Description
Technical field: the utility model relates to a kind of spiral plate type heat-exchange apparatus, particularly relates in a kind of spiral plate type heat-exchange apparatus the improvement technology to spiral plate.
Background technology: spiral heat exchanger is since development is come out, apart from the history of modern existing last 100 years.Along with the intensification of people to spiral heat exchanger understanding, continuing to bring out and characteristics such as spiral heat exchanger itself had efficient, anti-obstruction, anti scuffing of new technology, new technology, its application is constantly widened, product is used and has been spreaded all over industries such as oil, chemical industry, metallurgy, light industry, food, papermaking, and has been subjected to people's extensive approval.Existing spiral heat exchanger is divided into removable and two kinds of versions of welded type.Its spiral plate is the critical component of this heat exchanger, and normal circular spacing column or the rhombus spacing column of adopting welds the formation medium channel between adjacent two spiral plates.For the ease of welding, the thickness of slab of spiral plate can not be selected too small, otherwise should not weld.When product rolls, be that to utilize two plates be that welding is curled up at the center with the central partition plate, because that spiral plate contacts with spacing column is insufficient, product can not bear too high pressure, and application is restricted.And when product need bear higher pressure, can only solve, increased material cost, be unfavorable for the saving of the energy by the mode that increases thickness of slab or spacing column density.Simultaneously because welded employing, too many solder joint not only makes troubles to installation, and the welding stress that produces makes product be prone to stress corrosion phenomena in running, has reduced the service life of equipment, has wasted the energy.For this reason, how better to improve the heat-transfer capability of product, maximized energy savings, the service life that strengthens equipment, widen application is the problem of this those skilled in the art's further investigation always.
Summary of the invention: the purpose of this utility model provides the spiral-plate heat exchanger of integral type corrugated plating, mainly be that the existing heat exchanger heat transfer coefficient of solution is low, spacing column and spiral plate weld pads are too many, spiral plate contacts insufficient with spacing column, heat exchanger can not bear too high pressure, is prone to stress corrosion phenomena in the running, reduces service life of equipment, the material cost height, problem such as waste energy.
The utility model purpose is achieved in that it comprises bearing, pressure sleeve, connecting plate, inner sealed board, outer shrouding, carriage, flange, adapter, hanger, also comprise end cap, end cap pad and connecting bolt, it is by being the heat exchange plate that is distributed with the oblique ripple that convex-concave alternately arranges for horizontal segment, both sides in the middle of being provided with, and this plate is that curl up at the center with the horizontal segment, and the corresponding oblique ripple convex-concave of every row supports and form the netted fulcrum at interval and the spiral plate of MEDIA FLOW circulation passage mutually.
Described spiral plate both sides oblique ripple arranges along the plate length direction, and two adjacent row's oblique ripple convex-concaves are opposite, be interspersed, and each convex-concave edge of oblique ripple all is rounding off.
The utility model also has following self particular performances characteristic except the advantage with conventional spiral heat exchanger:
1, be that horizontal segment, both sides are the alternately integral type spiral plate of the heat exchange plate formation of the oblique ripple of arrangement of convex-concave owing to being provided with middle, it substitutes central partition plate and two blocks of spiral plates with a plate, not only simplifies the structure, and has made things convenient for manufacturing, and reduce corrosion, increased intensity.
2, because the setting of the netted fulcrum of convex-concave oblique ripple just can realize turbulent flow under low flow velocity, make film heat transfer coefficient be able to bigger raising, thereby better increase the heat exchange effect.
3, because the setting of the netted fulcrum of convex-concave oblique ripple and steel-sheet adopt, greatly improve the heat-transfer effect and the bearing capacity of product, reduced material cost significantly, saved the energy effectively.
4 because welding stress has not only been eliminated in the cancellation of welding spacing column, has greatly reduced the stress corrosion of equipment, has improved the service life of equipment significantly.
5, because the rounding off at the oblique ripple convex-concave edge of compacting has reduced the medium circulating resistance, saved energy consumption; Can effectively prevent simultaneously the accumulation of medium and the choked flow circulation passage, effectively prolong the cleaning frequency of equipment, make the product clean and maintenance more thoroughly and efficient and convenient.
6, since adjacent two row's oblique ripple convex-concaves opposite, be interspersed, the oblique ripple that each passage is supported mutually can realize again fluid flow to shunting guiding, wash away around the contact, thus the flushing certainly of the equipment of realization, the scale formation that the equipment that effectively prevents is in operation and occurs.Having uniformly transfer heat, the high and low resistance loss of heat transfer coefficient and stronger warm pressure-bearing and the corrosion resistance of holding simultaneously, is that plate type heat exchanger and shell-and-tube heat exchanger are incomparable.
6, also have advantages such as inventive concept novelty, project organization is reasonable, application is extensive, and development prospect is wide, be fit to promote.
