德固特(300950.SZ):取得1項實用新型專利證書 為一種空氣預熱器
格隆匯 03-11 19:20

格隆匯3月11日丨德固特(300950.SZ)公佈,公司於近日取得中華人民共和國國家知識產權局頒發的1項實用新型專利證書,專利名稱為一種空氣預熱器。

本實用新型專利涉及一種空氣預熱器,尤其涉及煤制煤氣工藝用將空氣温度加熱到 500°C以上的空氣預熱器,包括換熱管、折流板、殼體、熱側管板、冷側管板、膨脹器、煙箱一、煙箱二、空氣進口、空氣出口、分流板、旁路管,熱側管板位於高温煙氣側,為雙層管板,其內部通入強制冷卻空氣,冷側管板位於低温煙氣側,在與其相鄰的折流板間設一塊分流板,分流板將一部分空氣引流到靠近冷側管板一側的空腔,並經旁路管引入至殼體中間某處,與另一部分空氣匯合,因此,兩塊管板均得到了有效的冷卻,避免了嚴重的熱應力不均勻,進而保證了設備安全運行,保證空氣在殼程中尤其是管板處均勻分佈,為管板提供均勻有效的冷卻,避免嚴重的温差熱應力而導致的失效。本技術已應用於公司部分產品。

上述實用新型專利的取得不會對公司生產經營產生重大影響,但有利於公司進一步完善知識產權保護體系,發揮自主知識產權優勢,促進技術創新,提高公司的綜合競爭能力。
