Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment monitoring technology, specifically to an emission monitoring device for waste gas treatment. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially from chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries. The waste gas emitted has a strong odor, seriously pollutes the environment, and affects human health. After the waste gas is treated, gas monitoring equipment is usually used to monitor the various properties of the gas.

[0003] Emission monitoring devices for exhaust gas treatment typically include a sampling unit, a filtration unit, and a gas analysis and processing unit. The sampling unit usually consists of a sampling tube and a flange. One end of the sampling tube is connected to the exhaust pipe, and the other end is connected to the filtration unit. The sampling tube is used to collect a portion of the exhaust gas for monitoring.

[0004] Most existing sampling tubes are straight pipes. Since exhaust gas often contains water vapor, dust and particulate matter, water vapor is easily adsorbed on the inner wall of the sampling tube and the filter screen when the exhaust gas passes through the sampling tube and the filter unit. This makes the water vapor easily stick to the dust and particulate matter, which can easily clog the sampling tube and the filter screen, affecting the normal flow of exhaust gas and thus affecting gas monitoring. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an emission monitoring device for waste gas treatment. It solves the problem that with linear sampling tubes, since waste gas often contains water vapor, dust, and particulate matter, water vapor is easily adsorbed on the inner wall of the sampling tube and the filter screen when the waste gas passes through the sampling tube and filter unit. This water vapor easily adheres to dust and particulate matter, which can clog the sampling tube and filter screen, affecting the normal flow of waste gas and thus affecting gas monitoring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An emission monitoring device for waste gas treatment includes a sampling tube unit, a filter unit, and a gas delivery pipe. The sampling tube unit is connected to the filter unit, and the gas delivery pipe is located below the filter unit. The sampling tube unit includes:

[0007] Inclined tube, wherein the inclined tube is set at an angle, and the inclined tube is used to return liquid water generated by the condensation of water vapor in the waste gas;

[0008] An inverted U-shaped tube, wherein the inverted U-shaped tube is shaped like an inverted U, and one end of the inverted U-shaped tube is fixedly connected to one end of an inclined tube, the inverted U-shaped tube is used to slow down the flow rate of water vapor in the exhaust gas in order to accelerate the condensation rate of water vapor in the exhaust gas.

[0009] Preferably, the sampling tube unit further includes:

[0010] A connecting pipe, one end of which is fixedly connected to the other end of an inverted U-shaped pipe;

[0011] The flange is provided in multiple configurations, one of which is fixedly connected to the other end of the connecting pipe, and another flange is fixedly connected to the other end of the inclined pipe.

[0012] Preferably, the filtering unit includes:

[0013] A support plate, which is used to mount the sampling tube unit and the filter unit;

[0014] A sleeve, wherein the sleeve is disposed on a bearing plate;

[0015] A base, which is fixedly connected to the bottom of the sleeve;

[0016] A filter assembly is disposed inside and below the sleeve.

[0017] Preferably, the sleeve is fixedly connected to the gas pipeline.

[0018] Preferably, the base has a slot.

[0019] Preferably, the filtering component includes:

[0020] A filter screen cylinder is movably inserted into a sleeve and is connected to a connecting pipe. The filter screen cylinder is used to filter impurity particles in exhaust gas.

[0021] A fixing rod is fixedly connected to the bottom end of the filter screen cylinder;

[0022] A rotating block, which is fixedly connected to the end of a fixed rod.

[0023] Preferably, the end side of the filter cylinder is provided with a locking block, which is engaged in a locking groove.

[0024] Preferably, a gas analyzer is installed at the bottom of the gas pipeline.

[0025] This utility model discloses an emission monitoring device for waste gas treatment, which has the following beneficial effects:

[0026] The emission monitoring device for this waste gas treatment is equipped with a sampling tube unit, which consists of an inclined tube, an inverted U-shaped tube, and a connecting tube. The inclined tube is set at a certain angle to the side wall of the exhaust pipe, so that the water vapor condensed on the wall of the inclined tube flows downward under the action of gravity and flows back into the treatment device. The inverted U-shaped tube can slow down the flow rate of water vapor in the waste gas, thereby accelerating the condensation rate of water vapor in the waste gas. This allows the water vapor in the waste gas to condense quickly and flow back into the treatment unit, reducing the amount of water vapor entering the sampling tube and the filter cylinder. This reduces the adhesion of water vapor with dust and particulate matter in the sampling tube and the filter cylinder, lowers the risk of blockage, and facilitates the normal flow of waste gas, thus facilitating waste gas monitoring.
