Abstract
The utility model discloses a non-detachable spiral-plate heat exchanger, which comprises a welding-type shell, wherein the shell is provided with a thermal medium inlet, a thermal medium outlet, a cold medium inlet and a cold medium outlet; a double-spiral heat exchanging plate core body is arranged in the shell; a horn-shaped buffering transition section is arranged between the thermal medium inlet of the shell and a thermal medium inlet of the dual-spiral heat exchanging plate core body; a horn-shaped buffering transition section is arranged between the cold medium outlet of the shell and a cold medium outlet of the dual-spiral heat exchanging plate core body; a semispherical shunting lug is arranged on the spiral plate surface at the inner side of the horn-shaped buffering transition section; an impingement plate is arranged on a spiral plate at the inner side at the thermal medium inlet of the dual-spiral heat exchange plate core body; and the thermal medium entering from the thermal medium inlet of the spiral-plate heat exchanger can be rapidly shunted to the whole runner section, and therefore the heat exchanging efficiency is high.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, especially a kind of spiral-plate heat exchanger.
Background technology
The advantages such as that spiral-plate heat exchanger has is simple in structure, working stability, heat conductive efficiency are good are used for the industries such as Chemical Manufacture, alcohol manufacturing by wide model.The thermal medium import of spiral-plate heat exchanger of the prior art and cold media outlet to be adopted with the connecting box of the width such as the spiral plate medium import or export corresponding with double helix heat exchange plate core body and is connected, because the diameter of thermal medium import and cold media outlet is much smaller than the width of connecting box, therefore, the thermal medium that enters from the thermal medium import can not promptly be distributed in the whole runner, there is the dead band at connecting box two end regions, affects heat transfer effect.In addition, in order to improve the heat transfer coefficient of spiral-plate heat exchanger, usually the mode of taking to improve the medium designs flow velocity reaches turbulent heat transfer, therefore, when thermal medium enters at a high speed double helix heat exchange plate core body, can produce strong washing away to the spiral plate of the thermal medium import department inboard of double helix heat exchange plate core body, form erosion corrosion face at the spiral plate face, make spiral plate herein damaged at first, thereby affect the whole service life of spiral-plate heat exchanger.
The utility model content
The technical problem that utility model will solve: a kind of non-disconnectable formula spiral-plate heat exchanger is provided, and the thermal medium that enters from this spiral-plate heat exchanger thermal medium import can be diverted to rapidly whole runner section, and heat exchange efficiency is high.
The technical scheme that the technical solution problem is taked: a kind of non-disconnectable formula spiral-plate heat exchanger, comprise the welded type housing, be provided with thermal medium import, thermal medium outlet, cold medium import, cold media outlet at housing, in housing, be provided with double helix heat exchange plate core body, between the thermal medium import of thermal medium import and double helix heat exchange plate core body, be provided with tubaeform buffering changeover portion.
As further improvement of the utility model: between the cold media outlet of cold media outlet and double helix heat exchange plate core body, be provided with tubaeform buffering changeover portion.
Further improve as of the present utility model: the spiral plate face in tubaeform buffering changeover portion inboard is provided with hemispherical shunting projection again.
As another kind of improvement the of the present utility model: the spiral plate in the thermal medium import department inboard of double helix heat exchange plate core body is provided with impingement baffle.
As of the present utility model preferred: take the impingement baffle cross section as fan-shaped central angle that arc was consisted of as 90-180 degree.
Take the impingement baffle cross section as 130 degree as fan-shaped central angle that arc was consisted of.
As another improvement of the present utility model: be provided with exhaust outlet on housing top, be provided with sewage draining exit in lower housing portion.
Beneficial effect: non-disconnectable formula spiral-plate heat exchanger of the present utility model is owing to having adopted described non-disconnectable formula spiral-plate heat exchanger to comprise the welded type housing, be provided with the thermal medium import at housing, the thermal medium outlet, cold medium import, cold media outlet, in housing, be provided with double helix heat exchange plate core body, between the thermal medium import of thermal medium import and double helix heat exchange plate core body, be provided with the technical scheme of tubaeform buffering changeover portion, make the thermal medium that enters from the thermal medium import can be diffused into rapidly whole runner section by between the thermal medium import of thermal medium import and double helix heat exchange plate core body, being provided with tubaeform buffering changeover portion, reduce thermal medium at a high speed to the impact of spiral plate part, overcome spiral-plate heat exchanger of the prior art easily forms the heat exchange dead band at the connecting box place drawback, improved the heat exchange efficiency of spiral-plate heat exchanger; Owing to having adopted the technical characterictic that between the cold media outlet of cold media outlet and double helix heat exchange plate core body, is provided with tubaeform buffering changeover portion, also having avoided near the connecting box of cold media outlet, occurring the heat exchange dead band; Owing to having adopted the spiral plate face in tubaeform buffering changeover portion inboard to be provided with the technical characterictic that hemispherical is shunted projection, utilize on the one hand the shunting projection that the shunting of homogeneous media ground is opened, utilize on the other hand the flow-disturbing effect of shunting projection to make the medium that enters form rapidly turbulent flow, therefore, the heat exchange efficiency of non-disconnectable formula spiral-plate heat exchanger of the present utility model obviously is better than common non-disconnectable formula spiral-plate heat exchanger; Be provided with the technical characterictic of impingement baffle owing to the spiral plate that has adopted the thermal medium import department inboard of double helix heat exchange plate core body, strengthened shock-resistant, the corrosion resistance of local spiral plate, the whole service life of spiral-plate heat exchanger is prolonged; Owing to reasonably defining take the angle of impingement baffle cross section as the fan-shaped central angle that arc was consisted of, making cost, heat exchange efficiency, the Anti-erosion effect three of impingement baffle reach perfect unity; Owing to having adopted on housing top to be provided with exhaust outlet, be provided with the technical characterictic of sewage draining exit in lower housing portion, made things convenient for routine use and the maintenance of non-disconnectable formula spiral-plate heat exchanger.
