Abstract
The utility model discloses a dry type sewage removing system. The dry type sewage removing system comprises a rough dust collector, a sewage removing tower, a bag type dust collector and an activating furnace, wherein the sewage removing tower is connected between the rough dust collector and the bag type dust collector. Guide sheets which are arranged at intervals are arranged on the inner wall at the upper middle part of the sewage removing tower. The activating furnace is a recuperative type rotary heating device which is arranged in an inclined manner, comprises a lime feeding device, an inner barrel and an outer barrel; and a steam or compressed air injecting device is arranged on a connecting pipeline between the activating furnace and the sewage removing tower. The dry-type sewage removing system disclosed by the utility model adopts a two-stage dust collecting method, so that dust collecting efficiency can be improved, the filter area of the bag type dust collector can be reduced; meanwhile, the service life of the bag type dust remover is prolonged, and cost is lowered. An active sewage-removing agent can improve sewage removing effect, and the usage amount of the sewage-removing agent is reduced, so that secondary pollution is reduced and sewage-removing cost is lowered.
Description
Technical field
The present invention relates to a kind of dry type decontamination system, belong to the field of engineering technology such as desulfurization and dedusting.
Background technology
In the combustion process of solid waste or other inferior fuel, can produce a large amount of high dusty gases, and carry SO
2, NO
xwith sour gas such as HCl.Conventional decontamination dust collecting process is often first with wet method or semidry method decontamination, and then electric precipitation or bag-type dusting, to reach the effect of decontamination dedusting.In this process, tend to produce the secondary pollutions such as a large amount of waste water or mud, need consumes resources to carry out after-treatment.And too high dust concentration can strengthen the consumption of soil release agent, increase operating cost.
Summary of the invention
The purpose of this utility model is in order to solve prior art defect, and a kind of dry type decontamination system is provided, and when reaching pollutants such as effectively removing sour gas, heavy metal, reduces the generation of secondary pollution, and reduces energy resource consumption.
The technical solution adopted in the utility model is:
A dry type decontamination system, is characterized in that: described system comprises rough cleaner, decontamination tower, sack cleaner and activation furnace; Described decontamination tower is connected between rough cleaner and sack cleaner; Described decontamination tower top is provided with smoke inlet, and smoke inlet is connected by pipeline with rough cleaner outlet; Described decontamination top of tower is provided with soil release agent entrance, and described activation furnace is connected with the soil release agent entrance of decontamination tower by connecting pipe.
In technique scheme, described decontamination tower middle and upper part inwall is provided with spaced apart flow deflector.Described activation furnace is the dividing wall type rotatable heater being in tilted layout, and comprises lime charging gear, inner core and urceolus; Described connecting pipe is provided with steam or compressed air jetting device.
In technique scheme, described rough cleaner is cyclone dust collectors or multi-tube dust cleaner.
The utility model compared with prior art has the following advantages: adopt the method for two-stage dedusting both can improve efficiency of dust collection, reduce again the filter area of sack cleaner, extended the life-span of sack cleaner simultaneously, reduce costs; Activation soil release agent improves decontamination effect, thereby reduces the generation that soil release agent use amount reduces secondary pollution, reduces decontamination and becomes.

The specific embodiment
Below in conjunction with accompanying drawing, describe a kind of dry type decontamination system provided by the utility model in detail.
As shown in Figure 1, a kind of dry type decontamination system described in the utility model, comprises rough cleaner 1, decontamination tower 2, sack cleaner 3 and activation furnace 4.Described decontamination tower 2 is connected between rough cleaner 1 and sack cleaner 3.
First the flue gas of high dust-laden enters rough cleaner 1, at rough cleaner 1, removes flue dust.Described rough cleaner 1 is cyclone dust collectors or multi-tube dust cleaner, and design efficiency of dust collection is 50%-80%.Through the gas of thick dedusting, the smoke inlet by decontamination tower 2 tops enters decontamination tower 2.Decontamination tower flue gas entrance is connected by pipeline with rough cleaner 1 outlet.
As shown in Figure 2, the dividing wall type rotatable heater of described activation furnace 4 for being in tilted layout, comprises lime charging gear 10, inner core 11 and urceolus 12.Lime enters inner core 11 from lime charging gear 10.Inner core 11 and urceolus 12 are concentric structure.Activator steam passes into the partition of inner core 11 and urceolus 12, and the lime in inner core 11 is carried out to contactless activation, improves the decontamination ability of lime.The connecting pipe 5 that soil release agent after activation is connected by the soil release agent entrance 6 with decontamination tower is delivered to decontamination tower 2.Connecting pipe 5 is provided with steam or compressed air jetting device 8, passes into steam or compressed air the soil release agent after activation is carried and enters decontamination tower.When the flue dust removing containing dioxin, heavy metal, steam or compressed air jetting device 8 are simultaneously as active carbon entrance.
Soil release agent enters decontamination tower 2 from the soil release agent entrance 7 at decontamination tower 2 tops, and the position that enters decontamination tower at soil release agent entrance is provided with umbrella baffler, makes the soil release agent spraying into and carry medium to be umbrella and to spray and form eddy flow.The tower of decontamination simultaneously 2 middle and upper part inwalls are provided with spaced apart flow deflector 8, play a part to turn back and prolong smoke flow process, to improve decontamination efficiency.
The utility model adopts the method for two-stage dedusting both can improve efficiency of dust collection, reduces again the filter area of sack cleaner, has extended the life-span of sack cleaner simultaneously, reduces costs; Activation soil release agent improves decontamination effect, thereby reduces the generation that soil release agent use amount reduces secondary pollution, reduces decontamination cost.
