Cyclone dirt remover

The following is what I found on Baidu; it is for reference only. A cyclone dirt remover uses the principle of centrifugal separation to remove contaminants. Since the water inlet pipe is installed at an eccentric position on the cylinder, when water passes through this inlet pipe, it first forms a downward-sloping circular flow along the tangent direction of the cylinder’s circumference. As the water flows, it moves downward in a rotational motion; when it reaches a certain point in the cone-shaped structure, it starts rotating upward along the axis of the cylinder, and finally exits through the outlet pipe. Under the effect of inertial centrifugal force and gravity, the contaminants fall along the walls of the cone into the conical sediment chamber at the bottom of the device. There are no components at the bottom of the cone to prevent contaminants from rising back up. When the amount of contaminants accumulated in the sediment chamber reaches a certain level, simply opening the manual butterfly valve allows them to flow out of the cyclone dirt remover under the force of the water flow. Therefore, this type of dirt remover does not require the installation of front/back valves, bypass pipes, or bypass valves, which makes it more space-efficient and less costly to install. The cyclone dirt remover is a dirt removal device with high efficiency, as well as being extremely convenient and reliable for cleaning. It is capable of handling impurities such as rust and sediment with an average density of 1.8 g/cm3, and its separation threshold is 0.07 mm. When the particle size is 0.3 mm, its dirt removal efficiency can reach 97%; there is absolutely no risk of clogging, and no special exhaust system is required. It is the only dirt remover that does not suffer from clogging, and it offers advantages unmatched by conventional filter-based dirt removers in terms of ensuring the safe operation of water systems. The cyclone dirt remover can clean itself while in operation, without the need to shut down the water pump. During cleaning, the butterfly valve is opened slowly; first, wastewater flows out, followed by turbid water, and finally clean water. As the clean water flows out, it cleans the rubber lining of the butterfly valve body, which means that no leaks occur once the valve is closed. This has been proven in practice. During installation, it is necessary to direct the wastewater to a drainage ditch. The local resistance system coefficient of the swirl dirt remover is low (only 3.0). Since there is no filter mesh inside the swirl dirt remover, there is no risk of the filter mesh getting clogged by dirt, which could otherwise lead to increased system resistance, insufficient flow rate, and uneven head losses in the system.

The swirl dirt remover utilizes the principle of centrifugation, completely breaking away from the traditional approach of using filters for dirt removal; this ensures low and consistent resistance in the pipeline system, allowing for dirt removal without shutting down the system. It is most suitable for removing solid impurities such as sediment, stones, and pipe wall debris from the pipelines, ensuring the proper operation of the system.

The last edit to this post was made by AOJIE on 2014-6-1 at 19:05. To achieve good performance when using a cyclone dirt remover, it must operate at an appropriate flow rate; if the flow rate is too high, the liquid stays in the remover for a short time, which hinders separation； When the flow rate is too low, the centrifugal force inside the dirt remover is insufficient, preventing the separation of solids from liquids. Therefore, the flow rate must be selected appropriately; the actual conditions of customers vary, and it is not possible to rely solely on the diameter of the circulation pipe for making decisions. A more effective expansion-type dirt remover should be used in the circulating water system; by reducing the flow rate of the circulating water, all debris in the system settles due to gravity, thereby removing the contaminants.

Is there a ratio between the import and the diameter?

Does it fall under the category of pressure vessels? The design pressure is 1.6 MPa, but it seems that the wall thickness wasn’t determined based on SW6 standards. What’s the deal with water treatment systems?
