DETAILED DESCRIPTION

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, an industrial exhaust gas waste heat recovery device is used for the recovery and reuse of high-temperature exhaust gas in industrial production. In use, a gas transmission pipe 5 is connected to the exhaust gas outlet of the industrial production equipment, allowing the produced exhaust gas to be input into the connecting pipe body 8 via the gas transmission pipe 5. Simultaneously, the connecting pipe body 8 is connected to the base 9 at the bottom of the insulation box 1, allowing the high-temperature exhaust gas to be transported into the insulation box 1. During the transport of the exhaust gas within the connecting pipe body 8, the built-in filter element 18 filters the exhaust gas, adsorbing dust and harmful impurities carried in the exhaust gas, improving the purity of the recovered exhaust gas, and thus improving the heating efficiency of the exhaust gas. The filter element 18 is fixed to the front end of the connecting pipe body 8 by two sets of mounting plates. The connecting plates 17 and slots 16 on the inner walls of the two sets of mounting plates are engaged to fix the filter element 18, making cleaning the filter element 18 more convenient, reducing environmental pollution, and improving the utilization efficiency of the exhaust gas.

[0022] Example 2, as Figures 1-4 As shown, an industrial exhaust gas waste heat recovery device is disclosed. After the exhaust gas is filtered and transported through the connecting pipe 8, it is directly transported to the base 9 at the lower end of the insulation box 1. The insulation box 1 can be equipped with a heating furnace 12. The heating seat 20 at the lower end of the heating furnace 12 is connected to the fixed seat 11 inside the insulation box 1 to complete the assembly of the heating furnace 12. At this time, the high-temperature exhaust gas stored in the base 9 can flow upward through the ventilation channel 10 and flow into the fixed seat 11, thereby continuously heating the bottom of the heating furnace 12 to achieve the effect of recovering heat energy. The residual exhaust gas after heating can be discharged to the outside of the device through the exhaust pipe 3. After the exhaust gas continuously heats the heating furnace 12, it can serve as hot water and heat industrial materials depending on the contents of the heating furnace 12.
