Description
Technical field
The utility model belongs to energy-conservation, heat recovery technology field, particularly relates to a kind of finned tube cooling water steam heat recovery system, can be used for the recycling of mining and metallurgy waste heat.
Background technology
The industrial energy consumption of China accounts for 62% ~ 70% of total energy consumption, and wherein cooling water recirculation system energy consumption can account for the half of industrial production energy consumption.The efficiency of energy utilization only 30% ~ 40% of industry, the heat of nearly half is directly discharged in air by cooling water, has both wasted a large amount of heat energy, has caused environmental pollution again.Because cooling water typical temperature is lower, generally lower than 35 DEG C, belong to low-grade heat source, the occasion that can directly utilize is few, and this brings certain difficulty to waste heat recovery.Increasingly mature along with heat pump techniques, utilizes heat pump recovery waste heat to become the new method of of waste heat recovery.
