水電站布設(shè)攔污排技巧
浮設(shè)在進(jìn)水口前一定水域的前沿，用以攔截水流中漂浮的排架式攔污設(shè)備。在漂浮雜物較多的河道上，如僅設(shè)攔污柵，會使柵前的污物大量堆積，清理不及時(shí)，將堵塞柵孔，影響 水。在攔污柵前設(shè)攔污排，兩者結(jié)合使用，效果！
柏泰聚乙烯攔污排浮筒設(shè)備連接使用安全 ，因攔渣裝置浮筒材料外殼采用食品LLDPE為原料內(nèi)部聚苯乙烯填充發(fā)泡，浮筒韌性強(qiáng)，外殼強(qiáng)度高，即使是汛期受到強(qiáng)烈的樹木雜物撞擊也不會破裂！單個(gè)浮筒浮力大，有整體式和兩片組合式，施工安裝簡單，使用 可達(dá)15年以上！
水電站布設(shè)攔污排技巧浮式攔污排的縱向軸線與攔污排 水流主流方向的夾角不宜過大。水流主流方向應(yīng)按正常發(fā)電和泄洪兩種工況來分別考慮。攔污排縱軸線與主流方向的夾角越小，污物對攔污排的沖擊力就越小，污物繞過攔污排的可能性就越小，攔污效果也就越好；此外，夾角越小，沿?cái)r污排軸線的分向力就越大，導(dǎo)漂效果就越好。 據(jù)工程經(jīng)驗(yàn)，建議該夾角的角度小于30°。
Floating is located at the front of a certain water area before the intake to intercept the floating type of fouling equipment in the water. In rivers with more floating debris, if only a barrier is set up, a large amount of debris will accumulate in front of the barrier, and if the cleaning is not timely, the barrier hole will be blocked and the water diversion will be affected. In the front of the trash rack, a sewage platoon will be set up. The combination will be effective.
Botai polyethylene contamination removal buoy equipment connection is safe and reliable, because the slag removal device buoy material shell using food-grade LLDPE as raw material filled with polystyrene foam, buoy toughness, high shell strength, even in flood season by strong tree debris impact will not break! The single buoy has a large buoyancy, has the integral type and two piece combination type, the construction and installation are simple, and the service life can be more than 15 years.
The angle between the longitudinal axis of the floating sewage interception row and the main flow direction of the sewage interception row should not be too large. The main direction of water flow should be considered separately according to the two conditions of normal power generation and flood discharge. The smaller the angle between the vertical axis and the main direction of the interception row, the smaller the impact force of the pollutant on the interception row, the less the possibility of the pollutant bypassing the interception row, and the better the interception effect; moreover, the smaller the angle, the greater the dividing force along the axis of the interception row, and the better the drift conduction effect. According to the engineering experience, it is suggested that the angle of the included angle is less than 30 degrees.
