There is no other good solution; one can only make an opening on the side to install a manhole.
An annular pipe is installed outside; from this annular pipe, several branch pipes extend into the cyclone separator for cleaning via water spraying
Apart from manholes or equipment flanges, try steam purging if conditions permit and it is feasible
Install an additional nozzle in areas with dead corners
All the cyclones we design come equipped with cleaning nozzles in the middle; if you use the approach you described, water will just flow past the equipment, and there will definitely be dead zones
There must also be dead corners in the middle design. Could you show the image?

Traditional cleaning of tanks and reactors is mainly carried out by manual methods or by automatically filling and draining the cleaning solution. Both approaches have significant drawbacks: they fail to clean the tank surfaces thoroughly, result in low cleaning efficiency, lead to waste of cleaning agents, and do not ensure safety for personnel. The high-pressure nozzle cleaning system can automatically carry out and monitor the entire cleaning process in real time, ensuring a thorough 360-degree cleaning of the inside of the tank. It delivers high-quality cleaning results, and it is able to adjust the intensity of the impact force based on the varying degree of adhesion of different products to the inner walls, thus providing a uniform and consistent cleaning effect ; (2) Cleaning cycle. The cleaning cycle for traditional tanks and reactors is limited by the size of the vessels and the adhesion of the product to their inner walls, resulting in long processing times. High-pressure nozzle cleaning allows for the adjustment of the appropriate impact force based on the product’s adhesion to the inner walls, thereby significantly reducing the cleaning time ; (3) Safety. The high-pressure nozzle cleaning system uses closed-loop cleaning; no workers need to enter the tank during the cleaning process, which prevents harm to the workers from the toxicity of the products and other hazards. It also enables automatic monitoring of all components. (4) Economic benefits. High-pressure nozzle cleaning enables the greatest cleaning effect with the minimum amount of cleaning fluid. The liquid used for cleaning can be reused, which not only saves on the high costs associated with manual cleaning but also reduces the use of cleaning agents, thereby lowering the costs related to the treatment of waste fluids.
