Description
Technical field
The present invention relates to a kind of fluid bed more particularly to a kind of novel Fenton fluid beds.
Background technology
Fenton fluid bed is cyclic chemical oxidation reactor in a kind of efficient stationary catalyst bed, is by traditional Fenton oxygen
Change change of technique.Fenton fluid bed enables the ferric iron major part produced by Fenton methods using the mode of fluidized bed
Crystallization or precipitation be coated on fluidized bed fixation catalyst surface, be one combine same phase chemical oxidation i.e. Fenton methods,
Out-phase chemical oxidation H202/Fe00H, fluidized bed crystallization and Fe2O3H2The new technology of the functions such as the reduction of dissolved of O.This
Technology has carried out further improvement to traditional Fenton oxidation method, reduces a large amount of chemical sludge yield of Fenton methods, with
And the loss of catalyst.Effect of the ferriferous oxide with heterocatalysis formed simultaneously in fixed catalyst surface, and fluid bed
Mode also promote chemical oxidation reaction and mass-transfer efficiency, promote the contaminant degradation rate in waste water.Fenton fluid bed with
Fenton technology is compared, it has oxidant utilization high, and catalyst amount is few, and operating cost is low, integration of equipments degree height etc.
Advantage.But traditional fenton catalyst is dissolved in sewage water with ionic forms, and as sewage flow is lost in, Fenton processing
The equal whole process addition ionic type metal catalyst of sewage, catalyst consumption amount are big.In treated sewage whole process, sewage, oxidation
The time of agent and catalyst reaction is shorter, and oxidant is not especially desirable to wastewater treatment efficiency to be fully used.
Invention content
The present invention provides a kind of novel Fenton fluid bed to solve the above-mentioned deficiency of the prior art.
The above-mentioned purpose of the present invention is realized by following technical solution：A kind of novel Fenton fluid bed, including reaction
Device tank body is provided with water inlet pipe and outlet pipe on reactor tank body, and reactor tank body is divided into pre-mix zone, catalyst from bottom to top
Fixed area and reaction zone, reaction zone top are water outlet weir plate, and overflow area is provided between water outlet weir plate and reactor tank body, described
Water inlet pipe is connected with pre-mix zone, and outlet pipe is connected with overflow area, and the pre-mix zone passes through filter plate point with catalyst fixation area
Every；The pre-mix zone is equipped with water distributor, and the reaction zone is equipped with flow straightener；The overflow area is connected with interior integrated cycle
Pipeline, interior integrated circulating line are located at reactor tank interior, and interior integrated circulating line is equipped with circulating pump, interior integrated circulation pipe
The water distributor of road and pre-mix zone connects.
Further, it is provided with filler drug feeding pipeline at the top of the reactor tank body.
Further, it is provided with aisle at the top of the reactor tank body.
Further, the reactor tank body lower part is provided with maintenance door.
Compared with the prior art, the present invention has the advantages of：
1st, floor space is small.The present invention uses integration apparatus form, and inner loop pipeline is integrated into inside equipment, and from
There is ratio of height to diameter requirement in technique to equipment, to meet upflow velocity.Therefore equipment overall compact, floor space are small.
2nd, oxidant utilization improves.Fenton fluidized-bed reaction mechanism is pollutant in oxidant and waste water in reactor
Catalysis reaction occurs for the catalyst filling surface of inside filling, and the circulatory system of fluid bed is by the multiple overcurrent of inside reactor waste water
Catalyst surface so as to substantially increase the reaction efficiency of oxidant and Pollutants in Wastewater, improves the utilization rate of oxidant
And pollutants removal rate.
3rd, catalyst amount is less.Catalyst is loaded in Fenton fluidized-bed reactor by the present invention as a fixed bed
Catalysis reaction occurs on the surface of fixed bed catalyst for portion, sewage and oxidant, so as to avoid the loss of catalyst.Need to only it determine
Phase supplements on a small quantity, compares and greatly reduces the dosage of catalyst for traditional handicraft, while decreases iron content dirt
The yield of mud.
