A preparation system and method for phase change material temperature-controlled cell-coating inhibitor

Abstract

The invention discloses a phase-change material temperature-control coating retarder preparation system and a method thereof. A retarder solution sequentially passes through an ice ball preparation unit, a downward leakage unit, a phase-change material fusing unit, a spraying unit, a cooling unit and a screening unit and then is prepared into a temperature-control coating retarder wrapped with a phase-change material, the adhesion effect of the phase-change material can be controlled when ice ball particles passes through a spraying zone, and namely, the final coating thickness is controlled. The phase-change material is used as the coating material, a layer of phase-change material can wrap a high-water-content composite retarder to serve as a coating, not only is the defect that traditional fire preventing and extinguishing retarders are prone to failure overcome, but also the phase-change material temperature-control coating retarder is sensitive to temperature rising and can be melted before the natural critical temperature of coal reaches, and accordingly, the retarder in the coating is released to inhibit coal spontaneous combustion; and the preparation system is designed in a modularized mode, the structure is simple, operation is easy, and the coating retarder can be produced and processed efficiently.

Description

technical field [0001] The invention relates to a preparation system and method for an inhibitor, in particular to a preparation system and method for a phase change material temperature-controlled cell coat inhibitor. Background technique [0002] my country is not only the country with the largest coal production in the world, but also one of the countries with the most serious spontaneous combustion of coal seams. Coal mine fires are one of the major disasters that threaten the safe production of coal mines in my country. With the vigorous promotion of high-yield and high-efficiency technologies for fully mechanized top coal caving in extra-thick layers, coal spontaneous combustion fires in goafs frequently occur in mines, and spontaneous combustion can easily cause gas combustion and explosions. Inhibitor prevention and control of coal spontaneous combustion technology is currently a commonly used fire prevention technology, but the inhibitor has shortcomings such as sho...
