Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment equipment, in particular to a rotary heat storage incinerator. Background Art

[0002] The regenerative thermal incinerator, also known as the regenerative thermal incinerator (RTO), is a highly efficient waste gas treatment equipment. It consists of a furnace body and valve components.

[0003] The furnace body is divided into a regenerator and a combustion chamber from bottom to top. The regenerator is divided into several equal chambers, each of which is filled with ceramic regenerator materials. When the exhaust gas enters several chambers of the regenerator, it can absorb the heat of the ceramic material to achieve a preheating effect. The preheated exhaust gas enters the combustion chamber for combustion, and the organic pollutants in the exhaust gas are oxidized and decomposed into harmless substances such as carbon dioxide and water. The oxidized high-temperature gas flows through another chamber and is discharged after heat exchange with the ceramic material. The ceramic regenerator material completes the heat storage operation.

[0004] The traditional valve assembly is composed of several groups of switching valves, each of which includes an inlet valve, an outlet valve, and a purge valve. The number of switching valve groups corresponds to the chambers of the heat storage chamber, which is used to control the airflow direction of each chamber so that each chamber can perform heat storage, heat release, and purge operations. The valve components of this structure are numerous and complex, so a solution using a rotary valve as a valve component has emerged, which is a rotary heat storage incinerator.

[0005] However, the thermal incinerator still has defects: If some waste gas containing organic matter is not completely decomposed, dioxins will be produced. Dioxins are very toxic and need to react at high temperature for 2 seconds to be completely decomposed. However, in the existing thermal storage incinerator, the waste gas is preheated by the ceramic material in one chamber and enters the combustion chamber. Thereafter, it is attracted to another chamber for discharge before being fully decomposed. The reaction time does not reach 2 seconds, and some dioxins are discharged.

[0006] Based on the above defects, the prior art proposes to extend the path of the exhaust gas in the combustion chamber to prevent the exhaust gas from entering the combustion chamber and being immediately discharged from another chamber, thereby ensuring the residence time of the exhaust gas in the combustion chamber and avoiding the generation of dioxins.

[0007] Based on this, a rotary thermal storage incinerator that can take this solution into consideration was developed. Summary of the invention

[0008] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a solution: a baffle is arranged in the furnace chamber of the regenerative incinerator to divide the area of ​​the combustion chamber so as to extend the path of the exhaust gas in the combustion chamber.

[0009] Therefore, one object of the present invention is to provide a rotary thermal storage incinerator that can adapt to the above-mentioned solution with baffles.

[0010] The rotary heat storage incinerator proposed in the present invention includes a furnace body, the chamber of the furnace body includes a heat storage layer and a combustion chamber, the heat storage layer is divided into a plurality of fan-shaped areas, the plurality of fan-shaped areas are distributed around the central axis of the chamber, and ceramic fillers are arranged in each fan-shaped area.

[0011] Different from the traditional scheme, the present thermal storage incinerator abandons the rotary valve of the traditional rotary thermal storage incinerator, and is provided with a distribution device, which includes a distribution chamber and a distribution plate, wherein the distribution chamber sequentially forms a plurality of annular chambers from the central axis outward; the distribution plate sequentially forms a plurality of through holes from the central axis outward, and the plurality of through holes are distributed along the circumference of the distribution plate, and the plurality of annular chambers correspond to the plurality of through holes one by one; each annular chamber can be connected with different sector-shaped areas through the corresponding through holes; It also includes a rotating shaft assembly, which includes a rotating shaft connected to the distribution disk, so that when the distribution disk rotates, the same annular chamber can be connected to different sector-shaped areas through corresponding through holes.

[0012] The advantage of such a setting is that no matter how the distribution disk rotates, each annular chamber and the corresponding through hole are always connected, that is, the exhaust gas can always flow between the corresponding annular chamber and the through hole. At the same time, when the distribution disk rotates, the through hole can be connected with different fan-shaped areas, so that the exhaust gas can flow between a certain annular chamber and different fan-shaped areas. Therefore, after some fan-shaped areas have accumulated heat, the annular chamber responsible for air intake can be connected with these fan-shaped areas, so that the exhaust gas can exchange heat with the ceramic materials in these fan-shaped areas, and these fan-shaped areas can release heat; and for the fan-shaped areas that have released heat, they can be connected with the annular chamber responsible for air outlet, so that the exhaust gas after combustion can exchange heat with the ceramic materials in these fan-shaped areas, and these fan-shaped areas can accumulate heat; thus, by setting the annular chamber and the distribution disk, the function of the rotary heat storage incinerator can be realized.

[0013] At the same time, it can be seen in this process that the air intake area and the air outlet area in the combustion chamber are transformed; The distribution plate is driven by a rotating shaft, and the rotation of the distribution plate can be realized by connecting the input end of the rotating shaft to a power device such as a motor. Therefore, if a baffle is set in the combustion chamber, this design scheme can conform to the baffle scheme, extend the rotating shaft into the combustion chamber to connect with the baffle, and the baffle rotates with the rotating shaft, that is, the baffle can also change with the change of the air intake area and the air outlet area of ​​the combustion chamber, thereby extending the travel path of the exhaust gas and ensuring the reaction time of the exhaust gas in the combustion chamber.

[0014] In some examples of the present invention, one end of the rotating shaft extends into the combustion chamber and is connected to an exhaust gas baffle in the combustion chamber. The exhaust gas baffle is composed of baffles arranged at an angle, and the angle covers a plurality of fan-shaped areas.

[0015] The advantage of this arrangement is that the combustion chamber is divided by the baffle, thereby ensuring the reaction time of the exhaust gas.

[0016] In some examples of the present invention, one end of the rotating shaft close to the combustion chamber extends outside the furnace body, and an igniter is installed at this end. The output end of the igniter extends into the combustion chamber and is located within the opening angle formed by the baffle.

[0017] The purpose of such arrangement is that the igniter of a conventional thermal storage incinerator is mounted on the furnace wall and its position is fixed, whereas in the present application, the igniter is mounted on a rotating shaft, and when the rotating shaft rotates, the igniter is driven to rotate, ensuring that the output end of the igniter is always within the opening angle formed by the baffle, i.e., the exhaust gas entering the combustion chamber needs to be ignited.

[0018] In some examples of the present invention, the through holes include exhaust gas inlet through holes, purge through holes and exhaust gas outlet through holes distributed in sequence along the circumference of the distribution plate; the corresponding annular chambers are the exhaust gas inlet cavity, the purge cavity and the exhaust gas outlet cavity respectively.

[0019] The purpose of such arrangement is: the waste gas inlet chamber and the waste gas inlet through hole are used to input the waste gas into the furnace body, the waste gas outlet chamber and the waste gas outlet through hole are used to output the waste gas from the furnace body, and the purge gas chamber and the purge through hole are used to input the purge gas into the furnace body. The function of the purge gas is to purge the waste gas remaining in the ceramic material.

[0020] In some examples of the present invention, the distribution plate includes an upper plate and a lower plate that are integrally formed, and a plurality of fan-shaped recesses are provided on the upper plate corresponding to the fan-shaped areas, and the exhaust gas inlet through hole, the purge through hole and the exhaust gas outlet through hole are all provided on the lower plate, so that the exhaust gas inlet through hole, the purge through hole and the exhaust gas outlet through hole are respectively connected to the corresponding fan-shaped recesses.

[0021] In some examples of the present invention, the distribution chamber includes an outer shell, the upper end of the outer shell is open and connected to the opening at the lower end of the furnace body, the lower end of the outer shell is closed, the distribution plate is placed at one end of the outer shell close to the furnace body, and also includes a plurality of annular wall shells that are sequentially arranged and placed in the outer shell, dividing the inner cavity of the outer shell into a waste gas inlet cavity, a purge air cavity and a waste gas outlet cavity.

[0022] In some examples of the present invention, each annular wall shell is sealed to the distribution plate via a sealing ring and is welded to the outer shell.

[0023] The purpose of such arrangement is to avoid leakage between the cavities.

[0024] In some examples of the present invention, the annular wall shell also divides the inner cavity of the outer shell into a shaft cavity, so that the shaft can pass through the shaft cavity and extend to the outside of the outer shell.

[0025] The purpose of such arrangement is to reserve space for the rotating shaft so that the rotating shaft can extend to the lower end of the entire incinerator to facilitate the connection of power devices such as motors.

[0026] In some examples of the present invention, a frame is provided in the heat storage layer, and the frame includes a first column axis and a plurality of plates distributed circumferentially along the first column axis, one end of each plate is connected to the first column axis, and the other end extends radially along the furnace body until it is connected to the inner wall of the furnace body, thereby dividing the heat storage layer into a plurality of sector-shaped areas.

[0027] In some examples of the present invention, a first column cavity is formed on the first column shaft, so that the rotating shaft can pass through the first column cavity and extend into the combustion chamber.

[0028] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
