Description
Technical field
The utility model relates to exhaust-gas treatment fields, and in particular to a kind of sludge drying exhaust treatment system.
Background technique
With being continuously increased for industrial or agricultural and domestic water, China's water treatment technology is also constantly mature, then produces big
Sludge is measured, in the disposal process of sludge, it is necessary to which drying and other treatment is carried out to sludge.In sludge drying treatment process, sludge
In organic principle can and moisture evaporate together, to generate a large amount of high concentration foul waste gas, these exhaust gas have that moisture percentage is high,
Characteristic of the temperature at 200 DEG C or more mainly includes H2S and NH3, additionally includes a variety of aromatic compounds, halogenated hydrocarbons, sulfur-bearing
The foul gas such as compound, oxygenatedchemicals.
The method of processing exhaust gas is by making exhaust gas decompose at high temperature to waste gas from incinerator, but sometimes simultaneously at present
Not can be removed when water content is larger in exhaust gas, while not can be removed the foul odour in exhaust gas yet, the above problem be this field urgently
Problem to be solved.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of sludge drying exhaust treatment systems.
In order to solve the above-mentioned technical problem, scheme provided by the utility model is: a kind of sludge drying exhaust treatment system,
Including sequentially connected sewage sludge feed system, sludge drying system, deduster, dehydrater, level-one spray column, second level spray column with
And activated carbon adsorption device,
The level-one spray column is used for oxygenolysis exhaust gas,
The second level spray column is for neutralizing exhaust gas.
Further, including spray section in the level-one spray column, the spray section is for spraying Strong oxdiative reagent.
Further, including spray section in the second level spray column, the spray section is for spraying neutralization reagent.
Further, the Strong oxdiative reagent precedence sodium chlorate.
Further, the sludge drying system is sludge dryer, including steam inlet, steam (vapor) outlet and exhaust gas
Outlet, the waste gas outlet are connect with the deduster.
Further, the steam (vapor) outlet is connect with a condensing unit.
Further, the deduster is cyclone dust collectors or bag filter.
Further, the dehydrater is electrostatic dehydrater or condensation dehydrater.
The utility model has the beneficial effects that the application can be used for handling the larger sludge drying exhaust gas of water content, while energy
Effectively remove the peculiar smell and organic matter in removing exhaust gas, exhaust-gas treatment excellent effect.
Detailed description of the invention
Fig. 1 is the overall schematic of the utility model.
Figure label explanation: sewage sludge feed system 1, sludge drying system 2, deduster 3, dehydrater 4, level-one spray column 5,
Second level spray column 6, activated carbon adsorption device 7, condensing unit 8.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1, a kind of sludge drying exhaust treatment system, including sequentially connected sewage sludge feed system 1, sludge dry
Dry systems 2, deduster 3, dehydrater 4, level-one spray column 5, second level spray column 6 and activated carbon adsorption device 7,
Wherein, as shown in Figure 1, sewage sludge feed system 1 can be sludge screw conveyer or sludge lifting machine, pass through sludge
Sludge is delivered in sludge drying system 2 by feed system 1.
As shown in Figure 1, sludge drying system 2 be sludge dryer, specifically, the sludge dryer include steam inlet,
Steam (vapor) outlet and waste gas outlet, the waste gas outlet are connect with the deduster 3, the steam (vapor) outlet and a condensing unit 8
Connection, by high-temperature steam by the way that in steam inlet injection channel sludge dryer, high-temperature gas is discharged by steam (vapor) outlet, high temperature
Steam heats sludge, makes the moisture evaporation in sludge and is discharged by waste gas outlet, wherein steam enters by sludge dryer
To in condensing unit 8, so that liquid water is condensed into, so as to recycle.
Wherein, as shown in Figure 1, level-one spray column 5 is used for oxygenolysis exhaust gas, specifically, level-one spray column 5 includes filler
Section and spray section, exhaust gas are trapped in packing section, and the exhaust gas not being trapped rises to spray section, sprays Strong oxdiative by spray section
Reagent carries out oxidation fan to the harmful substance in exhaust gas, and preferred Strong oxdiative reagent selects sodium hypochlorite, passes through sodium hypochlorite
Most of sour gas and organic substance can effectively be removed by carrying out spray.
As shown in Figure 1, second level spray column 6 is used to neutralize exhaust gas, specifically, second level spray column 6 includes packing section, spray section
With demisting section, second level spray column 6 rushes remaining acidic materials to exhaust gas by injection neutralization reagent and neutralizes, specifically, in
It is sodium hydroxide with reagent.
Wherein, as shown in Figure 1, the deduster 3 is cyclone dust collectors 3 or bag filter 3, the dehydrater 4 is to add
Hydrophone or electrostatic dehydrater 4 are condensed, can remove the moisture in exhaust gas by dehydrater 4, it is preferred that dehydrater 4 can also be with
The connection of one circulating water pool, the moisture of removing can be collected into circulating water pool.
The application is delivered to sludge drying system 2 by 1 sludge of sewage sludge feed system, and passes through sludge drying system 2
Sludge is dried, the particle in exhaust gas is removed by deduster 3 and consolidates object, the moisture in exhaust gas is removed by dehydrater 4, then
By level-one spray column 5 to the peculiar smell and organic matter progress oxygenolysis in exhaust gas, by second level spray column 6 in exhaust gas progress
With, and by activated carbon adsorption device 7 in exhaust gas remaining harmful substance and little particle consolidate object and adsorb, finally obtain nothing
The gas of poison, free from extraneous odour, so as to be emitted into air.
The application can be used for handling the larger sludge drying exhaust gas of water content, while can effectively remove the peculiar smell in removing exhaust gas
And organic matter, exhaust-gas treatment excellent effect.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
