Definitions
- the invention relates to a heat exchange device, in particular to a steam heat exchange device.
- condensation and heat transfer of steam in the tube (plate) pass There are two forms of condensation and heat transfer of steam in the tube (plate) pass.
- One is film condensation; the other is bead (drop) condensation.
- the surface heat transfer coefficient of bead condensation is several times or even an order of magnitude larger than that of film condensation.
- the steam is condensed in the horizontal tube (plate) pass, which is basically a film condensation.
- the wall surface is always covered by a layer of liquid film, and the phase change heat (latent heat) released during condensation must pass through the liquid film to transfer to the cooling wall surface. Therefore, the main disadvantage of film condensation is that the thermal resistance during the condensation process is mainly concentrated in the condensate film.
- it is necessary to reduce the thickness of the liquid film, or to generate turbulence in the flowing medium.
- the structure of two or more stages of heat exchangers in series is usually used.
- the Chinese invention patent application with publication number CN104132557A discloses "an intermediate drainage type high-efficiency condensing system", which is provided with at least two-stage heat exchangers, and the rear end of the heat exchange tube of the front-stage heat exchanger is connected with the front-stage lead-out end Header, the front end of the heat exchange tube of the rear heat exchanger is connected with the rear inlet header, and the rear end is connected with the rear outlet header; the front outlet header is connected to the rear inlet header through the pipeline.
- the front-stage heat exchanger and the back-stage heat exchanger are located in the same box or in different boxes, and the lower end of the box has an air inlet, An axial flow fan is installed on the upper end.
- the intermediate drainage is implemented at the end of the front-stage heat exchanger, and the gas discharged from the front-stage heat exchanger is introduced into the back-stage heat exchanger, which is conducive to the flow of fluid in the heat exchange pipeline and accelerates the internal flow of the heat exchange pipeline.
- the discharge of the liquid film greatly increases the heat transfer coefficient.
- the liquid film Due to the increase of the vapor velocity along the flow direction of the liquid film, the liquid film will be turbulent, and on the other hand, the liquid film will be blown away from the wall surface, thereby increasing the heat transfer coefficient.
- This type of structure mainly has the following two defects: first, the heat exchange device occupies a large area, and there are many connecting pipes including headers, and the processing complexity is high. The secondary anti-corrosion process increases the difficulty of installation.
- the effect of this kind of structure is still unsatisfactory, mainly reflected in: the liquid outlet header of the upper stage and the liquid outlet header of the next stage are independent of each other, and there is a certain
- the pressure drop of the upper stage is a mixture of vapor phase and liquid phase, which is difficult to separate in the flow; They are connected, and their respective liquid outlet pipes are directly discharged. Under the action of pressure drop, part of the foam liquid flows to the next stage steam inlet header. It affects the heat exchange effect of the next stage heat exchanger.
- the technical problem to be solved by the present invention is to provide a steam heat exchanger, which greatly simplifies the pipeline structure including the header while reducing the thickness of the liquid film and improving the heat exchange efficiency, so as to occupy less space and It is more convenient to process and assemble, so as to overcome the shortcomings of the prior art.
- the steam heat exchanger is characterized in that it includes a composite header with a liquid discharge pipe, a first-stage steam inlet header and a secondary steam inlet header are arranged above the composite header, and the first-stage steam inlet header has an inlet steam header.
- Pipes; the composite header and the secondary steam inlet header are communicated through transition pipes; it also includes two groups of heat exchange pipes or heat exchange plates, wherein the inlet and outlet ends of the first group of heat exchange pipes or heat exchange plates are respectively connected to the first level
- the steam inlet header and the composite header, the inlet and outlet ends of the second group of heat exchange tubes or the heat exchange plates are respectively connected to the secondary steam inlet header and the composite header.
- the heat exchange tube is a coiled tube or a multi-stage U-shaped tube.
- the steam heat exchanger further comprises a bypass whose upper end is connected to the lower side of the first-stage steam inlet header, and the lower end is communicated with the composite header, and is used for introducing the liquid phase fluid in the first-stage steam inlet header into the composite header. Tube.
- bypass pipe is a straight pipe or a pipe with a liquid seal.
- a liquid accumulator is connected to the discharge pipe, and a balance pipe is connected between the secondary steam inlet header and the liquid accumulator.
- the steam heat exchanger further comprises an auxiliary drain pipe for connecting the composite header and the drain pipe, and the communication point between the auxiliary drain pipe and the drain pipe is higher than that between the drain pipe and the compound header The connection point is closer to the high pressure end of the composite header.
- the primary inlet steam header and the secondary inlet steam header are two sections of headers separated by the same header and separated by internal partitions.
- the most important function of the composite header of the present invention is to balance the pressure difference between the first liquid outlet end and the second liquid outlet end, which greatly improves the vapor-liquid separation effect of the first liquid outlet end.
- the efficiency of the second set of heat exchangers is improved.
- the flow velocity of the gas phase in the system is increased, thereby accelerating the discharge of the condensate film, reducing the thickness of the condensate film, and making the The fluid in the system is more likely to form turbulent flow, which improves the heat exchange efficiency.
- the entire system uses at most three headers, and in particular, one header can be divided into two sections instead of two headers.
- the device has the outstanding features of compact structure and small footprint, and can complete the anti-corrosion treatment as a whole at one time, reducing the pipeline connection installation and secondary anti-corrosion operation at the user end.
- the pressure in the first-stage steam inlet header is greater than that in the second-stage steam inlet header.
- the balance pipe connected with the accumulator is connected to the secondary steam inlet header, which can effectively reduce the internal pressure of the accumulator, which is more conducive to the liquid return of the condensing system, and can effectively reduce the temperature of the medium in the accumulator and reduce the pressure on the accumulator. Cooling workload.
- the drainage pipe can be connected to the low pressure end of the composite header for discharging the main liquid phase, and the auxiliary drainage pipe can be connected to the high pressure end of the composite header for advance. Part of the liquid phase is discharged to reduce the subsequent (second set of heat exchange tubes or heat exchange plates) load.
- the condensate and oil in the first-stage steam inlet header are introduced into the composite header in advance through the bypass pipe, thereby effectively reducing the influence of oil film and liquid film, and further improving the replacement efficiency. Thermal efficiency.
