Embodiment Construction

[0037] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] A heat pipe waste heat recovery system, comprising a heating device (i.e. a device that provides waste heat), a heat pipe 1, the heating device includes a casing, a channel, an insulating material is arranged between the casing and the channel, and the heat pipe 11 includes an evaporation end and a condensation end, the evaporation end of the heat pipe 11 is set in the heat preservation material.

[0039] Compared with common heat exchange tubes, the present invention can greatly improve heat absorption efficiency by arranging heat pipes as waste heat recovery pipes.

[0040] As preferably, the heating equipment is a grating cooler 4, for example, as figure 1 shown.

[0041] figure 1 A preferred 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-temperatu...

Abstract

The invention provides a heat pipe waste heat recycling system. The heat pipe waste heat recycling system comprises a heating device and heat pipes, wherein the heating device comprises a clinker passage, the heat pipes absorb heat energy in the clinker passage, and the spacing between every two adjacent heat pipes is gradually increased along the transportation direction of the clinker in the clinker passage. By utilizing the variable spacing between the heat pipes, the waste heat utilization efficiency can be greatly increased.

Description

technical field [0001] The invention relates to a waste heat recovery system, in particular to a grate cooler heat recovery system in cement production, and belongs to the fields of F27D waste heat utilization and F28D heat exchangers. 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 of the grate cool...
