Example Embodiment

[0018] Example

[0019] This method is applied to the vaporization of chlorine in the phosphorus trichloride production process. The vaporization amount of chlorine in the process is 6.46t / h, the vaporization pressure is controlled at 0.2Mp, the vaporization temperature is -6℃~-7℃, and the chilled brine is used as the refrigerant, the cooling power can reach 490KW. Through vaporization, low-temperature brine at -5°C to 0°C can be prepared for cooling other links in the production process. Compared with the previous liquid chlorine vaporization, this method not only does not require warm water or steam, but also effectively utilizes the vaporization cold energy. Killing two birds with one stone, the energy saving effect is remarkable.

Abstract

The invention relates to a device for recovering liquid gas gasification cold. Most industrial gases are stored in the form of liquid before use, the liquid gas is required to be gasified during use, the gasification process of the liquid gas is an endothermic process and a great quantity of cold is produced. The traditional method is to use hot water or high-temperature steam to neutralize the cold. The invention aims at gasifying the liquid gas at low temperature and recovering the cold by using proper cold carriers. The device for recovering liquid gas gasification cold not only can realize the normal gasification of the liquid gas, but also does not need the traditional heat source and can effectively recover the cold. The energy saving effect is remarkable and the significance to popularization is very great.

Description

technical field [0001] The invention is an invention patent, which is used for recovering the cooling capacity of vaporization of liquid gas. This process can effectively recover the cold energy produced by the vaporization of various industrial gases. Background technique [0002] In order to facilitate the transportation and storage of gases in industry, many industrial gases are stored in liquid form before use, so they need to be vaporized before use. Since the vaporization process is an endothermic process, a large amount of heat must be consumed to ensure the vaporization of the gas. At present, most industrial vaporization uses hot water or high-temperature steam to absorb the cooling energy of vaporization under medium and high pressure to achieve the purpose of vaporization. This method needs to consume a large amount of energy to obtain hot water or high-temperature steam, and the operating cost is high, and the cold energy is lost to steam or hot water, which is...
