In chemical production, there are often a large number of storage tank equipment, which must be cleaned to varying degrees before or during operation due to the requirements of operating process conditions. In the chemical industry, the cleanliness of tanks will directly affect the quality of finished products, so tank cleaning nozzle is a very important process.
Tank cleaning can be divided into two ways: manual and automatic. Cleaning can refer to simply rinsing with water, or cleaning with cleaning agents and chemicals, or it can refer to sanitizing with cleaning agents that reduce contamination caused by bacteria. Either way, the ultimate goal of tank cleaning is to bring the tank to a suitable standard for the application through rinsing, cleaning or periodic disinfection, maximizing the removal of contamination that alters the safety, identity, strength, quality and purity of the finished product thing.
There are many cleaning methods that can be used for tanks, but the most common is the full cycle, immersion chemical cleaning method. These methods all have certain limitations and are difficult to be widely used.
Comparison of advantages and disadvantages of several commonly used cleaning methods
1. Filled chemical cleaning method
Advantages: In this way, when fully emptying, the dead corners in the entire tank and tank can be removed, the contact time between the cleaning liquid and the scale is long, the reaction is sufficient and thorough, and a good cleaning effect can be achieved.
Disadvantages: It needs to consume a lot of chemical cleaning agents, and the flow rate of the cleaning solution is low, the cost is high, and the time is long. Especially when cleaning equipment with large volume, the applicability is limited. In addition, after the cleaning is completed, a large amount of waste liquid is treated, which brings great difficulties to cleaning.
2. High pressure three-dimensional water jet cleaning method
Advantages: The three-dimensional space nozzle can be used to spray and clean the inner wall of the container. The required medium can be water or cleaning agent, and the required amount of the medium is small. Under the action of chemical action and impact force, the scale can be removed. It has better cleaning effect on insoluble scale and scale with strong adhesion.
Disadvantages: The medium can only be cleaned at room temperature, the heating is difficult, and the temperature range is limited; the one-time purchase cost of equipment and other equipment is too high, and the general manufacturer cannot afford it; the operation process is more complicated and the safety is slightly poor; for The removal of large-scale rust is feasible, but it is easy to generate secondary rust; the cleaning of large-volume equipment and slender-shaped equipment is relatively limited.
3. Spray cleaning method
Advantages: (1) Simple processing. Mainly for the processing of spray rings and distributors; (2) The cleaning medium can be heated according to the cleaning conditions; (3) The cleaning equipment is simple and the investment is small; (4) During the cleaning process, the cleaning medium has a large flow rate , easy to remove scales; (5) widely used for cleaning of scales that are easy to react or dissolve with the medium; (6) the amount of cleaning medium is very small, and the economy is very high; (7) the operation is simple and the safety is high; ( 8) It can be used to clean the inner and outer surfaces of large containers (tanks, tanks).
Disadvantages: (1) It is difficult to clean insoluble scales because other external forces are not used in the process; (2) It is difficult to clean equipment with irregular shapes.
Automated tank cleaning technology
The methods described above can all be classified into chemical cleaning/manual cleaning. There are many professional cleaning companies on the market. The advantage is that the cleaning speed is fast and easy. The disadvantage is: the cost is relatively high, there is certain corrosion to the equipment, and the cleaning is not very thorough.
Manual cleaning is adopted, that is, when the production is stopped for maintenance, the tank is disassembled and cleaned manually. Although the cleaning is thorough, it is labor-intensive and time-consuming, and it is also accompanied by the cost of downtime and maintenance. (tips: Before manual cleaning, be sure to purge! To prevent poisoning.)
Manual cleaning of tank interiors is an inefficient, low-quality and unsafe operation, so there is an increasing need for automated tank cleaning today. Automated tank cleaning not only reduces downtime and maintenance costs, but also reduces process flow time, thereby increasing productivity.
The cleanliness of the supplied product is guaranteed by the automated cleaning of the tanks. The automatic tank cleaning can strictly control the cleaning process and ensure the integrity of the process. Cleaning the nozzle during the entire cleaning process is a key component to ensure the final cleaning effect. Considerations for tank cleaning operations are also very important in order to comply with regulations and ensure operator safety.
CYCO automatic tank cleaning technology
Six storage tanks at a large chemical plant needed to be thoroughly cleaned during a shutdown. The original tank cleaning process included watering/draining operations, supplemented by heavy manual labor. This cleaning method was also very wasteful of water and did not ensure the cleanliness of the tank after cleaning.
The customer needs a set of automated tank cleaning equipment that can provide effective and stable cleaning results, eliminate safety hazards associated with personnel operations, reduce downtime and reduce water consumption.
CYCO Tank Cleaning Nozzle 360° cleaning work inside tanks. The stainless steel components of the device can be easily mounted to the top of the jar.
When the cleaning fluid enters the cavity at high pressure from the connecting rod port, and passes through the fixed impeller, a huge impact force is formed, which drives the rotating impeller to rotate at a high speed. The main body realizes 360° rotation along the Y axis, and the X main body realizes 360° revolution around the Y axis while rotating 360° around the X axis through meshing with the bevel gear of the Y main body. Therefore, the spraying direction of the nozzle can be directed to all directions of the inner wall of the container, so as to realize all-round cleaning without dead angle.
CYCO automatic tank cleaning effect
CYCO Tank Cleaning Nozzle 360° reduces the cleaning cycle of customers by half, reduces the labor intensity of workers, reduces downtime, and provides a stable cleaning effect guarantee.
In addition, the chemical plant saved 1,000 gallons of water by switching to the CYCO Tank Cleaning Nozzle 360°, reducing the risk of injury to cleaning operations workers. These devices have saved the user approximately $36,000 per year, which equates to a return on investment in less than seven months.
