Description

Technical Field

[0001] This utility model relates to the field of environmental protection and dust removal technology, and in particular to a feed trough device for a multi-tube dust collector. Background Technology

[0002] High-temperature flue gas is often generated in chemical, metallurgical, power and other industries, mainly using coal as an energy source. The flue gas produced by coal combustion is a source of air pollution. In recent years, environmental protection requirements have become increasingly important. In order to control the harm of flue gas to the atmosphere, various enterprises that emit flue gas are required to conserve energy and reduce emissions.

[0003] Power companies emit large amounts of flue gas during production, which contains a large amount of particulate matter and pollutes the atmosphere. To address the need for ultra-low / ultra-clean emission retrofitting and heavy pollution emission reduction, this application discloses a feed trough device for a multi-tube dust collector. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a feed trough device for a multi-tube dust collector.

[0005] This utility model is achieved through the following technical solution: a material guide trough device for a multi-tube dust collector, including a flue, a flue gas distribution plate is inclinedly arranged inside the flue, a plurality of dust collection rods are arranged vertically and at intervals above the flue gas distribution plate, the upper end of the dust collection rod is connected to a horizontal bar, the horizontal bar is connected to the inner wall of the flue, the lower end of the dust collection rod is integrally connected to a rod tip, a negative pressure hole is arranged directly below the rod tip, the negative pressure hole is arranged inside the upper wall of the upper negative pressure pipe, one end of the upper negative pressure pipe extends through to the outside of the flue and connects to the main pipe one, the lower end of the flue gas distribution plate is connected to the end of the lower negative pressure pipe, and the lower negative pressure pipe extends through the upper part of the flue and connects to the main pipe two.

[0006] As a further improvement to the above scheme, the flue gas distribution plate is configured in a W-shaped structure, and several flue gas holes are provided on the flue gas distribution plate at intervals and in a continuous manner on the valley peaks.

[0007] As the flue gas rises, it ascends through the flue gas holes in the direction of the flue gas flow. The particulate matter in the flue gas will be charged with ions, and some of the particulate matter will gather at the bottom of the flue gas distribution plate to facilitate its discharge.

[0008] As a further improvement to the above solution, the crossbar is made of insulating material, and a conductive inner core is provided inside the crossbar. The conductive inner core is connected to the upper end of the dust collection rod. One end of the crossbar passes through the side wall of the flue, and the conductive inner core extends to the outside and is sleeved on the terminal board. A terminal post is connected to the terminal board.

[0009] By connecting the power supply through the terminal block, the terminal block and the conductive core become conductive. The dust collection rod is then suspended by a horizontal bar, and the conductive core imparts an anode charge to the dust collection rod, which adsorbs and collects particulate matter in the flue gas. The rising airflow of the flue gas causes the collected particulate matter to be collected by the negative pressure of the upper negative pressure pipe.

[0010] As a further improvement to the above scheme, a second terminal is connected to one side of the flue gas distribution plate, and a cathode charge is connected through the terminal. The charge energizes the particulate matter in the flue gas, so that the particulate matter carries cathode charge ions.

[0011] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The negative pressure suction generated by the dust collector is used by the main pipe 1 and the main pipe 2 to drive the particles on the flue gas distribution plate and the particles adsorbed at the lower end of the dust collection rod into the upper negative pressure pipe and the lower negative pressure pipe, thereby achieving the purpose of guiding the displacement of the particles. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 A schematic diagram of the relevant structure for installing material guides inside the flue. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 2 As shown,

[0016] A material guide trough device for a multi-tube dust collector includes a flue 1. A flue gas distribution plate 2 is inclinedly arranged inside the flue 1. Several dust collection rods 3 are arranged vertically and at intervals above the flue gas distribution plate 2. The upper end of the dust collection rod 3 is connected to a crossbar 4. The crossbar 4 is connected to the inner wall of the flue 1. The lower end of the dust collection rod 3 is integrally connected to a rod tip 31. A negative pressure hole 81 is arranged directly below the rod tip 31. The negative pressure hole 81 is located inside the upper wall of the upper negative pressure pipe 8. One end of the upper negative pressure pipe 8 extends to the outside of the flue 1 and connects to the main pipe 9. The lower end of the flue gas distribution plate 2 is connected to the end of the lower negative pressure pipe 11. The lower negative pressure pipe 11 extends through the upper part of the flue 1 and connects to the main pipe 2 12.

[0017] As a further improvement to the above scheme, the flue gas distribution plate 2 is configured in a W-shaped structure, and a number of flue gas holes 21 are provided on the flue gas distribution plate 2 at intervals and through the peaks and valleys.

[0018] During the upward movement of the flue gas, the flue gas rises through the flue gas holes 21 in the direction of the flue gas. The particulate matter in the flue gas will be charged with ions, and some of the particulate matter will gather at the bottom of the flue gas distribution plate 2 to facilitate the accumulation and discharge.

[0019] As a further improvement to the above solution, the crossbar 4 is made of insulating material, and a conductive inner core 5 is provided inside the crossbar 4. The conductive inner core 5 is connected to the upper end of the dust collection rod 3. One end of the crossbar 4 passes through the side wall of the flue 1, and the conductive inner core 5 extends to the outside and is sleeved on the terminal plate 6. A terminal post 7 is connected on the terminal plate 6.

[0020] Connect the power supply using terminal 7 to make terminal block 6 and conductive core 5 conductive. Then, suspend dust collection rod 3 through crossbar 4 and use conductive core 5 to give dust collection rod 3 an anode charge ion to adsorb and collect particulate matter in flue gas. Use the rising airflow of flue gas to collect the accumulated particulate matter through the negative pressure of upper negative pressure pipe 8.

[0021] As a further improvement to the above scheme, the flue gas distribution plate 2 is connected to terminal 10 on one side, and cathode charge is connected through terminal 10. The charge energizes the particulate matter in the flue gas, so that the particulate matter carries cathode charge ions.

[0022] The charge on the "W"-shaped flue gas distribution plate in the direction of rising flue gas can pre-charge the dust before it enters the dust collector. Part of the charged dust is captured by the distribution plate, and the other part enters the internal space of the electric field, releasing the dust collection pressure inside the electric field and improving the dust removal efficiency. The needle tip of the device is directly opposite the trough of the "W"-shaped distribution plate, generating a circular tube discharge effect. Its discharge is uniform and the corona intensity is high. The needle tip is directly opposite the airflow to form an electric wind wall, which enhances the charging of dust.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
