Description
Technical field
The utility model relates to the heat exchanger wash machine, specifically a kind of portable heat exchanger cleaning device that is mainly used in the scavenge pipe shell heat exchanger.
Background technology
At present, known heat exchanger divides many types, such as spray-type heat exchanger, double pipe heat exchanger, plate type heat exchanger, shell-and-tube heat exchanger etc., but because heat exchanger long-time running, be used for cooling off or the difference of the pure degree of heated side and the difference of the character of processing medium own cause fouling of heat exchangers to become inevitable, while is because of the difference of design feature of heat exchanger own and specifications and models, cause the fouling degree also different, the cross section, inner passage is diminished even stop up, cause the heat exchanger heat exchange efficiency to reduce, thus the safety of normally carrying out of producing of influence and equipment.Therefore, heat exchanger should regularly clean, and removes dirt, to guarantee the high efficient heat exchanging of heat exchanger and normally carrying out of production.Under the situation of, complicated component serious in fouling, general common physical method is easy cleaning not, and the process of unpicking and washing wastes time and energy.
According to the difference of cleaning method, main cleaning method is that physics cleans and Chemical cleaning.Utilize mechanics, acoustics, optics, the principle of electricity, calorifics relies on the effect of external energy, as mechanical friction, and ultrasonic wave, negative pressure, impacting with high pressure, ultraviolet ray, steam etc. are removed the method for body surface dirt and are cleaned physics; Rely on the effect of chemical reaction, the method for utilizing chemicals or other solvent cleaning body surface dirt is Chemical cleaning.As removing rusty stain, the incrustation scale of body surface with various inorganic or organic acids, remove the color spot of body surface with oxidant, with bactericide, disinfectant killing microorganisms and remove mildew etc.Physics cleaning and Chemical cleaning all exist pluses and minuses separately, have good complementarity again.In actual application, all be that both are combined use usually, to obtain better cleaning performance.
No matter utilizing what method cleans, must need a kind of special cleaning device to finish this work, but instrument that cleaning used or instrument all do not have forming a whole of system, be unfavorable for improving the efficient of cleaning, when particularly needing online portable washing and cleaning operation, have too many difficulties to cope with especially, the on-line cleaning locomotive that has a kind of double pipe heat exchanger in the but present prior art, its disclosure is, utilize centrifugal type slurry pump to the liquid work done, increase the pressure energy and the speed energy of cleaning liquid, make it satisfy the energy requirement of Fouling Cleaning; The instrumentation groove is mainly used to measure circular flow, reclaims the fluidized solids particle, measures the speed of adding pellet, the solid concentration in the control cleaning fluid; The main function of fluid-bed is the homogeneous fluidization that guarantees solid particle, prevents that thick particle from entering annular space between the pipe of double pipe heat exchanger and the accident that results in blockage, and the pump groove of double as centrifugal pump; By-pass valve adjustable throttle between pump discharge and the fluid-bed is through the energy and the pressure head of water-cooled organ pipe interstitial fluid body, to improve the operating flexibility of this device.Instrumentation groove, fluid-bed and centrifugal pump are installed on the underframe that has three wheels, form the cleaning Vehicle of a conveniently moving.
