Specific embodiment
Combined with specific embodiments below and attached drawing is described further the technical solution of the utility model.
As shown in Fig. 2, embodiment 1 discloses a kind of plate type heat exchange piece (i.e. heat exchange plate), by the board-like of traditional form
The flanging direction of (plate pattern) Heat exchanger sheet improves, by tradition non-conterminous two just, non-conterminous two Turn up hem is changed to
Two Turn up hem of adjacent two just, adjacent.
By two panels plate type heat exchange piece described in embodiment 1 is stacked and adjacent two positive flanging docks and welds together, thus
Constitute a heat exchanger plates beam.The adjacent both sides of the heat exchanger plates beam are closed, another both sides intercommunication, constitute one can supplied gas flowing the
One medium channel.It is repeated with this, each plate type heat exchange piece is welded into combination two-by-two, form multiple heat exchanger plates beams, each heat exchanger plates beam
With a first medium channel.Two heat exchanger plates beams are staggered relatively, and by plate-type heat-exchange opposite in two heat exchanger plates beams
Adjacent two Turn up hem of piece is docked and is welded together, the adjacent both sides closing of two heat exchanger plates beams, another both sides intercommunication, structure
At one can supplied gas flowing second medium channel.It is repeated with this, each heat exchanger plates beam is arranged successively, adjacent two boards formula heat exchange
Piece welding combination, to constitute the heat exchanger core body of plate heat exchanger.The heat exchanger core body have multiple first medium channels and
Second medium channel, and first medium channel and second medium channel are not connected.
Wherein, the hem dimensions of adjacent two positive flangings and two Turn up hem mainly by cold and hot two sides gas air quantity and required change
Drag losses that heat area and system can provide determine, hem dimensions can non-standard de-sign, be not fixed.Flanging width generally takes
Between 6-15mm, that is to say, that medium channel will not both be changed generally between 12-30mm due to the excessive influence in plate channel in this way
Thermal effect, while compressed air or high pressure water also being facilitated to carry out flush clean to channel plate.It should be noted that positive Turn up hem
Width can be different, and corresponding first medium channel and second medium channel width can also be different, but all first mediums are logical
The width in road is consistent, and the width in all second medium channels is also consistent.In view of plate is excessively thin, entirely welded in manufacturing process
Difficulty is too big, and plate is too thick and flanging is again small, and difficulty increases in flanging pressing process, and therefore, sheet is generally 0.5-
Between 1.5mm, 0.7-1.2mm is best.
In conjunction with shown in Fig. 3 and Fig. 4, embodiment 2 discloses a kind of piping or plate heat exchanger easy for installation (hereinafter referred to as
Plate heat exchanger), belong to waste heat recycling field, mainly include heat exchanger core body, gas inlet 3, exhanst gas outlet 1, air into
Mouth 5 and air outlet slit 4.
The heat exchanger core body is welded to form by multiple plate type heat exchange pieces 2 described in embodiment 1, the flanging side of heat exchange plate 2
It is just being rolled over and two adjacent reflexeds to for adjacent two.So that by the adjacent two positive folding direction of heat exchanger after plate welding combination
Channel intercommunication, channel intercommunication on adjacent two Turn up hem and combines that form channel completely obstructed with above-mentioned two positive flangings welding.
The gas inlet 3 of the plate heat exchanger, which is arranged with 1 vertical direction of exhanst gas outlet and connect the first of heat exchange plate 2, to be situated between
Matter channel is formed dust-laden hot fume channel (abbreviation exhaust gases passes), that is, the one side in the just folding direction channel of heat exchange plate 2 two is (short
Side) connection gas inlet 3, another positive flanging (long side) connection exhanst gas outlet 1 adjacent thereto.Air intlet 5 and air outlet slit 4
Also vertical direction is arranged, and connects the second medium channel of heat exchange plate 2, and forming hot-gas channel to be added, (abbreviation air is logical
Road), that is, the one side (short side) in 2 two reflexed direction channel of heat exchange plate connects air intlet 5, another Turn up hem adjacent thereto
(long side) connects air outlet slit 4.
By this design, cold and hot side liquid inlet and outlet direction is not in same direction and vertical design, and import and export institute
Side be selection long side or short side be not intended to limit, can be arranged according to process system demand.Exhanst gas outlet 1 and air go out
Mouth 4 can be directly connected to piping, and size can be according to piping demand production, but should not exceed the 1/3 of its place side plate leaf length, and
Cold and hot two sidewinds trend is better closer to adverse current, in order to avoid there is the case where part plate exchanges heat in vain.Because hot and cold gas are inverse
It flows away to helping to conduct heat, is open too big, gas is easy short circuit, leads to that entire heat exchanger plates cannot be evenly arranged.
Be horizontal direction in the duct orientation for requiring exhanst gas outlet to connect with air outlet slit, and hot fume be it is enterprising, it is cold
Air be under into waste heat reclaiming process in, using this plate heat exchanger, exhanst gas outlet is determined according to the size of docking nozzle
1 and air outlet slit 4 flange size, the channel that two positive flangings are formed in heat exchange plate 2 in equipment making connects exhanst gas outlet 1
Side welded connecting plate when reserve the size of exhanst gas outlet 1, and assemble 1 flange of exhanst gas outlet；Two reflexeds in heat exchange plate 2
The size of air outlet slit 4 is reserved when the side welded connecting plate for the channel connection air outlet slit 4 that side is formed, and assembles air and goes out
4 flanges of mouth；Exhanst gas outlet 1 is directly connected by bolt with pipe flange with air outlet slit 4, realizes exhanst gas outlet 1 and air
Export 4 connecting pipe directions in the horizontal direction.
In conjunction with shown in Fig. 1 and Fig. 3, by the plate heat exchanger of the utility model design compared with traditional plate heat exchanger:
It can clearly be seen that scheme as described in example 2 is simpler than traditional scheme form many and easy to manufacture and install, volume
It is obvious much smaller.In addition, though traditional scheme shown in FIG. 1 also can satisfy process requirement, but equipment is than cumbersome, cost
Height, and two elbow-makings designed and installation are all inconvenient, space hold is big, while the elbow designed also will increase equipment
Pressure drop.And scheme shown in embodiment 2 is then avoided that the above problem, while meeting process requirement, reduces equipment volume,
Reduce production and installation cost.
Although the embodiments of the present invention are described in conjunction with attached drawing above, the utility model does not limit to
In above-mentioned specific embodiments and applications field, above-mentioned specific embodiment is only schematical, directiveness, without
It is restrictive.Those skilled in the art under the enlightenment of this specification, are not departing from the utility model claims
In the case where the range protected, a variety of forms can also be made, these belong to the column of the utility model protection.
