Description

Technical Field

[0001] The invention belongs to the field of acid mist processing, in particular to a liquefaction device for absorbing acid mist. Background Art

[0002] Acid mist usually refers to misty acidic substances. The particles of acid mist in the air are very small, smaller than those of water mist, and higher than the humidity of smoke. The particle size is 0.1-10μm. It is a substance between smoke and water mist and has strong corrosiveness. It includes acid mist formed by inorganic acids such as sulfuric acid, nitric acid, and hydrochloric acid, and organic acids such as formic acid, acetic acid, and propionic acid.

[0003] Acid mist is mainly produced in the acid-using process of chemical, electronic, metallurgical, electroplating, textile (chemical fiber), machinery manufacturing and other industries, such as acid production, pickling, electroplating, electrolysis, acid battery charging, etc. In addition, different acids are also used in some scientific research processes. Because these acid-using processes often use a mixture of multiple acids, the exhaust gas emitted is mostly a mixture of multiple acid mists.

[0004] The emission of acid mist will cause acid mist and acid gas to diffuse in the air of the workplace, and after being discharged into the atmosphere, it will cause acid deposition in the atmospheric environment. It not only endangers the health of workers and residents around the factory, corrodes factory equipment and precision instruments, causes losses in production and life, but also has adverse effects on the survival of crops and other animals and plants, and causes damage to buildings, cultural relics, etc.

[0005] In order to reduce the impact of acid mist, factories usually treat the acid mist;

[0006] After research, it was found that the existing liquefaction device for acid mist absorption has certain drawbacks when in use;

[0007] The existing liquefaction device for absorbing acid mist usually directly introduces the acid mist into the liquefaction equipment, reacts it with alkaline water, thereby causing acid-base neutralization. When in use, in order to improve efficiency and increase its suction, its movement speed is relatively fast, which is prone to uneven acid-base neutralization and requires secondary treatment. Therefore, it requires multiple sets of equipment to cooperate, occupies a relatively large space, and requires very high costs, which does not meet people's usage requirements. For this reason, people have invented a liquefaction device for absorbing acid mist. Summary of the invention

[0008] In order to overcome the shortcomings of the prior art, the embodiment of the present application provides a liquefaction device for acid mist absorption of the present invention, which records a liquid supply pipeline, a liquefaction component and an acid mist adding component for adding alkali solution. When in use, the acid mist adding component guides the acid mist into the interior of the spiral guide for rotational motion, thereby extending the movement path of the acid mist, so that the acid mist and the alkali solution can be in more sufficient contact, thereby improving the treatment effect of the acid mist, and has a good prospect of use.
