Fig. 2 is the schematic side view of steamer bled steam hydrothermal exchange recover described in the utility model;
Fig. 3 is the external annexation schematic diagram of steamer bled steam hydrothermal exchange recover shown in Figure 1.
The specific embodiment
Now in conjunction with the accompanying drawings the specific embodiment of the present utility model is described in detail.
As illustrated in fig. 1 and 2, a kind of steamer bled steam hydrothermal exchange recover K comprises housing, and described housing is provided with and reclaims hot water outlet 1, water inlet 4, air inlet 8, exhaust outlet 5, and distilled water outlet 6.Water pipe 7 is installed in the described housing, it can be made by aluminium, stainless steel, iron, copper, silver and plastic cement etc., water pipe 7 can adopt clockwise or counterclockwise coiling mode, can be rule or irregular shape after the coiling, in addition, water pipe 7 can be an individual tubes, also can be entwined mutually by many branch branching pipes, its caliber magnitude range can be 5mm～200mm, self length range can be 0.5m～100m, the coiling length range can be 0.3m～50m, can decide as the case may be.The water inlet end of water pipe 7 is communicated with described water inlet 4, and the water side is communicated with described recovery hot water outlet 1.
In order to avoid inside and outside portion to carry out exchange heat to greatest extent, described housing comprises the thermal wall of hollow structure, and described thermal wall comprises outer wall 10, inwall 12, and the insulation layer between the two 2.Described outer wall 10 and inwall 12 can be made by aluminium, stainless steel, iron, copper, silver and plastic cement etc.; Described insulation layer 2 can use disconnected heat cotton, pearl is cotton or foamed material etc. filled, and perhaps it is evacuated.In the present embodiment, insulation layer 2 is pumped into vacuum, therefore, connects a vacuum extractor 3 that is communicated with insulation layer 2 on outer wall 10.
For the ease of processing, described housing not exclusively is made up of thermal wall, but comprise thermal wall and the left thermal baffle 9 and the right thermal baffle 13 that are fixedly mounted on the thermal wall two ends, described left thermal baffle 9 and right thermal baffle 13 can wrapped up in disconnected heat cotton by metallic plate, pearl is cotton or other insulation materials are made, also can make, can play heat insulation effect equally of resistant to elevated temperatures offset plate.If the bottom that air inlet 8 is arranged on thermal wall is near on the position of left end, between then described left thermal baffle 9 and the thermal wall for being tightly connected, and exhaust outlet 5 is arranged on the right thermal baffle 13, so can prevent the bled steam that enters from air inlet 8 not with water pipe 7 in water carry out heat exchange and just directly discharge from left thermal baffle 9, can not recycle heat energy fully.
In addition, because water pipe 7 can form a hollow channel at the middle part after coiling, the bled steam that enters from air inlet 8 has greatly and will flow through from hollow channel, discharge from exhaust outlet 5 again, because bled steam is the process of flowing through from hollow channel, have only the part of relatively pressing close to water pipe 7 could be preferably with water pipe 7 in water carry out heat exchange, and near a part of bled steam the hollow channel center line also is not absorbed heat and just discharges from exhaust outlet 5, has reduced energy utilization ratio.For the heat that bled steam is contained can be utilized fully, one steam guiding device 11 can be set in housing, described water pipe 7 twines thereon, bled steam is flowed in the less clearance between water pipe 7 and the inwall 12, and in the less clearance between water pipe 7 and the steam guiding device 11, guarantee that the cold water in the water pipe 7 can carry out sufficient heat exchange with bled steam.Described steam guiding device 11 also can be hollow structure, and near the sealing of an end of air inlet 8 (prevent bled steam from directly discharging) from the hollow channel of water pipe, the other end can opening, described steam guiding device 11 can be cylinder, pyramid or prism etc., and the coiling length of length and water pipe 7 quite gets final product.
Reclaim the left end that hot water outlet 1 can be arranged on thermal wall, water inlet 4 is arranged on the right-hand member of thermal wall.From reclaiming the hot water after cold and hot exchange that hot water outlet 1 flows out, in being used for steamer the feedwater, can also be used to wash the dishes and shower etc.The water that bled steam condenses into after cold and hot exchange is flowed out by distilled water outlet 6.A part is not carried out the bled steam of heat transmission and is discharged from exhaust outlet 5.
Steamer bled steam hydrothermal exchange recover K to external link structure as shown in Figure 3, the outlet of the air inlet 8 of steamer bled steam hydrothermal exchange recover K and the bled steam of steamer steam room F (can comprise a plurality of steam rooms) is communicated with; Water inlet 4 is communicated with the cold water ascending pipe; Reclaim hot water outlet 1 and insert total hot water supply line A by reclaiming hot water effluent's pipeline B; Total hot water supply line A can be communicated with each minute hot water supply pipe I and hot water return pipe road C; Whether the hot water in the water-suppling electromagnetic valve D control hot water backflow conveyance conduit C flows into steamer water vat H; Distilled water outlet 6 is communicated with steamer water vat H by distilled water reflux line E, in order to prevent that distilled water is back to steamer steam room F by air inlet 8, can plate washer 14 be set in a side of the contiguous distilled water outlet 6 of air inlet 8, the shape of baffle plate 14 is by the shape decision of steamer bled steam hydrothermal exchange recover K, and the height of baffle plate 14 can not prevent that bled steam from flowing to exhaust outlet 5 from the bottom of water pipe 7; The steam that the steamer water vat produces enters steamer steam room F by steam pipe G.
The operation principle and the process of described steamer bled steam hydrothermal exchange recover are as follows:
At first, toward the interior topped up with water of steamer water vat H, when treating that water temperature rises to uniform temperature, air inlet 8 has bled steam to flow into, and bled steam carries out heat transmission along steam guiding device 11 and water, according to the principle of heat transmission, bled steam transmits heat for the water of low temperature by water pipe 7, and water temperature is raise; Simultaneously, bled steam is condensed into water attached on water pipe 7 or the inwall 12, along with the water of condensation is more and more, distilled water outlet 6 just has distilled water and flows back to steamer water vat H by distilled water reflux line E, the heat that distilled water had accounts for 15%～30% of bled steam heat, distilled water is back to steamer water vat H can saves about 10%～30% heat energy, using water wisely about 20%～60%.
Because the distilled water deficiency is thought steamer water vat H moisturizing, the hot water in the water pipe 7 can flow back among the steamer water vat H through hot water return pipe road C by control water-suppling electromagnetic valve D, and the water yield among the steamer water vat H is maintained in certain scope; This part hot water that is back among the steamer water vat H can reduce because of the required energy that expends of heating cold water, saves about 10%～40% heat energy.In addition, the hot water in the water pipe 7 can also be fed to the occasion that needs with hot water by minute hot water supply pipe I, has saved to add the heat energy that hot water need expend.
Utilize steamer bled steam hydrothermal exchange recover constantly to carry out recycling, saved energy and water resource greatly bled steam, not only economy but also environmental protection, hot-water supply has been saved the time in real time.
In addition; above-mentioned embodiment is not to be steamer bled steam hydrothermal exchange recover described in the utility model and to the restricted embodiment of external link structure; modification or equivalent deformation that all those skilled in the art are carried out on the basis of the utility model flesh and blood all are interpreted as belonging to protection domain of the present utility model.
