【摘要】：在我國(guó)能源結(jié)構(gòu)中煤炭占主要地位,眾所周知,煤炭的產(chǎn)量直接影響我國(guó)的經(jīng)濟(jì)發(fā)展情況,但是我國(guó)煤炭大多存儲(chǔ)于千米以下,開采困難,面臨嚴(yán)重的地質(zhì)災(zāi)害。即高地溫、高地壓、高瓦斯。 高地溫主要體現(xiàn)在暴露圍巖的溫度升高,礦井井下空氣溫度升高。這些問(wèn)題嚴(yán)重影響煤礦企業(yè)的安全、高效的開采,成為制約我國(guó)煤礦發(fā)展的關(guān)鍵因素之-目前,煤礦對(duì)于井下高溫的治理方法主要是改變通風(fēng)方式、物理降溫、減少工作時(shí)間、化學(xué)降溫、隔離熱源、空調(diào)降溫等。其中機(jī)械降溫效果最為明顯,礦井機(jī)械降溫主要是應(yīng)用制冷劑制冷的原理,降低礦井井下空氣的溫度。 但是,空調(diào)降溫還存在一些問(wèn)題。如占地面積大,嚴(yán)重影響采煤或掘進(jìn)工作面的通風(fēng)；噪音較大；采用制冷劑的壓縮特性產(chǎn)生冷源,一旦制冷劑泄露,對(duì)采煤或掘進(jìn)工作面造成嚴(yán)重污染；制冷效果相對(duì)煤礦企業(yè)的要求還有一定的差距。 局部降溫系統(tǒng)沒(méi)有達(dá)到煤炭企業(yè)的要求的主要原因是制冷設(shè)備達(dá)不到要求。因此本論文將進(jìn)行新型礦井降溫技術(shù)的研究,以滿足煤礦企業(yè)對(duì)降溫的要求。本論文研究的技術(shù)原理為半導(dǎo)體制冷原理,因?yàn)榘雽?dǎo)體制冷有著獨(dú)到的優(yōu)勢(shì),如制冷設(shè)備很小、制冷快、噪音小、能耗少等。 本論文通過(guò)半導(dǎo)體制冷設(shè)備的可行性研究、實(shí)驗(yàn)對(duì)象的模擬、實(shí)驗(yàn)室的驗(yàn)證和現(xiàn)場(chǎng)應(yīng)用設(shè)想四部分構(gòu)成。制冷設(shè)備的可行性研究主要包括半導(dǎo)體制冷設(shè)備的設(shè)計(jì)和理論計(jì)算設(shè)備的制冷效率。實(shí)驗(yàn)對(duì)象的模擬主要是理論計(jì)算工作面的需冷量大小,與半導(dǎo)體制冷設(shè)備的制冷量比較,確定半導(dǎo)體制冷技術(shù)的可行性。最后通過(guò)實(shí)驗(yàn)室試驗(yàn),確定半導(dǎo)體制冷技術(shù)中的半導(dǎo)體制冷設(shè)備的型號(hào)和技術(shù)參數(shù)。論文第四部分主要是此技術(shù)應(yīng)用于煤礦中的設(shè)想和應(yīng)用前景。 半導(dǎo)體制冷技術(shù)在煤礦中的應(yīng)用需要大量的試驗(yàn)和技術(shù)投入,本論文主要是半導(dǎo)體制冷技術(shù)應(yīng)用于煤礦的基礎(chǔ)理論研究,為以后的半導(dǎo)體制冷技術(shù)在煤礦中的應(yīng)用提供技術(shù)支持。
[Abstract]:Coal occupies the main position in the energy structure of our country. As we all know, the output of coal directly affects the economic development of our country. However, most of the coal in our country is stored below km, so it is difficult to exploit and face serious geological disasters, that is, highland temperature. High ground pressure, high gas. The high ground temperature is mainly reflected in the temperature rise of exposed surrounding rock and the rise of air temperature in underground mine. These problems seriously affect the safety and efficient mining of coal mining enterprises, and become one of the key factors restricting the development of coal mines in China. In coal mines, the main treatment methods for underground high temperature are to change the ventilation mode, reduce physical cooling, reduce working hours, reduce chemical cooling, isolate heat sources, cool air conditioning, etc. Among them, mechanical cooling effect is the most obvious. The cooling of mine machinery is mainly based on the principle of refrigerant refrigeration to reduce the temperature of underground air. However, there are still some problems in cooling air conditioning, such as large area of land, which seriously affects ventilation of coal mining or tunneling face, loud noise, cold source produced by compression characteristics of refrigerant, and once refrigerant leaks, It causes serious pollution to coal mining or tunneling face, and the refrigeration effect is far behind the requirements of coal mining enterprises. The main reason why the local cooling system does not meet the requirements of coal enterprises is that the refrigeration equipment can not meet the requirements. In order to meet the requirements of coal mine enterprises, the technical principle of this paper is semiconductor refrigeration, because semiconductor refrigeration has unique advantages, such as very small refrigeration equipment, fast refrigeration, low noise, less energy consumption and so on. In this paper, the feasibility of semiconductor refrigeration equipment, experimental object simulation, The feasibility study of refrigeration equipment mainly includes the design of semiconductor refrigeration equipment and the refrigeration efficiency of theoretical calculation equipment. The simulation of experimental object is mainly theoretical calculation. The amount of cooling required in the working face, Compared with the refrigeration capacity of semiconductor refrigeration equipment, the feasibility of semiconductor refrigeration technology is determined. The model and technical parameters of semiconductor refrigeration equipment in semiconductor refrigeration technology are determined. Part 4th is mainly about the assumption and application prospect of this technology in coal mine. The application of semiconductor refrigeration technology in coal mine requires a lot of experiments and technical input. This paper is mainly about the basic theory research of semiconductor refrigeration technology applied in coal mine. It provides technical support for the application of semiconductor refrigeration technology in coal mine.
