Abstract
The utility model relates to a combined type wet flue water and mist removal device, which is suitable for flue gas treatment of a wet two-tower desulfurization system and belongs to an environment protection equipment type. The device consists of a concentrating tower, a desulfurizing tower, a middle flue, a first-level dehydrator and a second-level demister, wherein the first-level dehydrator and the second-level demister are arranged in the middle flue; the first-level dehydrator is arranged at the connecting part of the concentrating tower and the middle flue; the second-level demister is arranged at the middle part of the middle flue. According to the combined type wet flue water and mist removal device, the traditional wet flue demisting way is changed, liquid drops in flue gas are subjected to a grading removal mode that water is firstly removed and mist is then removed, and removal and backflow of most of the liquid drops taken by the treated flue gas are realized; the impact of airflow to the demister is relieved due to the arrangement of the dehydrator, and the probabilities of blockage and collapse of the demister are reduced. The combined type wet flue water and mist removal device has the advantages that the design is reasonable, the mounting and maintenance are convenient, the removal efficiency of the liquid drops is high, the repair cycle of the desulfurization system is prolonged, the non-planned halt times are reduced, and the synchronous rate of the desulfurization system is increased.
Description
Technical field
The utility model relates to the wet flue of a kind of combined type demister that dewaters, and the flue gas that is applicable to wet type double tower desulphurization system is processed, and belongs to environmental protection equipment class.
Background technology
In wet type double tower desulphurization system, flue gas is introduced into after concentration tower, then enters in desulfurizing tower, flue in the middle of being provided with between Liang Ta, and be provided with demister, stop that the water droplet in tyre flue gas enters desulfurizing tower.But in actual motion, because slurries dustiness in concentration tower is high, proportion is also relatively high.Regular generation demister stops up and collapses, and when serious, there will be water removal effect poor.Time between overhauls(TBO) that has shortened desulphurization system of these situations and increased the number of times of non-programmed halt, badly influence the sync rates of desulphurization system operation.
Summary of the invention
For the problem of above-mentioned existence, the purpose of this utility model is to solve wet flue gas when middle flue enters desulfurizing tower, realizes and to remove and be back to concentration tower carrying slurries in flue gas.The oneself that can meet equipment itself simultaneously rinses and protection.Thereby the long-term stability of implement device operation.
To achieve these goals, the utility model solution is: the wet flue of the combined type demister that dewaters, include the middle flue of concentration tower, desulfurizing tower and connection concentration tower and desulfurizing tower, in middle flue, be provided with one-level dehydrater and secondary demister, one-level dehydrater is positioned at the junction of concentration tower and middle flue, the middle part of flue in the middle of secondary demister is positioned at.
Described one-level dehydrater is arranged and is formed by 1 ~ 2 gear water column.
Owing to adopting technique scheme, by the junction at concentration tower and middle flue, dehydrater is installed, the scheme of demister is set in the middle part of middle flue, it has changed conventional wet flue gas demister pattern, the mode that after drop in flue gas has been carried out first dewatering, the classification of demist removes, realized the backflow that removes of the outer guttiferous overwhelming majority of smoke treatment, the impact of air-flow to demister alleviated in arranging of dehydrater, reduced the obstruction of demister and the probability collapsing.
The utility model is reasonable in design, convenient for installation and maintenance, and drop removal efficiency is high, has extended the desulphurization system time between overhauls(TBO), has reduced non-programmed halt number of times, has improved the sync rates of desulphurization system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See accompanying drawing
The wet flue of the combined type demister that dewaters, described device consists of concentration tower 1, desulfurizing tower 4, middle flue 5, one-level dehydrater 2 and secondary demister 3.Middle flue 5 two ends are connected with desulfurizing tower 4 with concentration tower 1 respectively, in middle flue 5, be provided with one-level dehydrater 2 and secondary demister 3, one-level dehydrater 2 is positioned at the junction of concentration tower 1 and middle flue 5, the middle part of flue 5 in the middle of secondary demister 3 is positioned at, described one-level dehydrater 2 can adopt by 1 ~ 2 gear water column and arrange and form.
Dust-laden sulfur-bearing wet flue gas from concentration tower 1 out after, enter in the middle of flue 5, successively with one-level dehydrater 2, after secondary demister 3 meets, finally enter in desulfurizing tower 4.Under airflow function, in the middle of entering, the wet flue gas of flue 5 carries a large amount of slurries and water droplet.When first flue gas meets with one-level dehydrater 2, most of slurries are blocked backflow, and wet flue gas is by again turbulent uniform simultaneously.Dewatered uniform rear flue gas and secondary demister 3 meets, under the effect of secondary demister 3, diameter is all departed from and is refluxed at the above water droplet of 40um, and secondary demister 3 is equipped with wash tub pipe, it is carried out to periodicity and rinse, avoid the obstruction of demist module and collapse.This device carries out classification to drop in flue gas and removes, and one-level dehydrater 2 removes bulky grain water droplet, and uniform air-flow, and secondary demister 3 is responsible for removing small particle diameter water smoke and is dripped.
