[0003] Traditional rapid coking experimental equipment has shortcomings in impurity collection. During the coking process, coking coal produces a large amount of coking gas containing impurities such as tar, naphthalene, hydrogen sulfide, ammonia, benzene compounds, and dust. Traditional tar collection devices lack specific design features and cannot efficiently collect these impurities, resulting in harmful substances being emitted into the environment with the gas, potentially causing pollution. Utility Model Content

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

[0032] like Figures 1-3As shown, an embodiment of the present invention provides an apparatus for a rapid coking experiment of coking coal, including a control base 1 for electrical connection with an external power supply, a furnace body 2 with an exhaust port 21 disposed on the control base 1, and a collection component 3 for collecting impurities connected to the exhaust port 21 of the furnace body 2.

[0033] The interior of the furnace body 2 is hollowed out to form a furnace chamber 23. The furnace chamber 23 is equipped with a rotatable tamping device 22 for tamping coking coal. One side of the furnace body 2 is equipped with an openable door 24. Inside the furnace body 2, there are heating components 4 and temperature control components 5 that are electrically connected to the control base 1 respectively. The collection component 3 is electrically connected to the control base 1. The side of the control base 1 is equipped with an operation panel 11 and a display panel 12.

[0034] The apparatus for the rapid coking experiment of coking coal mainly consists of three parts: a control base 1, a furnace body 2, and a collection component 3. The control base 1 acts as the central control unit, electrically connected to external power supply equipment to provide power to the entire apparatus. An operation panel 11 and a display panel 12 are located on the side of the control base 1. The operation panel 11 is equipped with various function buttons, such as temperature setting buttons and start / stop buttons, facilitating input of commands by experimental personnel according to experimental needs. The display panel 12 uses an LCD screen to clearly display key parameters such as the current temperature value inside the furnace body 2 and the experimental running time, providing real-time feedback on the experimental status. Alternatively, a touch screen can be used to integrate the display panel 12 and the control panel as needed.

[0035] Furnace body 2 is a crucial component of the entire apparatus. It needs to be airtight to prevent deflagration of the coking coal during the coking process, which could lead to experimental failure. Therefore, furnace body 2 must have excellent sealing properties, and sealing structures such as sealing rings are required at the connection between furnace body 2 and door 24. In one embodiment, the inner wall of furnace body 2 is provided with a high-temperature resistant layer, a heat insulation layer, and an insulating layer stacked sequentially from the outside in. To facilitate observation of the reaction within furnace body 2, an observation window can be provided on door 24.

[0036] Furthermore, for safety reasons, the furnace body 2 needs to have good heat insulation and thermal insulation properties. The inner wall of the furnace chamber 23 within the furnace body 2 needs to be equipped with insulation and heat insulation structures. The furnace body 2 is placed on the control base 1, and its interior is hollowed out to form the furnace chamber 23. A rotatable tamping device 22 is installed inside the furnace chamber 23. This tamping device 22 is used to tamp the coking coal, ensuring that the coking coal is fully tamped before entering the furnace chamber 23, resulting in a more uniform distribution and meeting the needs of rapid reaction experiments, thus ensuring the efficiency and accuracy of the coking experiment. One side of the furnace body 2 has an openable door 24, which is controlled by operating a handle 6 connected to the door 24. The door 24 and the furnace body 2 are connected by several bearings to form a drawer-type connection structure. The operating handle 6 is inserted from the side of the furnace body 2 and connected to the door 24. This design not only makes the door 24 easy and smooth to open and close, but also facilitates cleaning of the interior of the furnace chamber 23 and inspection and maintenance of the tamping device 22 before and after the experiment.

[0037] The furnace door panel is cut using refractory bricks to ensure a seamless fit with the furnace opening. Small gaps are sealed with asbestos around the edges of the furnace door to ensure a sealed state throughout the coking experiment, while also providing good heat insulation and electrical insulation.

[0038] Heating component 4 can be a combustion chamber. After coking coal is loaded into tamping device 22, it is tamped. Tamping is completed when the density of coking coal is in the range of 0.95-1.1 g / cm3. The coking coal tamped by tamping device 22 then enters the furnace chamber 23 inside the furnace body 2. The combustion chamber transfers heat to the coking coal in the furnace chamber 23 through the inner wall of the furnace body 2. The coking coal first undergoes a drying process, in which the external moisture and some internal moisture contained therein evaporate upon heating. With the continuous input of heat, the temperature of the coking coal gradually rises and begins to enter the preheating stage. The temperature inside the furnace body 2 is collected by temperature control component 5 and controlled within the range of 900℃-1050℃ by the main control chip or main control circuit board in control base 1. This further heats the coal particles, causing them to gradually become loose and softened, producing a large amount of coking gas. In addition to combustible hydrogen, carbon monoxide, methane and other useful components, it is also mixed with a large amount of impurities, such as tar, naphthalene, hydrogen sulfide, ammonia, benzene and dust. At this time, the collecting component 3 collects various substances from above the furnace body 2 and discharges the treated gas outside the device.

[0039] Compared with existing technologies such as iron box experiments or 40kg coke oven experiments, this device can achieve coking effect in 4 hours, saving about 20 hours. The volatile matter content of the coke is about 1.20%, reaching the mature state of the coke. It can significantly shorten the coking experiment time, improve the experimental efficiency, and greatly reduce the labor intensity of personnel. It has important guiding significance for the procurement of raw materials by coal and coke enterprises.

[0040] In summary, this utility model provides an apparatus for a rapid coking experiment of coking coal. By setting a heating component 4 and a temperature control component 5 controlled by a control base 1 in the furnace body 2, the experimental temperature can be reliably controlled, thereby significantly improving the experimental efficiency. Furthermore, by setting a mobile phone component to collect harmful substances in the experimental exhaust, the pollution of the exhaust to the outside world can be significantly reduced.

[0041] In one embodiment, such as Figure 4 As shown, the collection component 3 includes a hollowed-out exhaust pipe 31, a cooling section 32 in the middle of the exhaust pipe 31, an exhaust section 33 at the upper end of the exhaust pipe 31, and a deposition section 34 below the exhaust section 33.

[0042] In one preferred embodiment, the cooling section 32 is provided with a cooling device electrically connected to the control base 1. In another preferred embodiment, the cooling section 32 is provided with a cooling coil or cooling fins.

[0043] Furthermore, the exhaust pipe 31 extends vertically upward from the upper surface of the furnace body 2. The upper end of the exhaust pipe 31 is provided with a bend, and the end of the bend is connected between the vertically arranged exhaust section 33 and the deposition section 34. The upper end of the exhaust section 33 is provided with an opening. The interior of the upper end of the deposition section 34 is provided with a filter screen, and the cross-sectional area of ​​the lower end of the deposition section 34 is larger than the cross-sectional area of ​​the exhaust section 33.

[0044] In this embodiment, the exhaust pipe 31 of the collecting component 3 extends vertically upward from the upper surface of the furnace body 2, and its upper end is provided with a bend. The end of the bend is connected to the vertically arranged exhaust section 33 and the deposition section 34. The upper end of the exhaust section 33 is provided with an opening.

[0045] The cooling section 32 in the middle of the exhaust pipe 31 is equipped with a cooling device electrically connected to the control base 1. The cooling device may be a semiconductor cooling chip, and the cooling power can be flexibly adjusted through the control base 1. The cooling section 32 is also equipped with a cooling coil made of copper with excellent thermal conductivity. The coolant circulates in the coil to further enhance the cooling effect.

[0046] The upper part of the deposition section 34 is equipped with a stainless steel filter to intercept solid impurities formed after cooling. The cross-sectional area of ​​the lower part of the deposition section 34 is intentionally designed to be larger than that of the exhaust section 33, thereby increasing the deposition space and improving the collection capacity of harmful substances. When the high-temperature exhaust gas generated during the experiment enters the exhaust pipe 31, it is first cooled in the cooling section 32, where the harmful substances condense. Some of these substances flow into the deposition section 34 along the cooling coil and pipe wall, while others are intercepted by the filter and remain in the deposition section 34. The purified gas is then discharged from the upper opening of the exhaust section 33, effectively reducing the pollution of the exhaust gas to the outside world.

[0047] In one embodiment, the furnace body 2 is also provided with an operating handle 6 connected to the door 24 for controlling the opening and closing of the door 24, and the tamping fastener 22 is fixedly connected to the door 24. Further, a drawer-type connection structure is formed between the door 24 and the furnace body 2 by a number of bearings, and the operating handle 6 is inserted from the side of the furnace body 2 and connected to the door 24.

[0048] like Figure 1 and Figure 2 As shown, parallel plates are respectively provided at the middle and lower ends of the door body 24. The tamping device 22 is connected to the upper surface of the parallel plate located in the middle, and the operating handle 6 is fixedly connected to the parallel plate at the lower end. The structure of the tamping device 22 is a concave bowl-shaped structure, and the overall shape can be a regular structure such as a cylinder or cuboid that is easy to tamping.

[0049] In one embodiment, the heating assembly 4 includes a plurality of heating elements electrically connected to the control base 1. The heating elements are disposed on the inner wall of the furnace chamber 23 in the furnace body 2 or on the inner side wall of the door 24. The temperature control assembly 5 includes thermocouples disposed on the inner side wall of the furnace chamber 23 in the furnace body 2.

[0050] In this embodiment, the heating assembly 4 includes several heating elements electrically connected to the control base 1. These heating elements can be flexibly arranged on the inner wall of the furnace chamber 23 in the furnace body 2, or on the inner side wall of the door 24. The heating elements are preferably high-temperature resistant, high-thermal-conductivity, and high-heat-efficiency resistance wire heating elements. By precisely regulating their heating power through the control base 1, precise control of the temperature inside the furnace chamber 23 can be achieved.

[0051] The temperature control component 5 mainly consists of thermocouples installed on the inner wall of the furnace chamber 23 within the furnace body 2. The thermocouples can sense temperature changes within the furnace chamber 23 in real time and convert the temperature signal into an electrical signal, which is then fed back to the control base 1. The control base 1 integrates a temperature control circuit and a microprocessor. The microprocessor compares and analyzes the electrical signal fed back by the thermocouples with the temperature value set by the operator on the control panel 11, and then automatically adjusts the heating power of the heating elements to ensure that the temperature within the furnace chamber 23 remains stable near the set value, thus ensuring the accuracy and stability of the experimental temperature.

[0052] Furthermore, K-type thermocouples can be selected. K-type thermocouples consist of a sensing element, mounting and fixing device, and junction box as the main components. K-type thermocouples can measure temperatures from -200℃ to 1300℃, covering most industrial scenarios. They can even support extreme environments of 1600℃ for short periods. They have the characteristics of wide measurement range, good linearity, high sensitivity, strong oxidation resistance, and high cost performance.

[0053] In addition, the inner wall of furnace body 2 is layered with a high-temperature resistant layer, a heat insulation layer, and an insulating layer from the outside to the inside. The high-temperature resistant layer uses high-temperature resistant materials such as ceramic fiber, which can withstand high-temperature environments without being damaged; the heat insulation layer uses high-efficiency heat insulation materials such as rock wool, which effectively reduces the loss of heat from the inside of furnace body 2 to the outside and reduces energy consumption; the insulating layer uses insulating ceramics and other materials to ensure the safety of operators and prevent electric shock accidents.

[0054] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0055] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
