Description
Technical field
The invention belongs to water treatment facilities studying technological domain, in particular to a kind of gas-liquid mixed reactor, more particularly to
A kind of Y type gas-liquid mixed reactor of micro air bubble processing organic pollutant.
Technical background
With making rapid progress for scientific technological advance, water pollution problems is increasingly severe, how to have solved water pollution problems
Become a focus of society and country's concern.It is shown according to China's water investigation in 2014: national ten big Drainage Water Qualities one
Half pollutes；Emphasis lake water quality 4 is controlled into pollution in state；31 large-scale water quality 17 pollutions of freshwater lake；In 9 important bays, the Liao Dynasty
It is big-and-middle to 118 that Dong Wan, Bohai Sea Gulf and Jiaozhou Bay's water quality inferiority, entrance of Changjiang River, Hangzhou Wan, Minjiang Estuary and the mouth of the Zhujiang River water quality are very poor ...
The water body that city is investigated shows that serious pollution accounts for 40%, and the bad V class of surface water (losing the water for using function) section ratio reaches
30% or more, contaminated underground water accounts for one third in national 4778 groundwater monitoring points, about sixty percent water quality it is poor and
It is very poor.Have 33% in 6834 Water Functional Zones that national main river,lake and reservior delimited according to " national comprehensive planning of water resources "
Water Functional Zone COD or ammonia nitrogen status pollutant enter river amount be more than its pollutant carrying capacity, and be its pollutant carrying capacity 4-5
Times, partial rivers (section) are even as high as 13 times.It is investigated according to the United Nations, China is one of 13 poor-water states in the world, currently, entirely
State year nearly 6200 billion cubic meter of water total amount, more than 500 billion cubic meters of normal year water shortage, with socio-economic development and global gas
Waiting variation influences aggravation, and the contradiction of supply and demand for the water resource will be more sharp, and on the one hand many water resources can not recycle, and aggravate water money
The deficient degree in source, the sustainable use of another aspect environment and economic sustainable development are seriously affected, and therefore, solve water
The harm of environmental pollution is of great practical significance with prevention and treatment.
Ozone is as a kind of high-level oxidation technology, and since it has extremely strong oxidisability, it is single former to decompose generation in water
The extremely strong substance of the oxidabilities such as sub- oxygen and hydroxyl can aoxidize gas chromatography and inorganic matter, thus obtain in water process
It is widely applied.But ozone is that there is the size of bubble diameter also affects the place of ozone in the form of bubble in water body
Manage effect.Since the eighties in last century, the researcher of countries in the world all attempts the smaller bubble application of diameter and water
Body reparation, the contact area that can be considerably increased with water because the diameter of bubble becomes smaller, while bubble surface energy, liquid-vapor interface
Upper gas molecule proportion, bubble service life all can significantly increase, various reaction speeds are also increase accordingly, gas transfer
Rate greatly improves.Then various microbubble generators come into being, and common is that Venturi tube or turbine generate gas-liquid mixed,
Moment has produced a large amount of micro-bubble, but micro-bubble mutually collides merging and easily becomes air pocket, affects bubble
Treatment effect, in order to solve this problem, the present invention design a kind of new reactor, and the merging of bubble can be effectively reduced, and accelerate
Bubble is to the degradation of water pollutant and repairs ability again.
Summary of the invention
Air pocket, this hair are formed in order to overcome the problems, such as that microbubble present in existing microbubble generator is easy to merge
Bright to provide a kind of merging that can effectively prevent bubble, the mixing of speed up gas and liquid improves degradation and the remediation efficiency of water pollution,
And the Y type gas-liquid mixed reactor of processing time can be shortened.
The technical scheme adopted by the invention is that: this kind of Y type gas-liquid mixed reactor includes reaction supervisor 1 and is serially connected in
The n order reaction branch pipe group of 1 outlet end of reaction supervisor, n=1,2,3；Every first order reaction branch pipe group includes 2~4 be set side by side
In the reaction branch pipe that diffused is distributed, n-th grade of reaction branch pipe central axis is formed between branch pipe central axis with (n-1)th grade react
5~10 ° of angle, n-th grade of reaction branch pipe cross section S meet with (n+1)th grade of the branch pipe cross section s that reacts: S=9~12s.
