Description
Technical field
The utility model belongs to the energy recovery mechanical skill, relates to the device that a kind of thermal oil absorbs yellow phosphorus burning heat energy.
Background technology
Phosphoric acid and phosphoric acid salt are the important component parts of chemical industry.The working method of phosphoric acid is divided into two kinds of thermal phosphoric acid and phosphoric acid by wet processes.Because thermal phosphoric acid has advantages such as product concentration height, impurity are few, has been widely used in phosphorous chemical industry enterprise.The technological process of production master operation of thermal phosphoric acid is that yellow phosphorus fusion, yellow phosphorus burning and aquation absorb.The method of Chinese patent CN201010127125.2 directly preparing food-grade high-purity phosphoric acid from yellow phosphorus; Be that liquid phosphorus is under the certain waterhead condition of phosphorus scale tank; In combustion tower bottom phosphorus supply constantly; Liquid phosphorus is burnt under the effect of air oxygen supply, and the Vanadium Pentoxide in FLAKES gas that burning produces causes negative pressure 10000-15000Pa to get into main absorption tower from cat head by the afterbody blower fan.The 1 ton of yellow phosphorus that burns will produce the heat of 24335KJ, and pyritous phosphorus steam and polymkeric substance thereof have extremely strong corrodibility with destructive to production units such as combustion tower and interchanger.Produce in order to prevent this corrosion and to destroy, in the existing technology, this heat is all taken out of with a large amount of dilute phosphoric acids or water coolant usually, is reclaimed phosphoric acid and is purified qualified discharge by cooling tower or other acid fog absorption tower through heat exchange.Through retrieval, the method that reclaims yellow phosphorus burning heat energy also has:
Phosphatic one-step technology of Chinese patent CN200710049440.6 phosphorus production and device.The high temperature Vanadium Pentoxide in FLAKES gas (1000-1600 degree) that yellow phosphorus burning is produced in this invention sends into waste heat boiler and water carries out heat exchange, generates HP steam, flows to phosphorus-melting groove and external application life through steam conveying pipe.One ton of yellow phosphorus of every burning can produce the water vapour 6.5-7.0 ton of pressure position 0.4-0.8Mpa, and energy recovery and utilising efficiency reach 90%, can Vanadium Pentoxide in FLAKES gas be cooled to 200-450 ℃.Though this utility model can reduce the temperature of Vanadium Pentoxide in FLAKES gas and reach certain heat utilization efficiency, utilize waste heat to generate the use that boiler and water coolant are set that HP steam increased, increased production cost.
Chinese patent CN01143443.0 yellow phosphorus burning energy recovery and use device and thermal phosphoric acid production system.The sealed wall combustion chamber that this invention adopts membrane wall to form replaces the water jacket combustion chamber of former technology.Membrane wall is the integral part of conventional waste heat boiler, as upcast.The steam guiding tube that boiler is furnished with drum, downtake, annular lower collecting box and upper header in addition and links to each other with drum.Adopt plasma-coated conduct to prevent corrosion resistant coating, thereby phosphorus corrosive medium and combustion tower metal wall are separated, avoid the high temperature corrosion effect, thereby allow the wall temperature of interchanger to reach 200-500 ℃.The innovative point of its UTILIZATION OF VESIDUAL HEAT IN is that the part steam that reclaims is used through the phosphorus-melting groove in steam-pipe supply self technical process, and generation higher-grade high temperature, HP steam are produced use altogether, and the waste heat recovery rate can reach more than 60%.Though adopt membrane type water chiller, plasma-coated in this invention; But still use water coolant as heat-transfer medium; Because in the time of 100 ℃, the thermal conductivity of water vapour is 0.0237W/m. ℃, and ℃; And the thermal conductivity of Mobiltherm605# thermal oil in the time of 100 ℃ is 0.127W/ (m. ℃), is 5.35 times of water vapour.Can know that the heat-conducting effect of water is far away not as good as thermal oil.In addition, water is as heat-conducting medium, and temperature is high more, and the saturated vapor pressure of water vapour is high more, and is higher to the requirement of equipment.Moreover because waste heat boiler links to each other with combustion phosphorus equipment, and it is equivalent to a high-duty boiler, and potential safety hazard is bigger, the safety check expense is higher.
Thermal oil has the performance of heat resistanceheat resistant cracking and chemical oxidation, and heat transfer efficiency is good, rapid heat dissipation, and thermostability is fine.Be widely used in fields such as exhaust gases of internal combustion engines recovery, fume afterheat generating, semi-conductor generating at present.Its utilization is not seen in the phosphorous chemical industry field.
