Abstract
The utility model relates to a low noise high efficiency sufficient heat exchanger, which comprises a casing provided with a media inlet and a outlet of shell pass, a heat exchange tube and tubeplates at both sides, characterized in that a plurality of small diameter pipes connected with the inside of the tubeplates are fixed on the bottom of the casing; a manifold or a manifold box is connected with the outer end of the small diameter pipe; and the sum of the circulation area of the small diameter pipes is bigger than the designed circulation area of the outgoing pipe. The utility model has the advantages that a plurality of small diameter pipes connected with the inside of the tubeplates are fixed at the outlet of the shell pass so as to avoid the media stagnation at the outlet around the tubeplate; the tubeplates can also exchange heat, so the heat exchange is sufficient with high efficiency; and the possibility of removing the sediment and the scaling.
Description
Technical field
The utility model belongs to a kind of shell-and-tube heat exchanger, the complete heat exchanger of particularly a kind of low-noise high-efficiency.
Background technology
The shell-and-tube heat exchanger of widespread usage in oil, chemical field, shell side steam flows out shell side from outlet, structural design reason owing to tube sheet and outlet, between shell side outlet and tube sheet, one section relative stagnation of space fluid is always arranged, can not participate in heat exchange, vapor-water heat exchanger does not also allow the heat exchange area between shell side outlet and tube sheet be brought into play fully completely effectively, and heat exchanger tube exchange capability of heat is herein significantly reduced.Easily cause simultaneously deposition and fouling.
The utility model content
The purpose of this utility model provides the complete heat exchanger of a kind of low-noise high-efficiency, avoids near the medium of tube sheet in exit to remain in a standstill, and improves heat exchange efficiency, reduce cost, energy savings, tube sheet also can participate in heat exchange, improve heat exchange efficiency, eliminate the possibility of deposition and fouling simultaneously.
The purpose of this utility model is achieved by the following technical solution: it comprises the housing that is provided with shell side medium import and export, heat exchanger tube and two ends tube sheet, it is characterized in that: several small-bore adapters of contact tube sheet inboard are set in shell end, small-bore adapter outer end articulation set pipe or collecting box, small-bore adapter circulation area summation is not less than the design circulation area of discharge connection.So just make the shell side medium can not form relative static triangle dead band with one section space fluid between tube sheet in shell side outlet.Avoided the medium viscous flow, and all fluid has participated in heat transfer work.
The utility model has the advantages that: the small-bore adapter of several contact tube sheet inboards is set at the shell side port of export, avoided near the medium of tube sheet in exit to remain in a standstill, heat exchange is abundant, and tube sheet also can participate in heat exchange, improve heat exchange efficiency, eliminate the possibility of deposition and fouling simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model (an end structure schematic diagram).
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
See Fig. 1,2, concrete structure of the present utility model is as follows: assembling heat exchanger tube 5 in heat exchanger shell 1, at the two ends of housing 1 tube sheet 2 is set, its improved technical essential is: n small-bore adapter 3 of contact tube sheet 2 inboards is set at housing 1 end, 2≤n≤6, small-bore adapter 3 outer end articulation set pipe or collecting box 4, small-bore adapter 3 circulation area summations are not less than the design circulation area of discharge connection.Because small-bore adapter 3 is being pasted tube sheet 2 and is being drawn, not only heat exchanger tube 5 heat exchange, and tube sheet 2 also can participate in heat exchange, significantly improved heat exchange efficiency, also thoroughly solved the problem in viscous flow dead band, facts have proved that this heat exchanger can fully utilize each cun heat exchange area.
Claims (2)
