Abstract
The invention provides and a kind ofly gather ptfe plastic and metal is an one, to the heat exchanger with teflon-metal composite that the heat exchange with Korrosionsmedium is handled, be characterized in common heat exchanger, touching the thick polytetrafluoroethylplastic plastic layer of all compound one deck 0.1-1mm in place of Korrosionsmedium or use polytetrafluoroethylene (PTFE).This heat exchanger can be used as the heat exchanger of the heat exchange process of industries such as chemical industry, light industry, agricultural chemicals, medicine, dyestuff.
Description
The present invention relates to a kind of heat exchanger in industrial production, relate in particular to chemical industry, light industry, pharmacy, agricultural chemicals, system alkali, dyestuff, plating and carry out the heat exchanger with teflon-metal composite of heat exchange process to having strong corrosive media in producing.
At present, the heat exchanger that is used for industrial production mostly adopts metal material, this material thermal conductivity height, heat is transmitted fast, is used as the good effect of heat exchange of heat exchanger, still, metal material resembles the not anti-highly basic of carbon steel, stainless steel, titanium, strong acid, especially not anti-strong acid and strong oxidizer.Therefore, have strong corrosive media in the presence of, heat exchanger can be corroded so that scrap very soon.Heat exchanger will shorten service life greatly.Therefore, result in hand cramps, simultaneously, cause very big economic loss and environmental pollution to production.At present, a kind of teflon heat exchanger is arranged both at home and abroad, this heat exchanger belongs to a kind of macromolecule engineering plastics, have a lot of outstanding optimum energy, good as heat resistance, except that motlten metal sodium and liquid fluorine, other all chemicals of ability, thereby teflon heat exchanger can be used to have the heat exchange exchange processing of strong corrosive media.But this heat exchanger is not high pressure resistant (withstand voltage at 3kg/cm
2Below), and non-refractory (heatproof is below 150 ℃), thermal conductivity factor is low, manufacturing process complexity, cost height.
The purpose of this invention is to provide a kind of good heat conductivity that had both had metal, high pressure resistant, have the heat exchanger with teflon-metal composite of the powerful oxidation corrosion resistance agent premium properties of plastics again.
The technical solution of the utility model is to realize like this.
Housing at common heat exchanger, heat-transfer pipe, tube sheet, end socket, Half ring, deflection plate the place that can contact with Korrosionsmedium be provided with one deck through airtight and hydraulic pressure inspection do not leak, smooth uniform polytetrafluoroethylplastic plastic layer, wherein, housing, end socket can be made lining with polytetrafluoroethylene (PTFE), Half ring is made surrounding layer with polytetrafluoroethylene (PTFE), metal tube sheets, metal heat transfer pipe can all compound one deck polytetrafluoroethylene (PTFE) in inside and outside both sides, and heat exchanger tube side, the shell side of this moment all can be walked strong corrosive media.Also can be in metal tube sheets inboard and metal heat transfer pipe inboard, end socket inboard only compound one deck polytetrafluoroethylplastic plastic layer, heat exchanger at this moment is that tube side walks to have strong corrosive media, and shell is walked the non-corrosiveness medium.Can also be only in the metal tube sheets outside, ptfe composite plastic layer outside the metal heat transfer pipe outside, housing inboard, Half ring, heat exchanger at this moment is that shell walks to have corrosive medium, tube side walks not have corrosive medium.
It is 0.3-1mm that the polytetrafluoroethylplastic plastic layer preferably is controlled at thickness.
Good effect of the present invention is: collection metal and plastics are one, and it is good to have a heat-transfer effect, and high pressure resistant (malleation is 30kg/cm
2Below, negative pressure is 2kg/cm
2Below) acid and alkali resistance, the powerful oxidation corrosion resistance agent, serviceability temperature wide (80-250 ℃ is used down), of many uses, long service life, manufacture craft is simple, has broad prospects and good economic benefit.
Manufacture craft of the present invention is: fixedly layer of even polytetrafluoroethylene film of method or electrostatic spray is twined in the external application of metal heat transfer pipe, sintering in sintering furnace, temperature is controlled at 380-450 ℃, then through range estimation and electric spark check, make it become no leak, seamless polytetrafluoroethyl-ne-ne metal composite heat-exchange pipe.Then the effective expanded joint method of the metal heat transfer in the metal composite heat exchanger tube or welding are fixed on the pore of metal tube sheets of polytetrafluoroethylene (PTFE) clad tubesheet, then the polyfluortetraethylene pipe in the heat exchanger tube outside and the interface of polytetrafluoroethylene (PTFE) outer tube plate are adopted the tin bath welding, welding temperature is 380-450 ℃, welding after airtight and hydraulic test do not leak.In the metal heat transfer pipe, make liner at last with polyfluortetraethylene pipe, behind the polytetrafluoroethyllining lining pipe flange with the polytetrafluoroethyl-ne-ne metal clad tubesheet on the liner tube sheet tie mutually, interface adopts the tin bath welding, temperature is controlled at 380-450 ℃, welding is after after airtight and hydraulic test do not leak, be assembled into heat exchanger with the housing of band teflon lined and the end socket of band teflon lined again.
Fig. 1 is the metal heat transfer pipe that has a polytetrafluoroethylene (PTFE) overclad tubes and profile after the metal tube sheets that has polytetrafluoroethylene (PTFE) outsourcing tube sheet is connected.
Fig. 2 is the metal heat exchanger tube that has polytetrafluoroethylene (PTFE) overclad tubes, an internal lining pipe and profile after the metal tube sheets that has polytetrafluoroethylene (PTFE) outsourcing tube sheet, liner tube sheet is connected.
Fig. 3 is the installation diagram (Figure of abstract) of heat exchanger with teflon-metal composite.
The present invention is described in further detail below in conjunction with accompanying drawing:
Embodiment 1: as shown in Figure 1, with metal heat exchanger tube 5 outsides fixedly layer of even polytetrafluoroethylene film of winding method, burn sintering in sintering furnace then, temperature is controlled at 380-450 ℃, through range estimation and electric spark check, form a seamless thick polytetrafluoroethylene (PTFE) overclad tubes 4 of 0.3mm on metal heat exchanger tube 5 outer walls, then, the pore of the metal tube sheets 1 by having polytetrafluoroethylene (PTFE) outsourcing tube sheet 2 is fixed on the metal heat exchanger tube 5 usefulness connection that expands on the metal tube sheets 1.Polytetrafluoroethylene (PTFE) outsourcing tube sheet 2 is connected with polytetrafluoroethylene (PTFE) overclad tubes 4, the slit of interface snarls with polytetrafluoroethylene (PTFE), tighten with glass cloth, carry out the tin bath welding then, temperature is controlled at 380-450 ℃, does not leak and can become heat exchanger with teflon-metal composite with end socket 12, the housing 8 that has teflon lined, cooling (heating) flange 9, wrapped in teflon Half ring 7,11 assemblings of polytetrafluoroethylene (PTFE) deflection plate through airtight detection.
This kind heat exchanger tube side is walked cooling water or water vapour, and shell side walks to have strong corrosive media.This kind heat exchanger can use (2kg/cm under higher malleation and high negative
2-+30kg/cm
