Problems solved by technology

[0009] (3) Local residents cannot use other clean energy sources
The main source of income for local residents is planting, but the per capita land area is only 0.84 mu, and the land is barren, so they can only grow corn, and the yield is not high. The corn grown by most villagers is only enough for self-sufficiency, and the annual per capita income is tens of yuan If it is less than 500 yuan, food and clothing cannot be solved, and some families still light kerosene lamps, so it is a luxury to be able to eat enough, and they cannot afford to buy clean fuels such as electricity and liquefied petroleum gas.
[0031] 5. Fluorine volatility

Embodiment Construction

[0064] The combined fuel composition in this technology includes:

[0065] 1. Pulverized coal

[0066] 2. Soil clay layer

[0067] 3. Limestone

[0068] The pulverized coal is coal used in the homes of residents in the sick area.

[0069] The clay is the clay layer of Quaternary soil in the diseased area (used as a binder for coal burning or making briquettes and briquettes).

[0070] The limestone is Permian or Ordovician limestone (as a fluorine-fixing agent).

[0071] The mixture of the above three is used as the daily fuel for local residents.

Abstract

The invention discloses a fluorine-fixing technology in the Tylototriton western endemia flurosis of composite fuel based on dust coal, soil stick layer and limestone, which is characterized by the following: affirming optimum proportion of dust coal / soil stick layer / limestone at 5:1:1 and optimum grain of limestone between 0.4-0.2 mm; making fluorine-fixing rate at 92 percent; obtaining composite fuel component easily; discarding present modified technology of stove chimney; fitting for spreading widely.

Description

Technical field [0001] The invention relates to a daily life combined fuel composed of pulverized coal, a soil clay layer, and limestone. The combined fuel is a combined fuel for preventing endemic fluorosis of residents in western Guizhou. Background technique [0002] Guizhou Province is the province with the most serious endemic fluorosis in my country, among which Zhijin, Bijie, Dafang and Weining counties are particularly serious. The epidemiological survey results show that in Hehua Village, Chengguan Town, Zhijin County, 80% of patients suffer from skeletal fluorosis, and at least one member of almost every family has lost the ability to work or has been paralyzed; the local health department in 2003 In the newly discovered village of Puweng Township, Zhijin County, the hardest hit by fluorosis, the incidence of dental fluorosis among children aged 8 to 12 is as high as 99.6%, and the incidence of skeletal fluorosis is as high as 76% for children over 16 years old, which i...
