Alternatively, even if it is insulated from the dust collecting electrode 22, it may be configured to be fixedly installed on a fixed body (not shown) made of an insulator.

However, in terms of maintenance, the discharge electrode 26 may be configured to be easily installed and detached from the above-described fixed body and frames 25 and 25 - 1 . Examples of this are shown in FIGS. 8 to 10 .

First, referring to FIGS. 8 and 9 , the discharge electrode 26 may be specifically configured as a wire-type wire electrode in which one wire or more wires are combined. As a specific configuration, the main line 262 forming a substantial line electrode may be included.

On the other hand, as a configuration including the above-described frame 25 and a fixed body, the dust collecting module 20 may be configured as described above, and the discharge electrode 26 may be installed and detached from the dust collecting module 20 . The configured fixed-side fastening part (concept including the frames 25 and 25 - 1 and the fixed body) may be included in the dust collecting module 20 .

Corresponding to this description, although an embodiment of the structure for installation on the frame 250 is described in FIG. 10 , the same embodiment will be implemented as an embodiment of the structure for installation on the fixture 251 . It should be understood as possible.

Through these various embodiments, the discharge electrode 26 in the form of a wire is fastened to be caught on the fixed side fastening part while being tensioned, and at the same time, the wire is strongly fixed to the first dust collecting electrode 12 by the restoring force due to the elastic force when the fastening is completed. can be In addition, in terms of maintenance such as cleaning, there is an effect that the discharge electrode 26 can be easily separated through a process opposite to the installation process.

Meanwhile, as described above, the dust collecting module 20 includes a dust collecting electrode 22 , a discharge electrode 26 , and insulators 27 and 27-2, etc., which are configured by a front fan in order to perform the function of the present invention.

Of course, in the above configuration, it will be natural that other members may be used according to the coupling structure of the ceiling 100 and each configuration.

As described above, in the dust collecting module 20 , a plurality of cases 210 and 211 are connected to each other as shown in FIG. 1 through the first coupling member 220 . According to this, according to the air dust collection amount per time determined by the air throughput in the tunnel, the air flow amount per unit time in the rear by the operation of the rear fan 30, etc., it is necessary to install a plurality of dust collection modules 20 in groups. in order to be prepared in case there is

In FIG. 1, a plurality of dust collection modules 200 and 201 are illustrated as being modularized so that they are long connected in the air movement direction, but according to the specification of the rear fan 30 inside the tunnel, three-dimensional, that is, x, y, A plurality of modules can be connected/installed to each other along the z-axis.

Meanwhile, in another embodiment of the present invention, the front fan 11 may be additionally installed as shown in FIG. 6 . This is because the air inflow speed may not be sufficiently secured due to the structure of the dust collecting module 20 described above, so that the air moving from the dust collecting module 20 is introduced more strongly from the front to enable smooth processing and circulation of air. For this purpose, the front fan 11 may be installed on the frontmost side of the dust collecting module 20 and the corresponding current collecting module when the group is installed.

As described above, the power supply unit 29 receives external power to generate micro-pulse electric power and supply it to the dust collecting electrode 22 and the discharge electrode 26 .

Specifically, in such a pulsed electrostatic precipitator, a power circuit for generating pulsed power is installed to apply a DC power and a pulsed power to each electrode, and a high voltage pulse is generated from the input voltage to be applied to the discharge electrode and a low voltage is applied at the same time. A power circuit for applying to the dust collecting electrode may be included.

Specifically, it may include a configuration for receiving AC power supply, generating a high voltage through a transformer circuit including a rectifier, and converting the power of the high voltage into a pulse power through a pulse switching device or the like.

Meanwhile, as described above, the tunnel air quality improvement device including the modular plasma electrostatic precipitator according to each embodiment of the present invention removes harmful substances such as dust in the tunnel through the electrostatic precipitation method as described above during general operation. It performs the function, but in the event of a fire, it must perform the function of removing the toxic gas generated by the fire.

To this end, the tunnel air quality improvement apparatus including the modular plasma electrostatic precipitator according to each embodiment of the present invention includes the power supply unit 29 and the rear fan 30 as shown in FIG. 6 , and includes the front fan described above. and a driving control unit 50 for integrally controlling the filter washing module 41 and the like.

At this time, a core function of the driving control unit 50 is to control the driving of the power supply unit 29 and the front fan or the rear fan 30 . That is, in the default state as a state for removing the above-mentioned harmful substances, that is, a general use state in which no fire occurs, the driving control unit 50 drives the power supply unit 29 and the rear fan 30 with a preset first output value. control to perform the dust collection function of hazardous substances in the tunnel.

In this case, the first output value may mean an absolute value or a relative value of power applied to each component from the external power source 70 . For example, a transformer 33 that performs power conversion, etc. to supply power to the rear fan 30, a power supply unit 29 that performs power conversion etc. to supply micro-pulse charge to the dust collection module 20, The same voltage is used in the transformer 13 that performs power conversion, etc. to supply power to the front fan 11 and the transformer 42 that performs power conversion, etc. to supply power to the filter cleaning module 41 In this case, it may mean a corresponding voltage value, or in the case of driving with different driving voltages, it may mean a relative value in which each driving voltage in a default state is set to 1.

On the other hand, when the driving control unit 50 receives a state change input from an external terminal 60 such as a control terminal for managing the tunnel in response to the occurrence of a fire in the tunnel and switches to an emergency state, different from the first output value, Preferably, by controlling the operation of the power supply unit 29, the front fan 11 and/or the rear fan 30 with a preset second output value of a current (voltage) value higher than the first output value, the fire in the tunnel is prevented. Therefore, it is possible to perform the dust collection function of harmful substances in the generated smoke (toxic).

In this case, the second output value has the same concept as the above-described first output value, and may be an absolute value or a relative value according to the driving voltage of each configuration. In this case, in the case of a relative value, it will be understood that when each driving voltage is set to 1 in the default state as described above, it is set to a value greater than the corresponding value.

Meanwhile, a plurality of tunnel air quality improvement devices including a modular plasma electrostatic precipitator may be installed in the tunnel and managed by the above-described external terminal 60 . At this time, the installation location and identification number in the tunnel of the tunnel air quality improving device including each modular plasma electrostatic precipitator are matched and managed in the external terminal 60 for management, so that each of the tunnel air quality improving devices including the modular plasma electrostatic precipitator is managed. The installation location of (E1, E2) and its monitoring can be performed.

In this case, when a fire occurs in the tunnel, the tunnel air quality improvement device including all modular plasma electrostatic precipitators does not need to be switched to the emergency state due to the above-described fire. That is, the external terminal 60 may specify only the tunnel air quality improvement device including the modular plasma electrostatic precipitator to be converted into an emergency state and perform a state change input for requesting the change of the corresponding state.
