Air purifying apparatus

Abstract

The invention relates to an air purifying apparatus, which comprises: a shell (1), wherein a wind channel is arranged inside the shell; adsorption modules arranged in the wind channel and made of at least a material selected from calcium chloride and calcium oxide; and a suction component (3) arranged in the shell (1) and used for sucking outside air into the shell (1) and discharging after the air passes through the adsorption modules. According to the present invention, the air purifying apparatus can remove moisture or corrosive gas from air to purify the air so as to reduce the problem ofthe rusting of metal parts during storage based on the corrosion source weakening, such that the hidden danger of engine trial failure can be reduced, the use safety of engines can be improved, and the waste of parts can be reduced if the metal parts are used for engine assembly; and the air purifying apparatus has characteristics of simple structure, energy saving, emission reduction and low cost.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of metal parts, in particular to an air purification device. Background technique [0002] With the continuous deepening of production such as assembly, assembly, and test run, the components of aero-engines are prone to corrosion problems of varying degrees. Especially if the manufacturer is located in the coastal area, the climate is mild and humid, depending on the landform and the main airflow direction, the air environment is easily polluted by sea salt aerosol (mainly chloride), which is a typical marine atmospheric environment. Engine components stored in this environment are susceptible to corrosion due to the action of moisture film and corrosive atmosphere. [0003] When the engine parts are stored in the warehouse of the factory area, for general conditions, the temperature of the warehouse is ≤35°C, the relative humidity is ≤70%RH, and the content of chloride ions in the air exc...

AI Technical Summary

Problems solved by technology

[0003] When the engine parts are stored in the warehouse of the factory area, for general conditions, the temperature of the warehouse is ≤35°C, the relative humidity is ≤70%RH, and the content of chloride ions in the air exceeds 40 times the normal value, and some parts are easily damaged during storage. Corrosion occurs, so the problem of anti-corrosion of parts needs to be solved urgently

[0004] At present, although a storage room for easily-corroded products has been set up in the factory area, it is used to store the easily-corroded parts of the engine separately. The content of chloride ions has not been effectively controlled, and it is difficult to meet the strict requirements of anti-corrosion, so parts may still be rusted

[0005] Once the corroded metal parts are assembled on the engine during the engine production process, there will be hidden dangers of engine test failure, which will reduce the safety of the engine.

In addition, the corrosion of metal parts will also cause waste of parts and increase production costs.
