Abstract

The utility model provides a chemical cleaning device for closed-loop circulating cooling water. The device comprises a pipeline formed by being sequentially connected with a water inlet valve 1, a water pump 2, a check valve 3, a regulating valve 4, a regulating valve 5, an air cooler 7, a regulating valve 6 and user equipment 8; another pipeline is connected in parallel on the pipeline connected with the regulating valve 5, the air cooler 7 and the regulating valve 6 and is taken a surpassing pipeline 14 for cleaning, which is formed by connecting a stop valve 12 with a stop valve 13 by the pipeline. The chemical cleaning device has the following effects: the air cooler is disconnected by the added surpassing pipeline and the two stop valves so as to carry out primary cleaning, when the cleaning liquid contains a great deal of sewage, impurities, oil contamination and corrosion products, the cleaning liquid is drained and the air cooler is refilled with water so as to carry out secondary cleaning. Then the surpassing pipeline is disconnected so as to lead the cleaning liquid to flow through the air cooler and enter the user equipment to complete the secondary cleaning work, and at the moment, a great amount of impurities in the system are eliminated and can not remain in a finned tube of the air cooler D20, thus improving the cleaning quality.

Description

The chemically-cleaning device of closed cycle cooling water

Technical field

The utility model relates to a kind of cleaning device, particularly has the chemically-cleaning device of the closed cycle cooling water of aerial cooler.

Background technology

Steel-making closed cycle cooling water system will carry out Chemical cleaning before driving, its purpose is exactly the antirust oil that removal equipment and pipeline upper surface scribble, the welding slag in the equipment installation process, silt, dirt.Recirculating cooling water system is after the water flushing simultaneously, and the meeting of carbon steel equipment surface produces floating rust, has only they are handled totally, makes the metal surface cleaning just can finish next step work.

The method that traditional chemical cleans as shown in Figure 1, open water intaking valve 1,, open water pump 2 the water injected system, with the water pump is that power makes water circular flow in system, then from water filling port with the Chemical cleaning medicament from grug feeding jar 10 by dosing pump 11 by water intaking valve 1 injected system of opening.Clean after 24 hours, open blowoff valve 9, the Chemical cleaning medicament is drained.The hidden danger of the method maximum is that dirt, impurity, greasy dirt, the corrosion thing 16 in the subscriber equipment 8 washed in the water by the Chemical cleaning medicament, under in the ribbed pipe 15 of the slow aerial cooler 7 of flow velocity, being detained, cause cooling effect not good, hot-spot, do not reach the expection cleaning performance, more seriously under deposit to ribbed pipe generation corrosion phenomenon, a large amount of corrosion product 16 can stop up the ribbed pipe 15 of aerial cooler 7, will spend every year great amount of manpower and material resources, financial resources to solve this problem.

Summary of the invention

The utility model provides a kind of chemically-cleaning device of closed cycle cooling water, and this system with Impurity removal, has solved the phenomenon that is trapped in the aerial cooler ribbed pipe by adopting secondary cleaning, improves cleaning quality.

For achieving the above object, the technical solution adopted in the utility model provides a kind of chemically-cleaning device of closed cycle cooling water, this device includes the pipeline that is in turn connected to form with water intaking valve 1, water pump 2, check-valves 3, control valve 4, control valve 5, aerial cooler 7, control valve 6, subscriber equipment 8, wherein: with pipeline that described control valve 5, aerial cooler 7, control valve 6 link to each other on a pipeline in parallel for cleaning with surmounting pipeline 14, this cleaning is to be formed by pipeline connection stop valve 13 by stop valve 12 with surmounting pipeline 14.

Effect utilization of the present utility model increases surmounts pipeline and two stop valves and aerial cooler is disconnected carries out cleaning first time, when containing a large amount of dirts, impurity, greasy dirt, corrosion thing in the cleaning fluid, cleaning fluid is drained, and secondary cleaning is carried out in water filling again.This moment, disconnection surmounted pipeline, and cleaning fluid is flow through from aerial cooler, was entering subscriber equipment, finished secondary cleaning work, and at this moment a large amount of impurity in the system are removed, and can not be trapped in the ribbed pipe of aerial cooler D20, have improved cleaning quality.

The specific embodiment

Reaching example in conjunction with the accompanying drawings describes the structure of the chemically-cleaning device of closed cycle cooling water of the present utility model.

The basic thought of the chemically-cleaning device of closed cycle cooling water of the present utility model is in existing closed cycle cooling water pipeline system, increase by one section and surmount pipeline and two stop valves, disconnecting aerial cooler earlier cleans, the cleaning fluid that will have a large amount of floating rust, dirt, impurity is drained, connecting aerial cooler again cleans, original once cleaning is divided into twice carries out, stop subscriber equipment and ducted corrosion thing to enter among the aerial cooler effectively.

As shown in Figure 2, the chemically-cleaning device structure of closed cycle cooling water of the present utility model is, this device includes the pipeline that is in turn connected to form with water intaking valve 1, water pump 2, check-valves 3, control valve 4, control valve 5, aerial cooler 7, control valve 6, subscriber equipment 8, with pipeline that described control valve 5, aerial cooler 7, control valve 6 link to each other on a pipeline in parallel for cleaning with surmounting pipeline 14, this cleaning is to be formed by pipeline connection stop valve 13 by stop valve 12 with surmounting pipeline 14.

The chemically-cleaning device of closed cycle cooling water of the present utility model is achieved in that

The two ends of the aerial cooler 7 in existing closed cycle cooling water pipeline system, just control valve 5, the control valve 6 front and back stop valve 12 that increases in parallel, 13 and clean with surmounting the loop that pipeline 14 is connected to form, when carrying out Chemical cleaning for the first time, open water intaking valve 1, open dosing pump 11 simultaneously, from grug feeding jar 10, extract out the Chemical cleaning medicament in the injected system, close water intaking valve 1 after filling with water and medicament, ON cycle force (forcing) pump 2, make system's band press operation, the water that has the Chemical cleaning medicament passes through check-valves 3 by circulation force (forcing) pump 2, control valve 4, stop valve 12, stop valve 13 and cleaning flow into subscriber equipmenies 8 with surmounting pipeline 14, finish a circulation by pipeline, so circular flow corrosion to the system, dirt, greasy dirt is opened blowoff valve 9 after cleaning, to have corrosion, dirt, the sewer emptying of greasy dirt, aerial cooler is unimpeded when guaranteeing to carry out secondary cleaning.

Close stop valve 12, stop valve 13 then, make to clean to disconnect, open control valve 5, control valve 6, make it to become the complete loops that has aerial cooler 7 with surmounting pipeline 14.At this moment carry out secondary cleaning, open water intaking valve 1, open dosing pump 11 simultaneously, from grug feeding jar 10, extract out the Chemical cleaning medicament in the injected system, close water intaking valve 1 after filling with water and medicament, ON cycle force (forcing) pump 2, make system's band press operation, a large amount of foreign material in service, corrosion, dirt, greasy dirt 16 has been removed, in secondary cleaning, the surface and oil contaminant in the scavenging air cooler can not cause the obstruction of the ribbed pipe 15 of aerial cooler 7, after finishing, cleaning opens blowoff valve 9, secondary cleaning liquid is drained, finish cleaning of the present utility model, the method makes neither dam greasy dirt in the subscriber equipment of the ribbed pipe 15 of aerial cooler 7, corrosion product 16, can clean the ribbed pipe that makes aerial cooler 7 again and expose the metal true qualities, effect is very good.
