Technical scheme be explicitly described, it is clear that described embodiment is invention part of the embodiment, rather than whole realities
Apply example.Based on the embodiment in invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belong to the scope of invention protection.
In the description of the invention, unless otherwise indicated, the orientation of the instruction such as term "left", "right" or position relationship are base
In orientation shown in the drawings or position relationship, description description of the invention and simplified, rather than instruction or hint are for only for ease of
Signified system or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this
The limitation of invention.
It should be noted that unless otherwise clearly defined and limited, term " connection " should be interpreted broadly, for example, can
To be to be fixedly connected or be detachably connected, or it is integrally connected；Can be joined directly together, middle matchmaker can also be passed through
Jie is indirectly connected.For the ordinary skill in the art, tool of the above-mentioned term in invention can be understood with concrete condition
Body implication.
As depicted in figs. 1 and 2, the invention provides a kind of heat-exchanger rig for variable working condition, the device to include the He of housing 1
Two bobbin carriages 2, the both ends of housing 1 are connected by tube sheet 3 with corresponding bobbin carriage 2 respectively, and the device also includes first partition 5 and second
Dividing plate, first partition 5 along housing 1 it is axially extending be arranged in housing 1, it is multiple so that the inner space of housing 1 to be separated into
Shell side space 1-1, second partition are arranged in bobbin carriage 2, so that the inner space of bobbin carriage 2 to be separated along the axially extending of bobbin carriage 2
Into with the one-to-one tube side spaces of shell side space 1-1, be equipped with heat exchanger tube 4 in each shell side space 1-1, the two of heat exchanger tube 4
End is connected by tube sheet 3 with corresponding tube side space respectively, and the outer wall of housing 1 is provided with one-to-one with shell side space 1-1
First tube assembly, the first tube assembly include the first inlet tube 6-1 and the first outlet connected respectively with shell side space 1-1 both ends
Pipe 6-2, the outer wall of bobbin carriage 2 is provided with to be included respectively with two with one-to-one second tube assembly in tube side space, the second tube assembly
The the second inlet tube 7-1 and second outlet pipe 7-2 of the corresponding shell side space 1-1 connections of individual bobbin carriage 2, the first all inlet tubes
Valve is equipped with 6-1, first outlet pipe 6-2, the second inlet tube 7-1 and second outlet pipe 7-2.
In use, gas to be heated can be passed through into the first inlet tube 6-1, be passed through into the second inlet tube 7-1 treat it is cold
But liquid.When the plant running is in off-design behaviour, for example, when gas to be heated is less：Can be according to real gas
Flow is only passed through hot gas to be added to part shell side space 1-1, i.e., only opens the first import connected with part shell side space 1-1
Valve on pipe 6-1 and first outlet pipe 6-2；At the same time, lead to only into the tube side space connected with these shell side spaces 1-1
Enter liquid to be cooled, that is to say, that only open the second inlet tube 7-1 and second outlet pipe 7-2 connected with these tube side spaces
On valve.Thus, liquid to be cooled can pass sequentially through the second inlet tube 7-1 and tube side space flows into and is arranged on shell side space
In heat exchanger tube 4 in 1-1, due to being filled with the hot gas to be added flowed into by the first inlet tube 6-1 in the 1-1 of shell side space, because
This hot gas to be added can constantly absorb the heat of liquid to be cooled by heat exchanger tube 4, until flowed out from first outlet pipe 6-2, with
This simultaneously, liquid to be cooled also constantly can discharge heat to hot gas to be added, until passing sequentially through outlet with heat exchanger tube 4
Tube side space and second outlet pipe 7-2 outflow.
When gas flow to be heated increases：It can will be always maintained at closing before according to the increase degree of gas flow
Part or all of first inlet tube 6-1 and first pipe 6-2 on valve open so that the gas increased can by these the
One inlet tube 6-1 flows into the shell side space 1-1 communicated therewith, at the same time, empty to the tube side connected with these shell side spaces 1-1
Between be passed through liquid to be cooled, that is, open the valve on the second inlet tube 7-1 and second outlet pipe 7-2 connected with these tube side spaces
Door.
When gas flow to be heated reduces：The inlet tube of part first can be closed according to the reduction degree of gas flow
Valve on 6-1 and first outlet pipe 6-2, it is same with this to increase the flow velocity of hot gas to be added in the first inlet tube 6-1 of residue
When, the valve closed on the second inlet tube 7-1 and second outlet pipe 7-2 that are connected with corresponding tube side space.
Housing 1 is separated into multiple shell side space 1-1 by the present invention by using first partition 5, by using second partition
Bobbin carriage 2 is separated into multiple tube side spaces so that when actual condition changes, only need to by control the keying of each valve come
Adjust the shell side space 1-1 of actual participation heat exchange and the quantity in tube side space, so that it may actual heat exchange area is become with actual condition
Change and change, and the flow velocity that also avoid at the first inlet tube 6-1 and the second inlet tube 7-1 varies widely, so as to not
The stability of the heat transfer effect and first outlet pipe 6-2 and second outlet pipe 7-2 outlet temperature under variable working condition is only ensure that,
But also greatly reduce floor space.
Further, the quantity of first partition 5 is multiple that each first partition 5 is arranged in a crossed manner.For example, work as first partition 5
Quantity when being two, two first partitions 5 are arranged in a crossed manner, i.e. two first partitions 5 intersect to form cross section to be criss-cross
Structure.
It should be noted that multiple first partitions 5 are except can be in addition to arranged in a crossed manner, can also to be arranged in parallel.Such as Fig. 3 institutes
Show, the quantity of first partition 5 is multiple, radial direction interval of multiple first partitions 5 along housing 1 and is be arranged in parallel.
Preferably, first partition 5 is provided with least one passage, to balance the pressure in each tube side space 1-1.Separately
Outside, because the aperture of passage is smaller, therefore more hot gas to be added will not be caused to leak into adjacent tube side space 1-1.
Further, the import of the first all inlet tube 6-1 and all first outlet pipe 6-2 outlet pass through respectively
Valve connects with air supply pipe 8 and muffler 9, all the second inlet tube 7-1 import and going out for all second outlet pipe 7-2
Mouth is connected by valve with feed pipe 10 and liquid back pipe 11 respectively.
In addition, also including controller, all valves are the magnetic valve being electrically connected with the controller.
Finally it should be noted that：Above example is only to illustrate the technical scheme of invention, rather than its limitations；Although ginseng
Invention is described in detail according to previous embodiment, it will be understood by those within the art that：It still can be right
Technical scheme described in foregoing embodiments is modified, or carries out equivalent substitution to which part technical characteristic；And this
A little modifications are replaced, and the essence of appropriate technical solution is departed from the spirit and scope for inventing each embodiment technical scheme.
