Embodiment Construction

[0019] Describe the present invention in detail below in conjunction with accompanying drawing and embodiment.

[0020] As shown in Figure 1 and Figure 2,

[0021] The waste heat utilization device on the surface of the rotary kiln includes a heat exchanger 2 arranged outside the surface of the rotary kiln body 1. The heat exchanger 2 has a heat-absorbing surface adapted to the surface shape of the rotary kiln body 1. The cross section of the rotary kiln body 1 is It is circular, and the heat-absorbing surface of the heat exchanger 2 is an arc surface concentric with the cross-section of the rotary kiln body 1, that is, the heat exchanger 2 is an arc-shaped plate sandwich structure, and the heat-absorbing surface faces the surface of the rotary kiln body 1, It is used to absorb the heat emitted from the surface of the rotary kiln body 1. The heat exchanger 2 has three heat exchanger units 201, 203 and 205, and the connecting pipes 202 and 204 are used to connect the heat excha...

Abstract

The invention discloses a residual heat utilizing device for the surface of a rotary kiln, which mainly solves the problem that residual heat resources of the surface of the rotary kiln can not be effectively utilized. The residual heat utilizing device for the surface of the rotary kiln comprises a heat exchanger which is arranged on the outer surface of the rotary kiln, the heat exchanger is provided with a heat-absorbing surface which is corresponded to the shape of the surface of the rotary kiln, the heat exchanger is fixed on a supporting stand, a relative position between the heat-absorbing surface of the heat exchanger and the surface of the rotary kiln is kept being stabled through the supporting stand, and the heat exchanger is provided with a water inlet and a water outlet. The heat exchanger is provided with a plurality of heat exchanger units, and each heat exchanger unit is connected through a communicating pipe. The heat exchanger adopts a curl plate type multilayered structure or a curl pipe range type structure, the water inlet of the heat exchanger is connected to a water outlet of a water pump, and the water outlet of the heat exchanger is connected to a hot-water tank. An electronic temperature controller can automatically measure water temperature and automatically control running the water pump according to a setting temperature. The invention can effectively absorb heat which is given off from the surface of the rotary kiln, and provide hot water with stable temperature.

Description

technical field [0001] The invention belongs to the technical field of waste heat utilization of a rotary kiln, and in particular relates to a device for utilizing the waste heat on the surface of a rotary kiln body. Background technique [0002] Rotary kiln is an important equipment widely used in cement, metallurgy, chemical industry and other industries. Especially in large-scale cement production enterprises, the rotary kiln is the key equipment that determines the cement output and heat consumption. Except for the equipment maintenance period, the rotary kiln is usually in a continuous operation state, and there is a large amount of waste heat on the surface that is continuously emitted all the year round. Even in the The cooling section of the rotary kiln also has stable waste heat resources at around 200°C. Since there are no feasible waste heat utilization measures, the waste heat on the surface of the rotary kiln cannot be effectively utilized, and a large amount of...
