Description
Technical field
The invention belongs to technical field of inorganic chemical industry, relate to a kind of rectangular 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 thermal phosphoric acid and phosphoric acid by wet process two kinds.It is raw material that thermal phosphoric acid refers to Rock Phosphate (72Min BPL), is first processed into element phosphor, then with the phosphoric acid that element phosphor processes; Phosphoric acid by wet process refers to Rock Phosphate (72Min BPL) and mineral acid for raw material, the phosphoric acid directly processed.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 the perfect combustion method absorbing phosphoric acid processed after directly burning with phosphorous furnace gas with water; Method two is by phosphorous furnace gas and appropriate air mixed, make phosphorus steam and phosphine gas oxidized, then gas oxidation products Vanadium Pentoxide in FLAKES dilute phosphoric acid is absorbed and obtained phosphoric acid; Method three is that the phosphorus in phosphorous furnace gas is condensed into liquid phosphorus, generates Vanadium Pentoxide in FLAKES with air combustion, then uses water (or acid) to absorb the liquid phosphorus combustion method of obtained phosphoric acid.At present, the liquid phosphorus combustion method that adopts produces thermal phosphoric acid more.In phosphorous acid production by BEP, existing phosphorus supply method is high-order phosphorus supply method.Namely, after the molten phosphorus in phosphorus-melting groove melting being transported to header tank with high-pressure pump or pressurized air, roasting kiln epimere is flowed into high pressure spraying, spraying and burning.The advantage of this method is: melt phosphorus through spraying, sufficient combustion; But its shortcoming is: owing to adopting power machine conveying, one is the input increasing equipment funds; Two is increase energy consumption; Three is that delivery safety performance requriements is high.In phosphorous acid production by BEP, the quality of the combustion position of yellow phosphorus in roasting kiln, to the quality of phosphoric acid product and the yield important of phosphorus.Yellow phosphorus burning is insufficient, the problem such as may cause that the color of phosphoric acid product is partially yellow, readily oxidizable substance exceeds standard, chimney emits tobacco, acid glue at the bottom of roasting kiln is too much.In currently available technology, the liquid phosphorus combustion method that adopts produces thermal phosphoric acid more.Namely, after the molten phosphorus in phosphorus-melting groove melting being transported to header tank with high-pressure pump or pressurized air, roasting kiln burning is flowed into high pressure spraying.Though yellow phosphorus enters roasting kiln in the mode of high pressure spraying in this method, better dispersed, enter the yellow phosphorus of roasting kiln still in droplet-like, itself and air are difficult to reach the state fully contacted, and then have impact on the combustion efficacy of yellow phosphorus to a certain extent.Given this, we are from phosphoric acid production reality for many years, and a kind of rectangular pipe yellow phosphorus gasification combustion furnace has been invented in research, through reading up the literature, not having and using this rectangular pipe yellow phosphorus gasification combustion furnace.Adopt apparatus of the present invention that yellow phosphorus is gasified and fully mix afterfire with air, avoid in traditional combustion mode, the disadvantageous effect that yellow phosphorus burning does not thoroughly bring, create 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 safe phosphorus supply device of phosphorous acid production by BEP, employing is ironed and is melted raw material yellow phosphorus at low level: through waterhead safe transport in phosphorus-melting groove, stove combustion is entered by the bottom of roasting kiln, avoid in conventional production lines and melt yellow phosphorus with high-pressure pump or pressurized air be transported to header tank by being in ironing under high-risk status, and then the operation link of this danger of burning through high pressure spraying.And reduction energy consumption, minimizing facility investment, stay-in-grade effect can be reached.Phosphorous acid production by BEP safe phosphorus supply device is practical, better economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of yellow phosphorus that can make and gasifies and fully mix the rectangular pipe yellow phosphorus gasification combustion furnace of afterfire with air.
To achieve these goals, present invention employs following technical scheme:
A kind of rectangular pipe yellow phosphorus gasification combustion furnace, comprise roasting kiln, described roasting kiln is connected with phosphorus-melting groove, it is characterized in that: be provided with vapor lamp, hook and bracing frame in described roasting kiln.
Above-described vapor lamp formed rectangle along roasting kiln inwall around one week, one end of vapor lamp extends in the middle of bottom roasting kiln obliquely from rectangular angular, and arrange nozzle at vapor lamp tail end, the sleeve pipe that the other end is arranged 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 nozzle is arranged upwards.
Above-described vapor lamp and outer nozzle wall are provided with high temperature resistant graphite linings.
Above-described vapor lamp and nozzle are acidproof, high temperature material, and described acidproof, high temperature material are stainless steel.
Beneficial effect of the present invention:
The heat that the present invention utilizes yellow phosphorus burning self to produce, enter roasting kiln after liquid phosphor in roasting kiln in rectangle vapor lamp is gasified fully to mix with air, thus reach the state of perfect combustion, ensure the quality of phosphoric acid product and the yield of phosphorus, make it have good economic benefit and social benefit.
