Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, specifically to an organic waste gas incinerator. Background Technology

[0002] An organic waste gas incinerator is an environmentally friendly device that decomposes organic waste gas through high-temperature combustion. It is mainly used in the industrial field. It generates high temperatures by burning auxiliary fuel to oxidize and decompose organic pollutants in the waste gas into harmless substances such as carbon dioxide and water vapor.

[0003] Existing patent document CN220471640U discloses an organic waste gas incinerator, comprising a furnace body, an inlet assembly, an outlet assembly, and a detection assembly. The furnace body has a vertical partition inside, ceramic accumulators on both sides of the partition, and a burner at the top. The inlet assembly is connected to the lower end of the ceramic accumulator on one side of the vertical partition and includes a waste gas inlet pipe inserted into the lower end of the furnace body. The outlet assembly is connected to the lower end of the ceramic accumulator on the other side of the vertical partition and includes an outlet guide hood and an outlet pipe connected to the lower end of the outlet guide hood. The outlet guide hood contains a filter screen, activated carbon, and a curved partition. This invention solves the problems of existing regenerative organic waste gas incinerators, which cannot detect the gas before pressure relief and cannot filter particulate matter generated during combustion.

[0004] Although this device offers many benefits, it still suffers from the following problems: The combustion chamber structure is simple, connecting two chambers only via a connecting pipe, lacking an effective turbulence and mixing mechanism. Uneven mixing of exhaust gas and air easily creates dead zones, leading to low combustion efficiency and wasted heat energy, resulting in increased auxiliary fuel consumption. Secondly, the first and second dispersion plates in the intake shroud have inclined through-holes, intended to increase the contact area between exhaust gas and the ceramic accumulator. However, these inclined through-holes may cause uneven airflow, increasing local resistance and affecting preheating efficiency. Furthermore, the exhaust assembly uses curved baffles and activated carbon to adsorb particulate matter. While the curved baffles increase the airflow path, they easily accumulate particulate matter, leading to increased pressure drop and frequent blockages. Utility Model Content

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of organic waste gas incinerator achieves "staged tangential air supply" by setting the first and second air supply holes tangential to the furnace body and making the bottom diameter smaller than the top diameter. The high-speed airflow at the bottom forms an effective air curtain at the bottom of the combustion chamber, preventing unburned waste gas from short-circuiting; the high-flow airflow at the top ensures complete combustion. Both mix with the spirally entering preheated waste gas and work in conjunction with the wave-shaped conical baffle to form a strong and complex double-vortex flow field in the combustion chamber, greatly improving the mixing efficiency of waste gas, combustion air, and flame, ensuring that organic molecules are completely decomposed, and significantly improving purification efficiency. The combined structure of the refractory layer and the insulation layer effectively reduces heat loss from the furnace body, improves thermal efficiency, and reduces operating energy consumption. At the same time, the robust refractory layer ensures the safety and service life of the furnace body under long-term high temperatures, while the insulation layer keeps the outer wall temperature of the furnace body within a safe range, avoiding operational risks.

[0021] This type of organic waste gas incinerator combines spiral guide vanes and a rotatable blade disk in the air intake assembly to transform linear airflow into a rotating, rising, uniform airflow. This significantly increases the contact area and contact time between the waste gas and the heat accumulator, achieving more thorough preheating and laying a solid foundation for subsequent efficient combustion. Simultaneously, the rotating motion provides a degree of self-cleaning, preventing particulate matter accumulation. The V-shaped fine filter and dust collection ramp in the exhaust assembly achieve a large filtration area and smooth ash collection within a limited space. Combined with a pull-out sliding frame design, cleaning and replacing the filter becomes exceptionally simple and quick, significantly reducing maintenance costs and time. Furthermore, the integrated pressure gauge and temperature gauge on the exhaust pipe allow for real-time monitoring of the system status, enabling predictive maintenance based on the mechanical structure and ensuring continuous compliance with emission standards.

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] This utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of an embodiment of an organic waste gas incinerator, including:

[0036] Please see Figures 1-6This embodiment of an organic waste gas incinerator includes an incineration assembly 100, which includes a furnace body 110. A burner 180 is bolted to the top of the furnace body 110, and a baffle 170 is bolted to the bottom of the burner 180. Multiple air supply holes 150 and 160 are provided on the outer circumference of the furnace body 110. The air supply holes 150 and 160 provide combustion air to the combustion chamber. The layered design enables graded air distribution and optimizes combustion efficiency. A baffle 140 is welded to the bottom of the inner cavity of the furnace body 110. An air intake assembly is provided at the bottom of the furnace body 110, including an air intake pipe 210. An air intake hood 220 is welded to the top of the air intake pipe 210 to guide and expand the cross-section of the waste gas flow. Multiple guide vanes 230 are welded to the inner circumference of the air intake hood 220 to impart initial rotational momentum to the waste gas, causing it to form a vortex. A mounting bracket 240 is bolted to the inner circumference of the hood 220. A blade disk 250 is rotatably connected to the top of the mounting bracket 240. This disk rotates under the impact of airflow to disperse and centrifugally eject the exhaust gas, achieving uniform distribution. A heat accumulator 260 is bolted to the top of the hood 220. The heat accumulator 260 is a ceramic heat accumulator used to recover the heat from the high-temperature purified flue gas and preheat the incoming low-temperature exhaust gas, significantly reducing system fuel consumption. An exhaust assembly 300 is installed at the bottom of the furnace body 110. The exhaust assembly 300 includes an exhaust pipe 310. A heat accumulator is bolted to the top of the exhaust pipe 310. A coarse filter screen 330 is bolted to the inner wall of the exhaust pipe 310. A detachable filter plate 340 is bolted to the outer wall of the exhaust pipe 310. A fan 370 is bolted to the bottom of the exhaust pipe 310. An exhaust pipe 380 is bolted to the output end of the fan 370.

[0037] It is worth noting that, in order to improve the combustion effect, specifically, the inner circumference of the furnace body 110 is covered with a heat insulation layer 120, which is made of ceramic fiber cotton and is used for heat insulation to reduce heat loss. The inner circumference of the heat insulation layer 120 is covered with a refractory layer 130, which is made of high alumina castable and is used to directly contact the high-temperature flame to protect the furnace body steel plate from being burned. Both the first air inlet 150 and the second air inlet 160 penetrate the heat insulation layer 120 and the refractory layer 130. The opening of the first air inlet 150 and the second air inlet 160 is tangent to the outer circumference of the furnace body 110, and the diameter of the first air inlet 150 is smaller than the diameter of the second air inlet 160.

[0038] Next, in order to improve the turbulence effect of the spoiler 170, specifically, the outer circumference of the spoiler 170 is a conical structure and the outer circumference of the spoiler 170 is a wave-shaped structure. The wave-shaped surface can greatly disrupt the airflow boundary layer, generate a large number of tiny eddies and recirculation zones, thereby violently disturbing the airflow and effectively prolonging the residence time of flue gas in the high-temperature zone, providing more sufficient reaction time for the complete decomposition of pollutants.

[0039] Meanwhile, to enhance the preheating effect, the guide vane 230 has a spiral structure, which can transform the linearly entering exhaust gas into a rotating and rising vortex airflow. This not only increases the contact area and contact time between the exhaust gas and the heat storage body, improving the preheating effect, but also the intake shroud 220 has a conical structure. The conical structure can achieve a smooth transition of the airflow cross section and uniform flow velocity changes, which helps to reduce local vortices and pressure loss, making the airflow more stable.

[0040] Furthermore, to facilitate the installation of other structures of the exhaust assembly 310, specifically, the exhaust pipe 310 has a square structure, which has a high space utilization rate and is more convenient for processing, manufacturing and drilling. A pressure gauge 350 is fixedly connected to the outer wall of the exhaust pipe 310 by bolts for measuring the pressure of the exhaust pipe 310. A thermometer 360 is fixedly connected to the outer wall of the exhaust pipe 310 by bolts for measuring the temperature of the exhaust pipe 310. Multiple threaded blind holes 311 are opened on the outer wall of the exhaust pipe 310.

[0041] It is worth noting that, for ease of maintenance, the detachable filter plate 340 specifically includes a detachable sliding frame 341. The top of the detachable sliding frame 341 has multiple clearance grooves, and the outer wall of the detachable sliding frame 341 has multiple threaded through holes 344. The inner wall of the detachable sliding frame 341 is fixedly connected to a fine filter screen 342 by bolts. The fine filter screen 342 has a V-shaped structure. Under the same projected area, the V-shaped structure provides a much larger effective filtration area than the flat filter screen. At the same time, dust is not easy to adhere to the V-shaped slope and can easily slide down the slope to the dust collection slope under the action of gravity, which has a certain self-cleaning ability and delays clogging. The inner wall of the detachable sliding frame 341 is fixedly connected to a dust collection slope 343 by bolts. The inclined design makes it easy to collect the dust falling from the V-shaped filter screen and guide it to a specific area to avoid dust accumulation at the bottom of the filter unit and facilitate centralized cleaning.

[0042] Finally, to protect the vent pipe 380, specifically, a pressure relief pipe 390 is integrally formed on the outer circumference of the vent pipe 380, and a pressure relief valve 391 is movably connected to the outer circumference of the pressure relief pipe 390. The pressure relief pipe 390 and the pressure relief valve 391 are important safety devices. When the system pressure rises abnormally, the pressure relief valve 391 is opened to release pressure and prevent equipment damage.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-6 The specific usage process of an organic waste gas incinerator according to this embodiment is as follows:

[0045] 1. Turn on the burner 180 to preheat the combustion assembly 100. At the same time, start the fan 370 in the exhaust assembly 300 to create a negative pressure in the furnace. Measure the temperature with an external thermometer. After the combustion chamber temperature rises to the set operating temperature, proceed to the next step.

[0046] 2: Organic waste gas enters through the inlet pipe 210, is evenly dispersed by the spiral guide vane 230 and the rotating blade disk 250, and is preheated by passing through the heat accumulator 260. Then it enters the combustion chamber, where the waste gas is completely burned under the action of the tangentially supplied air and the baffle 170. The high-temperature purified gas passes over the top of the partition 140 and enters the exhaust side. It first recovers heat through the heat accumulator 320, and then passes through the coarse filter 330 and the V-shaped fine filter 342 in the detachable filter plate 340 for filtration. Finally, the clean gas is discharged by the fan 370 through the outlet pipe 380. The operator can monitor the operating status by observing the readings of the pressure gauge 350 and the thermometer 360.

[0047] 3. When the pressure gauge 350 shows an increase in differential pressure or after a certain operating cycle, perform maintenance. After shutting down the system and allowing it to cool, pull out the removable filter plate 340 from the side of the exhaust pipe 310, clean the accumulated dust on the V-shaped fine filter screen 342 and the dust collection inclined plate 343, and reinstall them after cleaning. The pressure relief valve 391 can be opened periodically to check whether its function is normal.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
