槽内换热器发作渗漏处


因为板式换热器的密封周边较长,板片又较薄,在运用过程中可能会呈现渗漏表象。渗漏表象可分为内漏和外漏两种状况。
A、查看冷热介质的进口参数与原规划值是不是相符。若是不相符,应设法调整到原计值。若进口参数已改动,无法调整到原规划值,则应从头进行规划核算,决议增减换热面积或更改流程组合。
B、若是冷、热介质的进口参数与原规划值相符,而出口参数达不到规划值时,则应停机,拆开查看板间有无阻塞或板片结垢等状况,并及时处置。
a、拆开板式换热器,铲除板片表面上的尘垢,擦干后将换热器从头拼装起来。在一侧进行压力为0.2~0.3Mpa的水压实验。滑触线待另一侧流出水后即中止实验,翻开换热器,仔细观察纯水机板片的未试压侧,其间湿的板片即为有孔或裂纹的板片。
b、在现场也可用透光、上色查看办法,查出废板片。

Because of the plate heat exchanger seal around longer, slab and thin, may be present in the process of using leakage appearance.Surface leakage can be divided into two kinds of condition, internal leakage and leakage.A, check the import of cold and hot medium parameter value is consistent with the original planning.If it is not consistent, should try to adjust to the original value.If import parameters has been altered, fail to adjust to the original planning value, should start planning accounting, resolution to increase or decrease in heat transfer area or change process.B, if the import of cold and hot medium parameters are in conformity with the original planning value, while the export parameters reach planning, should stop, open view between with and without blocking or plate state such as scaling, and timely treatment.A plate heat exchanger, apart, wipe out the plate piece of dirt on the surface, after dry heat exchanger will be rebuilt from scratch.On the side pressure of 0.2 ~ 0.3 Mpa water pressure experiment.Sliding contact line to the other side of water after the suspension experiment, turn the heat exchanger, carefully observe the pure water machine without pressure side of the plate, in the wet plate to have a hole or crack of plate.B, on the spot can also be pervious to light, color check method, find out waste plate.
