Description
Technical field:
The utility model belongs to the air cleaning facility technical field, relates to a kind of device of air cleaning, especially uses the device of phosphoric acid adsorption and dehumidification and dedusting air cleaning.
Technical background:
Thermal phosphoric acid is that yellow phosphorus burns in air and produces P
2O
5, absorb through hydration again and process.Phosphoric acid is middle strong acid, has very strong water imbibition.The P that burning is produced
2O
5Very easily, under the different water yields and reaction condition, can form mixtures such as metaphosphoric acid, pyrophosphoric acid and tripolyphosphate, also reduce the quality of product when having increased the phosphorus consumption with hydrate; The used air that burns plays a part very important to phosphoric acid production; Often contain mixtures such as moisture, dust and other foreign matters in the air; This type of material does not just directly use in phosphoric acid production as if treated; The increase of equipment corrosion, the reduction of raw material availability and the problems such as reduction of product quality will be caused, the production requirement of high-purity phosphoric acid can't be satisfied especially.In order to prevent the generation of phosphorus polymer, reduce the phosphorus consumption, improve utilization ratio of raw materials and take off H with production electron level, food grade phosphoric acid and dearsenification phosphoric acid
2The S operation use the gas requirement, all need dehumidify and udst separation is handled to air.Therefore, the dehumidifying of air and dedusting are the problems that needs solution during phosphorous chemical industry is produced.
In order to prevent phosphoric acid polymerization thing that thermal phosphoric acid forms in producing to corrosion on Equipment, the method that adopted of phosphorous chemical industry industry mainly contains three kinds at present: one, use dry air and yellow phosphorus burning.During domestic thermal phosphoric acid was produced, air dry technology commonly used was to dewater with the concentrated sulfuric acid, but the regeneration of the drier concentrated sulfuric acid and introducing will increase the cost of air cleaning; Two, control air humidity is taked to control interior air of unit interval and is brought moisture and the P that reacts generation in the tower into
2O
5Mol ratio is in a certain scope, and making and forming main component in the tower is the conjunctiva thing of metaphosphoric acid, protects the combustion tower inwall not to be corroded through the conjunctiva thing.As: Chinese patent CN200810058781.4, a kind of method of utilizing the id reaction product to carry out high-temperature anticorrosion adopts normal air for feeding the air of combustion tower, and control combustion tower wall surface temperature is lower than 490 ℃, moisture and product P in the tower
2O
5Mol ratio between 0.01～0.8, that combustion tower can form is stable, structure and the certain ultra phosphoric acid conjunctiva thing of composition, thereby reaches the effect of equipment anticorrosion.Though the method can reach the corrosion-resistant effect through control air humidity, the formation of phosphoric acid polymer has increased the phosphorus consumption virtually, has reduced utilization ratio of raw materials, but also can not reach the air cleaning requirement of producing electron-level phosphoric acid and food grade phosphoric acid; Three, use normal air and yellow phosphorus burning; Chinese patent CN0114344.0; Phosphorus combustion heat recovery and utilization device and its thermal phosphoric acid production system; This inventive method has adopted the plasma spraying aseptic technic, therefore in the technical process of yellow phosphorus burning, only uses normal air, need not use dry air.The method not only increases the phosphorus consumption, nor can reach the air cleaning requirement of producing electron-level phosphoric acid and food grade phosphoric acid.
At present, be used for industry air dewetting, purified treatment such as building materials, chemical industry, HVAC, air-conditioning, weaving, the dehumanization method of use mainly contains: freeze drying, compression dehumidifying, solid absorption dehumidifying, liquid adsorption dehumidifying etc.Dehydrating unit mainly contains: rotary-type dehumidifier, packed tower dehumidification equipment, heat pump drying device, compressed air drier etc.Like Chinese patent 97222358.4 heat pump drying devices, be between device case evaporimeter and inner walls, to set up a by-pass, it makes, and refrigerating capacity is complementary in the humid air that gets in the evaporimeter and the equipment, with the raising effect on moisture extraction; Rotary dehumidifier like Chinese patent CN200810000968.9; Be to utilize instantaneous high heat to make a large amount of rapidly evaporations of moisture contained in the hygroscopic agent; In the local environment space, produce highdensity supersaturation water steam; Condense voluntarily under the effect that perturbation, dust and the solid of air shield again of said supersaturation water steam, and need not to be provided with in addition condenser system, thereby cut down the consumption of energy steam; Like the compressed air drier of Chinese patent CN200510115596.0, be to utilize air blast that the air in the atmosphere is flow in the regenerating tank, during heating, because the 80 degree heats of compression Celsius of air blast are arranged, so the heater heat that consumes is less; During cooling, do not use compressed air, but directly circulate, when having kept the air aridity, realize cooling, thereby obtain energy-conservation effect with atmospheric air.
Through document retrieval, in the thermal phosphoric acid production with the purifying air of required dehumidifying of other industry and dedusting in, all do not have use phosphoric acid as adsorbent to the air device with the udst separation processing that dehumidifies.We set out in conjunction with phosphoric acid production is actual according to the principle of air dewetting and the air dehumidifier principle of every profession and trade, and the device of this usefulness phosphoric acid adsorption and dehumidification and dedusting air cleaning has been invented in research.
In sum, for the phosphorus polymer that prevents to form in the thermal phosphoric acid production in the method that corrosion on Equipment adopted, control air moisture and product P
2O
5Mol ratio forms ultra phosphoric acid conjunctiva thing in a certain scope, can increase the phosphorus consumption, has improved production cost; Adopt other air dewettings and dust arrester, the air cleaning processing cost is higher.The phosphoric acid adsorption and dehumidification of the utility model and the device of dedusting air cleaning can obtain the higher degree air, improve thermal phosphoric acid utilization ratio of raw materials, product yield, the quality of product and the antiseptic effect of equipment, reduce the purification cost of air dewetting and dedusting.
