Problems solved by technology
[0002] In the prior art, a large number of fluids produced in the production process of power plants, steel mills, and chemical plants are generally recovered by mixing the recovered fluids to recover heat energy and working fluids. It is difficult to recover a large amount of low-pressure or even negative-pressure steam or fluids in this way. The technology is to use one fluid to recover another fluid. This recovery method requires that the pressure of the recovered fluid is greater than that of the recovered fluid, so this technology cannot recover low-pressure or negative-pressure fluid or steam; It will produce great vibration and noise, which will damage human health

Embodiment Construction
[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0030] figure 1 It is a schematic diagram of a vapor-liquid two-phase flow heating device of the present invention; as shown in the figure, the present invention is a vapor-liquid two-phase flow heating device, which includes a recovery fluid drainage pipe 2 fixed in sequence along the axis, a mixing chamber and an expansion chamber. The other end of the pressure tube 7 and the diffuser tube 7 is the fluid outlet, and the recovered fluid drainage tube 1 is placed on the side wall of the mixing chamber. The mixing cavity includes an injector 3, and the fluid inflow end of the injector 3 is fixedly connected with the recovery fluid drainage tube 2 , The fluid inj...

The invention discloses a vapor-liquid two-phase flow heating device, comprising a recovered fluid drainage pipe, a mixing cavity and a diffuser pipe which are fixedly connected in sequence along the axis, wherein the other end of the diffuser pipe is used as a fluid outlet; the recovered fluid drainage pipe is arranged on the side wall of the mixing cavity; the mixing cavity comprises an ejector; one end of the ejector is fixedly connected with the recovered fluid drainage pipe, and the end of the ejector, which is far away from the recovered fluid drainage pipe, is provided with a funnel-shaped through hole which is gradually shrunk along the flowing direction of the fluid; and the mixing cavity also comprises a network pipe, wherein one end of the network pipe is fixedly connected with the end (provided with a funnel) of the ejector, and the end of the network pipe, which is far away from the ejector, is connected with the diffuser pipe. Due to the adoption of the technical scheme, the low-pressure or negative-pressure fluid can be recovered.
Description
technical field [0001] The invention belongs to the field of boiler devices, and more specifically, the invention relates to a vapor-liquid two-phase flow heating device. Background technique [0002] In the prior art, a large number of fluids produced in the production process of power plants, steel mills, and chemical plants are generally recovered by mixing the recovered fluids to recover heat energy and working fluids. It is difficult to recover a large amount of low-pressure or even negative-pressure steam or fluids in this way. The technology is to use one fluid to recover another fluid. This recovery method requires that the pressure of the recovered fluid is greater than that of the recovered fluid, so this technology cannot recover low-pressure or negative-pressure fluid or steam; It will produce great vibration and noise, which will damage human health. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a vapor-l...
