Description
Technical field
The pre-film device of a kind of local cleaning of circulation cooling water system when the utility model relates to recirculating cooling water system replacing pipe-line equipment.
Background technology
No matter recirculating cooling water system is new system or legacy system, before driving normally to add the water conditioning medicament, all needs to carry out system and cleans pre-film work, cleans pre-film work and is called as the chemically treated key of recirculating cooling water system.Can have things such as chip, foreign material and dust increase and the removable parts pipeline in legacy system, stay unavoidably in the system, the greasy dirt of cooling apparatus is also very serious sometimes, and these foreign material and greasy dirt be not as cleaning up the normal operation of the system that will influence.Therefore, the well-done stable effect of then can increasing water quality of cleaning reduces the generation of corrosion and fouling, improve thermo-efficiency, improve process conditions, guarantee length production cycle, cut down the consumption of energy and prolong work-ing life of equipment.
Because the requirement of technology needs often to change short tube or blind plate 6, change short tube or blind plate 6 and have greasy dirt and corrosion, must clean.Traditional cleaning prefilming method is opened water injection valve 1 to system's water filling as shown in Figure 1 when cleaning, the water injection rate of this moment decide according to the recirculating cooling water system volume, fills with to close water injection valve 1 behind the water and open water pump 2, system's band is pressed move.Flow reduces after system moves for some time, and foreign material, dirt are trapped within the front of screen plate 13, stops water pump 2 operations this moment, opens wash water valve 11, makes the water emptying in the system, extracts screen plate 13 out dirt, foreign material are removed, and carries out matting then.Close wash water valve 11, open water injection valve 1 to system's water filling, open dosing pump 7 simultaneously, to clean soup 9 and from water treatment agent storage tank 8, utilize dosing pump 7 injected systems, stop dosing pump 7 after filling with medicament, open water pump 2, make system's band press operation, carry out matting, move and stop water pump 2 operations after 24 hours, open 11 pairs of system's emptying of wash water valve, open water injection valve 1 simultaneously, replace to system's water filling, when chemically examining from sewage draining exit 12 samplings, water quality can stop displacement with new water is consistent, promptly closes wash water valve 11 and water injection valve 1, and matting finishes.Enter pre-mem stage, open dosing pump 7 the pre-film soup 10 in the water treatment agent storage tank 8 is utilized in dosing pump 7 injected systems, open water pump 2, make system's band press operation after 48 hours, pre-film end-of-job.Stop water pump 2 and open wash water valve 11, make system's emptying, close wash water valve 11, open water injection valve 1, change normal operation over to system's water filling.
Often run into the user and change equipment such as short tube or blind plate 6 in the annual overhaul process, cleaning pre-film work will be undertaken by said procedure, and a system cleans pre-film expense once and do not wait at 120,000～200,000 yuan, decides according to system size.The pipe diameter of finding in the practice at every turn to need in the circulating water system to change is all below 500mm, length never surpasses 800mm, if can put into a container and carry out part and clean pre-film changing short tube or blind plate 6, can save clean pre-film expense and newly water consumption be the technical scheme that needs to be resolved hurrily.
Summary of the invention
The utility model has provided that a kind of circulation cooling water system is local cleans pre-film device, is beneficial to that the user is when changing pipeline and blind plate in the recirculating cooling water system, and the whole pre-film work that must carry out changes the local pre-film that cleans into, reduces the wasting of resources.
For achieving the above object, the technical solution adopted in the utility model provides the pre-film device of a kind of local cleaning of circulation cooling water system, wherein: this device includes the water treatment agent storage tank, cleans pre-film container, be provided with the dosing pump pipe connection between described water treatment agent storage tank and the pre-film container of cleaning, clean the water injection valve that is provided with suitable for reading of pre-film container, bottom one side of cleaning pre-film container is provided with sewage draining exit, cleans will change short tube in the pre-film container or blind plate is vertically put into.
Effect of the present utility model is to use this device, and the used at least 5 tons of pre-film medicaments of cleaning of original whole cleaning are reduced to 25kg, used new water 2500m
3Be reduced to 5m
3, each cleaning charge can reduce more than 100,000 yuan, and this device can be saved the pre-film medicament expense of cleaning and use and new water consumption.Meet the requirement of energy-saving and emission-reduction, and the cleaning prefilming method is provided for other recirculating cooling water system.
