Description
（One）Technical field
It is the present invention relates to a kind of environmental protection equipment, more particularly to a kind of for the centrifugation of the mechanical energy of flue gas desulfurization and dedusting and sewage water denitrification
Formula washs bed cleaning equipment.
（Two）Background technology
Traditional dedusting, desulfurization and waste water blowoff nitrogen be all by the way of static filler or filter, by static filler or
Filter specific surface area is dusted and gas-liquid mixed, to reach treatment effect.The shortcomings that traditional approach:Filter is easily stifled
Plug, block after cause self resistance to be multiplied, cause treatment effeciency low, and impacted to production status, cleaning and more
It changes filler or filter is time-consuming and laborious and increase operation and maintenance cost, very big inconvenience is brought to user.
Centrifuge washing bed cleaning equipment is exactly a kind of novel reactor for strengthening chemical transmitter process, net in centrifuge washing bed
Change in equipment and be provided with high-speed rotating packing layer core, makes the liquid phase being passed through from revolving bed center by the penetrating hole of packing layer core
The centrifugal force generated when gap, liquid are made it in filler in-core by the shearing and dispersion of height, by liquid by significant shear force effect
Body tears the silk, film and drop at micron to nano grade, forms huge interphase interface, and interface configuration generates the variation and more of high speed
Newly, it is alternate efficient to complete two with the another kind of medium for being passed through revolving bed simultaneously for the necessary condition for changing two mass-transfer efficiencies
Chemical transmitter process can make liquid phase mass transfer coefficient improve 1-2 quantitative levels.
Centrifuge washing bed cleaning equipment is a kind of novel reactor for strengthening chemical transmitter process, is that a chemical industry mass transfer is anti-
The technical equipment answered, is known as cross-centennial technological break-through, and centrifuge washing bed cleaning equipment is also known as the " crystal of chemical industry
Pipe ".
It is seldom in the application of engineering field although the principle of this technology is known dawn already, it is basic at present
The laboratory test stage is rested on, the centrifuge washing bed cleaning equipment applied on a small quantity in industrial system is generally also only on probation
Stage is not yet widely applied and is promoted, currently, Major Difficulties of the higee technology equipment in engineer application
It is：
1. since centrifuge washing bed cleaning equipment gravity coefficient is directly proportional to revolution, revolution is higher, and mass-transfer efficiency is higher, but due to
It being limited by Structural Dynamics, the structure size of high-speed rotating packing layer core cannot be made big, cause circulation area smaller,
It can only be applied to above the engineering project of small flow medium at present；
2. since centrifuge washing bed cleaning equipment revolution is higher, the packing layer core of revolving bed often all makes one group of single ring-type
Rotation body structure is limited to limitation of the fluid in packing layer in-core flowing velocity, and the speed of medium injection can not be very big, and liquid is situated between
When matter injection rate is excessive, Concerning Flooding Phenomenon will be generated, just destroys the working condition of mass transfer system, causes the mass transport process of system not
It can stablize and carry out；
3. past in structure since liquid phase medium needs the center cavity for entering rotary body from the one end for rotating bed body rotary shaft
Toward the bearing arrangement for axis being designed to single-ended support, the support construction of this cantilever limits the length and revolution of rotary shaft, revolves
The circulation area of rotated bed packing layer core is difficult to extend.
According to the above several points, the packing layer core of revolving bed all extremely has relative to the flowing velocity and circulation area of medium
Limit, cannot handle the air-liquid state medium of big flow, its application range is made to be very restricted.
Such as in boiler flue gas desulfurization decontamination process, the process reaction in terms of progress gas-liquid mass transferring is needed, due to
There are problem above, the high-gravity rotating bed mass transfer processing that can't be adapted between big flow gas-liquid medium.
