Abstract

The invention discloses an automatic visual multi-factor coupled dust removal experiment system. The system comprises a splicable transparent roadway box device, a parameterized variable-frequency mute ventilation device, an automatic circuit control device, a liquid concentration quantitative proportioning stirring device, a liquid power source distribution device, a gas power source distribution device, a nozzle space adjusting device, a demisting rectifying device, a high-voltage electrostatic generating device, a water magnetizing device, an intelligent dust generating device. a sensor detection device and a data acquisition device, wherein the splicable transparent roadway box body device is of a main body wind tunnel structure and is convenient to observe and adjust; and the data acquisition device and the sensor detection device are arranged on two sides of the roadway box body and are used for acquiring data and adjusting relevant parameters in the device in real time. According to the invention, comparative investigation of multi-factor coupling on the spray dust removal effect can be realized, obtained data are scientific and reliable, and the problem of relatively large error in the previous spray dust removal experiment process can be improved, so that reasonable guidance is provided for reasonably selecting spray dust removal modes.

Description

technical field [0001] The invention belongs to the technical field of exploring dust prevention and control methods, and in particular relates to an experimental device for studying the influence of various coupling factors in spray dust removal on the dust removal effect under multiple working conditions. Background technique [0002] By the end of 2020, my country had reported a total of 795,000 cases of occupational diseases, of which 873,000 were occupational pneumoconiosis, accounting for about 90% of the total number of reported occupational disease cases. The number of new cases of pneumoconiosis in coal mines accounted for more than 50% of pneumoconiosis. In 2019, the number of new cases of coal workers' pneumoconiosis accounted for as high as 83%. The adverse effects of coal mine dust on coal mine employees have far exceeded safety production accidents. It is of great significance to ensure the occupational safety and health of coal mine employees throughout their li...

Problems solved by technology

However, the spray dedusting technology involves a large number of different influencing factors. In the research, it is often necessary to consider the demisting effect achieved by the mutual coupling of different influencing factors, which makes the experimental process cumbersome and complicated.

However, the research and development of complete sets of technologies and equipment suitable for the prevention and control of dust in my country's coal mines, as well as the experimental equipment and the transformation of achievements are still somewhat blank.
