Acid mist purification device applied in chrome plating process

Abstract

The invention discloses an acid mist purification device applied in the chrome plating process. The acid mist purification device comprises a purification box, and two partition plates are arranged in the purification box and divide the internal space of the purification box into a first chamber, a second chamber and a third chamber from left to right; the top of the first chamber is provided with a rotating atomization spray head, a breather pipe is arranged in the second chamber, the other end opening of the second chamber stretches into the position 7-18 cm under the solution level of an alkaline solution filled in the bottom of the second chamber, and the top of the third chamber is provided with a rotating atomization spray head. According to the acid mist purification device, acid gas in mixed gas can be sequentially purified by the chambers from left to right, a multiple purification action is achieved, and more thorough and complete purification can be achieved.

Description

technical field [0001] The invention belongs to the technical field of chrome plating, and in particular relates to an acid mist purification device in the chrome plating process. Background technique [0002] Chromium is a silvery-white metal with a sky blue color. It has strong passivation performance and is quickly passivated in the atmosphere. It shows the properties of noble metals, strong reflective ability and good wear resistance. Therefore, the chromium plating process has been adopted Widely used in industrial production. [0003] In the traditional chromium plating process, the electroplating solution is based on chromic acid and sulfuric acid is used as the activator. The ratio of the two is 100:1. The advantages of the process are: the plating solution is stable and easy to operate; The cathode efficiency is very low, resulting in the precipitation of a large amount of hydrogen and oxygen. When the gas escapes from the liquid surface, it contains a large amount...

[0003] In the traditional chromium plating process, the electroplating solution is based on chromic acid and sulfuric acid is used as the activator. The ratio of the two is 100:1. The advantages of the process are: the plating solution is stable and easy to operate; The efficiency of the cathode is very low, resulting in the precipitation of a large amount of hydrogen and oxygen. When the gas escapes from the liquid surface, it contains a large amount of chromic acid, which forms acid mist and enters the air, causing excessive air pollution.
