High-concentration wastewater treatment device for treating pollutants with strong oxidizing power using plasma
A high-concentration wastewater treatment device includes a discharge pin module including a support plate, discharge pins coupled to the support plate, and pin connectors connected to the discharge pins and extended upwards, a discharge plate module spaced apart from the discharge pins, and a circuit module including a main board, distributed processing boards connected to the main board, coupling unit connecting the distributed processing boards, and discharge pin connection portions electrically connected to the distributed processing boards in a direction of a lower end of the main board. The discharge plate module includes a connection pin connected to a lower end of the support plate and a discharge plate accommodation portion coupled to a lower end of the bent portion. The discharge pin connection portions have, at lower ends, coupling grooves into which the pin connectors are inserted, to allow one-touch coupling between the circuit module and the discharge pin module.
1. A high-concentration wastewater treatment device, comprising:
a discharge pin module including a support plate, multiple discharge pins coupled to the support plate, and pin connectors connected to the multiple discharge pins on the support plate and extending upwards;
a discharge plate module spaced apart from the multiple discharge pins; and
a circuit module including a main board, multiple distributed processing boards connected to the main board, a coupling unit which performs a function of connecting the multiple distributed processing boards, and discharge pin connection portions electrically connected to the distributed processing boards in a direction of a lower end of the main board,
wherein the discharge plate module includes a connection pin connected to a lower end of the support plate and a discharge plate accommodation portion coupled to a lower end of the connection pin; and
the discharge pin connection portions have, at their lower ends, coupling grooves into which the pin connectors are inserted, to allow one-touch coupling between the circuit module and the discharge pin module.
2. The high-concentration wastewater treatment device according to claim 1 , further comprising:
a discharge plate slidably coupled to an inside of the discharge plate module.
3. The high-concentration wastewater treatment device according to claim 1 , further comprising:
a support structure positioned below the circuit module,
wherein the support structure includes a bottom plate, a sidewall extended from the bottom plate, and a flange extended outwards from above the sidewall, and provides an internal space accommodating the discharge pin module and the discharge plate module; and
when the flange is coupled to the sidewall through a flange protrusion, the discharge plate, which is slidably coupled to the discharge plate module, can be drawn through the flange through-hole.
4. The high-concentration wastewater treatment device according to claim 1 , wherein the discharge plate has multiple through-holes, each corresponding to one of the multiple discharge pins.
5. The high-concentration wastewater treatment device according to claim 1 , wherein the pin connector includes a lower connection plate connected to the multiple discharge pins on an upper surface of the support plate and an upper connection plate extending upwards from an end of the lower connection plate, and the upper connection plate has a support connection plate extending upwards from an end of the lower connection plate and a coupling connection plate having a smaller width than the support connection plate and extending upwards.
