Abstract
The invention discloses a mobile cooling refrigeration device for a mine, which comprises an efficient axial flow fan, an evaporator, an electrical control system, a screw compressor, a frame, a shell, a connecting pipeline, a condenser and a cooling water circulation system. The screw compressor, the evaporator, the electrical control system and the condenser are respectively fixed in the frame, the efficient axial flow fan is connected with an air inlet of the evaporator via a soft connector, the shell is mounted outside the frame, and the screw compressor, the condenser and the cooling water circulation system are connected via the connecting pipeline. The mobile cooling refrigeration device for the mine realizes transmission and transfer of thermal energy via a vaporization process and a liquefaction process of refrigerant. The thermal energy on a working surface is continuously transferred to a recooler of a return aircourse via circulation water flow, finally, heat dissipation is finished via air return flow of the return aircourse and spraying of a spraying pump, the temperature of local air in the mine is reduced, and safety of operation under the mine is facilitated.
Description
Technical field
The present invention relates to a kind of mine and move the cooling refrigerating plant.
Background technology
The colliery is one of main energy sources of China, and along with the development of society and the reinforcement day by day of coal resources exploitation, the mining depth of mine constantly increases; At present; Each country of mainly mining of the world gets into deep mining in succession, the progressively increase of mining depth, and ground temperature also increases; According to survey data all over the world, global mean ground temperature gradient is about 3 ℃/100m, according to national mine elevated temperature heat evil reconnaissance information statistics; Heat evil has in various degree appearred in the existing at present 65 pairs of mines of China, and wherein the getting working face temperature of 38 pairs of mines surpasses 30 ℃, according to China's coalfield ground temperature measurement statistics; Hundred meter temperature gradients are 2-4 ℃/100m, and regulation is made to downhole temperature in countries in the world, and on January 1st, 2005 was played new " safety regulations in coal mine " regulation of enforcement in by China; Mine main getting working face air themperature must not be above 26 ℃; The air themperature of electromechanical equipment chamber must not surpass 30 ℃, and under the deep mining condition, ground temperature constantly raises; The harm of heat evil and toxic and harmful, dust also increases day by day; These harm have a strong impact on the efficient of operating worker and their physical and mental health, even cause the generation of some mine serious accidents probably, have brought great threat for the safety in production and the daily management thereof of mine; It is thus clear that the coal mine deep well falling temperature technique is just becoming a key areas of domestic and international mine study-a.
Summary of the invention
The purpose of this invention is to provide a kind of mine and move the cooling refrigerating plant.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of mine moves the cooling refrigerating plant; Comprise efficient axial flow blower, evaporimeter, electrical apparatus control system, helical-lobe compressor, framework, housing, connecting line, condensing apparatus and cooling water recirculation system; Said helical-lobe compressor, evaporimeter, electrical apparatus control system and condensing apparatus are separately fixed in the framework; Said efficient axial flow blower links to each other with the evaporimeter air intake through being flexible coupling; Housing is installed in outside the framework, and said helical-lobe compressor, condensing apparatus and cooling water recirculation system link to each other through connecting line.
Said cooling water recirculation system comprises back cooler, blower fan, water filter and water pump, and said time cooler, blower fan, water filter and water pump are connected through pipeline.
