Abstract

The invention relates to a tar heat exchanger in the coke chemical industry. The tar heat exchanger comprises a pipe header, a pipe pass material inlet, a pipe pass material outlet, a shell pass cylinder body, a tar inlet, a tar outlet and a plurality of heat-exchanging pipes, and is characterized in that the heat-exchanging pipes are bidirectional spiral flat heat-exchanging pipes which are fixed between pipe plates at two sides of the shell pass cylinder body, and contact parts among the bidirectional spiral flat heat-exchanging pipes constitute point supporting structures; and shell passes are continuous flow channels among the plurality of bidirectional spiral flat heat-exchanging pipes. A flow guiding cylinder is arranged in the shell pass cylinder body and constitutes a sealed continuous flow channel in the shell pass cylinder body together with baffles at two sides. The heat exchanger has the advantages of high heat-exchanging efficiency, no transverse baffle, no accumulated tar impurities in the shell passes, convenience for dismounting and cleaning, and small occupied floor area, and has greater superiority when being applied to tar heat exchanging.

Description

A kind of new and effective tar heat exchanger
Technical field
The present invention relates to the novel tar heat exchanger in a kind of coal tar chemical industry, specifically is a kind of tar heat exchanger that adopts the bidirectional screw flat heat exchange tube.
Background technology
The tar heat exchanger is a heat exchanger important in the coal tar chemical industry.The heat exchanger tube of conventional coke tar heat exchanger adopts the straight tube tube bank more, and this structure exists heat exchange efficiency low, and shell side tar impurity is piled up, shortcomings such as difficult cleaning.
Therefore, study that a kind of heat exchange efficiency is high, to pile up the few tar heat exchanger of impurity be the present technical issues that need to address to shell side tar.
Summary of the invention
The purpose of this invention is to provide a kind of tar heat exchanger, this heat exchanger heat exchange efficiency is high, no baffle plate, and shell side tar impurity does not have accumulation, is convenient to disassembly, cleaning, and floor space is little, is applied to have bigger advantage in the tar heat exchange.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of tar heat exchanger; Comprise bobbin carriage, tube side material inlet, tube side material outlet, shell-side cylinder, tar inlet, tar outlet, heat exchanger tube; It is characterized in that; Described heat exchanger tube is that several bidirectional screw flat heat exchange tubes are fixed between the tube sheet of shell-side cylinder both sides, and the contact site between the bidirectional screw flat heat exchange tube constitutes the some supporting construction; Shell side is continuous runner between several bidirectional screw flat heat exchange tubes.
Be provided with guide shell in the described shell-side cylinder, guide shell and two side shields are formed airtight continuous runner in shell-side cylinder.
Compared with prior art, tar heat exchanger of the present invention has following advantage:
1, spiral flat tube heat exchanger tube bidirectional screw is arranged; Tar in the shell side forms complicated bidirectional screw, uniform runner between the bidirectional screw flat tube; Flowing velocity is increased, and helical flow has also improved its turbulent extent, attenuate the boundary layer of flowing; Reduce heat transmission resistance, thereby improved heat exchange efficiency.
2, because the raising of heat exchange efficiency reduces heat exchange area, and equipment volume descends thereupon, this heat exchanger no baffle plate makes its construction cost reduce greatly in addition.
3, because the interior no baffle plate of shell side relies on mutual support of the spiral outer rim formation of spiral flat tube point contact, so eliminated the flow dead in the shell side between the heat exchanger tube, reduced the pressure drop of tar.
4, because the shell side inner flow passage is the shaped form continuous passage, non-blind area, the helical structure of spiral flat tube make fluid inside and outside pipe, form stronger eddy current, and eddy current is constantly washing away wall, and therefore, this heat exchanger is less scaling.
5, the supporting construction of the uniqueness of spiral flat tube can form higher flow velocity in shell side, thereby has also reduced the accumulation of impurity in the tar.

The specific embodiment
Be described in detail the structure and the course of work of tar heat exchanger below through the specific embodiment.
The operation principle of tar heat exchanger is: the space between the shell side bidirectional screw flat heat exchange tube 10 is the tar runner; The tar fluid is got into by tar inlet 9; Discharge by tar outlet 8; The tar fluid between bidirectional screw flat heat exchange tube 10 with heat exchanger tube in medium carry out heat exchange, finally reach and improve heat exchange efficiency, reduce effect such as impurity deposition.
The structure of tar heat exchanger comprises bobbin carriage 1, tube side material inlet 2, tube side material outlet 3, channel flange 4, fixed tube sheet 5, shell flange 6, shell-side cylinder 7, tar outlet 8, tar inlet 9, spiral flat tube heat exchanger tube 10, saddle 11, shell flange 12, floating tubesheet 13, outer skull flange 14, outer skull 15, pass partition 16, hook circle 17, Floating Head Flange 18, floating head 19, guide shell 20, baffle plate 21.Several bidirectional screw flat heat exchange tubes 10 are fixed between the tube sheet of shell-side cylinder 7 both sides, and the contact site between the bidirectional screw flat heat exchange tube 10 constitutes some supporting construction 22; Shell side is continuous runner between several bidirectional screw flat heat exchange tubes.
Bobbin carriage 1 is connected with channel flange 4, is provided with pass partition 16 in the bobbin carriage 1 tube side is divided into multipass, confirms tube side quantity as the case may be.Tube side material inlet 2, tube side material outlet 3 are separately positioned on bobbin carriage, and about in the of 1 both sides.Shell-side cylinder 7 both sides are connected with shell flange 6, shell flange 12 respectively, and the below of shell-side cylinder 7 is provided with saddle 11.Tar outlet 8, tar inlet 9 are separately positioned on the both sides of shell-side cylinder 7.
Fixed tube sheet 5 is arranged between channel flange 4 and the shell flange 6, and floating tubesheet 13 places between hook circle 17 and the Floating Head Flange 18.Floating Head Flange 18 is arranged at floating head 19 outsides, and outer skull 15 is connected with outer skull flange 14.Spiral flat tube heat exchanger tube 10 is fixed between fixed tube sheet 5 and the floating tubesheet 13.The tube side medium is got into by tube side material inlet 2, is discharged by tube side material outlet 3.Guide shell 20, baffle plate 21 are formed airtight runner in shell-side cylinder 7, shell side tar is got into by tar inlet 9, are discharged by tar outlet 8.Flow uniformly in the complicated bidirectional screw runner that shell side tar forms between the bidirectional screw flat heat exchange tube, improved heat exchange efficiency greatly.
