Firstly, remove the plate according to the disassembly method of the heat exchanger manufacturer. Use a brush or soft cloth to rinse the loose dirt on the plate with clean water as much as possible (to reduce the consumption of detergent), and then soak the plate in a plastic container containing detergent (remove the sealing gasket on the plate). Soak for no less than half an hour (referring to the detergent used). Detergents may decrease their concentration and work efficiency due to an increase in soaking times. In this case, the soaking time can be appropriately extended or the detergent can be increased or replaced. The control of soaking time is generally observed with the naked eye. When the dark black dirt on the original plate has gradually turned yellow, it indicates that the dirt has dissolved and cleaning can begin. When cleaning, use a brush or soft cloth to brush and rinse the edges until the dirt is completely removed. If there is still residual dirt that has not been dissolved, it can be soaked again, and the board can be washed clean and dried. Solids aggregate on the inner surface of the fine mesh, forming a filter cake that filters out even finer particles, creating a pressure difference. Once the pressure drop reaches the preset level, a cleaning cycle is activated by the control system by opening the cleaning valve (4) at the atmospheric discharge point and closing the optional control outlet valve.

Heat exchanger cleaning agent belongs to the category of safe and environmentally friendly strong cleaning and descaling agents. It is composed of various active agents, acid salts, organic acids, penetrating agents and other components, and can quickly dissolve scale, rust and other deposits in various heat exchange equipment. At the same time, it forms a protective film on the metal surface to prevent metal corrosion and rapid formation of scale; It has an effect on the thin layer of cement, dirt, bacteria, algae, and corrosion spots on the surfaces of various equipment and sanitary facilities.

(3) Improve production capacity and enhance product quality. The pollutants on the surface of raw materials can achieve the goal of maintaining their good post-processing performance and improving product quality. Regular cleaning of equipment can maintain its production capacity and reduce the impact of dirt on product performance. Acid washing: Soak the heat exchanger filled with acid solution in a static state for 2 hours. Then continuously cycle it dynamically for 3-4 hours. During this period, clean it alternately in both positive and negative directions every 0.5 hours. After pickling, the pickling solution should be diluted and neutralized before being discharged.

1. Chemical cleaning process: water rinse, acid wash, descaling, water rinse, passivation treatment;

2. Disconnect other systems unrelated to the cooling coil and connect the cleaning tank, cleaning pump, and cooling coil into a closed cleaning circuit;

3. Check the leakage of the cleaning system under simulated cleaning conditions, and at the same time, check for loose dirt inside the coil. When there are no large particles or impurities present in the flushing water at the outlet, the water flushing is completed;

4. After the water flushing is completed, circulate the "heat exchanger cleaning agent" in the cleaning tank, control the concentration of the main cleaning agent at 3-6%, and maintain the temperature within the range of 50-60 ℃. Perform cyclic cleaning and decontamination in the system for about 23 hours. Regularly measure the pH value of the acid solution using pH test strips (once every 20 minutes), keeping it below 1. When the pH value stabilizes within half an hour and there is no gas released from the cleaning system, the acid washing process is terminated;

5. After passing the water rinse, circulate and add "passivation pre film agent" for passivation treatment to improve the corrosion resistance of copper pipes. After the concentration of the entire system solution is evenly mixed, stop circulating and soak for 2-3 hours. Drain the passivation solution from the system, then neutralize it with a "neutralizing treatment agent" and discharge it (pH 6-7). The cleaning process is complete.

Manufacturer of heat exchanger cleaning agent for processingThe company's philosophy is based on the principle of putting customers first. *Our services, advanced corporate philosophy, compatible business platform, brand new product quality and advanced technology team, scientific management and rigorous work style. Give back to society. Note: Due to the material characteristics of ceramic heat exchangers, passivation treatment is not required. Simply dilute and rinse with water with a little cleaning agent.

Due to the influence of traditional thinking concepts and the scarcity and lack of cleaning technology resources, most enterprises and individuals still rely on traditional "destructive" processes and concepts such as machinery, high-pressure water, and chemical acid washing to prevent scaling of heat exchangers; And it is simply believed that equipment cleaning is only considered when it seriously affects production, without realizing that the generation of scale is constantly affecting the energy consumption of enterprises and devouring their profits. Moreover, in order to reduce the cost of cleaning, a cleaning method that causes damage and corrosion to the equipment was chosen, resulting in leakage or even scrapping of the heat exchanger and production stagnation, which cost hundreds or even thousands of times more than cleaning agents.

At present, countries are making every effort to develop environmentally friendly cleaning technologies in order to reduce energy consumption and curb excessive damage to the environment. In developed countries, various scientific research institutions pay special attention to the research and development of environmental protection technologies. In the past two years, high-tech enterprises have successively launched related new technologies, which have attracted attention. Currently, China is gradually approaching new technologies for environmental cleaning agents.
