Technical Field

[0001] The utility model relates to the technical field of water seal tanks, in particular to a lithium battery waste gas water seal tank. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. During the production process of lithium batteries, waste gas is generated. The use of water seal tanks can treat the waste gas to achieve the purpose of neutralization and reduce the emission of harmful substances.

[0003] The water seal tank is generally composed of a tank body, an air inlet pipe, a water tank, a gas discharge pipe and an overflow port. When the waste gas from the lithium battery enters the water seal tank, it first enters the water tank through the air inlet pipe. At this time, the water in the water seal tank will block the gas, and most of the harmful substances are removed through the filtration and absorption of the water. The purified gas is then discharged from the water seal tank through the gas discharge pipe.

[0015] The utility model provides a lithium battery waste gas water seal tank, which has the following beneficial effects:

[0016] (1) The utility model provides an exhaust assembly. When a water seal tank is used to treat lithium battery waste gas, the lithium battery waste gas is discharged into the main body of the water seal tank from the waste gas pipe. The exhaust hole improves the problem of gas explosion sound when the waste gas passes through the water seal tank, so that the waste gas can pass through the water seal tank more smoothly, avoiding the unstable pressure fluctuation in the tank due to the pressure change of the gas, which will produce gas explosion sound and make it difficult for the waste gas to pass through the water seal tank, thereby reducing the waste gas treatment capacity of the water seal tank and improving the treatment effect of the water seal tank.

When the water seal tank is used to treat the waste gas of lithium batteries, the mounting frame contacts the waste gas to remove large particles in the waste gas, such as dust and particulate matter, to prevent the large particles from clogging the channel of the water seal tank or affecting the water absorption capacity, thereby reducing the treatment efficiency of the water seal tank. The treatment efficiency of the water seal tank is improved through filtering. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 to 4 As shown, a cooling fin 6 is installed on the inner wall of the exhaust pipe 3 .

[0032] When the water seal tank is used to treat the lithium battery waste gas, the exhaust gas is cooled by the refrigeration plate 6 to reduce the activity of harmful substances in the waste gas, making it easier to be treated, thereby improving the treatment effect of the water seal tank.

[0033] like Figures 1 to 7 As shown, the filter assembly includes a mounting frame 7 arranged inside the exhaust pipe 3, filter plates 8 are evenly installed inside the mounting frame 7, and an ash collecting box 9 is fixedly connected to the bottom end of the mounting frame 7.

[0034] By setting up the filtering component, when the water seal tank is used to treat the waste gas of the lithium battery, the mounting bracket 7 contacts the waste gas to remove large particles in the waste gas, such as dust, particulate matter, etc., to prevent the large particles from clogging the channel of the water seal tank or affecting the water absorption capacity, thereby reducing the treatment efficiency of the water seal tank and improving the treatment efficiency of the water seal tank through filtering.

[0035] like Figure 7 As shown, the ash box 9 is embedded in the bottom end of the exhaust pipe 3 , and the ash box 9 is connected to the exhaust pipe 3 via a connecting bolt 20 .
