Abstract
A double helix exchanger for an ejected fluid comprises a barrel-shaped outer casing, wherein an ejecting nozzle coaxially arranged with the outer casing is mounted inside the outer casing; the front end of the ejecting nozzle is fixed onto the inner wall of the outer casing; the middle of the ejecting nozzle is a low-diameter section; a double helix groove is formed in the inner wall of the low-diameter section; a low pressure fluid inlet is formed in the outer casing at the downstream position of the fixed part of the ejecting nozzle; the low pressure fluid inlet is communicated with an outlet of the ejecting nozzle; a low-diameter fluid tube is arranged at the outlet of the ejecting nozzle; the inlet of the low-diameter fluid tube is internally conical; the outlet of the low-diameter fluid tube is tubaeform; the middle of the low-diameter fluid tube is a straight tube with a constant diameter; a spiral diversion trench is formed in the inner wall of the straight tube. The double helix exchanger for the ejected fluid omits a low pressure liquid pipeline; the diversion trench is adopted to promote the heat exchanging when the high pressure fluid and the low pressure fluid are mixed, so that the high pressure fluid and the low pressure fluid are fully mixed, the heat exchanging efficiency is increased, the overall structure is simple, and the occupied space is small.
Description
Technical field
The present invention is that a kind of double-screw type sprays fluid interchanger, belongs to injecting type heat exchanger field.
Background technology
Injecting type heat exchanger be a kind of be injector take heat exchange as object, be that pressure, two kinds of fluids that temperature is different are mixed mutually, and in mixed process, carry out the equipment of energy exchange.According to mixed fluid difference, can be divided into vapour-water interchanger, water-water interchanger, vapour-vapour interchanger etc.Wherein vapour-water interchanger, huge structure, heat exchanger effectiveness is low, and jet mixing is even not, causes that operating efficiency is low on the whole.
Summary of the invention
The object of this invention is to provide a kind of double-screw type and spray fluid interchanger, guarantee that heat exchanger turns round efficiently, save space.
Object of the present invention is carried out specific implementation by the following technical programs:
Double-screw type sprays fluid interchanger, comprise the external shell of straight-tube shape, jet nozzle with the coaxial setting of external shell is installed in the inside of described external shell, described jet nozzle front end is fixed on the inwall of external shell, the middle part of jet nozzle is thin diameter section, and be provided with double spiral groove on the inwall of described thin diameter section, on the external shell in downstream, jet nozzle fixed position, be provided with low-pressure fluid entrance, described low-pressure fluid entrance communicates with the outlet of described jet nozzle, the exit position of described jet nozzle is provided with thin footpath fluid hose, the entrance of described thin footpath fluid hose is inner conical, outlet is for tubaeform, centre is isometrical straight tube, on the inwall of straight tube, be provided with spiral guiding gutter.
The double-screw type of above-mentioned design sprays fluid interchanger, has omitted low-pressure fluid pipeline, promotes the mixing of high pressure, low-pressure fluid by guiding gutter, improves heat exchanger effectiveness, simple in structure on the whole, takes up room little.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structure chart that double-screw type sprays fluid interchanger described in the embodiment of the present invention.
The specific embodiment
As shown in Figure 1, described in the embodiment of the present invention, double-screw type sprays fluid interchanger, comprise the external shell 1 of straight-tube shape, jet nozzle 2 with the coaxial setting of external shell 1 is installed in the inside of described external shell 1, described jet nozzle 2 front ends are fixed on the inwall of external shell 1, the middle part of jet nozzle 2 is thin diameter section, and on the inwall of described thin diameter section, be provided with double spiral groove 3, on the external shell 1 in jet nozzle 2 downstreams, fixed position, be provided with low-pressure fluid entrance 4, described low-pressure fluid entrance 4 communicates with the outlet of described jet nozzle 2, the exit position of described jet nozzle 2 is provided with thin footpath fluid hose 5, the entrance of described thin footpath fluid hose 5 is inner conical, outlet is for tubaeform, centre is isometrical straight tube, on the inwall of straight tube, be provided with spiral guiding gutter 6.
The double-screw type of above-mentioned design sprays fluid interchanger, has omitted low-pressure fluid pipeline, promotes the mixing of high pressure, low-pressure fluid by guiding gutter, improves heat exchanger effectiveness, simple in structure on the whole, takes up room little.
