Description

Technical Field

[0001] The utility model relates to the technical field of synthesis gas, in particular to a synthesis gas generating device. Background Art

[0002] Synthesis gas is a raw gas with carbon monoxide and hydrogen as the main components. It is widely used in the chemical industry. Its production methods are diverse. The main raw materials include carbon-containing substances such as coal, oil, natural gas and biomass. The composition of synthesis gas varies depending on the raw materials and production processes. It usually contains hydrogen, carbon monoxide, carbon dioxide, nitrogen and other components. In the chemical industry, synthesis gas is an important intermediate product used to produce chemical products such as ammonia and methanol. In addition, synthesis gas can also be used as fuel gas, which produces high calorific value after mixing with air. In the preparation process of synthesis gas, pulverized coal is usually used. In the gasifier, the pretreated pulverized coal is heated to a high temperature and a gasifying agent such as water vapor or air is injected. The pulverized coal reacts with the gasifying agent under high temperature to produce combustible gas.

The gasifying agent enters the gasifier and can only react to the surface of the coal powder, but has difficulty reacting to the bottom layer of the coal powder. This can easily lead to difficulty in fully mixing the coal powder and the gasifying agent, which can easily affect the generation of combustible gas. Utility Model Content
