Specific embodiment
To better understand the objects, features and advantages of the present invention, with reference to the accompanying drawings and examples
The present invention will be further described.It should be noted that in the absence of conflict, in embodiments herein and embodiment
Feature can be combined with each other.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other modes described herein are different from, therefore, the present invention is not limited to the specific of specification is described below
The limitation of embodiment.
Embodiment 1, as shown in Figure 1 and Figure 2, the present invention provides a kind of flue gas waste heat recoveries detachably to spray dust-collecting and heat exchanging
Device, for the heat exchanger, it is not difficult to find out that, there are two function and an architectural characteristic, two functions are respectively from title,
Flue gas waste heat recovery, i.e. the essence work of heat exchanger, the other is dedusting, i.e. dust in removing flue gas, an architectural characteristic
It is then whole is all that can dismantle setting, for above-mentioned feature, specifically specific design of the invention once.
It includes Cylinder Shell that flue gas waste heat recovery, which detachably sprays dust-removing heat exchanger, whole for Cylinder Shell
Body is the design scheme of tubular type, be integrally it is demountable, if be finely divided, Cylinder Shell if includes three
Point, that is, the flue gas for including central enclosure, the flue gas inlet tube of central enclosure lower part being set and central enclosure top is set
Outlet, between flue gas inlet tube, smoke outlet tube and central enclosure be using ring flange and be bolted it is fixed, it is right
For the connection of three, and have and require accordingly, that is, the airtightness of three, inventor is in the position connected two-by-two
It sets, is provided with anti-gas-leak gasket；Other than the design of Cylinder Shell, inventor in order to realize essential function of the invention,
It is provided with two critical components inside Cylinder Shell, is heat-exchanger rig and spray assemblies respectively, for heat-exchanger rig and spray
The setting position for drenching component is also to require, and heat-exchanger rig is then the center position that Cylinder Shell is arranged in, and is also
It is bolted on the inside of Cylinder Shell, equally when bolt is fixed, and needs anti-gas-leak gasket, only not
It crosses the gas leakage gasket of putting being arranged here and belongs to small-sized, for spray assemblies, the major part of its own is to be in cylindrical type
Enclosure interior, fixed form here is not bolted between spray assemblies and Cylinder Shell, so for leakage
The problem of gas, does not have to then too consider.
Below specifically once, the specific setting of heat-exchanger rig and spray assemblies.
As depicted in figs. 1 and 2, heat-exchanger rig includes that the heat exchanger tube being arranged on the inside of Cylinder Shell maintains frame, here
Heat exchanger tube maintain frame be then heat-exchanger rig main bracing frame, it can be seen from the figure that its heat exchanger tube maintain frame in central tube
There is a setting in the upper and lower part of body, purpose be also it is the same, it is then to be bolted on middle part shell that heat exchanger tube, which maintains frame,
Internal side, heat exchanger tube maintains the middle part of frame to be provided with mandrel, and for mandrel, the main purpose of setting is then center
The effect that main body is fixedly connected；The outside of its mandrel is provided with spiral heat exchange tube, it is not difficult to find out that, spiral heat exchange tube is then from figure
Be fixed on heat exchanger tube maintain frame on, why by heat exchange tube design at the shape of spiral, purpose is changed also for longer
The contact duration and heating surface area of hot liquid, in order to enable spiral heat exchange tube to be connected to external, inventor is on the top of mandrel
It is provided with mounting flange component with lower part, Cong Tuzhong is it can also be seen that if for the intermediate cross-section of Cylinder Shell
Words, heat-exchanger rig are the designs of a symmetrical structure, mounting flange component then include with the ring flange of mandrel fixed setting,
The fixed disk that is equipped with ring flange and the refrigerant runner pipe that setting is connect with fixed disk, the design for ring flange are also
Relatively good understanding, so not being described in detail, fixed disk is then other than the fixed part of its own, and upper part is also
There is semicircular cavity, purpose is designed also for multiple spiral heat exchange tubes, for refrigerant runner pipe, comes to two
A, structure is the same, but acts on difference, and according to effect, inventor, which split into, to be arranged on central enclosure top
Refrigerant inlet pipe and the refrigerant exit pipe of central enclosure lower part is set, be also to use for ring flange and fixed disk
Bolted connection type, although do not have to here be the problem of being connected and fixed with shell, be accounted for leakage, therefore
This, is desirably also the leak-proof washer of response between ring flange and fixed disk.
The setting of its spray assemblies, purpose are then the dust in order to remove flue gas, that is, include running through Cylinder Shell one
The spray of a side is laterally responsible for, and also includes two parts for spray laterally supervisor, i.e. import tube portion and elongation pipe portion
Point, import tube portion is integrally designed with flue gas inlet tube, is extended and is used spiral shell between tube portion and import tube portion
The mode of line connection, inventor are laterally responsible for realize the effect that can be sprayed in integral tube body cavity in spray
It is upper to be provided with spray tube, it is noted here that its spray tube to maintain frame be vertically arranged with heat exchanger tube, the bottom of spray tube
Maintain frame concordant with the heat exchanger tube of lower part.
Other than above-mentioned design, inventor has also done design:
Fixed plate is provided on its refrigerant runner pipe, the purpose of fixed plate is then to realize refrigerant runner pipe and cylinder
Shell body further fixes, and is also to be arranged between fixed plate and Cylinder Shell using the connection of bolt, also needs here certainly
Want anti-gas-leak gasket；
From figure 1 it appears that the upper and lower part of spiral heat exchange tube, which passes through connecting tube, connect setting with ring flange,
The setting of connecting tube then realizes being connected to for refrigerant inlet pipe and refrigerant exit pipe；
For core shaft design, if subdivision comprising major diameter long tube and setting major diameter long tube top and under
The path short tube in portion, it is evident that its path short tube is connected and fixed with ring flange；
From figure 2 it can be seen that the two sides of its central enclosure are provided with fixed part, which is then for cooperating heat exchange
Device integral installation, so not being described in detail.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
It imitates embodiment and is applied to other fields, but without departing from the technical solutions of the present invention, according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the protection scope of technical solution of the present invention.
