根据计算月燃气消耗的日或周不均衡工况计算储气容积(步骤)Calculate the gas storage volume according to the calculation of daily or weekly imbalance of monthly gas consumption (step) 气源按计算月最大日平均小时供气量均匀供气Gas supply is uniform according to the calculated monthly maximum daily average hourly gas supply 设每日气源供气量为100万m3The daily air supply is set as 1 million m3 则每小时平均供气量为100/24=4.17万m3Then the average air supply per hour is 100/24= 41,700 m3 计算日或周的燃气供应量的累计值Calculate the cumulative value of daily or weekly gas supply; 计算日或周的用气量的累计值Calculate the cumulative daily or weekly gas consumption; 计算每小时末燃气的储存量Calculate gas storage at the end of each hour 燃气供应量与用气量的累计值之差The cumulative difference between gas supply and gas consumption 计算所需储气容积Calculate the required gas storage volume 计算出的最高与最低储气量之差The calculated difference between the maximum and minimum gas storage
低压湿式罐Low pressure wet tank 结构structure 水槽内放置钟罩和塔节,钟罩和塔节随着燃气的进出而升降。并利用水封隔罐内外气体来储存燃气的容器。A bell jar and tower joint are placed in the tank, and the bell jar and tower joint rise and fall with the passage of gas. And use water to seal the gas inside and outside the tank to store the gas in the container. 罐的容积随燃气量而变化The volume of the tank varies with the amount of gas 分类(钟罩的升降方式)Classification (how the bell jar is raised and lowered) 直立罐:水槽外壁上带有导轨立柱Upright tank: the outer wall of the tank is provided with guide column 螺旋罐:钟罩自身外壁上带有螺旋状轨道Screw jar: the bell jar itself has a spiral track on the outer wall 在北方采暖地区冬季要采取防冻措施,因此管理较复杂,维护费用较高。In the northern heating area, winter measures should be taken, so management is more complex and the maintenance fee is higher. 由于塔节经常浸入、升出水槽水面,因此必须定期进行涂漆防腐。Because tower section often immerses, rises the water surface of cistern, because this must carry on regularly coating anticorrosive.
