[0002] In industrial production, in order to meet environmental protection requirements, it is usually necessary to adopt relevant dust removal equipment to effectively improve environmental protection indicators. Dust collector is one of the more important dust removal equipment, especially the new high-voltage electric precipitator equipment is widely used. Although this equipment has high dust removal efficiency (dust removal efficiency of more than 99%) and a wide range of applications (including high-temperature flue gas), it requires regular maintenance in the high-voltage electric field to ensure its normal operation. During the regular maintenance process, production must be stopped for professional personnel to perform maintenance and inspection, and each maintenance and inspection time is too long, seriously affecting production efficiency.

[0003] Therefore, there is an urgent need for an electrostatic precipitator system and a nickel-iron production system, in which the production line can still operate normally and remove dust normally during the maintenance of the dust collector. Utility Model Content

[0004] The purpose of the utility model is to provide an electrostatic precipitator system and a nickel-iron production system, aiming to solve the technical problem that the traditional dust removal system needs to stop production during maintenance and overhaul, which affects the production efficiency.

[0005] To achieve the above objectives, in a first aspect, the present invention provides an electrostatic precipitator system, comprising a first dust removal production line and a second dust removal production line.

[0006] The first dust removal production line includes a first dust settling chamber, a first dust collector, and a first control valve disposed between the first dust settling chamber and the first dust collector and used to control the communication between the two;

[0007] The second dust removal production line includes a second dust settling chamber and a second dust collector, and a second control valve disposed between the second dust settling chamber and the second dust collector and used to control the communication between the two;

[0008] The first ash settling chamber and the second ash settling chamber are connected to each other through a flue gas pipeline, and a third control valve for controlling the connection between the flue gas pipeline is provided.

[0009] As a further improvement of the above solution, a fourth control valve is further provided between the first dust settling chamber and the first dust collector;

[0010] A fifth control valve is further provided between the second dust settling chamber and the second dust collector.

[0011] As a further improvement of the above solution, the first dust settling chamber is provided with a first air inlet, and the first dust collector is provided with a first air outlet;

[0012] The second dust collecting chamber is provided with a second air inlet, and the second dust collector is provided with a second air outlet. As a further improvement of the above solution, the electrostatic precipitator system further includes a controller, and the first control valve, the second control valve and the third control valve are all electrically controlled valves, which are electrically connected to the controller respectively.

[0013] As a further improvement of the above solution, the fourth control valve and the fifth control valve are both electrically controlled valves, and are electrically connected to the controller respectively.

[0014] In a second aspect, the present invention further provides a nickel-iron production system, comprising the electrostatic precipitator system provided in the first aspect, wherein a first dust removal production line is connected to a first submerged arc furnace, a first rotary kiln, and a first drying kiln, respectively, and is used to collect the flue gas and / or high-temperature flue gas generated by the first submerged arc furnace, the first rotary kiln, and the first drying kiln and enter the first ash settling chamber;

[0015] The second dust removal production line is connected to the second submerged arc furnace, the second rotary kiln and the second drying kiln respectively, and is used to collect the flue gas and / or high-temperature flue gas generated by the second submerged arc furnace, the second rotary kiln and the second drying kiln and enter the second ash setting chamber.

[0016] Since the utility model adopts the above technical solution, the beneficial effects of this application are:

With such an arrangement, when the first dust collector of the first dust removal production line is connected to the first dust collector of the first dust removal production line, a control valve is arranged between the first dust collector of the first dust removal production line and the second dust collector. When performing maintenance and overhaul, it is only necessary to cut off the first control valve between the first ash setting chamber and the first dust collector, and at the same time open the third control valve between the first ash setting chamber and the second ash setting chamber, so that the flue gas and / or high-temperature flue gas generated by the first submersible furnace, the first rotary kiln and the first drying kiln connected to the first ash setting chamber can enter the first ash setting chamber, then enter the second ash setting chamber through the third control valve, and finally pass through the second dust collector for dust removal. Similarly, when the second dust collector needs to be maintained and overhauled, it is only necessary to cut off the second control valve and open the third control valve to continue to remove the flue gas and / or high-temperature flue gas generated by the second submersible furnace, the second rotary kiln and the second drying kiln. With such a setting, when a dust collector is maintained and overhauled, there is no need to stop production, and dust removal operations can still be performed on the corresponding production line, thereby greatly improving production efficiency.

[0031] See also Figure 1 and Figure 2 The utility model provides an electrostatic precipitator system, comprising a first dust removal production line 1 and a second dust removal production line 2.

[0032] The first dust removal production line 1 includes a first dust settling chamber 11, a first dust collector 12, and a first control valve 13 disposed between the first dust settling chamber 11 and the first dust collector 12 and used to control the communication between the two. In this embodiment, a fourth control valve 14 is further disposed between the first dust settling chamber 11 and the first dust collector 12 for controlling the communication between the two. The first dust settling chamber 11 is provided with a first air inlet 15, and the first dust collector 12 is provided with a first air outlet 16.

The second dust settling chamber 21 is provided with a second air inlet 25, and the second dust collector 22 is provided with a second air outlet 26.

[0034] The first ash settling chamber 11 and the second ash settling chamber 21 are connected to each other through a flue gas pipeline 3, and a third control valve 4 is provided on the flue gas pipeline 3 to control the connection between them;

[0035] In the present invention, a control valve is firstly set between the dust collecting chamber and the dust collector corresponding to each dust removal production line, and then a control valve is set between the dust collecting chambers of adjacent dust removal production lines.

In the actual production process, there may be more than two dust removal production lines arranged side by side, and the dust collection chambers between adjacent dust removal production lines may also be provided with mutually connected flue gas pipes 3 and control valves capable of controlling the connection of the flue gas pipes 3; that is, the layout of more than two dust removal production lines is still within the protection scope of the present invention.
