Description

Technical Field

[0001] The invention relates to the field of coal-fired power plants, and in particular to a compact, slightly negative pressure coal yard, efficient and environmentally friendly coal-fired power plant structure. Background Art

[0002] A coal-fired power plant, also known as a thermal power plant, is a factory that uses combustibles such as coal as fuel to produce electricity. In order to ensure effective use of space in a thermal power plant, various settings will be installed more compactly. In order to protect the environment of the factory, fans will also be installed to maintain a slight negative pressure in the workshop, so that internal dust is not easily retained during processing in the workshop.

[0003] According to the Chinese patent with patent number CN202021944304.0, a compact, micro-negative pressure coal yard, high-efficiency and environmentally friendly coal-fired power plant structure is disclosed. By arranging a fan room, a cable protection pipe and a fire fighting room, the fan room can improve the air inside the plant area, and the cables for outputting electric energy can be passed through the cable protection pipe. The cable protection pipe can protect the cables. The insulating layer on the inside of the cable protection pipe can improve the insulation effect of the cable protection pipe to avoid conductivity. The thermal insulation protective layer on the outside of the cable protection pipe can play an insulating role to prevent external heat from entering the cable protection pipe and heating the cables. The fire fighting room is located on one side of the coal storage bin, close to the workshop and the coal storage bin. When a fire occurs, rescue can be carried out quickly.

[0004] With regard to the above-mentioned related technologies, the inventors believe that when the above-mentioned coal-fired power plant is used, since coal-fired power generation will produce dust, ash and harmful gases, dust removal through a simple fan room is not safe and environmentally friendly. At the same time, the fire fighting room provided therein can only play a role when a fire occurs, but cannot effectively prevent the occurrence of a fire. At the same time, the above-mentioned plant area has only one entrance and exit, which makes it easy for a large number of people in the workshop to be crowded or even trampled when a fire or other disaster occurs, making the plant area unsafe. Summary of the invention
