Description
Technical field
The present invention relates to a kind of bushing type preheater.
Background technology
The bushing type preheater of existing design uses two pipes of size diameter to be nested together composition concentric tube, wherein,
Inner tube circulating thermal fluid, outer tube circulation cooling water.This kind of structure, the interior outside of cooling water is heated uneven, meanwhile, hot fluid
The problems such as the heat transfer of interior outside is the most uneven, causes heat exchanger effectiveness low, heat-transfer effect difference.
Summary of the invention
For the problems referred to above, the present invention provides a kind of bushing type preheater, uses multilayer sleeve structure, it is ensured that cooling water
Interior outside is heated evenly, and improves flow velocity, improves heat-transfer effect.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of bushing type preheater, including being arranged on thermal fluid inlet and the coolant outlet at top, is arranged on the hot-fluid of bottom
Body outlet and cooling water inlet, between described thermal fluid inlet and hot fluid outlet ports and cooling water inlet and coolant outlet
Between be connected by sleeve pipe, it is characterised in that described sleeve pipe include from inside to outside concentric interior-heat fluid hose, cooling water pipe and
Exterior-heat fluid hose, the two ends of cooling water pipe are connected with coolant outlet and cooling water inlet respectively, interior-heat fluid hose and exterior-heat
The two ends of fluid hose are connected with thermal fluid inlet and hot fluid outlet ports respectively.
Preferably, described sleeve pipe is in the shape of a spiral.
Or, described sleeve pipe includes several horizontal connection tubes be arrangeding in parallel, the two ends of several horizontal connection tubes
It is connected by U-shaped connecting tube.
Preferably, the material of described sleeve pipe is steel pipe.Wherein, described interior-heat fluid hose, cooling water pipe and exterior-heat fluid hose
Diameter is than for 1:2:3.
The invention has the beneficial effects as follows: the interior outside of cooling water pipe is respectively provided with interior-heat fluid hose and exterior-heat fluid hose,
Ensureing that the interior outside of cooling water is heated evenly, it addition, cooling water enters sleeve pipe from bottom, top is discharged, and hot fluid is from top
Enter sleeve pipe, bottom is discharged, and becomes cross-flow shape with cooling water respectively, improves flow velocity, improve heat-transfer effect.
Accompanying drawing explanation
