Description

Technical Field

[0001] The utility model relates to the field of thermochemical treatment of organic solid waste, and more specifically, to an organic solid waste smoldering test device capable of realizing real-time monitoring of multiple parameters. Background Art

[0002] Typical organic solid waste includes municipal solid waste, industrial solid waste and agricultural and forestry solid waste, which are characterized by high moisture content, high heavy metal content and low fixed carbon content. Compared with traditional disposal methods such as landfill and agricultural applications, which are often subject to the complex characteristics of organic solid waste (virions, organic pollutants and heavy metals), thermochemical methods such as drying incineration, pyrolysis gasification, hydrothermal carbonization, etc. have gradually attracted attention due to their advantages such as short reaction time, large volume reduction rate and carbonization of organic matter. However, when faced with a type of organic solid waste with high moisture and heavy metal content in fuel, the current disposal methods still cannot be directly treated in actual engineering applications or require the additional addition of high calorific value fuels. There are still problems such as long process flow, heavy pollution and high energy consumption.

[0003] In recent years, self-sustaining smoldering has gradually attracted attention as a new alternative technology for the thermochemical treatment of organic solid waste. The smoldering process can achieve self-sustaining operation by stimulating the fuel's own energy, and has a natural advantage in the treatment of organic solid waste with high moisture content. Unlike traditional pyrolysis and incineration technologies, self-sustaining smoldering technology does not require a pre-drying process, and no additional high-calorific value fuel needs to be added during the operation phase, which can greatly reduce construction and operation costs. However, to date, the active control methods and large-scale processes of smoldering disposal technology are not yet mature, and a large amount of laboratory research is still needed to explore the influence mechanism of different parameters on the smoldering process.

[0004] Typically, in smoldering treatment, high-water content organic solid waste is mixed with an inert medium (such as quartz sand) to form a porous medium condition that is conducive to the propagation of smoldering. The porous medium condition mainly plays the role of enhancing heat storage and oxygen propagation. The smoldering reaction process can be divided into a drying zone, a pyrolysis zone, a combustion zone, and a burned zone. The use of a forward upward smoldering configuration can maximize the use of the waste heat in the burned zone. However, in organic solid waste smoldering tests, 304 stainless steel is usually used to make the reactor body. This stainless steel easily oxidizes in high humidity and high temperature environments, interfering with the overall reaction. At the same time, various functional units are connected by welding or flanges (such as CN 117072980 B), making it difficult to replace individual components. In addition, the entire smoldering device is large in size and weight. A single working condition test consumes a lot of manpower and material resources, which is not conducive to the experimental exploration of multi-parameter smoldering. In addition, the smoldering process of organic solid waste involves multiple chemical reactions occurring simultaneously, but the current monitoring of smoldering data focuses more on temperature data and exhaust gas data, such as CN112648619 B and CN113531556 B. Although these two parts of data can reflect the status of the entire smoldering process, they are not sufficient for further analysis of the intermediate process of smoldering.

[0035] See also Figures 1 to 5The present embodiment provides an organic solid waste smoldering test device, comprising: a smoldering reactor, a smoldering control base unit and a weighing unit. Specifically, the smoldering reactor comprises a main reactor 2 for filling a mixture of organic solid waste, and an arch cover 1 arranged on the top of the main reactor 2, and the main reactor 2 is made of a transparent material; the smoldering control base unit comprises a socket portion 6 and a base tray 8, the base tray 8 is provided with a socket portion 6, the main reactor 2 is socketed on the socket portion 6, and an air distributor 16 and a heater 5 are provided in the socket portion 6. The air distributor 16 is used for air supply control of the organic solid waste smoldering reaction, and the heater 5 is used for heating control of the organic solid waste smoldering reaction; the weighing unit comprises a weighing platform 11 and a weighing sensor 12, the weighing platform 11 is placed on the weighing sensor 12, the smoldering control base unit is arranged on the weighing platform 11, the weighing unit control signal is connected to a data converter 14, and the data converter 14 is provided with a filter and a display.

[0036] The smoldering reactor mainly includes a main reactor 2, which is the area where the smoldering reaction occurs and is used to fill the mixture of organic solid waste. Figure 1 As shown, the main reactor 2 is divided into three sections from bottom to top, namely the rectifying section 17, the fuel section 18 and the insulation section 19. In specific implementation, the rectifying section 17 is mostly filled with gravel of different particle sizes, which mainly plays the role of rectifying the incoming air flow, making the air flow more uniform in the horizontal direction. The fuel section 18 is the main part of the main reactor 2. Since the existing organic solid waste is mostly wet material with a high moisture content, the high-humidity organic solid waste is usually mixed with fine sand to form a relatively uniform porous medium, and then directly filled into the main reactor 2. The top layer in the main reactor 2 is the insulation section 19, which is directly filled with fine sand to ensure that the smoldering test is carried out completely.

[0037] Among them, the data converter can convert the pressure signal of the weighing sensor into a digital signal and perform real-time filtering on the noise in the signal. The data converter panel is equipped with a data display screen and signal control buttons, and the converted signal can be directly output as an editable file.

[0038] This embodiment can observe the smoldering process of organic solid waste in the main reactor made of transparent material and obtain data of the smoldering process of organic solid waste in real time through a weighing unit. In addition, the test device of this embodiment has the characteristics of simple structure and flexible and easy operation.

[0039] In certain embodiments, the main reactor 2 is made of quartz material, and both the upper and lower ends of the main reactor 2 are open. The upper end of the main reactor 2 is a frosted opening and is connected to the arch cover 1, and the lower end of the main reactor 2 is a smooth opening that is socketed with the smoldering control base unit. A digital camera is provided on the outside of the main reactor 2. In a specific implementation, the outer layer of the main reactor 2 is not wrapped with aluminum silicate ceramic insulation cotton. Since the main reactor 2 is made of transparent quartz, the quartz material can withstand high temperatures of 1500°C; the main reactor 2 is cylindrical with an aspect ratio of 5. When conducting a smoldering test, it can be approximately considered as a one-dimensional propagation process, which simplifies the smoldering analysis. Then, a digital camera (DV) can be used to record the smoldering front propagation process under typical working conditions in real time, thereby obtaining smoldering propagation image data during the smoldering process of organic solid waste.

[0040] Among them, under normal test conditions, the outer layer of the main reactor is wrapped with 10 cm thick aluminum silicate ceramic insulation cotton to reduce horizontal heat loss; under special test conditions, the insulation material can be omitted, and a digital camera can use the quartz tube to capture the smoldering propagation process of the reactor edge material, which is conducive to further analysis of the smoldering characteristics.

[0041] Among them, the upper end of the main reactor 2 is a frosted opening that transitions with the arch cover 1. The frosted opening on the upper end of the main reactor 2 can ensure the sealing of the device. The lower end of the main reactor 2 is a smooth opening and is socketed with the smoldering control base unit. This socketing method has the advantage of convenient replacement of the reactor.

[0042] In certain embodiments, a thermocouple bundle 4 is provided in the main reactor. The upper end of the thermocouple bundle 4 is fixed to the top of the arch cover 1, and the lower end of the thermocouple bundle 4 extends downward. The thermocouple bundle 4 is a K-type armored thermocouple arranged at equal intervals. In a specific implementation, a small hole is opened at the top of the arch cover 2 for arranging the thermocouple bundle 4. The thermocouple bundle 4 uses a K-type armored thermocouple arranged at equal intervals. Multiple thermocouples (at least 10) are bound into a line, which has a certain mechanical strength and can be directly inserted into the above-mentioned mixed fuel to monitor the smoldering temperature at the center of the reactor, thereby obtaining smoldering temperature data during the smoldering process of organic solid waste.

[0043] In some embodiments, the dome hood is provided with an air outlet, which is connected to an air bag or flue gas analyzer via a pipe. Specifically, an air outlet 20 is provided at half the radius of the dome hood 1. This outlet 20 can be connected to an air bag or flue gas analyzer for monitoring exhaust gas during the smoldering process, thereby obtaining smoldering exhaust gas data during the smoldering process of organic solid waste.

[0044] In some embodiments, the air distributor 16 has a hollow chamber, and a plurality of air distribution pipes are circumferentially connected to the hollow chamber. An air flow outlet is provided at the bottom of the air distribution pipe. The lower end of the hollow chamber is connected to an L-shaped pipe, and an air flow inlet is provided at the end of the L-shaped pipe. Air is provided at the air flow inlet by an air compressor or a dry air cylinder, and a mass flow meter is provided at the air flow inlet.

[0045] In some embodiments, the top of the heater 5 is a spiral armored structure, and a heating wire and a temperature-sensitive element are provided inside the spiral armored structure. The heating wire and the temperature-sensitive element are controlled by a PLC.

[0046] In practice, the sleeve 6 is open at its top and has two circular holes at its bottom, one for the air distributor 16 and the other for the heater 5. These two components are flexibly connected to the sleeve using high-temperature-resistant adhesive, minimizing the risk of air leaks during operation. During operation, air is supplied by an air compressor or dry air cylinder, with a mass air flow meter controlling the air flow rate to the air distributor 16. The air flow rate into the main reactor 2 ranges from 0 to 10 cm / s. The top of the heater 5 is a spiral armored structure, housing a heating wire and a temperature-sensitive element, both controlled by a PLC. During smoldering, the heater 5 temperature is set to 600°C.

[0047] In some embodiments, the outer periphery of the sleeve portion is provided with a plurality of grooves, in which high-temperature resistant sealing gaskets are placed. Specifically, three circular grooves are opened at the edge of the sleeve portion, in which high-temperature resistant sealing gaskets are placed to ensure the sealing of the sleeve position.

[0048] Among them, the main reactor 2 and the socket part 6 are connected by a sealing gasket 7, which can be quickly installed and removed, so that the main reactor 2 can be quickly replaced in each round of testing, so as to avoid the need to wait for the high temperature in the main reactor 2 to drop to room temperature after each test, thereby greatly improving the efficiency of multi-condition testing.

[0049] In some embodiments, the smoldering control base unit also includes a thermal protection structure layer, and the thermal protection structure layer is connected to the base tray by a number of bolts, and the height of the base tray is adjusted by rotating the number of bolts. In a specific implementation, the smoldering control base unit mainly includes a socket portion 6, a base tray 8 and bolts 9. Four M8 threaded holes are opened on the base tray 8 and are respectively connected with bolts, and the height of the base tray 8 is adjusted by rotating the number of bolts 9. The weighing unit mainly includes a weighing platform 11 and a weighing sensor 12, which are used to collect mass loss data during the smoldering process of organic solid waste in real time. A thermal protection structure layer 10 is placed on the upper end of the weighing platform 11 to protect the weighing unit weighing sensor 12. As shown Figure 3As shown, the load cell 12 is provided with leveling screws 13 at its lower portion. Before each test, the load cell is checked for leveling. The load cell 12 is connected to a data converter 14, which converts the pressure signal from the load cell 12 into a digital signal and performs real-time filtering on any noise present in the signal.

[0050] As an example, after the main reactor 2 is fully filled with material and the thermocouple bundle 4, heater 5, load cell 12, and air distributor 16 are fully commissioned, the smoldering process of organic solid waste can be divided into three stages: preheating, self-sustaining smoldering, and burnout. During the preheating stage, heater 5 is turned on, and the heating wire rapidly heats from room temperature to a preset temperature. This process can be observed by the built-in temperature sensor. The smoldering process of organic solid waste propagates from the bottom up, with the internal fuel burning layer by layer. Here, heater 5 is primarily used to heat the fuel at the bottom of the reactor. The temperature rise of the fuel at different heights can be observed by the thermocouple bundle 4. When the temperature of the bottommost thermocouple (at a height of 1 cm) reaches the ignition temperature (typically 250-350°C), the preheating stage is complete, and the self-sustaining smoldering stage then begins. During the self-sustaining smoldering stage, heater 5 is immediately turned off and air is introduced. Due to the introduction of the oxidant, an oxidation reaction rapidly occurs inside the reactor, consuming a large amount of organic components. The fuel temperature monitored by thermocouple bundle 4 rises rapidly, and a large amount of smoldering gas is released. The fuel mass monitored by weighing sensor 12 decreases rapidly. When the fuel temperature at the top of fuel section 18 begins to drop, it indicates that the burnout stage has begun. It can usually be considered that the smoldering test has ended at this point. The smoldering data obtained are as follows: Figure 5 If the next set of tests is to be carried out, it is necessary to wait for the temperature in the smoldering reactor to drop to room temperature, which consumes a considerable amount of time within the porous medium space. Optionally, the main reactor 2 is wrapped with insulation 3, and the outer surface temperature of the insulation 3 does not exceed 50°C. Therefore, the main reactor 2, which is still hot inside, can be removed and replaced with a spare reactor, and the next set of tests can be started directly.

[0051] In summary, the device of this embodiment can realize real-time monitoring of multiple parameters such as smoldering propagation image data, smoldering temperature data, smoldering exhaust gas data, and smoldering mass loss data during the smoldering process of organic solid waste. The overall structure is simple and easy, the cost is low, and the operation is flexible and easy.
