Rapid packagingmethod for preventing spontaneous combustion of pulverized coal

Abstract

The invention discloses a rapid packaging system and method for preventing spontaneous combustion of pulverized coal. The packaging system comprises a sealed vacuum chamber. A packaging mechanism is arranged in the vacuum chamber. A pulverized coal discharge opening is formed in the upper portion of the packaging mechanism. A conveying mechanism is arranged on the lower portion of the packaging mechanism. The vacuum chamber is respectively connected with a vacuum pump and a vacuum meter. The packaging mechanism comprises a discharge bag connected with the discharge opening. A discharge bag is sleeved on the discharge opening and arranged on a discharge measurement scale connected with a control mechanism. The packaging method includes the steps that stopping agents are added to the pulverized coal from the upper end of the discharge opening at a certain ratio, the stopping agents and the pulverized coal are evenly stirred by a stirring system device, the vacuum pump is started in the packaging process of the pulverized coal, and the pulverized coal is conveyed to a pulverized coal bin after being packaged in a negative pressure mode. The stopping agents are added to the pulverized coal and then the pulverized coal is packaged in a negative pressure mode, so that the effect of dually preventing the spontaneous combustion of the pulverized coal is achieved, the coal-oxide compound effect is effectively prevented, consumption of the stopping agents is greatly reduced, anti-inflaming cost is reduced, and the problem that the pulverized coal is low in packaging speed is solved.

Description

technical field [0001] The invention relates to a rapid packaging method for preventing spontaneous combustion of pulverized coal, in particular to a rapid packaging system and method for preventing spontaneous combustion of pulverized coal suitable for the coal industry. technical background [0002] As the pillar industry of energy in our country, the transportation problem of coal is very prominent. With the increase of coal mining mechanization, the transportation ratio of fine coal increases, and the popularization of coal-water slurry combustion technology before the furnace makes the transportation of pulverized coal more and more frequent. Any kind of coal exposed to the air has a variety of functions and has the property of spontaneously generating heat. The spontaneous combustion of coal has always plagued the safety production of coal mines in my country, causing great waste of resources and serious environmental pollution problems, endangering human health. and l...

Problems solved by technology

The pulverized coal has a certain temperature when it is packaged out of the warehouse, which accelerates the recombination of coal and oxygen to a certain extent, resulting in the continuous accumulation of heat and forming a fire hazard.

In addition, pulverized coal has a small particle size, light specific gravity, and is easy to fly. In the packaging process of pulverized coal, there is a problem of extremely slow feeding, which seriously affects the industrial continuous production process of pulverized coal.
