Advantages of swirl desanders

Swirl desanding device adopts swirl separation technology to work, swirl separation is a high-efficiency and energy-saving separation technology, according to the principle of ion sedimentation and density difference, when the water flow enters the equipment tangentially from the inlet of the desanding device under a certain pressure, it swirls at high speed in the equipment to generate a centrifugal field
。 Due to the different densities of the two solid-liquid states of sand and water, under the action of centrifugal force, centripetal buoyancy, liquid drag, dense solids or impurities are thrown around, because the lower part of the equipment is a cone structure, the tangential rotation speed of solids or impurities with the continuous reduction of the radius of the cone is getting faster and faster, zui is deposited to the bottom of the equipment and discharged with the sewage discharge, and the liquid with low density rises and is discharged from the water outlet, the equipment can effectively remove gravel, scale, calcareous matter and other tiny solids, separated from the system and eliminated
。 In a certain range and under certain conditions, the greater the water inlet pressure of the desanding device, the higher the sand removal rate
.
The equipment has the advantages of convenient cleaning during operation: 1.
Since the filter pipe is blocked by suspended debris only occurs in the early stage of system operation, and the main dirt is discharged by the sewage valve, there is no need to set up a bypass pipe
when using the S-shaped swirl desanding device.
Due to the reason that the filter pipe needs to be cleaned regularly, the sewage outlet of the inlet and outlet should be set with a gate valve, and the outlet of the sewage pipe where the sewage valve is located should be located in a safe place and there is enough cleaning space 2.
When the pressure difference between the front and rear of the desander is large, the pump should be stopped to clean the filter pipe
.
If there is no suspended solids blockage after 15 days of operation of the new heat network or no suspended solids after 15 days of cleaning the filter tube, it will enter a normal working state and discharge sewage regularly
