Description
Technical field
The utility model relates to a kind of pipeline heating power rinse-system, is applicable to the flushing of power plant closed-type circulating cooling water system pipeline.
Background technology
Closed-type circulating cooling water system complexity in the generation current factory, the flushing resistance is bigger, traditional normal-temperature water purging method that it adopts, exist washing time long, wastewater discharge is big, the power consumption height, the water quality variation often appears in system's normal operation period, causes problems such as equipment pipe obstruction, the deterioration of heat exchange effect.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and provides that a kind of to have method easy, less energy consumption, the pipeline heating power rinse-system of the advantage that developing result is good.
For achieving the above object, the utility model adopts following technical scheme:
A kind of pipeline heating power rinse-system, it comprises flushing line and treats that flushing device, described flushing line are provided with the expansion tank that is connected with Steam Heating vapour source that expansion tank is connected with at least one enclosed water pump; Between the adjutage of expansion tank and enclosed pump entrance, be provided with one section and quicken pipeline and the driven valve that water temperature promotes, promote rinse water temperature to 60 ℃; In the minimum point of system and the relative big caliber pipeline place of distal-most end at least two flush discharge mouths are set.
Described enclosed water pump has two, their paired runnings.
The utility model does not change existing flushing line and all kinds of flushing devices for the treatment of that are connected with pipeline, but in system, added Steam Heating vapour source, design is quickened pipeline and the driven valve that water temperature promotes for one section between expansion tank adjutage and enclosed pump entrance, promotes rinse water temperature to 60 ℃ rapidly; Big caliber place in the minimum point and the distal-most end of system is provided with at least 2 flush discharge mouths, between flush period and flushing the dirt that wash is in time got rid of totally the accelerated wash-out process after finishing; The advancing of the equipment user that caliber is bigger, water return pipeline are done interim short circuit, and the advancing of caliber small device user, water return pipeline are not done interim short circuit, just disconnect adpting flange and do intermittent discharge, realize system's slight drag, big flow flushing; 2 enclosed water pumps of paired running guarantee to provide system's flushing required power and flow.
Concrete rinsing step is: after (1) system pipeline and expansion tank water-filling, the venting, start 2 enclosed water pumps, closed circulation termination of pumping after 1 hour, discharge water; (2) system pipeline and expansion tank again water-filling, the venting after, start 2 enclosed water pumps, open driven valve, feed heating steam to expansion tank, treat to cut off after water temperature rises to 60 ℃ and add hot vapour source, system's flushing termination of pumping after 2 hours is taked multiple spot, intermittent discharge mode with intrasystem water emptying between flush period and after the flushing end, and is treated that system pipeline cools down fully; (3) repeated execution of steps (2) flushing is till rinse water quality testing is qualified.
These the beneficial effects of the utility model are: (1) system change cost and workload little, only need increase by one tunnel Steam Heating vapour source, the temporary pipeline of control system water temperature and driven valve, the advancing of the big caliber of short circuit, return pipe; (2) device is simple, practical; (3) developing result is good, does not stay the dead angle, and washing time is short, and water consumption and power consumption are little; (4) do not need to add chemical agent, pollution-free.
