Problems solved by technology

When recycling waste lead-acid batteries, the lead plate of the lead-acid battery will produce a large amount of harmful waste gas during the production process of smelting and reducing it to crude lead raw materials. If it is directly discharged into the air, it will cause air pollution.

Embodiment 1

[0025] This embodiment provides a waste gas treatment system for lead-acid batteries, such as figure 1 As shown, it includes the closed gas collection system 1 and the exhaust gas purification system 2. The two are integrated and connected, and each device in the system cannot operate independently. In addition, the system also includes drying and pre-desulfurization equipment 3 that can operate independently, which is used for pretreatment before the raw materials are put into the furnace. The pretreatment process adopts countercurrent negative pressure sealing technology, and the entire production process is fully negative pressure operation without any leakage of smoke.

[0026] Among them, the closed gas collection system 1 is a full negative pressure closed furnace, which is used to smelt the lead plates of waste lead-acid batteries. Open the furnace door and cause exhaust gas to leak out. The exhaust gas purification system 2 includes a dust removal system 21 , a power...

Abstract

The invention discloses a waste gas treatment system for lead-acid storage batteries and an application method of the waste gas treatment system. The system comprises a sealed gas collecting system (1) and a tail gas purification system (2) which are integrally connected and is characterized in that the tail gas purification system (2) comprises a dust removing system (21), a power system (22), adesulfurization system (23) and a discharge system (24); the dust removing system (21) comprises a multi-pipe settler and a bag-type dust remover (212); the desulfurization system (23) comprises a condensation desulfurizer (231), a sodium alkali desulfurization tower (232) and a calcium alkali desulfurization tower (233); the discharge system (24) comprises a discharge chimney (241) and an onlineflue gas detector (242) arranged in the discharge chimney (241). The application method of the waste gas treatment system includes: collecting waste gas, performing dust removing, performing desulfurization and discharging the waste gas. The waste gas treatment system has the advantages that flue gas purification efficiency can be increased, Pb discharge concentration is lowered greatly, and up-to-standard discharge of the waste gas generated by lead-acid storage battery lead melting is achieved.

Description

technical field [0001] The invention relates to the technical field of recycling waste lead-acid batteries, in particular to an exhaust gas treatment system for lead-acid batteries and a method for using the same. Background technique [0002] After the waste lead-acid battery is abandoned, whether it is in the atmosphere or buried deep in the ground, the shell of the battery will slowly corrode, and the heavy metal ions in it will gradually overflow with the seepage, dissolve in the soil or water and be absorbed by the root system of the plant. When livestock eat plants, they accumulate heavy metals in their bodies. Humans eat food, vegetables, meat, and water that contain heavy metals. Along this food chain, heavy metals will accumulate in the human body. Because heavy metal ions are difficult to excrete in the human body, they will eventually damage the human nervous system and liver function. Therefore, recycling waste batteries is of great significance to the protecti...
