Apparatus and method for rapid cooling of high temperature gas

A system for rapid cooling of a high temperature gas, comprising an apparatus for rapid cooling of a high temperature gas, and further comprising a gas-and-liquid separation device, a liquid delivery device, and a heat transfer device;

• wherein the apparatus for rapid cooling of a high temperature gas comprises:
• a plurality of cylindrical housings connected to one another;
• a jacket on an outer side of any one of the plurality of cylindrical housings;
• an inner cylinder disposed at least in an interior of a first cylindrical housing of the plurality of cylindrical housings;
• a heat insulation gasket configured to seal the first cylindrical housing and a top of the inner cylinder in the interior of the first cylindrical housing;
• inner members distributed along a wall of any one of the plurality of cylindrical housings, wherein the inner members are configured to communicate an interior of the jacket with an interior of any one of the plurality of cylindrical housings, and configured to distribute a liquid in the interior of the jacket to the interior of any one of the plurality of cylindrical housings;
• a high temperature gas inlet disposed on the heat insulation gasket;
• a gas and liquid phase outlet disposed on a bottom of the cylindrical housing of a bottom of a last cylindrical housing of the plurality of cylindrical housings;
• and
• a coolant inlet and outlet connected to the interior of the jacket, and
• wherein an outlet of the apparatus for rapid cooling of the high temperature gas is connected to an inlet of the gas-and-liquid separation device through a pipe, the gas-and-liquid separation device has a gas outlet and a liquid outlet, and a liquid of the gas-and-liquid separation device is delivered to the heat transfer device through the liquid delivery device and returned to an inlet of a jacket of the apparatus for rapid cooling of the high temperature gas after being delivered out of the heat transfer device.

A method for rapid cooling of a high temperature gas using an apparatus for rapid cooling of a high temperature gas, wherein the apparatus for rapid cooling of a high temperature gas comprises:

• a plurality of cylindrical housings connected to one another;
• a jacket on an outer side of any one of the plurality of cylindrical housings;
• an inner cylinder disposed at least in an interior of a first cylindrical housing of the plurality of cylindrical housings;
• a heat insulation gasket configured to seal the first cylindrical housing and a top of the inner cylinder in the interior of the first cylindrical housing;
• inner members distributed along a wall of any one of the plurality of cylindrical housings, wherein the inner members are configured to communicate an interior of the jacket with an interior of any one of the plurality of cylindrical housings, and configured to distribute a liquid in the interior of the jacket to the interior of any one of the plurality of cylindrical housings;
• a high temperature gas inlet disposed on the heat insulation gasket;
• a gas and liquid phase outlet disposed on a bottom of a last cylindrical housing of the plurality of cylindrical housings;
• and
• a coolant inlet and outlet connected to the interior of the jacket, and
• the method comprising:
• a strongly corrosive solid-containing high temperature gas entering the apparatus for rapid cooling of the high temperature gas and being cooled in an interior of the first cylindrical housing by a liquid entering the apparatus;
• the gas being further mixed with the liquid entering the apparatus and cooled in an interior of a cylindrical housing at a next stage;
• and a gas phase and a liquid phase entering a gas-and-liquid separation device, the gas phase being cooled leaving the gas-and-liquid separation device, part of the liquid phase being extracted, and part of the liquid phase being cooled and then returning to the apparatus for rapid cooling of the high temperature gas.
