Embodiment 1

[0016] Embodiment 1 This embodiment discloses a method for preventing spontaneous combustion of coal in a strip coal storage yard. The method is as follows:

[0017] Carry out several partitions along the length range of the strip-shaped coal storage yard, and the number of partitions is not less than one; then lay a pipeline (DN80 steel pipe, which has been treated with anti-corrosion before use) along the length range of the strip-shaped coal storage yard, as the first steam main pipeline; in each partition, two side main pipelines (DN40, which have been subjected to anti-corrosion treatment before use) that are parallel to each other and run through the bottom of the strip-shaped coal storage yard are led out on the first main pipeline; Between the side main pipes, a considerable number of branch pipes parallel to each other and perpendicular to the two side main pipes (DN25 steel pipes have been carried out with anti-corrosion treatment before use); The branch pipes commun...

Abstract

The invention belongs to the technical field of coal storage, in particular to a method for preventing spontaneous combustion of coal in a strip-shaped coal storage yard and the application of the method. The method comprises the steps that a first main pipeline is laid along the long edges of the bottom of the strip-shaped coal storage yard, and at least one pair of lateral main pipelines are arranged on one side of the first main pipeline; and then steam is evenly introduced into the coal storage yard from the initial end of the first main pipeline, and the steam is delivered to the bottom of the strip-shaped coal storage yard through the first main pipeline and the lateral main pipelines. The steam is introduced into the coal storage yard according to specific parameters and methods, so that it is guaranteed that sufficient moisture is contained in the coal, the temperature of a coal pile is stable, spontaneous combustion of the coal is avoided after the coal is stored for a long time, and the problem of spontaneous combustion is completely solved; the method has extremely broad market prospects and economic value.

Description

technical field [0001] The invention belongs to the technical field of coal storage, and in particular relates to a method for preventing spontaneous combustion of coal in strip coal storage yards and an application thereof. Background technique [0002] The strip coal yard is unable to be fully stacked and taken out first, so there is a certain phenomenon of spontaneous combustion, which is a common problem at present. At present, the methods to solve the spontaneous combustion of strip coal yards are: layered compaction, regular replacement, and mechanical removal. The specific measures are: in the coal storage area, all combustible debris that is easy to catch fire, such as wood chips, paper, linoleum, oil-soaked rags and flammable chemicals, etc. should be removed; the coal storage site should be dried , should not pile up slag, dry coal powder or other porous substances, the floor should have a certain slope, and the coal pile should be compacted in layers to isolate t...
