Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste treatment devices, and particularly relates to a resourceful treatment device for organic waste. BACKGROUND

[0002] Under the background of rapid development of today's society, with the accelerated advancement of urbanization, the amount of organic waste is showing a significant growth trend. As an important part of organic waste, the treatment of municipal waste is becoming increasingly prominent, and has become a major challenge faced by countries in the field of environmental protection. Municipal waste is not only large in quantity but also complex in composition, covering household garbage, commercial waste and part of city green pruning, etc. Effective management and proper treatment of municipal waste is of great significance to maintaining urban environmental health, protecting residents' health and promoting sustainable development.

[0003] At present, the treatment technology for organic waste has diversified development, mainly including landfill method, composting method, incineration method and pyrolysis gasification method. Although the landfill method is simple in operation and low in cost, it occupies a large amount of land resources and may cause soil and groundwater pollution. The composting method is suitable for waste with high biomass content, which is converted into organic fertilizer through microbial decomposition, but the treatment period is long, the land occupation is large and the material requirements are high. The incineration method can quickly reduce the volume and produce heat, but harmful gases may be released during the treatment process, affecting air quality. The pyrolysis gasification method is a relatively new treatment technology, which converts organic matter into gaseous fuel through high-temperature pyrolysis, but the equipment investment is large, and the technology maturity and operation stability need to be improved.

[0004] However, these existing technologies generally have the problem of low energy utilization efficiency in the process of treating organic waste. In particular, the waste heat generated in the incineration and pyrolysis gasification processes is often directly discharged into the atmosphere without effective recovery and utilization, which not only causes great waste of energy, but also aggravates the thermal pollution of the environment. CONTENT OF THE INVENTION

[0005] The purpose of the embodiment of the present application is to provide a resourceful treatment device for organic waste, which can fully utilize the gas waste heat generated in the treatment process, avoid waste of resources, and ensure that the discharged gas will not pollute the environment.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0025] In the present application, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them.

[0026] As shown in Figure 1 The present embodiment provides a resource processing device for organic waste, which comprises: an extrusion dewatering machine 1, a drying machine 2, a first reaction kettle 3, a second reaction kettle 4, a third reaction kettle 5, a cooling machine 6 and a recovery tank 7 which are sequentially communicated through pipelines. The top of the first reaction kettle 3 is sequentially communicated with a first dust removal machine 8 and an oxidation denitration machine 9 through a gas pipeline. The oxidation denitration machine 9 is communicated to the drying machine 2 through a gas pipeline. The second reaction kettle 4 is communicated to a second dust removal machine 10 through a gas pipeline. The second dust removal machine 10 is communicated to the first reaction kettle 3 through a gas pipeline. The cooling machine 6 is connected to cooling gas. The cooling gas is transported to the second reaction kettle 4 through a gas pipeline after heat exchange in the cooling machine 6. The heating temperature of the first reaction kettle 3 is T1, the heating temperature of the second reaction kettle 4 is T2, and the heating temperature of the third reaction kettle 5 is T3, and T1 < T2 < T3.

[0027] Based on the above scheme, first, the organic waste enters the extrusion dewatering machine 1, and through the mechanical pressure, the excess water in the waste is squeezed out, reducing the energy consumption and water disturbance in the subsequent treatment process. The dewatered organic waste is then sent to the drying machine 2, which uses external heat source to further dry the waste, so that the waste reaches the conditions suitable for subsequent pyrolysis treatment.

[0028] Next, the dried organic waste enters the first reaction kettle 3. The kettle is set to a lower heating temperature T1, at which the remaining water in the waste is gradually emitted in the form of water vapor. At the same time, the waste begins to preheat, preparing for the subsequent pyrolysis reaction. The gas produced (mainly water vapor) enters the first dust collector 8 through the gas pipeline, and the filter device in the dust collector effectively removes the particulate matter in the gas, ensuring the cleanliness of the gas. Subsequently, the gas enters the oxidation denitration machine 9, which uses oxidation reaction to remove nitrogen oxides in the gas, further purifying the gas. The purified gas is sent back to the drying machine 2 as a heat source for recycling, improving the energy utilization efficiency.

[0029] The organic waste after preheating enters the second reaction kettle 4. The heating temperature T2 of the kettle is higher than that of the first reaction kettle 3, providing a more suitable pyrolysis environment for the waste. At this temperature, the waste undergoes thermal cracking and reverse reduction reactions, producing gas-phase organic substances. These gases enter the second dust collector 10 through the gas pipeline, and the filter device in the dust collector removes the particulate matter in the gas again. Part of the purified gas can be returned to the first reaction kettle 3 as a supplemental heat source; the rest can be further processed or discharged according to specific design.

[0030] Finally, the organic waste treated by the second reaction kettle 4 enters the third reaction kettle 5. The heating temperature T3 of the kettle is the highest among the three reaction kettles, providing a deep pyrolysis environment for the waste. At this temperature, the waste undergoes more thorough pyrolysis reactions, ultimately producing organic carbon. These organic carbon can be used to produce biochar, soil conditioner and other high-value products.

[0031] The products after pyrolysis enter the cooling machine 6. In the cooling machine 6, the cooling gas (such as air or inert gas) is introduced and exchanges heat with the pyrolysis products, cooling the products to a suitable temperature for collection. The cooled products are collected in the recovery tank 7 for subsequent resource utilization. The high-temperature gas after heat exchange is transported to the second reaction kettle 4 as a supplemental heat source, achieving efficient recovery of waste heat.

[0032] Throughout the entire treatment process, by setting dust removal and oxidation denitration device, effectively remove the treatment process of particulate matter and nitrogen oxides and other pollutants, to ensure the cleanliness of the exhaust gas and environmental friendliness. At the same time, through the setting of waste heat recovery system, the gas waste heat generated in the treatment process is fully utilized in preheating and supplementary heat source, etc., significantly improving the energy utilization efficiency.

[0033] In summary, the organic waste resource treatment device proposed in the present application not only realizes efficient treatment and resource utilization of organic waste, but also takes into account the dual goals of environmental protection and energy saving. The device has the advantages of high treatment efficiency, high resource recovery rate, low energy consumption, and small environmental pollution, providing a new and efficient solution for sustainable treatment of organic waste.

[0034] Further, it also includes a filter 11, and the bottom of the extrusion dewatering machine 1 is provided with a drainage port connected to the filter 11 through a pipeline. The organic waste is sent into the extrusion dewatering machine 1, which applies pressure to the waste through the internal mechanical structure, thereby extruding the excess moisture therein, which contains a high content of impurities such as suspended solids, organic matter, etc. The drainage port at the bottom of the extrusion dewatering machine 1 is responsible for discharging these impurity-containing moisture, which is directly guided to the filter 11 through a special pipeline. The filter 11 is equipped with precise filtering devices such as filter screens, filter cloths or activated carbon, etc. inside, which can effectively trap and remove impurities in the moisture. After the treatment of the filter 11, the originally impurity-laden wastewater becomes clear and transparent, reaching the standard for reuse. This part of purified water resources can be diversified for reuse according to actual needs, such as for flushing equipment, farmland irrigation, industrial cooling, etc.

[0035] Further, the filter 11 is internally provided with a first filter screen and a second filter screen in sequence, and the density of the first filter screen is greater than that of the second filter screen. The filter 11 is internally provided with a first filter screen and a second filter screen in sequence, and the density of the first filter screen is greater than that of the second filter screen. When the water containing impurities enters the filter 11, it will first pass through the first filter screen. Since the density of the first filter screen is relatively large, it can effectively intercept and remove larger particulate impurities in the water, such as suspended solids, macromolecular organic matter, etc. After being treated by the first filter screen, the impurity content in the water is significantly reduced, but it may still contain some small particles or soluble organic matter. Then, the water treated by the first filter screen will enter the second filter screen. Since the density of the second filter screen is smaller, it can further remove small particles and soluble organic matter in the water, so that the water quality is further improved. After being treated by the second filter screen, the water becomes clear and transparent, reaching the standard for reuse, and the water resource treated by the double filtration can be diversified according to actual needs.

[0036] Specifically, 90℃≦T1≦120℃, 150℃≦T2≦420℃, 450℃≦T3≦650℃. In the first reaction kettle 3, a relatively low temperature range (90℃ to 120℃) is set. This temperature range helps the remaining water in the waste to gradually evaporate in the form of water vapor, while the waste begins to preheat, preparing for the subsequent pyrolysis reaction. At this temperature, the organic matter in the waste will not decompose violently, thereby avoiding the generation of too much harmful gas and tar.

[0037] The temperature of the second reaction kettle 4 is set between 150℃ and 420℃, which is a medium temperature range. At this temperature, the organic matter in the waste begins to decompose by pyrolysis, decomposing into gas, liquid and solid products. As the temperature rises, the rate and degree of pyrolysis reaction will also increase, thereby producing more gas and liquid products. However, too high a temperature can cause excessive sintering of solid products (such as coke), affecting the quality of the products and subsequent utilization.

[0038] The temperature of the third reaction kettle 5 is set between 450℃ and 650℃, which is a relatively high temperature range. At this temperature, the organic matter in the waste is almost completely decomposed, producing a large amount of gas and a small amount of solid residue. High temperature helps to accelerate the progress of pyrolysis reaction, improve the yield and quality of gas products. At the same time, the carbon content in the solid residue will also be reduced, making the residue easier to handle and utilize.

[0039] In some embodiments, the bottom of the first reactor 3 is provided with a first electric heater, the bottom of the second reactor 4 is provided with a second electric heater, and the bottom of the third reactor 5 is provided with a third electric heater. The operating power of the third electric heater is greater than that of the second electric heater, and the operating power of the second electric heater is greater than that of the first electric heater. By configuring electric heaters with different powers, the temperature in each reactor can be more accurately controlled, ensuring that the pyrolysis process can be carried out within the optimal temperature range. The electric heaters with different powers can be adjusted according to the temperature requirements in the reactor, thereby increasing the rate and efficiency of the pyrolysis reaction and increasing the yield of gas and liquid products. Moreover, the electric heaters with different powers can coordinate with each other to ensure the stability and continuity of the entire pyrolysis process, thereby improving the overall performance and reliability of the system.

[0040] In addition, a pressure pump is arranged on the gas pipeline between the first reactor 3 and the second dust removal machine 10, and / or a pressure pump is arranged on the gas pipeline between the cooler 6 and the second reactor 4. The arrangement of the pressure pump enables the gas to maintain stable pressure and flow during transmission, reduces gas loss or leakage caused by pressure fluctuations, and improves the operating efficiency of the entire system. Through stable gas transmission, it can be ensured that the gas generated during the pyrolysis process can be timely and efficiently transferred to the front equipment for recycling, such as the first reactor 3, the second reactor 4, etc., thereby improving the resource recycling rate.

[0041] Optionally, the first reactor 3, the second reactor 4, and the third reactor 5 are each provided with a stirring assembly. Inside each reactor, a stirring assembly is installed, which generally consists of a stirrer, a stirring shaft, and a driving device. The stirrer can be of various types such as paddle, anchor, and ribbon, selected according to the shape and size of the reactor and the characteristics of the processed material. The stirring assembly drives the stirring shaft to rotate through the driving device (such as a motor), which in turn drives the stirrer to stir inside the reactor. The purpose of stirring is to promote the mixing and uniform distribution of the material inside the reactor, thereby improving the rate and efficiency of the pyrolysis reaction. The introduction of the stirring assembly enables the material inside the reactor to be more fully mixed and contacted, thereby improving the rate and efficiency of the pyrolysis reaction, which helps to shorten the processing time and improve the processing capacity of the entire system. The continuous operation of the stirring assembly helps to maintain the flowability and stability of the material inside the reactor, preventing the material from accumulating or caking during the reaction, which helps to reduce the failure rate and maintenance cost of the system and improve the overall performance and reliability of the system.

[0042] Further, the bottom of the third reactor 5 is provided with a discharge port, which is connected to the cooling machine 6 through a pipeline, and a control valve is arranged at the discharge port. A special discharge port is designed at the bottom of the third reactor 5. The main function of this discharge port is to discharge the organic carbon or other solid products generated after the pyrolysis reaction is completed from the reactor. In order to achieve this function, the discharge port is connected to the cooling machine 6 through a section of high-temperature-resistant and corrosion-resistant pipeline. This pipeline ensures that the pyrolysis products will not condense or block during transmission due to temperature drop, and also prevents the corrosion of harmful substances to the pipeline.

[0043] At the discharge port, a precise control valve is installed. The function of this control valve is to accurately control the timing and flow of discharge according to the needs of the processing process. When the pyrolysis reaction in the third reactor 5 reaches the predetermined condition and the product has stabilized, the control valve will be opened to allow the pyrolysis products to enter the cooling machine 6 through the pipeline. At the same time, by adjusting the opening of the control valve, fine adjustment of the discharge flow can also be realized to ensure that the cooling machine 6 can efficiently process the entering solid products.

[0044] In addition, the design of the control valve also takes into account safety and reliability. It is made of high-temperature-resistant and wear-resistant materials, which can maintain stable performance in extreme working environment. At the same time, the control valve is also equipped with a fault alarm system, which will immediately issue an alarm and automatically close the control valve in case of failure or abnormal situation, to prevent the leakage of pyrolysis products or cause other safety hazards.

[0045] At the same time, the recycling box 7 is provided with a screening assembly, which includes a screen and a vibration motor, and the drive shaft of the vibration motor is connected to the screen. The screen is the core part of the screening assembly, which is usually made of wear-resistant and corrosion-resistant materials such as stainless steel or alloy steel. The size of the screen aperture is determined according to the particle size requirements of the processed products to ensure that different particle sizes of the products can be effectively separated. When the cooled products enter the recycling box 7, they will fall on the screen, and the smaller particle size products will fall into the collection container below through the screen holes.

[0046] The vibration motor is the key component to drive the vibration of the screen. Its drive shaft is connected to the screen, and when the motor starts, the drive shaft will drive the screen to vibrate at high frequency. This vibration not only helps the uniform distribution of the products on the screen, but also improves the screening efficiency, making it easier for smaller particle size products to pass through the screen holes. At the same time, vibration also helps to remove the blockage on the screen to prevent faults during the screening process.

[0047] Through the screening and vibration of the screening assembly, the cooled product is effectively separated into particles of different particle sizes. These particles can be further processed or utilized as needed. For example, larger particle size particles can be used as raw materials for biochar, while smaller particle size particles can be used to produce soil conditioners or other high-value products. The operation of the screening assembly is relatively simple, and the screening process can be started by simply starting the vibration motor. At the same time, in order to maintain the stability of the screening efficiency and prolong the service life of the screen, it is necessary to regularly clean and maintain the screen. This includes removing residues on the screen, checking the wear of the screen, and replacing damaged screens in a timely manner.

[0048] Preferably, the materials of the first reaction kettle 3, the second reaction kettle 4 and the third reaction kettle 5 are all stainless steel. Based on the many advantages of stainless steel, including: it is highly corrosion resistant, can resist the corrosion of corrosive gases and liquids that may be produced during the pyrolysis process; excellent high temperature resistance, can withstand high temperature working conditions without deformation or failure; good mechanical properties, can withstand the pressure and mechanical stress that the reaction kettle may be subjected to during operation; smooth surface, easy to clean and maintain, maintain internal hygiene and cleanliness, prevent cross contamination; at the same time, as a recyclable material, stainless steel meets the requirements of environmental protection and sustainable development. Therefore, as the material of these reaction kettles, stainless steel not only ensures the reliability and durability of the equipment, but also improves the efficiency and safety of the entire treatment process, making it an ideal choice for reaction kettles.
