Description
Technical field
The present invention relates to a kind of hypergravity ammonia removal device and application method, is a kind of ammonia decontamination processing unit, belongs to work
Industry handles the technical field of ammonia equipment.
Background technology
Ammonia is a kind of hydronitrogen, is toxic gas that is a kind of colourless but having intense irritation smell, it is easily molten
Yu Shui, 1 volume of water can dissolve 700 volume ammonias, and the hydration of chemical reaction generation one occurs for Yi Yushui when ammonia is dissolved in water
Ammonia.The boiling point of ammonia is -33.5 degrees Celsius, easily liquefaction, industrially usually uses this characteristic, refrigeration working medium is used as using ammonia.Ammonia
Due to containing nitrogen in gas, soda ash, nitric acid, ammonium salt and chemical fertilizer processed etc. are widely used in.
The ammonia explosion limit is 15.7~27.4%, and its fire risk belongs to 2 articles of Class B.Therefore, ammonia and sky
Gas or oxygen mix can form explosive mixture.Ammonia can attack moist skin, mucous membrane and eyes, can cause deep coughs, branch
Tracheospasm, acute pulmonary edema, or even blindness and death by suffocation can be caused.Current ammonia decontamination technology both domestic and external mainly has:
Chemical absorbing, catalytic decomposition, aerobic breakdown is catalyzed, biodegradable, Physical Absorption, but have its limitation.
Ammonia chemical absorbing is ammonia and acidic materials is reacted using the alkalescence of ammonia and then produce low value-added nitrogenous fertilizer,
The method recovered solvent volatility is big, and corrosivity is strong, not disposable, and can not recycle gaseous ammonia, causes resource
Waste.
Ammonia catalytic decomposition technology is that ammonia is thoroughly decomposed into nitrogen and hydrogen in the presence of catalyst, but be presently, there are
The shortcomings that be, the decomposition of ammonia need to be carried out at high temperature.When temperature be less than 900 DEG C when, easily occur catalyst sulfur poisoning or
Phenomena such as producing ammonium salt blockage catalyst, but when temperature is more than 1200 DEG C, then Catalyst Steam can be made to press through high and accelerate to urge
The loss of agent, directly affect the service life of catalyst.Ammonia decomposition reaction thermal discharge is big, is not easily recycled utilization, causes ammonia to urge
Change and decompose power consumption height, operating cost is high, is not suitable in industrial production.
Ammonia catalysis aerobic breakdown technology is that ammonia is catalytically conveted into nitrogen and water under conditions of aerobic, and decomposition reaction exists
300 DEG C can be carried out, and completely eliminate the harm of ammonia, while also not produce secondary pollution.But the ammonia of method processing is dense
Spend relatively low, be not suitable for the processing of higher concentration ammonia, otherwise need to improve temperature, not only add energy consumption, and it can be promoted
The generation of his nitrogen ammoniate.The research of catalytic active component is concentrated mainly on noble metal and mistake in the aerobic breakdown of ammonia catalysis at present
Cross on metal oxide, noble metal catalyst typically has higher catalytic activity to ammonia catalysis aerobic breakdown, and reaction temperature exists
250 DEG C to 400 DEG C, but noble metal catalyst is poor to the selectivity of nitrogen, and be catalyzed aerobic breakdown and side reaction often be present, it is raw
Into nitric oxide, secondary pollution is caused, while noble metal catalyst is general costly, limits its application.Transiting metal oxidation
Thing catalyst has higher nitrogen selective with respect to noble metal catalyst, and cheap, but metal oxide oxidation catalyst activity
Not high, reaction temperature is higher.Therefore, either single supported precious metal catalyst or single carrying transition metal oxide catalyst
Agent, it can not all meet many requirements in industrial production to catalyst simultaneously.
Biological degradation method is the aerobic-anaerobic process using microorganism, and ammonia is converted into the nutrient source of microorganism so as to reach
To the purpose of purification air, but in industrial production, the ammonia of required purification is large-minded, and ammonia has toxic, and biological
Degradation treatment technology is not met by the demand in industrial production in the resistance to poison of biological inoculum and degradation efficiency.
The Physical Absorption of ammonia is the most common technology of ammonia removal, and the characteristic of water is highly soluble in using ammonia, with soft water or
Weak aqua ammonia is that absorbent absorbs ammonia, obtains low concentration ammoniacal liquor and then further distill to obtain concentrated ammonia liquor, and rectifying is concentrated ammonia liquor, then
Pressurized, liquefied ammonia use is made in condensation.In traditional chemical technique, absorption operation is a kind of important separation method, influences it
The factor of absorption is mainly solubility of the ammonia in water, and its absorption efficiency depends mainly on gas phase or liquid phase and ammonia on interface
Concentration difference, and ammonia is from gas phase to the diffuser efficiency of liquid phase transmission.This technique is disadvantageous in that ammonia is anti-with water
Substantial amounts of heat is released during answering, causes temperature drastically to raise, prevents ammonia to be dissolved in water so that liquid phase water is easy to tend to saturation
State, therefore, it is necessary to consume substantial amounts of water.And the recovery utilization rate of ammonia is not high, a large amount of weak aqua ammonias are produced in absorption process must
20% ammoniacal liquor must be condensed into by heating to be applied, and cost recovery is high, consumes big energy.
《Henan chemical industry》In《Spray column tail gas removes the experimental study of ammonia》Paper by spray absorber, with
Ammonia, air, dilute nitric acid solution are experiment thing system, have investigated sprinkle density, empty tower gas velocity, entrance ammonia density, absorbing liquid respectively
The influence of pH value and liquid phase temperature to ammonia absorptivity.Absorbent is delivered to absorption through circulating pump with certain flow in experiment flow
Column overhead, and be uniformly distributed into by liquid distributing board after droplet and gas is sprayed, the heat transfer of gas-liquid two-phase counter current contacting
Mass transfer, gas phase empty after tower top cyclone defroster.The spray of this device is uniformly distributed into droplet by liquid distributing board, compared to
Extensive packed tower, simple in construction, energy consumption is low.But its gas liquid interfacial area is small, absorbing the liquid phase after ammonia can not upgrade in time,
Mass-transfer efficiency is low.
《Chemical intermediate》Middle publication《The research of ammonia in rotary packed bed absorption phosphate tail gas》Describe it is a kind of with
Acid waste water is absorbing liquid, replaces traditional tower using rotary packed bed, the reality carried out to the ammonia in removing phosphate tail gas
Test.This experiment absorbs ammonia using acid, not equilibrium limited because sour absorption efficiency is higher.But ammonia absorption efficiency mainly takes
Acid content certainly in acid waste water, if acid amount deficiency, its absorption process translate into absorption process of the water to ammonia, limited
Acid is to its assimilation effect.And in the deamination experiment carried out to its tail gas, the device is applied to the suction of reaction of quick and moment
, certain risk be present in receipts process.Rotation filler inner edge is directly sprayed onto when waste water is passed through into liquid distribution trough, reacts contact surface
Product is small, and gas-liquid speed of related movement is low, and absorption efficiency is low, the problem of being also required to overcome gas-liquid skewness in tower during design.
