Description

Technical Field

[0001] This invention relates to the field of laboratory waste liquid treatment technology, and in particular to a multi-thermal core temperature control coupled laboratory waste liquid treatment equipment. Background Technology

[0002] Laboratory waste liquids, especially organic waste liquids, are generated from experimental research in scientific research institutions, scientific research and teaching in higher education institutions, and daily medical processes in hospitals. These waste liquids have complex and variable compositions, high levels of impurities such as heavy metals and particulate matter, and small production volumes. The main method for the disposal of organic waste liquids is incineration, which minimizes waste volume.

[0003] Currently, the treatment of laboratory organic waste liquids largely relies on fossil fuels, gaseous fuels, or liquid fuels as combustion energy. However, the inherent characteristics of laboratory organic waste liquids present several challenges with traditional treatment methods. Firstly, laboratory organic waste liquids generally have low calorific value, leading to energy waste when using traditional high-energy-density fossil fuels, gaseous fuels, or liquid fuels for auxiliary treatment. Furthermore, the small and intermittent nature of waste liquid generation necessitates frequent equipment start-ups and shutdowns, requiring significant fuel consumption for preheating equipment during startup, thus significantly increasing energy costs. Secondly, traditional fuels such as natural gas and diesel pose risks of flammability, explosiveness, leakage, and poisoning during storage, especially exacerbated by the confined space of a laboratory. Finally, during combustion, if the complex composition of the waste liquid leads to incomplete combustion... It may also produce toxic gases such as carbon monoxide, threatening the safety of operators. Furthermore, due to the complex and variable composition of the waste liquid, which includes hydrocarbons, pesticides, phenols, and other organic compounds, traditional combustion methods make it difficult to precisely control the temperature. Insufficient temperature will lead to incomplete decomposition of harmful substances, while excessive temperature may produce additional pollutants such as nitrogen oxides, increasing the difficulty of subsequent exhaust gas treatment. Secondly, the combustion of traditional fuels will produce a large amount of carbon dioxide, exacerbating carbon emissions. At the same time, the nitrogen oxides, sulfides, and unburned organic compounds produced by the combustion of waste liquid further complicate the composition of the exhaust gas, requiring complex exhaust gas purification equipment. This not only increases equipment costs but also makes the treatment process cumbersome and inefficient. Therefore, this application provides a multi-thermal core temperature control coupled laboratory waste liquid treatment equipment to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a multi-thermal core temperature control coupled laboratory waste liquid treatment equipment. By setting up an electric heating mechanism, it can heat the water or low-boiling-point organic matter in the waste liquid to evaporate. At the same time, the high temperature decomposes harmful substances in the organic waste liquid, such as hydrocarbons, pesticides, and phenols, into inorganic substances such as CO2 and H2O. It can provide sufficient heat to the waste liquid to make it completely evaporate. The above settings can solve the problem of the poor performance of fossil, gaseous or liquid fuels as combustion energy.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A multi-thermal core temperature-controlled coupled laboratory waste liquid disposal device includes a waste liquid treatment equipment body, a base installed at the bottom of the waste liquid treatment equipment body, an insulation door installed on the waste liquid treatment equipment body, a waste liquid inlet at the top of the waste liquid treatment equipment body, a denitrification agent nozzle on the side of the waste liquid treatment equipment body near the waste liquid inlet, a tail gas outlet at the bottom of the waste liquid treatment equipment body, and an ash collection port at the bottom of the waste liquid treatment equipment body; an electric heating mechanism for treating laboratory waste liquid by using electrical energy to generate heat, the electric heating mechanism being connected to the waste liquid treatment equipment body; and a mixing mechanism for uniformly mixing the heat generated by the electric heating mechanism within the working space, the mixing mechanism being connected to the electric heating mechanism.

[0007] Optionally, the electric heating mechanism includes an outer furnace chamber installed inside the main body of the waste liquid treatment equipment, an inner furnace chamber installed inside the main body of the waste liquid treatment equipment, a mixing section at the top of the main body of the waste liquid treatment equipment, a combustion section at the bottom of the mixing section, a burnout section at the bottom of the combustion section, an insulation layer installed on the outer wall of the main body of the waste liquid treatment equipment, a first heater installed inside the outer furnace chamber, a second heater installed inside the inner furnace chamber, a middle furnace chamber formed between the outer furnace chamber and the inner furnace chamber, and a thermocouple installed on one side of the main body of the waste liquid treatment equipment.

[0008] Optionally, the mixing mechanism includes mounting frames installed at the top and bottom of the inner furnace, blades are equidistantly mounted on the outer wall of the inner furnace, a connecting frame is fixedly connected to the bottom of the inner furnace, a toothed ring is fixedly connected to the bottom of the connecting frame, and a drive assembly is installed on one side of the combustion section.

[0009] Optionally, the connecting frame is an arc-shaped structure that protrudes away from the center of the main body of the waste liquid treatment equipment, and a groove is provided at the bottom of the connecting frame.

[0010] Optionally, a scraping mechanism is installed inside the ash discharge port. The scraping mechanism includes a first frame installed at the bottom of the toothed ring, a third frame fixedly connected to the top and bottom of the first frame, and a second frame fixedly connected to the top of the first frame.

[0011] Optionally, a fourth frame is fixedly connected to the bottom of the first frame, a limit rod is installed at the bottom of the ash discharge port, and a first slot adapted to the shape of the limit rod is provided on the fourth frame.

[0012] Optionally, the fourth frame is made of plastic, and a weakening part is provided on the side of the fourth frame away from the ash discharge port.

[0013] Optionally, a second slot is provided at the bottom of the ash discharge port, and a third slot is provided at the bottom of the ash discharge port.

[0014] Optionally, the cross-section of the fourth frame is square, and the cross-section of the limiting rod is L-shaped.

[0015] Optionally, a first limiting groove is provided at the bottom of the ash discharge port, and a second limiting groove is provided at the bottom of the ash discharge port.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up an electric heating mechanism, the water or low-boiling-point organic matter in the waste liquid can be evaporated. At the same time, the high temperature decomposes harmful substances in the organic waste liquid, such as hydrocarbons, pesticides, and phenols, into inorganic substances such as CO2 and H2O. This provides sufficient heat to the waste liquid, allowing it to evaporate completely. Compared with treatment methods that use fossil fuels, gaseous or liquid fuels as combustion energy, electric heating technology does not require fuel storage and has the characteristics of being ready to use immediately and having high temperature control accuracy. It is safer and more practical.

[0018] The heating mechanism comprises an outer furnace and an inner furnace. The outer furnace provides auxiliary heating to the inner furnace from the outside, and the high temperature generated by the first heater must be borne by the outer furnace. To reduce heat loss, the outer furnace is made of a non-metallic material that is resistant to high temperatures and has poor thermal conductivity. The inner furnace, as the main heating device, supplies heat to the inner furnace from the inside, ensuring uniform temperature within the furnace and utilizing all heat dissipation energy for heating the inner furnace, significantly improving energy utilization efficiency and reducing energy consumption. The inner furnace must possess characteristics of high temperature resistance, good thermal conductivity, and resistance to exhaust gas corrosion, and is made of high-temperature and corrosion-resistant metal materials or composite materials. The coordinated use of these structures ensures that the temperature of the inner furnace meets the requirements, enabling the complete decomposition of difficult-to-decompose components in the waste liquid.

[0019] By incorporating a mixing section, combustion section, burnout section, and insulation layer within the electric heating mechanism, the working space formed by the mixing section, combustion section, and burnout section has a "small at both ends and large in the middle" structure, extending the waste liquid reaction process and time to ensure complete decomposition of harmful components. The insulation layer adopts a multi-layer composite insulation structure, with the innermost layer being refractory fiber material, the middle layer being nano-insulation board, the outermost layer being foamed polyurethane insulation material, and the outermost layer being sealed with a stainless steel plate to minimize heat dissipation from the furnace body.

[0020] By incorporating blades within the mixing mechanism, the rotation of these blades promotes rapid airflow within the combustion zone, achieving uniform heat distribution and effectively preventing incomplete treatment due to uneven heating of the waste liquid. The blades feature an upward-convex arc structure, which not only significantly enhances the impact on the airflow velocity within the combustion zone but also effectively prevents waste liquid from accumulating on the blades due to gravity, thus avoiding obstruction of the waste liquid's flow to the bottom of the waste liquid treatment equipment and ensuring stable and efficient operation of the laboratory waste liquid treatment process.

[0021] By incorporating a first frame, a second frame, and a fourth frame within the scraping mechanism, the connecting frame and the fourth frame deform during installation and connection with the first frame and the connecting frame. Therefore, under the restoring elasticity of the fourth frame and the connecting frame, the first frame tightly adheres to the inner wall of the ash discharge port, utilizing the scraping force generated by the rotation of the first frame to remove scale from the inner wall of the ash discharge port. Furthermore, by utilizing the device's own power source to drive the components, no additional power supply is required, significantly reducing energy consumption and wastewater treatment costs. Through the coordinated operation of each component, the automatic cleaning of the inner wall of the ash discharge port effectively avoids problems such as narrow channels and obstructed ash discharge caused by dust adhesion, ensuring the efficient and stable operation of the wastewater treatment process.

[0022] In summary, this device uses electric heating as its core energy source and achieves waste liquid treatment and equipment maintenance through the collaborative work of multiple components. Attached Figure Description

[0048] Example 1: As Figures 1 to 4 As shown, an embodiment of the present invention provides a multi-thermal core temperature-controlled coupled laboratory waste liquid disposal equipment, including a waste liquid treatment equipment body 1, a base 2 installed at the bottom of the waste liquid treatment equipment body 1, an insulation door 3 installed on the waste liquid treatment equipment body 1, a waste liquid inlet 4 at the top of the waste liquid treatment equipment body 1, a denitrification agent nozzle 5 on the side of the waste liquid treatment equipment body 1 near the waste liquid inlet 4, a tail gas outlet 6 at the bottom of the waste liquid treatment equipment body 1, and an ash collection port 7 at the bottom of the waste liquid treatment equipment body 1; an electric heating mechanism, which is used to treat the laboratory waste liquid by using electrical energy to generate heat, and is connected to the waste liquid treatment equipment body 1; and a mixing mechanism, which is used to mix the heat generated by the electric heating mechanism evenly in the working space, and is connected to the electric heating mechanism.

[0049] In the above scheme, by setting up an electric heating mechanism, the water or low-boiling-point organic matter in the waste liquid can be evaporated. At the same time, the high temperature decomposes harmful substances in the organic waste liquid, such as hydrocarbons, pesticides, and phenols, into inorganic substances such as CO2 and H2O. This provides sufficient heat to the waste liquid, allowing it to evaporate completely. Compared with treatment methods that use fossil fuels, gaseous or liquid fuels as combustion energy, electric heating technology does not require fuel storage and has the characteristics of being ready to use immediately and having high temperature control accuracy. It is safer and more practical.

[0050] Specifically, the electric heating mechanism is used to treat laboratory waste liquid using electrical energy. The electric heating mechanism is connected to the main body 1 of the waste liquid treatment equipment. Compressed air is connected and a nozzle is installed at the waste liquid inlet 4, allowing the waste liquid to be atomized and sprayed into the main body 1 of the waste liquid treatment equipment. Simultaneously, atomized denitrification agent is introduced at the denitrification agent nozzle 5, promoting full contact and reaction between the waste liquid and the denitrification agent. The reaction between the polymer composite denitrification agent and the atomized waste liquid can effectively inhibit the generation of nitrogen oxides at high temperatures, reducing the difficulty of subsequent tail gas denitrification treatment. The base 2 and nozzle both utilize existing mature technologies; their working principles and specific structures will not be elaborated here. The electric heating mechanism provides sufficient heat to the waste liquid, ensuring complete evaporation: firstly, heating evaporates water or low-boiling-point organic matter in the waste liquid; simultaneously, high temperature decomposes harmful substances in the organic waste liquid, such as hydrocarbons, pesticides, and phenols, into inorganic substances such as CO2 and H2O. Compared to processing methods that use fossil fuels, gaseous or liquid fuels as combustion energy, electric heating technology does not require fuel storage, has the characteristics of being ready to use immediately, and has high temperature control accuracy, making it safer and more practical.

[0051] like Figures 1 to 4 As shown, the electrothermal mechanism includes an outer furnace 11 installed inside the main body 1 of the waste liquid treatment equipment. An inner furnace 12 is installed inside the main body 1. A mixing section 8 is located at the top of the main body 1, a combustion section 9 is located at the bottom of the mixing section 8, and a burnout section 10 is located at the bottom of the combustion section 9. An insulation layer 13 is installed on the outer wall of the main body 1. A first heater is installed inside the outer furnace 11, and a second heater is installed inside the inner furnace 12. A middle furnace is formed between the outer furnace 11 and the inner furnace 12. A thermocouple 14 is installed on one side of the main body 1. The first heater, the second heater, and the thermocouple 14 all utilize existing mature technologies, and their working principles and specific structures will not be elaborated here. The outer furnace 11 provides auxiliary heating to the middle furnace from the outside. The high temperature generated by the first heater must be borne by the outer furnace 11. To reduce heat loss, the outer furnace 11 is made of a non-metallic material with high temperature resistance and poor thermal conductivity. Its internal heater can be designed as a straight line with a constant cross-section, a straight line with a variable cross-section, or a narrow U-shape. The inner furnace 12 serves as the main heating device, supplying heat to the central furnace from the inside. This ensures uniform temperature within the furnace and utilizes all heat dissipation energy for heating the central furnace, significantly improving energy utilization efficiency and reducing energy consumption. The high temperature generated by the second heater needs to be rapidly conducted to the central furnace; therefore, the inner furnace 12 must possess characteristics of high temperature resistance, good thermal conductivity, and resistance to exhaust gas corrosion. It is constructed from high-temperature and corrosion-resistant metal materials or composite materials. Depending on site requirements, the inner furnace 12 can be segmented to ensure that the temperature of the central furnace meets the requirements, enabling the complete decomposition of difficult-to-decompose components in the waste liquid.

[0052] The working space, consisting of mixing section 8, combustion section 9, and burnout section 10, has a "small at both ends and large in the middle" structure, extending the waste liquid reaction process and time to ensure complete decomposition of harmful components. Each section is made of temperature- and corrosion-resistant stainless steel, offering advantages such as simple processing, long service life, and high strength. The insulation layer 13 employs a multi-layer composite insulation structure: the innermost layer is refractory fiber material, the middle layer is nano-insulation board, the outermost layer is foamed polyurethane insulation material, and the outermost layer is sealed with a stainless steel plate, minimizing furnace heat dissipation. The nozzles are dual-fluid nozzles; the waste liquid is pumped, and compressed air is sent to the nozzles via a compressor for mixing and atomization. The atomization power mainly comes from compressed air, making it more energy-efficient than atomization methods that simply increase liquid pressure.

[0053] In summary, this device forms a heating system where the inner furnace 12 is located at the central axis of the main body 1 of the waste liquid treatment equipment, and the outer furnace 11 is arranged on both sides of the inner furnace 12, thus providing main heating from the inner furnace 12 and auxiliary heating from the outer furnace 11. After entering the mixing section 8 through the waste liquid inlet 4, the waste liquid reacts with the denitrification agent introduced through the denitrification agent nozzle 5, inhibiting the generation of nitrogen oxides at high temperatures. It then enters the combustion section 9, where the temperature is monitored in real time and precisely controlled by thermocouples 14 to ensure complete evaporation of the waste liquid. Finally, it enters the burnout section 10, where exhaust gas is discharged from the exhaust gas outlet 6 and waste residue is discharged from the ash outlet 7. This structure uses electricity as an energy source to treat laboratory waste liquid, and the coordinated operation of all components effectively improves treatment efficiency.

[0054] Specifically, temperature threshold setting:

[0055] T1, 1100℃: Nozzle start-up temperature, minimum maintenance temperature during waste liquid treatment.

[0056] T2, 1120℃: The shut-off temperature of the first heater.

[0057] T3, 1150℃: The shut-off temperature of the second heater.

[0058] T4, 1000℃: System fault trigger temperature. If the temperature detected during dual heater operation is lower than this value, a fault is determined.

[0059] Workflow:

[0060] After the device is started, the first and second heaters begin to heat the central furnace. When thermocouple 14 detects that the temperature has reached T1 and stabilized for 5 minutes, the nozzles are activated, atomizing the waste liquid and spraying it into the mixing section 8 area. The waste liquid reacts with the atomized denitrification agent introduced at the denitrification agent nozzle 5 to inhibit the formation of nitrogen oxides. The system dynamically adjusts the heating strategy according to the different calorific values ​​of the waste liquid.

[0061] Low calorific value waste liquid: If the temperature does not exceed T2 15 minutes after the nozzle is started, the dual heaters will continue to run for 5 minutes;

[0062] Medium-calorific-value waste liquid: When the temperature reaches or exceeds T2 and is maintained for 15 minutes, turn off the first heater;

[0063] High-calorific-value waste liquid: If the temperature rises to T3 and stabilizes for 5 minutes after the first heater is turned off, the second heater is turned off.

[0064] If the temperature drops below T1 during processing, both heaters will restart; if the temperature drops below T4 while both heaters are running simultaneously, the system will determine that the heaters are faulty and shut down.

[0065] Example 2: Figures 4 to 8 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0066] The mixing mechanism is used to mix the heat generated by the electric heating mechanism evenly in the working space. The mixing mechanism is connected to the electric heating mechanism. The mixing mechanism includes a mounting frame 17 installed on the inner furnace chamber 12. There are two mounting frames 17 installed on the top and bottom of the inner furnace chamber 12 respectively. The side of the mounting frame 17 away from the inner furnace chamber 12 is fixedly connected to the inner wall of the combustion section 9. The side of the mounting frame 17 close to the inner furnace chamber 12 is rotatably connected to the inner furnace chamber 12. Specifically, the inner wall of the mounting frame 17 is provided with a rotating groove. A rotating block adapted to the shape of the rotating groove is installed on the inner furnace chamber 12. Blades 16 are installed at equal intervals on the outer wall of the inner furnace chamber 12. A connecting frame 18 is fixedly connected to the bottom of the inner furnace chamber 12. There are two connecting frames 18 symmetrically installed at the bottom of the inner furnace chamber 12. A toothed ring 19 is fixedly connected to the bottom of the connecting frame 18. A drive assembly 15 is installed on one side of the combustion section 9. The drive assembly 15 consists of a drive motor and two bevel gears. In operation, one of the bevel gears meshes with the gear ring 19, which rotates under the drive of the drive motor. Since both the drive motor and the bevel gear utilize existing mature technologies, their working principles and specific structures will not be elaborated here. To ensure the normal operation of the drive motor, an exhaust vent is provided on the main body 1 of the waste liquid treatment equipment for heat dissipation.

[0067] Considering that the outer furnace chamber 11 is symmetrically arranged on both sides of the inner furnace chamber 12, rather than being a ring-shaped enclosure, uneven temperature may easily occur in the combustion section 9 when the inner furnace chamber 12 provides auxiliary heating. To address this, the device uses a drive assembly 15 to rotate the gear ring 19, which in turn drives the inner furnace chamber 12 to rotate via the connecting frame 18. The inner furnace chamber 12 then drives the blades 16 on it to rotate. This rotational motion promotes rapid airflow within the combustion section 9, achieving uniform heat distribution and effectively preventing incomplete treatment due to uneven heating of the waste liquid. Furthermore, this design is simple, convenient, and efficient.

[0068] Furthermore, the top of the ash discharge port 7 has an installation groove larger than the toothed ring 19. The toothed ring 19 is stably installed in the installation groove, and its height can be finely adjusted within a certain range. The connecting frame 18 is an arc-shaped structure that protrudes away from the center of the waste liquid treatment equipment body 1. The connecting frame 18 is easy to deform and bend under external force, while achieving efficient agitation of the air in the combustion section 9. The blades 16 are arranged equidistantly in a spiral pattern along the outer wall of the inner furnace 12. This design can fully promote the airflow in the combustion section 9, so that the heat is evenly distributed, thereby ensuring the quality of waste liquid treatment. In addition, the blades 16 adopt an upwardly convex arc-shaped structure. This design can not only significantly improve the influence on the airflow velocity in the combustion section 9, but also effectively prevent waste liquid from accumulating on the blades 16 due to gravity, avoiding obstruction of the flow of waste liquid to the bottom of the waste liquid treatment equipment body 1, and ensuring the stable and efficient operation of laboratory waste liquid treatment.

[0069] like Figures 7 to 16As shown, a scraping mechanism is installed inside the ash discharge port 7. The scraping mechanism includes a first frame 20 installed at the bottom of the toothed ring 19. A third frame 23 is fixedly connected to the top and bottom of the first frame 20. A second frame 21 is fixedly connected to the top of the first frame 20. The second frame 21 is hook-shaped. A slot 22 is opened at the bottom of the connecting frame 18. A fourth frame 24 is fixedly connected to the bottom of the first frame 20. A limit rod 27 is installed at the bottom of the ash discharge port 7. A first slot 25 that matches the shape of the limit rod 27 is opened on the fourth frame 24. A second slot 29 and a third slot 31 are opened at the bottom of the ash discharge port 7. A first limiting groove 28 and a second limiting groove 30 are opened at the bottom of the ash discharge port 7. The bottom of the ash discharge port 7 is rotatably connected to the rotating block 32. The first limiting groove 28, the second slot 29, the second limiting groove 30, and the third slot 31 are all set on the rotating block 32. During normal operation, the fourth frame 24 is placed into the second slot 29, and the limiting rod 27 is sequentially inserted into the first limiting groove 28 and the first slot 25 to securely fix the fourth frame 24. At this time, the second frame 21 at the top of the first frame 20 remains separate from the connecting frame 18. When it is necessary to clean the inner wall of the ash discharge port 7, the fourth frame 24 is installed into the third slot 31, and the fourth frame 24 immediately bends and deforms. Then, the limiting rod 27 is inserted into the second limiting groove 30 and extends into the first slot 25, so that the fourth frame 24 is firmly fixed in the third slot 31. At this time, the first frame 20 is driven by the structure to move closer to the toothed ring 19 and press the toothed ring 19. The toothed ring 19 then presses the connecting frame 18 upward, causing the connecting frame 18 to undergo slight bending deformation. Then, the first frame 20 is rotated, and the second frame 21 is manipulated to hook the bottom of the connecting frame 18 and insert into the slot 22, completing the connection between the first frame 20 and the connecting frame 18. Under the restoring elastic force of the fourth frame 24 and the connecting frame 18, the first frame 20 fits tightly against the inner wall of the ash discharge port 7. At this time, starting the drive assembly 15 can drive the first frame 20 to rotate, and use the scraping force generated by the rotation to remove the scale on the inner wall of the ash discharge port 7.

[0070] The cleaning structure cleverly utilizes the device's own power source to drive the component 15, eliminating the need for additional power supply and significantly reducing energy consumption and waste liquid treatment costs. Through the coordinated operation of various components, it achieves periodic automatic cleaning of the inner wall of the ash discharge port 7, effectively avoiding problems such as narrow channels and obstructed ash discharge caused by dust adhesion, and ensuring the efficient and stable operation of the waste liquid treatment process.

[0071] Furthermore, the first frame 20, the second frame 21, the third frame 23, and the fourth frame 24 are an integral structure. The integral structure has better stability and is easier to produce and use. The fourth frame 24 is made of plastic material, which has good deformation ability and is relatively light. The side of the fourth frame 24 away from the ash discharge port 7 is provided with a weakening part 26, so that the part of the fourth frame 24 near the weakening part 26 is more likely to deform under the action of external force. The cross-section of the fourth frame 24 is square, so that the fourth frame 24 will not rotate when installed in the second slot 29 and the third slot 31. The cross-section of the limiting rod 27 is L-shaped, which facilitates the operation of the limiting rod 27.

[0072] The working principle of the technical solution provided by this invention is as follows:

[0073] When in use, its working principle is as follows:

[0074] After the device starts up, the first and second heaters begin to heat the central furnace. Once thermocouple 14 detects that the temperature has reached T1 and stabilized for 5 minutes, the nozzles activate, atomizing the waste liquid and spraying it into the mixing section 8. The waste liquid reacts with the atomized denitrification agent introduced at the denitrification agent nozzle 5, inhibiting the formation of nitrogen oxides. The system dynamically adjusts the heating strategy according to the different calorific values ​​of the waste liquid.

[0075] Low calorific value waste liquid: If the temperature does not exceed T2 15 minutes after the nozzle is started, the dual heaters will continue to run for 5 minutes;

[0076] Medium-calorific-value waste liquid: When the temperature reaches or exceeds T2 and is maintained for 15 minutes, turn off the first heater;

[0077] High-calorific-value waste liquid: If the temperature rises to T3 and stabilizes for 5 minutes after the first heater is turned off, the second heater is turned off.

[0078] If the temperature drops below T1 during processing, both heaters will restart; if the temperature drops below T4 while both heaters are running simultaneously, the system will determine that the heaters are faulty and shut down.

[0079] The device drives the motor and bevel gear of the drive component 15 through the transmission component to rotate the gear ring 19, which in turn drives the connecting frame 18, the inner furnace chamber 12 and the spirally arranged blades 16 to rotate in sequence. The arc structure of the blades 16 accelerates the air flow, so that the heat is fully mixed and the waste liquid is evenly heated and completely decomposed.

[0080] During normal operation, the fourth frame 24 is fixed to the second slot 29, and the first frame 20 is separated from the connecting frame 18. When cleaning the inner wall of the ash discharge port 7, the fourth frame 24 is installed into the third slot 31 and bent. After being fixed by the limiting rod 27, the second limiting groove 30, and the first slot 25, the first frame 20 presses against the toothed ring 19 to deform the connecting frame 18, and the second frame 21 hooks onto the bottom of the connecting frame 18 to complete the connection. Under the rebound force of the fourth frame 24 and the connecting frame 18, the first frame 20 is pressed tightly against the inner wall of the ash discharge port 7. Activating the drive assembly 15 will drive the first frame 20 to rotate and scrape off the scale on the inner wall. This cleaning process reuses the device's own power source, requiring no additional energy consumption, effectively avoiding blockage of the ash discharge port 7 channel, and reducing operating costs.

[0081] The entire system achieves efficient treatment of laboratory waste liquid through the coordinated operation of precise temperature control, dynamic heating, forced convection, and automatic cleaning, while also being both safe and economical.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
