Description
Technical field
The present invention relates to a kind of wet oxidation reactor with filler bed structure.
Background technology
At present, 2015, China's waste water total release was about 50,000,000,000 tons, and industrial wastewater is up to 22,000,000,000 tons, and wherein superelevation is dense
Waste water (cod is about 20000mg/L to 150000mg/L) total emission volumn is spent up to 1,000,000,000 tons or so.More than 70% ultrahigh concentration work
Industry waste water is simultaneously discharged directly into water body without effectively processing.Such waste water possesses high organic matter, high salt and deposited；Waste component is answered
It is miscellaneous；Colourity is big, and smell is big；With strong acid and strong base and corrosivity.Water body is such as directly entered, the dissolving in water body can be largely consumed
Oxygen, destroys water body environment；Sense organ contact scar；Institutional harm etc..Existing bi-membrane method, biochemical process and multiple-effect evaporation method can not
Effectively solve this important pollution problem.Since the nineties in last century, field of Environment Protection starts to introduce wet oxidation this concept,
And carried out being up to the theoretical research in more than 20 years on this basis.Given up although Wet Oxidation Process can effectively solve ultrahigh concentration
The pollution problem of water, but the technology only rests on the pilot plant stage of theoretical research and laboratory scale at present, in other words,
Most of researchers are the equipment using laboratory scale, and existing industrial wastewater is carried out with the mechanism of wet oxidation can
Row is tested, and only the R＆D team of only a few is promoting the process of industrialization of the technique, includes among these in pushing course
The research work of substantial amounts of cross discipline is needed, not the problems such as not possessing design of pressure vessels and manufacture qualification, this is in those early years being handed over
Interdisciplinary mutual exchange is pitched also not as nowadays such frequently period, the research progress of the technology is hindered significantly.
Current Domestic does not also have full maturity and efficient wet oxidation device is putting into production and used, and in
This simultaneously, with the acceleration of Chinese Industrialization process, the people to environmental protection demand increasingly improve, country sustainable development is compeled
It is essential and wants, increasing ultrahigh concentration waste water fails to deal carefully with, and is seriously asked which results in substantial amounts of environmental pollution, stopping production etc.
Topic.Part wet oxidation reactor still has various disadvantages during practice：
Part wet oxidation reactor is without cooling system, it is impossible to will a large amount of reaction Hot swappings present in course of reaction to setting
It is standby outer, superpressure, overtemperature or even the hidden danger exploded are caused at work；
Filler device is not present in part wet oxidation reactor, it is impossible to uses solid catalysis mode CWO, leads
Cause reaction to need high temperature and pressure just to carry out, high manufacture level not only needed in equipment Manufacture Process,
More dangerous hidden danger has been also taken in operation.Homogeneous catalysis method is used in some techniques, though avoid in reactor
Filling-material structure, but catalyst generates secondary pollution to waste water, and homogeneous catalysis effect is not ideal enough；
Filler device is not present in part wet oxidation reactor, without effective mixed flow effect in air-liquid mixed process, makes
Relatively low into the mass-and heat-transfer speed between air-liquid, the time required for reaction is increased substantially, and disposed of in its entirety energy consumption is also carried therewith
It is high.
