Description

Technical Field

[0001] The utility model belongs to the field of separation of acidic component gas or steam, and in particular relates to an acid mist collecting device which can be used for panel installation. Background Art

[0002] Acid mist usually refers to misty acidic substances. The particles of acid mist in the air are very small, smaller than water mist particles, higher than smoke humidity, with a particle size of 0.1 to 10 μm. It is a substance between smoke and water mist and has strong corrosiveness.

[0003] As pre-treatment equipment for analytical instruments such as atomic absorption and liquid chromatography, microwave digestion and acid removal instruments will produce a large amount of acid mist during use.

[0004] If the instrument is not equipped with an acid mist collection device, the acid mist cannot be extracted or collected in time and will permeate the laboratory, which will not only corrode equipment and objects, but also affect the health of experimental operators.

[0005] Acid mist collection devices take corrosion resistance into consideration, and most are designed with Teflon sprayed on the surface of metal parts.

[0006] In order to protect the environment and reduce costs, the use of Teflon needs to be reduced, and exhaust ducts are often designed, and acid mist collection devices are installed in areas where acid mist is concentrated.

[0007] At present, the acid mist collection devices in pre-treatment instruments are mostly placed in the laboratory or in the visible area of ​​the process.

[0008] The utility model patent with the authorization announcement date of 2021.07.09 and the authorization announcement number of CN213643659U discloses "an acid mist collection device", including a circulating water tank, a collection tank and a terminal filter box. The upper end of the circulating water tank is fixedly connected to the collection tank, and an air inlet is provided at the lower end of the outer side of the collection tank. The top of the collection tank is fixedly connected to a collection hood, one end of the gas collecting pipe is fixedly connected to an air path pipeline, and the other end of the air path pipeline is fixedly connected to a terminal filter box. The side of the circulating water tank is fixedly connected to a circulating water pipe, and one end of the circulating water pipe is fixedly connected to a swirl plate spray layer. The interior of the collection tank is provided with a hollow filler, and the upper end of the interior of the collection tank is provided with a swirl demisting layer. The interior of the terminal filter box is provided with an activated carbon adsorption layer and a molecular sieve. The acid mist collection device, through the coordinated setting of the circulating water pipe and the swirl plate spray layer, plays the role of collecting acid mist, and cooperates with the swirl demisting layer and the hollow filler to achieve the purpose of quickly collecting acid mist.

[0009] However, in the above technical solution, the acid mist collection device is a self-contained system, which requires a large space and cannot be integrated with the existing pre-treatment equipment. It is also not convenient to collect the acid mist in a centralized manner at the acid mist generation point of the pre-treatment equipment.

[0010] With the rapid development of the domestic processing and manufacturing industry, people's aesthetic concepts are also improving, and higher requirements are put forward for the appearance design of the instrument. Therefore, when designing the acid mist collection device, not only the acid discharge effect and corrosion resistance should be considered, but also the aesthetics of the acid mist collection device installed on the instrument should be considered.
