Description
Technical field
This utility model is related to a kind of tail gas of sulphur high gravity desulfurization device, belongs to technical field of desulfurization.
Background technology
Tail gas of sulphur is the important emission in sulfur commercial production, wherein containing substantial amounts of sulfide and nitride, directly
Run in put and can cause the destruction to environment, according to the requirement that Environmental is administered, GB31570-2015 is proposed and sulfur is returned
The emission request of sulfur dioxide in tail gas is received, needs the content of sulfur dioxide to be controlled in 100mg/m3Within.
At present, the common technique to Sulphur tail gas desulfurization process includes：Thermal incineration method, catalytic burning method, Reducing and absorption
Method, reduction catalystses oxidizing process.Thermal incineration method is to carry out high-temperature process in the environment of 600 DEG C to tail gas of sulphur, burning method process
In tail gas of sulphur afterwards, content of sulfur dioxide is still up to 400mg/m3；Catalytic burning method is relatively low than the temperature of thermal incineration method, is
Carry out heat treated in the environment of 350-430 DEG C to tail gas of sulphur, but sulfur dioxide in the tail gas of sulphur after catalytic burning
Content equally be higher than 200mg/m3, still do not meet the emission request of GB；Reducing and absorption rule be in tail gas sulfur and
Sulfur dioxide carries out hydrotreating and generates hydrogen sulfide, at the same the hydrolysis for carrying out cos and Carbon bisulfide generate hydrogen sulfide and
Carbon dioxide, now in tail gas of sulphur, the content of sulfur dioxide can reach 200mg/m3；Reduction catalystses oxidation rule is also
On the basis of former absorption process, act on further with catalyst for selective oxidation, hydrogen sulfide and oxygen are reacted generation simple substance
Sulfur, but after processing, in tail gas of sulphur, the content of sulfur dioxide is still uncontrollable in 200mg/m3Within.
Additionally, also injection venturi (JEV) wet washing, the method using NaOH as a mobile phone, using absorption tower
Desulfurization, alkali liquor are sprayed into from tower top, and tail gas of sulphur is flowed up so as to the counter current contacting in the tower by bottom of towe, and mass transfer and reaction occur,
So as to reach the purpose of desulfurization, but the method is all very big for the scale of equipment and the requirement of investment, and universality is not strong.
EDV wet scrubbing methods, organic catalysis smoke comprehensive are controlled logos and similarly there is this.
Hypergravity is the power under many environment bigger than terrestrial gravitation acceleration suffered by material.Under Elevated Gravity,
The diffusion of different size intermolecular molecule and interphase mass transfer process than conventional articulated gravity off field much faster.Solution-air, liquid-liquid,
Liquid-solid biphase and airwater mist cooling produces flowing contact under Elevated Gravity, in the filler of multi-pore channel, greatly shears
Liquid can be shredded into power liquid film, drop and the brin of micron to nano grade, produce boundary that is huge and quickly updating.Make
Alternate mass transfer rate improves 1-2 numbers than the 1-3 order of magnitude, the production efficiency of unit equipment volume are improved in traditional tower
Magnitude.
So, efficient hypergravity machine is designed, and realizes the desulfurization to tail gas of sulphur, be urgently to be resolved hurrily at present asking
Topic.
