Abstract
The utility model discloses a kind of section round return combustion chambers with drum arranged concentric, including cut round front tube sheet, cut circle back tube sheet, arc shell ring and top plate；It cuts on round front tube sheet and is provided with flue connecting hole and smoke pipe connecting hole, flue connecting hole, which is located at, cuts round front tube sheet lower part, and smoke pipe connecting hole is distributed in around flue connecting hole；It cuts round front tube sheet and cuts a round back tube sheet edge and be provided with and pull side, arc shell ring both ends are welded on the pulling on side of front and back tube sheet, and top plate is welded on the arc shell ring top.Using the return combustion chamber of the structure, can effectively solve due to limited by return combustion chamber and caused by drum diameter is bigger than normal, water capacity is big and the technical problem of load responding time length.
Description
Technical field
The utility model is related to a kind of boiler return combustion chambers, and in particular to a kind of circle of cutting with drum arranged concentric is strile-backd
Room.
Background technology
It is provided in boiler national standard, manufactured boiler, it must there are certain steam between return combustion chamber and drum
Space.In order to meet this regulation, often by return combustion chamber and drum eccentric setting, design so not only can make drum straight for manufacturer
Diameter increases, and increases manufacturing cost and floor space, and a large amount of idle spaces can be had more between drum and return combustion chamber, so as to cause
Water capacity increases, and the load responding time is long, is unfavorable for industrial production.
Utility model content
For the above-mentioned existing prior art, the utility model to solve due to limited by return combustion chamber and caused by drum diameter
Bigger than normal, water capacity is big and the technical problem of load responding time length.
In order to achieve the above object, technical solution used by the utility model is：A kind of and drum arranged concentric is provided
Cut round return combustion chamber, including cut round front tube sheet, cut round back tube sheet, arc shell ring and top plate；It cuts on round front tube sheet and sets
It is equipped with flue connecting hole and smoke pipe connecting hole, flue connecting hole, which is located at, cuts round front tube sheet lower part, and smoke pipe connecting hole is distributed in stove
Around courage connecting hole；It cuts round front tube sheet and a section round back tube sheet edge is provided with and pulls side, arc shell ring both ends are welded on front and back
Tube sheet is pulled on side, and top plate is welded at the top of arc shell ring.
The utility model has the beneficial effects that：Return combustion chamber is by cutting round front tube sheet, cutting round back tube sheet, arc shell ring and cylinder
Body forms, simple in structure, easy to produce, and cuts circular return combustion chamber and can substantially to reduce drum after drum arranged concentric straight
Diameter not only reduces floor space, but also reduces manufacturing cost.It cuts on round front tube sheet and is provided with flue connecting hole and smoke pipe connecting hole,
Easily return combustion chamber can be connected to flue and smoke pipe, after which is installed to drum inside, pot can be improved
Cylinder inner space utilization rate, reduces water capacity, so as to shorten the load responding time, improves production efficiency.Cut round front tube sheet and
It cuts round back tube sheet edge and is provided with and pull side, due to pulling the presence on side, the bonding area between arc shell ring and tube sheet increases, weldering
It is more convenient when connecing, after welding more securely.
Based on the above technical solution, the utility model can also do following improvement.
Further, it is flat tube sheet to cut round front tube sheet and cut round back tube sheet.
Advantageous effect using above-mentioned further technical solution is：Tube sheet is flat tube sheet, manufacturing process letter before and after return combustion chamber
It is single, and flat tube sheet connect with other component it is more secured.
Further, it cuts round back tube sheet and is provided with maintenance cylinder connecting hole.
Advantageous effect using above-mentioned further technical solution is：Maintenance cylinder connecting hole, connection inspection are provided on back tube sheet
After repairing cylinder, service personnel can enter return combustion chamber by overhauling cylinder, be safeguarded to return combustion chamber, maintenance and repair are more convenient.
Description of the drawings
Fig. 1 is the front view of the utility model；
Fig. 2 is the rearview of the utility model；
Fig. 3 is the vertical view of the utility model；
Wherein, 1, top plate；2, arc shell ring；3, smoke pipe connecting hole；4, flue connecting hole；5, cylinder connecting hole is overhauled；6, it cuts
Round front tube sheet；7, round back tube sheet is cut；8, side is pulled.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In the embodiments of the present invention, as shown in Figures 1 to 3, a kind of section circle time with drum arranged concentric is provided
Room is fired, including cuts round front tube sheet 6, cut round back tube sheet 7, arc shell ring 2 and top plate 1.After cutting round front tube sheet 6 and cutting circle
Tube sheet 7 can be convex tube sheet or flat tube sheet, in the present invention, more firm in order to make return combustion chamber connect with other component
Gu and reduce manufacture difficulty, tube sheet preferentially uses flat tube sheet before and after return combustion chamber.In order to reduce welding difficulty and welding after more
Add securely, side 8 is pulled cutting round front tube sheet 6 and cutting 7 edge of round back tube sheet to be provided with.When welding, 2 both ends of arc shell ring difference
It is welded on and cuts round front tube sheet 6 and cut the pulling on side 7 of round back tube sheet 7.It is provided with flue connecting hole on cutting round front tube sheet 6
4 and smoke pipe connecting hole 3, flue connecting hole 3, which is located at, cuts 6 lower part of round front tube sheet, and smoke pipe connecting hole 3 is distributed in flue connecting hole 4
Around, after which is installed to drum inside, drum inner space utilization rate can be improved, reduces water capacity, to contract
The short load responding time improves production efficiency.It is provided with maintenance cylinder connecting hole 5 on cutting round back tube sheet 7, overhauls cylinder connecting hole
5 are located at section 6 middle part of round back tube sheet.After overhauling 5 connection maintenance cylinder of cylinder connecting hole, situation in return combustion chamber can be observed at any time, is occurred
When failure, opens manhole and overhauled, it is easy to operate.
Although being described in detail to specific embodiment of the present utility model in conjunction with attached drawing, should not be construed as pair
The restriction of the protection domain of this patent.In range described by claims, those skilled in the art are without creative labor
The dynamic various modifications that can be made and deformation still belong to the protection domain of this patent.
