Abstract
The utility model provides an air heat exchanger, which can carry out heating air. The utility model comprises box bodies 1, 2, a guide current box 3, a heat exchanger plate 4 and a cold and a hot channels 5, 6 which are formed by the heat exchanger plate 4. The utility model can be realized mainly by that the cold and hot channels 5, 6 with different flow sections are arranged, folded plates 7 which are mutually vertical are arranged between the cold and the hot channels, and the box bodies 1, 2 are movably connected with the guide current box 3. The utility model has the advantages of simple and reasonable design and structure and easy fabrication and use; the utility model is not only convenient to be cleaned, but also the crystallization of tar in the hot passage 6 can be reduced, the heat efficiency can be effectively enhanced, etc.
Description
The utility model relates to a kind of to grain, timber, asbestos, slag, schlempe etc. are dried and dewatering vegetable uses air heat-exchanging device.
Hot and cold passage that the flow area that the heat exchanger plates that existing air heat exchanger is provided with by inside is formed equates and the guide tank of fixedlying connected with outer case constitute.Heat exchanger plates upper punch at this heat exchanger is pressed with several crisscross semicircle raised strip and depressions, and corresponding two projectioies support relatively in each passage.Processing technology complexity not only, and owing to enter the fuel gas temperature higher (generally about 1000 ℃) of passage of heat inlet, under the high temperature heat exchanger plates very easily is out of shape, also contain a large amount of tar in the combustion gas and dust easily adheres to, must regularly clean, otherwise influence the thermal efficiency, it is also not quite convenient to clean.
The purpose of this utility model is to provide a kind of manufacturing process easy, and at high temperature its heat exchanger plates is not yielding, the air heat exchanger that easy cleaning and heat exchange efficiency are high.
The technical solution of the utility model is as described below: this utility model comprises casing, guide tank, the hot and cold passage that forms between heat exchanger plates and the heat exchanger plates, by the hot and cold passage that flow area does not wait is set, the flexible connection of the orthogonal flap of hot and cold interchannel and casing and guide tank realizes.
This utility model is owing to taked to increase the flow area of thermal medium, structures such as flap in the hot and cold passage are set, make it have the project organization advantages of simple, make easy to use, not only be convenient to clean but also can reduce tar, effectively improve advantages such as the thermal efficiency at passage of heat intercrystalline.
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further details:
Fig. 1 is the overall structure schematic diagram of air heat exchanger;
Fig. 2 is the A-A cutaway view of air heat exchanger;
Fig. 3 is the B-B cutaway view of air heat exchanger.
By Fig. 1-air heat exchanger shown in Figure 3 is improved air heat transmission equipment on the prior art basis.Its high-temperature hot air 500-1000 ℃ use suitable and coking of configuration inlet.The outside of this utility model is flexibly connected through flange, pad and bolt by the guide tank of two casings arranged side by side 1,2 and its bottom (in establish deflector) 3.In casing 1,2 and the guide tank 3 heat-insulation layer is set all.Being provided with the heat exchanger channels of forming between the heat exchanger plates 4 of vertical arrangement and the heat exchanger plates 4 in the casing 1,2 is hot and cold passage 5,6, the medium passing cross section is slightly larger than cold medium flow area in two passages 5,6, can find out obviously that by Fig. 2, Fig. 3 purpose is to reduce crystallization and improves the thermal efficiency.It is slightly big or small because interior flow area is different for the flap 7 in flap 7, two passages 5,6 of " people " font to be evenly distributed with the mode cross section on the heat exchanger plates 4 of hot and cold passage 5,6, and is vertically welded in mutually on the heat exchanger plates 4, to form firm support.Can effectively prevent high temperature friendship shape.
During work, thermal medium enters heat exchanger from casing 1 top inlet, enters the guide tank 3 that the bottom connects through the inner passage, is discharged to casing 2 and by casing 2 top exits by guide tank 3.And cold air connects inlet by the flange of casing 1 one sides and enters heat exchanger; In cold passage 5, carry out cold and hot air exchange, send utilization from the outlet of casing 2 opposite side flanges again.
Claims (2)
1, a kind of air heat exchanger, comprise the hot and cold passage (5), (6) that form between casing (1), (2), guide tank (3), heat exchanger plates (4) and the heat exchanger plates (4), it is characterized in that: the flow area of hot and cold passage (5), (6) is a unequal section, establish flap (7) and vertical mutually the setting in hot and cold passage (5), (6), casing (1), (2) flexibly connect with guide tank (3).
2, air heat exchanger according to claim 1 is characterized in that: the cross section of passage (5), (6) interior flap (7) is " people " font.
