Abstract
The invention discloses a spiral body plate sheet of a spiral plate heat exchanger. The middle part of the plate sheet is a horizontal section, and two sides of the horizontal section are both provided with heat exchange plates provided with concave-convex alternately arranged inclined ripples. According to the invention, a central baffle and two spiral plates are replaced with one plate, product structure is simplified, the spiral body plate sheet is convenient to install and manufacture, welding corrosion is reduced, and mechanical strength is improved. Material cost is lowered, energy consumption is reduced, heat exchange efficiency is improved, the cleaning cycle is increased and the service life is prolonged. Meanwhile, the spiral body plate sheet has the advantages of novel and unique concept, compact and reasonable structural design, self washing capability, wide application scope and broad application prospect and the like, can tolerate higher temperature and pressure, and is suitable for large-scale popularization.
Description
Technical field: the present invention relates to a kind of heat exchanger plate, particularly relate to the improvement technology of a kind of spiral heat exchanger to the spiral plate 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 further 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.And the spiral plate plate is the critical component of spiral heat exchanger, existing spiral plate plate is that to utilize two Zhang Ping's plates be that curl up at the center with the central partition plate, and adopts circular spacing column or rhombus spacing column to weld the formation medium channel between two adjacent flat boards.For the ease of welding, the thickness of slab of spiral plate can not be selected too small, otherwise should not weld.Spiral plate is when rolling, because that plate contacts with spacing column is insufficient, product can only solve by the mode of increase thickness of slab or spacing column density when bearing higher pressure, has increased material cost, is unfavorable for the saving of the energy.Simultaneously because welded employing, too many solder joint not only makes troubles to manufacturing, and the welding stress that produces makes product be prone to stress corrosion phenomena in running, has reduced the service life of equipment.
Summary of the invention: the present invention is for a kind of conveyor screw plate of spiral-plate heat exchanger is provided.Purpose is by the improvement to the spiral plate plate in the existing spiral heat exchanger, better improve the heat transfer property of product and under the situation of certain sheet, improve bearing capacity, the maximized energy savings that reduces cost, reduce the welding link and improve performance, strengthen service life of equipment, widen application, satisfy the demand of more users.
Conveyor screw plate of the present invention is to be horizontal segment by the centre, is in the both sides of horizontal segment to be provided with the heat exchanger plates that oblique ripple that convex-concave alternately arranges constitutes.
Its both sides oblique ripple of conveyor screw plate of the present invention arranges along the plate length direction, and adjacent two row's oblique ripple convex-concaves are opposite, be interspersed, and each convex-concave edge all is rounding off.
Conveyor screw plate of the present invention is being that curl up at the center with the horizontal segment, and the convex-concave of the oblique ripple that every row is corresponding supports mutually, forms netted fulcrum and two media circulation passage at interval.
The present invention compared with prior art has the following advantages and good effect:
1, be that horizontal segment, both sides are the alternately conveyor screw plate of the oblique ripple formation of arrangement of convex-concave owing to being provided with middle, substitute central partition plate and two blocks of spiral plates with a plate, not only simplified product structure, made things convenient for the manufacturing, and reduced corrosion due to welding, increased mechanical strength.
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, not only improve the heat-transfer effect and the bearing capacity of product, and reduced material cost significantly, saved the energy effectively.
4, because welding stress has not only been eliminated in the cancellation of welding spacing column, greatly reduce the stress corrosion of equipment, improved the service life of spiral plate and even equipment significantly.
5, because the equal rounding off in oblique ripple convex-concave edge of compacting can effectively prevent the accumulation of medium and the choked flow circulation passage, effectively prolonged the cleaning frequency of equipment.
6, since adjacent two row's oblique ripple convex-concaves opposite, be interspersed, make oblique ripple that each passage supports mutually realize fluid flow to the 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 prior art is incomparable.
7, moreover, this invention also has inventive concept novel uniqueness, structural design compact and reasonable, is widely used advantage such as have a extensive future, be fit to widely popularize.

The specific embodiment: the conveyor screw plate of spiral-plate heat exchanger of the present invention is a kind of new type heat exchanger plate that is used for spiral heat exchanger.It is to be horizontal segment 1 by the centre, is in the both sides of horizontal segment 1 to be provided with the heat exchanger plates that oblique ripple 2,3 that convex-concave alternately arranges constitutes.Its both sides oblique ripple 2,3 of described conveyor screw plate of the present invention arranges along the plate length direction, and adjacent two row's oblique ripples, 2,3 convex-concaves are opposite, be interspersed, and each convex-concave edge all is rounding off.In addition, the present invention also can be arranged to version equal or that do not wait with the length or the convex-concave degree of depth of oblique ripple 2,3 according to the heat exchange demand.
During installation, spiral plate plate of the present invention is being that curl up in the conveyor screw of formation at the center with horizontal segment 1, and the oblique ripple 2 and 2 of every row's correspondence, 3 and 3 convex-concave support mutually, form netted fulcrum and two media circulation passage at interval.Realize the purpose of heat exchange with this.
