Description

Circular stocker pyrolysis combustion facility {PYROSIS COMBUST PLANT OF ROUND TYPE STOKER}

The present invention relates to a circular stocker pyrolysis combustion facility, and more particularly, the first floor is a pyrolysis furnace and the second floor is a two-layered cylindrical pyrolysis combustion facility that serves as a gas combustion, and the side and top are in a fan shape. A circular stocker made in the form of a conical plate is installed in the lower part of the pyrolysis furnace by mounting a plurality of stockers with a plurality of combustion air injection holes slightly overlapping and obliquely, and some stockers of the circular stockers can be driven in a circumferential direction at the same time. When the waste is put into the high-temperature pyrolysis furnace by attaching a driving device that can be used and some stockers are installed to be fixed, the driven stocker on the lower circular stocker moves forward and backward on the fixed stocker while stirring the waste on the circular stocker. And pyrolysis, and the generated combustion ash flows down along the slope of the circular stocker and falls to the hopper attached to the lower part of the circular stocker through the cultivation outlet, and then discharged to the outside of the circular stocker pyrolysis combustion facility by the re-feeding device installed under the hopper.

On the other hand, the pyrolysis gas and combustion exhaust gas generated during pyrolysis in the pyrolysis furnace are completely burned in the gas combustion furnace installed above the pyrolysis furnace, thereby increasing combustion efficiency to reduce installation and maintenance costs, and easy repair or replacement in case of failure. It relates to a circular stocker pyrolysis combustion facility.

Recently, various wastes generated in various fields can be recycled as solid fuel such as RPF or RDF, which is not a simple landfill or incineration target as food waste is separated and discharged. There is increasing interest in pyrolysis combustion facilities that can recover and reuse energy such as steam production or power generation. In general, incinerators that directly incinerate waste are used, such as a rotary kiln incinerator, a stoker incinerator, and a fluidized bed incinerator, depending on the method of incineration. For industrial waste incineration that is widely used and has a somewhat high calorific value, rotary cylindrical incinerators are mainly used, and fluid bed incinerators are often used for incineration of wastes with small particles such as sludge.

However, in both the stocker incinerator, the rotary cylindrical incinerator, and the fluidized bed incinerator, incineration is carried out by oxidizing and incineration at high temperature by directly contacting the waste with excess combustion air inside the incinerator. There is a disadvantage in that the amount of combustion exhaust gas generated during incineration is increased by supplying 1.8 to 2.5 times the amount of combustion air.

In order to compensate for this problem, in a pyrolysis combustion facility in which the incinerator body has a two-layer structure, pyrolysis while supplying only 0.4 to 0.6 times the amount of theoretical combustion air required for combustion of waste in the pyrolysis furnace installed on the lower first floor. when the thermal decomposition temperature combustion to maintain only enough 300 ℃ to 600 ℃ a component of carbon (C) component of the wastes not being oxidized to CO ₂ all of the complete combustion is discharged to the pyrolysis gases, such as CO ₂ C, CO, CH ₄ , Complete combustion by resupplying combustion air of about 0.4 to 0.6 times the theoretical combustion air amount from the gas combustion furnace installed on the upper 2nd floor of the pyrolysis gas and maintaining the temperature inside the gas combustion furnace from 900 to 1,100°C. The pyrolysis combustion method is called the pyrolysis combustion method, and at this time, the pyrolysis combustion method has the advantage that the amount of exhaust gas generated by supplying less combustion air is discharged by about 30% to 50% less than the incineration method in which the waste is directly incinerated.

The pyrolysis combustion method is theoretically found to be an eco-friendly combustion method that generates a small amount of exhaust gas, and thus many new technologies that can use the pyrolysis combustion method usefully have been disclosed.

As an example of the pyrolysis combustion technology, in configuring a pyrolysis combustion facility of a two-layer structure, the first floor is a pyrolysis furnace, but the bottom of the pyrolysis furnace is composed of a fixed bed, and a plurality of nozzles are attached vertically to the bottom of the fixed bed. There is a fixed-bed pyrolysis combustion facility that is completed by attaching a number of nozzles so that the spray angle is diagonal to the wall of the pyrolysis furnace.

In the fixed bed pyrolysis combustion facility, the pyrolysis gas generated as the pyrolysis of waste proceeds in the first-floor pyrolysis furnace is re-combusted in the second-floor gas combustion furnace to achieve perfect combustion, but the waste input to the pyrolysis furnace is accumulated in the fixed bed. Because the pyrolysis proceeds in the pyrolysis, the pyrolysis time is prolonged, and the waste located in the middle of the accumulated waste does not pyrolyze because the waste is not stirred inside the pyrolysis furnace, so the loss on ignition increases and it is difficult to automatically discharge the generated combustion ash. There is also a disadvantage in that continuous operation that can continuously discharge combustion ash while continuously inputting waste into the combustion furnace is not possible.

Meanwhile, new technologies proposed to compensate for the shortcomings of the fixed-bed pyrolysis furnace are published in Korean Patent No. 10-1078328 and Korean Patent No. 10-0808140. These technologies are located in the lower part of a long cylindrical pyrolysis furnace. The combustion plate in the form of a rotating conical plate is installed, and a plurality of nozzles are installed in the diagonal direction to supply sufficient combustion air to the combustion plate. When waste falls on the combustion plate, it is pyrolyzed by combustion air supplied from the plurality of nozzles. When the temperature inside the pyrolysis combustion furnace rises, some wastes undergo pyrolysis and are generated as pyrolysis gases such as carbon or carbon monoxide (CO). The long cylindrical pyrolysis combustion furnace is combusted while rotating by the supplied combustion air, and the residence time that the pyrolysis gas stays in the pyrolysis combustion furnace is lengthened, so that the pyrolysis gas can be completely burned, and combustion by the rotation of the combustion plate during pyrolysis combustion The waste that fell on the top of the plate rolls downward along the slope of the conical plate-shaped combustion plate, causing pyrolysis and combustion, and some of the waste is rolled and agitated, and the combustion ash generated during pyrolysis combustion is installed under the combustion plate. It is an excellent technology that enables continuous operation as it is automatically discharged to the outside by pyrolysis combustion by an ash discharge device.

In the above rotary combustion plate pyrolysis combustion, if the input waste is molded waste such as pellets made of wood or plastic, it rolls well on the cone-shaped combustion plate and shows excellent combustion efficiency, but in the case of general waste Even if the combustion plate rotates, the waste is entangled on the combustion plate and rotates only with the combustion plate.Therefore, the upper layer of the accumulated waste is in contact with the combustion air to perform pyrolysis combustion, but the lower layer does not come into contact with the air, so pyrolysis combustion is performed in a state that is not burned. It melts with the high temperature inside the furnace and causes the formation of clinker, and the clinker formed becomes larger and larger as the amount of waste input increases, and eventually it cannot be discharged to the outside by pyrolysis combustion, so the operation of the pyrolysis combustion furnace must be stopped. There is a problem that contributes to the shortening of the life of refractory materials in pyrolysis combustion due to a lot of effort in operation maintenance, such as operation and maintenance, and frequent interruption of operation.

In addition, before the waste is put into the pyrolysis furnace 201, the secondary blower 408 is operated to supply pyrolysis gas combustion air to the connection furnace 301, the gas combustion furnace 401, and the injection rod 406, respectively. It is important to adjust the opening and closing angles of the secondary dampers 410 so that the total amount of combustion air does not become more than 0.5 times the theoretical combustion air amount.

The combustion material generated as the pyrolysis combustion proceeds in the pyrolysis furnace 201 is a driving action in which the driving stocker 512 moves forward and backward, and rides on the slope of the circular stocker 522 in the shape of a conical plate and is located at the bottom of the outer edge of the circular stocker 522. It falls over the installed circular fixing plate 515, but when the driving stocker 512 is driven, it is collected and transported by the re-collecting plate 517 attached to the driving stocker 512, and a plurality of cultivation outlets 516 open through the circular fixing plate 515. ) Through the circular stocker 522 falls to the hopper 601 installed below.

The combustion ash that has fallen into the hopper 601 is rapidly cooled while part of it falls into the cultivation chute 602 submerged in the cooling water, and is then discharged to the outside of the pyrolysis furnace 201 by the cultivation chute 602. The reason why is immersed in the cooling water is that the combustion air supplied to the hopper 601 is not supplied to the pyrolysis furnace 201 through the circular stocker 522, and is discharged to the outside of the hopper 601 through the cultivation chute 602. This is because it has the purpose of keeping airtight with coolant so that it does not occur.

Meanwhile, the combustion exhaust gas generated by pyrolysis and combustion of waste in the pyrolysis furnace 201 and combustion of the pyrolysis gas in the gas combustion furnace 401 is passed through the discharge port 404 attached to the top of the gas combustion furnace 401 to the gas combustion furnace. (401) It is discharged to the outside.

Therefore, the embodiments described above are illustrative in all respects and should be understood as non-limiting, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims and All changes or modified forms derived from the equivalent concept should be construed as being included in the scope of the present invention.
