Description

Indoor low carbon loading and unloading machine dust reduction atomization system {INDOOR LOW CARBON TOP AND BOTTOM WEIGHT DUST REDUCTION ATOMIZATION SYSTEM}

The disclosed subject matter relates to a system for suppressing coal dust for indoor coal storage, and more particularly, to a system for suppressing coal dust generation of coal.

Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

In general, in an outdoor coal plant such as a thermal power plant, coal is transported using a conveyor, and a number of conveyors are connected in series according to the transport path of the coal and the length of the conveyor. At this time, the neighboring conveyors are connected with a height difference between them so that the coal transported along the upstream conveyor falls on the downstream conveyor and transports. Coal contains dust having a very small particle size, and such dust is scattered into the atmosphere during the transportation of the coal, and is more severely scattered into the atmosphere by the impact energy generated when it falls on the downstream conveyor. Since dust causes respiratory disorders in the human body and contains carcinogens, a separate dust removal device for removing dust is installed in coal plants, for example, in thermal power plants.

The filter type dust collector is mainly used as the dust removal device. This filter type dust collector removes dust using a porous filter net. It can remove dust in a dry state with a certain particle size or more, but coal dust is Since it contains a large amount of moisture, clogging of the filter net occurs, which causes an increase in the required power cost, and maintenance cost increases by frequently cleaning or replacing the filter net to solve this problem.

Meanwhile, recently newly established coal-fired power plants such as Samcheok, Dangjin, Taean, Boryeong, and Bukpyeong and new coal-fired power plants such as Goseong and Gangneung have installed indoor storage sites to primarily reduce coal dust scattered into the atmosphere. By installing sprays in multiple places inside the indoor coalyard to spray water, the coal dust generated from the conveyor and coalyard was secondarily reduced, and fire was prevented, but because water particles larger than the size of the dust particles are sprayed. The effect of reducing dust was insignificant, and there was a problem that wastewater was generated.

In addition, since the area where water is sprayed by the spray is narrow and the spray distance is limited, a large amount of spray is installed in order to cover a wide indoor storage area. In the process of spraying water through such spray, the amount of water used is reduced. There was an increasing problem.

On the other hand, there is a patent registration No. 10-1247180 as a spray device for preventing dust for low coal loading. This patent is a method of spraying water particles using a blower, and there is a concern of explosion of coal dust due to heat generated from the blower, and there is a problem of dust ash scattering due to the blower, and structural reinforcement of the support device for the system configuration There was a problem in that the cost for the construction of the electrical and control cables was excessively generated.
