At present, Summarization on heat transfer enhancement in heat exchangers generally adopts the passive facilitation measure that changes heat transfer structure and surface appearance thereof, when realizing augmentation of heat transfer, flow resistance is significantly increased, and the speed of flow resistance increase is far longer than the speed of conducting heat and increasing in many cases, correspondingly increased the power consumption of system, this is unfavorable for high efficiente callback waste heat and energy-saving and cost-reducing.Therefore, the structural development of heat exchanger and combination property are improved and are very limited.
The utility model content
The purpose of this utility model is to provide a kind of multi-stage condensing synthesis energy saving high-performance heat exchanger, be intended to solve present Summarization on heat transfer enhancement in heat exchangers and generally adopt the passive facilitation measure that changes heat transfer structure and surface appearance thereof, when realizing augmentation of heat transfer, flow resistance is significantly increased, and the speed of flow resistance increase is far longer than the speed of conducting heat and increasing in many cases, correspondingly increased the power consumption of system, this is unfavorable for high efficiente callback waste heat and energy-saving and cost-reducing problem.
The utility model is achieved in that a kind of multi-stage condensing synthesis energy saving high-performance heat exchanger, and described heat exchanger comprises the first-class heat exchanger that connects successively, secondary heat exchanger, three grades of heat exchangers.
Further, the freezing machine of the lithium bromide of described heat exchanger is connected with described first-class heat exchanger, secondary heat exchanger, three grades of heat exchangers respectively.
Further, the lithium bromide refrigerator of described heat exchanger links to each other with first-class heat exchanger, secondary heat exchanger, three grades of heat exchangers respectively by water inlet pipe.
The multi-stage condensing synthesis energy saving high-performance heat exchanger that the utility model provides, although set up the cooling unit, the power of its refrigeration is to utilize original high-temperature gas, having saved increases firing equipment again.The cold water of refrigeration unit injects respectively a heat exchanger, two heat exchangers, three grades of heat exchangers, causes the original high-power normal-temperature water water supplying pump cooling of using, and does not also need the water of large flow to inject, and the one, saved water, the 2nd, reduce horsepower and saved electricity consumption.Can realize the recycling of the energy, a large amount of energy savings.Compact conformation, volume is little, saves equipment and materials, and three cooling tube bundles can conveniently be extracted out, and maintenance is convenient.And the fin of three cooling tube bundles and air-flow direction are in the same way, reduced air drag, reduced pressure drop.Transportation is installed, and keeps in repair all very convenient.
Description of drawings
Fig. 1 is the structure flow chart of the multi-stage condensing synthesis energy saving high-performance heat exchanger that provides of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the structure of the multi-stage condensing synthesis energy saving high-performance heat exchanger that the utility model provides.For convenience of explanation, only show the part relevant with the utility model.Concrete structure is as follows:
First-class heat exchanger 1,2, three grades of heat exchangers 3 of secondary heat exchanger, the freezing machine 4 of lithium bromide, water pump 5.
First-class heat exchanger 1,2, three grades of heat exchangers 3 of secondary heat exchanger connect successively, and the freezing machine 4 of lithium bromide is connected with three grades of heat exchangers 3 with first-class heat exchanger 1 respectively, and water pump 5 links to each other with secondary heat exchanger 2.
Be that 128m3, temperature are 1750 ℃ high temperature air fluid with the per minute flow, reducing to the per minute flow is that 82m3, temperature are 150 ℃ pure and fresh dry air.
According to above-mentioned designing requirement, the high temperature compressed gas that utilizes air compressor to discharge extracts the thermal source in the high-temperature gas, as the thermal source of the freezing machine 4 of lithium bromide.Capacity of example is 200-500m/min, and delivery temperature is 175 ℃, establishes first-class heat exchanger 1, and the main purpose of first-class heat exchanger 1 will for the freezing machine 4 of lithium bromide provides 80-85 ℃ of heat source water, replace the lithium bromide Steam Heating exactly.At this time the delivery temperature through overcooled first-class heat exchanger 1 drops to 120 ℃, establishes secondary heat exchanger 2 again, again 120 ℃ air is dropped to≤40 ℃, use be the normal temperature cooling water.There is water circulating pump 5 to supply with.If the compressed air that three grades of heat exchangers 3 will≤40 ℃ will dehumidify in this one-level, and is further dry compressed-air actuated moisture, make it reach 15 ℃, the chilled water of use is supplied with from the freezing machine 4 of lithium bromide, the water at low temperature that freezing machine 4 supplies of lithium bromide are 10 ℃.Finally reached energy-conservation purpose.
This multi-stage condensing synthesis energy saving high-performance heat exchanger, although set up the cooling unit, the power of its refrigeration is to utilize original high-temperature gas, having saved increases firing equipment again.The cold water of the freezing machine 4 of lithium bromide injects respectively 1,2,3 three grade of heat exchanger, causes the original high-power normal temperature water pump 5 of using for water cooling, does not also need the water of large flow to inject, and the one, saved water, the 2nd, reduce horsepower and saved electricity consumption.Can realize the recycling of the energy, a large amount of energy savings.Compact conformation, volume is little, saves equipment and materials, and three cooling tube bundles can conveniently be extracted out, and maintenance is convenient.And the fin of three cooling tube bundles and air-flow direction are in the same way, reduced air drag, reduced pressure drop.Transportation is installed, and keeps in repair all very convenient.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
