Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, and more specifically to a sewage discharge structure of a water seal device in a large thallium of a heating furnace. Background Art

[0002] Oil shale, also known as kerogen, is a sedimentary rock containing organic matter. It is generally a high-mineral content sapropelite, a low calorific value solid fossil fuel, and its color ranges from light gray to dark brown. The organic matter contained in oil shale is a high-molecular polymer insoluble in organic solvents, called kerogen or kerogen. The inorganic minerals of oil shale mainly include quartz, kaolin, clay, mica, carbonate rock, and pyrite. The content of inorganic minerals in oil shale is usually about 50%-85%, which is higher than its organic matter content. Oil shale is an important raw material for "artificial petroleum", that is, "synthetic liquid fuel". After heating and dry distillation under air-tight conditions, the kerogen contained in it decomposes to produce shale oil, dry distillation gas and shale semi-coke. Shale oil can be used as fuel oil, and can also be further processed to produce gasoline, diesel and chemicals. Oil shale can also be used as boiler fuel for combustion to produce gas and generate electricity. In the field of oil shale distillation equipment, a heating furnace is required. In order to prevent the backflow or leakage of oil shale distillation gas and liquid and to ensure the safe and stable operation of the system and equipment, a water seal device is often installed.

[0003] After searching, the utility model patent with announcement number CN203079907U discloses a water seal device inside a large lead of a heating furnace, which includes a furnace body, wherein two water inlet pipes are introduced from the side wall of the furnace body, and one end of the water inlet pipe located inside the furnace body is respectively connected to the lower end of a jacket, and the jacket is arranged in a vertical direction, and an inclined water outlet is provided at the top of the jacket. However, the above patent still has the following shortcomings: the water used for water seal in the heating furnace will cause scale to form on the inner wall of the water seal, which is not convenient for cleaning the scale, and it is also not convenient for discharging the sewage at the water seal. For this reason, we propose a sewage discharge structure for a water seal device inside a large lead of a heating furnace. Utility Model Content
