As further optimization, for the ease of blowdown and draining, the bottom of described casing is provided with is with valvular manual drainage pipeline, when automatic pollution discharge is undesired, can by manually carrying out blowdown, guarantee that system's blowdown is normal.
The utility model is simple in structure; can be used for that the operating circulating water system renovates or the interchanger of maintenance process after finishing cleans separately pre-film; guarantee that the interchanger behind the pre-film of cleaning reaches at the fine and close protective membrane of its surface formation one deck, slows down the requirement of interchanger corrosion.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is automatic blowdown valve, and 2 for analysing sampling valve, 3 adding of agent batch meters, 4 is automatic water compensating valve, 5 is overflow weir, 6 is the clorox batch meter, 7 is sour batch meter, and 8 is lift pump, and 9 is the Controlling System housing, 10 is that online ORP monitor, 11 is liquidometer, 12 is the manual blowdown valve, and 13 is casing, and 14 is that online pH monitor, 15 is online monitoring turbidimeter.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, the pre-film device of a kind of cleaning, comprise the casing 13 with water outlet and water-in, the top of casing 13 is provided with adding of agent batch meter 3, water outlet is provided with on-line oxidation reduction potential ORP monitor 10, online PH monitor 14, online monitoring turbidimeter 15, the top of casing 13 is provided with sour batch meter 7 and the pre-film device of clorox batch meter 6 whole integrated cleanings is provided with Controlling System, the pH value that requires when cleaning pre-film can be set, chlorine residue (can record by the ORP value), turbidity, liquid level, Controlling System is according to online pH monitor, online ORP monitor, online monitoring turbidimeter, liquidometer institute's value of feedback and set(ting)value compare, automatically adjust within setting range for corresponding magnetic valve signal feedback according to difference, need not personnel operation.The bottom of casing 13 is provided with has the sampling line of analysing sampling valve, the initial stage water-in of casing is arranged at the side of casing, the bottom of cleaning pre-film backwater water-in in the casing is provided with the overflow weir 5 that links to each other with cabinet wall, the water outlet of casing is provided with lift pump 8, the casing outer setting has the online liquidometer 11 that is communicated with box house, and the bottom of casing 13 is provided with is with valvular manual drainage pipeline.
