Abstract

The utility model discloses an anti-blocking shell-and-tube heat exchanger with multiple tube bundles, which comprises a shell, the tube bundles, pup joints, reducers, tube flanges, 180-degree bends, tubular plates, heat exchange tubes, baffle plates and the like. Two adjacent tube bundles are connected to form a passage to replace a tube box of a conventional heat exchanger by the aid of the 180-degree bends, so that a structure of multiple tube bundles is formed, flow dead zone in the tube box is eliminated, and deposition of media in the tube box can be avoided. Turbulent flow level of fluid is improved, time for the media staying in heat exchange tubes is shortened, and firm fouling on the inner surfaces of the heat exchange tubes and formed by loosened impurities can be avoided. Accordingly, heat transfer efficiency is improved, and long-term stable running of the shell-and-tube heat exchanger is guaranteed.

Description

Multitubular bundles anti-clogging shell-and-tube heat exchanger
Technical field
The utility model relates to a kind of multitubular bundles anti-clogging shell-and-tube heat exchanger, is applicable on the heat-exchanger rig in fields such as chemical industry, light industry, food, and being particularly useful for tube side fluid is the occasion that contains solid particle, easy fouling or gluey easily stifled medium.
Background technology
All there is certain flow dead in the bobbin carriage of conventional shell-and-tube heat exchanger, when tube side fluid is easily blocked up medium for containing solid particle, easy fouling or glue, because the effect of gravitational settling, adhesion etc., impurity in the medium will slowly deposit in heat exchanger tube and in the dead band of bobbin carriage, on the one hand, the heat exchanger circulation area is reduced, dirtiness resistance increases, the heat-transfer effect variation has increased the energy consumption of whole device; On the other hand, the workload of cleaning heat exchanger increases, and overhaul of the equipments becomes frequently, also can cause the obstruction of whole heat exchanger when serious, directly has influence on the safe and stable operation of device.
Summary of the invention
The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of multitubular bundles anti-clogging shell-and-tube heat exchanger with not enough.
The purpose of this utility model is achieved through the following technical solutions:
A kind of multitubular bundles anti-clogging shell-and-tube heat exchanger comprises housing, tube bank, pipe nipple, reducer pipe, pipe flange, 180 ° of elbows, tube sheet, heat exchanger tube and deflection plates.
180 ° of elbows are connected to form path with two adjacent tube banks, substitute the bobbin carriage of traditional heat exchangers, realize the multitubular bundles structure, eliminate the flow dead in the bobbin carriage, avoid medium to deposit in bobbin carriage; Improve the turbulent extent of medium, shorten the time of staying of medium in heat exchanger tube, prevent that the loose impurity that is deposited on the heat exchanger tube inner surface from forming firm dirt; Improve the heat transfer efficiency of heat exchanger, guaranteed the long-term stability operation of equipment.
Heat exchanger tube is fixed on the tube sheet, and heat exchanger tube is made of some tube banks.Adjacent two tube banks connect into path by 180 ° of elbows.The effect of tube bank is to make minor diameter heat exchanger tube energy and major diameter elbow form path, avoids using the major diameter heat exchanger tube with heat transfer coefficient that reduces heat exchanger and the volume that increases equipment.
Two adjacent tube banks are fixed on the tube sheet with pipe nipple, and fixing mode can be used welding, flange connection etc., preferably uses welding, and welding can reduce distance between restraining with the saving space.Pipe nipple is connected with 180 ° of elbows with pipe flange successively by reducer pipe, has constituted a path.
In the junction of tube bank and elbow, adopt the reducer pipe transition, dwindle elbow diameter, further improve flow velocity, shorten the time of staying of medium in the elbow.Shell side is provided with some deflection plates to increase the turbulent extent of fluid, improves the heat transfer coefficient of fluid.By above measure, can improve the turbulent extent of fluid, eliminate the dead band in bobbin carriage and the heat exchanger tube, guarantee the long-term stability operation of heat exchanger.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
Multitubular bundles anti-clogging shell-and-tube heat exchanger is based on traditional shell-and-tube heat exchanger.As shown in Figure 1, housing 1 and deflection plate 9 are structurally basic identical with traditional shell-and-tube heat exchanger, and tube sheet 7 adopts thin tubesheet to be welded in the cylindrical shell.In the tube side heat exchanger tube is divided into some tube banks 2.Arranging by the pattern of equilateral triangle between heat exchanger tube in the tube bank, tube bank and the tube bank is fixed on the tube sheet 7, and the distance of tube bank and tube bank should be as far as possible little, with the compactedness of increase equipment.
Two adjacent tube banks are welded on the tube sheet 7 with pipe nipple 3.Pipe nipple 3 is connected with 180 ° of elbows 6 with pipe flange 5 successively by reducer pipe 4, and two adjacent tube banks constitute a path.As shown in Figure 2, be connected in a manner described with another tube bank, form second path, by that analogy at an end of restraining.
Cleaner fluid enters from shell side, forms turbulent flow under the effect of deflection plate, with the abundant heat exchange of tube side fluid.Contain solid particle, easy fouling or gluey easily stifled medium and enter tube bank, flow through elbow at the terminal reducing of tube bank and enter next one tube bank, finally discharge from the tube side outlet from tube side.When needs clean tube side, take the flushing of flange 5 usefulness clear water apart and get final product.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
