Abstract
The utility model relates to a separating device of entrainment in an outlet gas in gas-liquid mass transfer equipment in the field of chemical industry, in particular to an inertia-collision-type mist eliminator, which comprises a plurality of mist eliminator units which are arranged in parallel, wherein each mist eliminator unit is provided with an inlet pipeline and an outlet pipeline, and outlet pipelines are connected by valves. In heavy load, the valves of all mist eliminator units are opened; in light load, the valves of part of the mist eliminators are opened, and the loads of part of the mist eliminator units are still in a design range, so that the mist eliminator has a larger application range, and still keeps about 99% of entrainment removing efficiency under the condition of heavy load fluctuation.
Description
Technical field
The utility model relates in the gas-liquid mass transfer (contact) equipment of chemical field the separator of mist in the exhaust gas body, especially a kind of inertial collision type demister.
Background technology
The gas-liquid mass transfer (contact) equipment that is used for chemical field at present; gas in mass transfer apparatus and liquid carry out carrying out chemical reaction etc. between quality transmission and heat transmission and gas-liquid; the gas mist of when leaving mass transfer apparatus, can having carried under one's arms; need to be separated the amount of carrying under one's arms sometimes, therefore need to install demister with liquid in protection upstream device or the reduction gas.According to demister remove the classification of mist principle, inertial collision is exactly wherein a kind of, specifically includes woven wire demister, cylinder demister etc.Inertial collision type demister is comparatively responsive to gas flow fluctuation, gas flow rate excessive or too small all will influence inertial collision type demister except that mist efficient.
In practice, by load fluctuation situation to institute's use demister, the concrete size and the parameter of design demister.General under the little situation of load variations, can meet design requirement substantially.
For example, certain inertial collision type demister, this model demister design load fluctuation 80-120%, this type demister is more than 99% except that mist efficient in the 80-120% scope, if but load less than 80% or load greater than 120%, this type demister removes mist efficient will be lower than 99%.
Under the above-mentioned duty for high load capacity, the design by to required demister the time solves the fluctuation problem of high load capacity.And in case design and determined the size and the rated load of demister, then fluctuation problem under the underload duty just is difficult to resolve and determines.For example, when having a device load fluctuation now at 50-120%.If adopt above-mentioned demister design, because this type demister design range of load fluctuation is 80-120%, then foam removal efficient is inevitable less than 99% when 50% and 70% load.
In addition, when at underload, under the long-term obsolete situation of the part parts of above-mentioned demister,, can cause the corrosion of demister parts owing to do not capture the washing of acid.
Summary of the invention
Problem to be solved by this invention, be when inertial collision type demister under the situation of big load fluctuation, still keep removing mist efficient about 99%.
Concrete technical scheme of the present utility model is:
A kind of block form inertial collision type demister is made up of by arranging side by side some demister unit, and each demister unit is respectively equipped with inlet pipeline and outlet conduit, and each outlet conduit connects by valve.
The load of described demister unit is provided with according to a certain percentage to adapt to different load ranges.The structure of each demister unit all can adopt known technology of the prior art, relevant above-mentioned known solution, and those skilled in the art all understands, and does not repeat them here.
When big load, the valve of all demister unit is all opened; When underload, only open the part demister unit, to this part demister unit, its load still within scope of design, thereby make demister possess bigger accommodation, especially adapt under the situation of big load fluctuation, still keep removing mist efficient about 99%.
Description of drawings
Fig. 1 is a demister unit arrangement schematic diagram of the present utility model;
Fig. 2 ~ Fig. 5 is the demister unit arrangement schematic diagram of the utility model embodiment 1.
The specific embodiment
One device load fluctuation is at 50-120%, if adopt single demister unit, because of this demister design range of load fluctuation is 80-120%, and it is not good to remove mist efficient when 50% and 70% load, less than 99%.
Solution is to adopt 3 demister unit arranged side by side, and as shown in Figure 2, the demister unit numbering is respectively 1
#, 2
#, 3
#, each demister unit is handled load and is respectively 20-30%, 30-40%, 50-60%.Concrete duty is as follows:
When the load of required processing is 80-120%, come into operation 1
#+ 2
#+ 3
#, that is, valve wide open as shown in Figure 2, starts three demister unit simultaneously.
When the load of required processing is the 70-80% load, come into operation 2

Embodiment 2
One device load fluctuation is at 30-120%, if adopt single demister unit, because of this demister design range of load fluctuation is 80-120%, and it is not good to remove mist efficient when 50% and 70% load, less than 99%.
Solution is to adopt 4 demister unit arranged side by side, and the demister unit numbering is respectively 1
#, 2
#, 3
#, 4
#, each demister unit is handled load and is respectively 10-20%, 20-30%, 30-40%, 40-50%.Concrete duty is as follows:
