Gasification furnace comprising synthesis gas chilling device and use method of gasification furnace

Abstract

The invention aims to provide a gasification furnace comprising a synthesis gas chilling device and a using method of the gasification furnace. The problems that synthesis gas carries water and ash and ash is accumulated in the device are solved. For achieving the purpose, the invention provides the gasification furnace comprising the synthesis gas chilling device, and the gasification furnace comprises the chilling device arranged in the gasification furnace; the gasification furnace device comprises a furnace shell and a gasification chamber arranged in the furnace shell, and a gas guide pipe is connected to an outlet in the lower end of the gasification chamber. The chilling device is positioned below the gasification chamber; the chilling device comprises an inertia separation area, aliquid ash catching area and a liquid removing area, the inertia separation area, the liquid ash catching area and the liquid removing area are sequentially arranged on the two sides of the gas guidepipe from bottom to top, and the gas guide pipe vertically extends downwards into the chilling device and extends into a water bath arranged on the lower portion of the chilling device.

Description

technical field [0001] The invention relates to the field of gasification furnaces, in particular to a synthesis gas quenching device applied to gasification furnaces. Background technique [0002] The gasification technology uses fossil fuels such as coal and petroleum coke, biomass fuels such as plant straws, or carbonaceous substances such as household garbage as raw materials. The main purpose is to make carbonaceous raw materials into CO and H 2 Syngas as the main component converts the chemical energy in the carbonaceous raw materials into the chemical energy of syngas, and the syngas is used as fuel or raw material for subsequent processes. For example, the carbon-containing fuel and the gasification agent undergo an incomplete combustion reaction at high temperature, and most of the carbon and hydrogen elements in the fuel are converted into CO and H 2 . Gasification fuels, especially coal gasification, produce syngas with high temperature and high ash content. The...

Problems solved by technology

However, the chilling device in the form of a foam-breaking plate is prone to internal dust accumulation. The serious dust accumulation of the foam-breaking plate will lead to a decrease in the effect of chilling and ash removal, and even cause the system to shut down.
