Background technology
According to Ministry of Public Health's statistics, at present, the pneumoconiosis that China causes because of coal dust has exceeded more than 50 ten thousand people, accounts for greatly the more than 50% of whole world Pneumoconiosis Patients sum.And, in state-owned key enterprise, there is the newly-increased Pneumoconiosis Patients that exceedes 10,000 in annual China, every year on average, because of Death from Pneumoconiosis people more than 2500.Coal dust also can set off an explosion and the problem such as environmental pollution, and according to statistics, from founding of New so far, 106 of the explosion accidents causing because of coal dust, cause the injures and deaths of people more than 4613 altogether.The economic loss that the diffusion of coal dust causes can not be ignored, according to investigations, coal is in harbour handling transportation, play dust quantity and account for 0.1% of whole coal freight volume, the loss amount of coal accounts for 0.02% of whole coal freight volume, calculates by 100,000,000 tons of coals of the annual transfer in PORT OF TIANJIN, the annual dust quantity that rises reaches 100,000 tons of coal dusts, lose nearly 20,000 tons of coals, direct economic loss is more than 1,300 ten thousand yuan, and the caused environmental pollution of these coal dusts and stealthy economic loss that workers ' health is caused will be larger.
The potential safety hazard that coal dust causes and occupational health problem, become China and mined, used one of key technical problem of being badly in need of in the industries such as coal, transfer coal solution.Therefore, the foam colloidal sol new technology of control coal dust has been proposed, this technology utilizes foam as carrier, and bubble film is carried out to colloidization, by reinforced foam liquid film viscosity, thereby reach adsorption and sedimentation to airborne coal dust, stick to dump surface, control dump airborne dust and sealing isolation airborne dust region, control the object of coal dust loss.By the fundamental research to this technology, for this technology is from now on applied to on-the-spotly to ensureing workman's job safety and physically and mentally healthy and control environment and pollute etc., there is very major and immediate significance.
For testing out the adsorption and sedimentation of foam colloidal sol to airborne coal dust, quantitatively draw out foam colloidal sol to the adsorbance of dust relation curve over time, be necessary to develop a kind of for testing the experimental provision of foam colloidal sol absorption dust.
Summary of the invention
The present invention seeks to solve foam colloidal sol to the adsorbance of the dust mensuration problem of quantitative changing value in time, provide a kind of for testing the experimental provision of foam colloidal sol absorption dust.
