Large-scale centralized preparation system for pulverized coal and distribution method

Abstract

The invention discloses a large-scale centralized preparation system for pulverized coal and a distribution method. In the invention, raw coal is dried in a drying system by virtue of heat energy from a power generation enterprise in a raw coal producing area; dried coal briquettes are input into a grinding system so as to be processed into qualified pulverized coal; then the qualified pulverized coal is conveyed to coal-based power enterprises and other pulverized coal users for use by means of conveying equipment; and the whole pulverized coal processing and transportation process is in an inert environment so as to ensure the safe operation of the whole system. The large-scale centralized preparation system and the distribution method are mainly applied to large-scale centralized pulverized coal manufacturing factories in mining areas, wherein the factories provide the pulverized coal for the coal-based power enterprises and other pulverized coal users by a mode of conveying the qualified pulverized coal.

Description

Technical field: [0001] The invention belongs to the field of coal power, and relates to a safe and efficient large-scale pulverized coal centralized preparation system and distribution method, in particular to an efficient and clean large-scale pulverized coal preparation system and distribution method. Background technique: [0002] The power industry occupies an important position in my country's national economy and is an important guarantee for the stable operation and sustainable development of my country's social economy. As an important energy industry in my country, power industry enterprises are duty-bound to save energy, reduce emissions, and achieve low-carbon development. my country's energy structure of "rich in coal, poor in oil, and low in gas" determines that coal power will remain the main force of my country's power production for a considerable period of time in the future. By the end of 2010, the national power generation equipment capacity was 962.19 m...

Problems solved by technology

[0015] The centralized pulverization system in foreign countries is still limited to the interior of coal power enterprises. The transportation of raw coal is inevitable. Coal power enterprises must also build raw coal yards and huge pulverization systems. Dust pollution and noise pollution in the enterprise cannot be avoided.

[0016] The domestic Coal Research Institute has conducted some research on the pulverization system, and published the patent "A Coal Powder Preparation System and Process". The coal powder preparation system is an independent coal powder preparation system, including a crushing system, a drying system and Grinding system, which mainly focuses on the preparation process of pulverized coal, is limited to pulverization in front of industrial pulverized coal furnaces, and does not consider the safety issues in the process of pulverized coal preparation and transportation, although the patent mentions the need to transport pulverized coal outside problem, but did not consider it in detail
