Example Embodiment

[0026] Next, the present invention will be described more completely with reference to the accompanying drawings, in which embodiments of the present invention are shown. However, the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented here. On the contrary, the provision of these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity. The same reference numerals denote the same elements throughout.

[0027] It should be understood that when a component is referred to as being "adjacent to" or "connected to" another component, it can be directly adjacent or connected to the other component, or there may be intervening components. In contrast, when a component is said to be "directly adjacent to" or "directly connec...

Abstract

The invention discloses a coaxial constant-speed turbine set for a blast furnace, which comprises an electric motor, a speed changer, a blast furnace blower and a high-speed blast furnace gas excess-pressure turbine, wherein the electric motor is connected to one side of the blast furnace blower through the speed changer; the high-speed blast furnace gas excess-pressure turbine is coaxially connected to the other side of the blast furnace blower; and a working rotating speed of the high-speed blast furnace gas excess-pressure turbine is as same as the working rotating speed of the blast furnace blower. The high-speed blast furnace gas excess-pressure turbine, a rotating speed of which (for example, 4800rpm) is as same as the rotating speed of the blast furnace blower, is selected and is coaxially connected to the blast furnace blower, thereby avoiding connecting the speed changer between the high-speed blast furnace gas excess-pressure turbine and the blast furnace blower, reducing the difficulty in designing an axis, promoting the utilization ratio of energy and reducing the demands on manufacturing and mounting of equipment.

Description

technical field [0001] The invention relates to the field of residual pressure and waste heat recovery, in particular to a blast furnace coaxial constant speed turbine train (Blast furnace Equal Speed ​​turbine Train, BEST). Background technique [0002] In the traditional blast furnace process system, in order to improve the utilization rate of energy, the blast furnace gas is usually led out, and then enters the inlet of the blast furnace gas residual pressure turbine after passing through the inlet butterfly valve, the flapper valve, etc. The formed flow channel is continuously expanded to do work, and converted into kinetic energy to act on the working wheel to make it rotate, and the working wheel drives the generator to rotate together through the coupling to generate electricity. [0003] In this system, the blast furnace gas residual pressure turbine converts the pressure energy and heat energy of the gas into mechanical energy, and then transfers it to the generator...
