Background
In the combustion process of the coal-fired unit boiler, if the boiler is in a local anoxic state, a large amount of H2S gas can be generated, and the H2S gas can cause high-temperature corrosion of the water-cooled wall. To reduce the high temperature corrosion caused by H2S gas, it is desirable to measure the H2S content of the water wall area. The existing measuring device and method are that holes are formed in a water-cooled wall, a metal pipe is connected into a hearth through the holes, the other end of the metal pipe is connected with an H2S tester, and the H2S content of flue gas in the area is measured. The metal pipe is directly perforated and connected into the hearth, and the metal pipe is in the high-temperature environment of the hearth for a long time, so that the metal pipe is easy to burn and block, and the service life is influenced. Meanwhile, after the flue gas is extracted, the flue gas does not pass through a drying device, and H2S gas is absorbed after moisture condensation, so that the accuracy of a detection result is affected.
Disclosure of Invention
The utility model aims to provide a portable water-cooled wall H2S gas monitoring device, and raw flue gas extracted from a hearth is cooled by ambient atmosphere and then returned to the hearth without changing the flue gas components of the hearth.
The above object is achieved by the following technical scheme:
the utility model provides a portable water-cooling wall H2S gas monitoring device, its constitution includes the sampling pole, returns smoke vent and smoking pipe, the sampling pole be cavity structure, and inserted the smoking pipe in the sampling pole, the smoking pipe pass through the inlet connection of first coupling hose and drying cabinet, the export of drying cabinet passes through second coupling hose and pump body access connection, the export of the pump body passes through third coupling hose and gas detector air inlet connection, the gas detector gas vent passes through the meeting smoke vent connection of fourth coupling hose and sampling pole, forms the closed loop.
The sampling rod is inserted into the hearth through a fire observation hole on the water-cooled wall of the hearth.
The portable water-cooled wall H2S gas monitoring device is characterized in that the front end and the tail part of the sampling rod are cylindrical cavity structures with different diameters.
The portable water-cooled wall H2S gas monitoring device is characterized in that the smoke extraction pipe is of a hollow pipe structure, and the circle centers of the smoke extraction pipe and the sampling rod are on the same horizontal plane.
The utility model has the beneficial effects that:
1. the independent sampling rod is used on site during detection, does not need to be fixed on a hearth water-cooled wall, and is convenient to use.
2. The flue gas returns to the hearth through the flue gas return port, so that the effect of cooling the sampling rod can be achieved, and the sampling rod is prevented from being burnt.
3. The flue gas with the cooling function is the raw flue gas extracted from the hearth, and returns to the hearth again, so that the flue gas components of the hearth cannot be changed, and the detection result cannot be influenced.
4. The portable smoke sampling rod provided by the utility model is provided with the smoke return port, and plays a role in cooling the sampling rod.
The sampling rod is inserted into the hearth through a fire observation hole on the water-cooled wall of the hearth. The flue gas is extracted from the hearth through the sampling rod, the flue gas passes through the annular cavity in the sampling rod and then passes through the drying box after passing through the smoke extraction port at the tail part of the sampling rod, the drying agent in the drying box dries the flue gas, the dried flue gas enters the gas detector through the pump body, and the flue gas returns to the hearth through the smoke return port of the sampling rod after flowing through the gas detector. The flue gas exchanges heat with the atmosphere with lower temperature through the whole flow, the temperature is reduced, and the temperature of the sampling rod can be effectively reduced by returning the flue gas to the hearth through the smoke return port, so that the sampling rod is prevented from being burnt.
