Patent ID: 7374604

Claim:
a system for flue gas treatment, comprising: a quench tower to receive a first flue gas, decrease the temperature of said first flue gas to a first temperature via a first scrubbing solution, and remove a plurality of first flue gas particles with a first diameter from said first flue gas; a fabric filter to remove a plurality of second flue gas particles with a second diameter from said first flue gas with said first temperature, whereupon a second flue gas with said first temperature is formed; a first control module comprising a first flow rate detecting device to detect the flow rate of said first flue gas, a first humidity detecting device to detect the humidity of said first flue gas, a first temperature detecting device to detect the temperature of said first flue gas, a central processing device, a first control valve, a second humidity detecting device to detect the humidity of a cooling gas, a second temperature detecting device to detect the temperature of said cooling gas and a second control valve, wherein said first central processing device receives a first flow rate signal generated from said first flow rate detecting device, a first humidity signal generated from said first humidity detecting device, a first temperature signal generated from said first temperature detecting device, a second humidity signal generated from said second humidity detecting device and a second temperature signal generated from said second temperature detecting device, and generates an instant first and second control signals, whereupon said first control valve receives said first control signal to lead said first scrubbing solution into said quench tower and adjust the amount of said first scrubbing solution, and said second control valve receives said second control signal to lead said cooling gas into said fabric filter and adjust the amount of said cooling gas; a wet scrubbing tower to decrease said first temperature of said second flue gas to a second temperature via said first scrubbing solution, and to remove a plurality of third flue gas particles with a third diameter from said second flue gas, whereupon a second scrubbing solution is formed; and a regeneration module to treat said second scrubbing solution to form a third scrubbing solution, wherein said third scrubbing solution is then fed back to said quench tower and said wet scrubbing tower to substitute said first scrubbing solution for repeating what originally performed via said first scrubbing solution.
