In this case, the working water circulating path launching water pump P is:
Water intaking path is, from the oral siphon end 21 of heat exchange pipeline section 20, flows through the first water intaking path of the transmitting water pump P that the first arm 51 and the second arm 52 are formed; The backwater path of launching water pump P is flow through little ball collector 32 in the 3rd arm 43, way of valve B3, the 3rd arm 63, first three-way pipe 40, and service pipe (the first arm 41) forms the first backwater path; So, launch water pump P effect through pipe and form high-voltage high-speed current, the rotating wash bowl in little ball collector 32 is driven to spray into oral siphon end 21 with the spontaneous bulb 41 of high speed, and be the initial velocity setting in motion of an angle with the tube wall of this heat exchange pipeline section 20, the current sprayed at a high speed produce turbulent phenomenon simultaneously in heat exchange pipeline section 20, greatly promote the probability of cleaning bead high-speed impact heat exchange pipeline section 20 internal face, incrustation scale is fast and effeciently washed away and smashes, promote scale removal efficiency.
Cleaning bead after c, transmitting enters in cooling system heat exchanging pipe and cleans internal dirt under the drive of pipeline water flow.
D, repetition aforesaid operations.
Be not difficult to find out by said process, launch in physics scale removal 30 in above-described embodiment between water pump P and this heat exchange pipeline section 20 is extract water route and backwater Path Connection with two, when described transmitting water pump P is with first set water intaking path and the work of backwater path, the backwater of this transmitting water pump P flows through described little ball collector and service pipe; When described transmitting water pump P, when extracting water route and the work of water outlet path with second, catches ball device and little ball collector described in the water intaking of this transmitting water pump P flows through; And described transmitting water pump P respectively with first set, second extract water route and backwater path work time, the water (flow) direction flowing through this little ball collector is contrary.Wherein first set water intaking path and backwater path and second are extracted in water route and backwater path, the pipeline of its partial sector may be overlapping (namely both first set water intaking bear pipeline effect in backwater path, also in the second cover water intaking backwater path, pipeline effect is born), but because the keying of valve is different, make water (flow) direction completely contrary.Therefore described physics apparatus for eliminating sludge 30, by launching the different operating path of water pump P, can play the effect of quick collection cleaning bead and transmitted at high speed cleaning bead.
Wherein clean bead not illustrate in the drawings, it is generally in chondritic, and its surface has some burrs.Such as can adopt the core that density is larger, make at the shell of outer wrap one deck abrasive rubber, form some burrs in case surface.Abrasive rubber, its frictional force is large, and scale removal power is strong, and recycling rate of waterused is high, and can not injure comparatively hard inner-walls of duct when scale removal; Or described bead is the chondritic that steel wire winding is formed.Wherein little ball collector 32 can be sieve-like or basket storing apparatus, can collect described cleaning bead, but does not affect current and dirt disintegrating slag passes through.Wherein, described in catch ball device 31 and can be existing any structure, also can be sieve-like or basket funnel-shaped structure, cleaning bead can be caught and by the opening of bottom, cleaning bead is collected in little ball collector 32.Described transmitting water pump P is the pump that can produce high-voltage high-speed current.Consider that system of the present invention mainly uses in colliery simultaneously, need to realize explosion-proof, therefore described controller 70 can be anti-explosion electric Ore-controlling Role.Wherein, each manually-operated gate C1-C6 conveniently keeps in repair and arranges, also can not arrange or magnitude setting is not limited in the present embodiment one.
The above; be only the representational detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
