For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, and chemical cleaning (pickling) have caused many problems when cleaning the heat exchanger: the deposits such as scale cannot be completely removed, and the acid solution causes corrosion to the equipment. A loophole is formed, and the residual acid causes secondary corrosion or subscale corrosion of the material, which eventually leads to the replacement of the equipment. In addition, the cleaning waste liquid is toxic and requires a large amount of funds for wastewater treatment. The newly developed non-corrosive cleaning agent for equipment, among which should be a better technology, Fu Shi Tai Ke cleaning agent, which is efficient, environmentally friendly, safe, non-corrosive, not only a good cleaning effect and no corrosion of equipment, can ensure the heat exchanger long-term use. Detergent (specific addition of wetting agent and penetrating agent can effectively remove the most stubborn scale (calcium carbonate), rust, oil scale, slime and other deposits generated in water equipment, and it will not cause harm to the human body. It will not cause corrosion, pitting, oxidation and other harmful reactions to steel, copper, nickel, titanium, rubber, plastic, fiber, glass, ceramic and other materials, which can greatly extend the service life of the equipment.
In the process of industrial production, sometimes unexpected conditions caused by improper operation may cause scale and blockage of individual equipment or local pipeline lines, affecting the normal operation of production. For the situation at this time, it is mainly to quickly remove the dirt to ensure that the production device can operate normally and restore the normal production state. Restore plant productivity. For example, the fouling of chemical equipment causes the heat transfer coefficient of equipment such as heat exchangers to decrease, the flow area of pipelines to decrease or the flow resistance to increase, enabling, consumption of materials, etc. to increase, and production efficiency to decline significantly. At this time, the production efficiency of the production equipment is restored by cleaning and descaling.
For many reasons, heat exchanger equipment, etc. and pipeline lines will produce a lot of dirt such as coking, oil dirt, scale, sediment, corrosion products, polymers, fungi, algae, slime and other dirt. However, the dirt generated during work will cause failure of equipment and pipeline lines, and the equipment system will have production failures, increased energy consumption and material consumption, and other bad conditions. When the dirt is particularly corrosive, it will also interrupt the process and the equipment system will be forced to stop production. Causes various economic losses, and may even cause vicious production accidents. In today's scientific development, it is almost impossible to completely avoid the generation of dirt. Therefore, cleaning of heat exchangers and other equipment has become indispensable in industrial (such as petroleum, chemical, power, and metallurgical industries) production. An important link.
The high-pressure water jet cleaning heat exchanger belongs to the physical cleaning method. Compared with traditional manual, mechanical and chemical cleaning, it has many advantages: low cleaning cost, good cleaning quality, fast cleaning speed, and no environmental pollution. corrosion. China's high-pressure water jet cleaning technology has developed rapidly. The proportion of water jet industrial cleaning in large and medium-sized cities and enterprises is close to 20%, and it is growing at a rate of about 10% per year. It is estimated that in 6-7 years, in China's industrial cleaning industry, high-pressure water jet cleaning technology will occupy an absolute advantage, which is the only way for China's industrial cleaning.
