Chilling process gasifier with high-temperature heat recovery unit

Abstract

The invention discloses a chilling process gasifier with a high-temperature heat recovery unit, which comprises an upper gasification / combustion chamber, a middle radiation waste pot with high-temperature heat recovery function and a bottom washing and cooling chamber, wherein the top of the gasification / combustion chamber furnace body or a certain plane on the periphery of the furnace body or a plurality of planes is / are provided with one or a plurality of nozzles; the radiation waste pot is composed of a flange connected with the gasification / combustion chamber, an interface water cooling coil pipe, a single-channel water cooling wall, a water cooling coil pipe connected with the washing and cooling chamber, and the like; the washing and cooling chamber is mainly composed of a chilling water ring and a down pipe; and the upper part of the side surface of the washing and cooling chamber is provided with a synthetic gas outlet. The chilling process gasifier can enhance the adaptability to coal types, effectively recovers the high-position sensible heat of the gasification product, and is suitable for a process unit for preparing synthetic gas and an integral coal gasification combined cycle generation system. Compared with the traditional waste-pot process gasifier, the chilling process gasifier is simpler in structure and convenient for manufacturing and maintenance, and has higher popularization and application values.

Description

technical field [0001] The invention belongs to the field of coal gasification, and relates to an entrained flow gasification furnace with a radiant waste pot and a washing cooling chamber, which can recover the sensible heat of high-temperature syngas after gasification and use it to prepare syngas (CO+ h 2 ) gasification device. Background technique [0002] As a basic energy source and an important raw material, coal has an important strategic position in national economic and social development. The coal chemical industry is an important industry for the clean and efficient conversion of coal. After decades of development, the overall technical level of my country's coal chemical industry has developed rapidly, but there are still problems such as high energy consumption, serious pollution, and low resource utilization. High-efficiency and energy-saving coal gasification technology is the core technology and leading technology for the development of the coal chemical i...
