Description
Technical field
The present invention relates to dust-inhibitor technical field, particularly relate to a kind of multifunctional ecological high-efficiency dust suppressant and preparation technology's and methods for using them thereof.
Background technology
Along with the develop rapidly of China's economy; environmental pollution becomes more and more serious; wherein dust pollution is one of principal element causing environmental pollution; in the production storage locations such as port and pier, power plant, cement mill, coal yard and railway, transport by road process; usually can produce a large amount of dust; not only directly threaten production safety, also can produce environment and pollute greatly.
Since in January, 2013, the monitoring points such as north, Xizhimen, Beijing, South 3rd Ring Road, the Olympic Sports Center monitor PM2.5 real-time concentration and breach 900 micrograms/cubic meter, and traffic pollution monitoring point, north, Xizhimen is up to 993 micrograms/cubic meter.Chinese Academy of Sciences atmospheric physics institute researcher, doctoral advisor Wang Yue think to claim, PM2.5 every cubic metre exceeded 900 micrograms/cubic meter create in new peak since state-owned PM2.5 monitoring data.North China, Central China, northwest, Southeastern Coastal Cities PM2.5 also often cross 300 micrograms/every cubic metre, reach severe contamination; Until 2013 the end of the year different cities PM2.5 also brushing out new peak.
Dust pollution is atmosphere pollution mainly, the health of harm humans.The dust floated in an atmosphere contains many toxic ingredients, as chromium, manganese, cadmium, lead, mercury, arsenic etc.After human body sucks dust, be less than the particulate of 5 μm, very easily go deep into lung, cause toxic pneumonitis or silicosis, time serious, cause lung cancer.Within 2010, Beijing, Shanghai, Guangzhou, Xi'an cause early dead person's number to be 2349,2980,1715,726 people because PM2.5 pollutes respectively, amount to 7770 people, the ratio accounting for total toll then is respectively 1.9%, 1.6%, 2.2%, 1.5%, and financial loss is respectively 18.6,23.7,13.6,5.8 hundred million yuan.
Chinese Patent Application No. 201210195579.2 discloses a kind of dust-inhibitor for suppressing dust to suspend, and the composition of its dust-inhibitor comprises: 50 ~ 90 parts, water, polyvinyl alcohol 2 ~ 30 parts, polysaccharide 1 ~ 20 part, 0.5 ~ 5 part, tensio-active agent, Sodium Benzoate 0.1 ~ 3 part; But tensio-active agent is unstable in this dust-inhibitor, not readily biodegradable, sterilant Sodium Benzoate just gives full play to germicidal action in acid condition, and produces this dust-inhibitor and need heating just can complete, and complex process, production cost is high, is unfavorable for promoting.
The Party Central Committee, State Council pay much attention to prevention and control of air pollution work.In September, 2013, State Council issued " prevention and control of air pollution plan ", and side government in all parts of the country has successively put into effect " prevention and control of air pollution detailed rules and regulations ", in all detailed rules and regulations, had made detailed job placement to dust pollution control." prevention and control of air pollution action plan " is issued and is implemented on further investigation, the basis of repeatedly proving, embody central scientific and precise, practical, the attitude highly responsible to the people and adhere to that people-oriented, put forth effort environmental protect, the firm resolution of rights and interests of protecting public health; So seek a kind of dust-inhibitor that is multi-functional, efficient, environmental protection and saving resource become our research and development focus in the industry.

Table 1 Pyatyi wind-force blowing down strokes the windage loss rate after 5 minutes
The windage loss rate after 5 minutes is brushed under table 2 fresh gale power
Draw from table 1 and 2, except concentration be 0.03% dust-inhibitor comparatively large in fresh gale power leeward loss rate, the dust-inhibitor of other massfractions all has good anti-dust effect.When the storage time is shorter, this concentration or higher concentration can be used to spray, windage loss rate is more greatly because solidification shell occurs damaged, and the coal of the inside is blown away in a large number, and possible reason is sprayed not evenly, and solidifying shell thickness is differed; Consider that laboratory uses little spray bottle atomized spray, fountain height is few, and surging force is very little, adopt water blast gun or fog gun during a large amount of sprinkling, surging force is large, and unit surface fountain height is larger, the infiltration of dust-inhibitor in coal is darker, and solidification shell is thicker, and anti-dust effect may be better.
The above embodiment, just better embodiment of the present invention, be not limit the scope of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application the scope of the claims change or modify, and all should comprise in patent claim of the present invention.
