Description

A kind of recuperation of heat of cooling pond utilizes system
Technical field
The utility model belongs to energy-conservation, heat recovery technology field, the recuperation of heat that relates in particular to a kind of cooling pond utilizes 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 atmosphere by cooling water, has both wasted a large amount of heat energy, causes again environmental pollution.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 a new method of waste heat recovery.
Existing cooling water waste heat recovering system is mainly to utilize heat transmission equipment (as heat exchanger) directly to carry out heat exchange.Directly carry out the process program of heat exchange with heat transmission equipment (as heat exchanger) in the situation that the original cooling system of reservation is constant, in original cooling system, increase residual neat recovering system.The capital equipment of original cooling system comprises circulating pump, heat exchanger, cooling system, control system and pipeline etc.The transmittance process of its energy: required cooling equipment---heat-source Cycles water---heat exchanger---recirculated water to be heated.The major defect of this system: from the operation principle of heat exchanger, carry out in the process of heat exchange at heat exchanger, the temperature of recirculated water to be heated is necessarily less than the temperature of heat source water.If the temperature of heat source water is not high, the temperature of recirculated water to be heated can be lower, add the thermal loss in transmitting procedure, it is lower that the temperature of water can become, and value is not high, and the occasion that this scheme can directly be utilized in the waste heat recovery process of industrial colling is very limited.
Domestic metallurgy industry is power consumption rich and influential family, the main electricity consumption alloy smelting of mineral hot furnace, and in stove, temperature can reach more than 1300 DEG C, molten for avoiding electric furnace body to burn, and needing a large amount of body cooling waters is electric furnace cooling.In metallurgical submerged-arc furnace, stable for controlling furnace temperature at present, often adopt water cooling system.This system comprises ore-smelting electric furnace, cooling tower and water circulating pump.In conventional system, cooling water is directly delivered in cooling tower, utilizes to deliver to ore-smelting electric furnace by water circulating pump again after cooling tower cooling and recycle.The problem existing in this process is: carried certain temperature and pressure through softening processing from the electric furnace cooling water of mineral hot furnace output, itself containing a large amount of energy, but due to grade not high being difficult to be utilized, can only be by the cooling tower processing of lowering the temperature, process these cooling waters and also can produce some water consumption and power consumptions, therefore have the problem of energy waste.
Electric arc furnaces cooling water system original adoption single flow is Direct Discharging Type Cooling Water System, in Direct Discharging Type Cooling Water System, cooling water has only just been discharged after needing cooling-part once, this kind of method small investment, easy and simple to handle, but its water quality is difficult to ensure, water consumption is large, operating cost is high, can not meet the requirement of technique to water quality, do not meet the medicine enterprise of current energy-conserving and environment-protective yet, along with national control reinforcement and process aspect are to the more and more stricter requirement of water quality, single flow cooling water mode and being eliminated gradually.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of recuperation of heat of cooling pond to utilize system.This system is utilized thermal power transfer principle, by the waste heat recovery of the cooling water of the cooling water of electric furnace and scum, again utilizes.
The recuperation of heat of cooling pond utilizes a system, comprises Recovery of the hot water machine, circulating box, calandria heat exchanger, storage softened water tank.Described Recovery of the hot water machine, by pipeline connecting electrode cooling pond, receives the thermal water source that described cooling of electrode pond provides.Described Recovery of the hot water machine connects scum cooling pond by pipeline, receives the thermal water source that described scum cooling pond provides.Described calandria heat exchanger is arranged on the top of described scum cooling pond, and connects described Recovery of the hot water machine by pipeline.Hot water generation heat exchange in high-temperature steam and calandria heat exchanger that scum cooling pond produces, has further improved the temperature from the hot water in Recovery of the hot water machine.Hot water through heat exchange returns in Recovery of the hot water machine, thereby has reached the recuperation of heat utilization of vapor portion.
In described circulating box, be provided with that to add thermoelectricity auxiliary, in described circulating box, be also provided with temperature detect switch (TDS), for controlling opening or closing of described circulating box delivery port.The temperature of the water storing in circulating box is enhanced, but still does not likely reach the temperature requirement that next stage is used, and therefore, by adding, thermoelectricity is auxiliary to be heated.The operating temperature of described temperature detect switch (TDS) is arranged on 80~85 DEG C, and the temperature of the water storing in circulating box is heated to while reaching requirement, temperature detect switch (TDS) work, and delivery port is opened.After delivery port is opened, 80~85 DEG C of hot water that meet service condition can flow to storage softened water tank.Afterwards, can gather in circulating box from the hot water of the lower temperature of Recovery of the hot water machine, reduce the overall problem of water in circulating box, temperature detect switch (TDS) work, delivery port is closed.Owing to adding the auxiliary heating of thermoelectricity, in the time that water temperature reaches the temperature of instructions for use of 80~85 DEG C again, temperature detect switch (TDS) work, delivery port is opened.So circulation, takes full advantage of the waste heat that cooling pond provides, and the water of suitable temperature is provided to storage softened water tank.
