【摘要】：利用地下水力封洞庫群儲備石油及其產(chǎn)品現(xiàn)已成為世界各國主要的一種儲備方式：地下水力封洞庫群開挖斷面大,洞庫縱橫交錯成網(wǎng)狀等特點必將會對施工帶來許多問題,尤其是在施工通風過程中且國內(nèi)外少有類似經(jīng)驗可以借鑒：本文以某地下水力封LPG洞庫群第四階段(施工高峰期)通風方案為依托,主要研究了以下4方面的內(nèi)容并得到相應結論,研究成果可為類似工程起到借鑒和指導作用： 1.通過對國內(nèi)外相關施工通風安全衛(wèi)生標準的類比并根據(jù)類似工程的施工經(jīng)驗,確定了地下洞庫施工通風空氣安全衛(wèi)生標準；通過對相關通風方式的查閱并結合類似工程施工通風經(jīng)驗,對地下水力封洞庫群施工通風方式的選擇應注意的問題作了說明。 Z對施工高峰期間洞庫群需風量計算、漏風量計算,沿程風壓和局部風壓損失計算,驗證擬定方案通風設備性能(風量和風壓)是否滿足洞庫群通風的需要。計算表明在風在良好的管理和布置條件下,施工高峰期間通風設備性能(風量和風壓)基本能滿足庫群施工通風的需要。 3.建立丙烷洞庫群通風計算模型,通過三維數(shù)值模擬和應用網(wǎng)絡通風理論,經(jīng)過FLLENT軟件計算得到丙烷洞庫群的風速和污染物濃度的分布,從而判定洞庫內(nèi)空氣是否滿足地下洞庫施工通風空氣安全衛(wèi)生標準。通過數(shù)值模擬計算發(fā)現(xiàn),在對已修建完畢的洞庫采取封堵措施后,整個丙烷洞庫群的風速和污染物濃度滿足標準中的要求。 4.建立了15組風倉(GAMBIT有限元數(shù)值模型,通過FLUENT軟件進行模擬計算,得到了不同風倉尺寸和風機布置形式對軸流風機效率的影響規(guī)律并確定了軸流風機效率最大時的風倉尺寸和風機布設形式。計算結果表明,在風倉高度固定為9m的條件下,風倉長度取30m、寬度取10m時,風倉兩側的風機效率最高,因此可確定風倉的最佳尺寸；另外,在此基礎上風倉中間不設置隔板,風倉每側風機分列布置且風機間橫向和豎向間距都為2m及風機間不設置隔板時,可得到最佳合理的軸流風機效率。
[Abstract]:Taking advantage of the characteristics of underground water sealing cavern reservoir group to store oil and its products has become one of the main storage methods in the world: the excavation section of underground water force seal hole reservoir group is large and the tunnel reservoir is crisscrossed into a network, which will inevitably bring many problems to the construction. Especially in the process of construction ventilation and few similar experience at home and abroad can be used for reference: this paper is based on the ventilation scheme of the fourth stage (construction peak period) of a groundwater force seal LPG cavern group. This paper mainly studies the following four aspects and draws the corresponding conclusions. The research results can be used for reference and guidance for similar projects: 1. Based on the analogy of relevant construction ventilation safety and hygiene standards at home and abroad and according to the construction experience of similar projects, the ventilation and air safety and sanitation standards for underground cavern construction are determined. By consulting the relevant ventilation modes and combining with the construction ventilation experience of similar projects, the paper explains the problems that should be paid attention to in the selection of ventilation modes in the construction of underground water force seal cavern group. Z is used to calculate the air volume, air leakage, wind pressure and local wind pressure loss of the tunnel reservoir during the construction peak period, to verify whether the ventilation equipment performance (air volume and wind pressure) of the proposed scheme can meet the ventilation needs of the tunnel reservoir group. The results show that under the condition of good wind management and arrangement, the ventilation equipment performance (air volume and wind pressure) can basically meet the needs of the construction ventilation of the reservoir group during the construction peak period. 3. The ventilation calculation model of propane cavern group was established. The distribution of wind speed and pollutant concentration of propane cavern group was calculated by using FLLENT software through three-dimensional numerical simulation and network ventilation theory. Therefore, it is determined whether the air in the cavern meets the safety and hygiene standards of ventilation and air in underground cavern construction. Through numerical simulation, it is found that the wind speed and pollutant concentration of the whole propane cavern group meet the requirements of the standard after the sealing measures have been taken for the constructed cavern. 4. A finite element numerical model of 15 groups of wind bunkers was established and simulated by FLUENT software. The effects of different air bin size and fan layout on the axial fan efficiency are obtained and the wind bin size and fan layout form are determined when the axial fan efficiency is maximum. The calculation results show that when the height of the air chamber is fixed to 9 m, the fan efficiency on both sides of the air chamber is the highest when the length of the air chamber is 30 m and the width is 10 m, so the optimum size of the air bin can be determined; in addition, no partition is provided in the middle of the air chamber on this basis. The optimum axial fan efficiency can be obtained when the wind bin is arranged separately and the horizontal and vertical spacing between the fans is 2 m and the partition is not set in the fan room.
