To process by adding chemical agent or electronic scale remover being set in addition, although can to a certain degree play the object of scale removal, but still can not fundamentally solve the problem of fouling, maintenance and the working cost of equipment have not only been increased, affect heat exchange efficiency, but also can reduce the work-ing life of equipment.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of circulation hot-water system apparatus for eliminating sludge, by reducing water hardness, the scale problems of solution equipment, reach and reduce maintenance of the equipment and working cost, extension device work-ing life, improve the object of heat exchange efficiency.
The utility model is realized the technical scheme that above-mentioned purpose takes: a kind of water circulation system apparatus for eliminating sludge, comprise cyclic water tank and interchanger, on the circulation line between described cyclic water tank and interchanger, be connected with recycle system main line motorized valve and scale removal tank, being connected with master loop pipeline by the pipeline with motorized valve respectively into and out of water end (W.E.) of described scale removal tank, water pump is connected in series a rear and scale removal recycle system of cyclic water tank composition with Venturi tube, wherein the low-tension side of Venturi tube is connected with scale removal tank by motorized valve.
Scale removal tank described in the utility model is tank structure, and the detachable round plate that top cover is similar blind plate, is welded with rod iron in round plate, and rod iron adheres to Stainless Steel Wire.
The utility model is connected with the sewage draining exit of tap water water-in and heavy caliber band motorized valve on described scale removal tank.
The utility model is provided with temperature sensor and pressure transmitter in described scale removal tank.
The present invention by connecting and form apparatus for eliminating sludge by scale removal tank, motorized valve, high-lift pump, Venturi tube etc. on the circulation line of circulation hot-water system.Recirculated water makes it after interchanger heating, become the hot water (under 1 normal atmosphere, water temperature just starts sharply fouling after reaching 60 ℃) of 50 ℃ of left and right by adjust flux, now the motorized valve of the recycle system cuts out, the motorized valve of apparatus for eliminating sludge is opened, the water of 50 ℃ flows into, when liquid level reaches certain liquid level, recycle system motorized valve is opened, apparatus for eliminating sludge motorized valve cuts out, high-lift pump is squeezed into the water in cyclic water tank in Venturi tube, utilize venturi principle to reduce the pressure in scale removal tank, the reduction of pressure is of value to incrustation scale condensing in scale removal tank, thus, effectively reduce water hardness, the scale problems of solution equipment, reach and reduce maintenance of the equipment and working cost, extension device work-ing life, improve the object of heat exchange efficiency.

Embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1: the apparatus for eliminating sludge of the circulation hot-water system described in the present embodiment is on the circulation line between cyclic water tank 1 and interchanger 5, to be connected with the scaler system being comprised of scale removal tank 7, scale removal tank bypass the first motorized valve 2, recycle system main line motorized valve 3, scale removal tank bypass the second motorized valve 4, high-lift pump 6 and Venturi tube 9.In being connected with master loop pipeline by the pipeline with motorized valve respectively into and out of water end (W.E.) of scale removal tank 7.The feed-water end in scale removal tank 7 upper ends is connected with scale removal tank bypass the second motorized valve 4, is connected with scale removal tank bypass the first motorized valve 2 in the water side of scale removal tank 7 lower ends.All only there is completely open and close two states in scale removal tank bypass the first motorized valve 2, recycle system main line motorized valve 3 and scale removal tank bypass the second motorized valve 4.Scale removal tank is the tank body with a constant volume, the detachable round plate that top cover is similar blind plate, and round plate inner face welding steel rod, rod iron adheres to Stainless Steel Wire, and can body is cylinder.High-lift pump 6 is connected in series a rear and recycle system of cyclic water tank composition with Venturi tube 9, the low-tension side of described Venturi tube is connected with the top of scale removal tank by motorized valve 8, is also connected with the sewage draining exit of tap water water-in and heavy caliber band motorized valve on scale removal tank.In scale removal tank, be also provided with temperature sensor, liquid level sensor and pressure transmitter, liquid level sensor, by sending the liquid level signal in scale removal tank to controlling organization, is controlled scale removal tank bypass first motorized valve 2 of scale removal tank both sides and opening or closing of scale removal tank bypass the second motorized valve 4 by controlling organization.Pressure transmitter is by sending the pressure signal in scale removal tank to controlling organization, controlled the opening or closing of recycle system main line motorized valve 3 that is positioned at Venturi tube low-tension side by controlling organization.What controlling organization adopted is all conventional pilot circuit and methods, does not repeat them here.During use, temperature sensor water temperature detection becomes after 30 ℃ through heating, recycle system main line motorized valve 3 cuts out, and scale removal tank bypass the first motorized valve 2 and scale removal tank bypass second motorized valve 4 of scale removal tank 7 pipelines are opened, and the hot water being heated flows into scale removal tank 7 by interchanger 5.When the liquid level in scale removal tank 7 reaches set-point, recycle system main line motorized valve 3 is opened, scale removal tank bypass the first motorized valve 2 and scale removal tank bypass the second motorized valve 4 are closed, after this action completes, high-lift pump 6, motorized valve 8 is opened, by Venturi tube, reduce the pressure in scale removal tank 7 thus, accelerate the generation (reducing pressure can make the formation of incrustation scale accelerate) of incrustation scale, after one minute, high-lift pump 6, motorized valve 8 cuts out, scale removal tank bypass the first motorized valve 2 is opened the water allowing in scale removal tank and is flowed in cyclic water tank, when liquid level sensor detect liquid level low during to set(ting)value scale removal tank bypass the first motorized valve 2 close, high-lift pump 6 and motorized valve 8 are opened, by Venturi tube, scale removal tank is vacuumized, like this due to the remaining temperature in scale removal tank 7 and vacuumize its internal water molecule pressure causing and reduce, incrustation scale will solidify rapidly, when pressure transmitter is surveyed negative pressure to certain value (water being now attached on steel wire should evaporate), close high-lift pump 6 and motorized valve 8, open running water switch, incrustation scale will be owing to meeting cold and mixing with tap water from the different steel wires that depart from of the coefficient of expansion of steel wire, after for some time, open blowdown motorized valve and can discharge incrustation scale.This process of circulation so repeatedly just can not softened water when water temperature reaches more than 60 ℃, has solved fouling of heat exchangers problem.
