DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] like Figure 1-3 As shown, the utility model proposes a battery electrolyte production tail gas absorption device, including a tank body 1. One side of the tank body 1 is connected to a tail gas inlet 2, the other side is connected to an absorbent outlet 3, and the upper end is also connected to a tail gas outlet 4 for discharging the filtered tail gas. A spraying component 5 is arranged in the tank body 1, spraying an absorbent (the absorbent can react with harmful substances in the tail gas and absorb the harmful substances) on the tail gas passing into the tank body 1, and expanding the spraying range by rotating itself. A filter sponge 6 is arranged in the tank body 1 to absorb the absorbent droplets entrained in the tail gas. And a pressing component 7 is arranged on both sides of the filter sponge 6, pressing the filter sponge 6 to discharge the absorbent stored in the filter sponge 6.

[0023] Further explanation, the spray assembly 5 includes an annular chute 51 arranged on the inner wall of the tank body 1; a connection seat 52 is rotatably connected in the annular chute 51; a plurality of vents 54 for the exhaust gas to pass through are opened on the connection seat 52, a plurality of nozzles 53 are evenly connected at the lower end, and the upper end is connected and rotatably connected to a water pipe 55 arranged on the side wall of the tank body 1; the other end of the water pipe 55 is arranged through the tank body 1, and a water pump is arranged on it, which can pump the absorbent into 52 and spray it out along 53. By spraying the absorbent into the exhaust gas, the absorbent reacts with the harmful substances in the exhaust gas and absorbs the harmful substances, thereby eliminating the harmful substances in the exhaust gas.

[0024] Further, a gear ring 56 is provided at the upper end of the connection seat 52; a gear 57 is meshed and connected to one side of the gear ring 56; the gear 57 is coaxially connected to the driving end of a driving mechanism 58 provided on the tank body 1, and the driving mechanism 58 is a motor. By driving the connection seat 52 to rotate, the multiple nozzles 53 are all rotated, thereby increasing the range of the absorbent sprayed from the nozzle 53, increasing the contact range between the absorbent and the exhaust gas, and thus the harmful substances in the exhaust gas are absorbed more thoroughly.

[0025] Embodiment 2

[0026] like Figure 4-5 As shown, the utility model proposes a battery electrolyte production tail gas absorption device. Compared with the first embodiment, the present embodiment further includes: the pressing assembly 7 includes a lower filter screen 71 arranged at the lower end of the filter sponge 6 and an upper filter screen 72 arranged at the upper end of the filter sponge 6; both sides of the lower filter screen 71 are connected with a connecting plate 1 711; both sides of the upper filter screen 72 are connected with a connecting plate 2 721; the connecting plate 1 711 and the connecting plate 2 721 are both arranged in a placement rack 73 connected to the tank body 1; the upper end of the connecting plate 2 721 is connected with a sliding handle 77; the sliding handle 77 is arranged through the upper end of the placement rack 73 and is slidably connected to the placement rack 73.

[0029] The working principle of the utility model is as follows: when working, first open the air pump 401, let the battery electrolyte production tail gas pass through the tail gas inlet 2, and flow upward along the spray assembly 5 and the filter sponge 6 in sequence. Then start the water pump set on the water pipe 55, so that the absorbent flows along the water pipe 55 and is sprayed out from the nozzle 53, so that the absorbent reacts with the harmful substances in the tail gas and absorbs the harmful substances, thereby eliminating the harmful substances in the tail gas. Then start the driving mechanism 58 to drive the gear 57 to rotate, thereby driving the gear ring 56, the connecting seat 52 and the multiple nozzles 53 to rotate, thereby increasing the spray range of the absorbent, and then increasing the contact range between the absorbent and the tail gas, so that the harmful substances in the tail gas are absorbed more thoroughly. Then the tail gas continues to flow upward and passes through the filter sponge 6, the filter sponge 6 can absorb the absorbent droplets entrained in the tail gas, prevent the absorbent from overflowing and polluting the air, and finally make the clean tail gas discharged from the tail gas outlet 4.

[0030] When the filter sponge 6 is full of absorbent, the sliding handle 77 is pressed down to drive the second connecting plate 721 and the upper filter screen 72 to press down and squeeze the filter sponge 6, so that the absorbent in the filter sponge 6 is discharged, so that the filter sponge 6 can be reused to absorb more absorbent.
