Description
Technical field
The utility model is related 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 in the way 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.The ferriferous oxide formed simultaneously in fixed catalyst surface has the effect of heterocatalysis, and fluid bed
Mode also promote chemical oxidation reaction and mass-transfer efficiency, so that the contaminant degradation rate in waste water is promoted.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 of sewage adds ionic type metal catalyst, and catalyst consumption amount is big.In treated sewage whole process, sewage, oxidation
The time of agent and catalyst reaction is shorter, and oxidant is to be fully used, not especially desirable to wastewater treatment efficiency.
Utility model content
The utility model provides a kind of novel Fenton fluid bed to solve the above-mentioned deficiency of the prior art.
The above-mentioned purpose of the utility model is realized by technical solution below：A kind of novel Fenton fluid bed, including
Reactor 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, urges from bottom to top
Agent fixation 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,
The water inlet pipe is connected to pre-mix zone, and outlet pipe is connected to overflow area, and the pre-mix zone passes through filter with catalyst fixation area
Plate separates；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
Circulating line, interior integrated circulating line are located at reactor tank interior, and interior integrated circulating line is equipped with circulating pump, and interior integrate is followed
The water distributor of endless tube road and pre-mix zone connects.
Further, the reactor top of the tank is provided with filler drug feeding pipeline.
Further, the reactor top of the tank is provided with aisle.
Further, the reactor tank body lower part is provided with maintenance door.
The utility model compared with prior art the advantages of be：
1, floor space is small.The utility model uses integration apparatus form, and inner loop pipeline is integrated into inside equipment,
And have ratio of height to diameter requirement to equipment from technique, to meet upflow velocity.Therefore equipment overall compact, floor space are small.
2, 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 improves the utilization rate of oxidant to substantially increase the reaction efficiency of oxidant and Pollutants in Wastewater
And pollutants removal rate.
3, catalyst amount is less.Catalyst is loaded on Fenton fluidized-bed reaction by the utility model as a fixed bed
Inside device, on the surface of fixed bed catalyst catalysis reaction occurs for sewage and oxidant, so as to avoid the loss of catalyst.Only
It need to periodically supplement on a small quantity, compare and greatly reduce the dosage of catalyst for traditional handicraft, while decreasing and containing
The yield of iron sludge.
