Photoelectric rule-based anhydrous mineral separation equipment for eliminating gas and removing radon gas
Technical Field
The invention relates to mineral processing equipment, in particular to waterless mineral processing equipment for eliminating radon gas by photoelectric regulation.
Background
The key part of the ray detection waterless coal dressing and mineral dressing is a multi-pulse time delay control device; the 1997 2.1.h. Hunan Tan City science and technology Committee in Huntington, zhouyun, the invention of the "multi-pulse delay control device" comments: the separation process does not use water washing \8230, and the multi-pulse delay control device has high precision and large delay adjustment range and can meet the separation requirements of various particle raw coals with different diameters.
The multi-pulse delayer developed in 1 st of Yuanyue in 2004 and Zhouyanshun and Zhouyuan in the pilot test process of the industrial operation test of the optoelectronic intelligent coal separator proves that: the desulfurization ash reduction rate reaches 90 percent, which is 2 to 4 percent higher than that of a coal washing plant; the recovery rate of clean coal is as high as 98%, which is about 5% higher than that of a coal washing plant; the photoelectron intelligent waterless coal separation equipment applied by the inventor on the spring and the patentee on the spring in 2007 at 5/8.2008 obtains the patent right with the application number of 200720063126.9 at 8/2. Zhou Chunsheng et al, after summarizing laboratory bench test, industrial pilot test and industrial pilot test, first pilot test engineering construction of optoelectronic intelligent waterless coal separator from 1/2/1997 to 14/2006, at 34 th (total 123 th) mineral engineering research, at 72 th page of 4 th 2019, point out: under the condition of the prior art, the photoelectric intelligent waterless coal dressing and mineral dressing can be realized by using a multi-pulse delayer '+'.
Up to now, air blowers 63 are adopted by domestic and foreign mines to convey compressed air to underground roadways so as to reduce methane CH 4 (g) Concentration, preventing gas disasters; in order to ensure that the gas concentration of the underground coal mine roadway is lower than the gas explosion limit, the gas management agency of the United nations stipulates that: firstly, compressed air is conveyed to a coal mine underground roadway to dilute the methane concentration of the coal mine underground roadway, meanwhile, clear water is sprayed to each mining surface and adjacent roadways to reduce the concentration of coal mining dust, and a methane network is built under the coal mine to allow coal mining; when coal mine underworkings methane CH 4 (g) When the concentration rises to 1.5%, the power supply of all electrical appliances in the underground coal mine roadway must be immediately cut off. Wu guan, shi liang published in mining engineering research 2018 at 9 month 3 (33 rd volume 3 rd phase, total 118 th phase) "the discussion of problems and countermeasures in the gas extraction from the coal mine in the south of the lake" (discussion of mining engineering research): the general fault has less gas, the gas at the inclined shaft part in the near direction is large, the gas content at the inclined angle of the coal bed is small, the thicker the coal bed is, the larger the gas is, and the thicker the soft layering is, the larger the gas is. Aiming at the characteristics that the thicker the coal bed is, the larger the gas is, the thicker the soft layering is, the larger the gas is and the gas disaster is easy to occur, the invention adds the 1 st radon gas removal pipeline system 31 and the 2 nd radon gas removal pipeline system 96 to radically cure the gas disaster.
However, the regulations of the United nations gas administration and the State Bureau of safety and production, neither relate to the extraction of H from the mine underground 2 S(g)、CO(g)、SO 2 (g)、NO X (g) And the technical measures of harmful gases also relate to the problem of eliminating serious harm of radon 222Rn (g) and daughter thereof on the human body of underground staff in the mine underground roadway. Domestic sewage and bezoar of underground staff are dissolved in underground water of a coal mine and decomposed into inorganic substances such as stink toxic gas hydrogen sulfide H2S (g) and the like by microorganisms; h 2 S (g) and NO X (g) And SO 2 (g) The water-soluble polymer is dissolved in underground water such as coal mine and the like, so that the underground water is acidic, and underground workers can carry drinking water to perform underground operation; some coal mines and mines also discharge underground water to well heads, so that not only is the irrigation and water conservancy facilities polluted, but also drinking water sources of local residents are cut off, and the coal mines and the mines solve contradictions to the settlement of pollution cost for farmers; cancellation of 222 Rn (g) and technical measures for damaging the health of underground workers by daughters thereof have not been provided so far.
