Description
Technical field
The utility model belongs to technical field of inorganic chemical industry, relates to a kind of coil pipe yellow phosphorus gasification combustion furnace.
Background technology
Phosphoric acid is the important component part of chemical industry, is important basic chemical industry raw material.The production method of phosphoric acid is divided into two kinds of thermal phosphoric acid and phosphoric acid by wet processes.Thermal phosphoric acid refers to taking Rock Phosphate (72Min BPL) as raw material, is first processed into element phosphor, then the phosphoric acid processing with element phosphor; Phosphoric acid by wet process refers to taking Rock Phosphate (72Min BPL) and mineral acid as raw material, the phosphoric acid directly processing.The thick product of phosphoric acid by wet process is impure more, mainly for the production of fertilizer; Thermal phosphoric acid but has the advantages such as product concentration is high, impurity is few, can be used for manufacturing food and PHOSPHORIC ACID TECH.GRADE product salt.The production method of thermal phosphoric acid has three kinds: method one is with the directly perfect combustion method of the rear water absorption of burning phosphoric acid processed of phosphorous furnace gas; Method two is by phosphorous furnace gas and appropriate air mixed, makes phosphorus steam and phosphine gas oxidized, then gas oxidation products Vanadium Pentoxide in FLAKES is made to phosphoric acid with dilute phosphoric acid absorption; Method three is that the phosphorus in phosphorous furnace gas is condensed into liquid phosphorus, generates Vanadium Pentoxide in FLAKES with air combustion, and then water (or acid) absorbs the liquid phosphorus combustion method that makes phosphoric acid.At present, adopt liquid phosphorus combustion method to produce thermal phosphoric acid more.In thermal phosphoric acid is produced, existing phosphorus supply method is high-order phosphorus supply method.With high-pressure pump or pressurized air, the molten phosphorus in phosphorus-melting groove melting is transported to after header tank, flows into roasting kiln epimere, spraying and burning with high pressure spraying.The advantage of this method is: molten phosphorus is through sprinkling, sufficient combustion; But its shortcoming is: owing to adopting power machine to carry, and the one, the input of increase equipment funds; The 2nd, strengthen energy consumption; The 3rd, delivery safety performance requriements is high.In thermal phosphoric acid is produced, the quality of the combustion position of yellow phosphorus in roasting kiln, the yield important of the quality to phosphoric acid product and phosphorus.The problems such as yellow phosphorus burning is insufficient may cause that the color of phosphoric acid product is partially yellow, readily oxidizable substance exceeds standard, chimney emits tobacco, acid glue is too much at the bottom of roasting kiln.In currently available technology, adopt liquid phosphorus combustion method to produce thermal phosphoric acid more.With high-pressure pump or pressurized air, the molten phosphorus in phosphorus-melting groove melting is transported to after header tank, flows into roasting kiln burning with high pressure spraying.Though yellow phosphorus enters roasting kiln in the mode of high pressure spraying in this method, better dispersed, the yellow phosphorus that enters roasting kiln is still droplet-like, and it is difficult to reach with air the state fully contacting, and then has affected to a certain extent the combustion efficacy of yellow phosphorus.Given this, we are from phosphoric acid production reality for many years, and a kind of coil pipe yellow phosphorus gasification combustion furnace has been invented in research, through reading up the literature, do not have this coil pipe yellow phosphorus gasification combustion furnace of use.Adopt apparatus of the present invention to make yellow phosphorus gasification fully mix afterfire with air, avoided in traditional combustion mode, the disadvantageous effect that yellow phosphorus burning does not thoroughly bring, creates good economic benefit and social benefit.
Chinese patent: number of patent application 201010127143.0, notification number CN101804975A, day for announcing 2010.8.18, this this disclosure of the invention thermal phosphoric acid produce safe phosphorus supply device, employing is ironed and is melted raw material yellow phosphorus at low level: in phosphorus-melting groove through waterhead safe transport, enter in stove and burn by the bottom of roasting kiln, avoid with high-pressure pump or pressurized air, ironing under high-risk status being melted to yellow phosphorus in conventional production lines and be transported to header tank, and then through high pressure spraying this dangerous operation link that burns.And can reach reduction energy consumption, minimizing facility investment, stay-in-grade effect.Thermal phosphoric acid is produced with safe phosphorus supply device practical, better economic benefit.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can makes yellow phosphorus gasification and fully mix the coil pipe yellow phosphorus gasification combustion furnace of afterfire with air.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of coil pipe yellow phosphorus gasification combustion furnace, comprises roasting kiln, and roasting kiln is connected with phosphorus-melting groove, it is characterized in that: in described roasting kiln, be provided with circular vapor lamp, hook and bracing frame.
Above-described vapor lamp is along roasting kiln inwall around a circle, and one end vapor lamp tiltedly extends downward in the middle of roasting kiln bottom, and is provided with nozzle at vapor lamp tail end, and the sleeve pipe that the other end arranges by the stove chuck of roasting kiln is connected with phosphorus-melting groove.
Above-described vapor lamp is fixedly mounted on the hook of roasting kiln inwall and the bracing frame of furnace hearth plate.
Above-described circular vapor lamp arranges 1-3 circle.
Above-described nozzle setting upwards.
Above-described vapor lamp and nozzle outer wall are provided with high temperature resistant graphite linings.
