Constant-temperature cold conveying system of underground movable-type escape capsule and refuge chamber

Abstract

The invention discloses a constant-temperature cold conveying system of an underground movable-type escape capsule and a refuge chamber, and the constant-temperature cold conveying system comprises an explosion-proof refrigerating unit and a constant-temperature cold conveying device, wherein the constant-temperature cold conveying device comprises a main ice storage box, an auxiliary ice storage box, a low-temperature heat pipe, a fin, an air inlet passage, an air return passage, a vertical connecting air pipe, an explosion-proof fan and built-in coil pipes, the main ice storage box is fixedly arranged on the lower side of the auxiliary ice storage box, the built-in coil pipes which are mutually communicated with one another are distributed inside the main and the auxiliary ice storage boxes in a Z shape, the built-in coil pipes inside the main ice storage box and the auxiliary ice storage box are connected to the explosion-proof refrigerating unit through connecting pipes, the inner bottom side of the main ice storage box is provided with the air return passage, an air blowing passage is arranged inside the auxiliary ice storage box, the air return passage and the air blowing passage are communicated with each other through the vertical connecting air pipe, the fin and the low-temperature heat pipe are fixedly arranged inside the air blowing passage, the fin is arranged on the low-temperature heat pipe, the tail end of the low-temperature heat pipe extends to the bottom of the main ice storage box, and the explosion-proof fan is installed on an outlet of the air blowing passage.

Description

technical field [0001] The invention relates to the field of safety equipment and air conditioning and refrigeration, in particular to a constant temperature and cooling system for underground movable rescue cabins and refuge chambers. Background technique [0002] my country is a big coal-producing country, a country heavily dependent on coal energy, and also a big country with air accidents. With the continuous increase of coal mining depth, the danger of coal mine outburst is also becoming more and more serious. According to statistics, my country's coal production accounts for 35% of the world's total, but the number of deaths in mining accidents accounts for 80% of the world's total. The death rate per million tons in my country is close to 4%, which is 100 times that of the United States and 30 times that of South Africa. The safety situation of coal mines in my country increasingly severe. When unavoidable mine disasters occur, there is a special need for a device th...
