污水提升泵站的節(jié)能方法研究

發(fā)布時間:2019-04-16 12:41
【摘要】:污水提升泵站是城市排水系統(tǒng)不可缺少的一部分,承擔著城市生活污水、生產(chǎn)廢水排放任務,保障了城市健康發(fā)展,給人們生活提供了良好的居住環(huán)境。 本文針對國內城市污水提升泵站運行管理過程中存在的一些能耗問題進行了分析總結,提出一系列節(jié)能降耗的方法,并闡述其具體的節(jié)能原理。著重就水泵選型、泵的啟閉控制、泵站前池流態(tài)對泵站節(jié)能的影響進行了研究。 一般水泵選型是以遠期設計揚程和流量作為依據(jù),本論文在此基礎上,考慮了近遠期平均時流量和逐年流量變化值的影響,優(yōu)選出年費用最低的水泵選型組合,,為設計人員提供一種更為全面的水泵選型方法。 污水提升泵站運行時的水位變化對水泵啟閉數(shù)量以及調定泵的搭配運行有一定的影響,本論文以能耗最優(yōu)為目標,流量、運行效率以及水泵臺數(shù)為約束條件,利用JAVA軟件編程,得到水位差與組合泵啟閉臺數(shù)調節(jié)的關系,從而有利于泵站操作人員快速、精確地對泵站進行調節(jié)。 泵站前池的流態(tài)也是影響水泵吸水效率的一個關鍵因素,本文借助CFD工具,對泵站前池進行流態(tài)模擬,為前池改造提供依據(jù),從而達到泵站節(jié)能的效果,結果表明,設置1.5m分隔墻是最佳前池改造方式。
[Abstract]:Sewage lifting pump station is an indispensable part of the urban drainage system. It undertakes the task of municipal sewage discharge and production wastewater discharge, which guarantees the healthy development of the city and provides a good living environment for people's lives. In this paper, some energy consumption problems existing in the operation and management of domestic municipal sewage lifting pumping stations are analyzed and summarized, and a series of methods of energy saving and consumption reduction are put forward, and the specific energy saving principles are expounded. The influence of pump type selection, opening and closing control of pump and flow pattern in front of pump station on energy saving of pump station is studied in this paper. The general pump selection is based on the forward design head and flow rate. On this basis, the paper considers the influence of the average flow rate and the annual flow rate change value in the near and long term, and optimizes the selection combination of the water pump with the lowest annual cost. It provides a more comprehensive method of pump selection for designers. The change of water level during the operation of sewage lifting pumping station has certain influence on the quantity of pump opening and closing and the matching operation of regulated pump. In this paper, the optimal energy consumption is the goal, the flow rate, the operating efficiency and the number of pump stations are the constraint conditions, and the JAVA software is used to program the pump. The relationship between the water level difference and the number of opening and closing units of the combined pump is obtained, which is helpful for the operator of the pump station to adjust the pump station quickly and accurately. The flow pattern of the front pool of the pump station is also a key factor affecting the pump suction efficiency. This paper simulates the flow pattern of the front pool of the pump station with the help of the CFD tool, which provides the basis for the reconstruction of the front pool, and thus achieves the energy saving effect of the pump station. Setting 1.5 m separation wall is the best way to reform the front pool.
