Description

Apparatus for perfect combustion of high density waste water and residual product of wastes using high deusity oxygen}

The present invention relates to a complete combustion of waste incineration and high concentration wastewater incineration apparatus using high concentration oxygen, and more particularly, to realize the complete combustion of the waste incineration plant and to produce high concentration wastewater generated in the waste incineration plant using pure oxygen of 93%. The present invention relates to an incineration apparatus that can burn with high concentration of oxygen to reduce exhaust gas and to reduce incinerator prevention facilities.

In general, at present, the incinerator in Korea's waste incinerator is combusted by injecting external air, so there is nitrogen in the air, so it is difficult to burn and it is very difficult to maintain a high temperature.

In addition, the presence of nitrogen in the air causes the generation of nitrogen oxides (NOx) during combustion and does not maintain a high temperature has been a significant problem in dioxin decomposition.

In addition, wastewater incinerators always have a high concentration of wastewater, which requires the construction of a separate wastewater treatment plant. Also, a high concentration of wastewater is not well treated, and there is a problem in that the operation and management costs are excessively consumed.

The present invention has been made to solve the above problems, the object is to separate the oxygen in the air by burning incineration with a high concentration of oxygen and the air is a mixture of approximately 21% oxygen and 79% nitrogen to separate the oxygen and nitrogen The technology for producing pure oxygen or pure nitrogen is a very advanced technique and has been maintained only for chemical and industrial uses such as fertilizer production. However, in recent years, it is possible to use oxygen or nitrogen of 93% purity as a general purpose rather than an industrial use. It became. This makes it possible to use a change in the adsorption characteristics of the gas by the pressure. In addition, the advent of the so-called Pressure Swing Adsornption (PSA) oxygen generator using the adsorption characteristics of the gas due to the pressure, which incinerated only 93% of pure oxygen when incineration of waste, which is a problem of environmental pollution, using this PSA. In addition, it is to provide a complete combustion and high concentration wastewater incineration apparatus using high concentration oxygen to reduce the exhaust gas and reduce the tailing prevention facility by incineration of high concentration wastewater generated incinerator with 93% pure oxygen.

In order to achieve the above object, the present invention manufactures pure oxygen from an oxygen / nitrogen separation unit, supplies oxygen to an oxygen storage tank and a grate nozzle, and burns the first combustion in the first combustion chamber, and the oxygen burned in the first combustion chamber is secondary. The secondary combustion burner and the pure oxygen are connected to the combustion chamber to combust the gas, and the high concentration wastewater from the incineration site is burned in the rotary kiln type high concentration wastewater incinerator, and the remaining gas from the combustion is connected to the incinerator waste gas to the high concentration wastewater incinerator. This is achieved by providing an incineration apparatus that can burn gas completely.

1 shows the complete combustion of waste incinerator using high concentration oxygen and a high concentration wastewater treatment incineration apparatus according to the present invention, each of which contains a nitrogen storage tank 12 and an oxygen storage tank 14 in an oxygen / nitrogen separation unit 10, respectively. And the oxygen storage tank 14 is connected to the incinerator primary combustion chamber 22 and the grate nozzle 16 where the primary burner 18 is installed, and the incinerator secondary combustion chamber to penetrate the incinerator primary combustion chamber 22. 24) to form a secondary burner 20 in one side of the incinerator secondary combustion chamber (24).

A waste inlet 34 is formed in the incinerator primary combustion chamber 22, a waste outlet 36 is formed in the incinerator primary combustion chamber 22, and an outlet 38 is formed in one side of the incinerator secondary combustion chamber 24. do.

In addition, the oxygen storage tank 14 is also connected to the rotary kiln type high concentration wastewater incinerator 26 in which the wastewater incineration burner 28 is installed, and the wastewater spraying device 30 is installed at the lower side of the high concentration wastewater incinerator 26 and has a high concentration. The incinerator waste gas connection duct 32 is connected to one side of the wastewater incinerator 26 so as to be connected to the incinerator secondary combustion chamber 24.

The operation of the present invention will be described with reference to the above configuration.

The oxygen and nitrogen separation unit 10 is provided with an oxygen and nitrogen production apparatus in which a nitrogen storage tank 12 and an oxygen storage tank 14 are connected to each other to separate nitrogen and oxygen from the oxygen / nitrogen separation unit 10 to obtain nitrogen. Is sent to the nitrogen storage tank 12 and oxygen is sent to the oxygen storage tank 14, and the combustion is connected to the oxygen storage tank 14 and the grate nozzle 16 in the state where 93% of pure oxygen is produced, and the waste inlet 34 When the waste is injected into), it is first burned by the pure oxygen and the primary burner 18 in the incinerator primary combustion chamber 22.

After the primary combustion in the incinerator primary combustion chamber 22, the secondary burner 20 and pure oxygen are connected to the incinerator secondary combustion chamber 24 to secondary combustion of the gas. At this time, since nitrogen oxides such as NO and NO₂ are not generated because they are only burned with pure oxygen without nitrogen, air pollutants are not generated and complete combustion is possible because carbon and pure oxygen, which are main components of the waste, are combined and burned.

In addition, it can decompose NOx, SOx, dioxin, etc. as it can get high temperature heat, so the amount of air pollutant is not significantly reduced and generated. The high concentration wastewater incinerator (26) is installed, and the wastewater injector (30) installed on one side of the high concentration wastewater incinerator (26) is used to inject the pure water into the wastewater incineration burner (28) while burning the hot water, thereby incinerating the high temperature. Can be.

And the remaining gas during combustion is connected to the incinerator secondary combustion chamber 24 through the incinerator waste gas connection duct 28 in communication with the high concentration wastewater incinerator 26, thereby realizing clean combustion completely.

The present invention provides an incineration apparatus that can supply high concentration of oxygen and burn using high concentration of oxygen at an incineration site where environmental pollution is currently emerging, thereby incinerating waste to be completely burned and completely implementing wastewater treatment, thereby reducing environmental pollution. It is a very useful invention that can reduce the equipment cost and operating cost by reducing the incinerator trailing prevention equipment and also reduce the cost of chemicals.
