Problems solved by technology
The advantage of this method is that the molten phosphorus is fully burned after being sprayed; but its disadvantages are: due to the use of power machinery for transportation, firstly, the investment in equipment capital is increased; secondly, energy consumption is increased; thirdly, the safety performance of transportation is required to be high
In this method, although the yellow phosphorus enters the combustion furnace by high-pressure injection, the dispersibility is good, but the yellow phosphorus entering the combustion furnace is still in the form of droplets, and it is difficult to reach a state of full contact with the air, which affects to a certain extent. Burning effect of yellow phosphorus

The invention discloses a yellow phosphorus gasified combustion device which is full in combustion and high in utilization rate and can prevent deposition of acid gel. The yellow phosphorus gasified combustion device comprises: a furnace body, internally forming a combustion chamber, wherein a flame retardant coating is arranged in the side wall of the furnace body, the side wall of the furnace body is sleeved with a first heat exchange jacket, the first heat exchange jacket is provided with a water inlet and a water outlet, and a gas outlet pipe is arranged at the upper part of the side wallof the furnace body; a round fixing base, arranged on a base of the furnace body; an annular rotating table, rotatably arranged at the upper end of the fixing base along the circumference; a gas-liquid mixing device for mixing liquid-state yellow phosphorus in a phosphorus-melting groove and a certain amount of air; a liquid nozzle, fixedly arranged in the center of the upper end of the annular rotating table, wherein the nozzle opening direction of the liquid nozzle is upward obliquely, and an inlet of the liquid nozzle is communicated with an outlet of the gas-liquid mixing device through aliquid inlet pipe; a plurality of air nozzles, uniformly arranged around the liquid nozzle and provided with upward nozzle openings, wherein the air nozzles are fixed to the fixing base.
Description
technical field [0001] The invention relates to the field of phosphorus chemical industry, in particular to a yellow phosphorus gasification combustion device. Background technique [0002] Phosphoric acid is an important part of the chemical industry and an important basic chemical raw material. The production methods of phosphoric acid are divided into thermal phosphoric acid and wet phosphoric acid. Thermal phosphoric acid refers to phosphoric acid that uses phosphate rock as raw material, firstly processes it into elemental phosphorus, and then processes it with elemental phosphorus; wet-process phosphoric acid refers to phosphoric acid that is directly processed from phosphate rock and inorganic acid as raw materials. The crude product of wet-process phosphoric acid contains more impurities and is mainly used to produce fertilizers; while thermal phosphoric acid has the advantages of high product concentration and less impurities, it can be used to manufacture food and...
