TECHNICAL FIELD

[0001] The present application relates to the field of dust removal device, more particularly, to a water vortex fan adsorption type dust removal device. BACKGROUND

[0002] Dust removal is to separate dust from flue gas, and the equipment used is called dust remover or dust removal device. The performance of the dust remover is expressed by the amount of gas that can be handled, the resistance loss of the gas passing through the dust remover and the dust removal efficiency. At the same time, the price, operation and maintenance cost, service life and operation management difficulty of the dust remover are also important factors to consider its performance. In the existing dust removal equipment, most of them are transported by the fan, and the resistance of the dust remover leads to very high energy consumption, and at the same time, the efficiency is low, and in some working conditions, the impeller of the fan will be worn by the dust, and in some working conditions, the dust will adhere to the impeller and destroy the dynamic balance of the impeller. The above reasons all lead to high operation and maintenance cost of the dust removal system. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present application is to provide a water vortex fan adsorption type dust removal device with low energy consumption, high efficiency and low operating cost. The conveying fan of the dust removal device is combined with the dust removal device.

[0004] In order to achieve this purpose, the technical scheme adopted by the present application is as follows:

[0005] The present application provides a water vortex fan adsorption type dust removal device, which comprises a water vortex generator, a water inlet and a plurality of water outlets are arranged on the water vortex generator, the water inlet is located at the bottom of the water vortex generator, the water outlets are located on the side wall of the water vortex generator shaft body and are distributed in a central symmetric manner around the axis of the water vortex generator shaft body, the inside of the water vortex generator is a hollow spiral channel, and the spiral channel communicates the water outlets with the water inlet; a hollow shaft, which is a hollow pipe structure, is arranged on the water vortex generator through a sealing bearing, the top of the hollow shaft is inserted into the water outlet of the water vortex generator and communicates with the water outlet of the water vortex generator; water flows into the spiral channel through the hollow shaft and is discharged from the water outlet to form a water curtain rotor, and when the high-speed water flow passes through the spiral channel, it will drive the water vortex generator to rotate, so that the water curtain rotor rotates to generate a negative pressure suction force to suck in the dust smoke.

[0006] In the preferred technical scheme of the present application, a vertical upward pipe is sleeved on the water vortex generator, the hollow shaft on the water vortex generator is fixed in the pipe through a support, one side of the pipe is provided with a dust pipe, and the height of the dust pipe is lower than the horizontal height of the water vortex generator.

[0007] Further, the bottom of the pipeline is provided with a water storage pool, and a high-pressure water pump is arranged in the water storage pool.

[0008] Further, the top of the pipeline is provided with a demister for removing water mist.

[0009] Further, the water storage pool is further provided with a filter screen for water flow.

[0010] The present application has the following advantages:

[0011] (1) In the present application, the high-pressure water pump in the water storage pool directs the water in the water storage pool to the water inlet of the water vortex fan generator. The high-pressure water enters the water inlet at the lower end of the water vortex fan generator through the hollow shaft. The water flow passes through the special flow channel in the water vortex fan generator and is discharged from the water discharge port, forming a plurality of fan-shaped water knife-shaped water flows like a fan-shaped fan. The water vortex fan generator rotates at high speed under the reaction force of the fan-shaped water flow. The water flow discharged from the plurality of water discharge ports of the water vortex fan generator forms a forward pushing rotary water curtain, which pushes the flue gas to flow, and negative pressure is generated behind the rotary water curtain.

[0012] (2) In the present application, the dust smoke in the smoke pipe is sucked into the pipeline. When the dust smoke passes through the water curtain rotary vane, it is scattered by the water curtain rotary vane. The particulate impurities in the dust smoke are adsorbed by the water in the water curtain rotary vane and are scattered to the inner wall of the pipeline. Under the influence of gravity, the water flows into the water storage pool. The filter screen in the water storage pool can filter the water flow with particulate impurities, so that the water can be reused.

[0013] (3) In the present application, the gas in the dust smoke continues to float upward after passing through the water curtain rotary vane, so as to enter the demister. After the demister removes the water in the gas, it is discharged from the pipeline. The dust removal device also has the advantages of convenient operation and easy implementation.

The hollow, pipe-like structure has a hollow shaft 12 mounted on the water vortex generator 1 via a sealed bearing 14. The top of the hollow shaft 12 is inserted into the water jet 2 of the water vortex generator 1 and is connected to the water jet 2. Water flows through the hollow shaft 12 into the spiral channel 4 and is discharged from the water jet 2, forming a water curtain vortex blade 5. When the high-speed water flows through the spiral channel 4, it will drive the water vortex generator 1 to rotate, causing the water curtain vortex blade 5 to rotate as well, thereby generating negative pressure suction to draw in dust and smoke.

[0025] The working process and principle of the present application are as follows: when in use, the high-pressure water pump 8 in the water storage pool 7 sprays the water in the water storage pool 7 into the hollow shaft 12, the high-pressure water enters the water inlet 2 at the lower end of the water vortex fan generator 1 through the hollow shaft 12, the water flow passes through the special flow channel in the water vortex fan generator 1, and is sprayed from the water spraying port 3 to form a plurality of fan-shaped water knife-shaped water flows like fan page fans, the water vortex fan generator 1 generates a rotating torque to rotate at high speed under the reaction force of the fan-shaped water flows, the water flows sprayed from the plurality of water spraying ports 2 of the water vortex fan generator 1 form a forward pushing rotating water curtain, push the flue gas to flow, and a negative pressure is generated at the rear of the rotating water curtain to suck the dust and smoke in the smoke pipe 9 into the pipeline 6;

[0026] Then the dust and smoke is scattered by the water curtain rotating vane 5 when passing through the water curtain rotating vane 5, the particulate impurities of the dust and smoke are adsorbed by the water in the water curtain rotating vane 5, and are scattered to the inner wall of the pipeline 6, and are affected by gravity to flow into the water storage pool 7, the filter screen 11 in the water storage pool 7 can filter the water flow with particulate impurities, so that the water can be repeatedly used;

[0027] Finally, the gas in the dust and smoke continues to float upward after passing through the water curtain rotating vane 5, so as to enter the demister 10, and the demister 10 discharges the gas after removing the water content in the gas from the pipeline 6.
