Background technology
Waste heat is in a certain thermal process process, is not utilized in using energy source equipment, unnecessary, the discarded energy.Mainly comprise seven kinds of high-temp waste gas waste heat, cooling medium waste heat, waste vapour waste water residual heat, high-temperature product and afterheat of slags, chemical reaction waste heat, combustible exhaust gas waste liquid and waste material waste heat and high-pressure fluid waste heats etc.The waste heat total resources of every profession and trade account for 17%～67% of its fuel consumption total amount, the wherein recyclable utilization of 60% residual heat resources.Along with energy-conservation active demand and enterprise self reduce cost and promote the needs of product competitiveness, heat recovery comes into one's own day by day.At present, in the emphasis power consumption fields such as chemical industry, iron and steel, pottery, building materials, the medium and high temperature heat recovery technology more than 100 ℃ is comparative maturity, but the recycling of low temperature exhaust heat below 100 ℃ does not also cause enough attention.As iron and steel enterprise, high-temperature residual heat more than 50% and 40% above middle temperature waste heat are recycled, but for the low temperature exhaust heat below 100 ℃, recovery utilization rate is less than 1%.Low temperature exhaust heat also often runs in other industry and civil area, mainly is the cooling water of technique waste water or equipment.In addition, industries such as papermaking, food also have a large amount of low temperature exhaust heats to recycle.
Low temperature exhaust heat below 100 ℃ is reclaimed, and its key problem in technology is exactly a high-performance heat exchanger.Because heat source temperature is low, require heat exchanger hanging down heat exchange under the temperature difference, and heat transfer temperature difference is low more, the waste heat recovery effect is good more, and energy-saving potential is also big more.At present, the domestic heat recovery heat exchanger that is extensive use of traditional bow type membrane support plain tube, there is following shortcoming in this heat exchanger:
1. fluid round baffling between deflection plate washes away tube bank between pipe, and the fluid body resistance that baffling causes in this process is big, pressure drop is high, causes that easily bundle vibration destroys;
2. there is flow dead in bow type dividing plate, the easy fouling of medium, thus influence the performance and the service life of heat exchanger;
3. adopt plain tube to carry out heat exchange, heat transfer temperature difference is bigger, realize low temperature difference heat exchange, then needs very big heat exchange area, therefore can cause the increase of cost.
Adopt the heat exchanger of spiral shell side structure, have fluid and flow evenly, do not have the dead band, pressure drop is low and be difficult for causing the advantage of tube bundle vibration; And adopt helical baffles can overcome the inherent defect of bow type baffle heat exchanger as the heat exchanger of supporting construction between pipe; Helical baffles and two-sided strengthened pipe are arranged in pairs or groups, can further improve the heat transfer property of heat exchanger, thereby realize low temperature difference heat transfer.Therefore, the two-sided strengthened pipe high-performance heat exchanger of helical baffles is particularly suitable for the recycling of low temperature exhaust heat.
