Abstract

The invention provides a gasifier system and an operation process thereof. The gasification furnace system comprises a washing tower, a gasification furnace, a cooler, an ammonium separation tank and a compressor. The gasification furnace is provided with a synthesis gas outlet and a chilling gas inlet, the washing tower is provided with a synthesis gas inlet, a first chilling gas outlet and a second chilling gas outlet, the synthesis gas inlet is communicated with the synthesis gas outlet, and the cooler is provided with a coolant inlet, a coolant outlet, a chilling gas cooling inlet and a chilling gas cooling outlet. The first chilling gas outlet is communicated with the chilling gas cooling inlet, the ammonium separation tank is provided with a chilling gas-ammonium separation inlet, a chilling gas-ammonium separation outlet and a wastewater port, the chilling gas-ammonium separation inlet is communicated with the chilling gas cooling outlet, and the compressor is provided with a chilling gas compression inlet and a chilling gas compression outlet; the chilling gas compression inlet is communicated with the chilling gas ammonium separation outlet, and the chilling gas compression outlet is communicated with the chilling gas inlet. The problem that ammonium salt crystals in the chilling gas block a pipeline can be effectively solved.

Description

Technical field [0001] The present invention belongs to the field of coal gasification technology, specifically relates to a gasifier system and its operating process. Background [0002] The pressurized gasification technology of pulverized dry coal with its wide adaptability, high efficiency, low wastewater and green environmental protection has become the most important direction for the development of IGCC power generation and modern coal gasification technology. The IGCC power generation device adopts a two-stage gasifier as the gas head, which produces high-temperature syngas after being washed and washed into the gas turbine to generate electricity, and the by-product steam enters the steam turbine to generate electricity, so the power generation efficiency of IGCC is higher than that of conventional coal-fired power plants. [0003] The syngas temperature in the upper part of the gasification reaction zone of the IGCC gasifier is about 1500 °C, while the furnace roof tem...
