However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0035] Example 1:

[0036] Please see Figure 1 - Figure 5 This is the first embodiment of the present invention.

[0037] This embodiment provides an acidic volatile gas recovery device, including: a neutralization tank body 1, an observation window 2, a drain pipe 5, and a glass tube level gauge 7; the observation window 2 is located at the front end of the neutralization tank body 1, the drain pipe 5 is fixedly installed on one side of the neutralization tank body 1 near the bottom, and the glass tube level gauge 7 is installed on the other side of the neutralization tank body 1, and also includes:

[0038] Exhaust assembly 3, intake assembly 4 and mixing assembly 6; intake assembly 4 is placed on one side above the neutralization tank body 1, intake assembly 4 is located on the other side above the neutralization tank body 1, and mixing assembly 6 is installed in the middle of the neutralization tank body 1.

[0039] The exhaust assembly 3 includes an exhaust pipe 31, an exhaust valve 32, and a first gas-liquid separator 33. The exhaust pipe 31 is fixed inside the neutralization tank body 1. The exhaust valve 32 is connected between the exhaust pipe 31 and the neutralization tank body 1 through a flange. The first gas-liquid separator 33 is fixedly connected to the end of the exhaust pipe 31.

[0040] The first gas-liquid separator 33 is a cyclone separator used to separate salt solution droplets in the exhaust pipe 31.

[0041] The air intake assembly 4 also includes an air intake pipe 41, an air intake valve 42, and a second gas-liquid separator 43. The air intake pipe 41 passes through the interior of the neutralization tank body 1. The air intake valve 42 is connected between the air intake pipe 41 and the neutralization tank body 1 through a flange. The second gas-liquid separator 43 is fixedly connected to the end of the air intake pipe 41.

[0042] The second gas-liquid separator 43 is a gravity separator used to separate acid mist droplets in the air inlet pipe 41.

[0043] Example 2:

[0044] Please see Figure 3 - Figure 5 This is the second embodiment of the present utility model.

[0045] For example, the mixing component 6 includes a servo motor 61, a rotating shaft 62, and a rotating plate 63. The servo motor 61 is fixedly mounted to the top of the neutralization tank body 1 by bolts, the rotating shaft 62 is fixedly connected to the power output end of the servo motor 61, and the rotating plate 63 is fixedly connected to the end surface of the rotating shaft 62.

[0046] The rotating plates 63 are evenly distributed at equal intervals along the end surface of the rotating shaft 62, and the surface of the rotating plates 63 is provided with a plurality of evenly distributed micropores at equal intervals.

[0047] The mixing assembly 6 also includes a mixing chamber 64, which surrounds the outside of the rotating plate 63. The rotating shaft 62 passes through the inside of the mixing chamber 64. The surface of the mixing chamber 64 is provided with a plurality of equidistant and uniformly distributed micro-holes. The servo motor 61 drives the rotating shaft 62 to rotate at high speed, causing the rotating plate 63 to be violently agitated in the mixing chamber 64. Due to the equidistant and uniformly distributed micro-holes on the surface of the rotating plate 63 and the mixing chamber 64, the rising gas bubbles and liquid flow are cut and crushed into finer scales under high-speed rotation, generating strong vortices and turbulence, which greatly increases the contact area and interface renewal rate of the gas and liquid phases. At the same time, the liquid is ejected at high speed through the micro-holes on the rotating plate 63 under the action of centrifugal force, forming a fine jet, which further breaks up the gas and enhances mixing.

[0048] The bottom of the intake pipe 41 is lower than the bottom of the exhaust pipe 31, and the intake pipe 41 is connected to the mixing chamber 64, which ensures that the gas is released from below the liquid surface and forces the gas to pass through the liquid layer to rise.

[0049] The observation window 2 is fitted with explosion-proof glass and is used to observe the neutralization tank body 1.

[0050] The working principle of the acidic volatile gas recovery device provided by this utility model is as follows:

[0051] In use, the exhaust port of the hydrochloric acid storage tank is connected to the air inlet assembly 4. At this time, the acidic gas containing acid mist and droplets first enters the system through the air inlet assembly 4. The second gas-liquid separator 43, a gravity separator, reduces the flow velocity and changes the flow direction of the acidic gas within the separator. Relying on the principle of gravity settling, the heavier acid mist droplets are separated from the gas. These droplets are captured and flow downwards into the bottom of the neutralization tank 1, initially reducing the load on subsequent processing and protecting internal components from direct impact and corrosion by large droplets. Subsequently, the pre-treated gas enters the interior of the neutralization tank 1 through the air inlet pipe 41. First, an alkaline neutralizing liquid is injected or continuously replenished. Since the bottom of the inlet pipe 41 is lower than the bottom of the exhaust pipe 31, it ensures that the gas is released from below the liquid surface, forcing the gas to pass through the liquid layer to rise. After the gas is released from the inlet pipe 41, it directly enters the mixing chamber 64 of the mixing component 6. At the same time, the servo motor 61 is started, driving the rotating shaft 62 to rotate at high speed, causing the rotating plate 63 to violently agitate inside the mixing chamber 64. Since the rotating plate 63 and the surface of the mixing chamber 64 are provided with equidistant and uniform micropores, the rising gas bubbles and liquid flow are cut and crushed into even finer particles under high-speed rotation. The high temperature generates strong vortices and turbulence, greatly increasing the contact area and interface renewal rate between the gas and liquid phases. Simultaneously, under centrifugal force, the liquid is ejected at high speed through the micro-holes on the rotating plate 63, forming fine jets that further break up the gas and enhance mixing. The equidistant, uniform micro-holes on the wall of the mixing chamber 64 allow the liquid to freely enter and exit, while restricting the disordered diffusion of large-scale vortices, concentrating energy on the esterification reaction zone inside the mixing chamber 64. In this enhanced turbulent environment, the acidic gas components undergo rapid acid-base neutralization with the alkaline neutralizing liquid, generating corresponding salts, which accompany the gas in the liquid phase. Through dissolution, diffusion, and chemical reaction, the target gas is efficiently absorbed and converted. The gas-liquid mixture after the reaction rises and leaves the mixing chamber 64 area. Since the gas phase inevitably carries some tiny droplets of salt solution generated in the reaction, after the gas enters the exhaust pipe 31, it flows through the first gas-liquid separator 33. The gas rotates at high speed along the spiral flow channel in the separator through the cyclone separator, generating a strong centrifugal force. The salt solution droplets, which are much denser than the gas, are thrown against the separator wall, gather, and flow down the wall back into the liquid at the bottom of the neutralization tank. The purified gas after separation is discharged through the exhaust valve 32.
