Abstract

The invention provides a cooling protecting device of a gasification furnace. The cooling protecting device of the gasification furnace comprises a cooling device. The cooling device is arranged at a connection section of a bottom tap of a gasification room of the gasification furnace and a chilling device. The cooling device comprises a water inlet pipe, a cooling coil, a water outlet pipe and a bending expansion bend. The cooling coil winds the inner side of the connection section of the bottom tap of the gasification room of the gasification furnace and the chilling device, the inlet and outlet of the cooling coil are separately connected to the water inlet pipe and the water outlet pipe, and the bending expansion bend is arranged in the inner side section of the inlet and outlet of the cooling coil. By organically combining the gasification room of the gasification furnace with the fast chilling device, the cooling coil is additionally arranged at the connection section of the bottom tap of the gasification room of the gasification furnace and the chilling device internally, cooling protection of a cooling dead zone is achieved, a hidden danger of high-temperature burnthrough is avoided, and long-term safe and stable operation of the system device is guaranteed.

Description

technical field [0001] The invention belongs to the field of gasification furnaces, in particular to a cooling protection device for a gasification furnace. Background technique [0002] At present, the pulverized coal water-cooled wall gasifier structure is in use, such as figure 1 As shown, its main components are: lower slag port 1 of the gasification chamber, quenching nozzle 2, quenching chamber 3, rapid quenching device 4, connecting section 5 between the lower slag port of the gasification chamber and the rapid quenching device. After the pulverized coal is combusted and gasified at high temperature in the gasification chamber, the high-temperature gas and fluid slag are sprayed in the quenching chamber 3 by the quenching nozzle 2 of the rapid quenching device 4 along the lower slag port 1 of the combustion chamber, and then enter the water bath type Cool the washing space, and send it out from the gasifier along the guide channel after cooling and washing.
