Embodiment Construction

[0050] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] A grate cooler waste heat recovery system for cement production, including a grate cooler, figure 1A grate cooler 4 for cement production is shown. The grate cooler 4 includes a kiln head cover 2, a grate cooler shell 3, a high-temperature air outlet 5, a low-temperature air outlet 6, a clinker outlet 7 and a fan 8, wherein the clinker is rotated from The kiln 1 enters the grate cooler 4, and then transports in the clinker channel 9 in the grate cooler 4, and the fan 8 sends air to the grate cooler 4, and the temperature of the clinker is reduced by the wind, so that The clinker is cooled in the middle, and the cooled clinker is output through the clinker outlet 7.

[0052] The clinker from the rotary kiln 1 is transported in the clinker channel 9 of the grate cooler, and is cooled by the wind delivered by the fan. An insulating ma...

Abstract

The invention provides a waste heat recovery system for a cement production grate cooler employing square equipment. The grate cooler comprises a housing and a clinker channel, wherein a thermal insulation material is arranged between the housing and the clinker channel; waste heat recovery equipment is arranged in the thermal insulation material, and comprises at least one barrel; a heat exchange tube is arranged in the at least one barrel; the barrel is a rectangle; a plane is arranged at the lower part of the barrel. According to the grate cooler provided by the invention, sensible heat released by a clinker in a cooling machine in a fast cooling process can be fully absorbed; energy consumption of the clinker is reduced; the waste heat utilization rate can also be effectively increased.

Description

technical field [0001] The invention relates to a heat recovery system of a grate cooler, in particular to the heat recovery system of a grate cooler in cement production, and belongs to the field of F27D waste heat utilization and F28D heat exchanger. Background technique [0002] Grate cooler (referred to as grate cooler) is a major equipment in the cement production process. Its basic functions include: (1) Provide appropriate clinker cooling speed to improve cement quality and clinker grindability; (2) Increase the temperature of secondary air and tertiary air as much as possible, as combustion air, and reduce the temperature of the firing system fuel consumption; (3) heating the waste hot air for waste heat power generation and coal mill drying; (4) crushing the clinker and cooling it to the lowest possible temperature to meet the needs of clinker transportation, storage and cement grinding Require. The grate plate and grate bed structure are the most important parts ...
