Abstract

The utility model relates to a heat exchange device of a spirally corrugated tube at the tail of an industrial boiler. A shell is fixedly arranged on a supporting leg, an inlet flue gas connecting tube is fixedly arranged at the upper end of the shell, and an outlet flue gas connecting tube is fixedly arranged at the lower end of the shell. An upper tube plate is fixedly arranged on the inner circle of the upper end of the shell, and a lower tube plate is fixedly arranged on the inner circle of the lower end of the shell. The upper end of the spirally corrugated tube is connected to the upper tube plate, and the lower end of the spirally corrugated tube is connected to the lower tube plate. A water outlet tube seat is fixedly arranged on the upper tube plate, and a blowdown tube seat is fixedly arranged on the lower tube plate. The water inlet tube seat is mounted on the lower tube plate, and a water outlet of the water inlet tube seat is placed above the lower tube plate. According to the heat exchange device of the spirally corrugated tube at the tail of the industrial boiler, compared with a traditional economizer with the same capacity, steel consumption amount is reduced by more than 50%, air leaking and dust accumulation do not happen in the operation process of the boiler, safety and reliability are achieved, and the service life is long. The heat exchange device of the spirally corrugated tube at the tail of the industrial boiler is simple in manufacturing technology and convenient to mount, lowers heat loss of flue discharging of the boiler, and improves the heat efficiency of the boiler.

Description

Industrial Boiler tailing screw flight smoke pipe heat-exchange device
Technical field
The utility model relates to a kind of Industrial Boiler tailing screw flight smoke pipe heat-exchange device, and the utility model belongs to Industrial Boiler technical field of heat exchange device.
Background technology
Traditional Industrial Boiler economizer has two kinds of steel tube economizer and cast iron gilled tube economizers.These two kinds of economizers are in operation, and tend to occur following two distinct issues comparatively.The one, Air Leakage: cast iron gilled tube economizer must be through furnace wall after installing, sealing between sealing and the economizer tube of economizer tube and furnace wall, its tightness is difficult to ensure, adds economizer and be in again the afterbody of boiler, negative pressure value is larger, cause leak out larger, strengthen air leakage coefficient, make heat loss due to exhaust gas increase, reduce boiler thermal output, and can make burner hearth form malleation when serious, and also make air-introduced machine load increase, have influence on serviceability and the security performance of boiler.The 2nd, dust stratification problem: the easy dust stratification of fin of cast iron gilled tube economizer, even if because Industrial Boiler tail heating surface is seldom used soot blower, there is too dust stratification problem in steel tube economizer.As for finned steel tube coal saving, dust stratification problem is particularly serious; Dust stratification with leak out the same, can make boiler exhaust gas heat loss increase, reduce boiler thermal output.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can solve the heat Industrial Boiler tailing screw flight smoke pipe heat-exchange device leaking out with dust stratification problem, reduction boiler exhaust gas heat loss, raising boiler thermal output recovery boiler back-end ductwork high-temperature flue gas.
The technical scheme providing according to the utility model, described Industrial Boiler tailing screw flight smoke pipe heat-exchange device, comprise into water base, housing, lower perforated plate, outlet flue gas is taken over, threaded flue, blowdown base, supporting leg, import flue gas is taken over, water outlet base and upper perforated plate, on supporting leg, be fixed with housing, be fixed with import flue gas takes in the upper end of housing, be fixed with outlet flue gas takes in the bottom of housing, in the upper end of housing, inner circle is fixed with upper perforated plate, in the bottom of housing, inner circle is fixed with lower perforated plate, the upper end of described threaded flue is connected on upper perforated plate, the bottom of threaded flue is connected on lower perforated plate, on upper perforated plate, be fixed with water outlet base, on lower perforated plate, be fixed with blowdown base, described water inlet base is arranged on lower perforated plate, the delivery port of water inlet base is positioned at the top of lower perforated plate.
In the inner circle of the middle part of housing, be fixed with pass partition, between pass partition and the inner circle of housing, there is current breach.
Described pass partition is arc, and the central angle number of degrees corresponding to this pass partition are greater than 180 ° and be less than 270 °.
The utility model steel consumption compared with same capacity boiler tradition economizer reduces more than 50%, the not safe and reliable long service life of dust stratification of not leaking out when boiler operatiopn; Manufacturing process is simple and easy for installation, has reduced boiler exhaust gas heat loss, has improved the thermal efficiency of boiler.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
This Industrial Boiler tailing screw flight smoke pipe heat-exchange device, comprise into water base 1, housing 2, lower perforated plate 3, outlet flue gas takes over 4, threaded flue 5, blowdown base 6, supporting leg 7, import flue gas takes over 9, water outlet base 10 and upper perforated plate 11, on supporting leg 7, be fixed with housing 2, be fixed with import flue gas in the upper end of housing 2 and take over 9, be fixed with outlet flue gas in the bottom of housing 2 and take over 4, in the upper end of housing 2, inner circle is fixed with upper perforated plate 11, in the bottom of housing 2, inner circle is fixed with lower perforated plate 3, the upper end of described threaded flue 5 is connected on upper perforated plate 11, the bottom of threaded flue 5 is connected on lower perforated plate 3, on upper perforated plate 11, be fixed with water outlet base 10, the import of water outlet base 10 is positioned on upper perforated plate 11, on lower perforated plate 3, be fixed with blowdown base 6, the import of blowdown base 6 is positioned on lower perforated plate 3, described water inlet base 1 is arranged on lower perforated plate 3, the delivery port of water inlet base 1 is positioned at the top of lower perforated plate 3.
In the inner circle of the middle part of housing 2, be fixed with pass partition 8, between pass partition 8 and the inner circle of housing 2, there is current breach.
Described pass partition 8 is arc, and the central angle number of degrees of these pass partition 8 correspondences are greater than 180 ° and be less than 270 °.
When use, boiler feedwater (normal-temperature water) is first entered in threaded flue heat-exchange device through water inlet base 1 by supply line, and boiler tail high-temperature flue gas evenly enters threaded flue 5 inside and enters atmosphere to exporting flue gas adapter 4 through chimney after import flue gas is taken over 9 dilatations; Boiler feedwater (normal-temperature water) produces after flow-disturbing has fully contacted heat convection with certain flow rate with threaded flue 5 outer walls from bottom to top the hot water that needs temperature is provided to water outlet base 10 to boiler through pass partition 8 under the effect of pass partition 8, thereby realize the overall process of air-water exchange heat, the waste heat of recovery boiler afterbody high-temperature flue gas.
The utility model manufacturing process is very simple, has not only substituted traditional Industrial Boiler economizer, and can extend to the field such as hot-blast stove, waste heat boiler, has suitable environmental benefit.
