Description

Technical Field

[0001] The utility model relates to the technical field of pure steam generators, and particularly relates to a shell-and-tube pure steam generator. Background Art

[0002] Steam, also known as "water vapor", is classified into saturated steam and superheated steam according to pressure and temperature. The main uses of steam are heating, humidifying; it can also generate power and be used as machine drive, etc. A pure steam generator is a device that uses raw steam with relatively low purity to produce pure steam with relatively high purity, and is widely used in the sterilization and disinfection of medical and health, biopharmaceutical industry, food industry and related utensils, effectively preventing the recontamination of impurities such as heavy metals.

[0003] The existing published patent number is (CN219328068U). The utility model provides a pure steam generator, which belongs to the technical field of pure steam generators, including: an evaporator, which is provided with a raw steam inlet, a first steam condensate outlet, a secondary raw water inlet, a concentrated water outlet, a shell side and a tube side; a vapor-liquid pre-separation device, which is provided with a secondary steam outlet; a preheater, which is provided with a first steam condensate inlet, a second steam condensate outlet, a secondary raw water outlet and a raw water inlet; a separator, which is connected to the preheater and forms a second steam chamber, and the separator is provided with a secondary steam inlet, a pure steam outlet and a condensate outlet. The beneficial effect of the utility model is that the separator is connected to the preheater, and the preheater can well utilize the high-temperature steam condensate separated by the separator to preheat the raw water; at the same time, the vapor-liquid pre-separation device is connected to the evaporator, and the separated micro-droplets can be evaporated again, reducing the discharge of steam condensate, improving the heat exchange efficiency and reducing the steam consumption. However, in the actual use process, the steam generation process of this device is short, which affects the steam effect, and the stability of this device is poor.
