Abstract
The invention relates to a method for cleaning the dirt of solar-energy water heater, which comprises: filling the dirt cleaner into container and connecting the outlet of container to the water inlettube of water heater; pressurizing the container and turning on its valve to feed the dirt cleaner into said water heater and filling water into it to 1/5-3/5, to wash the water heater for 1-2 hours;and turning on the water outlet tube to discharge the washing water liquid; then turning on the water inlet tube to wash the water heater via clear water until the pH valve of discharged water is neutral. The invention can overcome the defects of present method that needing climbing up roof, with simple process and lower cost.
Description
One, technical field
The present invention relates to a kind of scale removal cleaning method, specifically relate to a kind of method of removing dirt of solar energy water heater.
Two, background technology
Solar water heater especially vacuum pipe solar water heater has entered many families, and it is safe in utilization, convenient, and energy-conservation.Yet in the use of solar energy, fouling and incrustation are unavoidable problem, especially a solar vacuum-tube water heater, and incrusted deposit is on the inwall of vacuum tube; And because the inclination of vacuum tube is placed, the incrustation scale that comes off from the vacuum tube inwall can be deposited in the vacuum tube, to such an extent as to can't discharge cumulative, long-pending at last full whole vacuum tube.The direct result that solar energy fouling and incrustation bring is exactly the decline of solar heat efficient, and in the incrustation scale serious area, people have to climb roof every year, take solar water heater apart cleaning, and the incrustation that has is serious even will change vacuum tube.
Water softening can be addressed this problem, yet for average family, the expense of demineralized water is difficult to bear.People also wish to reach by the structure of adjusting water heater the purpose of scale removal.Though yet do like this can be to a certain degree head it off, shortcoming is as follows: the first, for the water heater that has adopted no descaling function and the user that the thermal efficiency descends occurred, the method is powerless; The second, some incrustation scale is to be combined in the vacuum tube inwall closely, and vacuum tube is owing to being that glass structure bears incessantly rapping, so the situation of incrustation still can occur; The 3rd, the incrustation scale that is not deposited on the vacuum tube inwall can be flushed on people's the health with current when people have a bath, bring very offending granular sensation, if the long-pending piece of incrustation scale is excessive, if make the people of water offhand, also face the danger that is scratched, so people wish that still incrustation scale can temporarily rest in the water heater, or, increased cost undoubtedly and set up proprietary passage by proprietary passage discharge.
Using contaminant removing cleaning agent that solar water heater is implemented regular cleaning can address these problems.Occurred several solar water heater cleaning agents in the market, yet problem is that people are difficult to these cleaning agents are delivered in the solar water heater.Especially for the solar water heater that is placed on the roof equal-height position, people are difficult to just can easily clean them at home.
Three, summary of the invention
The object of the present invention is to provide a kind of can easily be in the indoor solar water heater that is delivered to outdoor roof, roof eminence with the liquid scale remover, the method that dirt is cleaned.
The objective of the invention is to be achieved through the following technical solutions:
A kind of method of removing dirt of solar energy water heater the steps include:
(1) scale remover is contained in the container, outlet of container is connected with the water inlet pipe (or overflow pipe) of solar water heater;
(2) in container, increase air pressure with propellant (fluorine Lyons or compressed air) or manual pressure device, make container inner pressure reach 1-3MPa;
(3) openable container valve, scale remover under pressure, just be transported in the solar water heater on roof, open the 1/5-3/5 of water inlet pipe supplementing water to the solar water heater capacity, just water heater being carried out chemical cleaning cleans, clean after 1-2 hour, open the valve of heater discharge pipe, the waste liquid that cleans is entered downcomer;
(4) open water inlet tube of water heater and clean with clear water that to reach pH value until the water of discharging for several times be neutral.
Above-mentioned container is metal can or plastic tank.
Above-mentioned scale remover is a kind of aqueous solution that contains acid, corrosion inhibiter, surfactant, and wherein Suan content is 30%-80%, and sustained release agent content is 1%-5%, and surface-active contents is 1%-5%, and all the other are the content of water.
Above-mentioned acid is a kind of in hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, sulfamic acid, acetic acid, citric acid, EDTA, HEDP, the glycolic acid.
Above-mentioned corrosion inhibiter is a kind of in hexamethylenetetramine, two adjacent benzoic acid ureas, tetramethyl pyridine, imidazoles quaternary amine sodium, the sodium lignin sulfonate.
Above-mentioned surfactant is a kind of in neopelex, lauryl sodium sulfate, AEO, APES, the soil temperature (series).
The container of dress usefulness scale remover in use, and the pipeline (water inlet pipe or overflow pipe) that container outlet links to each other with solar water heater is continuous, for preventing to come off, can adopt to be threaded.After the pressurization, the valve of openable container, scale remover just are transported in the solar water heater on roof in container, solar water heater is carried out chemical cleaning clean.
The waste liquid that cleans can not re-use, and it be entered sewer.And with clean running water solar water heater is cleaned repeatedly until acid and to be cleaned fully, water pH value to be discharged reaches till the neutrality.
The present invention has overcome present needs and has climbed the shortcoming of removing to remove dirt in the solar water heater on the roof, realized being transported in the solar water heater indoor just scale remover can easily being pressed into, and the dirt of water heater removed, this descaling method is simple, economical and practical.
