Description

Technical Field

[0001] This utility model relates to the technical field of steel ladle smoke exhaust structure, specifically a heat storage steel ladle baking smoke exhaust structure. Background Technology

[0002] A steel ladle, also known as a steel container, steel bucket, or ladle, is a container used to hold molten steel during the steelmaking process. The molten steel is also refined within the ladle. A regenerative steel ladle is a device that uses heat storage technology to improve the heat preservation efficiency of the ladle. Since fumes are inevitably generated during the baking process, the exhaust structure for regenerative steel ladle baking is a system specifically designed to reduce environmental pollution and improve exhaust efficiency.

This regenerative steel ladle baking smoke exhaust structure with purification effect has the function of purifying smoke, effectively preventing smoke particles from being discharged into the atmosphere, and can sterilize the smoke, improving the working environment of workers and benefiting human health.

[0004] However, this utility model has the following problems in actual use:

[0005] Because the flue gas generated during the baking of the regenerative steel ladle is at a high temperature and contains water vapor produced during baking, directly discharging the flue gas into the purification structure for purification without cooling and dehumidification may lead to a decrease in its filtration efficiency, causing the filter material to soften or be damaged under high temperature and water vapor, thus losing its filtration effect.

[0016] (III) Beneficial Effects

Four brackets 13 are provided on the outer surface of the drive mechanism 12 to fix the drive mechanism 12 in a proper position.

[0029] Example 2:

[0030] In order to cool down the flue gas discharged from the ladle, a device cooler 6 and a refrigeration unit 7 are installed.

[0031] At the other end of the first connecting pipe 5 is a cooler 6 for cooling the flue gas. A chiller 7 for supplying condensate to the cooler 6 is located on one side of the cooler 6. Multiple cooling pipes 16 for flue gas passage are installed inside the cooler 6. An inlet pipe 17 for condensate to enter and an outlet pipe 18 for condensate to exit are located on the outer surface of the cooler 6. A first sleeve 19 for fixation is fixedly installed on the top of the cooler 6. A sealing cap 20 for closure is threaded onto the top of the chiller 7. Two mounting bases 21 for support are located at the bottom of the chiller 7. A second sleeve 22 for fixation is fixedly installed on the top of each mounting base 21. Therefore, the cooling pipes 16 are positioned... Inside the cooler 6, as the flue gas passes through these pipes, the heat is absorbed by the cooling medium, thereby reducing the temperature of the flue gas. The water inlet pipe 17 is located on the outer surface of the cooler 6 and is used to introduce condensate into the cooler 6. The water outlet pipe 18 is also located on the outer surface of the cooler 6 and is used to discharge the condensate injected into the cooler 6. The first sleeve 19 is fixedly installed on the top of the cooler 6 to fix the position of the cooler 6 and increase its stability during operation.

[0032] Example 3:

[0033] In order to perform water vapor adsorption and purification on the cooled flue gas during use, a device purification pipe 4 and a first connecting pipe 5 are provided.

[0034] One end of the blower 2 is fixedly installed with a purification pipe 4 for purifying flue gas, and the other end of the purification pipe 4 is fixedly installed with a first connecting pipe 5 for conveying flue gas. Two adsorption plates 14 for absorbing water vapor are installed inside one end of the purification pipe 4 and the first connecting pipe 5. Two filter elements 15 for purifying flue gas are installed inside the other end of the purification pipe 4. Therefore, the adsorption plates 14 are located inside the end of the purification pipe 4 connected to the first connecting pipe 5 to absorb water vapor in the flue gas. The adsorption plates 14 are made of water-absorbing material, which can reduce the humidity in the flue gas. The filter elements 15 are located inside the other end of the purification pipe 4 for further purifying the flue gas. The filter elements 15 can capture and remove particulate matter, harmful gases and other pollutants in the flue gas.

[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0036] In this invention, the working steps of the device are as follows:

[0037] First, the device is connected to the exhaust port of the ladle via the second connecting pipe 8, facilitating the intake of flue gas from inside the ladle. The flue gas then enters the cooler 6 through the second connecting pipe 8. The chiller 7 injects cold condensate into the cooler 6 through the water inlet pipe 17 to ensure the cooling pipe 16 and the cooler 6 remain cold. The condensate is then discharged through the water outlet pipe 18 on one side of the cooler 6 and re-enters the chiller 7, forming a water circulation and ensuring the condensate remains cold. The flue gas then enters the cooler 6 and is cooled by the cooling pipe 16. The cooled flue gas exits the cooler 6 and enters the first connecting pipe 5, which then enters the purification pipe 4. The water vapor in the flue gas is adsorbed by the adsorption plate 14 installed in the purification pipe 4, preventing the water vapor from affecting the purification quality of the filter element 15. The adsorbed flue gas passes through the filter element 15 to remove harmful substances. Finally, the purified flue gas is discharged into the air by the blower 2.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
