Description

Technical Field

[0001] The utility model relates to a dust collector structure, in particular to a front electric field flow-blocking structure for a dust collector. Background Art

[0002] Bag dust collectors, cyclone dust collectors, electrostatic precipitators, wet dust collectors and composite dust collectors are the main dust removal equipment on the market. Electrostatic precipitators are essential supporting equipment for thermal power plants. Electrostatic precipitators ionize gases through discharge at the discharge electrode, and particulate pollutants acquire electron charge. The charged particulate pollutants then move to the collecting electrode and deposit on the collecting electrode plate. Finally, the particulate pollutants on the collecting electrode are removed into the ash hopper to achieve the purpose of removing particulate pollutants in the flue gas. Electrostatic precipitators have the advantages of high dust removal efficiency, small pressure loss, low energy consumption and good applicability. Their function is to remove particulate smoke in the flue gas emitted by stoves or oil-fired boilers, thereby greatly reducing the amount of smoke discharged into the atmosphere.

[0003] Generally, the front-stage electric field is used to remove large particles of smoke, while the final electric field is used to remove small, sticky smoke. If the front-stage electric field does not completely retain large particles, some large particles of dust will easily flow to the final electric field, occupying the space of the final electric field plates that are supposed to process small particles of smoke, causing the plates of the final electric field to work overloaded and need to be cleaned or replaced in a time far less than the service life, which greatly affects the overall dust removal efficiency.

[0004] Therefore, this case aims to provide a front electric field flow-blocking structure for a dust collector, which can control the intake speed of the flue gas before the smoke enters the front electric field, so that the front electric field can process the smoke as comprehensively as possible under the premise of its own processing load, thereby reducing the pressure of the final electric field and improving the dust removal efficiency. Utility Model Content

[0006] The utility model is achieved in this way:

[0007] A front electric field flow-blocking structure for a dust collector, arranged between the air inlet end of the dust collector and the front electric field, comprises:

[0008] A front-stage smoke blocking structure, the front-stage smoke blocking structure includes several groups of blocking members corresponding to the air inlet position of the front-stage electric field, the blocking members include an air duct connected to the air inlet end of the dust collector and the air inlet end of the front-stage electric field, and several movable guide frames arranged in the air duct, the movable guide frames are alternately arranged, the gaps between adjacent movable guide frames are used to allow smoke to flow, and the angles of the movable guide frames are adjusted to adjust the gaps between adjacent movable guide frames.

[0009] As a further improvement, the movable guide frame includes a yaw motor hingedly installed in the air guide duct, and a swing plate connected to the rotating shaft of the yaw motor through a sleeve, and a movable plate locked on the swing plate by rivets. When the yaw motor drives the movable plate to swing, a channel for smoke and dust to pass through is formed between two adjacent movable plates.

[0010] As a further improvement, the movable sheet is a solid alloy plate.

[0011] As a further improvement, the movable sheet is a spoiler structure, which includes a hollow installation frame, a central axis inserted in the installation frame, a flip plate whose center line is penetrated by the central axis, and a plurality of mesh holes are opened on the flip plate.

[0012] As a further improvement, a plurality of pole plates are arranged in the front-stage electric field, an induction structure is connected to the pole plate, and the induction structure is electrically connected to the yaw motor.

[0013] As a further improvement, the sensing structure is a light sensor, and the light sensor is facing the electrode plate, or the sensing structure is a weight sensor.

[0014] The beneficial effects of the utility model are:

[0015] The front-stage electric field is suitable for processing coarse dust particles in the smoke and reducing the pressure of the final electric field. If the front-stage electric field cannot absorb most of the coarse dust, it will directly affect the cleanliness of the output dust collector gas. In this regard, the utility model sets a front-stage smoke blocking structure at the front end of the front-stage electric field, guides the travel route of the smoke through the air guide duct in the front-stage smoke blocking structure, and controls the travel amount of the smoke through a number of movable guide frames. When a large amount of smoke is attached after the front-stage electric field has worked for a long time, the gap between the movable guide frames is made smaller to allow The space for smoke and dust to circulate becomes smaller, and the air intake of smoke and dust decreases, so that the front-stage electric field can have a certain amount of time to clean the accumulated dust or process it step by step. After the front-stage electric field has cleaned the accumulated dust, due to the improved cleaning capacity at this time, a larger circulation channel can be opened, that is, the gap between the movable guide frames is enlarged, so that the amount of smoke and dust flowing through the front-stage electric field becomes larger, and the front-stage smoke blocking structure can automatically control the air intake according to the processing capacity of the front-stage electric field, so that all the smoke and dust flowing through the front-stage electric field can be better processed, and the pressure of the final electric field is reduced.

[0021] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0022] Reference Figure 1 to Figure 3As shown, a front electric field flow blocking structure for a dust collector is arranged between the air inlet end 10 of the dust collector and the front electric field 20, including: a front flue gas blocking structure, the front flue gas blocking structure includes a plurality of groups of blocking members 31 corresponding to the air inlet position of the front electric field 20, the blocking member 31 includes an air guide 311 connected to the air inlet end 10 of the dust collector and the air inlet end of the front electric field 20, and a plurality of movable guide frames 312 arranged in the air guide 311, the movable guide frames 312 are alternately arranged at intervals, and the gaps between adjacent movable guide frames 312 are used to allow the flue gas to flow, and the angles of the movable guide frames 312 are adjusted to adjust the gaps between adjacent movable guide frames 312.

[0023] During the dust removal process, the smoke source enters from the position of the dust collector air inlet end 10, and then enters a plurality of front-stage electric fields 20 after being blocked by the front-stage smoke blocking structure.

[0024] The front-stage electric field 20 is suitable for processing coarse dust particles in the smoke and reducing the pressure of the final electric field 30. If the front-stage electric field 20 cannot absorb most of the coarse dust, it will directly affect the cleanliness of the output dust collector gas. In this regard, the present invention sets a front-stage smoke blocking structure at the front end of the front-stage electric field 20, guides the travel route of the smoke through the air guide duct 311 in the front-stage smoke blocking structure, and controls the travel amount of the smoke through a plurality of movable guide frames 312. When a large amount of smoke is attached to the front-stage electric field 20 after working for a long time, the gap between the movable guide frames 312 and the movable guide frames 312 is made smaller. The space through which smoke can circulate is made smaller, and the air intake of smoke is reduced, so that the front-stage electric field 20 can have a certain amount of time to clean the accumulated dust or process it step by step. After the front-stage electric field 20 cleans the accumulated dust, since the cleaning capacity is improved at this time, a larger circulation channel can be opened, that is, the gap between the movable guide frame 312 and the movable guide frame 312 is enlarged, so that the amount of smoke flowing to the front-stage electric field 20 is increased, and the front-stage smoke blocking structure can automatically control the air intake according to the processing capacity of the front-stage electric field 20, so that all the smoke flowing through the front-stage electric field 20 can be better processed, and the pressure of the final electric field 30 is reduced.

[0025] Each set of transverse plates 21 in the front-stage electric field 20 forms a row, and the gap between each row forms a channel for gas to flow in, and the air guide duct 311 is arranged corresponding to the channel.

[0026] In this embodiment, the electrode plate 21 used in the front-stage electric field 20 is a 480-shaped plate.

[0027] The specific setting of the movable guide frame 312 is as follows: the movable guide frame 312 includes a yaw motor 3121 hingedly installed in the air guide duct 311, and a swing plate 3122 sleeved on the rotating shaft of the yaw motor 3121 through a sleeve, and a movable sheet 3123 locked on the swing plate 3122 by rivets. When the yaw motor 3121 drives the movable sheet 3123 to swing, a channel for smoke and dust to pass through is formed between two adjacent movable sheets 3123. During actual use, the yaw angle of the yaw motor 3121 is generally in the swing range of 30° to 120°, and can also be in a horizontal state. When the yaw motor 3121 swings, it can drive the swing plate 3122 to swing and then drive the movable sheet 3123 to swing, so that there is a certain gap between the movable sheets 3123 and the movable sheets 3123 to allow smoke and dust to pass through.

[0028] The above-mentioned yaw motor 3121 is adjusted according to the actual situation of the front-stage electric field 20. Specifically, a plurality of pole plates 21 are arranged in the front-stage electric field 20. An induction structure is connected to the pole plate 21. The induction structure is electrically connected to the yaw motor 3121. The weight of the particles on the pole plate 21 is sensed by the induction structure, and the yaw angle is changed according to the information of the induction structure. The induction structure mentioned in this embodiment can be a weight sensor or a light sensor. If it is a weight sensor, the pole plate 21 of the front-stage electric field 20 needs to be set in a suspended manner. If a light sensor is used, the light sensor is opposite to the pole plate 21. Since it is a prior art, it will not be described in detail here.

[0029] In this embodiment, in order to facilitate guiding, the movable sheet 3123 is a solid alloy plate. At this time, the movable sheet 3123 plays the role of shielding and guiding, allowing the smoke to flow along the inclined direction of the movable sheet 3123.

[0030] In the setting process of other embodiments, the movable sheet 3123 is a spoiler structure, which includes a hollow installation frame 231, a central axis 232 inserted in the installation frame 231, and a flip plate 233 whose center line is penetrated by the central axis 232. A plurality of mesh holes are provided on the flip plate 233. At this time, the movable sheet 3123 has a spoiler effect, which can spoil the smoke passing through here, allowing the smoke to pass through the mesh holes on the flip plate 233 in a disorderly manner, and the blocking effect is related to the rotation speed of the output structure of the central axis 232. The output structure of the central axis 232 can be a miniature rotating motor.

[0031] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
