Heat exchanger cleaning agent

Abstract

The invention discloses a heat exchanger cleaning agent. The cleaning agent is characterized in that the component substances of the cleaning agent include, by mass, 5-8 parts of an organic acid, 0.1-0.5 part of a sustained-release agent, 0.5-1 part of a penetrant, 1-3 parts of a dispersing agent, 1-2 parts of a stripping agent, and 0.5-1 part of an active agent, with the balance being water. Thebeneficial effects of the cleaning agent are that the production efficiency of cheese can be enhanced, the expiration date of the cheese can be prolonged, and the convenient production and storage ofthe cheese can be realized; the cleaning agent is non-flammable, non-explosive and non-toxic; the corrosivity of the cleaning agent on equipment and human bodies is small; good descaling and rust removal effects can be realized; the cleaning rate of the cleaning agent for general dirt and rust products is greater than 99%; descaling, rust removal and passivated pre-filming can be integrated; the cleaning time can be shortened for 1 / 2 - 2 / 3; and the cleaning agent can be used under normal temperature, so that convenient usage can be achieved.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a heat exchanger cleaning agent. Background technique [0002] A heat exchanger is a heat exchanger energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid The temperature reaches the index specified in the process to meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . For example, the PTFE heat exchanger for low temperature in power plants is a new device for waste heat recovery in power...

Problems solved by technology

[0003] After the heat exchanger is used for a long time, the surface will adhere to calcium carbonate, barium sulfate, iron oxide and other compounds that are difficult to dissolve and remove, which will affect the use effect of the heat exchanger. The traditional way is to spray a certain amount of inorganic acid cleaning agent on the surface of the equipment for cleaning , and then use a high-pressure water gun to clean the surface. This method is slow, and the cleaning is better than bad, and it is easy to corrode the surface of the equipment and reduce the service life of the equipment.
