Abstract

The invention relates to an adjustable heat collecting device for collecting heat dissipated by a rotary kiln body. The device is formed by connecting a plurality of independent heat collection units, wherein each heat collection unit comprises a heat collecting cover, a bracket and a position adjusting system; the heat collecting cover comprises a heated surface, a heat preserving material, a frame, a protective shield and the like; brackets are arranged on two sides of the rotary kiln body, the brackets on one side are directly connected with heat collecting shields, while the position adjusting systems are arranged between the brackets on the other side and the heat collecting covers; and each position adjusting system consists of a support mechanism and an execution mechanism. The heat collected from the rotary kiln body and the temperature of a heating working medium can be adjusted through the change of positions of the heat collection units, the connecting assembly way between the units of the heat collecting device and the change of the number of switching so as to ensure that the reclaimed heat and the surface temperature of the rotary kiln body are in a safe range, guarantee safe operation of the rotary kiln, and realize harmonization and unification of equipment safety, operation economy and heat reclaiming maximization.

Description

technical field

[0001] The invention relates to a heat collecting device, in particular to a collecting device for recovering the heat dissipation of a rotary kiln carcass. Background technique

[0002] At present, the international and domestic vigorously promote energy conservation and emission reduction, carry out clean production, and develop a low-carbon economy. The Chinese government promises that by 2020, the energy consumption per unit of GDP in my country will be reduced by 40-45%. The task of energy conservation and emission reduction is arduous.

[0003] In recent years, the cement industry has developed rapidly, and my country's cement output has exceeded half of the world's output. The cement industry is a high-energy-consuming industry. The recovery of waste heat from cement kilns is one of the key energy-saving projects in the "Eleventh Five-Year Plan" of the country. At present, the recovered waste heat is mainly the heat of waste gas at the kiln head and ki...
