Description

Technical Field

[0001] This utility model belongs to the field of dry quenching coke production technology, and in particular relates to a device for reducing condensate in the dry quenching coke venting pipeline. Background Technology

[0002] Dry quenching refers to a method of cooling red-hot coke using inert gas. During the dry quenching process, red-hot coke is loaded from the top of the dry quenching furnace, and low-temperature inert gas is blown into the red-hot coke layer in the cooling section of the dry quenching furnace by a circulating fan to absorb the sensible heat of the red-hot coke. The cooled coke is then discharged from the bottom of the dry quenching furnace.

[0003] During dry quenching operation, if malfunctions such as furnace tube leakage or the addition of raw coke occur, the pressure in the pre-storage chamber will be high. If the pressure in the pre-storage chamber cannot be controlled within the specified range by the pre-storage chamber pressure regulating valve, it is necessary to open the dry quenching furnace's venting device to release pressure and ensure the safe retreat of the dry quenching furnace. However, during normal operation of the dry quenching unit, if the gas in the dry quenching furnace's venting pipe is not flowing, the water entrained in the circulating gas will condense, affecting the stable operation of the dry quenching furnace and damaging equipment such as expansion joints.

[0004] During normal operation of existing dry quenching coke units, a large amount of condensate will be generated in the air vent pipe of the dry quenching furnace. If the condensate is not drained for a long time, it will accumulate and enter the dry quenching furnace, affecting the composition of the circulating gas in the dry quenching furnace and the stable operation of the dry quenching coke units. Utility Model Content

It aims to solve the problem that during the normal operation of existing dry quenching coke equipment, a large amount of condensate is generated in the dry quenching furnace venting pipeline. If the condensate is not drained for a long time, it will accumulate and enter the dry quenching furnace, affecting the composition of the circulating gas in the dry quenching furnace and the stable operation of the dry quenching coke equipment.

[0022] Please see Figure 1-3The present invention provides an embodiment of a device for reducing condensate in a dry quenching coke venting pipe. The device includes a dry quenching furnace 1 and a circulating water tank 2. The circulating water tank 2 is used to store water for heating the inert gas used in the dry quenching process. An electric cylinder 4 is fixed to the top of the dry quenching furnace 1, and a feed material 5 is fixed to the top of the electric cylinder 4. A coke canister 7 is attached to the top of the feed material 5. An air inlet pipe 3 is inserted into the side wall of the dry quenching furnace 1. Inert gas is filled in a pre-storage chamber and connected to the air inlet pipe 3 for gas supply. Both the inert gas and the pre-storage chamber are existing technologies and will not be described in detail here. The dry quenching furnace 1 is used to fill coke and inert gas, thereby achieving a reduction in coke condensate. In the dry quenching furnace 1, a vent pipe 8 is inserted into the side wall away from the inlet pipe 3 for exhaust and pressure reduction. A slot 17 is opened at the top inner end of the dry quenching furnace 1, which is connected to the inlet pipe 3, the vent pipe 8, and the feed material 5 in sequence. A slot 28 is opened inside the dry quenching furnace 1 near the bottom of slot 17 for loading coke that is being cooled. A slot 39 is opened below the slot 28 for loading coke that is being cooled. A slot 4 20 is opened at the bottom inner end of the dry quenching furnace 1. A discharge port 14 is inserted into the bottom end of the dry quenching furnace 1. The feed material 5, slots 17, 28, 39, and the slot 4 are connected to the dry quenching furnace 1. Four valves 20 are connected sequentially via valve plates. Coke tank 7 is transported by a hoist to transport heated coke, improving the efficiency of coking coal circulation. A second vent pipe 9 is installed at the other end of vent pipe 18. Vent pipe 18 forms a 10-degree angle with the horizontal line. Vent pipe 18 and vent pipe 29 are L-shaped. Vent pipe 29 is installed vertically with its opening facing upwards, improving the stability of condensate flow. A valve 2 13 is installed in the middle of vent pipe 18. A condenser pipe 10 is inserted into the bottom of vent pipe 18. A valve 12 is installed in the middle of condenser pipe 10. A condenser cylinder 11 is fixed on the side wall of condenser pipe 10 near valve 12. 11 is connected to the inside of the condenser tube 10. The bottom end of the condenser tube 10 is connected to the top end of the circulating water tank 2. When the internal air pressure of the slot 17 is too high, the operator can open the valve 2 13 to connect the slot 17 and the vent pipe 2 9, thereby venting the high-temperature and high-pressure gas. When the high-temperature gas comes into contact with the inner wall of the vent pipe 2 9, condensate is generated. The condensate flows into the inside of the condenser tube 10 along the vent pipe 18. The operator opens the valve 12 to discharge the stored condensate into the circulating water tank 2 for water circulation, thereby preventing the condensate from flowing back into the inside of the slot 17, thus improving the stability of dry quenching coke production.

[0023] A dust removal pipe 6 is fixedly installed at the top of material type 5. An isolation net 21 is fixedly installed through the inner wall of material type 5. The dust removal pipe 6 is connected to a blower to transport and discharge the dust filtered by the isolation net 21, which improves the convenience of dust removal. A connecting pipe 15 is inserted into the side wall of the second vent pipe 9. The other end of the second vent pipe 9 is connected to the air inlet pipe 3. A regulating valve 16 is installed in the middle of the connecting pipe 15. Opening the regulating valve 16 can transport heated nitrogen into the interior of the second vent pipe 9, preheating the second vent pipe 9 and thus reducing the condensate formed when the second vent pipe 9 discharges high-temperature gas. The connecting pipe 15 is a nitrogen pipeline with a diameter of DN25, which is connected at the bend of the second vent pipe 9. The regulating valve 16 is used to control the nitrogen content in the dry quenching coke vent pipe. The end of the second vent pipe 9 is interlocked with the pre-storage chamber pressure setting by setting a nitrogen electric valve. When the pre-storage chamber pressure rises to 300Pa and lasts for 1 minute, the nitrogen electric valve is automatically closed.

[0024] Working Principle: When using this device for reducing condensate discharge from the dry quenching coke venting pipeline, the operator first connects an external power source. The operator then uses a hoist to lift the heated coking coal from the top and clamp it onto the top of feed type 5. Opening the bottom valve plate of the coke pot 7 allows the coking coal to enter the interior of feed type 5. The coking coal sequentially passes through feed type 5, electric cylinder 4, and slot 17 into slot 2 18. The air inlet pipe 3 is used to deliver preheated nitrogen into slot 17, thereby cooling the coking coal. The dry quenching furnace 1, coke pot 7, and hoist are all existing components. The technology will not be elaborated here. When the internal air pressure of slot 17 is too high, the operator can open valve 213 to connect slot 17 and vent pipe 29, thereby venting the high-temperature and high-pressure gas. When the high-temperature gas comes into contact with the inner wall of vent pipe 29, condensate is generated. The condensate flows into the interior of condenser pipe 10 along vent pipe 18. The operator opens valve 12 to discharge the stored condensate into circulating water tank 2 for water circulation, thereby preventing condensate from flowing back into slot 17 and improving the stability of dry quenching production.

[0025] Secondly, when pressure relief is required, the operator can open the regulating valve 16 in advance to deliver heated nitrogen into the interior of the vent pipe 2 9, thereby preheating the vent pipe 2 9 and reducing the condensate formed when the vent pipe 2 9 discharges high-temperature gas.
