The utility model relates to a device which integrates three functions of desulfuration, dedusting and gas force conveying into a whole, not only has little equipment occupation area, less investment, convenient operation and stable operation, but also satisfies the demands of national environment protection on environment and atmosphere pollution discharge standards.
Description
Technical field
The utility model relates to a kind of flue gas desulfur device, particularly about a kind of composite slaked lime desulfurizing device.
Background technology
At present; the improvement that combustion apparatus such as the Industrial Boiler of fire coal and station boiler are discharged the pollutant in the flue gas; it is the object of most countries environmental protection keypoint treatment in the world always; sulfur in smoke particularly; its produced pollution causes the greatest contamination source of environmental destruction especially, has become the task of top priority of various countries' air pollution treatment.Improvement to sulfur dioxide in flue gas, adopt the wet process of FGD technology more than 90%, though it can reach good desulfurized effect, but its dust removing effects is unsatisfactory, simultaneously because it needs bigger fund input and higher water consumption, in the area of some economics of underdevelopment, shortage of water resources, its application is very restricted.Therefore, the flue gas desulfurization technique of little, efficient, the low operating cost of exploitation water consumption is numerous environmentalists' a striving direction always.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides the composite slaked lime desulfurizing device of little, efficient, the low operating cost of a kind of water consumption.
For achieving the above object, the utility model is taked following technical scheme: a kind of composite slaked lime desulfurizing device, it is characterized in that: it comprises a sack cleaner, one calcium hydroxide storage tank, one air conveyor and a blower fan, the gas approach of described sack cleaner is connected with coal-burning boiler by flue, the discharging opening of described calcium hydroxide storage tank connects the charging aperture of described air conveyor, the air inlet of described air conveyor connects described blower fan, and the discharging opening of described air conveyor is connected on the flue near the gas approach front end of described sack cleaner by conveying pipeline; Some steam shower nozzles are set in the flue between the gas approach of described conveying pipeline and sack cleaner.
The revolving valve of one control calcium hydroxide quantity delivered is set between the charging aperture of the discharging opening of described calcium hydroxide storage tank and air conveyor.
The utility model is owing to take above technical scheme, and it has the following advantages: 1, the utility model adopts dry desulfurizing process, only needs a spot of steam in flue gas desulfurization course, thereby has reduced water consumption widely.2, because the utility model adopts the reaction unit of sack cleaner as sweetening process, gaseous sulfur dioxide molecule in the flue gas can not only be directly and calcium hydroxide generation chemical reaction be cured, calcium hydroxide can also be adsorbed on the filter bag surface formation one alkaline film of sack cleaner simultaneously, thereby to the further desulfurization of flue gas, can reach higher desulfuration efficiency, generally can reach more than 80%.3, because the utility model adopts the reaction unit of sack cleaner as sweetening process, solidfied material, calcium hydroxide and the dust in flue gas that flue gas desulfurization produces can be filtered and be concentrated discharge from the ash hole of sack cleaner by sack cleaner, can not produce any secondary pollution and accessory substance.In sum, the utility model is that collection desulfurization, dedusting and strength are carried Trinitarian device, and not only ground, device station area is little, and small investment is easy and simple to handle, stable, and has satisfied the requirement of national environmental protection to environment and air pollution emission standard.
Description of drawings
Fig. 1 is overall structure of the present utility model and process flow diagram
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises a sack cleaner 1, one calcium hydroxide storage tank 2, an air conveyor 3 and a blower fan 4, the gas approach of sack cleaner 1 is connected with coal-burning boiler 6 by flue 5, the discharging opening of calcium hydroxide storage tank 2 connects the charging aperture of air conveyor 3, the air inlet of air conveyor 3 connects blower fan 4, and the discharging opening of air conveyor 3 is connected on the flue 5 near the gas approach front end of sack cleaner 1 by conveying pipeline 7.In the flue 5 between the gas approach of conveying pipeline 7 and sack cleaner 1 some steam shower nozzles 8 are set simultaneously, effect is that mixed flue gas is carried out humidification, thereby can reach the higher desulfuration effect.
In the foregoing description, the revolving valve 9 of a control calcium hydroxide quantity delivered is set between the charging aperture of the discharging opening of calcium hydroxide storage tank 2 and air conveyor 3.
The utility model in use, its sweetening process may further comprise the steps:
1, by air conveyor 3 calcium hydroxide in the calcium hydroxide storage tank 2 is blown in the flue 5, its flue gas with coal-burning boiler 6 is mixed;
2, the steam by shower nozzle 8 ejections carries out humidification to mixed flue gas;
3, the flue gas behind the humidification is blown into sack cleaner 1, direct and the calcium hydroxide generation desulphurization reaction of a sulfur in smoke part, a part is adsorbed on the alkaline film generation desulphurization reaction of the filter bag surface formation of sack cleaner 1 with calcium hydroxide, thereby makes the gaseous sulfur dioxide molecule in the flue gas be cured;
4, clean flue gas enters atmosphere from the gas vent of sack cleaner 1;
5, solidfied material, calcium hydroxide and the dust in flue gas of flue gas desulfurization generation are then filtered by sack cleaner 1 and are concentrated discharge from the ash hole of sack cleaner 1.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
