BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1This is a schematic structural diagram of the cold energy recovery system of the gasification station described in the utility model. DETAILED DESCRIPTION

[0011] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0012] like Figure 1 As shown, the cold energy recovery system of the gasification station includes: a cooling tower 1, a cooling water pool 2, and a storage tank 3 storing liquefied gas. The cooling tower 1 is located above the cooling water pool 2, so that the water in the cooling tower 1 can fall into the cooling water pool 2. A spray pipeline 4 is arranged in the cooling water tower 1. The inlet of the spray pipeline 4 is used to connect with the circulating hot water pipe. The hot water in the circulating hot water pipe is generated by the production needs of the factory. The spray pipeline 4 is used to spray the hot water to cool the water. The cooling water pool 2 is provided with a heat exchanger. The inlet of the heat exchanger 5 passes through the cooling water pool 2 and is connected with the liquid outlet of the storage tank 3. The liquefied gas stored in the storage tank 3 can be liquid nitrogen, liquid argon or liquid oxygen; the outlet of the heat exchanger 5 is used to be connected with the gas main in the factory, so that the gasified gas can be used by the factory. A circulating water pump 6 for extracting cold water from the water pool is also provided on the cooling water pool 2. The outlet of the circulating water pump 6 is used to be connected with the water main in the factory, so that the cold water obtained by cooling can be used by the factory.

[0013] In this embodiment, a cooling fan 7 is provided at the top of the cooling water tower 1. Turning on the cooling fan 7 can make the cooling effect of the water better. A filler 8 that can diffuse water and increase the water heat exchange area is provided at the bottom of the cooling water tower 1. This arrangement can improve the cooling effect of the water. A liquid level gauge 9 for detecting the liquid level is provided on the cooling water pool 2. Due to evaporation, the water in the cooling water pool will gradually decrease, so the liquid level gauge 9 is required to detect the water level. A water replenishment pipe 10 for replenishing water is also provided on the cooling water pool 2. When the water in the cooling water pool is reduced to a certain amount, the cooling water pool is replenished with water through the water replenishment pipe 10.

[0014] The hot water required for factory production enters the spray pipe 4 through the circulating hot water pipe, and is sprayed and cooled by the spray pipe 4. The cooled water will fall into the cooling water pool 2. The water in the cooling water pool 2 will exchange heat with the liquefied gas in the heat exchanger 5, so that the water is greatly cooled, and the liquefied gas can be vaporized.
