Abstract

The invention discloses a heat exchange system for a high temperature reactor and a high temperature reactor with the heat exchange system. The heat exchange system for a high temperature reactor comprises: a heat pipe evaporator having a first cooling water inlet and a first water vapor outlet; and a condenser for condensing water vapor, the condenser having A steam inlet and a condensed water outlet, the condensed water outlet communicates with the first cooling water inlet, the condensed water outlet is located above the first cooling water inlet, the steam inlet is connected to the first cooling water The steam outlet is connected. The heat exchange system according to the embodiment of the present invention has the advantages of high cooling water vaporization rate, high heat exchange efficiency, low equipment investment, and low operating cost.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a heat exchange system for a high temperature reactor, and also to a high temperature reactor with the heat exchange system. Background technique [0002] The gasification of dry powdered solid fuels (such as pulverized coal) has become the mainstream technology for the gasification of coal and other solid fuels due to its high cold gas efficiency, fast reaction speed, and low water and oxygen consumption. Dry pulverized coal gasification occurs at 1400-1700 degrees Celsius and the pressure is generally not higher than 4MPag. In order to protect the equipment from high temperature damage, the water wall is used to protect the gasifier and other equipment. [0003] At present, the water-cooled walls used in equipment such as gasifiers are divided into two types according to the heat exchange tube structure: vertical tube film type and coil tube type. [0004] Patent application...
