Dew point dehumidification unit for quality improvement and consumption reduction of phosphorus pentoxide production

Abstract

The invention discloses a dew point dehumidification unit for quality improvement and consumption reduction of phosphorus pentoxide production. The technological process of the dew point dehumidification unit comprises the following step of primary filtration treatment. Fresh air is subjected to filtration treatment with a primary filter. The dew point dehumidification unit for quality improvementand consumption reduction of phosphorus pentoxide production is used for an air dehydration drying treatment technology, because about 780KW.H of electric energy is consumed for producing one ton ofphosphorus pentoxide, and the direct production cost is about 400 RMB, it is achieved that electricity consumed for air drying treatment is reduced, and the production cost of phosphorus pentoxide isreduced; because a heater is arranged at the tail end of an exhaust fan, the heater can carry out heating treatment on the air subjected to drying dehydration with a rotary dehumidifier, preheating isimplemented on the air subjected to drying dehydration with the rotary dehumidifier, the air subjected to drying dehydration with the rotary dehumidifier keeps stable in temperature, the air enters an oxidization combustion furnace, the oxidization combustion reaction between the air and yellow phosphorus which melts after being heated is complete and more stable, and the quality of prepared phosphorus pentoxide is improved.

Description

technical field [0001] The invention relates to the technical field of phosphorus pentoxide production, in particular to a dew point dehumidification unit for improving quality and reducing consumption in the production of phosphorus pentoxide. Background technique [0002] Phosphorus pentoxide is used as a desiccant for gases and liquids, a dehydrating agent for organic synthesis, an antistatic agent for polyester resin, a refined preparation for medicines and sugar, and is the matrix for preparing high-purity phosphoric acid, phosphate, phosphide and phosphoric acid ester. Raw material, it can also be used in the manufacture of phosphorus pentoxide sol and H-type aerosol, used in the manufacture of optical glass, UV-transparent glass, heat-insulating glass, glass-ceramic and opalescent glass, etc., to improve the dispersion of glass coefficient and the ability to pass through ultraviolet rays. The production process of phosphorus pentoxide is an oxidation method. After hea...

Problems solved by technology

[0003] The dew point dehumidification unit used in the production of phosphorus pentoxide to improve quality and reduce consumption is the unit that dehydrates and dries air in the production process of phosphorus pentoxide. More than 85% of the energy consumption leads to an increase in product production costs. At the same time, the traditional phosphorus pentoxide production lacks air pretreatment measures in the air compression drying process, which affects product quality.
