Description

Technical Field

[0001] This application relates to the field of experimental coke oven technology, and in particular to a device for secondary treatment of raw coal gas from experimental coke ovens. Background Technology

[0002] A test coke oven is a process testing instrument used in metallurgical engineering and chemical engineering fields. It is used to test many factors that affect coke quality, such as fineness of grinding, particle size, and coking speed. The experimental results are applied to actual production and combined with conventional coal analysis to make the coal blending structure more reasonable and the cost effectively controlled.

[0003] During the coking process, the experimental coke oven produces a large amount of irritating and toxic raw coal gas, such as a mixture of water vapor, coal gas, and tar gas. The raw coal gas flows into the condenser through the rising pipe of the experimental coke oven. Water, which has undergone a low-temperature constant-temperature reaction, is introduced from the bottom of the condenser. Through water cooling, the tar in the raw coal gas is liquefied and separated. The liquefied tar flows down the condenser tube wall to the bottom. The valve at the bottom of the condenser is opened periodically to collect the tar in the waste tar barrel. The raw coal gas after the tar is separated by the condenser is then discharged through the pipeline after being burned by the ignition device and meets the emission standards.

[0004] Because the condensers are interconnected and the tar is liquefied and separated from the raw coal gas, some raw coal gas will overflow along with the tar during the process of opening the valve at the bottom of the condenser to separate and discharge the tar. Raw coal gas is flammable, irritating, toxic, and easily adsorbed, which seriously endangers human health and causes environmental pollution. At the same time, due to the open external space, the tar splashes during the discharge process, which is difficult to clean, damages the site hygiene, and does not meet production standards. Therefore, it needs to be improved. Utility Model Content

[0005] In order to create a closed space, prevent flue gas from escaping, and improve environmental and safety benefits, this application provides a device for secondary treatment of experimental coke oven raw gas.

[0006] The device for secondary treatment of experimental coke oven raw gas provided in this application adopts the following technical solution:

[0007] An apparatus for secondary treatment of raw coke oven gas includes an oil fume separation device. A tar tank is installed inside the oil fume separation device. Two condensers are installed above the oil fume separation device. One condenser has a test coke oven installed on one side, and a riser pipe is installed on the top of the test coke oven. A flexible metal hose and elbow for connecting to the condenser are installed on the riser pipe. A wall is installed on one side of the other condenser, and an ignition device is installed on the outside of the wall. The ignition device is connected to a flexible hose, which is connected to the oil fume separation device. A tee is installed on the top of the oil fume separation device, and both condensers are connected to the oil fume separation device through the tee.

[0008] By adopting the above technical solution, the bottom of the two condensers of the test coke oven is connected to a flexible hose. The two hoses are connected to the oil fume separation device through a tee. The oil fume enters the tar barrel through the outlet of the oil fume separation device. After the tar is discharged, the tar discharge valve is closed. The flue gas in the oil fume separation device is burned by the ignition device and discharged in compliance with the standards, thereby forming a closed space to prevent the flue gas from escaping and improve environmental protection and safety benefits.

[0009] Preferably, a small exhaust fan is provided on the hose.

[0010] By adopting the above technical solution, the small exhaust fan can remove the smoke from the oil fume separation device, while creating a slight negative pressure inside the device to prevent the smoke from overflowing due to poor sealing.

[0011] Preferably, both ends of the metal hose are provided with mating flanges, and the metal hose is connected to the riser pipe and elbow through the mating flanges.

[0012] By adopting the above technical solution, the installation of matching flanges can improve the ease of connection and installation between metal hoses, riser pipes, and elbows.

[0014] By adopting the above technical solutions, the installation stability of the test coke oven and condenser can be effectively improved.

[0015] Preferably, a valve is provided on the connecting pipe between the condenser and the tee.

[0016] By adopting the above technical solution, the valve can be set to discharge the separated tar into the tar tank of the oil fume separation device through a three-way valve, thereby realizing the flow control of tar.

[0017] Preferably, the upper interface of the oil fume separation device is provided with a threaded cover.

[0018] By adopting the above technical solution, the threaded cap can achieve a sealing function.

[0019] Preferably, both the inlet and outlet of the condenser are connected to a low-temperature constant-temperature reaction bath.

[0020] By adopting the above technical solution, a low-temperature constant-temperature reaction bath can be used for cooling, thereby ensuring the safety and stability of the system.

[0021] Preferably, a connecting pipe is provided between the two condensers.

[0022] By adopting the above technical solution, a connecting pipe can be installed between the two condensers to optimize heat exchange efficiency, balance system load, enhance operational flexibility, and ensure safe and stable operation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Connect the bottom of the two condensers of the test coke oven to the bottom of the hoses. Connect the two hoses to the oil fume separation device through the tee. The oil fume enters the tar barrel through the outlet of the oil fume separation device. After the tar is discharged, close the tar discharge valve. The flue gas in the oil fume separation device is burned by the ignition device and discharged in compliance with the standard, thus forming a closed space to prevent the flue gas from escaping and improve environmental protection and safety benefits.

[0025] 2. Flue gas has hazardous properties such as flammability, toxicity, irritation, and adsorption. This device prevents flue gas from escaping by forming a closed space, thus providing both environmental and safety benefits.

[0026] 3. Tar is sticky and can cause splashing during discharge. This device can prevent tar splashing and reduce the labor intensity of employees cleaning up tar. Attached Figure Description
