Description

Technical Field

[0001] The utility model belongs to the technical field of condensers, and in particular relates to a phosphorus trichloride evaporation condenser. Background Art

[0002] Phosphorus trichloride is a colorless, clear, fuming liquid with a melting point of -112°C, a boiling point of 75.5°C, and a vapor pressure of 13.33 kPa (21°C). It is soluble in ether, benzene, chloroform, carbon disulfide, and carbon tetrachloride. It can absorb moisture and hydrolyze into metaphosphorous acid and hydrogen chloride when exposed to air, and produce white smoke and deteriorate. It reacts with oxygen to form phosphorus oxychloride and with chlorine to form phosphorus pentachloride. It will catch fire when in contact with organic matter. It is flammable. It is easy to irritate mucous membranes, corrosive, and toxic. Phosphorus trichloride can hydrolyze into phosphorous acid and hydrogen chloride in humid air, and produce white smoke and deteriorate. It must be stored in a sealed container.

[0003] Phosphorus trichloride produces a large amount of gaseous phosphorus trichloride in production. The principle of the phosphorus trichloride condenser is to use cooling water or cold air to cool the gaseous phosphorus trichloride to a relatively low temperature so that it condenses into liquid. The condensed liquid phosphorus trichloride can flow out through a pipeline for subsequent treatment or collection. However, during the condensation process of the phosphorus trichloride evaporative condenser in the prior art, impurities (mainly phosphorus trichloride oxide, thionyl chloride, phosphoric acid and impurity metal ions) are carried by the inside. When the evaporative condenser is used for a long time, impurities will be continuously attached to the filter element. Therefore, it is necessary to regularly clean or replace the filter element, but the existing filter mechanism is troublesome to replace and inconvenient to disassemble. Utility Model Content
