Description

Technical Field

[0001] The utility model relates to the technical field of gas conveying equipment, in particular to a purge mechanism of corrosive gas conveying equipment. Background Art

[0002] In a narrow sense, gas corrosion refers to the corrosion that occurs when the metal reacts only with the gaseous corrosive agent without any liquid phase on the metal surface, that is, the corrosion process that occurs when there is no moisture condensing on the surface of the metal material. Gas corrosion generally refers to corrosion at high temperatures. Gas corrosion is one of the most common and important forms of chemical corrosion. The main factors affecting the rate of gas corrosion are the chemical composition of the metal material, the composition of the medium, the movement speed of the medium, pre-deformation, surface state and temperature. The main methods to prevent gas corrosion are: using heat-stable alloys, controlling the composition of the gas medium, coating or plating on the surface of the metal material, using conveying equipment when conveying corrosive gases, and using a purge mechanism to clean the conveying equipment after use.

[0003] The purge mechanism of the corrosive gas conveying equipment in the prior art, when actually used, the corrosive gas and pollutants remaining inside the conveying equipment will be discharged from the air outlet pipe of the conveying equipment, and direct discharge is likely to cause pollution to the surrounding environment, so a filter plate is required for filtering, and the filter plate is usually installed inside the filter box by bolts, etc. After long-term use, the bolts are prone to corrosion, making it difficult to replace the filter plate, resulting in inconvenience during use. Therefore, we propose a purge mechanism for corrosive gas conveying equipment to solve the above-mentioned problems. Utility Model Content
