Description

A kind of heat exchanger cleaning agent
Technical field
The present invention relates to technical field of chemical products, more particularly to a kind of heat exchanger cleaning agent.
Background technique
Heat exchanger is that changing for heat transfer between material is realized between a kind of fluid at two or more different temperatures Hot device energy-saving equipment is that heat is made to pass to the lower fluid of temperature by the higher fluid of temperature, fluid temperature (F.T.) is made to reach process Set quota to meet the needs of process conditions, while being also one of the capital equipment for improving energy utilization rate.Heat exchanger exists It is occupied an important position in chemical industry, petroleum, power, food and other many industrial productions, heat exchanger can be made in Chemical Manufacture For heater, cooler, condenser, evaporator and reboiler etc., it is widely used.Such as power plant's low temperature is exchanged heat with polytetrafluoroethylene (PTFE) Device is that power plant is the new device equipment for reducing exhaust gas temperature and carrying out waste heat recycling.
Heat exchanger is difficult to dissolve the chemical combination of removing using rear surface meeting adhesion calcium carbonate, barium sulfate, iron oxide etc. for a long time Object, influences the using effect of heat exchanger, and traditional mode is to spray a certain amount of inorganic acid scavenger in equipment surface to carry out clearly It washes, removing surface is then carried out using giant, this mode speed is slow, and cleaning is better than bad and easy to equipment list Face generates corrosion, reduces the service life of equipment.
Summary of the invention
The object of the invention is that providing a kind of heat exchanger cleaning agent to solve the above-mentioned problems.
The present invention through the following technical solutions to achieve the above objectives:
A kind of heat exchanger cleaning agent, each component substance and its mass fraction are as follows: 5-8 parts of organic acid, sustained release agent 0.1-0.5 Part, 0.5-1 parts of bleeding agent, 1-3 parts of dispersing agent, 1-2 parts of remover, 0.5-1 parts of activating agent, surplus is water.
In the present embodiment, any one of the organic acid in hydroxyacetic acid or 1-hydroxy ethylidene-1,1-diphosphonic acid.
In the present embodiment, the corrosion inhibiter is selected from phosphonic acids (salt), phosphine carboxylic acid, coloured glaze base benzothiazole, benzotriazole, sulfonation wood Quality is one such or two kinds.
In the present embodiment, any one of the remover in mineral oil, organosilicon, polyethers.
In the present embodiment, the bleeding agent be selected from fast penetrant T, alkali-resistant penetrant OEP-70, alkali-resistant penetrant AEP, Seeping at high temperature agent JFC-M is one such or two kinds.
In the present embodiment, the dispersing agent is selected from peregal 0-8, peregal 0-9, peregal 0-10, peregal 0-15, puts down Any two kinds in flat plus 0-20, peregal 0-30, and two kinds of component ratio is 1: 1.
In the present embodiment, the activating agent is by being mixed into secondary alkyl sulfonate, alkene based on sodium n-alkylbenzenesulfonate salt Sulfonate, alcohol sulfate, sulfo fatty acid ester salt, aliphatic acid polyethenoxy ether sulfate are one such or two kinds are made, The component of middle sodium n-alkylbenzenesulfonate salt is not less than 95%.
In the present embodiment, appearance of the invention is white clear liquid, non-ignitable, not quick-fried, nontoxic and pollution-free.
The beneficial effects of the present invention are: non-ignitable, not quick-fried, nontoxic, scale removal, derusting effect small to equipment and personal corrosivity Fruit is good, cleans rate to general dirt and rust deposite product and is greater than 99%, scale removal, derusting, passivation film three unifications, when shortening cleaning Between 1/2-2/3, can be used under room temperature, it is easy to use.
Specific embodiment
Technical solution of the present invention is purged below, is fully described by, it is clear that described embodiment is only this hair Bright a part of the embodiment, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
