Description
Technical Field
The utility model relates to a heat exchanger slab, specific wide passageway welding plate heat exchanger slab of flue gas waste heat recovery that says so.
Background
At present, the welded plate heat exchanger structure for recovering the waste heat of the flue gas in China is usually formed by adding distance columns or distance bars between two parallel plates so as to achieve the purpose of increasing the heat transfer coefficient by turbulent flow of a medium, and has the defect that the corrosion risk is increased due to welding spots added between the distance columns or the distance bars between the parallel plates and the heat exchange plates.
Disclosure of Invention
The utility model aims to provide a wide channel welding plate type heat exchanger plate for flue gas waste heat recovery, which has simple structure and two structures of V-shaped shallow groove external corrugation and semi-circular groove internal corrugation, and can lead fluid to form larger turbulence at low flow velocity and obtain higher heat transfer coefficient; when the plate pairs are combined in parallel, the supporting points on the plates are mutually supported, so that the purpose that the heat exchanger bears high pressure can be achieved.
The utility model aims at realizing like this, a wide passageway welding plate heat exchanger slab of flue gas waste heat recovery, this heat exchanger slab include a slab main part, have horizontal alternative interval arrangement's half slot internal corrugation along horizontal processing in the slab main part, are provided with the outer ripple of V type shallow slot that is the splayed and arranges between two adjacent half slot internal corrugations, the V type recess on the outer ripple section of V type shallow slot is shallower than the half slot on the ripple section of half slot.
Two first inner supporting points are arranged at two vertex angles on one side of the plate body, and a second inner supporting point is arranged at the center of the other side of the plate body.
First outer supporting points are respectively arranged between the adjacent two semi-circular groove inner corrugations, and a second outer supporting point is arranged at the outer end of each V-shaped shallow groove outer corrugation.
The utility model has the advantages of it is following and positive effect:
1. the utility model discloses the heat exchanger slab adopts one shot forming structure, and the centre does not have any solder joint, and two kinds of structures of V type shallow slot outer ripple and half slot inner ripple have been suppressed on heat transfer slab surface, make the slab to when carrying out many to parallel combination, the strong pressure purpose is born to the strong pressure each other to the strong point of support on the slab, can reach the heat exchanger.
2. The utility model discloses the outer ripple of V type shallow slot and the interior ripple of half slot of heat transfer plate sheet design can make the fluid form great torrent under the low velocity of flow, gains higher coefficient of heat transfer.
3. The utility model discloses because the angle of ripple design is reasonable, on the basis that the heat exchanger gains higher coefficient of heat transfer, reach reasonable resistance and fall.

Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
Shown in figures 1, 2, 3, 4, 5: the utility model provides a wide passageway welding plate heat exchanger slab of flue gas waste heat recovery, this heat exchanger slab includes a slab main part, the slab main part is the rectangle structure, has horizontal alternative interval arrangement's semicircle trough ripple 1 along horizontal processing in the slab main part, is provided with the outer ripple 2 of V type shallow slot that is the splayed and arranges between two adjacent semicircle trough ripple 1, V type recess on the outer ripple 2 section of V type shallow slot is shallow than the semicircle trough on the ripple 1 section of semicircle trough, two apex angle positions in one side have two first interior supporting point 3, opposite side central point and put and have a second interior supporting point 4 in the slab main part, still are provided with first outer supporting point 5 between two adjacent semicircle trough ripple 1 respectively, and the outer end of every V type shallow slot outer ripple 2 is provided with second outer supporting point 6.
The heat exchange principle is as follows:
the utility model discloses a slab is every two to constitute a slab pair (two slabs of same structure openly and the back (rotate 180 degrees) and detain), and the butt joint straight weld carries out plasma welding or argon arc welding, forms two passageways to the inner chamber (board side) and the outside (shell side) of slab pair, walks two kinds of media respectively, carries out the heat exchange through the heat transfer slab, and the heat transfer medium can be divided into gas-gas, gas-water; the heat exchanger plate material is selected according to the medium passing through, and common materials are 316L, 254SMO, 310S, dual-phase steel and 904L.
