The modified pitch heat exchanger comprises a tube tank, a tube tank flange, a tube plate, a barrel body flange, a shell pass barrel body, a U-shaped heat exchange tube and a continuous spiral baffle plate. The tube tank is connected with the tube tank flange, and the shell pass barrel body is connected with the tube tank flange. The tube plate is arranged between the tube tank flange and the barrel body flange, and the U-shaped heat exchange tube penetrates through the continuous spiral baffle plate to be fixed with the tube plate. The continuous spiral baffle plate is integral. The tube tank comprises a pass partition plate, a tube pass material inlet and a tube pass material outlet, wherein the pass partition plate is arranged inside the tube tank, the tube pass material inlet is arranged on one side of the tube tank, and the tube pass material outlet is arranged on the other side of the tube tank. The modified pitch heat exchanger has the advantages that modified pitch continuously rotates and flows, the turbulence flow effect is enhanced, a boundary layer is thinned, and the heat transfer efficiency is improved effectively. No dead region exists in continuous rotation and flowing, accumulated dirt is decreased, thermal resistance is stable, the modified pitch heat exchanger is easy to dismantle and maintain, and cleaning of accumulated impurities is facilitated.
Description
Technical field
The utility model relates to coal tar chemical industry coal tar refining field, relates in particular to a kind of modified coal tar pitch heat exchanger.
Background technology
In recent years, along with the Coal Chemical Industry the reach of science, the coal tar refining industrial development is increasingly mature, and modified coal tar pitch more and more is subject to people's attention as a kind of important coal tar refining product.The modified coal tar pitch heat exchanger is heat exchanger important in the coal tar refining industry.Tradition modified coal tar pitch heat exchanger is because dielectric viscosity is large, flow boundary layer is large, causes heat exchange efficiency low, and heat exchange area is large, easily produces the shortcomings such as flow blind angle.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of modified coal tar pitch heat exchanger, reduces flow boundary layer, improves heat exchange efficiency, reduces Impurity deposition.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of modified coal tar pitch heat exchanger comprises bobbin carriage, channel flange, tube sheet, shell flange, shell-side cylinder, U-shaped heat exchanger tube, continuous helical shape baffles, and bobbin carriage is connected with channel flange, and shell-side cylinder is connected with shell flange.Be provided with tube sheet between channel flange and the shell flange, U-shaped heat exchanger tube passes continuous helical shape baffles and tube sheet is fixed.Described bobbin carriage comprises pass partition, tube side material inlet, tube side material outlet, is provided with pass partition in the bobbin carriage, and bobbin carriage one side is provided with the tube side material inlet, and opposite side is provided with the tube side material outlet; Described shell-side cylinder comprises modified coal tar pitch outlet, modified coal tar pitch entrance, saddle, and the shell-side cylinder below is provided with saddle, and modified coal tar pitch outlet, modified coal tar pitch entrance are located at respectively the shell-side cylinder both sides; Described continuous helical shape baffles is a deflection plate.
Compared with prior art, the beneficial effects of the utility model are:
Shell-side fluid (modified coal tar pitch) is rotated continuous-flow, has reduced the Pressure Drop of Fluid Flow in A; The continuous-flow of shell side medium curl has strengthened turbulence effects, attenuate the boundary layer, effectively increased heat transfer efficiency; Continuous rotation flows and does not have the dead band, has reduced the accumulation of dirt, and thermal resistance is stable, and quick detachable, maintenance is conducive to clean the impurity of accumulation.

The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail:
A kind of modified coal tar pitch heat exchanger is seen Fig. 1, comprises bobbin carriage 1, channel flange 4, tube sheet 5, shell flange 6, shell-side cylinder 7, U-shaped heat exchanger tube 10, continuous helical shape baffles 13.Bobbin carriage 1 is connected with channel flange 4, and shell-side cylinder 7 is connected connection with shell flange.Be provided with tube sheet 5 between channel flange 4 and the shell flange 6.It is fixing with tube sheet 5 that U-shaped heat exchanger tube 10 passes continuous helical shape baffles 13.Described bobbin carriage 1 comprises pass partition 12, tube side material inlet 2, tube side material outlet 3, is provided with pass partition 12 in the bobbin carriage 1, and bobbin carriage 1 one sides are provided with tube side material inlet 2, and opposite side is provided with tube side material outlet 3; Described shell-side cylinder 7 comprises modified coal tar pitch outlet 8, modified coal tar pitch entrance 9, saddle 11, and shell-side cylinder 7 belows are provided with saddle 11, and modified coal tar pitch outlet 8, modified coal tar pitch entrance 9 are located at respectively shell-side cylinder 7 both sides; Described continuous helical shape baffles 13 is a deflection plate.
The tube side medium is entered by tube side material inlet 2, is left by tube side material outlet 3.The shell side modified coal tar pitch is entered by modified coal tar pitch entrance 9, is left by modified coal tar pitch outlet 8.The shell side modified coal tar pitch forms spiral, uniform runner between continuous helical shape baffles, effectively improved heat exchange efficiency.
The utility model makes modified coal tar pitch form spiral, uniform runner between continuous helical shape baffles.Helical flow has improved its turbulent extent, attenuate the boundary layer of flowing, reduced heat transmission resistance, thereby improved heat exchange efficiency, reduce heat exchange area, equipment volume descends thereupon, so that its construction cost reduces greatly.Helical flow has also been avoided the serious pressure loss of horizontal baffling generation, effectively reduces the Pressure Drop of media flow.And continuous rotation flows and does not have the dead band, has reduced the accumulation of dirt, and thermal resistance is stable, can make heat exchanger be in efficient running status always, and quick detachable, the maintenance of this heat exchanger is conducive to clean the impurity of accumulation.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions.Everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
