Background technology
Under domestic water pollutes the situation of day by day serious, water scarcity, traditional sewage water treatment method has been difficult to the standard reaching discharge and reuse, and therefore advanced treatment of wastewater technology has become the research emphasis of this area.
Catalytic ozonation is one of most effective means of advanced treatment of industrial waste water, and for the research of catalytic ozonation most crucial be exploitation and the use of catalyzer, as everyone knows, fine catalyst activity is high, catalytic efficiency is high, and consumption is few, but is separated and reclaims use difficulty.At present, the main preparation method of ozone catalytic oxidation catalyst is with aluminum oxide or haydite ball for carrier, on surface by metal with transition metal oxide together with inorganic adhesive, through sintered at high temperature loaded catalyst.Catalyzer prepared by this processing method has following deficiency, one, and catalytic activity comparatively powder catalyst has substantial degradation; Its two, in water, catalyst outer layer easy powder of detached more than month or after the longer time, affects its catalytic activity and block system; Its three, the contaminated or fouling of catalyzer dirty stifled after, not easily regenerate.Therefore can efficiency utilization catalyzer be how the difficult point of this area always.
Utility model content
For solve catalytic ozonation fine catalyst in prior art not easily separated and reclaim, easily block system, problem that service efficiency is low, the utility model provides a kind of catalytic ozonation reactor that can make full use of catalyzer.
The utility model is achieved in that a kind of catalytic ozonation reactor, comprises reactor body, film pipe, central tube, waterwater entrance, water outlet and drain; The bottom of reactor body is provided with waterwater entrance, and upper end is provided with drain, and the side of reactor body is provided with water outlet; Be provided with central tube in reactor body, the two ends of described central tube are fixed by tube sheet; Described film pipe two ends are fixed by tube sheet and seal, and film circumference of cannon bone is around central tube circumferentially shape arrangement, and intercommunication between each film pipe, central tube is communicated with film pipe.
Further, described film pipe is ceramic-film tube or titanium alloy bar or titanium alloy tube, and this film pipe is the pipe of 5 ~ 10 microns, aperture, diameter 20 ~ 40 millimeters, length 1 ~ 1.5 meter.
Further, described central tube to be diameter be vitrified pipe or the stainless steel tube of 100 ~ 300 millimeters.
Described catalytic ozonation reactor one or more groups be connected in parallel and carry out catalytic ozonation reaction with tank of intaking, waste water pump, product water pot.
The utility model effectively can solve separation and the recovery problem of fine catalyst, improves the service efficiency of catalysis.Effective minimizing catalyzer usage quantity, reduces running cost; Avoid the problem of working load type catalyzer efflorescence inactivation in water, improve operation stability and efficiency; This device can realize the hybrid reaction that internal recycle promotes waste water and catalyzer, and effectively realize waste water catalytic oxidation and wastewater membrane and be separated and synchronously carry out, production water water quality is good.

Wherein, 1, central tube, 2, film pipe, 3, waterwater entrance, 4, water outlet, 5, drain.
Embodiment
Below by embodiment, the utility model is described further.
As shown in Fig. 1 ~ 2, catalytic ozonation reactor comprises reactor body, central tube 1 and film pipe 2; Be provided with central tube 1 in reactor body, this central tube 1 is the stainless steel cylinder of diameter 100-300 millimeter, and the two ends of described central tube 1 are fixed by tube sheet, and one end is placed in reactor body inside, and the other end passes body; Described film pipe 2 is aperture 5-10 micron, diameter is 20-40 millimeter, the tubular type ceramic-film tube 2 of long 1-1.5 rice, its two ends are fixed by tube sheet and are sealed, ceramic-film tube 2 is around central tube circumferentially shape arrangement 1 ~ 5 layer, ceramic-film tube 2 internal mutual leads to receives outside lift pump and backwash pump, and central tube 1 is communicated with film pipe 2.Central tube 1 both can play a supportive role, again can as ascent stage catalyst oxidation reactor; Reactor body is also provided with waterwater entrance 3, water outlet 4 and drain 5.
The composition metal filtered out for different quality and catalyst of transition metal oxide are processed into the ultrafine powder of 50-100 micron (150-300 order), effectively to improve the activity of catalyzer.Ozone catalytic oxidation catalyst ultrafine powder is joined in reactor, pending trade effluent and ozone gas is passed into from the bottom waterwater entrance 3 of central tube 1, in central tube 1, waste water rises abundant contact reacts together with ozone and ultrafine powder catalyzer, solid-liquid separation is realized in the ceramic-film tube 2 flowing through surrounding, waste water after partially disposed is by outside water outlet 4 outlet pipe, and catalyzer drops to reactor bottom with steam, central cylinder 1 secondary response is again mixed into the waste water newly entered and ozone, form the continuous hybrid reaction of internal recycle, thus effectively improve the performance of chemical oxygen demand (COD) in catalytic ozonation degrading waste water, the difficult problem that fine catalyst is difficult to be separated and reclaim can be solved very well.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
