High-efficiency gasification device suitable for multiple kinds of coal

Abstract

The invention discloses a high-efficiency gasification device suitable for multiple kinds of coal. The high-efficiency gasification device comprises pulverized coal conveying equipment, a gasification furnace and synthesis gas purification equipment, wherein the pulverized coal conveying equipment comprises a charging tank, two or three pulverized coal locking hoppers are arranged above the charging tank, each pulverized coal locking hopper is connected with the top of the charging tank through a discharging pipe, locking hopper equalizing pipes are connected among the three pulverized coal locking hoppers; a charging pipe is arranged at the bottom of the charging tank, the charging pipe is connected with a feeding opening of the gasification furnace; the gasification furnace is connected with the synthesis gas purification equipment. The high-efficiency gasification device is used for improving the existing pulverized coal conveying equipment, gasification furnace and synthesis gas purification equipment so as to have the advantages of convenience in regulating a load, wide coal application range, high gasification efficiency and carbon conversion rate, high synthesis gas washing efficiency, excellent treating capability of a slag-water system, and the like; a solution or available commercial selection is provided for solving the problem existing in the prior art.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-efficiency gasification device applicable to multiple coal types. Background technique [0002] Coal gasification technology, especially high-pressure, large-capacity entrained-bed gasification technology, has shown its good economic and social benefits, represents a development trend, and is currently the cleanest coal utilization technology. The current gasification bed gasification technology is mainly divided into coal water slurry technology represented by Texaco and dry coal powder technology represented by SHELL. Among them, the coal water slurry technology has disadvantages such as narrow coal type adaptability, low effective components of synthesis gas, and high consumption, while the SHELL gasification process has disadvantages such as complex process flow, large equipment investment, difficult system maintenance, and high technology transfer fees. A new type of...
