[0002] The sintering machine in the sintering plant is used to sinter the ore into blocks and remove impurities in the ore during sintering. During the operation of the sintering machine, a large amount of smoke and dust will inevitably be generated. In order to avoid the smoke and dust discharged by the sintering machine from polluting the environment and damaging the health of the workers, an electrostatic precipitator is installed at the head of the sintering machine where the smoke and dust are discharged to reduce the dust content in the discharged smoke and dust, thereby reducing the pollution to the environment and the damage to the health of the workers.

[0003] At present, flue gas is ionized multiple times before dust removal treatment to minimize the dust content in the flue gas. However, after multiple ionizations, the dust in the flue gas is smaller and lighter, and will float up to form snowflakes, which are difficult to be completely absorbed by the electrostatic precipitator, making it difficult to minimize the impact on the environment and the health of workers, which is not conducive to the protection of the environment and the health of workers.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0027] In order to describe the present invention in detail, a sintering machine head bell mouth electrostatic precipitator pre-charge device of the present invention is specifically described below:

[0028] Please combine Figures 1 to 4 As shown, the present invention provides a bell-mouth electrostatic precipitator pre-charge device for a sintering machine head, comprising a bell-mouth body 4, a dust collecting member 6 and an ionizing member 5, the bell-mouth body 4 having a cavity and an inlet for flue gas to flow in and an outlet for flue gas to flow out, the inlet and the outlet being connected through the cavity, and the direction from the inlet to the outlet being a first direction; the dust collecting member 6 is arranged in the cavity of the bell-mouth body 4; the ionizing member 5 is arranged in the cavity of the bell-mouth body 4; wherein, along the first direction, the dust collecting member 6 and the ionizing member 5 are arranged in sequence with a spacing.

[0029] In this embodiment, the ionization element 5 ionizes the smoke in the flue gas into positive and negative ions, and collects the dust through the dust collecting element 6 with different polarities. The smoke with positive ions is adsorbed on the dust collecting plate with negative polarity, and the smoke with negative ions is adsorbed on the dust collecting plate with positive polarity. The above principle can absorb the smoke in the flue gas, reduce the pollution of the flue gas to the environment, and avoid affecting human health.

[0030] The dust collecting member 6 and the ionizing member 5 are both plate-shaped, which can increase the contact area with the flue gas and enhance the ionization effect.

[0031] Specifically, the planes of the dust collecting member 6 and the ionizing member 5 are perpendicular to the first direction. The dust collecting member 6 and the ionizing member 5 arranged perpendicular to the first direction can increase the ionization and dust collection area of ​​the sintering machine head bell mouth electrostatic precipitator pre-charge device and improve the ionization and dust collection effect.

[0032] Among them, the sintering machine head bell mouth electrostatic precipitator pre-charge device includes a rapper 1, and a mounting frame is also arranged on the bell mouth body 4. The dust collecting part 6 and the ionizing part 5 are both arranged on the mounting frame. The rapper 1 is arranged corresponding to the mounting frame. When the dust collecting part 6 is not charged, the rapper 1 raps the mounting frame to make the dust on the dust collecting part 6 fall into the inner cavity of the bell mouth body 4. By setting the rapper 1, the dust on the dust collecting part 6 can fall into the bell mouth of the sintering machine head in time, ensuring the dust collecting effect of the dust collecting part 6. By setting both the dust collecting part 6 and the ionizing part 5 on the mounting frame, the rapper 1 can be easily arranged. The rapper 1 can vibrate the mounting frame to achieve the rapping of the ionizing part 5, which increases the convenience during assembly.

[0033] Specifically, the mounting frame has a crossbeam corresponding to the rapper 1, the extension direction of the crossbeam is perpendicular to the first direction, and the rapping direction of the rapper 1 is perpendicular to both the extension direction of the crossbeam and the first direction. Since the space at the bell mouth is limited, space can be saved by being perpendicular to the extension direction of the crossbeam.

[0034] In detail, the ionizer 5 is provided with a suspension assembly 3, and the suspension assembly 3 is used to suspend the ionizer 5 in the inner cavity of the bell mouth body 4. In this embodiment, a working platform is also provided at the bell mouth. Since the ionizer 5 is heavy, when it is directly welded to the bell mouth, in order to avoid the poor stability of the ionizer 5 when it is suspended, the suspension assembly 3 is provided between the working platform and the bell mouth, and the ionizer 5 is suspended in the inner cavity of the bell mouth body 4. In this embodiment, the dust collecting member 6 is light and can be directly welded to the bell mouth body 4. The installation method of the dust collecting member 6 can be adjusted according to actual production needs.

[0035] The dust collecting member 6 is an anode plate. Since the cathode is generally arranged in a linear shape, the contact area between the cathode line and the flue gas is small, and the anode is plate-shaped, which can increase the contact area with the flue gas, increase the dust collection amount, and improve the dust collection effect.

[0036] Specifically, each ionization element 5 includes two ionization plates, which are arranged in parallel and opposite to each other. Through the above arrangement, the contact area between the ionization element 5 and the flue gas is increased, and the ionization effect of the sintered joint bell mouth ionization dust removal pre-charge device is enhanced, so as to prepare for the later ionization dust collection. In addition, the two ionization elements 5 are arranged to slow down the flow rate of the flue gas, which can further enhance the ionization effect. In this embodiment, when the sintering machine head flue gas is subjected to dust removal treatment, it needs to pass through the first power plant, the second power plant, the third power plant and the fourth power plant. A sintering machine head bell mouth electrostatic precipitator pre-charge device is arranged at the bell mouth of the flue gas inlet to ionize the smoke in the flue gas in advance. When the charged smoke travels to the first power plant for ionization, since the smoke has been pre-ionized at the bell mouth, after ionization at the first power plant, most of the smoke can be ensured to be adsorbed on the anode plate and the cathode line, so that the amount of smoke in the smoke flowing into the second power plant, the third power plant and the fourth power plant is reduced, thereby ensuring the treatment effect of the smoke in the sintering smoke and reducing pollution to the environment.

[0037] In detail, the sintering machine head bell mouth electrostatic precipitator pre-charge device also includes a high-frequency boost power supply device, which is used to power the ionization element 5. The secondary boost voltage of the high-frequency boost power supply device is used to power the electric field through the through-wall porcelain bottle conductive device, and the through-wall porcelain bottle conductive device is arranged in a closed insulation box 2. In order to prevent the high-frequency boost power supply device from getting damp, the through-wall porcelain bottle conductive device is placed in the insulation box 2, which can prevent the power supply circuit from getting damp and short-circuiting, and increase the stability of the high-frequency boost power supply device when in use.

[0038] In summary, by setting the ionization element 5 at the bell mouth body, the smoke can be pre-ionized to enhance the ionization effect of the later ionization, increase the dust collection rate after the later ionization, improve the dust collection effect of the sintering machine, and reduce the impact of the sintering flue gas on the environment and the health of the workers. By setting the dust collecting element 6, a proper amount of smoke can be collected at the bell mouth to improve the dust collection effect.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
