Description

Electric Precipitator for Ship}

The present invention relates to an electric dust collector for a ship, and more particularly, to an electric dust collector for a ship that is easy to maintain by opening the side of the electric dust collector housing and allowing the electrode plate and the dust collector to be detached through the open side.

In general, exhaust gas emitted from ships includes PM (Particulate Matter), dust, and fine dust (hereinafter, collectively referred to as "PM"). These are representative air pollutants that are subject to emission regulations from the Organization.

In particular, since ships use HFO (Heavy Fuel Oil), a low-grade raw material with high viscosity, low volatility, and low flammability, to reduce fuel costs, PM is generated more than other transportation means due to incomplete combustion. .

Since these PMs are usually very small, such as a few micrometers in size, they are moved while floating in the air, and they are adsorbed on the hull or facilities provided on the hull, impairing the aesthetics and adversely affecting the marine ecosystem or people.

In order to solve this problem, an electric dust collector is applied to a ship, which is disposed on a flow path through which air flows and collects contaminants such as dust contained in the air.

However, due to the nature of the electric dust collector, if it is used for a long period of time, the dust collecting plate and the discharge electrode are contaminated by dust, so periodic replacement work is required.

The conventional electrostatic precipitator is provided to open the upper part, so it takes a lot of manpower and work time to open the upper part and draw out and draw in the dust collecting plate and the discharge electrode through the open upper part. Since it has to be separated, there is a problem of low economic efficiency, such as requiring a lot of work time and cost.

The stud bolt and the fastening pin are screwed to each other, and the stud bolt is a member having screw surfaces formed on outer periphery of both ends, and the fastening pin is a member having screw surfaces formed on the inner periphery of both ends.

That is, a plurality of the electrode plate and the dust collecting plate are coupled to each other to cross each other by a fastening member, and are arranged to be spaced apart from each other by a predetermined distance by the length of the fastening pin.

In addition, the guide ring 229 is formed in a ring shape and is mounted on the outer periphery of the stud bolt, and is an element for guiding the vertical movement of the stud bolt inside the slot hole (H).

That is, since the stud bolt can be raised and lowered and rotated at a predetermined angle inside the slot hole, it is provided so as to respond to the length change of the electrode plate and the dust collecting plate while maintaining the fastening with the fastening pin by the length of the slot hole.

In addition, since the electrode plate and the dust collecting plate of the present invention are mutually fastened by a fastening member, the operator can adjust the size (width) of the electrode cell 220 by adjusting the number of the electrode plate and the dust collecting plate according to the size of the housing 100 . have.

In addition, when maintenance of a specific electrode plate and dust collecting plate is required, the operator only needs to replace the corresponding electrode plate and dust collecting plate, so the maintenance of the product is easy.

Then, the voltage applying plate 240 is coupled to the front and rear of the electrode cell 220, respectively.

An electrode is provided on one surface of the voltage applying plate 240 , and the voltage applying plate is an element for applying a voltage to the electrode plate 222 of the electrode cell 220 .
