Gasifier for organic solid waste by injection into molten iron and slag bath

A gasifier for organic solid waste by injection into molten iron and slag bath, comprising a gasification furnace, a liquid level adjusting furnace and a slag discharge and heat exchange shaft furnace, wherein, the gasifier is configured to blow organic solid waste into a molten iron bath and a molten slag bath floating on the molten iron bath, to perform ultra-high temperature pyrolysis and react with a gasifying agent to produce combustible syngas;

• the gasification furnace is closed, and at least one particle material injection lance, installed at a side wall of the gasification furnace, is configured to inject solid particles and is immersed in the molten slag bath or the molten iron bath, and a supersonic jet injection lance is installed at the top of the gasification furnace e liquid level adjusting furnace;
• the liquid level adjusting furnace is closed, and a bottom of the liquid level adjusting furnace is in communication with a bottom of the gasification furnace through a communication pipe, an upper part of the liquid level adjusting furnace is provided with a molten iron pouring tank, the molten iron pouring tank is provided in communication with a sealing pressure-bearing mechanism, and a tapping hole is provided at the bottom of the liquid level adjusting furnace;
• and
• the slag discharge and heat exchange shaft furnace is in communication with an upper part of the gasification furnace, and the slag discharge and heat exchange shaft furnace is configured to hold liquid molten slag autonomously overflowing from the gasification furnace, to cool the liquid molten slag to a low-temperature solid phase, and to discharge the liquid molten slag.
