Three-phase separation device for water quenching product and water quenching flue gas treatment system and method

Abstract

The invention discloses a three-phase separation device for a water quenching product and a water quenching flue gas treatment system and method. The three-phase separation device for a water quenching product comprises a reaction tank, a partition wall extending below the liquid level is arranged in the reaction tank, and the partition wall divides the reaction tank into a water quenching tank and a sediment tank which are connected through a flowing channel below the partition wall. A water quenching object is converted into water quenching flue gas and water quenching slag after entering the water quenching tank, the water quenching slag flows into the sediment tank through the flowing channel, and a gas collecting hood for collecting the water quenching flue gas is arranged above the water quenching tank. The upper parts of the water quenching tank and the sediment tank are separated, so that water quenching flue gas generated by the water quenching tank can be collected by the gascollecting hood in a more centralized manner. The water quenching tank is communicated with the lower part of the sediment tank, so that the temperature of the water quenching slag can be fully reduced in the process of flowing to the sediment tank, and the liquid in the sediment tank and the liquid in the water quenching tank can be subjected to heat transfer, thereby reducing the temperature ofthe liquid in the water quenching tank and improving the water quenching efficiency.

Description

technical field [0001] The invention relates to the technical field of water quenching, in particular to a three-phase separation device for water quenching products and a water quenching flue gas treatment system and method. Background technique [0002] Using water as the quenching agent can make the liquid high-temperature slag be rapidly cooled and split into small particles of water-quenched slag, which can be directly used as building materials without crushing. However, a large amount of water-quenched flue gas with high temperature and high pressure characteristics will be produced during the water quenching process. On the one hand, if these water-quenched flue gases are not properly handled in time, there will be explosion hazards. On the other hand, the collected water-quenched flue gas There is no efficient and energy-saving treatment technology for the resulting environmental problems. Contents of the invention [0003] The first technical problem to be solve...
