Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to a smelting furnace for hydrogen storage alloys. Background Art

[0002] Hydrogen storage alloys are a new type of alloy that can absorb and release hydrogen under certain conditions. They have excellent cycle life and can be used in large batteries, especially in electric vehicles, hybrid electric vehicles, and high-power applications.

[0003] In the production process of hydrogen storage alloys in the prior art, the raw materials of the hydrogen storage alloy are generally put into a smelting furnace for melting and tempering. However, during the smelting and casting process of the hydrogen storage alloy, a large amount of high-temperature exhaust gas containing a large amount of smoke and dust is usually generated. This part of the high-temperature gas generated during the melting process is generally directly discharged into the air of the working environment through the exhaust valve. The gas is mixed with the odor of metal melting and high-temperature energy, which affects the working environment.

[0004] To facilitate exhaust gas purification, a search revealed a utility model patent with publication number CN219572647U, which discloses a smelting furnace with exhaust gas purification capabilities. The furnace comprises a main body, a conduit fixedly connected to the top of the main body, a flange fixedly mounted on the other end of the conduit, a blocking pipe fixedly connected to one end of the flange, and an air inlet pipe fixedly mounted on the other end of the blocking pipe via a flange.

[0005] During use of the above-mentioned prior art, exhaust gas enters the sealing pipe through the conduit, and then enters the outer shell through the air inlet pipe. The water pump is started to pump water in the water tank into the spray rack through the water pump pipe, and the water is sprayed out through the nozzles under the multiple fixed pipes, thereby knocking down the particulate matter in the exhaust gas, so that the cleaned exhaust gas is then filtered through the filter plate and then discharged through the exhaust pipe. However, the exhausted exhaust gas is also accompanied by a certain high temperature. Directly discharging this part of the high-temperature gas into the external environment is likely to cause a waste of resources. Utility Model Content
