Description
Technical field
The utility model is related to a kind of heat exchanger, more particularly to the cleaning integrated apparatus of a kind of pipe heat exchanger.
Background technology
Tubular type (also known as shell-and-tube, shell and tube) heat exchanger is most typical dividing wall type heat exchanger, its application industrially
There is long history, and still occupies leading position in all heat exchangers so far.Pipe heat exchanger mainly has shell, pipe
Beam, tube sheet and envelope first class sections composition, how rounded shell is, and inside is equipped with bundle of parallel tubes, and tube bank both ends are fixed on tube sheet.
The two kinds of fluids to exchange heat in pipe heat exchanger, for one kind in Bottomhole pressure, stroke is known as tube side;One kind exists
The outer flowing of pipe, stroke are known as shell side.The wall surface of tube bank is heat-transfer area.To improve extratubal fluid heat transfer coefficient, usually in shell
A certain number of lateral baffle plates are installed in vivo.Baffle plate can not only prevent fluid short, increase fluid velocity, also force
Fluid, by tube bank, makes less turbulence greatly increase by the regulation multiple cross-flow in path.Common plate washer has discount vibram outlet shape and disc
Two kinds, the former application is more extensive.Fluid is often once known as a tube side in pipe by restraining, and is often once known as by shell
One shell side.For improve tube fluid speed, appropriate partition board can be set in the end socket of both ends, by whole pipe equipartitions at
Several groups.In this way, fluid can be restrained only repeatedly by partial tube back and forth every time, referred to as multitube distance.Equally, outer to improve pipe
Flow velocity, longitudinal plate washer can be installed in shell makes fluid multipass shell space, claims muitishell, it is seen that pipe heat exchanger it is interior
Portion's structure is more complicated, and bend is more.
When pipe heat exchanger usage time is long, it is exposed at shell space inner tubal wall or shell wall and is easy to tie incrustation scale,
Influence heat transfer effect, it is therefore desirable to periodic cleaning.And chemical cleaning solution is mostly used at present in such a way that fixed-direction flows through shell side
It carries out, since the internal structure of pipe heat exchanger is more complicated, bend is more, causes edge to be easy to shelter evil people and countenance evil practices, due to corner
Direction differ, therefore chemical cleaning solution flows through shell side with fixed-direction can only clean to the corner of a part of direction, opposite court
To corner be then not easy to clean up very much.
Current also related pipe heat exchanger can realize the report of two-way cleaning, but mostly be in addition to use positive and negative driving motor
It is driven, it has not been convenient to realize integration, and water tank only has single rinse bath, need to shut down and change cleaning solution, inefficiency.
