[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] A polymer dust collector used in a dust removal tower is installed on the top of the tower body, and the shell is a carbon steel structure; the core component cyclone is made of polymer modified PP material, which has a low relative density, very good mechanical properties, and stronger impact resistance, especially for scenes with high water flow scouring with a certain pressure, and is suitable for high flow rate occasions of centrifugal cyclone; combined with Figure 1 As shown, it includes a water collecting tank 1, a flow guide accelerator 2, a centrifugal impeller 3, a flushing pipe 4, a flow guide pipe 5, a mounting rod 6, a reinforcing rod 7, a rotating shaft 8, an adjusting rod 9, and a load adjusting plate 10.

[0017] The water collecting tank 1 is cylindrical and vertically arranged to contain liquid thrown onto the inner wall of the water collecting tank 1. The liquid droplets are collected in the water collecting tank 1 under the action of gravity.

[0018] A vertically arranged rotating shaft 8 is provided on the top of the water collecting tank 1, the upper part of the rotating shaft 8 is connected to the power mechanism, and the lower part of the rotating shaft 8 is connected to the centrifugal impeller 3, which is located in the middle of the water collecting tank 1. A plurality of blades with a certain angle are arranged in the centrifugal impeller 3, which can prolong the gas-liquid mass transfer time of the flue gas and separate and remove the fine dust droplets in the flue gas by changing the running path of the flue gas in the blades.

[0019] The centrifugal impeller 3 is provided with two vertically arranged mounting rods 6, and there is a distance between the mounting rods 6 and the water collecting tank 1. The mounting rods 6 pass through the lower end surface of the water collecting tank 1, and the top of the mounting rods 6 is higher than the height of the centrifugal impeller 3.

[0020] The middle part of the mounting rod 6 is provided with a flow guide accelerator 2 coaxially arranged with the water collecting tank 1, and the flow guide accelerator 2 is located at the lower end surface of the water collecting tank 1. The flow guide accelerator 2 is in a truncated cone shape, and the lower diameter of the flow guide accelerator 2 is larger than the upper diameter; by reducing the cross section of the flue gas flow, the flow velocity of the flue gas is quickly increased, and a certain kinetic energy is provided for the centrifugal separation and dehydration of the downstream impeller.

[0021] The bottom end of the mounting rod 6 is provided with an adjusting rod 9, on which a load adjusting plate 10 is provided, and the load adjusting plate 10 is connected to an online adjusting mechanism provided outside the tower. The online adjusting mechanism automatically adjusts part of the load adjusting plate 10 to rotate to a closed state according to the differential pressure value before and after the online monitoring device, thereby ensuring the flue gas flow rate in other purification devices. Because the dehydration of the centrifugal impeller 3 is greatly related to the flow rate, a certain flow rate must be met to achieve the best centrifugal dehydration effect.

[0022] The edge of the bottom of the water collecting tank 1 is connected with a plurality of vertically arranged guide pipes 5. One end of the guide pipe 5 is connected to the bottom of the water collecting tank 1, and the other end is directly discharged below the regulating rod 9, out of contact with the upward flue gas, avoiding secondary entrainment of gas and liquid.

[0023] A flushing pipe 4 is provided in the middle of the centrifugal impeller 3 for cleaning the centrifugal impeller 3. The flushing pipe 4 is connected to a flushing main pipe providing a water source to ensure that the blades on the centrifugal impeller 3 are clean.

[0024] A reinforcing rod 7 is provided in the middle of the mounting rod 6, and the reinforcing rod 7 is connected to the flow guide accelerator 2 to ensure the stability of the connection.

[0025] In actual use, when the purified flue gas containing water is accelerated by the guide accelerator 2, the centrifugal impeller 3 guides the dehydration impeller to accelerate the rotation speed of the flue gas, generating a stronger centrifugal force. After the water in the flue gas is forced to be thrown to the water collection tank 1, the fine droplets, fine dust particles, aerosols and other tiny particles in the flue gas collide with each other and agglomerate into large droplets and flow down along the wall. The purified flue gas continues to move upward, realizing effective separation of gas and liquid to achieve the purpose of dehydration and dust removal. After the dehydration and dust removal process is completed, the flue gas after purification is discharged.

[0026] In order to ensure the cleanliness of the centrifugal impeller 3 and the water collecting tank 1 and improve the dust removal and dehydration effect, the flushing pipe 4 is set with an interlocking logic for regular flushing.
