  1. This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time

    該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。
  2.

  3. The main works have been done as follow : ( 1 ) after a great deal of literatures are read, the paper introduces the main ways of the flue gas desulfurization, and the development status of dcs ; ( 2 ) through the analysis of the former dcs system in the plant, the desire about the rebuilding of dcs is put ; the characteristic of the planning dcs system is introduced ; ( 3 ) according to the characteristic of the wet limestone - gypsum flue gas desulfurization, the main factor about influencing the efficiency of desulfurization is analyzed ; ( 4 ) some tests are done, which are the reduction and enhancement of the flue gas quantity, and the disturbing test of the starting and stoping the circulation of the serum in the absorbing tower. the paper lists some actual run curves

    本文完成了以下主要工作：在閱讀了大量文獻資料的基礎上，介紹了火電廠煙氣脫硫的主要方法，以及dcs的發展狀況；通過對本廠脫硫裝置原有dcs系統的分析，提出了對dcs改造的要求；介紹了擬選擇dcs的特點；根據濕式石灰石石膏法煙氣脫硫的特點，分析了影響系統脫硫效率的主要因素；進行了吸收塔煙氣量減少、增加，啟停吸收塔漿液循環泵擾動試驗，並給出了部分實際運行曲線。
