Wet flue gas desulfurization tower
Technical field
The utility model relates to a kind of wet flue gas desulfurization tower.
Background technology
At Rock coal containing alum roasting process, flue gas need to, by vertical desulfurizing tower processing, have multiple filling layers and Multi-layer sprinkling device in vertical desulfurizing tower, and due to the limitation in height of vertical desulfurizing tower, in the process of smoke treatment, desulfurization is not thorough, causes environmental pollution.
Summary of the invention
For fear of contaminated environment, fully desulfurization, the utility model proposes wet flue gas desulfurization tower.
For this reason, the technical solution adopted in the utility model is as follows: wet flue gas desulfurization tower, comprise vertical tower, in vertical tower, be provided with multiple filling layers and Multi-layer sprinkling device, Multi-layer sprinkling device is connected with the first feeding spraying pump, it is characterized in that: be also provided with horizontal tower, the import of horizontal tower is provided with air-introduced machine, in horizontal tower, be provided with at least 5-10 layer spray equipment, the outlet of horizontal tower is docked with the bottom of vertical tower, and the spray equipment in horizontal tower is connected with the first feeding spraying pump; Below horizontal tower, be provided with wastewater collection pond, wastewater collection pond is for collecting the waste water after spray equipment spray.
Further restriction to technique scheme: be provided with three layers of filler and three layers of spray equipment in vertical tower.
Beneficial effect: the utility model, by increasing horizontal tower and 5-10 layer spray equipment, is convenient to mounting arrangements, has significantly extended the processing distance of flue gas, and desulfurization is more thorough; Compared with prior art, horizontal tower is convenient to layout to the utility model, and the processing distance of flue gas can change arbitrarily, has advantages of small investment, effective.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, further describe the utility model as follows: wet flue gas desulfurization tower, comprise vertical tower 4, the top of vertical tower 4 is floss hole 4a, in vertical tower, be provided with three layers of filler 5 and Multi-layer sprinkling device 6, Multi-layer sprinkling device 6 is connected with the first feeding spraying pump 7; In addition, be also provided with horizontal tower 2, the import of horizontal tower is provided with air-introduced machine, is provided with at least 5-10 layer spray equipment 3 in horizontal tower, and the outlet of horizontal tower 2 is docked with the bottom of vertical tower 4, and the spray equipment 3 in horizontal tower is connected with the second feeding spraying pump 8; Below horizontal tower, be provided with wastewater collection pond 9, wastewater collection pond 9 is for collecting the waste water after spray equipment spray.
As shown in Figure 1, in vertical tower, be provided with three layers of filler and three layers of spray equipment; The utility model does not limit to therewith, under the condition allowing, multiple filling layers and Multi-layer sprinkling device can be set at the height of vertical tower.
As shown in Figure 1, the number of plies of the spray equipment 3 in horizontal tower can change between 5-10 layer.
