a coalescer 12, the coalescer 12 comprising a coalescing inlet 121, a first coalescing outlet 122, and a second coalescing outlet 123;
an analyzer 17
Wherein,
the nitrogen inlet 1 is connected with the gas-water mixture inlet pipe 101 through a nitrogen shut-off valve 3, a pressure reducing valve 4 and a nitrogen flow meter 5 in sequence, the circulating water inlet 2 is connected with the gas-water mixture inlet pipe 101 through a circulating water cut-off valve 6, a water filter 7 and a circulating water flowmeter 8 in turn, the sample gas outlet pipe 102 is connected to the cooling inlet 111, the wind cooler drain pipe 103 is connected to the cooling liquid port 113, the cooling outlet 112 is connected to the coalescer inlet 121, the second coalescer outlet 123 is connected to the coalescer drain 104, the first coalescing outlet 122 is connected to the analyzer 17 via a sample flow meter 13, the overflow port 105 is connected to a water-sealed pipe 15, an exhaust pipe 16 is connected to the upstream of the water-sealed pipe 15, downstream of the water seal 15 a main discharge 14 is connected, the sewage discharge 108 being connected to the main discharge 14 via a sewage discharge valve 9.

The vent 109 is a second distance H2 from the overflow 105. The value of this second distance H2 is dependent on the particular size of the on-line stripper tank 10.
The exhaust hole 109 has an oblong hole shape.
The operation of the system for on-line analysis of trace toxic gases dissolved in circulating water is described below.
Nitrogen enters the system from a nitrogen inlet 1, is subjected to pressure reduction and flow limitation through a nitrogen stop valve 3, a pressure reducing valve 4 and a nitrogen flowmeter 5 and then enters a gas-water mixture inlet pipe 101; meanwhile, the circulating water enters the gas-water mixture inlet pipe 101 from the circulating water inlet 2 after being filtered and limited by the circulating water stop valve 6, the water filter 7 and the circulating water flowmeter 8, at the moment, the nitrogen and the circulating water are preliminarily mixed in the gas-water mixture inlet pipe 101, and the mixture immediately enters the online gas stripping tank 10.
After the mixture of the nitrogen and the circulating water enters the inner shell 107 of the online gas stripping tank 10, the liquid sinks and enters an interlayer between the inner shell 107 and the outer shell 106 through the flow opening 110 until the interlayer is filled and is discharged from the overflow opening 105, in the process, the nitrogen and the circulating water are further mixed in the inner shell 107 through the height of the first distance H1, the glass ring enables the gas and the liquid to be mixed more fully, and the nitrogen can more easily carry out trace gas in the circulating water. On the other hand, the gas in the mixture floats upwards until the third height space of the inner shell 107 with the distance H3 is filled, and the surplus gas is discharged into the interlayer between the inner shell 107 and the outer shell 106 through the exhaust hole 109 and then rises to the overflow port 105 to be discharged. During the gas floating up to fill the height space of the third distance H3, the nitrogen gas is thoroughly mixed with the gas present in trace amounts taken from the circulating water by the action of the glass ring.
In addition, the outer shell 106 is provided with a reducing shape with a wider upper part and a narrower lower part, so that the influence on the liquid level at the top part is small in the rising process of bubbles formed by discharging the surplus gas in the inner shell 107 through the vent hole 109, and the gas pressure at the upper part of the inner shell 107 is kept at the water seal pressure at the height of H2 steadily all the time.
The liquid and the surplus gas mixture discharged from the overflow port 105 are split at the tee joint of the pipeline, the gas is recycled from the A to the exhaust pipe 16, the liquid is recycled from the B to the main liquid discharge pipe 14 through the water seal pipe 15, the water seal pipe 15 is set to be in a U-shaped structure, the effect of liquid discharge and gas blockage is achieved, and the gas can be effectively prevented from entering the main liquid discharge pipe 14.
The mixed gas with the stable pressure at the upper part of the inner shell 107 of the online stripping tank 10 enters the air cooler 11 through the sample gas outlet pipe 102 for cooling and condensation, and condensed water is discharged into a jacket between the outer shell 107 and the inner shell 106 of the online stripping tank 10 through the air cooler liquid discharge pipe 103, wherein the insertion depth of the liquid discharge pipe is the same as that of the gas-water mixture inlet pipe 101, so that the pressure is stabilized. The mixed gas primarily dried by the air cooler 11 enters the coalescer 12 for secondary dewatering and drying, and the removed water is discharged into a jacket between an outer shell 107 and an inner shell 106 of the online gas stripping tank 10 through a coalescer liquid discharge pipe 104, wherein the depth of the liquid discharge pipe is the same as that of the gas-water mixture inlet pipe 101 so as to stabilize the pressure. The final dried gas mixture is subjected to flow control by a sample flow meter 13 and then enters an analyzer 17 for analysis.
Through the extraction, treatment and analysis of the processes, if the analyzer detects that toxic and harmful gas components such as CO exist in the mixed gas, even if the amount is PPm level, the toxic and harmful gas components are dissolved in the circulating water, and then the problem of leakage of the cooling tower device can be inferred.
The overflow port and the exhaust port structure of the online gas stripping tank ensure that the liquid level of the water seal section is constant, ensure that the gas pressure of the sample at the outlet of the online gas stripping tank is constant, and provide sufficient sample pressure and flow for an analysis instrument. In the online gas stripping tank, the fluctuation of the water seal liquid level height in the rising process of bubbles is very small, and the pressure of the extracted sample gas is not influenced by the pressure of a circulating water inlet and the fluctuation of flow. In addition, due to the adoption of a two-stage dewatering and drying process of the air cooler and the coalescer, the drying treatment is sufficient, and the sample is ensured to be suitable for an analyzer to analyze. In addition, the U-shaped structure is arranged at the tail end of the discharge of the gas-water mixture, so that the gas and the liquid can be simply and skillfully shunted, and the effect is excellent.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
