Problems solved by technology
[0003] The estimation of the amount of dust generated in the port is the basis for the prevention and control of dust pollution in the port. source is difficult to estimate
And because the bucket-wheel stacker-reclaimer is in dynamic operation during reclaiming operation, the movement of dust particles in the atmosphere has great randomness, so conventional measurement or theoretical prediction methods are used to analyze the dynamic operation of the bucket-wheel stacker-reclaimer The amount of dust generated during the time has a large limitation

Embodiment
[0063] The embodiment of the present invention discloses a wind tunnel simulation test method for the amount of dust generated by a bucket-wheel stacker-reclaimer, which includes the following steps:
[0064] Step 1. Clean the dust inside the wind tunnel to avoid measurement interference;
[0065] Step 2. Weigh the test material before the test and pile it up in the wind tunnel, and record the weight of the material pile before the test as M1;
[0066] Step 3. Prepare the model device for the wind tunnel simulation test of the amount of dust generated by the bucket-wheel stacker-reclaimer, and weigh the model device for the wind tunnel simulation test of the amount of dust generated by the bucket-wheel stacker-reclaimer before the test. The net weight of the wind tunnel simulation test model device for the amount of dust generated by the bucket-wheel stacker-reclaimer is denoted as M2;
[0067] Step 4: Set up the wind tunnel simulation test model device for the amount of dust...

The invention discloses a bucket wheel type stacker-reclaimer dusting quantity wind tunnel simulation test model device and test method. According to the structure of the bucket wheel type stacker-reclaimer dusting quantity wind tunnel simulation test model device, a screw rod is in transmission connection with a screw rod support; one end of the screw rod is connected with the output shaft of a power device; the other end of the screw rod is connected with a bucket-wheel machine head model; the bucket-wheel machine head model is driven to rotate through the power device; and therefore, the authenticity and accuracy of a wind tunnel simulation test can be ensured. The bucket wheel type stacker-reclaimer dusting quantity wind tunnel simulation test model device and a test material pile areweighed separately before and after the test, and therefore, the dusting quantity of a bucket wheel type stacker-reclaimer during working can be accurately calculated; and a method for effectively evaluating dusting quantities is provided for environmental protection for bulk cargo ports.
Description
technical field [0001] The invention relates to the technical field of atmospheric dust pollution prevention and environmental protection, and more specifically relates to a wind tunnel simulation test method for the amount of dust generated by a bucket-wheel stacker-reclaimer. Background technique [0002] At present, my country's atmospheric environment is not optimistic. The Yearbook of my country's Air Environmental Pollution in 2000 shows that the most important pollutant in air pollution is particle pollution. However, particulate matter pollution has complex components and many sources, coupled with the continuous deterioration of the ecological environment in recent years, making particulate matter pollution the primary factor leading to air pollution in most cities in my country. For example, my country is in the peak period of growth of coal and ore throughput in coastal ports, and the problems of dust emission and diffusion pollution caused by this are very seriou...
