石家庄石一泵业对脱硫循环泵改进的分析

电厂脱硫装置大多为石膏湿法烟气脱硫装置,脱硫循环泵脱硫装置运转的中心输送介质为石膏固相物以及硫酸、盐酸等酸性物质的物料这些脱硫循环泵泵壳、叶轮等部位呈现严重的气蚀、磨损和腐蚀等现象,影响循环泵的运用寿命及运转效率,影响机组的安全运转。DT脱硫泵能适应这种环境,一台全年不连续运转的400KW浆液循环泵每年耗电量达二百多万度,因此脱硫循环泵正确使用和维护是保证企业正常运转的一个基础。

叶轮和泵壳的表面凹坑和粗糙度增加了流动阻力。

 

叶片间隙会产生大量涡流,流量下降,能量消耗。

 

叶轮及泵壳磨损,导致泵口环间隙增大,泵损。

这些原因会造成能耗加大。以500KW的浆液脱硫泵为例。每台泵每年要多损耗17万度左右的电。还要更换叶轮。直径在600mm的叶轮,那你们好,侧板等易损件的成本在20-62万元左右。维修成本很高。所以,提高脱硫循环浆液泵的效率。改进工艺,对节能降耗有非常大的意义。

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.
