Abstract
Provided are a filler-integrated cooler having a cooler body with cooling space, gas inlet and outlet and communicated with bottom and top of the cooling space, a cooling pipe in the cooling space between the gas inlet and outlet to make cooling fluid from a cooling-fluid inlet go around in the cooling space and discharge the same through a cooling-fluid outlet and a filler vertically partitioning the cooling space into portions with the gas inlet and outlet, a nozzle arranged above in the cooling space, a drain circulator supplying drain in a drain reservoir at inner bottom of the cooling space through a drain outlet to the nozzles, using a pump, and an alkaline-agent addition unit to add an alkaline agent to drain.
Claims7
An impurity removal device for water-containing gas connected to an impurity separator including a compressor to which gas is introduced from an oxyfuel combustor and an aftercooler for cooling the gas compressed by the compressor to discharge condensed drain, said impurity removal device comprising:
- a cooler with a cooling space, and a drain reservoir in an inner bottom of said cooling space;
- a filler arranged in said cooling space to vertically partition a space above said drain reservoir;
- a gas inlet connected to said cooler to communicate with an inner underside of said cooling space defined by said filler for introduction of the water-containing gas for said aftercooler;
- a gas outlet connected to said cooler to communicate with an inner upside of said cooling space defined by said filler;
- a cooling pipe arranged in the inner underside of said cooling space defined by said filler and through which cooling fluid passes;
- a cooling fluid inlet on a first end of said cooling pipe;
- a cooling fluid outlet on a second end of said cooling pipe;
- nozzles arranged in the inner upside of said cooling space defined by said filler;
- a drain circulator with a drain outlet on a bottom of said cooler for discharge of drain from said drain reservoir, a circulation flow passage for communication of said drain outlet with said nozzles, and a pump arranged in said circulation flow passage, thereby injecting the drain through the nozzles;
- and
- an alkaline agent addition unit with a flow passage communicated with said circulation flow passage for adding an alkaline agent to the drain.
