Abstract

The invention discloses an anti-slag-blocking multi-layer water-cooled wall heat recovery device, in particular to a recovery device. The device aims to overcome the problems that in the prior art, due to the fact that a typical water pipe waste heat boiler has complex pipelines, headers and other structures in a synthesis gas circulation space, ash deposition, rooting points for growth, structural mutation, element wall temperature mutation and particularly superposition of the structural mutation and the element wall temperature mutation are formed, and consequently after the water pipe waste heat boiler device operates for a period of time, the heat exchange effect is influenced by ash accumulation, even shutdown cleaning is needed, the operation time cannot be guaranteed, and economic benefit loss is caused. A lower closing-in water cooling cylinder is arranged on an upper closing-in water cooling cylinder in a sleeved mode, an annular space is formed between the lower closing-in water cooling cylinder and the upper closing-in water cooling cylinder, the inner side wall of the lower closing-in water cooling cylinder is connected with the outer side wall of the upper closing-in water cooling cylinder, the upper portions of a plurality of enhanced water cooling screens penetrate through the upper portion of the upper closing-in water cooling cylinder and then extend outwards to the outside of a pressure shell, and a plurality of rapping dust removal devices transversely penetrate through the pressure shell and the lower closing-in water cooling cylinder in sequence from outside to inside in the horizontal direction. The device is used for recycling anti-blocking slag.

Description

technical field [0001] The invention relates to the field of anti-blocking slag recovery devices, in particular to an anti-blocking slag multi-layer water wall heat recovery device, specifically the technical field of high-temperature synthesis gas sensible heat recovery in coal chemical gasification section. Background technique [0002] Coal chemical crude synthesis gas has the characteristics of high temperature, high pressure, and high dust, especially the high dust content, which determines that its sensible heat recovery is difficult to achieve with fire tube waste boilers. The existing typical water pipe waste boiler technology has complex pipelines, headers and other structures in the syngas circulation space, forming rooting points for ash deposition and growth; in addition, structural mutations, component wall temperature mutations, especially the superposition of the two , is the primary reason for the sudden increase in the amount of dust accumulated in the corre...
