Technical Field
The invention relates to the technical field of scale cleaning, in particular to a circulating scale cleaning device.
Background
After equipment such as cooler, heat exchanger, radiator run for a long time, incrustation scale can be produced to its equipment cooling tube inner wall, will reduce the sectional area of rivers pipeline, increases hydrologic cycle's resistance, along with the thickening gradually of incrustation scale layer, can block up the pipeline, seriously influences the cooling effect and the heat exchange efficiency of equipment, when the scale deposit face is inhomogeneous, still can arouse local corrosion etc. and influence the life of equipment. Therefore, scale is extremely harmful to the safe operation of the equipment.
The conventional methods for removing scale in the apparatus include two methods: manual descaling and chemical cleaning descaling. The manual descaling mainly adopts mechanical tools such as a steel wire brush and the like, is easy to cause mechanical damage to equipment pipelines, is difficult to clean thoroughly, and has long time consumption and poor effect. The chemical cleaning technology mainly uses cleaning liquid made of strong inorganic acid or strong organic acid with strong corrosiveness, and is connected with equipment to be cleaned through a pipeline by a water pump, a water inlet pipe of the water pump is placed in a water tank containing the cleaning liquid, and a water outlet end of the equipment to be cleaned is placed in the water tank to form a cleaning loop.
The main factors influencing the descaling effect in the cleaning process include: the use temperature of the chemical cleaning agent, the use ratio of the chemical cleaning agent and the cleaning mode using the chemical cleaning agent. (1) The descaling effect of the chemical cleaning agent is most obvious at 40-50 ℃, but the existing chemical scale cleaning equipment does not have a heat source, or the temperature is inaccurately controlled in the cleaning process by using the heat source, so that the descaling effect in the cleaning process can be obviously reduced. (2) The water consumption in the cleaning process is often confirmed through the data of giving on the data plate of treating cleaning equipment to current chemical cleaning equipment, and then confirms and wash the medicament use amount, and the ratio has the cleaner of the corresponding ratio of best cleaning performance, but the actual use amount of water has the error in actual operation, can cause to add and wash the medicament dose too much, causes the waste of cleaner, perhaps washs the medicament dose not enough and causes the cleaning performance unsatisfactory. (3) The existing chemical cleaning equipment usually adopts a continuous circulation washing mode to remove dirt. But the washing mode of intermittent type formula washing earlier and soaking again, the water pump operates a period of time promptly, washes the flush fluid circulation, then stops work with the water pump again, through the soaking of a period of time, can further promote the cleaning performance of incrustation scale, but the operation of water pump is controlled by the power, and the operation of actual operation power supply and outage all needs manual operation, and loaded down with trivial details repetitive work volume is huge.
In addition, the existing scale cleaning equipment adopts the technical scheme that chemical cleaning liquid with corresponding proportion is prepared in an external container in advance, and then the prepared chemical cleaning liquid is added into a solution tank of the cleaning equipment, so that the operation steps are increased, and the workload is increased. In the circulating cleaning process, the peeled scale and impurities can be contained in the chemical cleaning liquid for circulating use, the circulating use effect of the chemical cleaning liquid in the whole circulating cleaning process can be influenced, and certain blockage can be caused to an inlet and an outlet pipeline of the water pump.
