[0002] Lead is one of the earliest metals used by humans. Currently, lead is primarily used in the manufacture of lead-acid batteries, solder, protective equipment for radioactive radiation and X-rays, and ammunition and artillery shells. The lead production process begins with smelting crude lead, followed by impurity removal and electrolytic refining. This crude lead smelting process often produces large amounts of smoke and dust, which contain numerous harmful substances such as lead dust and lead oxide, posing serious risks to the environment and human health.

[0003] Regarding the above-mentioned related technologies, the inventors believe that traditional smoke dust treatment devices are through liquid leaching, but due to the high air flow velocity, the leaching efficiency is often low and the equipment load is heavy. There are certain deficiencies in the treatment efficiency and treatment effect, and it cannot meet the increasingly stringent environmental protection requirements. Therefore, a lead-making smoke dust treatment device is proposed to solve the above problems.

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The embodiment of the present application discloses a lead fume treatment device. Figure 1-3 A lead-making smoke treatment device includes a smoke collection device 1, a pretreatment device 2, a main treatment device 3 and an exhaust gas treatment device 4. The smoke collection device 1 includes a dust hood 101 and a conveying pipe 102, and the dust hood 101 is fixedly connected to one end of the conveying pipe 102; the pretreatment device 2 includes a cyclone dust collector 201 and a bag dust collector 202; the main treatment device 3 includes a reactor 301 and an activated carbon adsorber 302, the inner cavity of the reactor 301 is filled with a catalyst, and the interior of the activated carbon adsorber 302 is installed with an activated carbon layer; the exhaust gas treatment device 4 includes a spray tower 401 and an exhaust fan 402, and the interior of the spray tower 401 is filled with an absorption liquid.

[0025] One end of the conveying pipe 102 away from the dust collecting hood 101 is connected to the air inlet end of the cyclone dust collector 201 .

[0026] The air outlet of the cyclone dust collector 201 is connected to the air inlet of the bag dust collector 202 through the first connecting pipe 5 .

[0027] The air outlet end of the bag filter 202 is connected to the air inlet end of the reactor 301 through a second connecting pipe 6 , and the second connecting pipe 6 is located at the end of the reactor 301 close to the bottom inner cavity of the reactor 301 .

[0028] The exhaust end of the reactor 301 is connected to the air inlet end of the activated carbon adsorber 302 through the first bellows 7 , and the exhaust end of the reactor 301 is higher than the liquid level of the liquid inside the reactor 301 .

[0029] The exhaust end of the activated carbon adsorber 302 is connected to the air inlet end of the spray tower 401 through the second bellows 8 , and the second bellows 8 is located at the end of the spray tower 401 close to the bottom inner cavity of the spray tower 401 .

[0030] The exhaust end of the spray tower 401 is connected to the air inlet port of the exhaust fan 402 through the air supply pipe 9, and the exhaust end of the spray tower 401 is arranged at the top thereof.

[0031] The implementation principle of a lead-making fume treatment device according to an embodiment of the present application is as follows: when in use, a dust hood 101 is placed above the lead-making equipment to collect the generated fume, and a conveying pipe 102 conveys the collected fume to a pre-treatment device 2. The pre-treatment device 2 includes a cyclone dust collector 201 and a bag dust collector 202. When the gas enters the cyclone dust collector 201 through the conveying pipe 102, the cyclone dust collector 201 removes large particles in the gas, and then the gas is conveyed into the bag dust collector 202 through the first connecting pipe 5. The bag dust collector 202 removes fine particles in the gas.

[0032] The gas is then transported into the main treatment device 3 through the second connecting pipe 6. The main treatment device 3 includes a reactor 301 and an activated carbon adsorber 302. The reactor 301 is filled with a catalyst. After the gas enters the reactor 301, the catalyst inside the reactor 301 converts harmful substances into harmless substances. The gas is then transported into the activated carbon adsorber 302 through the first bellows 7. The activated carbon layer in the activated carbon adsorber 302 removes the remaining harmful gases.

[0033] Finally, the gas enters the tail gas treatment device 4, which includes a spray tower 401 and an exhaust fan 402. The gas enters the spray tower 401 through the second bellows 8. The spray tower 401 is filled with an absorption liquid to absorb harmful substances in the tail gas, and the exhaust fan 402 discharges the treated tail gas in the spray tower 401 through the gas pipe 9.

[0034] It is worth noting that the outer walls of the second connecting pipe 6 and the second corrugated pipe 8 are both provided with one-way valves (not shown in the figure) to prevent the liquid in the reactor 301 and the spray tower 401 from flowing back.
