Description
Technical field
The invention belongs to descalling technique field, what relate generally to is a kind of water circulation system apparatus for eliminating sludge.
Background technology
At present, utilize interchanger carry out circulating-heating produce production, domestic water mode very general.Because the water quality in a lot of area is comparatively hard, in the process of circulating-heating hot water preparing, easily occur scale problems in interchanger inside, cause interchanger heat transfer effect to reduce and even block, cause serious damage to equipment, impact is produced.The descaling method taked for incrustation scale problem at present
By adding chemical agent or arranging electronic scale remover in addition to process, although the object of scale removal to a certain degree can be played, but still fundamentally can not solve the problem of fouling, not only increase maintenance and the working cost of equipment, affect heat exchange efficiency, but also the work-ing life of equipment can be reduced.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention proposes a kind of circulation hot-water system apparatus for eliminating sludge, by reducing water hardness, solving the scale problems of equipment, reaching and reducing maintenance of the equipment and working cost, extension device work-ing life, improves the object of heat exchange efficiency.
The present invention realizes the technical scheme that above-mentioned purpose takes: a kind of water circulation system apparatus for eliminating sludge, comprise cyclic water tank and interchanger, circulation line between described cyclic water tank and interchanger is connected with recycle system main line motorized valve and scale removal tank, being connected with master loop pipeline respectively by the pipeline with motorized valve into and out of water end (W.E.) of described scale removal tank, water pump is connected in series with Venturi tube afterwards and cyclic water tank forms a scale removal recycle system, and wherein the low-tension side of Venturi tube is connected with scale removal tank by motorized valve.
Scale removal tank of the present invention is tank structure, and top cover is the detachable round plate of similar blind plate, is welded with rod iron in round plate, rod iron attachment Stainless Steel Wire.
The present invention is connected with the sewage draining exit of tap water water-in and heavy caliber band motorized valve on described scale removal tank.
The present invention is provided with temperature sensor and pressure transmitter in described scale removal tank.
The present invention forms apparatus for eliminating sludge by connecting on the circulation line of circulation hot-water system by scale removal tank, motorized valve, high-lift pump, Venturi tube etc.Recirculated water makes it at the hot water (under 1 normal atmosphere, water temperature just starts sharply fouling after reaching 60 DEG C) becoming about 50 DEG C after interchanger heating 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 DEG C flows into, when liquid level reaches certain liquid level, recycle system motorized valve is opened, apparatus for eliminating sludge motorized valve cuts out, water in cyclic water tank is squeezed in Venturi tube by high-lift pump, utilize the pressure in venturi principle reduction scale removal tank, the reduction of pressure is of value to the condensation of incrustation scale 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, embodiments of the invention are provided as follows:
As shown in Figure 1: the apparatus for eliminating sludge of the circulation hot-water system described in the present embodiment is that the circulation line between cyclic water tank 1 and interchanger 5 is connected with the scaler system be made up of scale removal tank 7, scale removal tank bypass first motorized valve 2, recycle system main line motorized valve 3, scale removal tank bypass second motorized valve 4, high-lift pump 6 and Venturi tube 9.Being connected with master loop pipeline respectively by the pipeline with motorized valve into and out of water end (W.E.) at scale removal tank 7.Namely be connected with scale removal tank bypass second motorized valve 4 at the feed-water end of scale removal tank 7 upper end, be connected with scale removal tank bypass first motorized valve 2 in the water side of scale removal tank 7 lower end.All only there is completely open and close two states in scale removal tank bypass first motorized valve 2, recycle system main line motorized valve 3 and scale removal tank bypass second motorized valve 4.Scale removal tank is the tank body with a constant volume, and top cover is the detachable round plate of similar blind plate, round plate inner face welding steel rod, and rod iron attachment Stainless Steel Wire, can body is cylinder.High-lift pump 6 and Venturi tube 9 are connected in series afterwards and cyclic water tank forms a recycle system, the low-tension side of described Venturi tube is connected with the top of scale removal tank by motorized valve 8, and scale removal tank is also connected with the sewage draining exit of tap water water-in and heavy caliber band motorized valve.Temperature sensor, liquid level sensor and pressure transmitter is also provided with in scale removal tank, liquid level sensor, by sending the liquid level signal in scale removal tank to controlling organization, controls scale removal tank bypass first motorized valve 2 of scale removal tank both sides and opening or closing of scale removal tank bypass second motorized valve 4 by controlling organization.Pressure transmitter, by sending the pressure signal in scale removal tank to controlling organization, is controlled to be positioned at opening or closing of the recycle system main line motorized valve 3 of Venturi tube low-tension side by controlling organization.What controlling organization adopted is all conventional pilot circuit and method, does not repeat them here.During use, temperature sensor water temperature detection is after heating becomes 30 DEG C, recycle system main line motorized valve 3 cuts out, and scale removal tank bypass first motorized valve 2 and scale removal tank bypass second motorized valve 4 of scale removal tank 7 pipeline are opened, and the hot water 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 first motorized valve 2 and scale removal tank bypass second motorized valve 4 are closed, high-lift pump 6 after this action completes, motorized valve 8 is opened, the pressure in scale removal tank 7 is reduced thus by Venturi tube, accelerate the generation (reducing pressure can make the formation of incrustation scale accelerate) of incrustation scale, high-lift pump 6 after one minute, motorized valve 8 cuts out, scale removal tank bypass first motorized valve 2 is opened and is allowed the water in scale removal tank flow in cyclic water tank, when liquid level sensor detects, liquid level is low closes to scale removal tank bypass first motorized valve 2 during set(ting)value, high-lift pump 6 and motorized valve 8 are opened, by Venturi tube, scale removal tank is vacuumized, its internal water molecular pressure caused due to the remaining temperature in scale removal tank 7 and vacuumizing like this reduces, incrustation scale will rapid solidification, when pressure transmitter detection negative pressure is to (water be now attached on steel wire should evaporate) during certain value, close high-lift pump 6 and motorized valve 8, open running water switch, incrustation scale will be cold and different from the coefficient of expansion of steel wire and depart from steel wire with tap water and mix owing to meeting, open blowdown motorized valve after for some time and can discharge incrustation scale.This process of circulation so repeatedly just can be softened water when water temperature does not reach more than 60 DEG C, solves fouling of heat exchangers problem.
