Description
Technical field
The utility model is related to a kind of simple in construction, reasonable in design, high-efficiency environment friendly, stable hydrogen peroxide oxidation tower.
Background technology
At present, the production method of hydrogen peroxide mainly has electrolysis, anthraquinone, isopropanol method, cathode anode reduction in the world
Method and direct synthesis from hydrogen and oxygen etc..Wherein anthraquinone is to produce the topmost method of hydrogen peroxide both at home and abroad at present.
As the development of Hydrogen Peroxide Production technology increasingly accelerates, the Quantity and scale in chemical plant are increasing, to environment
Influence also can not be ignored.The raising required with energy-conserving and environment-protective, tail gas recycle technology has also obtained significant progress.Current state
The exhaust gas processing device inside generally used mainly has water at low temperature to be also ice maker method；Carbon fiber adsorption and catalytic combustion method；Turbo-expander method.
Because ice maker method is that the direct cold produced using ice maker manufactures water at low temperature, then using water at low temperature in oxidized tail gas
Exchanged heat in cooler with tail gas, tail gas is cooled to reclaim aromatic hydrocarbons therein.Not only device is huge in operation process for ice maker
Big complicated, operation inconvenience, process control is difficult to realize automation, and arene content still has 2.15g/m3 in emission.Should
Concentration of emission undoubtedly causes severe contamination to air.This method is earliest tail gas aromatic hydrocarbons processing method, and its operating cost is higher.
Therefore directly oxidized tail gas recovery is carried out using the technique without man of dioxygen water factory now.
Carbon fiber adsorption and catalytic combustion retracting device, is with larger using NACF to various inorganic and organic gas etc.
Adsorbance and the faster rate of adsorption, and the characteristic of regenerating easily.NACF is made after felt, cylindric suction is rolled into
Attached core, is put into tubular or square absorber, and 3 absorbent cores are placed in ordinary circumstance tubular absorber, and square absorber places 2
Individual, 4 or 6 absorbent cores.2 and multiple adsorbers parallels can be set according to the exhausted air quantity that need to be handled, each absorber with
Waste gas, parsing steam, parsing lime set, the dry wind pipeline of whole device are connected, and constitute an absorbing recovery device, whole dress
It is equipped with PLC and automatically controls the related valve of switching, completes each absorption, parsing, drying process.Carbon fiber adsorption and catalytic combustion method
Due to the strong adsorption capacity characteristic using NACF, therefore the rate of recovery is higher, therefore is aoxidized in present hydrogen peroxide producer
What is used in solvent recovery technology from vent gas is relatively more, and using effect is preferably, the technological operation simple and stable, aromatic recovery rate
Height, there is good economic benefit.Turbo-expander method is a kind of novel oxidized method for recovering tail gas occurred in the recent period, its essence
It is also condensation at low temperature to be, but the overbottom pressure driving worm gear work done of technology utilization tail gas produces cryogenic media, power that should not be extra,
Therefore power consumption is smaller compared with carbon fiber adsorption and catalytic combustion method, also without steam consumption, therefore has one at energy-saving aspect
Fixed superiority, although the technique oxidized tail gas aromatic recovery rate effect is preferably, technique is to reclaim aromatic hydrocarbons using cryogenic condensation
Compared with NACF reclaims heavy aromatics using characterization of adsorption, reclaim and also have certain gap.For energy consumption angle, hydrogen peroxide
The best mode of vent gas treatment is turbine expansion, and it can make full use of the pressure energy of tail gas, and only domestic technology is not also very
It is advanced, mainly 3 points:One is that the temperature of refrigeration can not be too low, external up to subzero tens degree, and two be that machine runs and is not
Very stable, three be that mist eliminating foam removal effect is poor.
