Industrial waste incineration method and device

The present invention provides the industrial waste incinerator with preheating and reburning functions to completely incinerate all waste including industrial waste at high temperature (1000 ° C.-1400 ° C.) where a large number of metals are melted, and to remove dust and mist. ) Collects harmful gases and heavy metals and discharges them to exhaust gas below environmental standards, and solves industrial waste treatment and uses hot air and hot water heating as waste heat, and also contributes to environmental protection. have.

Waste incineration method and apparatus of the present invention comprises an incinerator, a centrifugal force collector and a scrubber, and give a preheating and recombustion function to the incinerator for burning waste, while maintaining the combustion temperature at a high temperature (1000 ℃ -1400 ℃) pyrolysis combustion And all wastes, including industrial wastes, are completely incinerated, and through the centrifugal dust collector which separates and collects the floating dust (fine particles; dust) in the combustion gas, and the scrubber which contains dust and harmful gas (mist), By exhausting the clean gas below the environmental standard from which heavy metals are removed, it can solve the waste disposal and contribute to the environmental protection, and also obtain the hot air and hot water heating effect by using the waste heat of the waste incinerator.

Conventional incinerators are generally included in incinerators that burn waste (garbage), and in the exhaust gas where waste is burned and exhausted, and wind dust collectors (cyclones) that collect dust, and again collect dust and mist, and exhaust gas temperature. The cleaning dust collector is made to lower.

Such an incinerator includes a gas combustion method of burning wastes using gas as an auxiliary fuel in the combustion method, a liquid combustion method of burning wastes using a liquid fuel as auxiliary fuel, and general waste (waste) waste tires. It is divided into solid combustion method which burns old character waste such as waste plastic, and upstream combustion using auxiliary fuel. It can be divided into upstream combustion method and downstream flow method according to combustion progress.

In addition, the types of incinerators for burning waste in an incinerator are divided into a grate incinerator for burning on the rostol, a bottom incinerator for burning at the bottom, and a furnace incinerator for rotating the incinerator.

All the above incinerators use auxiliary fuel to help burn all waste including general waste, which adds power and energy cost to the waste incineration process. At 800 -1000 ℃, incineration of general waste can emit exhaust gas of environmental standard value.

However, when incineration of industrial wastes, which are mainly made of polymer materials such as waste tires and waste plastics, burning dust is generated due to unburned by the flammable limit at the combustion temperature of 800 -1000 ℃, and complex dust collection equipment is needed. If the waste is incinerated at a combustion temperature of 800 -1000 ° C, hydrogen chloride (HCI), chlorine (Cl ₂ ), hydrogen fluoride (HF), silicon fluoride (SiF ₄ ), nitrogen oxides (NO _x ), and sulfur oxides ( SO ₂ ), harmful gases such as carbon monoxide (CO), dioxins and heavy metals, and harmful substances such as heavy metals are emitted.

In order to meet the emission standards of harmful gases and heavy metals according to environmental standards, complex and expensive dust collection facilities are implemented, and industrial waste incineration facilities are expensive, and incineration auxiliary fuel is used, and the operation cost of waste incinerators is high. will be.

In addition, various incineration facilities are disclosed to improve the problems described above.

For example, in Utility Model Publication No. 96-7915, in the incineration apparatus having a conventional rotary grate with a Notari type incineration method, the rotary grate supports a plurality of grates to smoothly supply air. Arranged at regular intervals by the shape to form an erosion to form a cylindrical shape to be rotated by placing on the roller, the outer end of the grate is developed by the lower end is formed discharge port, the cooling water is injected inside the secondary combustion chamber by a flame filter Disclosed is a high-speed incinerator of the general garbage consisting of a combustion chamber cover to form a

In another example, Korean Patent Laid-Open Publication No. 96-31889, a hopper is installed on an upper portion of a body of an incinerator using auxiliary fuel as a burner to solve a problem of low oxygen supply during combustion of flammable waste. And a blower tube and a combustion chamber are formed, and at the bottom thereof, a recollection chamber via rostol and a conveying screw and a dust collecting chamber via an intake pipe are formed. To work together,

A nozzle is formed in the air chamber formed through the air supply pipe in the grate shaft pipe and the grate force pipe connected thereto. The nozzle is formed and communicates with the coolant chamber formed on one side of the grate shaft and the coolant chamber in the grate. The combustible waste incinerator which prevents the lump of a fire and the fusion of thermoplastic vinyl etc. to the grate is disclosed,

In another example, Korean Patent Laid-Open Publication No. 91-18719 shows that combustible industrial waste is filled in a primary incineration chamber so that it can be double-burned without pollution. Occurs. When the gas exits the safety gas passage and the smoke passes through the primary smoke passage through the smoke passage, it is ignited by the secondary ignition and steered by the air conditioner. There is then disclosed a combustible industrial waste dual combustion incinerator which will be completely combusted in the secondary combustion chamber.

As another example of the combustion method, Korean Utility Model Publication No. 93-1087 describes an ultrasonic vibrator attached to a lower part of an incineration chamber in an electronic incinerator having a single or a plurality of incineration chambers and the incoming dirt to the ultrasonic vibrator. By this first ultrasonic ultrasonic incinerator has been disclosed that consists of a program that is primarily dry, and after the incineration to vibrate the dirt and discharged to the ceramic filter.

However, all of the above incinerators also use auxiliary fuel to help burn all wastes including general waste, which adds power energy consumption and incineration auxiliary fuel costs to waste incineration. Its burning temperature is 800 ℃ -1000 ℃, so it is considered safe for incineration of general waste.In the case of industrial waste incineration, burning is generated due to unburned due to flammable limit, and complex dust collection equipment is needed. When incinerated at the combustion temperature of 800 ℃ -1000 ℃, it is inevitable that harmful gases such as heavy metals and harmful substances such as heavy metals exceed the environmental standards.

Therefore, the facility of the incinerator is simple and economical effect can be achieved by reducing the auxiliary fuel, and the exhaust gas emitted from the industrial waste incinerator can be converted into exhaust gas free of harmful substances such as harmful gases and heavy metals. Therefore, the emergence of waste incineration methods that can contribute to environmental protection is required.

The present invention uses a preheating and reburning means and a radiant heat combustion means in combination with a waste incineration apparatus composed of an incinerator, a centrifugal dust collector and a scrubber to burn pyrolysis while maintaining the combustion temperature at a high temperature (1000 ° C-1400 ° C). It is made to completely burn all combustible waste including industrial waste without auxiliary fuel, and centrifugal force precipitator to separate and collect dust (fine particles; dust) suspended in combustion gas, and to clean harmful gas such as dust and mist and heavy metals. By discharging it to clean gas below the environmental standard through the dust collector, industrial waste treatment can be completely solved by incineration, contributing to environmental protection, and also the hot air and hot water heating effect by using the waste heat of the incinerator.

The present invention uses a combination of preheating and reburning means and radiant heat combustion means in an incinerator for burning waste in an industrial waste incineration method and apparatus so as to realize the object of the above example, while maintaining the combustion temperature at a high temperature (1000 ° C.-1400 ° C.). All combustible wastes, including industrial wastes, are completely incinerated without auxiliary fuel and are highly economical, especially when burned at flammable temperatures of 800 -1000 ° C (HCI), chlorine (Cl ₂ ), hydrogen fluoride ( HF), silicon fluoride (SiF ₄ ), nitrogen oxides (NO _x ), sulfur oxides (SO ₂ ), carbon monoxide (CO), dioxins and other harmful gases and heavy metals, such as the problem of the previous incineration methods and devices By protecting the environment by discharging clean gas below the emission standard and by using the exhaust gas discharged from the incinerator as clean gas, And to supply the hot water to be able to heat the method is characterized in incinerating industrial waste also can be obtained cost-effective and apparatus.

In order to realize the object of the present invention, the furnace body of the incinerator is a hollow preheating passage, and the main wall of the combustion chamber is tripled to form a zigzag inverted preheating passage so that the preheated air is supplied to the combustion chamber so that the combustion temperature of the incinerator is 1000-. By increasing the temperature up to 1400 ℃, industrial wastes composed mainly of polymer materials such as waste tires and waste plastics are completely burned by pyrolysis combustion, and the zigzag reversal of the "U" bulkhead in the exhaust passage exhausted by combustion in the combustion chamber. By connecting the radiant heat combustion unit constituting the passage and re-burning the exhaust gas at the radiant heat 1000-1400 ℃, it is possible to exhaust the exhaust gas from which noxious gases and heavy metals are removed. Can be discharged.

In order to achieve the other object of the present invention, dust and mist in the exhaust gas burned and exhausted in the incinerator and the radiant heat combustion unit collect dust and mist between the centrifugal force dust collector and the scrubber to remove harmful metals and heavy metals. By introducing dust and mist contained in the exhaust gas into the combustion chamber of the incinerator through the dust induction part, it is re-burned in three stages and exhausted to clean air of 500 or less that removes harmful gases and heavy metals through complete combustion, and hot air to the vinyl house. By supplying hot water heating and hot air heating, it contributes to the production of agricultural products.
