Abstract
The invention discloses a medicated tank protection preparation for a circulating water system and a using method thereof. The medicated tank protection preparation is formed in a mode that the following preparations are matched according to mass ratio: 600 to 1,000 pieces of prefilming agent, 155 to 195 pieces of prefilming synergist, 180 to 220 pieces of corrosion inhibitor for copper, 80 to 120 pieces of non-oxidizing bactericidal algicide and 80 to 120 pieces of non-oxidizing slime remover. Due to the adoption of the self-prepared medicated tank protection preparation for the circulating water system, which is disclosed by the invention, when the medicated tank protection preparation is added into circulating water, the circulating water system can be ensured not to work and be ensured not to generate serious corrosion under the undrained condition; and the non-drainage corrosion prevention can be adopted, so that the circulating water system can be put into normal operation according to the production requirements and the medicated tank protection preparation has the advantages of saving water, reducing sewage discharge, reducing the production cost and protecting the environment. In the using method of the medicated tank protection preparation, the circulating water added with the tank protection preparation is sealed in a circulating water pipeline under a certain pressure, so that the inside of the pipeline can be prevented from being rusted; and moreover, the and protection preparation can take a good anticorrosion effect.
Description
Technical field
The present invention relates to a kind of dosing that is used for circulating water system and protect jar preparation and method of use thereof, belong to pipeline chemistry field of washing.
Background technology
Matting is to remove hardware surface contaminant or tectum with chemical process, makes its recovery or near a technical skill of original state.The key of chemical cleaning technique is to select suitable chemical for use, comprises sterilization, degreasing degreasing, the floating rust of removal etc.In advance film is after matting finishes, and forms the thin and compact protective film of one deck in the activatory metallic surface rapidly and suppresses carbon steel and the initial corrosion of copper equipment in water, and the low dosage processing is laid a good foundation during simultaneously for next step normal operation.Corrosion inhibiting and descaling agent mainly is meant and can prevents that incrustation scale in the industrial circulating water, dirt from producing, grow and preventing that hardware, pipeline from producing the chemical classes reagent of galvanic corrosion; It is requisite element in the Treatment of Industrial Water; Can be used for prolonging equipment life, and can guarantee the device security production run.Chemical enterprise all will stop production equipment is carried out an overhaul every year, and during overhaul, all will the water in the circulating water system have been arranged, with this corrosion that comes the reduction system to stop transport equipment is caused.While needs clean preparatory film to circulating water system once more after enterprise's overhaul is accomplished, and will need great amount of water resources and produce a large amount of waste water when cleaning each time, preparatory film, and like this without the increase production cost, and environmental pollution is comparatively serious.
Summary of the invention
The technical problem that the present invention will solve is; Providing a kind of can protect environment and practice thrift cost; Guaranteeing that circulating water system is not worked under the situation of not draining does not produce heavy corrosion yet; And can protect jar preparation and method of use thereof according to the dosing that is used for circulating water system of the very fast normal operation input of production needs, can overcome the deficiency of prior art.
Technical scheme of the present invention is: a jar preparation is protected in the dosing that is used for circulating water system, and it is made up of by the mass ratio cooperation following preparation: low-phosphorous prefilming agent 600-1000 part, preparatory film synergistic agent 155-195 part, copper inhibitor 180-220 part, non-oxidizable Biocidal algae-killing agent 80-120 part, non-oxidizable adhesive mud remover 80-120 part.
It is made up of by the mass ratio cooperation following preparation: 800 parts of low-phosphorous prefilming agents, 175 parts of preparatory film synergistic agent, 200 parts of copper inhibitors, 100 parts of non-oxidizable Biocidal algae-killing agents, 100 parts of non-oxidizable adhesive mud removers.
The consumption that the dosing guarantor jar preparation of circulating water system adds in the entry is that low-phosphorous prefilming agent is 800ppm; The film synergistic agent is 175ppm in advance; Copper inhibitor is 200ppm; Non-oxidizable Biocidal algae-killing agent is 100ppm; Non-oxidizable adhesive mud remover is 100ppm;
The method of use that is used for the dosing guarantor jar preparation of circulating water system comprises following process:
The first, open a water circulating pump and carry out the system water circulation;
The second, jar disposable circulating water system that is added to of preparation is protected in the dosing of circulating water system;
The 3rd, water circulating pump was opened 2-3 hour, treated that medicament mixes the back termination of pumping, and closed water circulating pump import and export valve, let the recirculated water band press and was enclosed in the circulating water pipeline.
On the pond of circulating water system, hang with the carbon steel lacing film, be used to monitor corrosion rate.
When the algae deposition was arranged on carbon steel lacing film surface, the pump of opening a circulating water system on every Mondays circulated 2 hours, and the sampling monitoring water quality data; And when each ON cycle water pump, add oxidizing bactericide dioxide peroxide 15 kg～20kg/ ton at every turn.
In step 3, pressure＞0.1Mpa that the densification of recirculated water band is closed.
Compare with prior art; The present invention protects a jar preparation through the dosing of the circulating water system of employing autogamy; Do not produce heavy corrosion with in this dosing keeping preparation input recirculated water circulating water system not being worked under the situation of not draining yet; Because of can taking not draining anticorrosion, so just can have water saving, minimizing sewage discharge, reduce production costs, protect the advantage of environment according to production needs normal operation input very soon.Its method of use adopts its recirculated water band pressure of adding guarantor's jar agent is enclosed in the circulating water pipeline, can prevent like this to get rusty in the pipeline, and good preservative activity is played in this guarantor jar agent capable of using.
With about about the 30000 tons chemical enterprise of year water displacement, but adopt behind the present invention about about 100,000 tons of conserve water resource in every year, practice thrift and clean more than 100,000 yuan of preparatory film medicament buying expenses.The present invention also can let circulating water system reach and open the state of pump driving operation at any time fast, practiced thrift the time, and the acid waste water that also can stop high turbidity, high chroma produces, the protection environment.In a word, compared with prior art, can prolong the work-ing life of equipment, have good economy, society and environmental benefit, and similar chemical project is had reference and directive significance.
