Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to a spray dust reduction effect testing system. Background Art

[0002] In the industrial field, especially in dust-intensive environments such as mines, construction sites and cement plants, dust pollution not only has a serious impact on the environment, but also poses a threat to workers' health. Spray dust suppression technology is widely used in these scenarios as an effective means of dust control. It sprays water mist to combine dust in the air with water droplets, thereby settling and reducing dust concentration. However, the effect of spray dust suppression is affected by many factors, including the water pressure, flow rate, atomization degree of the spray, and air flow in the spray area.

[0003] In the prior art, the design and optimization of spray dust suppression equipment usually rely on the operator's experience and intuitive judgment, and lack precise testing and analysis methods. This means that the effect of spray dust suppression often cannot be scientifically and objectively evaluated, and the efficiency of the equipment and the dust control effect are difficult to maximize. In addition, since spray dust suppression is usually carried out in dust-generating areas, such as mining machinery operation areas, these areas are often harsh and difficult for personnel and equipment to access, which increases the difficulty and inaccuracy of data collection.

[0004] At present, although there are some test platforms and methods for evaluating the effect of spray dust reduction, they often have the following problems: 1. Accuracy of data collection: Data collection methods that rely on manual operation and subjective judgment are easily affected by operator errors or deviations, resulting in reduced reliability of test data. 2. Monitoring of spray parameters: The lack of real-time monitoring and recording capabilities of spray parameters such as water pressure and flow rate cannot provide detailed data support for the improvement and optimization of spray dust reduction technology. 3. Multi-point monitoring capabilities: Existing test platforms can usually only monitor at fixed locations, and cannot detect dust concentration in larger spaces or multiple areas at the same time, limiting their application in complex working environments.

[0005] In order to solve the above problems and improve the scientificity and effectiveness of spray dust suppression technology, it is necessary to design a test platform and method that can automatically and accurately test and analyze the spray dust suppression effect to meet the higher requirements of dust control in the industrial field.

The coordinated use of the slide groove 71 and the slide rail 72 enables the sampling head 6 to move flexibly within a larger range, which can not only meet the monitoring needs of different heights, but also perform a large-scale scan in the horizontal direction, thereby ensuring a comprehensive evaluation of the spray dust reduction effect, and has a significant implementation effect on the dust reduction effect monitoring of the construction industry and open-pit mines.

[0036] like Figure 7 As shown, specifically, the automatic spray parameter collector 17 also includes a control module 171, a spray parameter controller 172, a solenoid valve 173, an electromagnetic flowmeter 174 and a water pressure sensor 175.

The horizontal extension design of the connecting water pipe 181 enables the atomizing nozzle 182 to cover a wider area, and through the evenly distributed atomized water droplets, the dust concentration in the air is effectively reduced, and the air quality of urban roads and large warehouses is improved, which plays an important role in improving the quality of life of urban residents and protecting the health of workers in warehouses.

[0039] Specifically, there are multiple atomizing nozzles 182, and the multiple atomizing nozzles 182 are spaced apart along the extension direction of the connecting water pipe 181. This design can achieve a wider coverage area and a more uniform spray effect through the coordinated work of multiple nozzles, and is suitable for occasions that require rapid and large-area dust reduction, such as air cleaning after forest fires, dust control in large-scale construction, etc., effectively improving air quality and protecting the environment and human health. The setting of multiple atomizing nozzles 182 not only increases the coverage of the spray, but also increases the density of the spray, which has a significant implementation effect on air cleaning after forest fires and dust control in large-scale construction, can quickly reduce the dust content in the air, protect the environment and human health, and can play an important role, especially in emergency rescue and construction sites.

[0040] Specifically, the atomizing spray mechanism also includes a fixing clamp 183, which is installed on the test platform body 1 and connected to the water supply pipe 18.

It can play an important role in various environments that require stable spraying, such as agricultural irrigation, landscape fountains, etc., and ensure the uniformity and effect of the spraying. The spaced distribution of the fixing clamps 183 can effectively support the water supply pipe 18, and can keep the water supply pipe 18 stable even during a long spraying process. This is the key to ensuring the spraying effect and system stability for occasions such as agricultural irrigation and landscape fountains that require continuous and stable spraying.
