Problems solved by technology

[0002] At present, most metallurgical factories use old-fashioned boilers for heating. The old-fashioned boilers directly discharge the high-temperature flue gas generated by the holding furnace into the air, and a lot of heat is directly discharged into the atmosphere, which is neither energy-saving nor environmentally friendly.

Embodiment Construction

[0009] In order to make the implementation technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0010] Such as figure 1 As shown, the waste heat recovery and utilization energy-saving device includes a holding furnace 1, a waste heat pipe 3 is arranged on the holding furnace 1, and the other end of the waste heat pipe 3 leads to the reverberatory furnace 2, and a valve 4 is also provided on the waste heat pipe 3.

[0011] When the present invention is working, it is only necessary to open the valve 4 on the waste heat pipe 3, so that the high-temperature flue gas in the holding furnace 1 will not be directly discharged into the air, but will enter the reverberatory furnace 2 through the waste heat pipe 3 to preheat the material. The material heating time in the reverberatory furnace 2 is shortened, and the energy saving effect...

Abstract

A waste heat recycling energy-saving device comprises a holding furnace, a waste heat pipe is arranged on the holding furnace, the other end of the waste heat pipe leads into a reverberatory, and a valve is arranged on the waste heat pipe. Compared with the prior art, the waste heat recycling energy-saving device is simple in structure, heat discharge in the holding furnace is reduced, the material temperature-rising time in the reverberatory is shortened, and the device saves energy and is environmentally friendly.

Description

technical field [0001] The invention and the field of metallurgy specifically relate to an energy-saving device for waste heat recovery and utilization. Background technique [0002] At present, most metallurgical factories use old-fashioned boilers for heating. The old-fashioned boilers directly discharge the high-temperature flue gas generated by the holding furnace into the air, and a lot of heat is directly discharged into the atmosphere, which is neither energy-saving nor environmentally friendly. In order to improve thermal efficiency and make full use of waste heat, an energy-saving device for waste heat recovery and utilization is urgently needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving device for recovery and utilization of waste heat, so as to solve the problems raised in the above-mentioned background technology. [0004] The technical problem solved by the present invention a...
