Abstract
A scrubber for removing pollutants from a gas comprising a housing for conducting the gas therethrough, a mechanism for introducing pollutant-reactive filtering agent into the housing, a sump for collecting the filtering agent and having a first volume, and an intermediate sump for collecting the filtering agent and channeling the filtering agent into the sump, the intermediate sump having a second volume that is less than the first volume.
Claims12
A scrubber for removing pollutants from a gas and having an inlet for receiving the gas and an outlet for emitting the gas, the scrubber comprising:
- a housing coupled with the gas intermediate the inlet and the outlet;
- a source of pollutant-reactive filtering agent;
- a pump coupled to the source of filtering agent and to the housing in fluid communication;
- at least one dispersing element for communicating the filtering agent from the pump into the housing;
- a sump for collecting the filtering agent, the sump having a first volume;
- an intermediate sump for collecting the filtering agent and channeling the filtering agent into the sump, the intermediate sump having a second volume that is less than the first volume;
- and
- means for monitoring the concentration of filtering agent at the intermediate sump and for actuating the pump for altering the amount of filtering agent supplied to the housing in response thereto.
A method of removing pollutants from a gas comprising steps of:
- providing a housing having an inlet for receiving gas and an outlet for emitting gas;
- introducing an amount of pollutant-reactive filtering agent into the housing;
- collecting the filtering agent with a sump having a first volume;
- collecting filtering agent with an intermediate sump having a second volume that is less than the first volume;
- monitoring the concentration of filtering agent at the intermediate sump;
- and
- when the concentration of the filtering agent at the intermediate sump falls outside a predetermined threshold, altering the amount of filtering agent being introduced into the housing.
A scrubber for removing pollutants from a gas and having an inlet for receiving the gas and an outlet for emitting the gas, the scrubber comprising:
- a housing coupled with the gas intermediate the inlet and the outlet;
- a source of a pollutant-reactive filtering agent;
- means for introducing the filtering agent into the housing;
- a sump for collecting the filtering agent, the sump having a first volume;
- an intermediate sump for collecting the filtering agent and channeling the filtering agent into the sump, the intermediate sump having a second volume that is less than the first volume;
- and
- means for monitoring the concentration of filtering agent at the intermediate sump and for actuating the pump for altering the amount of filtering agent supplied to the housing in response thereto.
The scrubber of claim 11, the means comprising:
- a pump coupled to the source of filtering agent and to the housing in fluid communication;
- and
- at least one dispersing element for communicating the filtering agent from the pump into the housing.
