Description
Technical field
The invention belongs to save, heat recovery technology field, a kind of more particularly to finned tube cooling water steam heat recovery system,
Recycling available for mining and metallurgy waste heat.
Background technology
The industrial energy consumption in China accounts for the 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, about half of heat passes through cooling water
It is directly discharged in air, has both wasted substantial amounts of heat energy, caused environmental pollution again.Because cooling water typical temperature is relatively low, typically
Less 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.With
The increasingly mature of heat pump techniques, turns into a new method of waste heat recovery using heat pump recovery waste heat.
Existing cooling water waste heat recovering system is mainly directly exchanged heat using heat transmission equipment.It is direct with heat transmission equipment
The process program to be exchanged heat increases waste heat time in the case where the original cooling system of reservation is constant in original cooling system
Receipts system.The capital equipment of original cooling system includes circulating pump, heat exchanger, cooling system, control system and pipeline etc..Its energy
The transmittance process of amount：The equipment of required cooling-heat-source Cycles water-heat exchanger-recirculated water to be heated.The main of this system lacks
Point：From the operation principle of heat exchanger, during heat exchanger is exchanged heat, the temperature of heat recirculated water to be added is necessarily less than
The temperature of heat source water.The temperature of recirculated water to be heated can be lower if the temperature of heat source water is not high, along with transmitting procedure
In thermal loss, the temperature of water can become lower, and value is not high, waste heat recovery of this scheme in industrial colling
The occasion that can be directly utilized in journey is very limited.
Domestic metallurgy industry is power consumption rich and influential family, the main electricity consumption alloy smelting of mineral hot furnace, in-furnace temperature up to more than 1300 DEG C,
To avoid electric furnace body from burning molten, it is necessary to which substantial amounts of body cooling water is electric furnace cooling.At present in metallurgical submerged-arc furnace, for control electricity
Furnace temperature is stable, frequently with water cooling system.The system includes ore-smelting electric furnace, cooling tower and water circulating pump.It is cold in conventional system
But water is fed directly in cooling tower, and delivering to ore-smelting electric furnace by water circulating pump again after being cooled using cooling tower is recycled.
The problem of existing during this be：The electric furnace cooling water exported by sofening treatment from mineral hot furnace carries certain temperature and pressure
Power, itself contain substantial amounts of energy, but be difficult to be utilized because grade is not high, can only be handled, handled by cooling tower cooling
These cooling waters can also produce some water consumes and power consumption, therefore the problem of energy waste be present.
Electric arc furnaces cooling water system original adoption single flow is Direct Discharging Type Cooling Water System, in Direct Discharging Type Cooling Water System
In, cooling water is such a method small investment, easy to operate only by being just discharged after needing cooling-part once, but its water quality
It is difficult to ensure that, water consumption is big, and operating cost is high, it is impossible to meets requirement of the technique to water quality, does not also meet current energy-conserving and environment-protective
Medicine look forward to, with national regulatory strengthen and process aspect to water quality more stringent requirement, single flow cooling water mode and by
Gradually it is eliminated.
