Coal pile temperature measuring and cooling grouting device and system

Abstract

The invention discloses a coal pile temperature measuring and cooling grouting device. The coal pile temperature measuring and cooling grouting device comprises an outer-layer inverted circular truncated cone body, an inner-layer inverted circular truncated cone body and self-heat-transfer heat pipes; the inner-layer inverted circular truncated cone body is connected with the outer-layer invertedcircular truncated cone body through bayonets; the top of the outer-layer inverted circular truncated cone body is of an open structure; the bottom of the outer-layer inverted circular truncated conebody is provided with an outer-layer circular truncated cone body bottom plate; the top of the inner-layer inverted circular truncated cone body is provided with an inner-layer inverted circular truncated cone body top plate; the bottom of the inner-layer inverted circular truncated cone body is provided with an inner-layer inverted circular truncated cone body bottom plate; the lower ends of theself-heat-transfer heat pipes penetrate through the inner-layer inverted circular truncated cone body top plate and extend into the middle-lower part of the inner-layer inverted circular truncated cone body; fins are arranged on the outer side wall of the outer-layer inverted circular truncated cone body; the fins are provided with a plurality of thermocouples; a plurality of outer-layer invertedcircular truncated cone body grout outlets are formed in the outer-layer inverted circular truncated cone body; a plurality of inner-layer inverted circular truncated cone body grout outlets are formed in the inner-layer inverted circular truncated cone body; and the inner-layer inverted circular truncated cone body is provided with a grouting system. The invention further discloses a coal pile temperature measuring and cooling grouting system. With the coal pile temperature measuring and cooling grouting device and system of the invention adopted, the temperature of a coal pile can be monitored in real time, the coal pile can be cooled through the self-heat-transfer heat pipes; the coal pile can be accurately cooled through grouting; and a cooling effect is good.

Description

technical field [0001] The invention belongs to the technical field of preventing spontaneous combustion of coal piles, and in particular relates to a coal pile temperature measuring and cooling grouting device and system. Background technique [0002] my country is rich in coal resources, and there is a great demand for coal in coal mines, large chemical companies, steel plants, thermal power companies, cement plants, coking plants, metallurgical plants, etc. Spontaneous combustion of coal piles occurred, causing massive property losses. Therefore, it is necessary to monitor the temperature of the coal pile and take cooling measures when the temperature of the coal pile is too high. [0003] The phenomenon of spontaneous combustion of coal piles is due to the oxidation of coal in contact with air and the release of heat. The excessive accumulation of coal leads to the inability to dissipate the heat generated by oxidation in time, which gradually increases the temperature o...

AI Technical Summary

Problems solved by technology

Spraying the surface of the coal pile with water directly or digging trenches for irrigation will make the amount of water infiltrated into the coal pile uneven and easy to lose, and it is easy to wash away the coal or soak the wall

Due to the small amount of water entering the spontaneous combustion part under the action of heat and pressure, the fire prevention effect is not good
