Abstract
An exhaust gas cooling system includes, an exhaust gas-processing tower provided at a lower portion with an inlet port for an exhaust gas containing moisture and also provided at an upper interior space with a spray member, a circulating passageway for circulating exhaust gas-processing water from the bottom of the exhaust gas-processing tower to the spray member, a heat exchanger provided at a midway of the circulating passageway for, cooling the exhaust gas-processing water, a cooling tower for generating cooling water by taking advantage of the evaporation heat of water, thereby allowing the cooling water to circulate through the heat exchanger, and a water supply passageway for supplying the exhaust gas-processing water passing through circulating passageway to the cooling tower as part of-make-up water.
Claims6
An exhaust gas cooling system, comprising:
- an exhaust gas-processing tower provided at a lower portion with an inlet port for an exhaust gas containing moisture and also provided at an upper interior space with a spray member;
- a circulating passageway for circulating an exhaust gas-processing water from a bottom portion of said exhaust gas-processing tower to said spray member;
- a heat exchanger provided at a portion of said circulating passageway for cooling the exhaust gas-processing water;
- a cooling tower for generating cooling water by taking advantage of the evaporation heat of water, thereby allowing the cooling water to circulate passing through said heat exchanger;
- and
- a water supply passageway for supplying said exhaust gas-processing water passing through said circulating passageway to said cooling tower as a portion of make-up water.
An exhaust gas cooling system, comprising:
- an exhaust gas-processing tower provided at a lower portion with an inlet port for an exhaust gas containing moisture and also provided at an upper interior space with a spray member;
- and
- a cooling tower for cooling an exhaust gas-processing water existing at a bottom portion of said exhaust gas-processing tower by taking advantage of the evaporation heat of water, thereby allowing the water thus cooled to be fed to a spray member of said exhaust gas-processing tower.
