[0002] Coke melting loss reaction refers to the chemical reaction between coke and gaseous media (such as CO2, water vapor, etc.) under high temperature conditions, resulting in coke quality loss and structural deterioration. During the coke melting loss reaction, coke and pulverized coal are introduced into a heater, carbon dioxide is added to the heater and the reaction is heated, and the gas in the heater is released from the exhaust pipe. Because the heater continuously heats the coke and pulverized coal, the temperature of the gas released from the exhaust pipe is high, making it inconvenient to process the gas. Utility Model Content

[0005] Design a coke melting reaction device, including a shell, a heating container connected inside the shell, an end cap connected to the upper end of the heating container, a temperature measuring element passing through the end cap, a perforated plate fixedly connected inside the heating container, an air inlet pipe connected to the bottom end of the heating container, a connecting pipe connected to the upper end of one side of the heating container, a cooling mechanism connected to one end of the connecting pipe, and the cooling mechanism fixedly connected to the shell.
[0006] The cooling mechanism includes a mounting plate, which is fixedly connected to the housing. A box is fixedly connected to the mounting plate, and a heat exchange tube is connected inside the box. An air outlet pipe is connected to the bottom of one side of the box.
[0007] Preferably, the bottom of the heating container is provided with a layer of corundum spheres.
[0008] Preferably, the housing is coated with an anti-corrosion layer.
[0009] Preferably, a filtering mechanism is connected to the bottom end of the end cap. The filtering mechanism includes two parallel connecting rods, which are fixedly connected to the bottom end of the end cap. Each connecting rod has a grooved post slidably connected to it. One end of each connecting rod is fixedly connected to an anti-detachment block, and each anti-detachment block is slidably connected to a corresponding grooved post. One end of each grooved post is fixedly connected to the same first fixing ring. The first fixing ring cooperates with the heating container. A filter screen is connected to the inner wall of the first fixing ring. A through hole is opened in the center of the filter screen, and a second fixing ring is connected to the through hole. The temperature sensing element passes through the second fixing ring.
[0010] Preferably, limit rods are fixedly connected to both sides of the bottom end of the first fixing ring.
[0011] The coke melting loss reaction device proposed in this utility model has the following advantages:
[0012] After the heating container is started, coke and pulverized coal are heated. Carbon dioxide and nitrogen are introduced through the inlet pipe. The gas in the heating container is introduced into the box through the connecting pipe. Cold water flows into the heat exchange tube. The hot gas in the box comes into contact with the heat exchange tube and exchanges heat to cool the hot gas. The cooled gas is released from the outlet pipe and passes through the heat exchange tube to exchange heat to cool the hot gas, thus facilitating the treatment of the emitted gas.

The box 82 is coated with an anti-corrosion layer. A heat exchange tube 83 is connected inside the box 82. An air outlet pipe 84 is connected to the bottom of one side of the box 82.
[0021] Work process:
[0022] Open the end cap, first add coke to the heating container 2, the coke falls onto the perforated plate 5, then add pulverized coal, the pulverized coal falls onto the coke, and the end cap seals the heating container 2. One end of the temperature measuring element 3 passes through the end cap and is inserted into the coke. After the heating container 2 is started, it heats the coke and pulverized coal. Carbon dioxide and nitrogen are introduced through the inlet pipe 6. The introduced gas passes through the corundum ball layer 4 and the perforated plate 5 and comes into contact with the coke. The gas in the heating container 2 is introduced into the box 82 through the connecting pipe 7. Cold water flows into the heat exchange tube 83. The hot gas in the box 82 comes into contact with the heat exchange tube 83 and exchanges heat to cool the hot gas. The cooled gas is released from the outlet pipe 84 and exchanges heat to cool the hot gas through the heat exchange tube 83, thus facilitating the treatment of the emitted gas.
[0023] Example 2: Refer to Figure 4As another preferred embodiment of this utility model, the difference from embodiment 1 is that a filter mechanism 9 is connected to the bottom end of the end cap. The filter mechanism 9 includes two parallel connecting rods 91, which are fixedly connected to the bottom end of the end cap. Each connecting rod 91 is slidably connected to a grooved post 92, and one end of each connecting rod 91 is fixedly connected to an anti-detachment block. Each anti-detachment block is slidably connected to a corresponding grooved post 92. One end of each grooved post 92 is fixedly connected to the same first fixing ring 93. The first fixing ring 93 cooperates with the heating container 2. A filter screen 94 is connected to the inner wall of the first fixing ring 93. A through hole is opened in the center of the filter screen 94. A second fixing ring 95 is connected to the top, and the temperature measuring element 3 passes through the second fixing ring 95. Limiting rods 96 are fixedly connected to both sides of the bottom end of the first fixing ring 93. The end cap is fixed to the heating container 2, and the end cap fixes the connecting rod 91. The connecting rod 91 is connected to the grooved column 92 through the anti-detachment block. The grooved column 92 is connected to the first fixing ring 93. The first fixing ring 93 fixes the filter screen 94. The first fixing ring 93 contacts the coke through the limiting rod 96, so that a certain distance is created between the filter screen 94 and the coke. The gas in the heating container 2 passes through the filter screen 94. The filter screen 94 filters the dust particles in the gas. The filtered gas is introduced into the connecting pipe 7 to reduce the dust particles in the emitted gas.
