Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Depend on figure 1 Shown is a device that uses magnesium hydroxide nanoparticles to suppress the flammability of Shenfu coal. The specific embodiment: a coal feeding port 1 is installed on the upper right of the adsorption furnace 2, and the inner wall of the furnace wall of the adsorption furnace 2 is respectively fixed. There are a first-level left slant plate 3, a first-level right slant plate 4, a second-level left slant plate 5 and a second-level right slant plate 6. Coal particles 21 are placed on these inclined plates. A coal outlet 7 is provided on the adsorption furnace 2 near the secondary right inclined plate 6 . A primary air inlet pipe 8 and a secondary air inlet pipe 9 are installed below the adsorption furnace 2 , and they are all installed above the main air inlet pipe 22 . A primary air intake valve 15 is installed on the pri...

Abstract

The invention relates to a device for inhibiting inflammability of Shenfu coal by adopting magnesium hydroxide nanoparticles. According to the device, porous inclined plates arranged in a staggered manner are arranged in an adsorption furnace, so that coal granules slide along the inclined plates, and retention time of the coal granules in the adsorption furnace is prolonged. Meanwhile, after airis preheated to a certain temperature by adopting an air heater, the magnesium hydroxide nanoparticles are mixed with hot air under vacuum take-off of a venturi tube and then fed into the adsorption furnace. When hot airflow and the coal granules are mutually contacted to be dehydrated so as to form air gaps, the nanoparticles are adsorbed into the pores of the coal granules, so that a spontaneousignition point of the Shenfu coal is improved so as to inhibit the inflammability, and the coal can be conveniently and safely stored for a long time. The device is low in cost, energy-saving, environmental-friendly, compact in structure, safe and reliable.

Description

1. Technical field [0001] The invention belongs to the field of coal chemical application technology, and in particular relates to a device for suppressing the flammability of Shenfu coal by using magnesium hydroxide nanoparticles. 2. Background technology [0002] Oxidation and spontaneous combustion of coal is not only a major accident hazard, but also reduces the economic value of coal. Long-term accumulation of coal will increase the ash content in coal due to oxidation, decrease the fixed carbon and calorific value, and reduce the quality of coal. Coal spontaneous combustion can also cause a large amount of coal to be burned in vain. For example, the bituminous coal burned by Shantou Power Plant often has more than three months of normal consumption in the coal factory. Due to the long storage time of the coal, spontaneous combustion often occurs, and sometimes spontaneous combustion occurs in several places at the same time. Spontaneous coal is sent to conveying and ...
