[0001] The utility model belongs to the technical field of waste gas monitoring, and in particular relates to an online monitoring device for organic waste gas VOC in the synthetic resin industry. Background Art

[0002] Synthetic resins are made from simple organic substances through chemical reactions. Therefore, VOCs (volatile organic compounds) are produced in the process of making synthetic resins. VOCs have a huge impact on human health. When VOCs reach a certain concentration, people will feel headaches, nausea, vomiting, fatigue, etc. in a short period of time. In severe cases, convulsions and coma may occur. It will also damage the liver, kidneys, brain and nervous system, causing serious consequences such as memory loss. Therefore, VOC monitoring is very necessary.

[0003] In the existing process of monitoring VOC, the position of the detection device is relatively fixed, and the different densities of the gas in the VOC lead to different gas concentrations at different heights, which in turn leads to inaccurate monitoring data obtained by the detection device during the monitoring process at a fixed position.

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Embodiment 1, according to Figure 1-Figure 3 Provide further explanation.

[0021] The utility model provides an online monitoring device for VOC of organic waste gas in synthetic resin industry, comprising a base plate 1, wherein support rods 2 are symmetrically fixedly connected to the upper surface of the base plate 1, a transmission component is connected between the two support rods 2, an adjustment component is connected to the transmission component, a detection box 3 is installed above the adjustment component, the transmission component is used to adjust the height of the detection box 3, and the adjustment component is used to adjust the direction of the detection box 3.

[0022] The transmission assembly includes a motor 4 fixedly connected to the upper surface of the base plate 1, a screw rod 5 fixedly connected to the output end of the motor 4, a fixing rod 6 symmetrical to the screw rod 5 fixedly connected to the upper surface of the base plate 1, and a lifting plate 7 penetrating the screw rod 5 and the fixing rod 6 is provided above the base plate 1, the lifting plate 7 is threadedly connected to the screw rod 5 and slidably connected to the fixing rod 6.

[0023] The adjustment assembly includes a concave platform 8 fixedly connected to the upper surface of the lifting plate 7, the inner wall of the concave platform 8 is circular, and a convex platform 9 is rotatably connected to the middle of the concave platform 8.

[0024] An air inlet 10 and an air outlet 11 are provided on the surface of the detection box 3 , and an oil-gas separator 12 , a water-vapor separator 13 , an air pump 14 , a flow meter 15 and a VOC detector 16 are fixedly installed inside the detection box 3 .

[0025] The two sides of the boss 9 are rotatably connected to one end of a limiting rod 17 , and limiting grooves 18 are spaced apart on the inner wall of the recess 8 .

[0026] When it is necessary to monitor the gas in the environment, since the limiting grooves 18 are arranged on the inside of the groove, and the angles are engraved at the positions corresponding to the limiting grooves 18, the inner wall of the concave platform 8 is circular, and the inner wall of the entire concave platform 8 is 360 degrees, and the operator can first align the limiting rod 17 connected to the boss 9 with the zero degree on the concave platform 8, and then insert the end of the limiting rod 17 away from the boss 9 into the limiting groove 18, thereby fixing the boss 9 to prevent the boss 9 from rotating and driving the monitoring box to rotate. Then the operator starts the motor 4 fixedly installed on the upper surface of the base plate 1, and the motor 4 drives the screw rod 5 fixedly connected to the output end of the motor 4 to rotate, and the rotation of the screw rod 5 drives the lifting plate 7 that penetrates the screw rod 5 and the fixed rod 6 to rise a certain distance After separation, the motor 4 stops moving. At this time, the air inlet 10, oil-gas separator 12, water-gas separator, air pump 14, flow meter 15, VOC detector 16, and air outlet 11 on the detection box 3 are connected in sequence through pipelines, and then the air pump 14 fixedly installed inside the detection box 3 extracts external gas. The external gas passes through the oil-gas separator 12 and the water-gas separator in sequence to remove water and oil in the gas, and then enters the flow meter 15 and VOC detector 16 through the air pump 14. The flow meter 15 monitors the flow of the gas, and the VOC detector 16 monitors the gas content of each part. The output monitored by the VOC detector 16 is transmitted to the external terminal through the antenna for the operator to view, and then the gas is finally discharged from the air outlet 11. When the gas monitoring at this height is completed, the operator turns on the motor 4 again, and the motor 4 drives the lifting plate 7 to rise again, and then monitors the gas at the previous height, so that the operator can obtain the data of the gas content at different heights in the same direction. When the gas monitoring in the zero degree direction is completed, the operator rotates the boss 9 again to align the limit rod 17 with the direction of the scale of ninety to perform gas monitoring at different heights. Through the above process, the gas in different directions and at different heights can be monitored to further improve the monitoring accuracy.

[0027] As a specific implementation of the present utility model, first rollers 19 are rotatably connected to both sides of the lifting plate 7 , and sliding grooves 21 matching with the first rollers 19 are provided on opposite surfaces of the two support rods 2 .

[0028] First rollers 19 are rotatably connected on both sides of the lifting plate 7, and sliding grooves 21 matching with the first rollers 19 are provided on the opposite surfaces of the two support rods 2. This structure can improve the stability of the lifting plate 7, and the support rods 2 support the lifting plate 7, while reducing the friction between the lifting plate 7 and the support rods 2.

[0029] As a specific implementation of the present utility model, a second roller 20 is rotatably connected to the bottom of the base plate 1 .

[0030] The second roller 20 is connected by rotating the bottom of the sub-base plate 1, so that the operator can push the device to the corresponding position to reduce the difficulty of carrying the device. The second roller 20 can be installed with a part for braking the second roller 20. This is the prior art and will not be described in detail.

[0031] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail.
