According to the present invention, it uses a deodorant that can effectively remove the odor generated in the constituents or slurry sludge having a water content of 30% or less, and increases the calorific value of solid fuel of coal and / or municipal waste / waste wood / waste tires / waste wood All of the sludges associated with livestock (especially herbivore nutrients and powders, as well as omnivores such as pig meal, poultry, servings, sweets, pressed meals, carcasses and carcasses) that were difficult to use as fuels Fields (milk powder sludge, pig flour sludge, poultry sludge, phosphorus sludge, anaerobic digestion sludge, sludge from livestock wastewater facilities) can be recycled. A method is provided.
1 to 6 are views each showing a manufacturing method A to F which is a process for manufacturing pulverized coal using pulverized powder or pulverized sludge according to an embodiment of the present invention.
Hereinafter, preferred embodiments and experimental examples of the present invention will be described in detail with reference to the accompanying drawings, and detailed description of known functions and configurations that may obscure the gist of the present invention will be omitted.
The high calorific coal powder of the present invention is configured to selectively include pulverized powder, quicklime, deodorant, coal, and solid fuel composed of any one or more selected from pulverized powder or pulverized sludge.
The condensate having a water content of 30% or less is composed of at least one selected from among condensed powder or condensed sludge, and condensed powder or condensed sludge used for recycling is generally used, and the condensed powder or condensed sludge has a moisture content of 80% or more. Using natural drying, electric dehydration, drying equipment, compressed dehydrator or axial powder-liquid separator, crushed powder or crushed sludge having a water content of 30% or less is used as a raw material for high-caloric pulverized coal.
However, unlike herbivore and groin, omnivores such as swine, poultry, and persimmon, or sludges thereof, are not used because of high water content and bad odor.
Accordingly, the present invention is to solve the above problems by producing a moisture content of 30% or less for all the pulverized powder or crushed sludge related to sludge or pulverized sludge, as well as pulverized sludge, pulverized sludge, or pulverized sludge, which was previously used. A high calorie coal is produced.
In other words, in the present invention, any one or more selected from cow flour, pig flour, flour, egg powder, silk powder, pressed powder, ground meal, breeding animal waste, and meat animal waste is used as the livestock sludge. Using any one or more selected from among sludge sludges, sludge sludge, sludge sludge, anaerobic digestion sludge, and sludge produced in livestock wastewater, the crushed sludge or sludge sludge having a moisture content of 30% or less is used (hereafter, sludge sludge or sludge sludge). What consists of the above is called 'condensate'.)
Quicklime (CaO), which is optionally used in the present invention, is a white amorphous material having a high specific gravity (3.2 to 3.4), and when left in air, absorbs moisture and carbon dioxide to become moisture, calcium hydroxide and calcium carbonate, and reacts with water. It produces high heat and has the property of becoming calcium hydroxide.
That is, CaO + H 2 O → Ca (OH) 2 + 15.6 Kcal / mol
Ca (OH) 2 + 2CO 2 ¡Æ Ca (HCO 3 ) 2 + 35.4 Kcal / mol
The present invention utilizes the chemical properties of quicklime to mix the quicklime with the hydrated fraction having a moisture content of 30% or less, thereby removing the moisture of the hydrated powder by exothermic reaction by combining the quicklime with the moisture contained in the hydrated powder. It is possible to cause a stabilization reaction without a separate drying process, it is preferable to include 0 to 20 parts by weight based on 100 parts by weight of the condensate.
This is a problem that the cost is excessively generated when the content of the quicklime exceeds 20 parts by weight.
The deodorant is composed of purified sludge, any one or more of phosphoric acid or sulfuric acid, characterized in that it comprises a dry matter having a water content of 10 to 40%, when the water content is less than 10% is completely powdered when using the product 20 Product loss of ~ 40% occurs, causing civil complaints and work inconvenience due to scattering, and if the moisture content exceeds 40%, high water content reduces deodorization function, difficulty in molding, and reslurry. It is important to use a deodorant containing a dry matter having a water content of 10 to 40%, such as problems occur.
In addition, the dried material is made by mixing any one of 5 to 20 parts by weight of sulfuric acid or phosphoric acid to purified water sludge, 100 parts by weight of purified water sludge, or 100 parts by weight of a mixture of sulfuric acid and phosphoric acid in purified water sludge It is made by mixing 5 to 20 parts by weight with respect to sulfuric acid or phosphoric acid does not necessarily need to use expensive phosphoric acid or sulfuric acid, inexpensive recycled phosphoric acid or sulfuric acid can be used.
When the amount of each sulfuric acid or phosphoric acid or the amount of the mixture of sulfuric acid and phosphoric acid used is less than 5 parts by weight based on 100 parts by weight of purified sludge, the deodorizing effect is affected, which is unsuitable as a deodorant, and when used in excess of 20 parts by weight. While there is no difference in the deodorizing effect, the neutralization process due to the excessive input of acid is required separately, and there is a problem that the manufacturing cost increases, so the content is preferably used in an amount of 5 to 20 parts by weight based on 100 parts by weight of purified sludge.
The deodorant is intended to deodorize harmful gases generated in the condensate, and all gases harmful to the human body are subject to deodorization, preferably deodorizing ammonia and hydrogen sulfide, based on 100 parts by weight of the condensate. It is good to contain 10 to 40 parts by weight.
If the content of the deodorant is less than 10 parts by weight, the deodorizing function is lowered and harmful gases generated in the pulverized product are not deodorized, which causes a significant obstacle to the work. When the content of the deodorant exceeds 40 parts by weight, the deodorizing rate is improved. This is because the problem is that it is insignificant and only additional costs are generated.
On the other hand, in the present invention, the production method B for ripening using quicklime on the axial fraction having a moisture content of 30% or less shows an effective deodorizing effect even without using a deodorant.
In addition, the deodorant may be made of useful microorganisms and water to be mixed in 0.01 ~ 0.1 ml per kg of the dry matter.
Here, the effective microorganisms (EM) are combined with a microorganism selected from photosynthetic bacteria, yeast, actinomycetes, and lactic acid bacteria to coexist symbioticly, play a powerful antioxidant effect and harmless to other living organisms, and have been used for fermentation of food for a long time. .
Such useful microorganisms (EM) are not expected to be synergistic due to the mixing of useful microorganisms (EM) when mixed in less than 0.01ml, and can be expected no further effect when mixed with more than 0.1ml 0.01 ~ 0.1 per kg of the dry matter It is suitable to mix the ml, and the water is suitably mixed 10 to 100 times based on the content of useful microorganisms (EM).
The water is preferably contained together because the useful microorganism (EM) is in contact with water to better exhibit its performance, and the deodorant is preferably composed of the dried product, the useful microorganism, and water.
