Description

Combustion product using waste gypsum and its manufacturing method {solid type fuel by wastes and a method of manufacturing the same}

The present invention relates to a combusted product using waste gypsum and a method for manufacturing the same, and more specifically, waste gypsum and water dehydration and dry food waste and waste coal about 30-50%, respectively, after crushing to a particle size of 100 mesh or less, respectively. 60% by weight, 5-25% by weight of waste coal, 10-40% by weight of food waste, and 2-10% by weight of waste oil, finely crushed loess, elvan, and zeolite Waste coal containing waste gypsum, which pollutes the environment due to industrial development, by kneading water with a mixture of 2 to 6% by weight of additives of water, germanium crushed powder and feldspar crushed into water, The present invention relates to a combusted product using waste gypsum and a method of manufacturing the same, which are manufactured using combusted products to obtain a calorific value of 4500 Kcal / Kg or more during combustion. .

In general, according to the development of the industry, a lot of resources are required, and many resources that do not reach the content in the process of producing them are classified as waste and cannot be used as waste.

However, although coal is called coal, which is generated in the process of digging coal, the coal coal village is large enough to cover the entire area, but it cannot be effectively processed.

Similarly, there are many efforts to dispose of some food waste and waste oil, but only a few areas are being recycled, and the damage caused by waste materials is gradually increasing. There was a problem.

Accordingly, RDF (refuse derived fuel), or waste fuel, which is formed by mixing and combusting flammable waste or combustible material with food waste is proposed and used.However, a certain amount of heat can be mixed by mixing a combustible and a flame retardant that can be burned by themselves. It was not enough technology to fundamentally dispose of waste due to the limitation of waste treatment capacity and excessive production cost.

On the other hand, phosphate fertilizer is mainly made by processing phosphate ore, and when the chemical process is completed, waste gypsum is accumulated as a by-product.

In order to treat phosphate ore, it must be reacted with sulfuric acid and neutralized with calcium oxide, which generates 4.5 million tons of waste gypsum every year.

Waste gypsum can be used for building materials, chemicals and cement subsidiary materials.

Waste gypsum made from phosphate fertilizers has so many impurities that are harmful to the human body such as cadmium and lead.

The neglected waste gypsum melts naturally and flows to the surrounding area when it comes to rain.

Therefore, several methods for recycling waste gypsum have been sought.

As a result, Patent Application No. 10-2001-0044296 dated July 23, 2001 (a cement concrete road paving method and a cement block manufacturing method using waste gypsum) was proposed.

This means that the amount of waste gypsum: 100-1500 kg, cement 100-500 kg, water: water-cement ratio of 35% or less, water reducing agent: 5% or less of cement usage Mixing the cement to produce a slump value of 0-3 cm;

Laying cement cement mixed in the process and compacting the upper portion with 100% or more of the test specimen;

Sprinkling within 1.2 kg per square meter on top of the compacted surface in the process; Cement concrete road paving method using waste gypsum comprising;

Waste gypsum: 100-1500 kg, cement: 100-500 kg, water: water-cement ratio of 35% or less, water reducing agent: 5% or less of cement usage To prepare a cement concrete so that the slump value is 0-3cm;

Inserting the cement concrete mixed in the process into a block mold and pressing and vibrating to remove the mold, thereby forming a block;

The block formed in the above process was cured at 500 ° C. under a condition of humidity of 90% or higher.

Patent application No. 10-2002-0007995 dated February 14, 2002 (Organic fertilizer using ocher, waste gypsum and pig manure, ocher gypsum cement mortar and ocher gypsum brick) was proposed.

This is done by mixing the loess (mountain soil, paddy soil, gutter soil, etc.), waste gypsum and manure (septic tank serving, pig meal, etc.) at an appropriate ratio and roasting it several times (4-6 times) using incineration heat (high temperature) of waste waste.

The large particles are separated and treated by particle size to make plant manure, such as plants or crops, and added to the fertilizer melted water several times in order to further maximize, and further maximize,

In order to maximize the organic fertilizer, the fertilizer is dissolved several times in the melted water can be obtained by repeating the organic fertilizer,

In order to maximize the appearance, it is placed on gypsum powder and repeated several times, and the manure can be obtained.

The fine powder is classified as a sand substitute and mixed with cement to be used for cement mortar for civil construction and for brick making, thereby obtaining high-quality organic fertilizer for plant cultivation, as well as eliminating environmental pollution. And to maximize the waterproof effect.

And Patent Application No. 10-2000-0021131 dated April 20, 2000 (method of manufacturing waste gypsum mortar composition using the waste material and its article) has been proposed,

It is developed so that it can be solidly solidified without cement in powder state obtained by roasting waste gypsum discarded in a large amount at industrial sites or mines at high temperatures, and thus gypsum, loess or sand soil or cement, gangue powder, jade powder, colored pigment or glue powder. It is possible to manufacture prefabricated panels, prefabricated bricks, fire-resistant doors, three-dimensional plywood, or three-dimensional tiles.

In addition, a patent application No. 10-2003-0032603 dated May 22, 2003 (refining method for recycling waste gypsum) has been proposed,

It is a crushing process to put the waste gypsum in the crusher into the crusher to mix with the ball to disintegrate in the form of particles;

A cyclone process in which the crushed waste gypsum particles are introduced into a conventional cyclone apparatus to separate impurities first;

A specific gravity sorting process for separating impurities contained in the waste gypsum in a secondary manner by selecting the waste gypsum from which the impurities are first separated by a wet specific gravity sorter;

Ultrasonic treatment process to separate the heavy metal remaining in the gypsum particles in the form of fine particles by performing a micro-high crushing process by the ultrasonication of 40 ~ 50kHz to the purified gypsum made of the secondary screening;

The separated heavy metal fine particles and purified pure gypsum are composed of a separation screening process that performs an operation screening in a multi-gravity screening machine, so that impurities contained in waste gypsum can be more easily and effectively purified and processed in large quantities. As a result, it is possible to replace the supply and demand of gypsum raw materials, and to reduce the national environmental damage and waste of waste gypsum, which could not be used as an existing resource.

However, according to the conventional recycling method of waste gypsum, the waste gypsum is mixed with other materials to produce mortar or flooring material, but the waste gypsum itself does not eliminate the bad components. There was a problem of being around us.

And, in Korea, about 400 million liters of waste oil is generated a year. Waste oil is mainly recycled using refined methods, resulting in high energy costs. Waste oil purification methods include ion purification, vacuum distillation and high temperature pyrolysis. Ion purification method removes water and sediment from waste oil and removes heavy metals through chemical treatment, and decompression distillation method uses preliminary treatment to remove water and sediment from waste oil by thin film distillation or tower distillation. And heat distillation under vacuum. The high temperature pyrolysis method is a method of obtaining light oil by heating the waste oil at 450 to 500 ° C. to reduce the molecular weight of the polymer by radical reaction.

However, these purification methods consume a lot of energy and require improvement of the process.

Accordingly, the present invention is to solve the above problems, waste gypsum and water dehydration and dry food waste and waste coal about 30 to 50% of the crushed coal to a particle size of less than 100 mesh, respectively, the waste gypsum 40 ~ 60 Ocher crushed, gannet crushed, and zeolite crushed to a weight of 100 mesh while mixing well by weight, 5-25 wt% of waste coal, 10-40 wt% of food waste and 2-10 wt% of waste oil.
