Problems solved by technology
The problem with this method is that the dust is collected together by the turn-back tray and the settler, and the design is more complicated; and in order to avoid negative pressure, a one-way valve and a solenoid valve are specially used to avoid negative pressure accidents caused by it.

Embodiment Construction
[0056] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0057] Such as figure 1 As shown, the water-jet closed coke quenching system of the embodiment of the present invention includes a coke quenching tower 10, a steam condensation absorption system, a non-condensable gas recovery system, and a powder coke precipitation recovery system, wherein the steam condensation absorption system includes a steam condensation tower 24, Gathering hood 21, connecting pipe 23, injection device 22 and spraying device 25; gas collecting hood 21 is closed and installed on the top of coke quenching tower 10, and connecting pipe 23 is used to connect gas collecting hood 21 and steam condensation tower 24. The communication pipe 23 is inclined downward about 30°-45°, so that the smoke gas containing water vapor, non-condensable gas and a large amount of dust f...

The invention discloses a water jet closed coke quenching system. The water jet closed coke quenching system comprises a coke quenching tower, a steam condensation and absorption system, a non-condensable gas recovery system and a fine coke precipitation and recovery system, wherein the steam condensation and absorption system comprises a steam condensation tower, a gas-collecting hood, a communicating pipe, a jet device and a spraying device; the gas-collecting hood is arranged at the top of the coke quenching tower, the communicating pipe is connected between the steam condensation tower and the gas-collecting hood, the jet device is arranged in the communicating pipe, the spraying device is arranged at the top of the steam condensation tower, and the steam condensation tower is communicated with the fine coke precipitation and recovery system through a first pipeline; and the non-condensable gas recovery system comprises a gas-liquid separator, a non-condensable gas recovery device and a jet flow device, the non-condensable gas recovery device is communicated with the steam condensation tower through a non-condensable gas guide pipe, the lower part of the non-condensable gas recovery device is communicated to the gas-liquid separator, and the jet flow device is arranged on the non-condensable gas recovery device and is used for jetting flow into the non-condensable gas recovery device. The water jet closed coke quenching system disclosed by the invention has the advantages of simple process flow and low capital construction investment, and can solve non-condensable gas produced by wet coke quenching and eliminate atmospheric pollution.
Description
technical field [0001] The invention relates to a water jetting closed coke quenching system, which utilizes the Venturi principle to generate negative pressure in the entire coke quenching system, and belongs to the technical field of wet coke quenching. Background technique [0002] The traditional coke quenching method is also called open wet coke quenching. The coke quenching car equipped with red coke is cooled by spraying water in the coke quenching tower. The top is vented to atmosphere. At present, most independent coking plants in my country adopt this coke quenching method. The reason why this method is widely used is that the process is simple, but there are two fatal shortcomings. One is that the sensible heat of red coke cannot be recycled; the other is that it causes serious pollution to the atmosphere. However, coke CDQ has the problems of high investment, high energy consumption, complex process and high technical difficulty, and large-scale promotion is no...
