Inflation box fixed grate bed of grate cooler

Abstract

The invention discloses a partition combined inflation box fixed grate bed of a cement clinker grate cooler. The inflation box fixed grate bed comprises a combined inflation box; the combined inflation box consists of at least two combined modules; the combined modules comprise air chambers, and grate plates arranged on the air chambers; each air chamber of each combined module is divided into multiple subareas communicating with a fan; each air chamber of each combined module at the end part of a feed end is divided into at least two subareas transversely arranged; and each air chamber of each rest non-end combined module is divided into at least three subareas transversely arranged. The fixed grate bed has the characteristics of compact structure assembly, low failure rate, high heat recovery efficiency and convenience to maintain; each air chamber of each combined module of the fixed grate bed is divided into multiple subareas; and aiming at different material layer thicknesses anddifferent material layer porosities, corresponding reasonable air volumes and air pressures are set.

Description

technical field [0001] The invention relates to an air-filled box-fixed grate bed of a grate cooler, in particular to a cement clinker grate cooler fixed grate bed with partitioned and combined air-filled boxes. Background technique [0002] The cement clinker grate cooler is an important thermal process equipment in the cement clinker production line of the cement plant. Conveying, storage, grinding and cement properties. The use effect of the cement clinker grate cooler mainly depends on its performance. In the current cement production, the third-generation fixed bed of the cement clinker grate cooler is composed of multi-product fixed beams. The upper plane of the fixed beams is equipped with an inflatable grate plate. The entire fixed grate bed is an independent air chamber, the fixed beam cooling air is supplied by 1 to 2 high-pressure centrifugal fans alone, and the air chamber cooling air is supplied by a high-pressure centrifugal fan alone. It is difficult to bala...

The use effect of the cement clinker grate cooler mainly depends on its performance. In the current cement production, the third-generation fixed bed of the cement clinker grate cooler is composed of multi-product fixed beams. The upper plane of the fixed beams is equipped with an inflatable grate plate. The entire fixed grate bed is an independent air chamber, the fixed beam cooling air is supplied by 1 to 2 high-pressure centrifugal fans alone, and the air chamber cooling air is supplied by a high-pressure centrifugal fan alone. It is difficult to balance the air volume and air pressure with the air volume and air pressure of the air chamber fan, and it is easy for the fan to return to the air; the fourth-generation fixed bed, the entire fixed bed is an independent air chamber; due to the unreasonable structure of the traditional grate cooler, due to The discharge method of the rotary kiln is falling from a high altitude, and the high-temperature cooking that falls on the fixed grate bed produces coarse and fine segregation. The material layer at the edge is easily blown through and the phenomenon of "open air flow" occurs. Not only the grate plate and guard plate are easily damaged, but also the clinker from the grate cooler is not cooled effectively, because the high-temperature clinker cannot be cooled rapidly at the feeding end, and a reduction phenomenon occurs in the grate cooler, which affects the clinker transportation and storage , grinding and cement properties
