Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection purification treatment devices, in particular to an environmental protection purification treatment device containing chromic acid mist. Background Art

[0002] Chromic acid mist is liquid droplets formed by the volatilization of chromic acid in the air. It is commonly found in the air around the plating tank during electroplating operations. When the mass concentration in the air reaches 0.1 mg / m3, long-term contact can cause nasal septum perforation. If the concentration of chromic acid mist is too high, nasal septum perforation can occur after months of contact. In addition, it can also cause pharyngitis, pneumonia and allergic asthma. Chromic acid mist is a skin allergen, causing allergic dermatitis or eczema. The characteristics of eczema are mostly small pieces, coin-shaped, mainly subacute, with erythema, infiltration, exudation, desquamation, long course, and long-term non-healing. It enters through breathing and has irritating and corrosive effects on the respiratory tract, causing rhinitis, pharyngitis, bronchitis, and in severe cases, erosion of the nasal septum or even perforation. When the concentration of chromic acid mist is lower than the national health standard, it can still cause varying degrees of damage to the contactor.
