Abstract
The invention discloses a heat exchanger detergent which is compounded from the following components in parts by mass: 0.01-0.02 part of tetrahydrofuran, 5-7 parts of sulfamic acid, 2-4 parts of maleic anhydride, 8-11 parts of citric acid, 0.05-0.1 part of thiocarbamide, 1-2 parts of EDTA (ethylene diamine tetraacetic acid) and the balance of water. The heat exchanger detergent can quickly eliminate and dissolve various water scales, rusty scales and other deposits in various heat exchangers, and can form a protective film on the metal surface to prevent the metal corrosion and water scales from quick formation. The heat exchanger detergent has excellent eliminating effects on cement films, dirty bacterium algae and etch pits on the surfaces of various devices and sanitary facilities.
Description
Technical field
The invention belongs to chemical field, specifically relate to a kind of interchanger clean-out system.
Background technology
By the impact of Traditional Thinking idea and the factor such as cleaning technique scarcity of resources and disappearance, the impact of most enterprises and individual heat exchanger fouling and remove technique and also rest on traditional " destructiveness " technique and the idea aspects such as machinery, high pressure water, chemical pickling; And think that equipment washing only just can be considered when having a strong impact on production simply, what it did not know incrustation scale is created on the energy consumption constantly affecting enterprise, engulfs the profit of enterprise.And the single expense in order to reduce cleaning, have selected purging method equipment being had to infringement and corrosion, the stagnation causing interchanger seepage even to scrap and produce, has paid than clean-out system high the hundred times even cost of thousands of times.
Current each state is all developing Environment protection cleaning technology with all strength, and in the hope of reducing energy consumption, choke suppress is to the excess destruction of environment.In developed country, each scientific research institution especially focuses on the research and development of green technology, and China is also progressively being drawn close to environment-friendly cleaning agent new technology at present.
Summary of the invention
The present invention relates to a kind of interchanger clean-out system, it can remove the incrustation scale, rust deposite and other settling that dissolve in various heat-exchange equipment fast, meanwhile, forms protective membrane, prevent the quick formation of metallic corrosion and incrustation scale in metallic surface; To the cement thin layer on various equipment and sanitary facility surface, dirt bacterium algae, plaque have splendid scavenging(action).
Interchanger clean-out system of the present invention is made up of following formula and the cooperation of quality component forms: tetrahydrofuran (THF) 0.01 ~ 0.02 part, thionamic acid 5 ~ 7 parts, maleic anhydride 2 ~ 4 parts, citric acid 8 ~ 11 parts, thiocarbamide 0.05 ~ 0.1 part, EDTA1 ~ 2 part, surplus is water.
A kind of manner of formulation of interchanger clean-out system is: the tetrahydrofuran (THF) of aforementioned proportion, thionamic acid, maleic anhydride, citric acid, thiocarbamide, EDTA are joined in a certain amount of water, stir and can obtain this interchanger clean-out system.
