Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment test device. Background Technology

[0002] Industrial waste gas treatment is a crucial issue in environmental protection. For industries such as aero-engine testing, automotive manufacturing, power generation, chemical processing, and metallurgy, exhaust tower emissions contain pollutants such as nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM). Waste gas treatment equipment is required to treat these pollutants until they meet emission standards before discharge. Current technologies often rely on experience and theoretical calculations to select suitable agents or dosages for treatment equipment. However, experience and theoretical calculations often fail to fully account for various influencing factors in actual use, resulting in unsatisfactory treatment effects after the equipment is put into operation, necessitating multiple adjustments to meet treatment requirements. Utility Model Content

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0024] One specific embodiment of this utility model discloses a waste gas treatment test device, used to select suitable types or dosages of treatment agents for pollutants in the waste gas being treated; this embodiment is illustrated using the treatment of waste gas containing volatile organic compounds (VOCs) as an example. Figure 1As shown, the system includes a sequentially connected air intake pipe 1, an air intake fan 2, a monitoring pipeline 4, a test unit 5, and an exhaust pipe 6. The air intake pipe 1 is used to connect to an exhaust tower. The air intake fan 2 is used to introduce the waste gas from the exhaust tower into the test unit 5 in a proportional manner. The monitoring pipeline 4 is used to install a monitoring instrument to monitor the temperature, flow rate, and concentration of the waste gas before treatment. The test unit 5 includes multiple test pipelines connected in parallel. Different types of treatment agents or different amounts of the same treatment agent are filled in different test pipelines to treat the waste gas. Compared with the prior art, this embodiment treats the waste gas by filling different types of treatment agents or different amounts of the same type of treatment agent in multiple test pipelines. By comparing the waste gas treatment data of different test pipelines, it is possible to quickly select the appropriate type or amount of treatment agent for the waste gas to be treated, and then fill it into the waste gas treatment equipment in a proportional manner. The treatment requirements can be met without multiple adjustments, which can effectively save time and costs.

[0025] Preferably, such as Figure 2 As shown, the monitoring pipeline 4 is provided with a first monitoring hole 41. The first monitoring hole 41 is used to install a monitoring instrument to detect the exhaust gas before treatment as needed. For example, in this embodiment, a thermometer, a flow meter and a VOCs concentration meter are installed to measure the temperature, flow rate and concentration of the exhaust gas before treatment, and the test personnel make records.

[0026] Preferably, such as Figure 2 As shown, the multiple test pipelines have the same structure. Each test pipeline includes a control valve 51, a second monitoring port 52, a third monitoring port 53, and a packing chamber 54. The control valve 51 is located upstream of the packing chamber 54 and is used to regulate the flow rate of the exhaust gas entering the packing chamber 54. The second monitoring port 52 is located between the packing chamber 54 and the control valve 51. The second monitoring port 52 is used to install a monitoring instrument to detect the untreated exhaust gas in the test pipeline as needed. For example, in this embodiment, a thermometer, flow meter, and VOCs concentration meter are installed to measure the temperature, flow rate, and concentration of the untreated exhaust gas, and the results are recorded by the test personnel. The packing chamber 54 is used to fill the treatment agent to treat the pollutants in the exhaust gas. The third monitoring port 53 is located downstream of the packing chamber 54. The third monitoring port 53 is used to install a monitoring instrument to detect the treated exhaust gas in the test pipeline as needed. For example, in this embodiment, a thermometer, flow meter, and VOCs concentration meter are installed to measure the temperature, flow rate, and concentration of the treated exhaust gas, and the results are recorded by the test personnel.

[0027] In practical use, different types of treatment agents or different dosages of the same type of treatment agent are filled into the packing compartments 54 of different test pipelines. According to the test requirements, monitoring instruments are installed in the second monitoring hole 52 and the third monitoring hole 53. The exhaust pipe 1 is connected to the exhaust tower, and the exhaust gas in the exhaust tower is introduced into the tower in proportion by the exhaust fan 2. The working conditions of the exhaust gas flowing into each test pipeline are adjusted by adjusting the control valve 51 in each test pipeline to keep the working conditions of the exhaust gas flowing into each test pipeline the same. Then, the test data before and after the exhaust gas treatment are recorded. By comparing the exhaust gas treatment data of different test pipelines, it is possible to quickly select the appropriate type or dosage of treatment agent for the exhaust gas to be treated, and then fill it into the exhaust gas treatment equipment in proportion. The treatment requirements can be met without multiple adjustments, which can effectively save time and costs.

[0028] Preferably, the packing compartment 54 is provided with an observation window 55, which is hinged to the packing compartment 54 and can be opened, so as to facilitate the filling of the treatment agent into the packing compartment 54 and to observe the changes of the treatment agent in the packing compartment 54 at any time through the observation window 55.

[0029] Preferably, the waste gas treatment test device further includes a heater 3, which is located upstream of the monitoring pipeline 4. The heater 3 is used to adjust the temperature of the waste gas entering the test unit 5 so that the waste gas temperature is maintained within the temperature range required by the treatment agent, thereby ensuring the stability of the test and improving the accuracy of the test.

[0030] Preferably, the heater 3 uses equipment from the prior art.

[0031] Preferably, the waste gas treatment test device further includes a movable platform 7, which includes a mounting plate 71 and rollers 72. The exhaust pipe 1, exhaust fan 2, heater 3, monitoring pipeline 4, test unit 5 and exhaust pipe 6 are all mounted on the mounting plate 71. The rollers 72 facilitate the movement of the waste gas treatment test device, thereby improving the flexibility of the waste gas treatment test device.
