Problems solved by technology

[0004] But the main problems existing in the existing grate cooler: insufficient clinker cooling degree, the clinker temperature at the clinker outlet is too high, higher than 200°C
The consequence is that the cement production process consumes more energy, and at the same time affects the quality of cement products.

Embodiment Construction

[0061] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0062] A grate cooler waste heat utilization system for cement production includes a grate cooler, figure 1 A cement production grate cooler 4 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, where the clinker rotates from The kiln 1 enters the grate cooler 4, and then transmits in the clinker channel 9 in the grate cooler 4. The fan 8 sends air to the grate cooler 4, and the temperature of the clinker is reduced by the wind, so that during the transmission process Cooling of the clinker is performed during the process, and the cooled clinker is output through the clinker outlet 7.

[0063] The clinker from the rotary kiln 1 is transported in the clinker channel 9 of the grate cooler, and is cooled by the wind conveye...

Abstract

The invention provides a heat-absorbing material-coated grate cooler waste heat recycling device and system. The device comprises barrels, wherein heat exchange tubes are arranged in the barrels; each barrel and the corresponding heat exchange tube are in a concentric circle structure; and a heat-absorbing material is coated on the outer surface of each barrel. According to the device and the system, the heat-absorbing material is arranged, so that the waste heat absorption can be further enhanced, the clinker energy consumption is reduced, and the utilization amount of waste heat also can be increased effectively.

Description

Technical field [0001] The invention relates to a waste heat recovery equipment coated with heat absorbing materials, belonging to the field of waste heat utilization and heat exchangers. Background technique [0002] The grate cooler (referred to as the grate cooler) is a major equipment in the cement production process. Its basic functions include: (1) Provide proper clinker cooling rate to improve cement quality and clinker grindability; (2) Increase the temperature of secondary air and tertiary air as much as possible, as combustion air, reduce the firing system Fuel consumption; (3) The waste heat air is heated for waste heat power generation and coal mill drying; (4) The clinker is crushed and cooled to the lowest possible temperature to meet the requirements of clinker transportation, storage and cement grinding Claim. The grate plate and the grate bed structure are the most important components of the grate cooler. It determines the thickness of the grate bed, as well a...
