A kind of device of the scale treatment for geothermal air conditioning system
Technical field
The utility model relates to the pipe scale process field, relates in particular to a kind of air-conditioning duct scale treatment equipment, specifically refers to a kind of device of the scale treatment for geothermal air conditioning system.
Background technology
As everyone knows, geothermal space conditioning is directly to extract the underground air conditioner and heat pump unit that is delivered to by the pump housing to carry out exchange heat, the underground water extracted in this process does not pass through purified treatment, be commonly called as hard water, heat exchanger in the central air-conditioning source pump is through work for a long time, and pipe interior easily produces incrustation scale, and pipeline mostly is the U-shaped or type of turning round more, and be positioned at heat exchanger inside, remove very inconvenience.Along with incrustation scale constantly increases, on the one hand the through-flow diameter of pipe interior is diminished, affect water flow, be that pipeline wall thickness increases on the other hand, affect exchange heat.In addition, incrustation scale also has certain corrosivity, corrosion pipeline inside, until pipe perforation, impact is normally used.
At present, the use scale remover that the method for removing incrustation scale has, scale remover becomes faintly acid, water-soluble, can be transported to pipe interior incrustation scale place, after chemical reaction with water, dissolve incrustation scale, remove incrustation scale, although this method is theoretical feasible, while removing incrustation scale, the consumption of scale remover is difficult to hold at every turn, the scale crust thickness of pipe interior stage is difficult to determine, too much interpolation scale remover can cause the waste of scale remover, and very few interpolation scale remover causes descale effect poor, also can produce chemical waste fluid simultaneously; Under physics scale removal mode can just be shaken inner incrustation scale by outside mode of beaing, but can't determine equally whether incrustation scale is removed totally, and outside is beaten pipeline and can be caused pipeline impaired, affect pipeline service life, the secondth, by the equipment dismounting, manual cleaning, although cleaning performance is good, but labour intensity is larger, and downtime is long; The use electromagnetic mode scale removal that prior art also has, but equipment is especially when water temperature is higher, descale effect is poor, and, in order to improve the electromagnetism descale effect, often needs to increase cost to drop into, and operating cost is higher; State-of-the-art descalling technique is ultrasound wave descaling, but the cavitation of ultrasound wave descaling in liquid used is larger in the market, large to equipment and materials harm, affects the service life of pipeline.
Summary of the invention
The technical problems to be solved in the utility model is for the existing weak point of prior art; provide a kind of simple in structure; easy to use, and can effectively reduce the effect of ultrasound wave descaling process cavitation, the device of the scale treatment for geothermal air conditioning system of protection pipeline.
Technical solution of the present utility model is, following a kind of device of the scale treatment for geothermal air conditioning system is provided, comprise: be arranged on the ultrasonic transducer on pipeline, described ultrasonic transducer has probe rod, described probe rod penetrates pipe wall and is positioned at pipe interior, described probe rod length is 3/5 of pipe diameter dimensions length, and described pipeline is provided with pressure-reducing valve.
Adopt above technical scheme,, contribute to the incrustation scale of pipe interior is removed, and cleaning effect is good in pipe interior by ul-trasonic irradiation.When pipe interior produces cavitation, produce suddenly high pressure, can carry out pressure release by pressure-reducing valve, the harm of minimizing to pipeline, probe rod length is 3/5 of pipe diameter dimensions length, can increase the amplitude amplitude, contribute to the incrustation scale in pipeline is removed, suppress the generation of incrustation scale simultaneously.
As preferably, described ultrasonic transducer is no less than two, and the ultrasonic transducer that is no less than two becomes the spiral surrounding shape to be arranged on pipeline.Adopt the technical program, be conducive to be evenly arranged the position of ultrasonic transducer, improve descale effect.
As preferably, the axis of described adjacent ultrasonic transducer is arranged at an angle of 90.Adopt the technical program, can make the omnibearing removing of incrustation scale of circulating line inside, install at 90 ° of angles more simultaneously.
As preferably, between described adjacent two ultrasonic transducers, distance L is 100mm.Adopt the technical program, mainly contain the removing that helps the pipe interior incrustation scale.
As preferably, the frequency of described ultrasonic transducer is 90KHz.Adopt the technical program, mainly improving frequency is a factor that reduces cavitation phenomenon, suitably improves frequency, is conducive to the protection of pipeline, contributes to remove incrustation scale.
As preferably, the amplitude of described ultrasonic transducer is 75 μ m.Adopt the technical program, increase amplitude and contribute to increase ultrasonic intensity, intensity is higher, and cavitation phenomenon is less.
As preferably, between described ultrasonic transducer and pipeline, by screw thread, be connected.Adopt the technical program, is connected reliably between ultrasonic transducer and pipeline.
As preferably, between described ultrasonic transducer and pipeline, be provided with leak-proof device; Described leak-proof device is rubber sheet gasket.Adopt the technical program, can effectively prevent from leaking between ultrasonic transducer and pipeline.
