Problems solved by technology

[0002] 1. Atmospheric pressure fixed bed intermittent gasification technology is widely used in my country, but this technology spends 1 / 3 of the time for blowing gas, causing energy waste and environmental pollution, and the furnace temperature is not easy to control, which affects the quality of gas production
[0003] 2. Atmospheric fixed bed continuous gasification technology solves the problem of blowing gas discharge during the intermittent gasification process, but there are still problems that the temperature on the furnace is not suitable for control, and the carbon dioxide content in the production gas component is too high, which affects the quality of gasification

Abstract

The invention relates to a fixed-bed grading and gasifying continuous gas producing furnace comprising a raw material bin and a water jacket gasification furnace shell, wherein the raw material bin comprises material locking valves connected in series, the lower part of the water jacket gasification furnace shell is connected with two symmetrical slag discharging pipelines, each slag discharging pipeline is provided with the sealed material locking valves, three reaction areas are arranged in a gasification furnace, include a first reaction area, a second reaction area and a third reaction area from top to bottom and are respectively provided with a temperature monitoring device, and the three reaction areas are provided with three levels of gas distribution towers. The invention retains the integrative furnace type and the partial technical conditions of the fixed-bed intermittent gasification furnace, increases gasification temperature and gasification quality, meets the requirements on safety, environmental protection, energy saving, emission reduction and production cost reduction and provides a new route for fixed-bed gasification development.

Description

technical field [0001] The present invention adopts the continuous gasification technology of staged gasification of fixed bed at atmospheric pressure, which is a kind of continuous gasification of coal, coke or briquette by applying the action of gasification agent in the heat storage process, while maintaining the heat balance in the furnace, Make it form a continuous and stable gasification effect, produce semi-water gas suitable for synthetic ammonia and urea production, or produce water gas suitable for synthetic methanol production and a continuous gas furnace with high carbon monoxide content. Background technique [0002] 1. Atmospheric pressure fixed bed intermittent gasification technology is widely used in my country, but this technology is used for blowing gas for 1 / 3 of the time, causing energy waste and environmental pollution, and the furnace temperature is not easy to control, which affects the quality of gas production. [0003] 2. Atmospheric fixed bed cont...
