Technical field

The present invention relates to a kind of regenerators that miniature gas turbine generator uses.

Background technique

Regenerator is also known as gas-liquid heat exchanger.The refrigerant vapour come out from evaporator is utilized in freon refrigeration system The cooling highly pressurised liquid entered before evaporator is removed, a kind of heat-exchange apparatus of refrigerant liquid supercooling and steam superheating is made.

Regenerator used in miniature gas turbine is all customized product at present, and the temperature control region of this regenerator uses Integral structure, temperature region can not extend and splice, and maintenance replacement is inconvenient, so that cost and weight be caused to be unable to get into one The control of step.

Summary of the invention

The present invention provides a kind of regenerator that miniature gas turbine generator uses and is used to overcome regenerator in the prior art Weight and volume is all unable to get the defect effectively controlled.

In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:

The invention discloses a kind of regenerator that miniature gas turbine generator uses, including low-temperature space module, middle warm area moulds Block and high-temperature region module, the joining place of any two adjacent block are provided with the first retainer ring and the second retainer ring, and described Two retainer rings are socketed in the first retainer ring, and the first retainer ring inner wall is equipped with internal screw thread, and bolt passes through the first retainer ring inner wall On internal screw thread screwed in the first retainer ring.

Further, side of first retainer ring far from module is radially equipped with opening.

Further, the height of the second retainer ring is less than the first retainer ring.

Further, bolt screws in the first retainer ring, it is ensured that the leakproofness of the first retainer ring.

The beneficial effects obtained by the present invention are as follows being: this product is different configured with high, medium and low three kinds according to pressure and temperature Mould group, both can be used alone or stackable use, each mould group can define the quantity of lamination according to machine effectiveness of regenerator, have body Small, light-weight, the expansible feature of product, is more suitable for high-volume standardized production, and convenient maintenance and replacement.
