Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of shell-and-tube heat exchanger with filter as shown in Fig. 1~Fig. 2, including housing 1, heat exchanger tube 2, end socket 3
With filtering oar 4；
The heat exchanger tube 2 is fixed in the housing 1, is provided with hot fluid inlet 9 above the housing, lower section is provided with hot-fluid
Body outlet 10, and some deflection plates 8 are there also is provided in the housing 1, hole (not shown) is provided with deflection plate 6 with changing
Heat pipe 2 is socketed；
The end socket 3 is separately mounted to the both sides of the housing 1 by flange 5, and one of them is up provided with cold fluid
Import 6, another is provided with cold fluid outlet 7 in lower section, and the lower section of cold fluid inlet 6 is provided with the filtering oar 4.
As shown in figure 3, the profile of the deflection plate 8 is plectane, and gap, gap are left along the position of wherein one radius
Both ends tilted in the opposite direction along plectane normal direction.
It is rotated by 90 ° as shown in figure 4, the setting angle of the deflection plate 8 is upper a piece of deflection plate 8, and each direction of rotation
It should keep identical.
As shown in figure 5, the filtering oar 4 includes slide rail 11, flow deflector 12 and screen pack 13；The slide rail 11 is annulus
Shape, its inner side are fixed with screen pack 13, and outside is slidably coordinated by the inwall of the track and end socket 3 of projection；The flow deflector
12 be six leaf lodicules, and its marginal portion is vertically welded on slide rail 11.
The screen pack 13 is double-deck (not shown), and upper strata boring ratio lower floor hole is big.
The internal diameter of the heat exchanger tube 2 is 6mm.
Under the conditions of continuous stationary state, turbulent extent is higher, smaller to resistance to heat, and heat transfer coefficient is bigger.
In use, cold fluid flows into from cold fluid inlet 6, flow deflector 12, which wash away, rotates flow deflector 12, improves
The turbulent extent of fluid simultaneously prevents impurity precipitates for a long time from adhering to the bottom of end socket 3, then enters heat exchanger tube 2 simultaneously by screen pack 13
Flowed out from cold fluid outlet 7, heat exchanger tube 2 use small scale Design, internal diameter is only 6mm, thus need simultaneously screen pack 13 prevent because
The inside of heat exchanger tube 2 it is narrow and caused by blocking.Hot fluid flows into from hot fluid inlet 9, passes through the special helical structure of deflection plate 8
The flow velocity of hot fluid within the case 1 is improved, so as to improve fluid turbulent degree, is finally flowed out from hot fluid outlet ports 10, completes to change
Thermal process.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
