Abstract
Denatonium benzoate (DB) as one kind of bitter agent is added to circular water in boiler heating system, so that circular water has unbearable bitter. This can prevent illegal use of circular water and ensure the safe operation of boiler heating system.
Description
The present invention relates to the new method that prevents that circular water in boiler heating system is stolen, particularly relate to bitters denatonium benzoate (DB) is joined in the circular water in boiler heating system, circular water in boiler heating system is had make us insufferable bitter taste, can prevent fundamentally that circular water in boiler heating system is stolen for its usefulness, guarantee the boiler heating system safe operation.
Bitters DB is the most bitter material that present people have known, and (annotate: ppb is part per billion, 10 to content 10ppb
-9) make the people can feel bitter, content 50ppb makes the people feel bitter, and during 20～30ppm (20～30 gram/ton), its bitter taste just makes us being difficult to stand.
Owing to its low toxicity, environmentally safe, do not influence other performance that is added into material, thereby be applied in many developed countries such as English, U.S., method, days.Britain, France have delivered application patent GB 955,309, the Fr 2,504922 of this compound as Denaturant for ethanol; Increase gradually about this application of compound patent in recent years, as Jap.P. JP 02,127,496 with it as containing pure solid-fuelled bitters, French Patent (FRP) 2,726,832 with it as bitters of refrigerant etc.Incident and the sodium nitrite of generation over the years and the incident of pesticide poisoning of blending fake wine with methyl alcohol and industrial spirit that take place based on China, we have carried out the research of denatonium benzoate as the bitters of the poisonous chemicals of methyl alcohol, agricultural chemicals, germifuge, plant growth regulator, rat poison, sodium nitrite and other people's daily life contact, find that (1～10ppm) denatonium benzoate can make above-mentioned chemicals have bitter taste to denier, can play preventing that people from taking the photograph the purpose of population by mistake, and apply for patent of invention (application number 98101236.1).In China winter, the recirculated water of north city boiler heating system is usually stolen to be his usefulness, brings hidden danger for the normal operation of heating system, has caused enormous economic loss also for warm-air feed department, and having a strong impact on the heating installation normal supply, this has caused ill effect socially.For this reason, heating department takes factory to add methods such as dyestuff, people's urine in the recirculated water of boiler heating system, with as the makeshift that prevents that circular water in boiler heating system is stolen.Although these makeshift can prevent temporarily that circular water in boiler heating system is stolen, yet well-known, industrial dyestuff mostly has carcinogenesis, and that brings therefrom is troubling such as new problem such as environmental pollution, public psychology pressure.In order to address the above problem, we have carried out bitters DB usurps inhibitor as circular water in boiler heating system research.Find that bitters DB has following advantage as the stolen inhibitor of circular water in boiler heating system:
1. usefulness height.The bitters DB people of containing 5 grams in the per ton of boiler heating system recirculated water can feel bitter, contains 20 its bitter tastes of gram and makes us being difficult to stand.Therefore the circular water in boiler heating system that has added bitters just no longer can be as his usefulness, particularly can not be used to do the wash clothing, tableware and have a bath, drink etc.
2. environmentally safe.Document [1.Vet.Human.Toxicol., 33 (6), 545,1991; (2.OECD the Organization for Economic Cooperation and Development) No.302B] report that the toxicity of bitters prawn and fish is very little.An international biodegradation test report is arranged: after 28 days, the biological degradation rate of bitters is 36%.The mutagenesis in vitro test shows that also bitters does not contain the material (Bitrex product information.Macfarlan Smith Ltd., 1989) of inducing mutant organism.
3. can prolong the serviceable life of caliduct.Caliduct mostly is metallic article, and therefore corrosion is the main cause that caliduct damages, and document (GB 955,309) report bitters has erosion-resisting effect to metal.
The solubleness of bitters in water is 5%, directly bitters is joined in the circular water in boiler heating system easily to produce conglomeration and stick on the duct wall, has a strong impact on the usefulness of bitters.We have been by having discovered that two kinds add way preferably, the one: earlier bitters is dissolved in ethanol or the methyl alcohol, makes the ethanol or the methanol solution of bitters, and then this solution is joined in the circular water in boiler heating system; The 2nd: earlier bitters is made saturated bitters aqueous solution, and then this solution is joined in the circular water in boiler heating system.
Embodiment provided by the invention is as follows:
1. 20 gram bitters DB are dissolved in the 80ml ethanol, and then this bitters ethanolic solution is joined in 1～4 ton of circular water in boiler heating system.
2. 30 gram bitters DB are dissolved in the 70ml ethanol, and then this bitters ethanolic solution is joined in 1.5～6 tons of circular water in boiler heating system.
3. 40 gram bitters DB are dissolved in the 60ml ethanol, and then this bitters ethanolic solution is joined in 2～8 tons of circular water in boiler heating system.
4. 20 gram bitters DB are dissolved in the 80ml methyl alcohol, and then this bitters methanol solution is joined in 1～4 ton of circular water in boiler heating system.
5. 30 gram bitters DB are dissolved in the 70ml methyl alcohol, and then this bitters methanol solution is joined in 1.5～6 tons of circular water in boiler heating system.
6. 40 gram bitters DB are dissolved in the 60ml methyl alcohol, and then this bitters methanol solution is joined in 2～8 tons of circular water in boiler heating system
7. 40 gram bitters DB are joined in the water of 200ml, 20～50 ℃ were stirred 1～10 hour, and room temperature is static, and then this bitters saturated aqueous solution is joined in 1～4 ton of circular water in boiler heating system.
Claims (3)
1. new method that prevents that circular water in boiler heating system is stolen, it is characterized in that bitters denatonium benzoate (DB) is joined in the circular water in boiler heating system, the amount that wherein adds bitters (DB) is: 5～20ppm (being the bitters that contains 5～20 grams in the per ton of boiler heating system recirculated water), the method that adds bitters is earlier bitters to be dissolved in ethanol, methyl alcohol or the water, make ethanol, methyl alcohol or the aqueous solution of bitters, and then the solution of making is joined in the circular water in boiler heating system.
2. according to the method for the described adding bitters of claim 1, it is characterized in that in the ethanol or methanol solution of bitters that the content of bitters is 20～40% (w/w).
3. according to the method for the described adding bitters of claim 1, the aqueous solution that it is characterized in that bitters is saturated bitters aqueous solution.
