        石家莊石一泵業對脫硫循環泵改進的分析

        電廠脫硫裝置大多為石膏濕法煙氣脫硫裝置,脫硫循環泵脫硫裝置運轉的中心,輸送介質為石膏固相物以及硫酸、鹽酸等酸性物質的物料,這些脫硫循環泵泵殼、葉輪等部位呈現嚴重的氣蝕、磨損和腐蝕等現象,影響循環泵的運用壽命及運轉效率,影響機組的安全運轉。DT脫硫泵能適應這種環境,一臺全年不連續運轉的400KW漿液循環泵每年耗電量達二百多萬度,因此脫硫循環泵正確使用和維護,是保證企業正常運轉的一個基礎。

         石家莊石一泵業對脫硫循環泵改進的分析

        葉輪和泵殼的表面凹坑和粗糙度增加了流動阻力。

         

        葉片間隙會產生大量渦流,流量下降,能量消耗。

         

        葉輪及泵殼磨損,導致泵口環間隙增大,泵損。

        這些原因會造成能耗加大。以500KW的漿液脫硫泵為例。每臺泵每年要多損耗17萬度左右的電。還要更換葉輪。直徑在600mm的葉輪,那你們好,側板等易損件的成本在20-62萬元左右。維修成本很高。所以,提高脫硫循環漿液泵的效率。改進工藝,對節能降耗有非常大的意義。

           Most of the desulfurization devices in power plants are gypsum wet flue gas desulfurization devices. The desulfurization circulating pump is the operation center of the desulfurization device. The transportation medium is gypsum solid and acid materials such as sulfuric acid and hydrochloric acid. These will cause serious cavitation, wear and corrosion on the pump shell, impeller and other parts of the desulfurization circulating pump, and affect the service life and operation efficiency of the circulating pump, Affect the safe operation of the unit. DT desulfurization pump can adapt to this environment. A 400KW slurry circulating pump which does not run continuously in the whole year consumes more than 2 million kwh of electricity every year. Therefore, the correct use and maintenance of the desulfurization circulating pump is a foundation to ensure the normal operation of the enterprise.

        The surface pits and roughness of impeller and pump shell increase the flow resistance.

            A large number of vortices will be generated in the blade gap, resulting in the decrease of flow rate and energy consumption.

        Impeller and pump shell wear, resulting in the increase of pump ring clearance, pump damage.

        These reasons will increase energy consumption. Take 500kW slurry desulfurization pump as an example. Each pump consumes about 170000 kwh more electricity every year. Also replace the impeller. For impeller with diameter of 600mm, Hello, the cost of vulnerable parts such as side plate is about 200000-620000 yuan. Maintenance costs are very high. Therefore, improve the efficiency of desulfurization circulating slurry pump. Improving the process is of great significance to energy saving and consumption reduction.
