Embodiment Construction

[0055] The structural principle and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0056] See Figure 1A~Figure 1D , Figure 1A It is a schematic diagram of the structure of a waste heat recovery device according to an embodiment of the present invention ( Figure 1C A-A section view), Figure 1B for Figure 1A Top view of Figure 1C for Figure 1A The B-B section view, Figure 1D for Figure 1A Enlarged view of Part I. This waste heat recovery device is suitable for industrial furnace waste gas or gas containing viscous media. High temperature industrial furnace waste gas or gas enters the waste heat recovery device from the waste gas / gas inlet 13 at the upper end of the waste heat recovery device, and then passes through the diaphragm heating surface 21 to complete heat exchange During the process, the cooled industrial furnace exhaust gas or gas then flows out from the exhaust gas / gas outlet 14 at the lo...

Abstract

The invention relates to a waste heat recovery device for industrial furnace waste gas or coal gas. The waste heat recovery device comprises a cylindrical shell, and a heat exchange component, a soot blower, a working medium inlet collecting tank and a working medium outlet collecting tank which are arranged in the cylindrical shell, wherein the working medium inlet collecting tank and the working medium outlet collecting tank are respectively connected with the heat exchange component; the operating surface of the heat exchange component is a membrane type heated surface to damage an eddy zone of the heat exchange component so as to reduce the bonding degree of flying ash; the upper part of the membrane type heated surface is correspondingly provided with the soot blower, or the upper part and the middle part of the membrane type heated surface are correspondingly provided with soot blowers; and both ends of the cylindrical shell are provided with an industrial furnace waste gas/coal gas inlet and an industrial furnace waste gas/coal gas outlet so as to ensure that the industrial furnace waste gas/coal gas can fully scour the membrane type heated surface. The waste heat recovery device effectively solves the problem of removal of sticky ash and ultra-fine ash, the consecutive operation time of the waste heat recovery device is prolonged, and the heat exchange efficiency of the waste heat recovery device is improved.

Description

Technical field [0001] The invention relates to a waste heat recovery device, in particular to a waste heat recovery device that uses a membrane heating surface to recover waste heat from industrial furnace waste gas or coal gas containing a viscous medium. Background technique [0002] In the current situation of the world's energy crisis, energy saving and emission reduction is a long-term established national policy of our country. There are a large number of industrial furnaces and gas production facilities in our country. These kilns and facilities will produce exhaust gas with a temperature much higher than the ambient temperature or gas with a temperature higher than the required temperature of the next process during operation. Before the exhaust gas is discharged or the gas enters Before the one-step process, a heat exchanger needs to be installed to lower the temperature of the exhaust gas or coal gas, so as to achieve the purpose of waste heat recovery. [0003] Some in...
