Abstract
The invention relates to a spiral-plate heat exchanger which aims to solve the problems that a welding part of a spiral heat exchange plate of a current spiral-plate heat exchanger and a partition plate is relatively great in stress and is easy to block, and the manufacturing cost is relatively high. According to the spiral-plate heat exchanger, inner spiral ends of two spiral heat exchange plates which are arranged at intervals are connected through one partition plate, and the partition plate is used for dividing a gap between the two spiral heat exchange plates into two spiral cold and heat channels; upper and lower ends of the cold and heat channels are sealed; inner and outer spiral ends of the cold and heat channels are connected to an inlet and an outlet of cold and heat media; the two spiral heat exchange plates and the partition plate are integrated, and are made of the same block material. The two spiral heat exchange plates and the partition plate are once rolled and formed by the same block material, so that the manufacturing process is simple, the cost is low, the stress is relatively low, damage is not easily caused, and the leakage problem is avoided.
Description
Technical field
The present invention relates to a kind of spiral-plate heat exchanger.
Background technology
In existing spiral-plate heat exchanger, the inside spin end of the spiral heat exchange plate that two is intervally arranged is connected by a dividing plate, gap between two spiral heat exchange plates is divided into two spiral helicine hot and cold passages by dividing plate, the upper and lower side of hot and cold passage by shutoff, the inside and outside spiral end of hot and cold passage connect respectively cold. the import and export of thermal medium.Two spiral heat exchange plates and dividing plate system three blocks of sheet materials are made, and the inside spin end of two spiral heat exchange plates welds mutually with dividing plate respectively.
Because the inside spin end of two spiral heat exchange plates welds mutually with dividing plate, their junction stress is comparatively large, under the effect of the hot and cold medium of medium-pressure or high pressure, is easy to be damaged; And due to welding quality, the easy seepage in junction; In addition, owing to there being two weld seams to need welding, manufacturing process is complicated, and cost is higher.
Summary of the invention
The technical problem that the present invention solves is exactly that the weld stress of the spiral heat exchange plate of existing spiral-plate heat exchanger and dividing plate is more fragile, easy to leak, the problem that manufacturing cost is higher.
Spiral-plate heat exchanger of the present invention, the inside spin end of the spiral heat exchange plate 1,2 that two is intervally arranged is connected by a dividing plate 8, and the gap between two spiral heat exchange plates 1,2 is divided into two spiral helicine hot and cold passages 3,4 by dividing plate 8, cold,
The upper and lower side of the passage of heat 3,4 by shutoff, the import and export of the hot and cold medium of inside and outside spiral termination of hot and cold passage 3,4; Two spiral heat exchange plates 1,2 and dividing plate 8 are integrated, and are that same sheet material is made.Because two spiral heat exchange plates 3,2 and dividing plate 8 are integrated, be that same sheet material is made, there is no weld seam, under the effect of the hot and cold medium of medium-pressure or high pressure, be not easy to be damaged; Also there will not be leakage problems; In addition, owing to being same sheet material roll-forming, manufacturing process is simple, and cost is low.
As further improvement, two spiral heat exchange plates ", the lower end of 2 is on a conical surface.This kind of structure, makes the hot and cold media flow speed in the lower end of hot and cold passage, there will not be hot and cold medium " alluvial " phenomenon, effectively can improve heat exchange efficiency like this.
For any one spiral-plate heat exchanger recited above, the upper end of hot and cold passage 3,4 be can be by the structure of shutoff: the upper end of two spiral heat exchange plates 1,2 becomes to be tightly connected with between upper cover plate, it can be removably connect that sealing connects, and may also be non-dismountable connection.The advantage removably connected is, upper cover plate can be pulled down, and thoroughly cleans hot and cold passage 3,4.For any one spiral-plate heat exchanger recited above, be provided with the stiffener 9 fitted with the surface of dividing plate 8 and spiral heat exchange plate 1 in the inner side that dividing plate 8 connects with spiral heat exchange plate 1.
For any one spiral-plate heat exchanger recited above, be provided with the stiffener 10 fitted with the surface of dividing plate 8 and spiral heat exchange plate 2 in the inner side that dividing plate 8 connects with spiral heat exchange plate 2.
Stiffener 9 or 10 is set in the inner side that dividing plate 8 connects with spiral heat exchange plate 1 or 2 and plays supplementary booster action, increase the intensity at this place, make it more safe and reliable.
For any one spiral-plate heat exchanger recited above, when the import of the cold medium of inside spin termination of cold passage 3, the outlet of the inside spin termination thermal medium of the passage of heat 4.This makes the hot and cold medium reverse flow in hot and cold passage 3,4, makes heat transfer effect better.
Accompanying drawing explanation
Fig. 1 is the schematic diagram (the A-A sectional view of Fig. 2) of a kind of embodiment of the present invention;
Fig. 2 is the B-B sectional view of Fig. 1.
Detailed description of the invention
Spiral-plate heat exchanger shown in Fig. 1,2, the inside spin end of the spiral heat exchange plate 1,2 that two is intervally arranged is connected by a dividing plate 8.Two spiral heat exchange plates 1,2 and dividing plate 8 are integrated, and are that same sheet material is made.Because two spiral heat exchange plates 1,2 and dividing plate 8 are integrated, be same sheet material roll-forming, manufacturing process is simple, and cost is low; Stress is less, is not easy to damage;
Also there will not be leakage problems.
The stiffener 9 fitted with the surface of dividing plate 8 and spiral heat exchange plate 1 is provided with in the inner side that dividing plate 8 connects with spiral heat exchange plate 1.The stiffener 10 fitted with the surface of dividing plate 8 and spiral heat exchange plate 2 is provided with in the inner side that dividing plate 8 connects with spiral heat exchange plate 2.
Gap between two spiral heat exchange plates 1,2 is divided into two spiral helicine hot and cold passages 3,4 by dividing plate 8.The lower end of cold passage 3, the passage of heat 4 is welded on helical form round steel 13,14 shutoff of bottom between spiral heat exchange plate 1,2 respectively.
The lateral surface on the top of two spiral heat exchange plates 1,2 is provided with flange 6, and flange 6 is removably connected by 7 one-tenth, bolt with upper cover plate 5, is and is tightly connected between the upper end 11 of upper cover plate 5 and spiral heat exchange plate 1, the upper end 12 of spiral heat exchange plate 2.When needs thoroughly clean hot and cold passage 3,4, upper cover plate 5 can be pulled down from flange 6, clean.
The lower end of two spiral heat exchange plates 1,2 is on a conical surface 16.This makes the hot and cold media flow speed in hot and cold passage lower end, especially the hot and cold media flow speed in the hot and cold passage of the inside spin end the closer to spiral heat exchange plate is faster, as shown in FIG., because cold passage 17 place is than the inside spin end of cold passage 15 place closer to spiral heat exchange plate, so cold passage 17 place is faster than the cold media flow speed at cold passage 15 place.
The inside spin end bottom of the passage of heat 4 connects the outlet 18 of thermal medium; The inside spin end bottom of cold passage 3 connects the import 19 of cold medium.Connect the import 20 of thermal medium in the middle part of the external spiral end of the passage of heat 4, in the middle part of the external spiral end of cold passage 3, connect the outlet 21 of cold medium.This makes the hot and cold medium reverse flow in hot and cold passage 3,4, and heat transfer effect is better.
