Buffer tank and steam generation system

Abstract

The invention discloses a buffer tank and a steam generation system. The buffer tank comprises a tank body, the tank body is provided with a closed cavity, a first port, a second port and a third port, the first port, the second port and the third port communicate with the closed cavity, the first port is used for making the tank body communicate with a liquid inlet pipeline, the second port is used for making the tank body communicate with an evaporator through a first communicating pipeline, the third port is used for making the tank body communicate with a steam return pipeline, a first spray head is arranged in the buffer tank, and the first spray head communicates with the liquid inlet pipeline. The liquid inlet pipeline conveys raw material water into the closed cavity, the first spray head sprays the raw material water into the closed cavity, the steam return pipeline conveys steam flowing back in the evaporator into the closed cavity, so that the steam is mixed with the sprayed raw material water, and the raw material water is heated; and the raw material water is sprayed into the closed cavity by the first spray head, so that the raw material water and the steam are mixed more uniformly, the heating efficiency of the steam on the raw material water is improved, and the temperature of the raw material water entering the evaporator through the first communicating pipeline reaches the standard.

Description

technical field [0001] The invention relates to the technical field of steam preparation, in particular to a buffer tank and a steam generation system. Background technique [0002] The pure steam generator is an important equipment in the pharmaceutical industry. The pure steam generated by it can be used for moist heat sterilization and other processes such as disinfection of equipment and pipelines. According to the film-forming evaporation form of raw water in the tube bundle of the evaporator, it can be divided into falling film pure steam generator and rising film pure steam generator. [0003] The rising film pure steam generator does not need to use a liquid distribution device to form a film, but only needs to ensure that the temperature of the raw water entering the evaporator is close to or greater than the boiling point temperature to obtain better heat transfer efficiency. However, most of the current rising film pure steam generators have the problem of insuff...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a buffer tank and a steam generation system; the buffer tank can heat the raw water entering the evaporator, so that the temperature of the raw water entering the evaporator is close to or greater than the boiling point, ensuring that the water entering the evaporator Heat transfer efficiency, to ensure the evaporation efficiency of raw water in the evaporator; the steam generation system includes the aforementioned buffer tank, which solves the problem of insufficient temperature of raw water entering the evaporator, and makes the heat transfer efficiency of the evaporator of the steam generation system higher
