Embodiment approach
[0024] As an embodiment of the present invention, an opening 32 is provided in the swinging plate 3, and a telescopic plate 33 slides in the opening 32; The third spring 34, the third spring 34 is initially in a compressed state, and the right end of the telescopic plate 33 is designed with a slope; Squeeze the third spring 34 and put it in the opening 32; the telescopic plate 33 can prevent the solution from leaking during the swinging process of the swing plate 3, and at the same time make the solution and sediment flow into the first return pipe 42 more smoothly; As the pressure in the third cavity 27 continues to rise, the swing plate 3 moves down, and the expansion plate 33 is pushed out due to the action of the third spring 34, so that the expansion plate 33 slides against the side wall of the frame body 2 until it enters the first return pipe 42 , stop after contacting the side wall of the first return pipe 42, the sediment and water produced in the third cavity 27 ente...

The invention belongs to the technical field of steel smelting, and particularly relates to a waste gas treatment device for a steel smelting furnace. The device comprises a base, the steel smelting furnace, a frame and a controller; a first partition plate is arranged in the frame; the first partition plate is made of elastic high-temperature-resistant materials, and conical first through holes are uniformly formed in the first partition plate; an aeration pipe is arranged in a third cavity; the aeration pipe is spirally upwards designed, and aeration holes are uniformly formed in the surfaceof the aeration pipe; a swing plate is arranged below the aeration pipe; a material supplementing cabin is fixedly connected to the right end of the top of the frame; a first magnet and a second magnet are arranged in a sewage discharge pipe; sewage discharge holes are formed in the surfaces of the first magnet and the second magnet; a spray head is arranged in the third cavity; and a third magnet and a fourth magnet are arranged in a second reflux pipe, the third magnet and the fourth magnet are both circular, and second through holes are formed in the third magnet and the fourth magnet. According to the device, dust and sulfur dioxide gas in the waste gas can be completely removed, and the operation is simple and convenient.
Description
technical field [0001] The invention belongs to the technical field of steelmaking, in particular to a waste gas treatment device for a steelmaking furnace. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. Human beings have a long history of application and research on steel, but until the invention of the Bayesian steelmaking method in the 19th century, steel Production is a high-cost and low-efficiency work. Nowadays, steel has become one of the most used materials in the world due to its low price and reliable performance. It is indispensable in the construction industry, manufacturing industry and people's daily life. Composition, by putting the pig iron for steelmaking into the steelmaking furnace and smelting it according to a certain process, the steel can be obtained. Most of the steelmaking furnaces on the market are not equipped with dust treatment devices, but a large amount of dust...
