Description

Technical Field

[0001] The invention relates to the technical field of water dissolution, and more particularly to a dosing device for preventing dust hazards. Background Art

[0002] In the field of water treatment for environmental protection projects, the dosing process plays a vital role in water purification. However, for a long time, there has been a serious problem in the dosing process that needs to be solved urgently.

[0003] In actual engineering operations, workers often need to add activated carbon powder, caustic soda flakes, lime and other materials. These materials will generate a lot of dust when added. From the perspective of the impact on workers' health, dust is easily inhaled into the respiratory tract by workers. Long-term exposure to such an environment will cause a series of respiratory diseases, such as pneumoconiosis, which seriously damages the health of workers and causes many workers to resist the work of adding chemicals and are unwilling to engage in this task.

[0004] From the perspective of environmental protection, the dust generated during the dosing process spreads into the surrounding air, causing dust pollution in the surrounding environment, damaging the surrounding air quality, and having an adverse impact on the ecological environment. Although environmental protection projects have continued to develop and progress in overall water quality treatment, they have not been effectively improved in the specific link of dosing dust prevention.

[0005] After extensive market research, we found that most of the existing dosing devices on the market do not provide effective solutions to the dust hazard problem.
