Abstract
The utility model discloses a waste heat recovery system, which is a comprehensive utilization system for industrial energy, and comprises a technical cooling water tank, a heat pump and heat-exchange equipment; the technical cooling water tank is connected with an evaporator intake of the heat pump through a pipeline; an evaporator outlet is connected with the heat-exchange equipment through the pipeline; a condenser of the heat pump is connected with a heat consumption system. The waste heat recovery system is adopted for enhancing the grade of the prior nonrecoverable low grade technical cooling water through the heat pump system, and then the high-grade technical cooler water is used in heat consumption system to implement heating and hot water supply, thereby the utility model not only can recycle the energy, but also can reduce the load of the heat-exchange equipment, so the pollution from coal, oil or gas-fired boiler heating or hot water supply can be avoided, and the energy resource consumption can be reduced.
Description
Technical field
The utility model relates to a kind of energy network coupling system, is a kind of heat integration system that adopts heat pump.
Background technology
Industrialization is the sign that human history enters civilization, and industrial civilization and human life are closely bound up.Along with the sustainable growth of China's economic in recent years, industrialized paces are also constantly accelerated, and a large amount of newly-built factories put into production just continuously, and the industry in many batches of the preparing is also ready to appear.For the industrialization revolution that China took place, it is that advantage is leading with human resources and land resource cheaply mainly, and these industry mostly are the enterprises of high energy consumption, high pollution.In a lot of big industry (as electronics industry, auto industry, pharmaceuticals industry etc.) production process in the past, often produce a large amount of technology cooling waters, these technology cooling waters must be reduced to below certain temperature and can reuse in process of production, because the temperature of these technology cooling waters is not enough to reach the temperature that we carry out winter heating, therefore at present common way is by certain heat transmission equipment, and its heat is discharged in the middle of the environment.So not only caused the huge waste of the valuable energy (water resource, coal, oil, liquefaction vapour etc.), and also can cause thermal pollution and exhaust emission environment.
The utility model content
The energy waste and the pollution problem that exist at the mode of cooling of existing industrial colling, the purpose of this utility model is to provide a kind of industrial energy utilization system, adopt this system the heat of the technology cooling water that produces in the technical process can be reclaimed comprehensive utilization, reach energy-conservation and reduce the purpose of environmental pollution.
So-called heat pump techniques is exactly by the circulation of thermodynamics Kano, by certain electric energy, low-grade energy is transferred to high-grade energy.The utility model utilizes this technology that low-grade heat energy of the low technology cooling water that can not directly use of potential temperature is fully utilized.The utility model adopts following technical scheme: the industrial energy utilization system comprises technology cooling pond, heat pump and heat transmission equipment, the technology cooling pond is connected with the evaporator inlet of heat pump by pipeline, evaporator outlet is connected with heat transmission equipment by pipeline, the condenser of heat pump be connected with hot system.
Described heat pump can be compression heat pump.
The technology cooling water of the low potential temperature that produces in the technical process enters the technology cooling pond, enter the evaporimeter of heat pump then from the technology cooling pond, discharge to the refrigerant in the heat pump by the heat of evaporimeter the technology cooling water, the technology cooling water is lowered the temperature simultaneously, and the technology cooling water after the cooling returns reuse in the technical process again after heat transmission equipment is cooled to the temperature of technological requirement.Heat pump cycles through heat pump by the thermodynamics Kano condenser is used for heating or heat supply water with heat transferred as the intrasystem water of the heat-obtaining of the cooling medium of heat pump under the condition that is higher than evaporating temperature (reaching heating temperature), the temperature of the intrasystem water of heat-obtaining is raise.The heat that the technology cooling water had has been used for heating or heat supply etc. after being upgrade by heat pump by certain electric energy, produce more than 4 times in the energy of the electric energy that heat pump consumed, heating or generation hot water between supply car, the technology cooling water temperature has obtained reduction simultaneously, reduced to environment and entered energy, reduce the load of cooling device simultaneously, reduced equipment investment; In addition,, reduced the direct exhaust emission that produces with fire coal, oil, liquefied gas that Boiler heating caused, reduced the consumption of valuable fire coal, oil, gas because energy is recovered utilization.Compare with the operating cost of gas fired-boiler, the operating cost that uses heat-pump apparatus is than reducing more than 50%; Compare with the operating cost of oil burning boiler, the operating cost that uses heat-pump apparatus is than reducing more than 60%.
Description of drawings
Fig. 1 is an industrial energy utilization system schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing industrial energy utilization system of the present utility model is described further.
As shown in Figure 1, the technology cooling water that produces in the commercial plant is collected in technology cooling water pond 1, the evaporimeter (omitting among the figure) that is conveyed in the heat pump 3 by pipeline 2 discharges heat then, reduces technology cooling water after the temperature and enters heat transmission equipment 6 through pipeline 5 again and further be cooled and return technical process after the temperature that is cooled to the needed regulation of production technology and recycle.The condenser of heat pump 3 (omitting among the figure) inserts with in the hot system by heating pipeline 7, heat pump 3 makes the grade of low-grade heat of evaporimeter absorption promote back release under higher temperature by consumed power and uses to make it intensification with the water in the hot system, replace combustion gas, oil or coal-burning boiler to be used for heating or generation hot water.The energy of the technology cooling water that reclaims by heat pump is more than 4 times of electric energy that heat pump consumes, and the more gas fired-boiler heating of the operating cost of system reduces more than 50%, compares with the operating cost of oil burning boiler and reduces more than 60%.
