Abstract
The utility model relates to a shell and tube heat exchanger provided with a swirler, which consists of a tank body and a heat exchange tube, and is characterized in that the tank body takes on the shape of a horizontal cylinder, and one end of the tank body is provided with a tube box; the tank body is internally provided with a U-shaped heat exchange tube bank, a heating medium inlet end and a heating medium outlet end of which extend into two sides of a clapboard in the tube box; the upper part of the tube box is provided with a heating medium inlet tube section; the swirler is arranged at the position where the heating medium inlet tube section is connected with the tube box; the swirler comprises a round small tube and a blade arranged on the outer wall of the small tube; and the round small tube is sheathed on a cyclone bracket which is fixed on the inner wall of the tube box. The shell and tube heat exchanger has the advantages that heating medium which enters the tube box flows through the swirler, flows in a vortex way and then enters heat exchange tubes of the heat exchange tube bank in a way of rotational flow for powerfully flushing the inner walls of the heat exchange tubes, so that the fouling on the surface of the inner walls of the tubes can be reduced, and the heat transfer efficiency of the heat exchanger is improved. The shell and tube heat exchanger can be used as the heating medium for urban domestic sewage, industrial waste water and viscous oil waste liquid, has better cleaning effect for flushing the inner walls of the tubes, and is applicable to the shell and tube heat exchanger which is provided with the swirler and has multiple heating mediums.
Description
Technical field
The utility model belongs to the not direct heat-exchange device of contact of heat exchange medium, particularly a kind of shell and tube exchanger that can accelerating medium flows with swirl-flow devices.
Background technology
Shell and tube exchanger is widely used in air-conditioning, chemical industry, biology, field of food, shell and tube exchanger is to be arranged in the circle tube tank body by one group of heat-exchanging tube bundle that is arranged in parallel to constitute, heating agent flows in heat-exchanging tube bundle, rely on that the heat exchange tube wall surface is long-pending gives heated medium in the circle tube tank body with exchange heat, so form exchange heat.Existing shell and tube exchanger, because the heat-exchanging tube bundle limited length, the heat exchange tube wall area is just limited, heat exchange efficiency just is restricted.For the bigger shell and tube exchanger of heat exchange amount, strengthen heat exchange tank volume in order to increase the heat exchange amount, will increase manufacturing cost, this is uneconomical suitable.Need simple in structurely, novel, the shell and tube exchanger of practicality and high efficiency is to satisfy needs of society.
Summary of the invention
The purpose of this utility model is, design and produce a kind of shell and tube exchanger with cyclone, heat-exchanging tube bundle heating agent import department at shell and tube exchanger is provided with cyclone, utilize the rotation of the impact flow cyclone of heating agent, the rotation of cyclone can be quickened the flowing velocity of heating agent, thereby improves the heat exchange efficiency to heated medium.
The technical solution of the utility model is following realization, a kind of shell and tube exchanger with cyclone, form by tank body and heat exchanger tube, tank body is horizontal cylindrical shape, tank body top is provided with the heated medium outlet pipe section, the tank body bottom is provided with heated medium import pipeline section, tank body one end is provided with bobbin carriage, be provided with the U type heat-exchanging tube bundle of marshalling in the tank body, the heating agent entrance point and the heating agent port of export of U type heat-exchanging tube bundle put in the bobbin carriage, between the heating agent entrance point of the U type heat-exchanging tube bundle in bobbin carriage and the heating agent port of export dividing plate are set, and bobbin carriage top is provided with heating agent import pipeline section, the bobbin carriage bottom is provided with the heating agent outlet pipe section, and the place is provided with cyclone at heating agent import pipeline section tube connector case.
Aforesaid cyclone is made of the blade of circular tubule and the setting of tubule outer wall, and circular tubule is sleeved on the eddy flow support, and the eddy flow support is fixed on the bobbin carriage inwall.
Major advantage of the present utility model is: the heating agent that enters bobbin carriage is flowed through behind the cyclone, become eddy current to flow, eddy flow enters each heat exchanger tube of heat-exchanging tube bundle again, be the eddy flow state owing to enter the heating agent of heat exchanger tube, the heat exchanging inside pipe wall has powerful scouring force, inside pipe wall surface dirt is reduced, improve the heat transfer coefficient value of heat exchanger.Because the inside pipe wall dirt is rotated current and washes out, and be pulled away with flow and drain into outside the heat exchanger, thereby reduced obstruction in the dirt exchange heat pipe.Can reduce heat exchanger maintenance load at ordinary times, reduce the maintenance cost spending.To city domestic sewage and industrial assorted waste water, thickness oils waste liquid uses as heating agent, and is better to its inside pipe wall dirt and greasy dirt flush clean effect.
The utility model is applicable to the shell and tube exchanger of the band cyclone of multiple heating agent.

The specific embodiment
As seen from Figure 1, a kind of shell and tube exchanger with cyclone, form by tank body and heat exchanger tube, tank body 1 is horizontal cylindrical shape, tank body top is provided with heated medium outlet pipe section 2, the tank body bottom is provided with heated medium import pipeline section 3, tank body one end is provided with bobbin carriage 4, be provided with the U type heat-exchanging tube bundle 5 of marshalling in the tank body, the heating agent entrance point and the heating agent port of export of U type heat-exchanging tube bundle put in the bobbin carriage, between the heating agent entrance point of the U type heat-exchanging tube bundle in bobbin carriage and the heating agent port of export dividing plate 6 are set, and bobbin carriage top is provided with heating agent import pipeline section 7, the bobbin carriage bottom is provided with heating agent outlet pipe section 8, and the place is provided with cyclone 9 at heating agent import pipeline section tube connector case.
By Fig. 2,3 as seen, cyclone is made of the blade 12 of circular tubule 11 and the setting of tubule outer wall, and circular tubule is sleeved on the eddy flow support 13, and the eddy flow support is fixed on bobbin carriage 4 walls.
Its course of work is as follows: heating agent can be a hot water, or deep fat, or municipal sewage, or industrial assorted waste water, thickness oils waste liquid, heating agent enters bobbin carriage and flows through behind the cyclone, becomes eddy current to flow, and eddy flow enters each heat exchanger tube of heat-exchanging tube bundle again, the heat of heating agent exchanges to the heated medium in the tank body (as cold water) by the heat exchanger tube tube wall, after cold water is heated, from the heated medium outlet pipe section outflow on tank body top, for using.Heating agent flows in heat exchanger tube, to its inside pipe wall dirt and greasy dirt flush clean, reduces heat exchanger maintenance load at ordinary times, reduces the maintenance cost spending.
