Description
Technical field
The present invention relates to the low temperature exhaust heat transportation of a kind of iron and steel enterprise and utilize method, especially utilize iron and steel enterprise's low temperature exhaust heat to supply with the low-grade method in city, belong to the heat recovery technology field with the hot user of ability.
Technical background
Iron and steel enterprise is energy resource consumption and CO
2The discharging rich and influential family, its energy consumption and CO
2Discharging accounts for industrial total energy consumption and CO respectively
2About 16% of discharging.Produce a large amount of low temperature exhaust heats in iron and steel enterprise's production process, comprise hot water, low-grade flue gas and steam etc., these amount of heat are big, grade is low, and recycling good these low temperature exhaust heats is to reduce the energy consumption of iron and steel enterprises and CO
2The effective way of discharging.
UTILIZATION OF VESIDUAL HEAT IN mainly is to reclaim its heat energy through the heat exchange means; Can it be transported to the place that needs waste heat through pipeline for the liquid waste heat and carry out the heat exchange recovery; Gas waste-heat for difficult conveyings such as flue gases can not carry out waste heat recovery through the mode that pipeline is carried; Must use a kind of novel waste heat recovery mode, with being transported to the user who needs low temperature exhaust heat after its waste heat recovery.Therefore, the system that carries out UTILIZATION OF VESIDUAL HEAT IN through transport pathway becomes the focus of concern, finds that through consulting related data the domestic waste heat that utilizes does not almost have the research that iron and steel enterprise's waste heat reclaims.
The iron and steel enterprise low temperature exhaust heat is recycled and also is in the research and development stage at present, and subject matter is that the rate of recovery is low, can only recovery section low temperature exhaust heat, for example winter heating and preheating etc.; Low and the key technology of system effectiveness does not solve, for example the organic working medium low-temperature cogeneration.Solve the rate of recovery and the inefficient problem of recovery system, iron and steel enterprise's low temperature exhaust heat is significant for reclaiming.
Along with the development of phase-changing energy storage material technology, energy storage technologies more and more obtains people's attention.And these memory technologies are mainly used in to the storage of the heat of solar energy or to the peak load shifting of commercial power, and these methods can only be used for fixing the place with the heat of storage, lack flexibility, for carry out the domestic few people's research of UTILIZATION OF VESIDUAL HEAT IN through transport pathway.Therefore, the iron and steel enterprise's low temperature exhaust heat through heat exchange, storage and transportation utilizes method, both can the heat that reclaim be transported to the different hot user who needs heat, solves because the fixing low problem of the rate of recovery that is caused of hot user; Can the low temperature exhaust heat that reclaim be used for heat supply according to the principle of energy cascade utilization again simultaneously and require lower hot user, improve the efficient of recovery system.
Summary of the invention
The objective of the invention is rational recycling through iron and steel enterprise's low temperature exhaust heat; Improve the low temperature exhaust heat rate of recovery and recovery system efficient; Exploitation iron and steel enterprise low temperature exhaust heat transportation technology; Thereby the method for a kind of iron and steel enterprise low temperature exhaust heat transportation is provided, can be widely used in the recovery of iron and steel enterprise's low temperature exhaust heat.

A: in iron and steel enterprise flushing cinder pond heat exchanger (as shown in Figure 1) is installed, is extracted the industrial wastewater in flushing cinder pond, the cycle fluid import 8 entering heat exchangers by heat exchanger 1 conduct heat to phase-change material 3, discharge from cycle fluid outlet 5;
B: when extracting industrial wastewater, with the heat conductive oil inlet 6 feeding heat exchangers of conduction oil from heat exchanger 2, heat conducts to conduction oil from phase-change material 3, discharges heat exchangers 2 from conduction oil outlet 7 at last;
C: the heat conductive oil inlet 6 with the conduction oil feeding phase-change material holding vessel (as shown in Figure 2) of discharging among the step B, heat is conducted to phase-change material, to discharge from conduction oil outlet 7 then, recirculation gets into heat exchanger; When amount of stored heat reaches phase-change material holding vessel storage capacity, finish heat exchange, arrive the heat release system through vehicles drive;
D: the phase-change material holding vessel that step C is obtained is with vehicle transport to heat release system (urban population centralized residence area); Conduction oil is fed the heat exchanger of heat release system end; Method according to steps A and B heats cycle fluid equally; Then cycle fluid is fed hot user, the cycle fluid that will from hot user, discharge at last continues to feed the cycle fluid inlet 8 of heat release system end, forms closed circuit.
The temperature of said industrial wastewater is 80～100 ℃.
The phase-change material of said heat exchanger and phase transformation holding vessel adopts paraffin wax, because the waste heat that reclaims belongs to low temperature exhaust heat.
Said conduction oil can be synthesis type conduction oil and mineral type conduction oil.
Cycle fluid among the said step D is water, conduction oil, organic working medium etc.
Said heat exchanger and phase-change material holding vessel are existing equipment, in order to reduce the loss of heat in heat exchange and the transportation, need all wrap up insulation material to heat exchanger and phase-change material storage tank body 9 outsides and be incubated.
The phase-change material holding vessel of the intact heat of the release among the said step D adopts haulage vehicle to transport back the heat reservoir store heat, obtains circulation and uninterrupted in order to make energy, can adopt a plurality of phase-change material holding vessels and many haulage vehicles.
At same mounting heat exchanger of hot user side and circulating pump; The heat of phase change material stores is passed to heat-conducting medium-conduction oil; Conduction oil gets into heat exchanger through circulating pump, through heat exchange heat is discharged to hot user, and conduction oil is got back to the phase-change material holding vessel and circulated next time.After the heat of phase-change material holding vessel storage has discharged, stop circulating pump, finish heat exchange, go back to iron and steel enterprise flushing cinder pond through vehicles drive.
Advantage that the present invention and prior art relatively have and good effect:
1, through waste heat transportation system, the low temperature exhaust heat of iron and steel enterprise can be transported to the hot user of different location, has improved the rate of recovery 10～15% of iron and steel enterprise's low temperature exhaust heat, has enlarged the scope of utilizing of low temperature exhaust heat;
2, overcome with low-quality can be converted into high-quality can process in recovery system efficient low, really realized the cascade utilization of the energy, improved the efficient of recovery system;
3, the method for iron and steel enterprise's low temperature exhaust heat transportation has realized that with iron and steel enterprise's low temperature exhaust heat be thermal source, uses the waste heat transportation system of heat unit for hot user, has reduced hot user's fuel consumption and CO
2Deng discharge capacity;
4, with existing UTILIZATION OF VESIDUAL HEAT IN compared with techniques, can reclaim low temperature exhaust heat fully and be used, overcome traditional waste heat recovery mode, all the shortcoming of recovery waste heat; Because waste heat transportation system carries the waste heat mode flexible, reduced simultaneously because the investment of transporting low temperature waste heat tubing.
