Problems solved by technology

[0002] The heat recovery of the gasifier has become the main means of saving energy and reducing consumption, so it is necessary to have a radiant heat recovery component with a large enough heat exchange area to absorb the radiant heat generated by the crude gas. However, the radiant heat recovery component in the prior art usually uses One-piece manufacturing and molding are difficult to manufacture and difficult to install in the later stage. This has become the technical bottleneck of the existing structural form of radiant heat recovery components with a large heat exchange area, which limits the development of energy-saving gasifiers to high-volume high-yield targets.

Abstract

The invention discloses an independent screen type radiation heat recovery assembly applied to a gasifier. The independent screen type radiation heat recovery assembly comprises an upper gathering collection box and a lower gathering collection box; the upper gathering collection box is provided with a water vapor outlet; the lower gathering collection box is provided with a boiler water inlet; the upper gathering collection box communicates with the lower gathering collection box through shell protection screens and radiation screens; and the radiation screens are arranged on the inner sides of the shell protection screens. According to the independent screen type radiation heat recovery assembly, the problems that an existing radiation heat recovery assembly is high in equipment cost and high in manufacturing difficulty, and cannot be easily repaired are solved, and enlargement and automation of radiation heat recovery assembly manufacturing are achieved, so that the independent screen type radiation heat recovery assembly lays a foundation for the assumption of building the large-capacity high-yield energy-saving type gasifier.

Description

technical field [0001] The invention relates to the technical field of coal gasification, in particular to an independent panel type radiant heat recovery component applied to a gasification furnace. Background technique [0002] The heat recovery of the gasifier has become the main means of saving energy and reducing consumption, so it is necessary to have a radiant heat recovery component with a large enough heat exchange area to absorb the radiant heat generated by the crude gas. However, the radiant heat recovery component in the prior art usually uses One-piece manufacturing and molding are difficult to manufacture and difficult to install in the later stage. This has become a technical bottleneck for the existing structural form of radiant heat recovery components with a large heat exchange area, which limits the development of energy-saving gasifiers to high-volume high-yield targets. Contents of the invention [0003] The purpose of the present invention is to prov...
