Description
The utility model relates to a kind of photochemical catalysis fluidizing reactor, is that photocatalytic degradation is handled the contained organic equipment of organic sewage.
Light-catalyzed reaction is with TiO
2Deng conductor oxidate is photocatalyst, under the light source irradiation of UV-light or near-ultraviolet light, bubbling air or oxygen make in the sewage organism produce a series of redox reaction on the photocatalyst granular surface, be degraded to innoxious substances such as water and carbonic acid gas, reach emission request.This method also is applicable to removes contained organism in other liquid.Existing photo catalysis reactor mostly is fixed bed reaction, and granules of catalyst is in static condition in reactor, and the contact area of it and gas, liquid reactant is little, speed of reaction and inefficiency.
The purpose of this utility model provides a kind of photochemical catalysis fluidizing reactor, it can make photocatalyst granular be suspended in the gas-liquid mixture, thereby increase the contact area between photocatalyst and gas, the liquid reactant, and the removal process of light-catalyzed reaction and photocatalyst is finished in device automatically continuously, improve organic matter degradation rate and sewage purification working efficiency.
The utility model photochemical catalysis fluidizing reactor adopts following structure: the turriform reactor comprises lower reaction zone and the abscission zone, top that fuses, ultraviolet source and quartzy cold-trap are housed in the tower, the tower inner bottom part is equipped with the porous aeration board, the tower wall that is positioned at the aeration board upside is provided with the organic sewage feed-pipe, the downside tower wall of aeration board is provided with oxygen-containing gas and is blown into pipe, cat head is provided with the gas spillway, and wire mesh demister is housed, and the upper portion side wall of tower is provided with the water purification upflow tube.Said disengaging zone diameter can be designed to the diameter greater than reaction zone, to reduce the disengaging zone height.Above-mentioned aeration board can adopt porous ceramic plate or POROUS TITANIUM metal sheet, aperture≤1000 μ m.The photocatalyst granular of this reactor is packed into above the interior aeration board of tower, organic sewage is sent in the tower from the sewage import, oxygen-containing gas is gone into tower and is formed upstream by the aeration board micropore from the aeration board downside by the air pump pressurization, the air-flow entrained catalyst particles, making it be fluidization is suspended in the gas-liquid material, gas-liquid-solid three-phase fully contacts, under UV-irradiation, organism in the material produces redox reaction, be degraded into water and carbon dioxide, carbon dioxide is from the tower top discharge atmosphere, and purifying waste water after the degraded goes out tower from overflow port and collect or discharge.
In sum, the utility model reactor adopts the porous aeration board to form upstream in tower, be suspended in the gas-liquid material thereby photocatalyst granular upwards carried secretly, make in the tower gas-liquid-solid three-phase material be fluidization and fully contact, improved the efficient of light-catalyzed reaction greatly.In addition, this reactor can make light-catalyzed reaction, feed separation, each process of catalyst recovery finish automatically in tower, need not to establish in addition separating and reclaiming device, this is because the fully reaction and when continuing to rise in reaction zone of gas-liquid-solid three-phase material, three phase materials separate in the disengaging zone gradually because of the difference of proportion: the big sedimentation downwards of granules of catalyst proportion is returned reaction zone and is reacted, carbonic acid gas and other gaseous substance bubbling to the cat head that makes progress is discharged, and the water after the degraded overflows system automatically from overflow port.As seen the utility model is simplified organic sewage photocatalytic degradation treatment facility, and efficient improves, and cost reduces, and is convenient to industrialization promotion.
Below in conjunction with description of drawings structure of the present utility model.
Fig. 1 and Fig. 2 are respectively the structural representations of two embodiment of this photochemical catalysis fluidizing reactor.
As shown in Figure 1, in the turriform reactor 2 (to call " tower " in the following text) ultraviolet source 4 is housed, light source is put into columnar quartzy cold-trap 3, and cold-trap contains interlayer, and water coolant feeds from the entrance end 3-1 of interlayer, discharges from exit end 3-2, in order to attemperation.The bottom of tower 2 is reaction zone 2-2, and the top expansion section s is disengaging zone 2-1, and the disengaging zone enlarged-diameter is in order to increase circulation area, the material lift velocity to be reduced, accelerating to separate, and can reduce the height of tower.In the present embodiment, quartzy cold-trap 3 runs through two districts up and down, and ultraviolet source 4 is arranged in the lower reaction zone.The tower inner bottom part is equipped with aeration board 5, and this aeration board adopts porosity 〉=20%, the porous ceramic plate of the aperture of micropore≤1000 μ m.The feed-pipe 8 of reaction tower is located at the upside of aeration board 5, and this pipe is provided with valve 8-1, and air (or oxygen-containing gas) inlet pipe 6 is located at the downside of aeration board 5, and this pipe is provided with valve 6-1.The upper end pneumatic outlet of disengaging zone 2-1 is provided with wire mesh demister 1, and the sidewall of disengaging zone is provided with upflow tube 7.Present embodiment also is provided with feed-pipe 9 and valve 9-1 at the bottom of the tower, adopts this feed-pipe, can make the below charging of sewage from aeration board 5, forms the multiply ascending current by the aeration board micropore, and photocatalyst granular is carried secretly by current simultaneously and upwards suspended.The organic sewage charging can select to manage 8 or manage 9 and go into tower, and it is to realize by the control to valve 8-1,9-1.
Fig. 2 embodiment and Fig. 1 difference are that quartzy cold-trap 4 is fixed in the lower reaction zone 2-2, and upper and lower two district's diameters of tower are identical, but because cold-trap 4 un-occupied space in the disengaging zone, so the actual circulation area of disengaging zone 2-1 is greater than reaction zone.
Be the working process that opening for feed explanation the utility model reactor is used for the organic sewage degradation treatment to manage 8 below.Photocatalyst TiO packs in the tower
2Particle, light source 4 energising work, cold-trap 3 feeds the cold water attemperation.Shut-off valve 9-1, open valve 8-1 and valve 6-1 in feed-pipe 8 input towers, pump into air from managing 6 with pending organic sewage simultaneously.Air is gone into tower from the downside of aeration board 5, and the micropore by aeration board 5 enters reaction zone 2-2, and air-flow bubbling in water layer rises, and upwards carries photocatalyst TiO simultaneously secretly
2Particle, granules of catalyst is suspended in water, thereby gas-liquid-solid three-phase becomes fluidized fully to contact, under UV-irradiation, organism carries out redox reaction and is degraded to innoxious substances such as water and carbonic acid gas, material continues to rise in the 2-1 of disengaging zone in the tower, and three phase materials separate automatically because of difference of specific gravity: catalyzer TiO
2Particle is got back to the new reaction of participation in the reaction zone 2-2 because of the downward sedimentation of deadweight effect; Carbonic acid gas and other gaseous substance continue upwards, and bubbling to cat head enters in the atmosphere through silk screen scum dredger 1; The water of purifying waste water and reacting generation after the degraded is from upflow tube 7 discharge systems, and this water can be collected or discharge.As it is still below standard to discharge in the water of system organic content, then can be with overflow drainage water access tube 8 repeated several times degraded again, until up to standard.
