Detailed Description
The utility model provides a protection device of a tail gas analysis instrument in chlorination production, as shown in figure 1, comprising a gas marking bottle 1, a gas-liquid separator 2, a drying device 4 and a filtering device 5 which are connected in sequence from the gas coming direction;
the gas standard bottle 1 is internally provided with a chlorine gas detection agent solution, the chlorine gas detection agent solution is preferably a potassium iodide solution, tail gas to be detected firstly enters the gas standard bottle, is cooled by the chlorine gas detection agent solution, and meanwhile, when chlorine gas leaks from the chlorination furnace, the potassium iodide solution can timely detect the chlorine gas and generate color change so as to remind detection personnel to timely treat the problem of chlorine gas leakage from the chlorination furnace.
Preferably, a first air inlet pipe and a first air outlet pipe are arranged on the standard gas bottle, the first air inlet pipe extends into the bottom of the chlorine gas detection agent solution, the air outlet pipe is positioned at the top of the standard gas bottle, and the pipe opening of the air outlet pipe is positioned above the chlorine gas detection agent solution. The air inlet pipe is arranged deep to the bottom of the chlorine gas detection agent solution, so that the tail gas to be detected can be fully contacted with the chlorine gas detection agent solution, and the tail gas is fully cooled and whether the chlorine gas is contained or not is detected. And whether the sampling of the tail gas to be detected is smooth or not can be judged by observing the size and the speed of the bubbles in the chlorine gas detection agent solution.
The gas-liquid separator 2 is used for removing moisture in the tail gas to be detected from the standard gas bottle; preferably, the middle upper part of the gas-liquid separator is provided with a second air inlet pipe and a second air outlet pipe, and the bottom of the gas-liquid separator is provided with a sewage discharge pipeline and a sewage discharge valve 3.
