Description

Technical Field

[0001] This utility model relates to the field of volatile organic compound (VOC) detection technology, and in particular to a VOC monitor for use in the exhaust emissions of stationary pollution sources. Background Technology

[0002] Volatile organic compounds (VOCs) are serious air pollutants and precursors to PM2.5 in the atmosphere. Major sources of VOCs include the petrochemical industry, coal processing and conversion, and industries that use VOCs as raw materials, such as paints, inks, adhesives, and pesticides. To protect the ecological environment and achieve sustainable national development, it is essential to eliminate VOCs as an air pollutant. To better manage VOCs, VOC monitoring instruments are typically installed at the emission points of stationary pollution sources, significantly enhancing the monitoring of pollutants.

[0003] Existing detection devices have certain drawbacks. They are bulky and inconvenient to carry and use. Furthermore, they cannot quickly prepare samples of exhaust gas, which affects the efficiency of detection. Therefore, there is an urgent need for a volatile organic compound (VOC) monitor for exhaust gas emissions from stationary pollution sources to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a volatile organic compound (VOC) monitoring instrument for emissions from stationary pollution sources. This invention is achieved through the following technical solution.

[0005] A volatile organic compound (VOC) monitor for emissions from stationary pollution sources includes a housing, inside which a vacuum pump and a battery are housed. Control buttons on the outer surface of the housing are used to control the operation of the vacuum pump. The monitor also includes:

[0006] An exhaust gas absorption plate is fixedly connected to the outer shell, and the interior of the exhaust gas absorption plate is filled with organic absorbent liquid for collecting exhaust gas.

[0007] A metal corrugated pipe is fixedly connected to the exhaust gas absorption plate. A plastic tube is fixedly connected to one end of the metal corrugated pipe. A flexible tube is embedded in the plastic tube. A gravity ball is fixedly connected to one end of the flexible tube.

[0008] An air intake hood is fixedly connected to a metal bellows, and a filter cover is fixedly connected to the air intake hood, with a filter screen provided on the filter cover.

[0009] Furthermore, a charging port is provided on the outer surface of the housing, and the air pump, battery, control button and charging port are all electrically connected by wires.

[0010] Furthermore, the suction end of the air pump extends outside the outer casing and communicates with the exhaust gas absorption plate, and the exhaust end of the air pump extends outside the outer casing.

[0011] Furthermore, the exhaust gas absorption plate is made of transparent plastic material, and the transparent plastic material is polystyrene.

[0012] Furthermore, the maximum capacity of the organic absorbent liquid accounts for two-fifths of the total volume of the waste gas absorption pan.

[0013] Furthermore, the organic absorbent is any one of polyethylene ether, cold methanol, and diethanolamine.

[0014] The beneficial effects of this utility model are that, during the operation of this device, the device is first picked up by hand, and the suction hood connected to the outer shell is extended into the vicinity of the pollution source. Then, the air pump is turned on to draw in air. The absorbed waste gas is first filtered through the suction hood, and the filtered waste gas is input into the flexible tube connected to the plastic tube through the metal corrugated pipe. Since the gravity ball connected to the flexible tube always sinks into the organic absorbent liquid due to its own gravity, the organic absorbent liquid can fully absorb the pollution source gas. After the organic absorbent liquid absorbs the waste gas, it can directly make samples, which facilitates the detection of pollution source waste gas. The structure is simple, easy to disassemble and assemble, and easy to carry and use. Attached Figure Description

[0026] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0027] Example:

[0028] A volatile organic compound (VOC) monitor for emissions from stationary pollution sources includes a housing 1, inside which a vacuum pump 11 and a battery 12 are housed. A control button 13 on the outer surface of the housing 1 controls the operation of the vacuum pump 11. The monitor also includes:

[0029] Waste gas absorption plate 2 is fixedly connected to the outer shell 1, and the interior of the waste gas absorption plate 2 is filled with organic absorbent liquid for collecting waste gas;

[0030] A metal corrugated pipe 3 is fixedly connected to the exhaust gas absorption plate 2. A plastic tube 31 is fixedly connected to one end of the metal corrugated pipe 3. A flexible tube 32 is embedded in the plastic tube 31. A gravity ball 33 is fixedly connected to one end of the flexible tube 32. The metal corrugated pipe 3 has a dyeing function and is easy to adjust.

[0031] The suction hood 4 is fixedly connected to the metal corrugated pipe 3. A filter cover 41 is fixedly connected to the suction hood 4, and a filter screen 42 is provided on the filter cover 41.

[0032] Specifically, the outer surface of the housing 1 is provided with a charging port 14. The air pump 11, the battery 12, the control button 13 and the charging port 14 are all electrically connected by wires, so that the control button 13 can drive the gas to circulate.

[0033] Specifically, the suction end of the air pump 11 extends out of the outer shell 1 and communicates with the waste gas absorption plate 2, and the exhaust end of the air pump 11 extends out of the outer shell 1, which enables the air pump 11 to drive gas circulation.

[0034] Specifically, the waste gas absorption plate 2 is made of transparent plastic material, and the transparent plastic material is polystyrene, which allows observation of the absorption effect of the absorbent liquid inside the metal corrugated pipe 3.

[0035] Specifically, the maximum capacity of the organic absorbent liquid accounts for two-fifths of the total volume of the waste gas absorption plate 2, to prevent waste gas from being discharged from the inlet and outlet of the waste gas absorption plate 2.

[0036] Specifically, the organic absorbent liquid is any one of polyethylene ether, cold methanol, and diethanolamine, which can better absorb waste gas.

[0037] The working principle of this utility model:

[0038] When using the device, first pick it up by holding the outer casing 1, and extend the suction hood 4 connected to the outer casing 1 into the vicinity of the pollution source. Then, turn on the air pump 11 to suck in the air. The absorbed waste gas is first filtered through the suction hood 4. After filtration, the waste gas is input into the flexible tube 32 connected to the plastic tube 31 through the metal corrugated tube 3. Since the gravity ball 33 connected to the flexible tube 32 always sinks into the organic absorption liquid due to its own gravity, the organic absorption liquid can fully absorb the pollution source gas. After the organic absorption liquid absorbs the waste gas, it can directly make samples, which facilitates the detection of pollution source waste gas. The structure is simple, easy to disassemble and assemble, and easy to carry and use.
