Abstract
The invention discloses an efficient anti-plugging heat exchanger which comprises a barrel, an upper end socket, an upper tube plate, a lower end socket and a lower tube plate. The lower end socket is provided with a material inlet. The upper end socket is provided with a material outlet. A plurality of heat tubes are arranged in the middle of the barrel. The upper ends of the heat tubes penetrate through the upper tube plate and are communicated with the material outlet. The lower ends of the heat tubes penetrate through the lower tube plate and are communicated with the material inlet. The upper end of the barrel is provided with a steam inlet. The lower end of the barrel is provided with a condensate outlet. Each heat tube is provided with at least one outer flow-dividing portion. Each outer flow-dividing portion comprises at least one flow-dividing tube. All the flow-dividing tubes are evenly distributed in the circumferential direction of the heat tubes and communicated with inner cavities of the heat tubes. A part of liquid and steam mixtures can be divided through the arranged outer flow-dividing portions, the liquid and steam mixtures can be prevented from being directly discharged through the material outlet, and the overall rectification and purification efficiency is improved.
Description
Technical field
The present invention relates to a kind of high efficient block heat exchanger.
Background technology
Heat exchanger common application is in petrochemical industry, in the synthetic liquid material rectification and purification process of chemical industry, often be used in conjunction with rectifying column, its structure is similar to condenser, its primary structure is such, lower perforated plate on establishing in heat exchanger, intensive perforate on tube sheet, weld heating tubulation in hole, heating tubulation is to the upper and lower both ends open of heat exchanger, the space forming between upper lower perforated plate is heating space, pass into heat medium, to heating tube heating wherein, because material enters from heat exchanger lower end material inlet, be filled with liquid material storage space, heat exchanger lower end and heating tubulation, material to be vaporized in heating tubulation is just subject to thermal evaporation, enter rectifying column fractionation.
In heat exchanger traditionally, heat pipe is fairly simple, material to be processed is heated in pipe, if the process of heating is comparatively violent, material steam after a large amount of liquid materials is vaporized often sweeps along the material upper punch of not yet vaporization to heat exchanger upper perforated plate upper end, so that enter rectifying column, affect system rectification and purification efficiency, hidden danger even causes the accident.
Summary of the invention
The invention provides a kind of high efficient block heat exchanger.
The technical solution adopted in the present invention is to achieve the above object of the invention: a kind of high efficient block heat exchanger, comprise cylindrical shell, upper cover, upper perforated plate, low head and lower perforated plate, material inlet is set on low head, material outlet is set on upper cover, the middle part of cylindrical shell arranges some heat pipes, and the upper end of heat pipe is communicated with material outlet through upper perforated plate, and the lower end of heat pipe is communicated with material inlet through lower perforated plate, cylindrical shell upper end arranges steam inlet, and the lower end of cylindrical shell arranges condensate outlet;
On described every heat pipe, be provided with external shunt portion of at least one place, this external shunt portion comprises at least one isocon, and each isocon is circumferentially uniform and communicate with heat pipe inner chamber along heat pipe.
Further, be positioned at one section of radial expansion portion of heat pipe formation of external shunt subordinate side.
Further, described radial expansion portion is bullet structure.
Further, described isocon bending forms arcuate structure.
The invention has the beneficial effects as follows: can fall part liquid vapour mixing portion by splitter section by the external shunt portion arranging, can avoid these liquid gas mixing portions directly to discharge from material outlet, improve whole rectification and purification efficiency.

Detailed description of the invention
As shown in Figure 1, a kind of high efficient block heat exchanger, comprise cylindrical shell 1, upper cover 2, upper perforated plate, low head 3 and lower perforated plate, material inlet 31 is set on low head 3, material outlet 21 is set on upper cover 2, the middle part of cylindrical shell 1 arranges some heat pipes 4, the upper end of heat pipe 4 is communicated with material outlet 21 through upper perforated plate, the lower end of heat pipe 4 is communicated with material inlet 31 through lower perforated plate, and cylindrical shell 1 upper end arranges steam inlet 11, and the lower end of cylindrical shell 1 arranges condensate outlet 12.
On every heat pipe 4, be provided with 2 external shunt portions of place 5, lay respectively at the upper and lower of heat pipe 4, this external shunt portion 5 comprises at least 4 isocons 51, and isocon 51 bendings form arcuate structure.Arcuate structure is convenient to material stream passed, and each isocon 51 is circumferentially uniform and communicate with heat pipe 4 inner chambers along heat pipe 4.
The heat pipe 4 that is positioned at external shunt portion 5 belows forms one section of radial expansion portion 52.Radial expansion portion 52 is bullet structure.The Main Function of this radial expansion portion 52 is, in the time that liquid gas mixing portion rises together, through changing liquid gas mixture velocity in radial expansion portion 52, and there is deformation in liquid gas mixing portion, be separated thereby make to be included in inner liquid, then help heat pipe 4 to shunt at the isocon 51 through top, thereby liquid part can be vaporized fully, avoid stopping up, improve the effect of rectifying.
Heat exchanger of the present invention utilizes radial expansion portion 52 to make the mobile generation of materials inside deformation, thereby makes fluid separation applications go out to vaporize, and utilizes external shunt portion 5 to make material have more heating surface, improves heating effect.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just can design according to the present invention make many modifications and variations without creative work.Therefore, all technical staff in the art on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should fall within the scope of protection of the present invention under this invention's idea.
