Problems solved by technology

This type of equipment has certain limitations in use. When the cold source medium is low-temperature medium such as LNG, liquid nitrogen, and liquid oxygen, there are certain requirements for the taste of the heat source medium. If water is used for heating, the water temperature is required to be at 20°C Above, in order to prevent the water from freezing during the heating process, which will affect the safe and stable operation of the equipment

Abstract

The invention relates to an intermediate medium type gasifier. The intermediate medium type gasifier comprises a cylindrical shell, a heat source heat exchange tube bundle arranged on the lower half part in the cylindrical shell, a cold source heat exchange tube bundle arranged on the upper half part in the cylindrical shell, a heat source tube plate encapsulating one end of the cylindrical shell, a cold source tube plate encapsulating the other end of the cylindrical shell, a heat source tube box arranged on the outer side surface of the heat source tube plate, and a cold source tube box arranged on the outer side surface of the cold source tube plate; the shell, the cold source tube plate and the heat source tube plate jointly form an accommodating space of an intermediate medium; a cold source inlet and a cold source outlet are formed in the cold source tube box; and a heat source inlet and a heat source outlet are formed in the heat source tub box. The intermediate medium type gasifier is suitable for the conditions that the cold source medium has low working temperature as well as the heat source medium has low temperature grade and is liable to freeze during heating. The equipment is high in heat exchange efficiency and high in stability.

Description

technical field [0001] The invention relates to an intermediate medium gasifier and a low-temperature medium gasification method utilizing the same. Background technique [0002] Low-temperature media such as LNG need to be gasified before they can be used. Therefore, a gasification heat exchange device is needed to heat it. At present, the commonly used equipment is that the heat source medium directly heats the cold source medium through a metal partition. This type of equipment has certain limitations in use. When the cold source medium is LNG, liquid nitrogen, liquid oxygen and other low-temperature media, there are certain requirements for the taste of the heat source medium. If water is used for heating, the water temperature is required to be at 20°C Above, in order to prevent the water from freezing during the heating process, which will affect the safe and stable operation of the equipment. [0003] For occasions with a large number of low-grade heat sources, such ...
