Embodiment 1

[0062] Example 1: Combining figure 1 and figure 2 ; The heat recovery system applied on the wall of the rotary kiln is characterized in that the recovery system includes a rotary kiln 1, and the rotary kiln 1 can be supported by a bracket 11; the wall of the rotary kiln 1 is arranged from the outside to the inside. Outer protection steel plate 7. Insulation layer 8, reflection plate 9, heat exchange tube 10, wall surface of rotary kiln; the heat exchange tube 10 is a tube-and-tube heat recovery device, and the tube-and-tube heat recovery devices are arranged in parallel or in series; The type heat recovery device can exchange heat with the water of the heat user to supply the heat user. The substantive technical effect and realization process of the technical solution here are as follows: This part provides a specific realization structure and realization method, and the temperature of the wall surface of the rotary kiln is relatively stable and has high quality. For exampl...

Embodiment 2

[0064] Embodiment 2: As a further improved solution or parallel solution, the heat exchange tube 10 is connected with a constant pressure water supply device 1 51 , and the constant pressure water supply device 1 51 can supply water to the heat exchange tube 10 .

Embodiment 3

[0065] Embodiment 3: As a further improved solution or a parallel solution, the circulation pipeline of the heat user is connected to the second constant pressure replenishment device 52, and the second constant pressure replenishment device 52 can supply water to the circulation pipeline of the heat consumer.

Abstract

The invention relates to the field of heat transfer, in particular to a heat recovery system covering the wall face of a rotary kiln in a surrounding manner and a selecting method. The heat recovery system on the surface of the rotary kiln utilizes a tube type heat exchanger to recover afterheat and waste heat originally dispersed into environment during production, and the recovered heat is conveyed to heat users through a circulating water system to be utilized and can serve as heating water, air-conditioning water, bathing water, production technology preheating water and the like. The invention further provides a design and check method of a tube type heat recovering device of the heat recovery system on the surface of the rotary kiln. The theory basis is provided for designing and checking the heat recovery system on the surface of the rotary kiln. The system can totally or partially replace heat sources of heating, air-conditioning, domestic hot water, production technology preheating and the like, and an effective means of energy conversation and consumption reduction is provided for the high-energy-consumption equipment rotary kiln. The system can be used together with a heat storing system, a heat pump system and the like, and the use purpose is further expanded.

Description

technical field [0001] The invention relates to the field of heat transfer, in particular to a heat recovery system and a selection method for surrounding the wall of a rotary kiln. Background technique [0002] Because of its excellent mixing ability and good heat transfer performance, the rotary kiln is widely used in the sintering, roasting, volatilization, calcining, segregation and other processes of various materials in cement, chemical, metallurgical and other industries, such as bauxite Sintering, wood drying, Portland cement firing, lime calcination, dolomite calcination, carbon production, municipal waste incineration, tire pyrolysis, etc. However, it has the disadvantage of low energy efficiency and high energy consumption. China's industrial production has grown rapidly, and energy issues have begun to restrict the development of my country's social economy. Taking cement production as an example, the energy consumption of my country's building materials indust...
