Types of cleaning technology
◆When the circulating water system is cleaned with low pH value, the pH value can be controlled between 2.0 and 3.0, and the corrosion rate is far lower than the national standard
◆Single cleaning of melamine reactor and high concentration pickling with 20% nitric acid
◆Off line cleaning technology of low pressure ash water pipeline in coal chemical industry
◆High pressure water jet cleaning technology for single equipment
◆Cleaning technology of chemical equipment with low pH value without shutdown
◆Cleaning technology of decarbonization system
Types of cleaning engineering
The company is a professional company undertaking industrial cleaning engineering earlier in China, which is in a leading position in the industry. Main contract:
◆On line (on-line) and off-line chemical cleaning pre membrane engineering of circulating water system
◆Chemical cleaning and passivation engineering of single equipment (boiler, heat exchanger, tower tank, etc.) and pipeline
◆High pressure water jet cleaning
◆Chemical cleaning of equipment process side
◆Reverse osmosis online cleaning technology, reverse osmosis single membrane off-line cleaning
Using high-efficiency corrosion inhibitor to minimize damage to equipment
Using high-priced metal ion stabilization technology to avoid secondary deposition
The cleaning fluid can reach the discharge standard after simple treatment
The use of low-phosphorus or non-phosphorus pre-film technology greatly reduces the replacement and discharge of water and reduces the impact on the environment
Offline cleaning technology
The reverse osmosis membrane elements with serious pollution need to be treated by off-line cleaning. Off line cleaning refers to the removal of membrane elements from reverse osmosis pressure vessel and loading into special cleaning equipment for cleaning. This cleaning method is easy to operate, clean thoroughly and has good effect. As an effective cleaning method, off-line cleaning, combined with proper cleaning scheme and special cleaning agent, plays an irreplaceable role in the recovery of reverse osmosis membrane performance.
Online cleaning technology
Online cleaning refers to cleaning the entire reverse osmosis device. The membrane element does not need to take out the pressure vessel, and is usually designed and used in larger systems. This cleaning method is simple and convenient to operate, and the time is short. This method can be used when the reverse osmosis membrane pollution is light.
The high-pressure water jet cleaning technology is to achieve the purpose of cleaning through the impact, cavitation, grinding and wedge splitting of the high-pressure water jet on the surface of the object. It has the characteristics of no corrosion to equipment, high cleaning efficiency and energy saving. It has a wide range of applications, not only for cleaning pipes, but also for cleaning industrial equipment (such as heat exchangers, boilers, towers, storage tanks, etc.). It is much faster than manual cleaning. No chemicals are required, and high-cost safety and handling measures are not required at the same time) to make it cleaner and more environmentally friendly.
