[0001] The present application relates to the technical field of nickel alloy smelting, and in particular to a nickel alloy smelting waste gas recovery device. Background Art

[0002] The waste gas generated during the nickel alloy smelting process mainly contains harmful substances such as dust, oxides, nitrides and sulfides. In order to protect the environment and the air quality in the workplace, these waste gases need to be treated.

[0003] The Chinese patent with publication number CN216654068U discloses a nickel alloy smelting waste gas recovery device. By setting a cooling box, the incoming waste gas can be cooled, and by setting an alkaline liquid, the waste gas can be deacidified. The stirring mechanism on the treatment tank can stir the alkaline liquid to prevent precipitation during use and reduce the effect of waste gas treatment.

[0008] By adopting the above technical scheme, the smelting waste gas includes dust and toxic gases, and the temperature is relatively high. After the smelting waste gas enters the filter box, water is sprayed into the filter box through the flushing component to cool the smelting waste gas. The mixture of dust and water falls under the action of gravity, so that solid impurities such as dust are separated from the gas, preventing the impurities in the gas from condensing and adhering to the inside of the equipment and clogging the exhaust pipe, and facilitating subsequent recycling and treatment.

[0017] Optionally, the driving assembly includes a driving cylinder, one end of which is fixedly connected to the filter box, and a push rod is provided on the pneumatic rod of the driving cylinder.

[0018] By adopting the above technical solution, the pneumatic rod of the cylinder drives the push rod to push the assembly box, so that the assembly box moves in the filter box. After the activated carbon adsorption plate is installed, the driving cylinder can be started to reset the activated carbon adsorption plate.

[0019] Optionally, a first magnet is disposed at the end of the push rod, and a second magnet is disposed on one side of the assembly box, and the first magnet and the second magnet are disposed opposite to each other and are attracted to each other.

[0020] By adopting the above technical solution, by setting the first magnet and the second magnet, the driving cylinder pushes the assembly box to close the filter box. When the driving cylinder drives the push rod to return, the assembly box is pulled back under the action of the magnetic force of the magnet. When the push rod is driven back, the assembly box is pulled out under the action of the magnetic force of the magnet, which makes it convenient for the staff to replace the activated carbon adsorption plate.

By setting up a water pump, a water tank, a water spray pipe, a water outlet, a water pump and a water outlet pipe, the water pump draws water from the water tank, flows through the water spray pipe through the water outlet and sprays water mist onto the exhaust gas. The water mist adheres to the dust, so that the dust and other solid impurities are separated from the gas, and the dust particles are moistened and settled. The wet dust removal method can simultaneously remove some harmful gases and smoke in the exhaust gas, and cool down the high-temperature gas to prevent the smelting exhaust gas from affecting the normal operation of the device;
