Abstract
A mesh-tube heat exchanger for vapour-liquid or liquid-liquid heat exchange is composed of stainless steel meshes and worm pipes through dot welding to combine them together. Its advantages are small size, great heat transfer area, and high heat efficiency.
Description
Heat exchanger is a kind of fluid that will carry heat energy, pass to the equipment of another kind of cold fluid by wall, so both can be used as heater, also can be used as condenser, cooler, cold hydrazine and be widely used in chemical industry, light industry, oil, food, pharmacy, biochemical industry or the like industry, be use very common, commonly used, also be that power consumption is maximum in vapour-liquid, the liquid-liquid heat transfer process, but requisite equipment.According to feed liquid Calculation of Physical Properties thermic load and heat transfer area, how energy-conservation and improve the unit volume heat exchange efficiency, it is big again to make the little heat exchange area of volume, it is the main target of design heat exchanger, many various rerum naturas that are suitable for have been formed for this reason, the heat exchanger of multiple pattern has tubular heat exchanger, tube-in-tube heat exchanger, helix tube heat exchanger, spiral heat exchanger, plate heat exchanger, heat-exchangers of the plate type, also has mechanical rotary heat exchanger etc.
The present invention " net-pipe type heat exchanger " be a kind of vapour-liquid that is suitable for, the novel heat exchanger of liquid-liquid heat transfer process (figure one), utilize that not repair steel woven wire specific area big, thermal conductivity factor is again much larger than gas, the characteristic of liquid, with wire mesh sheet and helix tube spot welding alternate combinations, logical refrigerant medium in the helix tube, utilize the metal heat-conducting coefficient to be higher than the characteristic of vapour-liquid far away, each sheet woven wire is close to is welded to each circle helix tube outer tube wall, form new heat exchange wall, thus at certain spatial volume, obtain big as far as possible wall heat exchange area, it is little to make volume, heat transfer area is big, the novel heat exchanger that the thermal efficiency is high-" net-pipe type heat exchanger ".Net-pipe type heat exchanger can be required according to the technological process of production, makes horizontal (figure one) or vertical (figure two) configuration, and can be used as the cold hydrazine of high vacuum distillation, short-path distillation or quasimolecular distillation system.The present invention's " net-pipe type heat exchanger " is simple in structure, both available full welding method is made little, the lightweight heat exchanger of volume, shown in figure one figure two, also can make band and link flange (figure three M, M ' are detachable big flange) net-pipe type heat exchanger according to vapour-liquid situation (regularly cleaning) as needs.
The present invention " net-pipe type heat exchanger " (figure one, figure two) by cylindrical shell (T) gas entrance sleeve (Q1), gas vent take over that (Q2), condensate outlet take over that (Y), cold medium entrance sleeve (L1), cold media outlet are taken over (L2), coil pipe (B1), coil pipe (B2), when above (two groups be the n+1 coil pipe), do not repaiied steel wire wire netting sheet group C, baffling baffle (A), baffling baffle (A ') form.After the coercibility gas enters from gas entrance sleeve (Q1),, take over (Q2) from gas vent and enter the vacuum suction unit by baffling route shown in the figure one.The coercibility gas is in webmaster formula heat exchanger during overcurrent, heat exchange area by many networkings (C)-pipe (B) assembly and baffling baffle (A, A ') process, be 5 times with volume shell and tube or helix tube heat exchanger, (with figure two vertical webmaster formula heat exchangers, if the cold hydrazine as short-path distillation or quasimolecular distillation is an example, the steel cold hydrazine of not repairing that is used for the industrialized unit Dg800 of the several factory of XX at present is: heat transfer area 12m
2, external diameter 600mm, high 1700mm, weight～220Kg, shared spatial volume is: diameter 0.6m, the about 0.48m of high 1.7m
3Identical heat exchange area 12m
2Net-pipe type heat exchanger weight be～142Kg shared spatial volume: diameter 0.35m, high 1m accounts for 096m
3, its shared spatial volume only for the former 1/5).During net-pipe type heat exchanger coercibility gas overcurrent of the present invention, because being close to the mash welder point, each circle of net and helix tube is welded into one, so diabatic process between net sheet and the helix tube outside wall surface, basically can think the heat conduction between the metal, and the coercibility gas of overcurrent, by little spatial volume like this, but be big contact area like this, overcurrent vaporized molecules and net-pipe metal surface spacing is shortened greatly, optimized diabatic process, heat exchanging process speed is greatly improved, and the heat transfer process of having optimized makes the influence of tube pitch ease down to bottom line.
With present industrialization bushing type, shell and tube, helix tube, spiral heat exchanger ratio, the present invention's " net-pipe type heat exchanger " has following advantage:
1. volume is little, and is in light weight, and each wire side and each helix tube periphery are adjacent to spot-welded on and are integral, and the heat exchange effect is significantly optimized.
2. energy-saving effect is significantly better than the heat exchanger of present standard.
3. identical heat exchange area material therefor, only be present standard heat exchanger half, this does not repair steel heat exchanger cost of manufacture to reducing, and very big influence is arranged.
4. because shared spatial volume only is heat exchanger～1/5 of present standard, as design short-path distillation or quasimolecular distillation cold hydrazine the time, possessed with the condition of distiller consubstantiality making in aggregates (accepted application for a patent for invention number :) and, reduced investment to optimize operating system.
5. because volume is little, in light weight, so be convenient to combination, dismounting, cleaning.

Claims (3)
1. one with wire wire side and each helix tube cylindrical wall, is adjacent to spot-welded on all-in-one-piece heat exchanger inner structural members assembly.
2. one with wire wire side and each helix tube cylindrical wall, be adjacent to that spot-welded on all-in-one-piece, every wire side external diameter and simplified internal face are close to, have up and down or left-right symmetry is joined the inside assembly of the drainage baffle of Fabric at certain distance, there is gas to import and export adapter, the adapter of cold media outlet, condensate outlet adapter with outside weldings, with the net-pipe type heat exchanger that welds or bolt assembles.
3. one kind both can be used as general vapour-liquid, liquid-tuck in heat exchanger, also can be used as cold hydrazine and was used for short-path distillation or quasimolecular distillation or makes the net-pipe type heat exchanger of one with short-path distillation, quasimolecular distillation.
