Description

{Solidification apparatus for sewage sludge}

The present invention relates to a sewage sludge solidifying apparatus for solidifying sewage sludge (hereinafter referred to as 'sludge') discharged from a sewage treatment plant to utilize it as a resource such as alternative fuel, agricultural material or industrial material, A first stirring mixer and a second stirring mixer are provided in an inner space of the chamber for receiving the sludge and the sludge, and the sludge and quicklime introduced into the inner space of the chamber through the sludge inlet and the quicklime inlet, Mixing the sludge and the quicklime with the primary mixing mixer to mix the sludge and the quicklime with the second mixing mixer provided at the lower part of the internal space of the chamber, To sterilize harmful bacteria and to solidify the sludge.

The amount of sludge including wastewater sludge, swine wastewater sludge, sludge sludge, process sludge and other organic substances generated in the sewage sludge or wastewater treatment plant generated at the present sewage treatment plant is increasing day by day.

Under such circumstances, the sludge is largely treated in the form of onshore landfill, ocean dumping, incineration or fueling, and in particular, many techniques for treating sludge as solid fuel have been developed.

That is, in recent years, attempts and researches on waste resources such as sewage sludge have been carried out in various forms, and as a part thereof, there has been proposed a method of reducing sewage sludge to soil, utilizing it as building material, decomposing effective ingredients, (RDF) is a method of reusing sewage sludge into pellets, cube, and briquette to produce coal or coal. Gas, and petroleum. It has the advantage of being able to collect sludge treatment effect and resource recycling effect at the same time.

On the other hand, sewage sludge has various components depending on the source and regional characteristics, but 70 ~ 85wt% is moisture, and the remainder is combustible and ash, and 10 ~ 14wt% of total amount is combusted. It is reported that the heating value of dry solids is 3000 ~ 5000kcal / kg-waste and does not exceed the environmental standard of CO, SOx, and NOx during complete combustion, and thus it has value as an alternative fuel.

However, because sewage sludge is moisture of 70 ~ 85 wt%, a process for removing moisture is essential for use as fuel, and the water removal process occupies 30 ~ 40% The efficiency of the water removal process is crucial to the production of solid fuel in sewage sludge because it has a decisive influence on productivity and production cost of sludge solid fuel.

The following is a representative prior art technique for solidifying sewage sludge.

Korean Patent Registration No. 10-1481947 discloses a solid fuel production apparatus using a sludge, a manufacturing method thereof, and a solid fuel using the sludge, comprising: a sludge storage tank for storing sludge; A primary dryer for lowering the water content of the sludge contained in the sludge storage tank; A molding machine including at least one pair of drums rotating at a distance from each other to form a sludge dried in the first drier; A mold releasing agent supply unit for supplying a releasing agent to the pair of drums so that the sludge does not stick to the drum; And a second drier for lowering the water content of the sludge formed in the molding machine to 10% or less, and a solid fuel using the sludge-producing apparatus.

In addition, in the above-mentioned prior art, the molding machine is disposed between the first and second drying, the sludge introduced into the molding machine is finely crushed to solidify the mold, and the mold release agent is provided in the process so that the sludge does not adhere to the molding machine, Thereby realizing an economical and excellent solid fuel production.

However, since the conventional art requires excessive energy to remove moisture contained in the sludge, there is a need for continuous research and development for solving the problem.

Korean Registered Patent No. 10-1582844 (December 30, 2015) Korean Registered Patent No. 10-1481947 (June 1, 2015) Korean Registered Patent No. 10-1433141 (Aug. 18, 2014) Korean Registered Patent No. 10-0914993 (Aug. 25, 2009)

The present invention relates to a sewage sludge solidifying apparatus for solving problems associated with prior art sewage sludge solidifying apparatuses. In the conventional sewage sludge solidifying apparatus, only a stirring screw is provided below an inner space of a chamber for receiving sludge and quicklime. Therefore, there is a problem that the mixing property is insufficient and the reaction (digestion reaction) between moisture contained in the sludge and the quicklime and the hydrolysis reactivity of the organic material contained in the sludge are inferior;

As a result, since the digestion reaction rate of quicklime is slowed, the solidification treatment time of the sludge takes a long time and the solidification rate of the sludge is lowered;

In addition, since the temperature of the reaction heat generated during the digestion reaction of quicklime is low, there is a problem that the demolition and deodorization of the noxious bacteria contained in the sludge are inferior, and the main object thereof is to provide a solution thereof.

The present invention has been made to solve the above-

A chamber in which a sludge inlet for receiving the sludge and a quicklime inlet for receiving the quicklime are formed adjacently to the upper portion and a solids discharge port through which the solids are discharged is formed; A first agitation mixing member provided in an inner space of the chamber corresponding to the sludge inlet and the bottom of the quicklime inlet and mixing the sludge charged into the inner space with quicklime to form a mixture; And a second agitation mixing member, which is composed of at least one agitation screw located at a lower portion of the internal space of the chamber, for re-agglomerating the mixture dropped in the first agitation mixing member to produce a solid material, We present a solidification device.

In the sewage sludge solidifying device according to the present invention as described above, the sludge injected into the internal space of the chamber through the sludge inlet and the quicklime inlet is primarily mixed with the quicklime as the first stirring and mixing member, Since the second mixing can be performed with the second mixing mixer, it is possible to obtain an advantageous effect of mixing the sludge with the quicklime;

As a result, the digestion reactivity between the water contained in the sludge and the quicklime is improved, the solidification treatment time of the sludge is shortened, and the solidification rate of the sludge is improved;

Further, the reactivity between the quicklime and the water is improved, and the temperature of the heat of reaction generated in the digestion reaction of the quicklime can be increased, and the demeritiveness and deodorization of the harmful bacteria can be improved.
