Abstract
A kind of waste heat boiler component is the utility model is related to, specifically installed in the economizer of waste heat boiler afterbody.It includes framework, is characterized in having between the upper side frame and lower frame of the framework in the serpentine coil continuously arranged, serpentine coil is in vertical, and its tube head and pipe tail both pass through the upper side frame of framework and be connected with header.The manufacturing cost of the economizer is relatively low, is not in drainage.
Description
Technical field
A kind of waste heat boiler component is the utility model is related to, it is special specifically installed in the economizer of waste heat boiler afterbody
Shi Yongyu not horizontal rubbish waste heat boiler.
Background technology
Economizer is that one kind is arranged on waste heat boiler afterbody, for recovery waste heat, so as to reduce the equipment of Coal-fired capacity.
The economizer installed in traditional waste heat boiler includes framework, is evenly equipped between the upper side frame and lower frame of framework perpendicular
Manage, there is upper tubulose header on the upper side frame of framework, there is lower tubulose header, the upper and lower part point of vertical tube above the lower frame of framework
Import not with upper tubulose header and lower tubulose header welds together.Vertical tube is more in this economizer, during manufacture, pad
More, the workload of welding is big, and the manpower of consumption is more so that manufacturing cost is higher.Moreover, the bottom of vertical tube and lower tubulose header
Weld easily occur the problem of leak in use.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of economizer, and the manufacturing cost of the economizer is relatively low, no
Drainage occurs.
To solve the above problems, provide following technical scheme：
Economizer of the present utility model includes framework, is characterized in having between the upper side frame and lower frame of the framework in continuous
The serpentine coil of arrangement, serpentine coil is in vertical, and its tube head and pipe tail both pass through the upper side frame of framework and be connected with collection
Case.
Wherein, the top of the serpentine coil is suspended on the upper side frame of framework by pipe clamp, and the bottom of serpentine coil leads to
Cross comb plate, comb joint to be connected so that pitch is uniform between the pipe row of serpentine coil.
The serpentine coil has multiple, and they are in same vertical plane in being arranged side by side.
Above scheme is taken, there is advantages below：
Due to having between the upper side frame and lower frame of economizer of the present utility model in the serpentine coil continuously arranged, snakelike disk
Pipe is in vertical, and its tube head and pipe tail both pass through the upper side frame of framework and be connected with header.Economizer of the present utility model
Compared with prior art, more vertical tubes are replaced using serpentine coil, only need to welds header in the tube head and pipe tail of serpentine coil, from
And the quantity of pad is greatly reduced, reduce the consumption of manpower, reduce manufacturing cost.Moreover, the tube head of serpentine coil
With pipe tail upward, top is respectively positioned on the weld of header, is leaked in use at lower weld so as to avoid
The phenomenon of water.
Brief description of the drawings
Fig. 1 is a kind of structural representation of economizer of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, economizer of the present utility model includes framework 1.Set between the upper side frame and lower frame of the framework 1
Have in the serpentine coil 3 continuously arranged, serpentine coil 3 is in vertical, and its tube head and pipe tail both pass through the upper side frame of framework 1
And it is connected with header 2.The top of the serpentine coil 3 is suspended on by pipe clamp 4 on the upper side frame of framework 1, under serpentine coil 3
Portion is connected by comb plate, comb joint 5 so that pitch is uniform between the pipe row of serpentine coil 3.The serpentine coil 3 has multiple, and they are same
It is in be arranged side by side in one vertical plane.
In use, economizer is installed to waste heat boiler afterbody.When waste heat boiler works, its flue gas discharged from afterbody,
When by the serpentine coil 3 of economizer, part heat absorption in flue gas is recycled by serpentine coil 3, it is remaining so as to reduce
The exhaust gas temperature of heat boiler, reduce the use of coal amount, reach province's coal effect.
