Abstract
The invention discloses an application method of non-reburning fire extinguishing charcoal, relating to the technical field of coal fire extinguishing, which comprises the following specific application steps: step one, fully spraying magnesium hydroxide solution on burning coal; step two, heating the magnesium hydroxide solution at a high temperature of 340-450 ℃ to form a white protective layer on the surface of coal, wherein the protective layer is magnesium oxide; step three, the coal can be extinguished, and the magnesium oxide protective layer can resist high temperature, so that the coal can be fully prevented from reburning. The invention relates to an application method of fire-extinguishing charcoal without reburning, which is mainly used for fire extinguishing of coal, has simple manufacturing method and economic manufacturing cost, can quickly realize fire extinguishing of coal, and can ensure that the coal cannot reburn subsequently.
Description
Technical Field
The invention relates to the technical field of coal fire extinguishing, in particular to an application method of fire extinguishing charcoal without reburning.
Background
Coal is one of the main energy sources in China, and is commonly found in our daily life. Once coal causes fire, the released heat is large, the temperature is high, the coal cannot be extinguished by only depending on water, the cost of the special extinguishing agent is too high, and the coal has the risk of reburning.
Disclosure of Invention
The invention provides an application method of fire extinguishing charcoal without reburning, which aims to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
an application method of fire extinguishing charcoal without reburning is characterized in that: the specific application steps of the non-reburning fire extinguishing charcoal are as follows:
step one, fully spraying magnesium hydroxide solution on burning coal;
step two, after the magnesium hydroxide solution is heated at the high temperature of 340-450 ℃, a white protective layer is formed on the surface of the coal, and the protective layer is magnesium oxide;
and step three, the coal can be extinguished, and the magnesium oxide protective layer can resist high temperature, so that the coal can be fully prevented from reburning.
Preferably, the concentration of the magnesium hydroxide solution in the first step is higher than 5%.
Preferably, the magnesium oxide protective layer in the third step can resist 2852 ℃, and the temperature can hardly be reached in daily environment.
Compared with the prior art, the invention has the beneficial effects that:
the invention relates to an application method of fire-extinguishing charcoal without reburning, which is mainly used for fire extinguishing of coal, has simple manufacturing method and economic manufacturing cost, can quickly realize fire extinguishing of coal, and can ensure that the coal cannot reburn subsequently.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
Referring to fig. 1, the present invention provides a technical solution:
an application method of fire extinguishing charcoal without reburning is characterized in that: the specific application steps of the non-reburning fire extinguishing charcoal are as follows:
step one, fully spraying magnesium hydroxide solution with the concentration higher than 5% on burning coal;
step two, after the magnesium hydroxide solution is heated at the high temperature of 340-450 ℃, a white protective layer is formed on the surface of the coal, and the protective layer is magnesium oxide;
and step three, the coal can be extinguished, and the magnesium oxide protective layer can resist the high temperature of 2852 ℃, which can not be achieved in daily environment, so that the coal can be fully prevented from reburning.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
