[0002] Metal smelting waste gas is harmful gases and particulate matter produced during the metal smelting process. Its composition is complex and it poses significant risks to the environment and human health. Metal smelting waste gas contains a large amount of sulfides, smoke and metal particles, which can cause serious harm to the environment, leading to environmental problems such as acid rain and haze, causing damage to the ecosystem, exacerbating the global greenhouse effect and causing climate warming. The harmful substances in the waste gas can harm the human respiratory system, nervous system, etc. Long-term exposure may lead to various diseases.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 5 As shown, a metal smelting waste gas treatment device provided in this embodiment includes a dust removal device 200 and a desulfurization device 100. The dust removal device 200 is connected to the desulfurization device 100 through a first connecting pipe 302. The dust removal device 200 includes a dust removal tower 201. The lower side of the dust removal tower 201 is cooperated with the installation of an air intake pipe 304. One end of the first connecting pipe 302 is cooperated with the installation of the upper side of the dust removal tower 201. A hollow frame 208 is cooperated with the installation of the dust removal tower 201. The hollow frame 208 is connected to the air intake pipe 304 through a second connecting pipe 207. A number of nozzles 209 are cooperated with the installation of the lower side of the hollow frame 208. A number of baffles 204 are provided on the dust removal tower 201. Channels 205 are formed between the baffles 204. The channels 205 are serpentine. The baffles 204 are all bent plates. A number of heat dissipation fins 206 are cooperated with the installation of the bending parts of the baffles 204.

[0026] In this embodiment, the baffle 204 is a plate bent at an angle, and heat dissipation fins 206 are installed in the internal space formed by the bend. The heat dissipation fins 206 can be used to cool the flue gas. The cooled exhaust gas can make the next desulfurization work more stable.

[0027] The desulfurization equipment 100 includes a desulfurization tower 101, in which several spray desulfurization groups are installed. The spray desulfurization groups are arranged vertically. Each spray desulfurization group includes a spray coil 105 and a mesh disk 104. The spray coil 105 is located above the mesh disk 104. Several spray holes are opened on the lower side of the spray coil 105. Several glass balls 106 are placed on the mesh disk 104. A demister 107 is also installed in the desulfurization tower 101. The demister 107 is located above the spray desulfurization group. An outlet pipe 305 is also installed on the upper side of the desulfurization tower 101.

[0028] In this embodiment, the glass balls 106 are made of hollow glass, which has extremely high stability. When in use, the flue gas from bottom to top can pass through the gaps formed between the glass balls 106, thereby effectively allowing the desulfurization liquid sprayed from the spray coil 105 flowing from top to bottom to better contact the flue gas flowing from bottom to top, thereby effectively improving the desulfurization effect.

[0029] A pump station 301 is also provided on one side of the desulfurization tower 101. The pump station 301 is connected to the dust removal tower 201 through a first liquid replenishment pipe 202. The pump station 301 is connected to the dust removal tower 201 through a first mud discharge pipe 203. The pump station 301 is connected to the desulfurization tower 101 through a second liquid replenishment pipe 102. The pump station 301 is connected to the desulfurization tower 101 through a second mud discharge pipe 103. A flow control valve 303 is installed on the first connecting pipe 302.

[0030] It should be noted that when this embodiment is in use, it should be ensured that the liquid level line inside the dust removal tower 201 is lower than the highest point of the baffle 204, so that the dust removal liquid is contained in the channel 205, thereby increasing the dust removal effect. It should be ensured that the liquid level line in the desulfurization tower 101 is higher than the end connected to the first connecting pipe 302 and lower than the mesh disk 104. When the dust removal equipment 200 is in use, the exhaust gas can be introduced into the dust removal tower 201 through the diverter plate, the gas nozzle 209 is set downward, and a number of baffles 204 are installed on the diverter plate, and a serpentine channel 205 is formed between the baffles 204, which can make the gas stay in the liquid in the dust removal tower 201 for a longer time, so that the dust removal effect of the dust removal tower 201 is better, and the baffle 204 is also provided on the inside The heat dissipation fins 206 used for heat dissipation can further dissipate heat for other parts of the dust removal tower 201, so that the temperature of the flue gas drops significantly, making the next desulfurization work more stable. After the air intake completes dust removal, it enters the desulfurization tower 101, and the spray coil 105 sprays out the desulfurization liquid. The desulfurization liquid sprayed from the spray coil 105 flowing from top to bottom can better contact with the flue gas flowing from bottom to top, thereby effectively improving the desulfurization effect, thereby greatly increasing the working efficiency of the desulfurization tower 101, effectively preventing the accumulation of large particles of impurities in the desulfurization tower 101, effectively increasing the durability of the desulfurization tower 101, increasing the interval time between two maintenance of the desulfurization tower 101, and improving the stability of the exhaust gas treatment device.
