[0030] The method for measuring ammonia escape implemented according to the present invention includes the following steps:
[0031] 1. Connect the ammonia escape measuring device to determine the ammonia nitrogen content X2 (mg / L) of the blank dilute acid aqueous solution before absorbing the flue gas;
[0032] First, pour a volume V (unit: L) of a dilute acid aqueous solution with a PH value of less than 5 into the airtight container 10, and measure the ammonia nitrogen content X2 (mg / L) of the blank dilute acid aqueous solution before absorbing the flue gas; quickly connect the air duct 8. The valve 9 on the exhaust pipe 11 is closed. Put the filter element 2 into the filter device 1 and tighten it. The stainless steel intake pipe 4 is connected to the filter device 1 through the integral joint 3 and tightened; at the same time, the air guiding rubber hose 6 is connected with the air suction pump 7 and the integral joint 5 and the air tightness is checked.
[0033] 2. Start the ...
