掌握了间歇逆流清洗中各清洗槽污物浓度的计算之后,就可以推算出在一定清洗条件下,什么时候应该换水,以及需要几个清洗槽。现举例说明如下:[例1]设原液污物浓度为50000mg/l,最后清洗槽允许污物的最大浓度为20mg/l。即要求 Co/C_末>2500。由于清洗零件不止一种,假设使用简单清洗条件,η可取0.9(在实际计算中可采用实测值)。(1)先考虑五级清洗由公式(Ⅳ)所算出的数据表及算图中可以查
Having mastered the calculation of the concentration of contaminants in each tank during intermittent counter-current cleaning, it is possible to figure out when it is time to change the water and how many tanks are required under certain conditions of cleaning. The following is an example: [Example 1] The concentration of the original liquid waste is 50000 mg / l, and the maximum allowable concentration of the dirt in the final washing tank is 20 mg / l. That is, Co / C_ end> 2500 is required. Since there are more than one part to be cleaned, assuming that a simple cleaning condition is used, η may be 0.9 (actual values may be used in actual calculations). (1) first consider the five cleaning formula (Ⅳ) calculated by the data table and calculation can check
