Description
(1) technical field
The utility model relates to a kind of heat exchanger, specifically a kind of efficient plated film vortex heat exchanger.
(2) background technology
At present, China's central heating generally launches in each big city, because the heat exchanger structure form is different, the heat exchange effect is very different.Though advantages such as heat exchanger is firm with compact conformation, and applicability is strong are widely used, the low development that is restricting heat exchanger of heat transfer property is difficult to reach energy-conservation and relevant requirements environmental protection.Mainly show following three aspects:
1, to exist heat exchange efficiency low for traditional heat exchangers, and running resistance is big, the problem that the life-span is short
The coefficient of heat transfer of traditional heat exchangers is all lower, and direct result is that heat exchange area is big, and promptly heat exchanger volume is bigger.This heat exchanger condensing water temperature is a saturation temperature, and the waste of double evaporation-cooling is bigger, and the way of having to take to install steam trap additional is carried out block steam and drain water, has directly caused the waste of the energy.Fa Zhan forced heat-exchanging device reached the effect of forced heat-exchanging by changing heat exchanger tube form or the various reinforcing elements of interpolation afterwards.This heat exchanger running resistance is big by 20%, and the interpolation assembly life-span generally is no more than 8 years, causes the heat exchanger life-span low, and the repeated construction waste is huge.Various cantilever floating coiler heat exhanger vibrations are excessive, and root is torn easily, and the life-span can not guarantee at all.
When 2, heat exchanger was worked, noise was excessive, contaminated environment
Traditional temperature-controlled process is the size of control quantity of steam, and when required steam flow was smaller, the aperture of control valve was very little, and is at this moment especially little in the pressure drop of control valve, and this pressure drop makes control valve produce huge noise.Through test, this kind noise can reach more than 110 decibels when maximum.
3, condensate temperature is too high, and energy waste is huge
The control of common steam water heat exchanger is the size of controlling the heat exchange amount by the size of control steam flow, in the traditional design of heat exchanger, steam trap is equipped with at the mouth of a river of condensing of heat exchanger, and purpose is that the condensate water in the heat transfer process is in time drained, and steam is stayed continue heat exchange in the heat exchanger.Even if like this, when condensate water when steam trap outlet is flowed out, this part saturation water evaporates a large amount of water vapours owing to pressure reduces suddenly, when the water temperature of this part saturation water is reduced to below 100 ℃, existing nearly water over half has evaporated, reason is that traditional heat exchanger can not be cooled to steam below 100 ℃ when heat exchange, steam with 0.4Mpa is example, the * 1000=51000kcal/ht of heat loss=(151-100), the heat of steam per ton is 600,000 kilocalories, heat loss rate=51000/600000=0.085=8.5%.This shows that steam pressure is high more, heat loss is big more.
In sum, the raising of heat exchanger performance should improve the coefficient of heat transfer from energy-saving and cost-reducing, and aspects such as saving cost address.
