Effect of the invention is that:
1, both the flue gas for burning generation was handled, while having carried out the nocuousness such as heavy metal to the flying dust generated is burned
Substance processing, and the water to contain hazardous substance after processing has also carried out separating-adding alkali reaction-separation mode to processing water
It is handled, to realize the full processing of solid, liquid, gas, is truly realized harmless treatment.
2, it burns in the flue gas of generation containing lower nitrogen oxides and oxysulfide, by spraying ozone, while also spraying
Steam water interface, so that lower nitrogen oxides are relatively high higher nitrogen oxides, then higher nitrogen oxides by ozone
Be dissolved in water (trivalent and pentavalent nitrogen oxides is only absorbed by the water to form acid), at the same oxysulfide be also dissolved in water it is (anti-with water
Acid should be formed), flue gas enters in primary adsorption room with these acid solutions, and steam dissolves calcium oxide particle surface to form hydrogen
Calcium oxide solution, and calcium hydroxide solution reacts i.e. forming salt with acid, thus by harmful nitrogen oxides and sulphur oxygen in flue gas
Compound is adsorbed.There can be the harmful substances such as some heavy metal elements in flue gas simultaneously, by being arranged in primary adsorption room
Active carbon particle, these harmful elements are adsorbed.It is entered in secondary absorption room in flue gas, remaining steam in flue gas
(also including solution) is further oxidized calcisphere adsorption, to play dry purpose to flue gas.
3, the harmful elements such as heavy metal in medical flying ash are dissolved into pure water by supercritical water reaction, and are uniformly released
It is put into arc in filter plate, by high speed rotation, is separated solution and solid burning ash using centrifugal force.Work as liquid
When arrival in outer filter plate inner membrance, due to the inner membrance be it is non-penetrating, fluid preservation in the position, passes through rotation at this time
Turn for the alkaline matters such as calcium hydroxide to be discharged into solution, calcium hydroxide reacts generation with harmful elements such as heavy metals in solution
Precipitating pumps inner membrance at this time and continues high speed rotation, to precipitating be separated with processing water, the water after realizing supercritical water treatment
It is not contaminated.
Pass through the interior filter plate of setting specific structure (coaxial, hollow hemisphere body, interior accessibke porosity, and film is set in outer arc)
Cooperate with outer filter plate and inner membrance, two steps filtered and the reaction between the filtering of two steps is completed during same,
To greatly improve the treatment effeciency of processing water.
