Description

Technical Field

[0001] This utility model relates to the field of industrial hazardous waste treatment technology, and in particular to a harmless incineration device for industrial hazardous waste. Background Technology

[0002] Industrial hazardous waste refers to waste generated during industrial production processes that possesses hazardous characteristics such as toxicity, corrosivity, flammability, reactivity, or infectivity. Improper handling can cause serious and long-term harm to the ecological environment and human health. Incineration, as a highly efficient and thorough technology for the harmless treatment of industrial hazardous waste, can significantly reduce waste volume and decompose harmful organic substances, making it one of the most widely used treatment methods. The performance of its core equipment, the incineration unit, directly affects the treatment effect and environmental safety.

[0003] However, in practical applications, it has been found that some existing industrial hazardous waste incineration devices have room for improvement in the feeding process. Traditional feeding methods, such as simple gravity feeding or manual addition, are prone to blockages and bridging in the feeding channel due to uneven waste morphology and high moisture content, resulting in discontinuous and uneven feeding. This not only affects the stability of combustion conditions within the incinerator and reduces processing efficiency, but also increases the labor intensity and safety risks for operators due to frequent manual unblocking. Furthermore, an unsealed or uneven feeding process can lead to the escape of harmful gases or dust from the feed inlet, polluting the operating environment. Therefore, achieving a stable, sealed, and automated transport of hazardous waste into the incinerator body has become a key point in improving the practicality and safety of the device. Utility Model Content

[0004] This invention provides an industrial hazardous waste incineration device that features smooth feeding, high combustion efficiency, and good exhaust gas purification. The device effectively solves the problem of feeding blockage through a motor-driven screw feeding mechanism.

[0005] The technical solution adopted by this utility model is as follows: a harmless incineration device for industrial hazardous waste, including an incinerator body, a feeding channel, a water tank, and a purification tank. The feeding channel is connected to the incinerator body through a discharge pipe. A feeding hopper is connected to the top of the feeding channel at the end away from the incinerator body. A motor is fixedly installed on the side of the feeding channel away from the incinerator body. The output end of the motor is provided with a rotating shaft that passes through the side wall of the feeding channel and extends into the inside of the feeding channel. Spiral feeding blades are fixedly sleeved on the rotating shaft. An exhaust pipe that passes through the water tank and is connected to the purification tank is connected to the top of the side of the incinerator body away from the discharge pipe.

[0006] As a further improvement of this utility model, the top of the feed hopper is rotatably connected to a cover plate, and the cover plate is provided with a handle.

[0007] As a further improvement of this utility model, the feeding pipe is inclined, with the lower end of the feeding pipe connected to the main body of the incinerator and the higher end connected to the feeding channel.

[0008] As a further improvement of this utility model, an induced draft fan is provided on one side of the bottom end of the incinerator body, and the output end of the induced draft fan is connected to the incinerator body through an air inlet pipe.

[0009] As a further improvement of this utility model, the connection between the exhaust pipe and the bottom of the water tank is a sealed connection, and the exhaust pipe is spirally coiled inside the water tank.

[0010] As a further improvement of this utility model, the purification box is provided with a first filter layer, a second filter layer and a third filter layer from bottom to top. The first filter layer is an activated carbon adsorption layer, the second filter layer is a glass fiber cotton filter layer, and the third filter layer is a HEPA high-efficiency filter layer.

[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0017] This utility model provides the following: Figure 1-3 The device shown is a harmless incineration device for industrial hazardous waste, including an incinerator body 1, a feeding channel 2, a water tank 3, and a purification tank 4. The feeding channel 2 is connected to the incinerator body 1 through a discharge pipe 5. The top of the feeding channel 2 away from the incinerator body 1 is connected to a feeding hopper 6. A motor 7 is fixedly installed on the side of the feeding channel 2 away from the incinerator body 1. The output end of the motor 7 is provided with a rotating shaft 8 that passes through the side wall of the feeding channel 2 and extends into the inside of the feeding channel 2. Spiral feeding blades 9 are fixedly sleeved on the rotating shaft 8. The top of the side of the incinerator body 1 away from the discharge pipe 5 is connected to an exhaust pipe 10 that passes through the water tank 3 and is connected to the purification tank 4.

[0018] like Figure 1-3 As shown, in this utility model, the top of the feed hopper 6 is rotatably connected to a cover plate 11, and the cover plate 11 is provided with a handle. By setting the cover plate 11, external impurities can be effectively prevented from entering the feed hopper during the feeding process, and harmful gases generated during the incineration process can be prevented from escaping through the feed hopper 6. Operators can conveniently open or close the cover plate 11 through the handle, which improves the convenience of operation and the airtightness of the system.

[0019] like Figure 1-3As shown, the feed pipe 5 in this utility model is inclined. The lower end of the feed pipe 5 is connected to the incinerator body 1, and the higher end is connected to the feed channel 2. This inclined structure design allows the hazardous waste pushed to the end of the feed channel 2 by the spiral feeding blades 9 to slide smoothly into the incinerator body 1 along the feed pipe 5 under its own gravity, reducing the retention of materials during the conveying process and further ensuring the continuity of feeding.

[0020] like Figure 1-3 As shown, in this utility model, an induced draft fan 12 is provided on one side of the bottom end of the incinerator body 1. The output end of the induced draft fan 12 is connected to the incinerator body 1 through an air inlet pipe 13. When the induced draft fan 12 is working, it can draw outside air into the incinerator body 1 through the air inlet pipe 13, providing sufficient oxygen for the combustion of hazardous waste in the incinerator body 1, promoting a more complete and efficient combustion reaction, improving incineration efficiency, and at the same time helping to timely export the high-temperature flue gas generated by incineration to the subsequent treatment stage.

[0021] like Figure 3 As shown, in this utility model, the connection between the exhaust pipe 10 and the bottom end of the water tank 3 is sealed. The exhaust pipe 10 is spirally coiled inside the water tank 3. The sealed connection can prevent the cooling water in the water tank 3 from leaking. The spiral coiled structure significantly increases the contact area and contact time between the exhaust pipe 10 and the cooling water in the water tank 3, so that the high-temperature flue gas can fully exchange heat with the cooling water when passing through the exhaust pipe 10, thereby achieving efficient cooling of the flue gas and preventing the high-temperature flue gas from directly entering the purification box 4 and damaging the filter layer.

[0022] In this invention, the purification chamber 4 is provided with a first filter layer, a second filter layer, and a third filter layer from bottom to top. The first filter layer is an activated carbon adsorption layer, which can effectively adsorb organic pollutants, odors, and some heavy metal ions in the flue gas. The second filter layer is a glass fiber cotton filter layer, which can intercept and filter larger dust particles and impurities that have not been completely adsorbed in the flue gas. The third filter layer is a HEPA high-efficiency filter layer, which can further filter smaller particles in the flue gas to ensure the cleanliness of the emitted gas. The top of the purification chamber 4 is connected to an exhaust pipe 14. The clean gas after multi-layer filtration and purification is discharged into the atmosphere through the exhaust pipe 14, effectively reducing environmental pollution.

[0023] Working Principle: In practical implementation, the operator first opens the cover plate at the top of the feed hopper by hand, puts the industrial hazardous waste to be treated into the feed hopper, and then closes the cover plate to ensure the airtightness of the feeding system. The motor is started, driving the rotating shaft and the spiral feeding blades fixedly sleeved on the rotating shaft to rotate. The hazardous waste in the feed hopper falls into the feeding channel under gravity and is continuously and evenly pushed towards the discharge pipe by the rotating spiral feeding blades. Because a tight pushing space is formed between the spiral feeding blades and the inner wall of the feeding channel, even for waste with high moisture content or uneven shape, blockage or bridging in the feeding channel can be effectively avoided. When the waste is pushed to the end of the feeding channel, it enters the inclined discharge pipe and slides smoothly into the main body of the incinerator under its own gravity. At the same time, the induced draft fan is started, continuously supplying air into the main body of the incinerator through the air inlet pipe, providing sufficient oxygen for the combustion of hazardous waste in the furnace, promoting complete combustion and improving incineration efficiency.

[0024] The high-temperature flue gas generated during incineration is drawn out by an induced draft fan and discharged from the exhaust pipe at the top of the incinerator. The exhaust pipe first enters the bottom of the water tank. Because the exhaust pipe spirals within the water tank and its connection to the tank is sealed, the high-temperature flue gas undergoes thorough heat exchange with the cooling water as it flows through the spiral exhaust pipe, rapidly reducing its temperature and preventing damage to the filter layers in the subsequent purification chamber. The cooled flue gas then enters the purification chamber, passing sequentially through the first filter layer (activated carbon adsorption layer), the second filter layer (glass fiber cotton filter layer), and the third filter layer (HEPA high-efficiency filter layer), arranged from bottom to top. The activated carbon adsorption layer utilizes its abundant pores to efficiently adsorb organic pollutants, odor molecules, and some heavy metal ions from the flue gas. The glass fiber cotton filter layer, with its fine fiber structure, traps and filters larger dust particles and incompletely adsorbed impurities in the flue gas. The HEPA high-efficiency filter layer further filters even the smallest particles in the flue gas, ensuring the cleanliness of the emitted gas. Finally, the clean gas, after undergoing multiple purification processes, is safely released into the atmosphere through the exhaust pipe at the top of the purification chamber. The entire process achieves efficient and safe treatment of hazardous waste from feeding and incineration to exhaust gas purification, effectively ensuring the safety of the operating environment and the surrounding ecological environment.
