Description
Technical field
The invention belongs to heat exchange equipment fields, and in particular to a kind of double pipe heat exchanger with special-shaped inner tube.
Background technique
Heat exchanger is the section that heat transfer between material is realized between a kind of fluid at two or more different temperatures
Energy equipment, is that heat is made to pass to the lower fluid of temperature by the higher fluid of temperature, fluid temperature (F.T.) is made to reach flow specification
Index to meet the needs of process conditions, while being also one of the capital equipment for improving energy utilization rate.Heat exchanger industry is related to
HVAC, pressure vessel, sewerage disposing equipment, chemical industry, nearly 30 multi industries such as petroleum mutually form industry chain (supply chain).
Heat exchanger main body is heated by the water that high-temperature flue gas is exchanged in thermal sleeve, realizes the transmitting of temperature, but right
During water heats, the casing of usual heat exchanger, the set-up mode being also arranged using inner and outer tubes, but the shape of conventional inner tube
Shape is round or oval, and inner tube and the contact area of outer liquid in pipe are few, and heat exchange efficiency is lower, and are easy in inner tube attached
Bubble, inner tubal wall is caused to corrode.
Summary of the invention
It is an object of the invention to: it is round or oval for the shape of conventional inner tube set forth above, inner tube and outer
The contact area of liquid in pipe is few, and heat exchange efficiency is lower, and bubble easy to attach in inner tube, causes corrosion to inner tubal wall
Problem, the present invention provide a kind of double pipe heat exchanger with special-shaped inner tube.
The technical solution adopted by the invention is as follows:
A kind of double pipe heat exchanger with special-shaped inner tube, including heat exchanger main body, heat exchanger main body are equipped with Heat exchange jacekt
Pipe, the heat exchange sleeve include inner tube and the outer tube that is set in outside inner tube, and the tube wall of inner tube is recessed inwardly and is rendered as inner tube
Have there are four the cross of tongue, the tube wall of inner tube is arcwall face, is uniformly provided on the arc inner wall of the tongue several anti-
Swirl plate, centered on the arc core of curved tongue, annular array is distributed on tongue inner wall anti-swirl plate, the anti-swirl plate
Surface is equipped with soft hairbrush.
The casing of usual heat exchanger, the set-up mode being also arranged using inner and outer tubes, but the shape of conventional inner tube is circle
Shape or ellipse, the shape of this inner tube be rendered as by the tube wall invagination of inner tube it is cross so that inner tube and outer liquid in pipe
Contact area is bigger, therefore heat exchange efficiency is higher, and since inner tube is invaginated, while also will appear tongue, and liquid in inner tube
When flowing, it is easy to form vortex at tongue or remains bubble at tongue, vortex can reduce liquid in inner tube
Flow efficiency, bubble have included oxygen, and attachment overlong time can make inner pipe wall by oxidation corrosion, reduce the service life；And
The anti-swirl plate being arranged can avoid the generation of vortex and smash the bubble in water, so that the flow efficiency of liquid is more in inner tube
Height, and oxidation of the tube wall by bubble is avoided, while the soft hairbrush on anti-swirl plate, it on the one hand can adsorb the liquid of surrounding
Body avoids the attachment of bubble, and on the other hand, soft hairbrush can smash bubble, make with the random swing of the flowing of liquid
Bubble in liquid can not adhere to also can not long-term existence.
Further, it is welded and fixed between said inner tube and outer tube by inner tube welding rod.
Further, the heat exchanger main body further includes that heat exchange sleeve both ends are arranged in for clamping the installation of heat exchange sleeve
Baffle, the number of heat exchange sleeve are 3-5, are connected between adjacent heat exchange casing by bend pipe, and the heat exchange sleeve, which is equipped with, inhales
Backing.
Further, the installation baffle is equipped with the life water inlet pipe being separately connected with two ports of inner tube and lives out
Water pipe.Being discharged into and being discharged for domestic water of life water inlet pipe and life outlet pipe.
Further, the heating water inlet pipe being separately connected with two ports of outer tube and heating are additionally provided on the installation baffle
Outlet pipe.Being discharged into and being discharged for heating water of heating water inlet pipe and heating outlet pipe.
Further, the material of the soft hairbrush is nylon yarn.Nylon is that toughness horn shape is translucent or creamy white crystals
Property resin, the nylon molecular weight as engineering plastics are generally 1.5-3 ten thousand.Nylon has very high mechanical strength, and softening point is high,
Heat-resisting, coefficient of friction is low, wear-resistant, self-lubrication, shock absorption and sound-deadening properties, oil resistant, weak acid resistant, alkaline-resisting and common solvent, electricity
Good insulating has self-extinguishment, nontoxic, odorless, good weatherability, and dyeability is poor.Water imbibition is big, influences dimensional stability and electrical property
Can, fiber reinforcement can reduce resin water absorption rate, can work under high temperature, high humidity.Therefore this soft preferred fiber Buddhist nun of hairbrush
Nylon yarn.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. the anti-swirl plate that the present invention is arranged can avoid the generation of vortex and smash the bubble in water, so that liquid in inner tube
The flow efficiency of body is higher, and avoids oxidation of the tube wall by bubble, while the soft hairbrush on anti-swirl plate, on the one hand may be used
To adsorb the liquid of surrounding, the attachment of bubble is avoided；
2. soft hairbrush of the invention can smash bubble, so that in liquid with the random swing of the flowing of liquid
Bubble can not adhere to also can not long-term existence；
3. two kinds of functions of heating and supplying hot water, common single tube can be achieved at the same time using casing in the present invention compared with common single tube
Can only realize single heating function, realized for complete machine it is difunctional also need to increase a plate change and Electrocontrolled tee valve, cost
It is higher therefore purchase cost can be reduced for complete system plant using casing.
