Wind-moving and energy-saving neutralization reactor in ammonium phosphate production system

Abstract

The invention relates to a wind-moving and energy-saving neutralization reactor in an ammonium phosphate production system. The wind-moving and energy-saving neutralization reactor comprises a cylinder body, a phosphoric acid inlet pipe, an ammonia inlet pipe, a slurry overflow port pipe and a steam exit pipe, wherein the bottom of the cylinder body is provided with at least one phosphoric acid inlet pipe extending into the cylinder body and at least one ammonia inlet pipe extending into the cylinder body; pipe orifices extended into the cylinder body of the phosphoric acid inlet pipe and the ammonia inlet pipe have a gap and are not parallel and in different directions; the upper portion of the cylinder body is provided with the slurry overflow port pipe; and the top of the cylinder body is provided with the steam exit pipe. By employing oppositely arranged pipe orifices of the phosphoric acid inlet pipe and the ammonia inlet pipe to extend into a mixing pipe for feeding materials, reaction can be fully carried out; generated slurry escapes from holes on the mixing pipe and are finally exhausted through the slurry overflow port pipe; and the raw materials perform wind-moving neutralization reaction in the mixing pipe; so that material-feeding pressure and chemical reaction heat energy can be used effectively; and the neutralization reactor has the advantages of simple structure, short flow path, high production power and the like, is in no need of power equipment, saves production cost, and reacts adequately.

Description

technical field [0001] The invention relates to the field of ammonium phosphate production, in particular to an orbiting energy-saving neutralization reactor for the neutralization reaction of phosphoric acid and ammonia gas. Background technique [0002] In the production process of ammonium phosphate series, phosphoric acid and ammonia gas are neutralized to produce dilute ammonium phosphate slurry. The existing neutralization reaction equipment is usually agitated neutralization tank, tubular reactor, loop reactor, etc. The reaction time is short, the reaction heat cannot be fully utilized, the ammonia loss rate is high, the effluent is polluted, and the equipment is easy to scale. At the same time, it must be supplemented by power equipment, which wastes energy, increases energy consumption and production costs, and affects production capacity.
