Description
Technical field:
The utility model relates to the cylinder type cold slag machine structure, is specifically related to a kind of double-deck breeches pipe calandria structure of novel barrel slag cooler inside.
Background technology:
Barrel slag cooler adapts to fluidized-bed combustion boiler to be designed and developed to the requirement that big capacity direction develops, generally form, be used for the warm sludge cooling of fluid bed and fluidized bed boiler by unify electric control gear etc. of louvered heat transfer cylinder, slag input device, deslagging device, rotating mechanism, cooling water system.
The cold slag machine weight of domestic popular double-layer plate welding of past, pressure vessel type double-wall structure is heavier, and also there are many drawbacks in the structure of pressure vessel pattern, and its rigidity, security are all relatively poor.Although the vertical steel pipe of the usefulness that has replaces double-wall structure, but it is many that the female pipe of female pipe and backwater that supplies water is gone up the quantity of perforate welding, welding capacity is very big, the welding procedure complexity, cold slag performance and manufacture craft are all not ideal, and traditional barrel slag cooler exist the people can not enter, can not partial disassembly the drawback of maintenance.
The utility model content:
The purpose of this utility model provides double-deck breeches pipe calandria structure in a kind of novel barrel slag cooler, and it is in light weight, and has avoided many drawbacks of pressure vessel pattern, and rigidity is strong, and security is good.Because what adopt is the seamless steel pipe welding, its withstand voltage properties obviously is better than the container type structure that steel plate rolls welding, because of adopting thin-wall seamless steel pipe, and thermal resistance is little between slag, the heat conduction is fast, heat exchange performance obviously is better than other structures of steel plate roll-forming, can arbitrary parallel transistor for convenience detach unit, solved the drawback that the barrel slag cooler people can not enter, can not partial disassembly's maintenance.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of outer tube wall, inside and outside parallel transistor unit, inside and outside pocket slag blade, inside and outside pocket slag blade and internal and external screw passage.Evenly be provided with loong shunt pipe unit and outer pocket slag blade that array is circumferential arrangement in the outer tube wall, this circumference inner concentric is provided with the external spiral passage that the external spiral blade is formed.Evenly be provided with interior parallel transistor unit and interior pocket slag blade that array is circumferential arrangement in the external spiral passage again, this circumference inner concentric is provided with the inside spin passage that internal helical blades is formed.
In the utility model, outer tube wall is rotated counterclockwise, its inner concentric is equipped with the double-deck socket of loong shunt pipe unit and interior parallel transistor unit composition, slag enters the external spiral passage respectively and the inside spin passage longitudinally constantly advances, simultaneously risen, throw and raise, fall and cool off, outside the discharge machine by outer pocket slag blade and the continuous pocket of interior pocket slag blade again.The outer tube barrel structure and the interior tubular structure that are formed by parallel transistor unit circumferential arrangement in the outer tube wall can both use simultaneously, also can arbitrary layer of structure and the use of other forms of tubular structure concentric fit.
A plurality of parallel transistors unit circular array forms inside and outside two-double cylinder structure, can take two kinds of patterns of serial or parallel connection between the adjacent cells breeches pipe outlet.
When adopting the series connection form, be made up of parallel transistor unit, series connection U-shaped pipe, breeches pipe, the female pipe of water inlet and backwater mother pipe, breeches pipe one end in two ends connects by series connection U-shaped pipe, and the other end welds with the female pipe of female pipe and backwater of intaking respectively.Cooling water is entered by the female pipe of water inlet, through the parallel transistor unit, the female pipe of U-shaped pipe, backwater returns.
During the employing parallel form, be made up of parallel transistor unit, breeches pipe, the female pipe of water inlet and the female pipe of backwater, the two ends breeches pipe welds with the female pipe of female pipe and backwater of intaking respectively.The anterior breeches pipe in parallel transistor unit forms the shunt circuit with the female pipe welding of water inlet, the female pipe welding of rear portion and backwater.Cooling water is entered by the female pipe of water inlet, through the parallel transistor unit, the female pipe of backwater returns.
The utlity model has following beneficial effect:
1, in light weight more about 1/2 than domestic popular double-layer plate welding in the past, pressure vessel type double-wall structure, and avoided many drawbacks of pressure vessel pattern, rigidity is strong, and security is good.Because what adopt is the seamless steel pipe welding, its withstand voltage properties obviously is better than the container type structure that steel plate rolls welding, adopt thin-wall seamless steel pipe, and thermal resistance is little between slag, and the heat conduction is fast, and heat exchange performance obviously is better than other structures of steel plate roll-forming.
2, because seamless steel pipe is frank and outspoken, little to cooling water circulation resistance coefficient, flow process is short, can be by the cooling water of big flow, so the cooling effectiveness height.
3, owing to adopted breeches pipe to make every pair of steel pipe realize that welding in parallel forms the parallel transistor unit, the joint of being drawn by breeches pipe is directly drawn quantity than steel pipe and has been reduced 1/2, supply water female pipe and the female quantity that goes up the welding perforate of managing of backwater have been reduced, its welding capacity has also reduced more than 1/2, simplified welding procedure, cold slag performance and manufacture craft have all obtained optimization.
4, owing to the outer tube pipe structure is that several parallel transistor unit weld, connected into an integral body, so whole outer tube pipe good rigidly by helical blade, conducting strip and pocket slag blade.Outer tube pipe snugly fits into again in the outer tube wall that steel plate rolls, the auxiliary rigidity of having strengthened outer tube wall, thus the suitable attenuate of outer tube wall, the saving steel.
5, the parallel transistor unit circumferential arrangement that is welded by breeches pipe has formed a cylindrical body-socket, and the weld that the time can sever trouble unit in maintenance takes out maintenance separately, has solved the drawback that the barrel slag cooler people can not enter, can not partial disassembly's maintenance.
