Description
Technical field
The utility model belongs to photocatalysis oxidation technique field, relates to a kind of reactor of photocatalytic pollutant degradation.
Background technology
Along with developing rapidly of Chinese society economy and significantly improving of living standards of the people, inevitably along with the discharge of a large amount of poisonous Recalcitrant chemicals, tradition pollutant processing method not only thoroughly can not eliminate degradation of contaminant, also easily cause secondary pollution, and the scope of application is narrow, only be applicable to specific pollutant, simultaneously also high along with energy consumption, be not suitable for the shortcomings such as large-scale promotion use.In recent years, utilize photocatalysis oxidation technique degraded and pollution abatement thing to obtain people more and more to pay close attention to, photocatalysis oxidation technique as the real eco-friendly novel green pollution plot technology of one, have easy and simple to handle, energy-efficient, reaction condition is gentle, can reduce the many merits such as secondary pollution.Nowadays, people are mainly divided into two parts for the research of photocatalysis technology, and one, research to photochemical catalyst; Two, the research of photocatalytic reaction conditions.Wherein, in the research of reaction condition, in order to the carrying out that photocatalysis oxidation reaction can be allowed efficient and stable, people design corresponding reactor for light-catalyzed reaction provides good platform.Photo catalysis reactor is the core of photocatalysis oxidation technique process pollutant, it is as the main equipment of photocatalysis oxidation reaction, determine problems such as the utilization rate of light source and the performances of catalyst activity, and these two factors determine the efficiency of light-catalyzed reaction.Therefore, manufacturing an efficient photo catalysis reactor is one of important step of carrying out photocatalytic pollutant degradation.
As can be seen here, the environment protection novel that photocatalysis oxidation technique is that a kind of technique is simple, energy consumption is low, non-secondary pollution and degraded have good development prospect thoroughly, but this technology can't realize industrialization so far, topmost reason is exactly lack efficient photochemical catalyst and design good photo catalysis reactor.
Utility model content
The purpose of this utility model is the defect overcoming the existence of above-mentioned technology, a kind of reactor of photocatalytic pollutant degradation is provided, this reactor embodies the optimum combination of light source utilization rate and catalyst activity, and at utmost can improve the reaction efficiency of whole reaction system, thus reach the object such as efficient, energy-conservation, stable.
Its concrete technical scheme is:
A kind of reactor of photocatalytic pollutant degradation, comprise reactor body 1, uviol lamp 4 is provided with at reactor body 1 bosom, described uviol lamp 4 outside is provided with quartzy cold-trap 3, described full quartz glass cold-trap 3 outside is provided with baffle plate 2, described reactor body 1 bottom is provided with liquid inlet 5 and gas access 6, is provided with gas vent 7 and liquid outlet 8 at reactor body 1 top.
Preferably, described baffle plate 2 is cylindrical.
Preferably, the bottom of described reactor body 1 is provided with ring-type aeration head.
Compared with prior art, the beneficial effects of the utility model are: the uviol lamp in reactor body is placed in centre, and wrap up with quartzy cold-trap, so both can, at guarantee high transmission rate, uviol lamp can be avoided again directly to contact with sewage, simultaneously because uviol lamp uses for a long time, the temperature too high life-span consuming lamp, and quartzy cold-trap can play the effect of cooling, extend the life-span of lamp, play the effect of economize energy.And the mounting means of the outer reaction zone of middle lamp can make the utilization rate of luminous energy reach maximum.
The centre of reactor body is the up-flow district of gas, solid, liquid three-phase, and outer Shi Jiangliu district, top is decanting zone, and bottom is recirculating zone, and is provided with ring-type aeration head in the bottom of reactor body, produces bubble.Not only give in reactor and be filled with oxygen, accelerate the speed of light degradation reaction; Simultaneously due to the effect of ascending gas bubbles, between up-flow district and Jiang Liu district, produce density contrast, order about fluid carry-over solid catalyst and circulate between Liang Qu, add the time of staying of pending liquid in reactor, be conducive to reactant liquor and react more fully.The amplification section at top defines buffering area, makes to bring about the desired sensation, solid, liquid three phase separation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reactor of the utility model photocatalytic pollutant degradation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in more detail.
With reference to Fig. 1, a kind of reactor of photocatalytic pollutant degradation, comprise reactor body 1, uviol lamp 4 is provided with at reactor body 1 bosom, described uviol lamp 4 outside is provided with quartzy cold-trap 3, described full quartz glass cold-trap 3 outside is provided with baffle plate 2, and described reactor body 1 bottom is provided with liquid inlet 5 and gas access 6, is provided with gas vent 7 and liquid outlet 8 at reactor body 1 top.Described baffle plate 2 is cylindrical.The bottom of described reactor body 1 is provided with ring-type aeration head.
The overall structure of the reactor of the utility model photocatalytic pollutant degradation adopts column type, and reactor is divided into three layers, and light source takes the outer reaction equation of middle lamp, and uviol lamp 4 is positioned at the centre of reactor body 1, makes the utilization rate of light source reach maximum; There is a columniform baffle plate 2 centre, carries out water conservancy diversion to treating material.Whole inside reactor is made up of up-flow district, Jiang Liu district, decanting zone and recirculating zone.Top is decanting zone, and gas, liquid, solid are separated in this section, and the supernatant outflow reactor after process, gas is directly overflowed by the opening at top.Uviol lamp 4 is placed in quartzy cold-trap 3, cools light source.
The above; be only the utility model preferably detailed description of the invention; 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, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.
