Description

Technical Field

[0001] This application relates to the field of steelmaking and processing technology, and in particular to a dust removal spray device for converter steelmaking that allows for full contact with the reaction. Background Technology

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as main raw materials. Without the aid of external energy, it relies on the physical heat of the molten iron itself and the chemical reactions between its components to generate heat, thus completing the steelmaking process in the converter. Converters are classified as acidic or basic based on their refractory materials, and as top-blown, bottom-blown, or side-blown based on the location of gas introduction. They are also classified as air converters or oxygen converters based on the type of gas used.

[0003] A search revealed that patent document CN212476812U discloses a dust removal device for steelmaking converters, comprising a housing, a cylinder on one side of the housing, a cover plate on the top of the housing, a free end of the cylinder output shaft fixedly connected to the cover plate, a mounting cover fixedly connected to the bottom of the cover plate and fitted inside the housing, two symmetrically arranged filter bags inside the housing, the top of the filter bags penetrating the cover plate and the mounting cover, a dust inlet pipe on the top of the filter bags, rotating rods on the outer sides of the two filter bags, several brushes fitted on the outer sides of the rotating rods, a push frame between the two filter bags, and a half gear inside the housing, which is rotatably connected to the housing via a rotating shaft; the combination of the push plate and the brushes on the rotating rods can effectively treat the dust on the filter bags, effectively reducing their accumulation and improving the dust removal effect.

[0004] In practical use, it was found that the existing equipment is not thorough enough in removing dust from the flue gas generated by steelmaking, which can easily lead to the discharge of harmful gases into the outside environment and thus pollute the outside air. Therefore, we proposed a converter steelmaking dust removal spray device that can fully contact the reaction to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies, such as insufficient dust removal, which easily leads to the emission of harmful gases into the outside environment and thus pollutes the outside air.

The water pump 7 and the bottom box 1 are connected by a water pumping pipe. The same water inlet pipe 701 is provided between the water pump 7 and the annular spray seat 201. The water inlet pipe 701 is located in front of the air inlet pipe 10.

[0036] Specifically, a filter screen 101 is installed inside the bottom box 1, and the filter screen 101 is located above the water pump pipe.

[0037] Specifically, the cleaning mechanism includes a rotating rod 501, a brush holder 502, and a brush 503. The rotating rod 501 is fixedly installed on the output shaft of the motor 5. The rotating rod 501 is located inside the dust collection cylinder 2. The brush holder 502 is fixedly installed at the end of the rotating rod 501 away from the output shaft of the motor 5. A brush 503 is provided on the side of the brush holder 502 near the spray head 202. The brush 503 is adapted to the spray head 202.

[0039] Specifically, the dispersing mechanism includes a dispersing shaft 102 and a lever 103. The dispersing shaft 102 is rotatably mounted on the inner wall of the left side of the bottom box 1. The dispersing shaft 102 is located above the filter screen 101. The right end of the dispersing shaft 102 extends into the transmission box 3. The lever 103 is provided on the dispersing shaft 102.

[0041] In this application, during operation, the dust-laden flue gas first enters the dust collector 2 through the air inlet pipe 10 on the left side of the dust collector 2, and a certain amount of clean water is injected into the bottom box 1. The water pump 7 is started, and the water pump 7 draws water from the bottom box 1 through the water pumping pipe, and then transports the water to the annular spray seat 201 on the inner wall of the dust collector 2 through the water inlet pipe 701. The water is sprayed out in a mist from the spray head 202 at the bottom of the annular spray seat 201. Due to the reasonable layout and atomization effect of the spray head 202, the sprayed water mist can fully contact the dust entering the dust collector 2, so that the dust particles can be captured by the water mist and sink downward with the water flow under the action of gravity, thereby achieving the purpose of preliminary dust removal.

[0042] By starting the motor 5, the rotating rod 501 can be rotated, which in turn drives the brush holder 502 and the brush 503 to rotate. This allows the brush 503 to continuously clean the spray head 202, keeping it unobstructed and preventing it from being clogged by dust particles. At the same time, the motor 5 can drive the connecting rod 504 and the scraper 505 to rotate. The scraper 505 can then scrape away any dust, dirt, or other debris that may be attached to the inner wall of the dust collector 2, allowing it to fall smoothly into the bottom box 1. This maintains the cleanliness of the inside of the dust collector 2 and ensures efficient dust removal.

[0043] The motor 5 can drive the rotating shaft 6 to rotate through the transmission wheel 601 and the transmission belt 602, and can drive the dispersing shaft 102 and the deflector plate 103 to rotate through the bevel gear 603. This enables the deflector plate 103 to disperse the sewage falling from the drain port 9, and enables the wastewater to be evenly distributed on the filter screen 101. This also helps to prevent impurities in the sewage from accumulating locally on the filter screen 101 and affecting the filtration efficiency.

[0044] After being sprayed for dust removal, the gas flows upward and enters the filter box 8 at the top of the dust collector 2. The filter box 8 is equipped with an activated carbon adsorption layer. The activated carbon, with its porous structure, adsorbs residual fine dust particles and harmful gases such as sulfur dioxide, thereby further purifying the gas and ensuring that the discharged gas meets environmental emission standards, thus reducing the environmental pollution caused by the steelmaking process.
