Abstract

The invention discloses a radiation waste boiler chilling integrated sensible heat recovering device. The radiation waste boiler chilling integrated sensible heat recovering device comprises a housingprovided with a crude synthesis gas inlet, a radiation waste boiler and a residue discharging pool, wherein the radiation waste boiler is installed in the housing and defines a heat exchanging area and a chilling area from top to bottom, a synthesis gas upstream channel is formed between the chilling area and the housing, and the synthesis gas upstream channel is provided with a synthesis gas outlet. The radiation waste boiler comprises a water cooling wall, a first group of water cooling shields, a second group of water cooling shields and a chilling component, wherein the water cooling wallis installed in the heat exchanging area and the water cooling wall defines a gas-residue channel; the first group of water cooling shields comprises multiple first water cooling shields, the multiple first water cooling shields are slantwise distributed at intervals along a circumferential direction of the gas-residue channel and defines a first heat exchange channel of which a cross section area is gradually reduced from top to bottom, the second group of water cooling shields comprises multiple second water cooling shields, the multiple second water cooling shields are distributed at intervals along the circumferential direction of the gas-residue channel and defines a second heat exchange channel, the second water cooling shields correspond to and communicate with the first water cooling shields; the chilling component is installed in the chilling area; and the residue discharging pool is connected with the lower end of the housing, the lower end of the chilling area is extended into the residue discharging pool.

Description

technical field [0001] The invention belongs to the field of boilers, in particular, the invention relates to an integrated sensible heat recovery device for radiating waste boiler chilling. Background technique [0002] A gasifier with a radiant waste pot can digest coal with high sulfur, high ash, and high ash melting point, realize the localization of raw coal, solve the gasification problem of Shanxi's "three high" coal, and also become a national "three high" Coal comprehensive utilization and gasification provide new methods and means; it is of great significance for Shanxi Province to transform traditional coal chemical industry and develop new coal chemical industries such as coal-to-natural gas, coal-to-oil, coal-to-olefin, and coal-to-ethylene glycol. By installing a radiation waste boiler device inside the gasifier, during the operation of the equipment, by recovering the heat of high-temperature and high-pressure syngas and by-producting high-temperature and high...
