Description
Technical field
The present invention relates to a kind of heater, particularly using steam as the pipeline vapour-liquid hybrid heater of heat source.
Background technology
Vapor-liquid mixer is a kind of novel steam direct heater, is divided into series flow pipeline vapor-liquid mixer and submergence
Two kinds of formula steam heater, is widely used in heating system in heating, air-conditioning.Mainly utilize steam heater convection current serial ports pipeline
Realize that steam is passed through with liquid bidirectional, directly liquid (such as water) heated so as to fulfill steam that there is thermal efficiency height, installation
Simply, the advantages of not taking up space, tranquil cold (liquid) water being heated to boiling point, but also there is a small amount of noise and vibration etc. to lack
Point.
Existing common pipeline vapour-liquid hybrid heater is made of core pipe (Rafael nozzle) and shell, and core pipe wall has very much
Inclined hole, the comparatively small position of core pipe water inlet end are aditus laryngis, and core pipe middle section is Hybrid Heating area, are to steam between core pipe and shell
Vapour area.In the duct type course of work, cold liquid sprays at a high speed heating zone from aditus laryngis, meanwhile, steam sprays at a high speed from core pipe inclined hole
Heating zone, vapour-liquid mixed heat transfer produce the liquid of high temperature.
The tube wall of this structural requirement core pipe first is thicker, could drill out again with the oblique of angle of inclination in core pipe
Hole is just conducive to steam and smoothly enters in liquid.How much the number of openings can directly affect the efficiency of vapour-liquid contact, in order to open more
More holes usually just needs to expand core pipe overall dimensions as far as possible.The core pipe of heavy wall, not only consuming material is more, to processing also band
Carry out difficulty of processing, the demand occasion of some small dimensions is difficult to process suitable core pipe.Core pipe is tapered, is opened above
Inclined hole with angle of inclination is also less susceptible to operate.So this usual volume of type of conduits vapour-liquid hybrid heater is bigger, consumption
Material is more, there is certain difficulty of processing, so cost is also higher.
Invention content
In view of this, the present invention provides a kind of novel pipeline vapour-liquid hybrid heater.New pipeline vapour-liquid hybrid heater
There is volume smaller, the characteristics of difficulty of processing is low, and vapour-liquid contact area is efficient greatly.The core pipe of novel pipeline vapour-liquid hybrid heater
It is by being formed by stacking after special processing using multiple concentric reduced pipes (casing), there are gaps or logical between each casing
Road.Then entire core pipe is packed into a display pipe.The core Bottomhole pressure that cold liquid is formed in casing, the reducing structure of casing
Can direction flowing be reduced along casing diameter variable with conducting fluid, the structure of the concentric reducing of casing can ensure that cold liquid is flowing over
Reflux is not generated in journey.Hot steam is entered by display pipe around core pipe, under the action of steam pressure, steam along casing it
Between gap or channel, along casing diameter variable reduce direction enter inside core pipe, contact mixing with the cold liquid inside core pipe.
Specific scheme of the invention is as follows：
A kind of novel pipeline vapour-liquid hybrid heater, including shell, core pipe, the core pipe by least two it is concentric different
Diameter pipe superposing type is formed by connecting；The connection mode of two adjacent Concentric Reducers is：It is small by a Concentric Reducers bore
One end is nested into the big one end of another Concentric Reducers bore, and connection is fixed, and junction has inside and outside connection core pipe
Gap.
Preferably, each Concentric Reducers of composition core pipe are identical structure.
Further, the connection mode of Concentric Reducers is：It is connected together between two adjacent Concentric Reducers；With one heart
Reduced pipe has following three kinds of structures:
The first structure：The Concentric Reducers are bullet, and there are two horizontal strokes of different sizes for the bullet
Section, small cross section is inscribed within big cross section, and at least there are two point of contacts for tool.
Second of structure：The Concentric Reducers, structure are：Bullet is combined with plaited skirt shape body integral type；It is close
The small one end of bore is bullet, is plaited skirt shape body close to the big one end of bore；There are a cross sections on bullet to be inscribed within
The cross section in plaited skirt shape body somewhere, and at least there are two point of contacts for tool.
The third structure：The Concentric Reducers, structure are：Bullet is combined with prismoid integral type；Close to mouth
The small one end of diameter is bullet, is prismoid close to the big one end of bore；There are a cross sections on bullet to be inscribed within terrace with edge
The cross section in body somewhere, and at least there are two point of contacts for tool.
Other than being connected together, the another connection mode of Concentric Reducers can be welding：Adjacent two are with one heart
Connection between reduced pipe is spot welding, has spacing between solder joint, and the solder joint is located at the inner surface and quilt cover for being inserted in end
Between the outer surface at end, make to be inserted in the inner surface at end with the outer surface at quilt cover end with certain gap.
Compared with prior art, the beneficial effects of the present invention are：This way processing is simple, and core component is processing group
Part is concentric reduced pipe, has highly developed universal process equipment, relatively thin material may be used, difficulty of processing is small.Core pipe
Assembling mode it is also simple, it is only necessary to superposition is fixed.

Specific embodiment
For those skilled in the art, can other various phases be obtained according to disclosed structure and principle
The change and deformation answered, and all these change and deformation belongs to protection category of the invention.
A kind of novel pipeline vapour-liquid hybrid heater, including shell 1, core pipe 2, the core pipe 2 by least two it is same
Heart reduced pipe superposing type is formed by connecting；The connection mode of two adjacent Concentric Reducers is：By a Concentric Reducers bore
Small one end is nested into the big one end of another Concentric Reducers bore, and connection is fixed, and junction has connection core pipe 2
Inside and outside gap.
Preferably, each Concentric Reducers of composition core pipe 2 are identical structure.
As advanced optimizing for said program, the connection mode of Concentric Reducers is：Two adjacent Concentric Reducers
Between be connected together；There are following three kinds of connection schemes:
Scheme 1：
