Technical Field

[0001] The utility model belongs to the technical field of copper methylsulfonate production, and particularly relates to an efficient tail gas absorption tower for copper methylsulfonate production. Background Technique

[0002] Tin methylsulfonate is currently the main raw material for electroplating tin, electroplating tin alloys, electroless plating tin, electroless plating tin alloys, etc. Metal surface tin plating and tin alloy plating are important processes in the production and manufacturing of current electronic components, printed circuit boards, etc. With the rapid development of the electronic industry, the demand for tin methylsulfonate is increasing day by day. Tin methylsulfonate combined with methylsulfonic acid, etc. is called the methylsulfonic acid electroplating system, which has great superiority compared with the previous fluoboric acid system and sulfuric acid system: its electroplating wastewater is relatively easy to treat; the coating quality is stable and reliable; high-speed electroplating can be achieved, improving production efficiency. During the production process of copper methylsulfonate, certain polluted tail gas will be generated, which cannot be directly discharged into the environment. It is necessary to absorb and filter this tail gas, and the treated gas can be directly discharged. Therefore, we design an efficient tail gas absorption tower for copper methylsulfonate production.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 :

[0020] Please refer to Figures 1 to 4 As shown, the embodiment of the present invention provides an efficient tail gas absorption tower for the production of copper methyl sulfonate, which includes a main body 1 of the tail gas absorption tower. One side of the top of the main body 1 of the tail gas absorption tower is communicated with an absorption exhaust pipe 2. The top of one side of the absorption exhaust pipe 2 is provided with an intake and exhaust control valve 3. One side of the main body 1 of the tail gas absorption tower away from the absorption exhaust pipe 2 is communicated with a circulation pipe 4. A gas pump 5 is fixedly installed on the surface of one side of the circulation pipe 4. The top of one side of the gas pump 5 is fixedly installed with a start control box 6. A power control valve 7 is arranged on one side of the circulation pipe 4 close to the gas pump 5. A control connection plate 8 is fixedly installed on one side of the power control valve 7. A gas substance content monitor 9 is fixedly installed on one side of the main body 1 of the tail gas absorption tower close to the circulation pipe 4. The bottom end of the main body 1 of the tail gas absorption tower is fixedly connected with a stable support foot plate 16.

[0021] In this embodiment, the absorption exhaust pipe 2 absorbs the tail gas to be treated into the interior of the main body 1 of the tail gas absorption tower. After being purified by a plurality of position filtering devices inside the main body 1 of the tail gas absorption tower, it flows to the bottom end inside the main body 1 of the tail gas absorption tower. At this time, the gas substance content monitor 9 directly monitors the gas content at the bottom end inside the main body 1 of the tail gas absorption tower in real time, and the monitored data is directly transmitted to the data display 92 for display, increasing the intuitiveness of detection. If the detection is unqualified, it is discharged through the circulation pipe 4 to the top end inside the main body 1 of the tail gas absorption tower again for gas filtering treatment;

[0022] A power connection line is provided between the control connection board 8 and the start control box 6, and the start control box 6 is electrically connected to the control connection board 8. A power connection line is provided between the gas substance content monitor 9 and the start control box 6, and the start control box 6 is electrically connected to the gas substance content monitor 9. A particle filter net 10 is fixedly installed on one inner wall of the main body 1 of the tail gas absorption tower. A photocatalyst filter net 11 is fixedly installed directly below the particle filter net 10 of the main body 1 of the tail gas absorption tower.

[0023] The particle filter net 10 can effectively filter out particulate matters such as dust and smoke in the tail gas. After passing through the particle filter net 10, the photocatalyst filter net 11 is made by doping the nano-scale powder and a variety of nano-scale light-sensitive semiconductor media in the lattice to ensure sufficient ventilation and contact, and then mixing and processing with the carrier. It can effectively remove harmful gases and odors such as carbon monoxide, nitrogen oxides, hydrocarbons, aldehydes, and benzenes in the tail gas, and can decompose them into harmless CO2 and H2O. Finally, the activated carbon storage tank 13 inside the absorption tank 12 absorbs certain harmful gases. At the same time, the activated carbon storage tank 13 can be replaced to increase the quantity. Multiple groups of activated carbon storage tanks 13 can be placed inside the absorption tank 12 for absorption use.

[0024] In this embodiment, the tail gas is absorbed into the main body 1 of the tail gas absorption tower through the absorption exhaust pipe 2. After being filtered by the particle filter net 10 and the photocatalyst filter net 11, and then absorbed by the absorption tank 12, the gas will reach the bottom end inside the main body 1 of the tail gas absorption tower.

When the detected value is too high, it will automatically control the start of the start control box 6. At the same time, the power control valve 7 is controlled to open, and the gas is pumped into the top end inside the main body 1 of the tail gas absorption tower to achieve the effect of filtering again, fully filtering, processing and absorbing to ensure that there are no harmful substances in the gas discharged subsequently.

An air suction pipe 94 is communicated with the back of the gas detection box 91. The number of the air suction pipes 94 is two, and the two air suction pipes 94 are symmetrically distributed at the bottom of the back of the gas detection box 91. The air suction pipe 94 extends into the interior of the main body 1 of the tail gas absorption tower. In this embodiment, by setting the gas substance content monitor 9, the gas is inhaled into the interior of the gas detection box 91 through the air suction pipe 94 for analysis, and the analyzed data is directly displayed on the data display 92. The staff can intuitively see the detected data content, reflecting the intuitiveness of the device use.
