Embodiment 1

[0022] One of the specific implementations of a system for recovering waste heat from industrial waste gas by using heat transfer oil of the present invention, as figure 1 As shown, the industrial exhaust gas waste heat system includes a three-way valve 4 connected to the industrial exhaust gas source pipeline, one of the outlets of the three-way valve 4 communicates with the air cooler 6 through the bypass flue 5, and the air cooler 6 is connected to the ultra-low flue gas The discharge system 9 is connected; the other outlet of the three-way valve 4 is connected with the flue gas inlet of the heating module through the exhaust gas inlet flue.

[0023] In this embodiment, the heating module includes a heat collector 1 communicated with the three-way valve 4, and the heat collector 1 is connected to the industrial waste gas source pipeline and the ultra-low emission system 9 through the waste gas inlet flue and the waste gas outlet flue respectively. , the heat exchanger in th...

Embodiment 2

[0028] The second specific embodiment of a system for recovering waste heat from industrial waste gas by utilizing heat transfer oil of the present application, see figure 2 , the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the other outlet of the three-way valve 4 communicates with the flue gas inlet of the power generation module through the exhaust gas inlet flue.

[0029] In this embodiment, the power generation module includes a heat collector 1 communicated with a three-way valve 4, and the heat collector 1 passes through the waste gas inlet flue and the waste gas outlet flue respectively to the industrial waste gas source pipeline and the flue gas ultra-low emission system 9, The heat exchanger in the heat collector 1 is sequentially connected to the heat trans...

Embodiment 3

[0034] The third specific embodiment of a system for recovering waste heat from industrial waste gas by utilizing heat transfer oil of the present application, see image 3 , the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the other outlet of the three-way valve 4 communicates with the flue gas inlet of the heating module and the flue gas inlet of the power generation module respectively through the exhaust gas inlet flue, and the three-way valve 4 is connected with the heating module. There is a flue gas valve 16 between the modules, through which the exhaust gas inlet flue is controlled to communicate with the flue gas inlet of the heating module. When there is a demand for heating, the flue gas valve 16 can be opened to start the heating module. In Embodiment 3, the...

Abstract

The invention relates to the technical field of waste gas waste heat recovery, in particular to a system for recycling industrial waste gas waste heat by means of heat transfer oil. The system comprises a three-way valve which communicates with an industrial waste gas source pipeline, wherein one outlet of the three-way valve communicates with an air cooler through a bypass flue, and the air cooler communicates with a flue gas ultralow emission system; and the other outlet of the three-way valve communicates with a flue gas inlet of a heating module or / and a flue gas inlet of a power generation module through a waste gas inlet flue, and a flue gas outlet of the heating module or / and a flue gas outlet of the power generation module communicates with the flue gas ultralow emission system. The bypass flue is arranged and used as an emergency bypass device during system accidents or overhauling, and therefore sudden faults and maintenance of the system can be timely carried out; by utilizing waste heat of industrial waste gas, the system can selectively recycle heat or power generation, the waste heat of the waste gas can be fully utilized, reasonable arrangement can be carried out according to different regions and customer requirements, and the system has good applicability.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery from waste gas, in particular to a system for recovering waste heat from industrial waste gas by utilizing heat transfer oil. Background technique [0002] In iron and steel, metallurgy, building materials, chemical industry, machinery, light industry and other industries, various heating furnaces, smelting furnaces, rotary kilns, tunnel kilns, incinerators and other kiln equipment will produce a large amount of waste gas during the production process, and in the waste gas It will contain a lot of heat, and the waste heat of flue gas in some industrial kilns is even as high as 30% to 60% of the fuel consumption of the kiln itself. The potential for energy saving is huge, and it is one of the main objects of waste heat utilization. If it is discharged directly, it will cause a waste of resources and affect the climate and environment. [0003] Heat transfer oil, also known as heat carr...
