Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a wind energy efficient self-dusting, dehydration and demisting device. Background Technique

[0002] Air pollution is mainly caused by human activities. With the rapid development of industry in China, the air environmental pollution is becoming increasingly serious. The particulate pollutants in industrial waste gas have a long residence time in the atmosphere and a long transmission distance, seriously affecting people's health and travel safety. In order to strengthen environmental protection, at present, it mainly starts from the root cause of polluted gas emissions and reduces the emissions of particulate pollutants in polluted gas.

[0003] At present, the cyclone dust removal method is usually adopted. By using the centrifugal force generated by the rotating dust-containing gas flow, the particulate pollutants are separated from the gas. That is, the cyclone dust removal device is installed at the emission source of the polluted gas. The polluted gas enters the cyclone dust removal device and blows the fan blades arranged in the cyclone dust removal device, so that the rotating shaft and the fan blades are in a rotating state. The rotating fan blades form a centrifugal wind tunnel area, generating a centrifugal force on the polluted gas entering the centrifugal wind tunnel area. Since the masses of the gas-liquid two phases in the polluted gas are different, the gas and particulate pollutants in the polluted gas are separated.

[0004] In order to increase the dust removal effect, multiple groups of fan blades are usually arranged in the existing cyclone dust removal device. The multiple groups of fan blades are arranged at intervals on the shaft body of the rotating shaft so that the polluted gas can fully contact the fan blades. However, there is a phenomenon that the rotation speed of the fan blades is low and the fan blades cannot break up the flue gas. In view of the above phenomenon, the inventor invented a wind energy efficient self-dusting, dehydration and demisting device with a novel structure. Content of the Utility Model

[0028] The following is a further detailed description of the present utility model with reference to the attached Figures 1-3 drawings.

[0029] The present utility model provides a high-efficiency self-dust-removing, dehydration and demisting device for wind energy. Refer to Figure 1 and Figure 2, including a vertical cylinder body 1, a filter screen cylinder 2, a rotating shaft 3, a fan blade assembly 4 and a paddle blade assembly 5. A through cylinder cavity 11 is opened in the cylinder body 1 along its own axis direction, and brackets 12 are respectively installed at both ends of the cylinder body 1; the rotating shaft 3 is coaxially installed in the cylinder cavity 11 of the cylinder body 1 and is rotatably connected to the bracket 12; the fan blade assembly 4 is installed at the bottom end of the rotating shaft 3, and multiple groups of paddle blade assemblies 5 are provided. The multiple groups of paddle blade assemblies 5 are installed at intervals along the length direction of the rotating shaft 3 on the shaft body of the rotating shaft 3, and the multiple groups of paddle blade assemblies 5 are all located above the fan blade assembly 4; the filter screen cylinder 2 is coaxially installed in the cylinder cavity 11 of the cylinder body 1, and the filter screen cylinder 2 is sleeved on the circumferences of the rotating shaft 3, the fan blade assembly 4 and the paddle blade assembly 5, and a chamber 13 is formed between the filter screen cylinder 2 and the inner wall of the cylinder body 1.

[0030] Referring to Figure 2 and Figure 3 , the fan blade assembly 4 includes unit fan blades 41 and a first collar 42. The unit fan blades 41 are plate-shaped bodies.

[0032] In this embodiment, the dusty and humid polluted gas enters the cylinder cavity 11 from the bottom end of the cylinder body 1 at a speed of 5.5 - 18 m / s. The fan blade assembly 4 starts to rotate under the blowing of the polluted gas. At this time, the rotating shaft 3 and the paddle blade assembly 5 rotate simultaneously. Under the action of the polluted gas flow, a turbulent flow field and a directional centrifugal force are formed in the cylinder cavity 11. At the same time, the paddle blade assembly 5 fully cuts the polluted gas, so that the gas phase, liquid phase and solid phase in the polluted gas are forced to separate. The liquid phase and the solid phase are thrown to the cylinder wall of the filter screen cylinder 2 or into the chamber 13 due to the greater centrifugal force, and the gas continues to rise upward.

[0033] Referring to Figure 1 and Figure 2 , the circumferential side wall at the bottom end of the filter screen cylinder 2 is in a closed state, and a ring plate 21 is provided at the bottom end of the filter screen cylinder 2. The inner ring part of the ring plate 21 is fixedly connected to the bottom end of the filter screen cylinder 2, and the outer ring part of the ring plate 21 is fixedly connected to the circumferential inner wall of the cylinder body 1.

[0034] Referring to Figure 1, the support 12 includes a fixed plate 121 and a connecting rod 122. The central axis of the fixed plate 121 is aligned with the central axis of the rotating shaft 3, and both ends of the rotating shaft 3 are rotatably connected to the wall of the fixed plate 121; multiple groups of connecting rods 122 are provided, and the multiple groups of connecting rods 122 are annularly arranged on the circumferential side wall of the fixed plate 121.

[0037] The implementation principle of a wind energy efficient self-dust-removing, dehydration and fog-eliminating device of the present utility model is as follows:

[0038] The dusty and humid polluted gas enters the cylinder cavity 11 from the bottom end of the cylinder body 1. The unit fan blades 41 start to rotate under the blowing of the flowing polluted gas. At this time, the rotating shaft 3 and the blade assembly 5 rotate simultaneously. Under the action of the polluted gas flow, a turbulent flow field and a directional centrifugal force are formed in the cylinder cavity 11. The rotating unit blades 51 fully cut the polluted gas, so that the gas phase, liquid phase and solid phase in the polluted gas are forced to separate. The liquid phase and solid phase are thrown to the wall of the filter screen cylinder 2 or into the chamber 13 due to the greater centrifugal force. The filter screen cylinder 2 blocks large-size particulate pollutants. The water entering the chamber 13 converges into the confluence groove 211 under the action of its own gravity and flows out from the drainage hole 212. The treated gas then continues to rise until it flows from the top end of the cylinder body 1 to the external environment.

[0039] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model should be covered within the protection scope of the present utility model.
