Chinese patents have disclosed invention patents with application numbers 90103986.1, 94118457.9, 99124403.6, 00111080.2, 200610106951.2. These invention patents introduce various briquette binders, but these binders are mainly for industrial briquettes, and Only the effect of binder on pulverized coal with sulfur is studied, and the effect on the release of fluorine pollutants during the combustion of briquettes is not involved
In general, there is no relevant research on civil briquette binders that can simultaneously remove fluorine and sulfur pollutants and can be used in the prevention and treatment of coal-fired fluorosis at home and abroad.

Embodiment 1

[0023] The actual application effect of the civil briquette binder of the present invention was verified on the spot in a briquette plant in Zhaoyang District, Zhaotong City, Yunnan Province, and the experiment was carried out in October 2010. There are two kinds of experimental materials: one is the "traditional honeycomb coal" produced by the honeycomb coal plant using clay-type binder; the other is the "new honeycomb coal" prepared by using the civil briquette binder of the present invention.

[0024] In this embodiment, the "traditional honeycomb briquette" is prepared by mixing pulverized coal, clay, and water, using a honeycomb briquette machine. Specific steps are as follows:

[0025] (1) The coal to be prepared into briquettes is crushed with a crusher;

[0026] (2) Weigh 80 kg of pulverized coal, add 20 kg of clay, and stir evenly with a mixer, add an appropriate amount of water and further mix, and then use a briquette machine to compress the "traditional briquette".

Embodiment 2

[0055] In Zhenxiong County, a severely affected area of ​​coal-burning fluorosis in Zhaotong City, Yunnan Province, the effect of the present invention on the prevention and control of coal-burning fluorosis was verified. The experiment was conducted in October 2010. In a severely ill village of coal-burning fluorosis in Zhenxiong County, Zhaotong City, 6 farmers with basically the same barn structure were selected to participate in the experiment. Farmers 1 and 2 use the "traditional slime" made by mixing pulverized coal with clay and mixing with appropriate amount of water to bake the newly harvested corn, while farmers 3, 4, 5, and 6 use pulverized coal to mix the binder of the present invention The "new slime" mixed with a proper amount of water is used to roast the newly harvested corn. All participating farmers use the same coal. It should be noted that, according to the coal consumption habits and convenience of local farmers, in the coal-burning fluorosis areas of sout...

Abstract

The invention provides a civil version coal adhesion agent and a preparation method thereof. The adhesion agent comprises the following components in percentage by mass: 33 to 35 percent of Carboniferous siliceous limestone, 60 percent of modified intermediate Triassic period silicon-containing dolomite and 5 to 7 percent of modified Triassic period feldspar quartz sandstone, wherein modified materials are obtained by activation at a certain temperature. The adhesion agent has a simple preparation process, and required raw materials are widely distributed in a large number of regions in China, are easy to acquire and have low cost; the adhesion agent does not generate secondary pollution, is suitable for any coal variety and has the effects of a fluorine fixing agent and a sulfur fixing agent of fire coal, and civil version coal prepared by the adhesion agent has high combustibility, and extremely low escaping rate of pollutants such as fluorine, sulfur and the like during combustion,and has a good environmental benefit; and particularly, in a coal combustion type fluorosis region, when the civil version coal prepared by the adhesion agent is used for baking foods, fluorine pollution of the fire coal to the baked foods can be greatly reduced, the condition that the problem of coal combustion type fluorosis in China is radically solved from a fluorine pollution source is facilitated, and social benefits are obvious.

Description

Technical field [0001] The invention relates to the field of civil coal powder forming binders, and relates to the technical field of environmental protection and clean combustion of civil coal briquette and the field of coal-fired fluorosis prevention and control, in particular to a civil coal briquette that can be used for the prevention and treatment of coal-fired fluorosis Agent. Background technique [0002] Coal occupies an important position in my country's energy structure. my country's energy production and consumption have long been dominated by coal. In particular, in my country's vast small and medium-sized towns and rural areas, coal still occupies a large proportion of residents' cooking, heating and other production and living fuels. According to statistics, there are more than 100 million coal-burning stoves for civilian cooking in the country. As we all know, without any technical treatment, the SO released from coal burning 2 Such pollutants are not only easy ...
