Description
Technical field
The utility model relates to a kind of novel economizer.
Background technology
For the contour heat evacuator of boiler, containing a large amount of waste heats in its waste gas of discharging, cause the loss of heat, some producer carries out heat recovery by arranging economizer in exhaust emission tube road at present, common heat exchanger tube is generally in economizer, heat transferring medium is utilized to be collected by the heat in waste gas, because the diameter in exhaust emission tube road own is less, when adopting many heat exchanger tubes because its volume to affect the normal discharge of waste gas compared with conference; When heat exchanger tube negligible amounts, heat collection is not obvious.
Summary of the invention
For the defect existed in prior art, the utility model provides a kind of novel economizer, and it collects heat ability by force, and can not affect the normal discharge of waste gas.
Concrete technical scheme is: a kind of novel economizer, comprise housing and be arranged at the two longitudinal external symmetry finned tube in housing, housing is the hollow structure of left and right opening, and the diameter of housing both ends open is less than the diameter of housing central section, two longitudinal external symmetry finned tube comprises base tube and endothermic tube, base tube is snakelike distribution in housing, its sweep is positioned at housing rear and front end, endothermic tube is symmetrical and be horizontally placed on the left and right sides of base tube straight portion, endothermic tube longitudinal cross-section is rectangle, endothermic tube is hollow structure, endothermic tube is communicated with base tube, endothermic tube upper and lower end face is provided with equally distributed arc boss, the bearing of trend of arc boss and the axial vertical of endothermic tube.
On front side of the axis of described base tube, base tube on rear side of the axis of endothermic tube and base tube the axis of endothermic tube in same plane.
Described arc boss section is " bow " shape, and the central angle corresponding to " bow " shape is 180 °.
The utility model structure is simple, low cost of manufacture, and housing central section diameter is greater than its two ends diameter, slows after waste gas enters, and is conducive to and the abundant heat exchange of two longitudinal external symmetry finned tube; In base tube, pass into conductive fluid, increase the contact area with waste gas by endothermic tube, be conducive to heat absorption; Endothermic tube is communicated with base tube, and the Rapid Thermal being convenient to conductive fluid and waste gas exchanges; Simultaneously waste gas is because the existence of endothermic tube prevents waste gas from producing vortex phenomenon after by base tube surface, thus is conducive to passing through of waste gas.

Detailed description of the invention
As shown in Figures 1 to 5, a kind of novel economizer, the two longitudinal external symmetry finned tube 6 comprising housing 5 and be arranged in housing 5, housing 5 is the hollow structure of left and right opening, and the diameter of housing 5 both ends open is less than the diameter in the middle part of housing 5, two longitudinal external symmetry finned tube 6 comprises base tube 1, left endothermic tube 2 and right endothermic tube 4, base tube 1 is snakelike distribution in housing 5, its sweep is positioned at housing 5 rear and front end, left endothermic tube 2 and right endothermic tube 4 are symmetrical and be horizontally placed on the left and right sides of base tube 1 straight portion, left endothermic tube 2 and right endothermic tube 4 longitudinal cross-section are rectangle, left endothermic tube 2 and right endothermic tube 4 are hollow structure, left endothermic tube 2 is communicated with base tube 1 respectively with right endothermic tube 4, left endothermic tube 2 and right endothermic tube 4 upper and lower end face are provided with equally distributed arc boss 3, the bearing of trend of arc boss 3 and left endothermic tube 2 are axial vertical with right endothermic tube 4.
On front side of the axis of base tube 1, base tube 1 on rear side of the axis of endothermic tube and base tube 1 axis of endothermic tube in same plane.
Arc boss 3 section is " bow " shape, and the central angle corresponding to " bow " shape is 180 °.
The utility model structure is simple, low cost of manufacture, and housing 5 mid diameter is greater than its two ends diameter, slows after waste gas enters, and is conducive to and the fully heat exchange of two longitudinal external symmetry finned tube 6; In base tube 1, pass into conductive fluid, increase the contact area with waste gas by endothermic tube, be conducive to heat absorption; Endothermic tube is communicated with base tube 1, and the Rapid Thermal being convenient to conductive fluid and waste gas exchanges; Simultaneously waste gas is because the existence of endothermic tube prevents waste gas from producing vortex phenomenon after by base tube 1 surface, thus is conducive to passing through of waste gas.
