Description
Technical field
This utility model relates to technical field of heat exchangers, particularly to a kind of two-tube-pass heat exchanger.
Background technology
Heat exchanger is the equipment that the partial heat of hot fluid passes to cold flow body.Exchange capability of heat is by heat exchanging fluid character, heat exchange stream
The factors such as body temperature is poor, the geometry of the flow velocity of fluid, heat-transfer surface determine.Heat exchanging fluid character is fluid self-characteristic,
Being difficult to change, meanwhile, heat transfer temperature difference is heat exchanging fluid technical conditions under specific operation, it is also difficult to change.Therefore, improve
Exchange capability of heat, needs geometrically suitably changing at heat transmission equipment with on rate of flow of fluid.In normal work, due to pipe
The circulation area of the shell-side fluid of shell heat exchanger is relatively big, and flow velocity is difficult to improve, and constrains exchange capability of heat and improves；Plate type heat exchanger
Circulation crack limited width, liquid exponentially changes at the spatial flow of 1mm～3mm, resistance, consumes additionaling power relatively big,
Economy is far inferior to Bottomhole pressure, and flow velocity and the coefficient of heat transfer present index variation.Currently, wide-runner plate heat exchanger is applied,
Heat exchange film layer thickens, and is unfavorable for improving heat exchange efficiency；Especially for the heat exchange of sewage, the reduction of flow rate of liquid, it is unfavorable for removing
Dirt.
Summary of the invention
In order to solve problem of the prior art, this utility model provides a kind of two-tube-pass heat exchanger energy-conservation, efficient.
Technical scheme described in the utility model is as follows:
A kind of two-tube-pass heat exchanger, including condensation chamber, connects evaporation cavity by rise and fall pipe below described condensation chamber, described
Evaporation cavity, condensation chamber and rise and fall pipe between cavity formed one close condition of high vacuum degree cavity, described closing fine vacuum
Fill low boiling working media in degree cavity, coolant tube bank is installed in described condensation chamber, in described evaporation cavity, heat is installed
Matchmaker restrains.
Described coolant tube bank and heating agent tube bank are for straight tube bundle in the heat exchange for sewage, it is possible to realize backwash, improve and set
Standby service life.
When a kind of two-tube-pass heat exchanger uses, series connection can be organized more, improve heat transfer temperature difference, it is also possible to carry out organizing parallel connection more, come
Adapt to big flow heat-exchange system, under many group series connection or many groups operating mode in parallel, can the cavity of the most re-closed condition of high vacuum degree
Inside fill different low boiling working medias.
The technical scheme that this utility model provides has the benefit that
Flowing in tube side by the coolant of heat exchanging fluid and heating agent all being designed, cold and hot bundle profile becomes cavity, is pumped in cavity
A certain degree of vacuum, and fill low boiling working media, and segmentation can be realized, it is effectively improved heat transfer temperature difference.Carry at circulating resistance
Under high limited premise, it is effectively improved flow velocity, and heat transfer temperature difference is improved so that the coefficient of heat transfer is improved, and heat exchange area subtracts
Little, weight of equipment reduces, and cost reduces.
Forming the conductor of the thermal resistance that goes to zero in closing condition of high vacuum degree cavity, low thermal resistance heat exchange makes heat exchange loss reduce.Flow velocity
It is effectively increased, increases substantially the coefficient of heat transfer so that the coefficient of heat transfer is than the increase by 3 of shell-and-tube heat exchanger～5 times, but has more one
Tube wall heat transfer process, Comprehensive Correlation, in conjunction with actual measurement data, complete the equipment of identical heat exchange amount, weight is only shell-and-tube
The 35～66% of heat exchanger.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, required use in embodiment being described below
Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only embodiments more of the present utility model, right
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is implemented
Mode is described in further detail.
As it is shown in figure 1, a kind of two-tube-pass heat exchanger, including condensation chamber 2, by rise and fall pipe 1 below described condensation chamber 2
Connection evaporation cavity 4, the cavity between described evaporation cavity 4, condensation chamber 2 and rise and fall pipe 1 forms one and closes condition of high vacuum degree
Cavity, fill low boiling working media in described closing condition of high vacuum degree cavity, in described condensation chamber 2, be provided with coolant tube bank 3,
Heating agent tube bank 5 it is provided with in described evaporation cavity 4.
It is for straight tube bundle in the heat exchange for sewage that described coolant tube bank 3 and heating agent restrain 5, it is possible to realizes backwash, carries
The service life of high equipment.
When a kind of two-tube-pass heat exchanger uses, series connection can be organized more, improve heat transfer temperature difference, it is also possible to carry out organizing parallel connection more, come
Adapt to big flow heat-exchange system, under many group series connection or many groups operating mode in parallel, can the cavity of the most re-closed condition of high vacuum degree
Inside fill different low boiling working medias.
During work, heating agent fluid (water) enters heating agent tube bank 5, and heating agent fluid is in flow process, and heating agent restrains the tube wall of 5
Temperature improves so that after the low boiling working media in evaporation cavity 4 becomes High Temperature High Pressure gas-liquid mixture, enters condensation chamber 2,
In condensation chamber 2, High Temperature High Pressure gas-liquid mixture is in the outer wall condensation heat release of coolant tube bank 3, by coolant tube bank 3 to coolant
In tube bank 3, coolant fluid heats.When evaporation cavity 4 is equal with gas-liquid mixture temperature in condensation chamber 2, it is achieved heat passes
Go to zero during passing thermal resistance.Coolant fluid and heating agent fluid are respectively in coolant tube bank 2 and heating agent tube bank 4, and cold fluid and hot fluid mixes
The probability closed reduces, and is conducive to the heat exchange of dangerous fluid.Coolant fluid and heating agent fluid are restrainted and heat medium pipe at refrigerant pipe 3 respectively
In bundle 4, owing to single tube diameter is less, bearing capacity is strong, can be used for the heat exchange of relatively high pressure liquid.Single group device can be to cold and hot
The flow of fluid is designed so that device is easy to standardized production, beneficially the series connection of equipment and used in parallel.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all of the present utility model
Within spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in protection domain of the present utility model
Within.
