Abstract
Description
Technical Field
[0001] The utility model relates to the field of CTP plate production and manufacturing, in particular to a sulfuric acid mist collection and processing device based on CTP plate production. Background Art
[0002] CTP plates are classified into four main types based on the platemaking imaging principle: photosensitive CTP plates, thermal CTP plates, ultraviolet laser CTP plates, and other systems. Alkali washing and neutralization are the process steps in the production of CTP plates. The degreasing process uses a 3% sodium hydroxide solution to spray and remove protective oil, impurities, and natural oxide film from the aluminum plate surface. After the alkaline wash, the remaining alkaline substances on the plate surface are removed with clean water. After cleaning, the plate is then pickled with sulfuric acid. Pickling uses an acid solution to remove scale and rust from the surface of steel plates. It is a method of cleaning the metal surface of CTP plates. However, the pickling process produces a lot of sulfuric acid mist, which can significantly pollute the on-site air environment and corrode production equipment. If accidentally inhaled by workers, it can also cause significant respiratory damage.
[0003] In view of the above problems, the present utility model is proposed. Utility Model Content

A liquid outlet pipe 14 connected to the interior of the treatment tank 1 is provided at the center of the lower surface of the treatment tank 1. The waste liquid generated after the sulfuric acid mist reacts with the alkaline solution is discharged through the liquid outlet pipe 14. A liquid inlet pipe 13 connected to the interior of the treatment tank 1 is provided above the surface of the treatment tank 1. The alkaline solution enters the treatment tank 1 through the liquid inlet pipe 13;
[0026] Multiple rows of circular tubes 2 are arranged at equal intervals from bottom to top in the treatment tank 1. The multiple rows of circular tubes 2 are parallel to the horizontal cross-section of the treatment tank 1. The multiple rows of circular tubes 2 are kept parallel. Multiple connecting vertical tubes 21 are vertically arranged between the upper and lower layers of circular tubes 2. The multiple layers of circular tubes 2 are interconnected through the connecting vertical tubes 21. The alkaline solution can pass through the connecting vertical tubes 21 and then flow inside the circular tubes 2 to fill all the circular tubes 2. The connecting vertical tubes 21 also support the multiple layers of circular tubes 2, making the overall structure of the multiple layers of circular tubes 2 relatively strong.
[0027] The outlet end of the liquid inlet pipe 13 is connected to the uppermost annular tube 2, and the outlet end of the mist inlet pipe 11 faces the middle position of the lowermost annular tube 2. The alkaline solution flowing into the liquid inlet pipe 13 can flow into the annular tube 2, and the outlet end of the mist inlet pipe 11 faces the side wall or inner bottom surface of the treatment tank 1, so that the waste liquid after the sulfuric acid mist reaction will not flow into the mist inlet pipe 11;
[0028] A plurality of spray heads 22 are also provided on the surface of the annular tube 2 . The plurality of spray heads 22 are evenly distributed around the annular tube 2 at equal intervals.

[0030] The inner wall of the processing tank 1 is also provided with multiple layers of support blocks 15. The spacing between each layer of support blocks 15 is consistent with the spacing between each layer of circular tubes 2. There are four to six support blocks 15 on each layer, which are evenly distributed around the inner wall of the processing tank 1 at equal intervals. The circular tubes 2 are clamped on the support blocks 15, and the support blocks 15 support the circular tubes 2.
[0031] Manual valves are provided on the mist inlet pipe 11, the liquid inlet pipe 13 and the liquid outlet pipe 14, which can be opened or closed manually according to work needs.
[0032] A fan 12 is also provided on the mist inlet pipe 11 , and the fan 12 rotates to suck the external sulfuric acid mist into the treatment tank 1 .
[0033] The inner bottom surface of the treatment tank 1 is spherical, and the liquid outlet pipe 14 is connected to the lowest position of the inner bottom surface of the treatment tank 1.
