Description
Technical field
The utility model is related to field of heat exchange, and in particular to a kind of superconduction fluidised form heat exchanger.
Background technology
The average thermal efficiency of industry coal-boiler only has 67%, 25% heat energy by fume emission to air in the middle of, row
Cigarette temperature is up to more than 200 DEG C, both pollutes environment, and the fume afterheat resource of preciousness is wasted again.Therefore many large-sized boilers
The shell-tube type economizer of cast iron or stainless steel is mounted on, is fed water for Mist heat recovering preboiler.
But because the sulfur content of coal is higher, oxysulfide would generally be produced during burning, i.e. shape after being combined with vapor
Into sulfuric acid vapor.When the set point (referred to as acid dew point) of the metal pipe-wall temperature less than sulfuric acid vapor of economizer, will be in its table
Face forms liquid sulfuric acid (referred to as condensing).
For a long time, the corrosion that traditional shell-tube type economizer is caused due to condensation, or even perforated phenomenon occurs often, sternly
Ghost image rings the operation safety of boiler, so current boiler is all to alleviate condensation and corrosion phenomenon by improving exhaust gas temperature
Produce, flue-gas temperature remains high.In addition the bulky of this kind of economizer, flue gas resistance are big, easy dust stratification, stifled ash, heat exchange
Efficiency is reduced year by year, and service life is short, often wants deashing, therefore medium small boiler to be rarely employed, when large-sized boiler uses one section
Between after, it is basic without high-temperature flue gas of leaving take away heat, waste the energy because fouling is serious.Under boiler smoke temperature is every
15~18 DEG C of drop can improve boiler efficiency 1%, therefore reduction boiler smoke temperature has turned into an important way of boiler energy-saving
Footpath, while must solve the problem of heat exchanger tube low-temperature corrosion again, then heat pipe type of coal saver is just applied and given birth to.
Radial heat pipe being used existing heat pipe type of coal saver, its structure type is more：Many radial heat pipe elements lie in a horizontal plane in
In the flue be made up of economizer housing, each branch heat-pipe elements structure in same level (or vertical) face is in a row；In heat pipe
Housing is stretched out at pipe two ends, adjacent row or is separated by corresponding heat pipe inner tube in a row and is concatenated by seamless elbow and be integrated；First, last two
Heat exhausting pipe has one end not concatenated with elbow, but is connected in parallel by header is integrated respectively.The vertical radial heat pipe of flue gas is from cigarette
Road flows through, and water flows into header side, and uniformly flows into first row (or the end row) heat pipe being connected with the header, then flows successively through each
Heat exhausting pipe, finally flows out from opposite side.Flue gas and heat pipe outer tube and fin contacts, it is completely separated with heat pipe inner tube；Heat pipe inner tube
Weld seam between two ends and seamless elbow is also completely outside flue.
Said structure has following drawback：1. header specification is larger, generally Φ 800, for manufacture installation brings difficulty；
2. after fume side leakage, whole pipe must all be changed, and cause maintenance cost to increase, and maintenance difficulty is big.For the design of above-mentioned drawback
A kind of superconduction fluidised form heat exchanger, and in the market without such device.
The content of the invention

Water side and fume side tube construction, improve heat exchange efficiency, reduce production and install and operating cost.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of superconduction fluidised form heat exchanger, including
Framework, the framework is divided into upper and lower two-layer, and the upper strata is set to water body side frame, and the lower floor is set to flue gas body side frame, the water
It is provided between body side frame and flue gas body side frame into water header, is provided with protective cover around the water inlet header and is connected with framework；
Several columns light pipe is provided with perpendicular to water inlet header in the framework, heat-exchange working medium, the water are provided with the light pipe
Outer tube is cased with outside light pipe in body side frame, is had water in the space between the light pipe and outer tube and is connected with the water inlet header,
The water body side frame top is provided with water outlet header, and the water outlet header and the space between light pipe and outer tube connect.
Used as preferred technical scheme, the light pipe in the flue gas body side frame is provided with fin.
Used as preferred technical scheme, light pipe and fin in the flue gas body side frame have enamel.
Used as preferred technical scheme, the light pipe uses the pipe of Φ 42*3, the outer tube to use the pipe of Φ 89*6.
Used as preferred technical scheme, the framework is provided with the hanger for conveniently removing and installing.
The utility model is beneficial in that：
1. traditional water inlet header is changed to common header, be reduced in size, reduce production and installation difficulty.
2. after the light pipe leakage of fume side, the light pipe of fume side need to be only changed, reduce operation and maintenance cost.
3. heat exchange efficiency is improved after the heat exchanger internal structure changes, and can realize that module is given birth to according to heat exchange efficiency
Produce, reduce cost.
4. the light pipe of fume side and fin enamel are processed, and can also improve its service life.
