Abstract

The invention discloses a combined rotational flow bed gasification furnace comprising a rotational flow bed gasification furnace, a shell-tube type waste heat boiler and primary and secondary gas filter drain cocks, wherein the primary gas filter drain cock is arranged inside the rotational flow bed gasification furnace, and the top of the primary gas filter drain cock is level to the top of the rotational flow bed gasification furnace; the primary gas filter drain cock is in a cyclone separator form, and a water cooling coil is arranged on the side wall of the primary gas filter drain cock; a hot gas outlet of the primary gas filter drain cock is connected with a gas inlet of the shell-tube type waste heat boiler, an outlet of the water cooling coil is connected with a water inlet of the shell-tube type waste heat boiler, and a water outlet of the shell-tube type waste heat boiler is provided with an external steam supply connector and a steam connector used for the rotational flow bed gasification furnace; a gas outlet of the shell-tube type waste heat boiler is connected with the secondary gas filter drain cock, and a gas outlet of the secondary gas filter drain cock is provided with an external gas supply connector and a gas connector used for the rotational flow bed gasification furnace. The combined rotational flow bed gasification furnace is simple in equipment, low in manufacturing cost and small in water consumption, thus being applicable to the low-carbon conversion of low metamorphic coals.

Description

technical field

[0001] The invention relates to a coal gas generator, in particular to a combined swirl bed gasifier. Background technique

[0002] Coal gasification is the process of converting solid coal into gas. Coal gasification technology is widely used in the production of synthesis gas (production of synthetic ammonia, methanol, etc.), industrial fuel gas, city gas and other fields, and is an important part of clean coal technology. Coal gasification technology has a long history, especially when the oil crisis occurred in the 1970s, the research on coal gasification technology has been widely carried out in various countries in the world. So far, many gasification methods have been developed and are under research and development. It can be roughly divided into four categories: moving bed (fixed bed) gasification technology, fluidized bed gasification technology, entrained bed gasification technology, and molten bed gasification technology.
