Detection method for concentration of silica dust in workplace

Abstract

The invention discloses a detection method for the concentration of silica dust in a workplace. According to the invention, dust in the air is sampled and collected through a sampling device; collected dust is weighed and measured; a corresponding chemical reaction is performed so as to obtain the corresponding mass of silicon dioxide; then whether the dust in the air is silica dust or not is determined; and the concentration of the silica dust in the workplace is judged. Compared with the prior art, the detection method provided by the invention has the following advantages: the detection accuracy of the concentration of the silica dust is greatly improved; meanwhile, the content of the silicon dioxide in the silica dust is detected, so the current harm extent of the silica dust is more effectively judged; and the safety of a worker is protected to a greater extent.

Description

technical field [0001] The invention relates to the field of silicon dust detection, in particular to a method for detecting the concentration of silicon dust in a workplace. Background technique [0002] In the ferrous metal mining industry, non-metallic mining industry, construction industry and other similar industries, a large amount of dust is generated due to the need to drill, crush, grind and cut ore or sand in the workplace of these industries. Diffuse in the air, and due to the free silica in the dust generated by the ore, when the content of silica in the dust reaches 10% or more of the dust content, the dust in the air at this time is called "" Silicon Dust". "Silica dust" containing silicon dioxide will cause direct damage to the lung tissue. Once the long-term workers in the workplace inhale too much silicon dust, silicon dioxide will accumulate in the lungs for a long time, causing more lung tissue. Repeated damage causes extensive nodular fibrosis in the lu...

Problems solved by technology

The "silica dust" containing silica will cause direct damage to the lung tissue. Once the long-term workers in the workplace inhale too much silica dust, the lungs will accumulate silica for a long time, resulting in hypertrophy of the lung tissue. Repeated damage causes extensive nodular fibrosis in the lungs, which seriously affects lung function and causes "silicosis".
