1多量の海水を使用して低温ガスを間接的に加熱してい

量が大巾に減少出来る。1.Compared to the conventional method of indirectly heating low-temperature gas using a large amount of seawater, this invention uses a direct catalytic method to heat the gas, and also utilizes the freezing latent heat of the seawater, which significantly reduces the amount of seawater used. can be reduced to
2冷媒(ブタン又はフレオン等)液を海水中に吹き込み
その潜熱を利用して海水を冷却(晶析を含む)させてい
た従来方法は冷凍サイクルを形成する為に圧縮機・凝縮

機器は不要と成りプロセスが簡単に成る。2) The conventional method of injecting liquid refrigerant (butane or freon, etc.) into seawater and utilizing its latent heat to cool the seawater (including crystallization) is to refrigerate compressors, condensers, etc. to form a refrigeration cycle. However, according to the present invention, there is no need for such equipment and the process is simplified.
又低温ガスが高圧ガス取締法にかからないもので得るこ
とが出来るならば淡水化プロセスは大気開放式とする事
が出来るので建設費等大巾に低減される。Furthermore, if low-temperature gas can be obtained that is not subject to the High Pressure Gas Control Law, the desalination process can be open to the atmosphere, which greatly reduces construction costs.
