Abstract
Eddy flow for desulfuration absorbing tower of the present utility model takes off mist device and belongs to environmental technology field, there is the cavity housing that a top is cylindrical shell, bottom is vertebra shape housing, described cylindrical shell upper side has trapezoidal air inlet, described cylindrical shell end face center is inserted with discharge pipe, the top of described discharge pipe is higher than the end face of described cylindrical shell, the bottom of described discharge pipe flushes substantially with described trapezoidal air inlet lower limb, and described conical shell bottom has sewage draining exit.The utility model structure is simple, utilizes the principle of screw fluid centrifugal sedimentation to be separated by liquid or solid large to gas little for quality and quality, and not only de-mist impurity-eliminating effect is obvious, and is easy to cleaning, ensures the stable operation of system.
Description
Technical field
Eddy flow for desulfuration absorbing tower of the present utility model takes off mist device and belongs to environmental technology field.
Background technology
Wet desulphurization absorption tower, in running, easily produces " mist " that particle diameter is 10-60 micron, and " mist ", not only containing moisture, it is also dissolved with sulfuric acid, sulfate, SO2 etc.If do not properly not settled, staining and heavy corrosion of blower fan, heat exchanger and flue can be caused.Therefore, wet desulfurizing process proposes the requirement of demist to absorption equipment, cleaned gas wanted demist before leaving absorption tower.
Usual absorption tower demisting device adopts two-layer flap demister and three grades of cleaning devices, its operation principle utilizes gravity and inertial impaction effect, when the gas containing mist passes through demister with certain speed, can bump against with demister internal structure, and depend in its surface.The surperficial mist of demister internal structure, the effect through diffusion and gravity can progressively be assembled, and after weight reaches certain level, will separate from demister internal structure.Because demister internal structure is complicated, the easy fouling and clogging in less cleaning position, can directly have influence on wet desulfurization system reliability service continuously.
Summary of the invention
The purpose of this utility model is that proposing a kind of eddy flow takes off mist device, and it utilizes centrifugal sedimentation principle, will have being separated mutually of different densities in non-homogeneous mixture.
The purpose of this utility model is achieved in that the eddy flow for desulfuration absorbing tower takes off mist device, there is the cavity housing that a top is cylindrical shell, bottom is vertebra shape housing, described cylindrical shell upper side has trapezoidal air inlet, described cylindrical shell end face center is inserted with discharge pipe, the top of described discharge pipe is higher than the end face of described cylindrical shell, the bottom of described discharge pipe flushes substantially with described trapezoidal air inlet lower limb, and described conical shell bottom has sewage draining exit.
It is simple that eddy flow for desulfuration absorbing tower of the present utility model takes off mist apparatus structure, the principle of screw fluid centrifugal sedimentation is utilized to be separated by liquid or solid large to gas little for quality and quality, not only de-mist impurity-eliminating effect is obvious, and is easy to cleaning, ensures the stable operation of system.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the structural representation that eddy flow takes off mist device.
Legend: 1. vapor phase stream, 2. discharge pipe, 3. cylindrical shell, 4. liquid fixed double phase flow, 5. conical shell, 6. sewage draining exit, 7. trapezoidal air inlet, 8. flue gas.
Detailed description of the invention: the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, eddy flow for desulfuration absorbing tower takes off mist device, there is the cavity housing that a top is cylindrical shell 3, bottom is vertebra shape housing 5, described cylindrical shell 3 upper side has trapezoidal air inlet 7, described cylindrical shell 3 end face center is inserted with discharge pipe 2, the top of described discharge pipe 2 is higher than the end face of described cylindrical shell 3, and the bottom of described discharge pipe 2 flushes substantially with described trapezoidal air inlet 7 lower limb, and described conical shell 5 bottom has sewage draining exit 6.
During work, under the effect of air-introduced machine, flue gas 8 containing gas-liquid-solid three-phase is tangentially sent in cylindrical shell 3 chamber by trapezoidal air inlet 7, high speed gyration is formed in cylindrical shell 3, produce centrifugal force field, under centrifugal action, wall is thrown in the liquid or solid impurity generation centrifugal sedimentation that quality is larger, form liquid fixed double phase flow 4 under gravity along the downward turn of conical shell 5 inwall, and discharge through sewage draining exit 6; The less gas of quality due to less by centrifugal action, therefore is positioned at cylindrical shell 3 central area, and clean gas flow, with less centrifugal masterpiece spiral rotating motion, forms the low pressure spiral vapor phase stream 1 risen, upwards discharged by discharge pipe 2.So far, the de-mist of flue gas 8 is achieved.
Obviously, above-mentioned explanation of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
