Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a monitoring device for organic matter content in industrial waste gas. Background Art

[0002] Industrial organic waste gas often has a special odor. Its main pollutants include aromatic hydrocarbons, aldehydes, ketones, halogenated hydrocarbons, alcohols, etc., all of which are toxic and harmful compounds. Some organic waste gases also have certain carcinogenic effects.

[0003] Monitoring devices are equipment used to measure and monitor the concentration and content of organic matter (such as volatile organic compounds (VOCs)) in industrial waste gas. They are often used to monitor waste gas emitted during industrial production processes to ensure that emissions comply with environmental regulations and protect the environment and human health.

[0004] According to patent publication number CN214635133U, a monitoring device for the organic content of industrial waste gas includes a purification box with support legs welded to the four corners of the bottom, a monitoring box welded to the top outer wall of the purification box, and one side of the monitoring box is connected to the exhaust pipe through a pipe sealing connector, and the other side of the monitoring box is connected to a U-shaped pipe through a sealing ring, and the top of the U-shaped pipe is connected to a vertical pipe. When the organic content detector detects that the organic content in the waste gas exceeds the standard, the first one-way valve on the vertical pipe is closed and the second one-way valve on the U-shaped pipe is opened. Under the action of the air pump, the waste gas quickly enters the purification box. After being cleaned by the atomizing nozzle, particulate matter in the waste gas can be removed. The ultraviolet sterilization lamp has a sterilizing effect. Finally, after being filtered by the activated carbon filter, toxic substances in the waste gas can be absorbed and removed. In this way, the industrial waste gas can be quickly purified and treated, thereby protecting the environment.

[0005] The above introduces the organic matter in industrial waste gas and the monitoring device. The waste gas is usually sent directly into the monitoring device, and the organic matter content in the waste gas is monitored online using infrared. However, the moisture in the waste gas will absorb infrared light. Therefore, when the waste gas is directly sent into the monitoring device for monitoring, it is easy to cause inaccurate monitoring results. Utility Model Content

[0006] The purpose of the utility model is to solve the technical problem in the prior art that the exhaust gas contains moisture, which leads to inaccurate monitoring results during infrared monitoring, and to propose a monitoring device for the organic matter content of industrial exhaust gas.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a monitoring device for the organic matter content of industrial waste gas, comprising a monitor, a control console is provided on the front of the monitor, a heating base plate is fixed on the bottom of the monitor, an exhaust port is provided on the top of the monitor, a dehydration chamber is provided inside the monitor, and stepped layers and baffles are respectively provided in the dehydration chamber. An intersection is passed through one side of the group of baffles, and two adjacent intersections are distributed up and down. A stepped chamber is provided between the two stepped layers, an ascending channel is provided inside the monitor, and an infrared detector and an infrared light source are respectively connected to the two sides of the interior of the monitor.

[0008] It can be seen that in the above technical solution, the exhaust gas can directly enter the monitor to detect the organic matter content in the exhaust gas. There is no need to worry about the moisture in the exhaust gas affecting the accuracy of infrared spectrum detection. In addition, the baffle plate and the stepped layer greatly extend the dehydration time of the exhaust gas and improve the dehydration efficiency, thereby effectively improving the accuracy of exhaust gas detection.

[0009] Preferably, the stepped layer is stepped, and is divided into an upper layer and a lower layer.

[0010] It can be seen that in the above technical solution, the stepped layer is in the shape of a step, and there is a stepped cavity between the two layers. After the exhaust gas passes through the baffle plate and enters the stepped cavity, the path of the exhaust gas can also be increased, and secondary dehydration can be performed.

[0011] Preferably, both ends of the baffle plate are fixed to the heating bottom plate and the bottom surface of the lower stepped layer respectively, and the baffle plate is perpendicular to the top surface of the heating bottom plate.

[0012] It can be seen that in the above technical solution, the two ends of the partition plate are fixed because the partition plate needs to be installed vertically, which increases the stability of the partition plate.

[0013] Preferably, a closing plate is fixed inside the monitor, and the closing plate is located on the top surface of the upper stepped layer, and the infrared detector and the infrared light source are flush with each other.

[0014] It can be seen that in the above technical solution, the exhaust gas passing through the stepped cavity can be directly subjected to infrared spectrum detection, so that all the exhaust gas needs to pass between the infrared light source and the infrared detector to complete the online monitoring of all the exhaust gas.

[0015] Preferably, a circulation pipe is connected to the interface on the back of the monitor, and the other end of the circulation pipe is located between two stepped layers.

[0016] It can be seen that in the above technical solution, the circulation pipe can transfer the exhaust gas after detection for a second time for re-detection, and can perform a second detection when the detection result is uncertain.

[0017] Preferably, the air inlet of the monitor is located in the dehydration chamber, and the air inlet of the monitor is located at the bottom of the lower stepped layer.

[0018] It can be seen that in the above technical solution, the exhaust gas inlet is located near the bottom of the lower stepped layer and on the left side of the monitor.

[0019] Beneficial effects

[0020] In the utility model, when the exhaust gas directly enters the monitor, electric heating can be used to quickly dehydrate the moisture in the exhaust gas, avoiding the problem of inaccurate monitoring results when the exhaust gas directly enters the monitor and is monitored by infrared, reducing interference factors during monitoring, improving the accuracy of monitoring, and making the information of infrared spectrum monitoring of the organic matter content in the exhaust gas more accurate. At the same time, baffles and stepped layers are added in the monitor, so that the exhaust gas passes slowly after entering, which greatly improves the quality of the exhaust gas dehydration treatment and repeatedly utilizes the space inside the monitor.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0028] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

[0030] Reference Figure 1-4 A monitoring device for the organic content of industrial waste gas includes a monitor 1. A control console 12 is provided on the front of the monitor 1. A heating base plate 5 is fixed to the bottom of the monitor 1. An exhaust port 14 is provided on the top of the monitor 1. A dehydration chamber 4 is provided inside the monitor 1. The organic content in the industrial waste gas needs to be monitored before it is discharged. If the organic content exceeds the standard, it will have an impact on the environment. The monitor 1 serves as the shell of the monitoring device for the organic content in industrial waste gas. The monitor 1 contains a dehydration chamber 4 inside. The waste gas can be dehydrated when it passes through. Since the waste gas is easily affected by the water in the waste gas when it is monitored by the red spectrum, The influence of the exhaust gas will lead to inaccurate monitoring results. The moisture in the exhaust gas will absorb infrared light and interfere with the detection of organic matter. Dehydration treatment is required, but the dehydration process may be complicated and affect the measurement results. Therefore, dehydration treatment is required before exhaust gas monitoring to improve the accuracy of monitoring. It is necessary to explain that infrared spectroscopy monitoring is when the exhaust gas passes through the detection cavity, the light emitted by the light source passes through the exhaust gas, and the infrared light of a specific wavelength is absorbed by the organic matter in the exhaust gas. The detector measures the attenuation of the infrared light intensity passing through the exhaust gas. According to the Beer-Lambert law, the absorbed light intensity is proportional to the organic matter concentration, and the concentration of the organic matter is thus calculated.

[0031] An ascending channel 8 is provided inside the monitor 1, and a stepped layer 2 and a baffle plate 6 are respectively provided in the dehydration chamber 4. An intersection 7 is passed through one side of the baffle plate 6, and the two adjacent intersections 7 are distributed up and down. The two ends of the baffle plate 6 are respectively fixed to the heating bottom plate 5 and the bottom surface of the lower stepped layer 2, and the baffle plate 6 is perpendicular to the top surface of the heating bottom plate 5. The exhaust gas is sent from the side of the monitor 1 to the dehydration chamber 4 through a conveying pump. At this time, the heating bottom plate 5 at the bottom of the monitor 1 is used for electric heating to heat the space inside the dehydration chamber 4 and dehydrate the passing exhaust gas. The exhaust gas needs to pass through multiple baffle plates 6 before passing through the dehydration chamber 4. Since the intersections 7 on the adjacent baffle plates 6 are staggered up and down, the route profile of the exhaust gas when passing through is S-shaped, which greatly increases the dehydration time of the exhaust gas and improves the efficiency of the exhaust gas dehydration.

[0032] The step layer 2 is stepped, and the step layer 2 is divided into an upper layer and a lower layer. A step cavity 3 is provided between the two step layers 2. The air inlet of the monitor 1 is located in the dehydration cavity 4, and the air inlet of the monitor 1 is located at the bottom of the lower step layer 2. The monitoring cavity also contains a step layer 2. The step layer 2 consists of two layers, the lower layer is fixedly connected to the top of the baffle plate 6, and the left side is fit and sealed with the left side of the inside of the monitor 1, and the upper layer is fit and sealed with the right side of the inside of the monitor 1. After the exhaust gas passes through multiple groups of baffle plates 6, it enters the step cavity 3 between the upper and lower step layers 2 from the ascending channel 8. The shape of the step layer 2 can also reduce the speed of the exhaust gas passing through, and the exhaust gas is removed again.

[0033] An infrared detector 9 and an infrared light source 10 are connected to the two sides of the interior of the monitor 1 respectively. Finally, the exhaust gas passes between the infrared detector 9 and the infrared light source 10. The concentration of organic matter in the exhaust gas is monitored by infrared means and in conjunction with an algorithm. The exhaust gas that meets the standards can be discharged directly. A circulation pipe 13 is connected to the interface on the back of the monitor 1, and the other end of the circulation pipe 13 is located between the two step layers 2. Secondary detection can also be performed under uncertain conditions. The pump on the back of the monitor 1 is used to re-pump the exhaust gas above the upper step layer 2 into the step cavity 3 for detection.

[0034] A closing plate 11 is fixed inside the monitor 1, and the closing plate 11 is located on the top surface of the upper stepped layer 2, and the infrared detector 9 and the infrared light source 10 are flush with each other. It is necessary to note that the infrared light source 10 and the infrared detector 9 have the same length, and the light source emits light through the exhaust gas and finally irradiates the detection surface of the infrared detector 9. At the same time, the closing plate 11 is located on the top surface of the upper stepped layer 2, which is used to seal the detection area.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature.
