INTELLIGENT ULTRASONIC ONLINE ANTI-SCALING AND DESCALING EQUIPMENT
Introductions:
After over ten years of continuous development and practice, now we have been one of the top domestic and international manufacturers in this field and our intelligent ultrasonic descaling devices have been widely used in chemical industry, petrochemical industry, power generation, medical biology, coal coking, industrial boiler and many other situations to solve the scaling problems of various equipment. Our ultrasonic descaling machines can efficiently contain the fouling and clogging problems inside your metal material equipment such as heat exchanger, evaporator, condenser, boiler, oil cooler, primary cooler, pipelines etc., and with just a little power consumption (usually 300 Watts per set) they can keep the scaling equipment at a satisfactory state with our one-to-one customized design solution.
Application Principle:
The intelligent ultrasonic descaling device mainly consists of three parts: host, transducers and adapters. Welding thread adapters are welded perpendicular to the axis of the scaling equipment. The generator in host generates electrical impulses of a given shape. The transducers are connected by a cable to the generator and continuously receive electrical impulses from the generator with carrier frequency at a range of 15 to 30 kHz. These electrical signals are converted by a magnetostrictive core into ultrasonic vibrations of the same frequency. And then continuous ultrasonic vibrations are created in metal and media, which are safe for welding and rolling, but destructive for solid deposits. Ultrasonic pulses of a given shape and parameters do not allow any solid deposits to settle on the surface of scaling equipment, transferring the process of transition of solid dissolved particles to an insoluble form and the process of their precipitation from the surface of scaling equipment.
Problems Your Equipment are Suffering:
The problem of fouling and clogging of chemical petrochemical equipment is a long-term difficult problem that troubles the production of many enterprises. The reduced flow rate and slowing of the flow rate caused by the fouling, crystallization and clogging of the scaling equipment affect the normal operation of the equipment and thus seriously affect production. The harms caused by scaling, crystallization and blockage is mainly reflected in the following aspects:
# Increase labor intensity
# Lead to the equipment to not operate normally
# Reduce product production and quality
# Affect the normal production efficiency
# Reduce the service life of equipment
# Increase equipment safety risk
# Accumulated huge losses due to the harms
Advantages and Disadvantages of Traditional Descaling Methods:
# Pickling or alkaline cleaning can clean the scales and deposits more carefully, but they will bring certain corrosion to the equipment, and the liquid discharge after cleaning will bring secondary pollution to the environment. At the same time, a large amount of water is required for cleaning, resulting in serious water wasting, also the cleaning and shutdown periods are so long.
# Although the mechanical cleaning does not use chemical agents for scaling and plugging, it takes a lot of manpower, material and time to clean up and mostly not thoroughly enough. In most cases the scaling equipment is descaled only when it's scaled and blocked too severely to work normally.
Advantages of Ultrasonic Descaling Device:
# The scaling equipment does not need to stop production to clean the scale, crystallization, and plugging. After the ZNCTXCF series of intelligent ultrasonic anti-scaling devices are put into use, the scaling equipment cleaning cycle will be extended and the equipment downtime will be eliminated, so the system can operate normally. The device is used in an online purely physical method and maintaining the design flow rate and flow rate during operation without stopping production.
# After the parameters of the intelligent ultrasonic anti-scaling and descaling device are adjusted to the optimal value, when the process parameters of the scaling equipment are stable, the scaling equipment cleaning period is extended, the service life of the equipment is increased, and the equipment efficiency and production efficiency of the system are improved.
# As new fouling is avoided, the safety of the scaling equipment is improved, and the service life of the scaling equipment is extended.
# Reduce the cost of cleaning investment, the accompanying pollution and the damages to scaling equipment.
# Reduce the number of scaling equipment cleaning times, reduce the time and labor costs that affect normal production.
# The use of intelligent ultrasonic online descaling device can maximize efficiency of the scaling equipment and realize the design load production.
# Reduce the running resistance of the equipment and reduce the power consumption of the pump.
# The intelligent ultrasonic online anti-scaling device has a long service life and avoids corrosion under scale. After operation, the product promises a warranty period of 1 year, product upgrade priority, and lifetime maintenance.
# With this intelligent ultrasonic anti-scaling and descaling device, you can save operating costs by > 80%, reduce emissions by > 40%, save energy by > 20%, and avoid over-discharge fines. According to this, the enterprise can recover the investment within a short period, thereby benefiting for many years.

Application Effect:-
One of the judgement criteria for the circulation pipeline descaling effect is the delivery capacity. Before the ultrasonic descaling equipment come into use, every 2 months running the circulation pipeline would have generated a 7mm scale layer and as a result surely can't meet the normal production requirement. Our ultrasonic anti-scaling machine went to service at May, 2014, we had open one of the pipelines after 5 months normal operation and found nearly no fouling problem. Below pictures show the scaling status before and after the ultrasonic descaling machine came into use:
