Abstract
The utility model relates to a pressure-proof teflon heat exchanger, which comprises a casing, arrayed heat exchange tube fixed in the casing and teflon rings fixed on the two end of the arrayed heat exchange tube. A plurality of arrayed heat exchange tubes piles up through the teflon rings; collets are provided between the casing and outer surface of the teflon rings fixed on the two end of the arrayed heat exchange tube; material feeding and discharging ports connected with the inside of the casing are provided on the casing; media inlet and outlet connected with the collets are provided on the casing; and an anticorrosion telfon layer is compounded on the metal wall of the arrayed tube. The utility model has reasonable structure, big pressure-proof capacity, which can reach -0.1 to +1.3MPa and the coefficient of heat transfer is 50% higher than the average teflon arrayed-tube heat exchanger with 150kilocalorie/m2. The heat exchange area inside of the heat exchanger has bigger proportion with 80m2 more within the per m3 equipment volume. The range of the operation temperature is -20 to +200 Celsius system.
Description
Technical field:
The utility model relates to a kind of heat exchanger.
Background technology:
The severe corrosive chemical substance is heated or cools off, need the heat exchanger of tetrafluoro material, these type of all so far heat exchangers are the tetrafluoro tubular heat exchanger, and its tetrafluoro tubulation can't bear higher pressure, cause to satisfy actual needs.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and voltage endurance capability is big, the withstand voltage tetrafluoro heat exchanger of good effect of heat exchange.
Technical solution of the present utility model is:
A kind of withstand voltage tetrafluoro heat exchanger, it is characterized in that: comprise housing, dress heat exchanging pipe in the housing, the two ends dress fluoroplastics circle of heat exchanging pipe, a plurality of heat exchanging pipes coincide by the fluoroplastics circle at two ends mutually, and the chuck for communicating with tubulation between the outer surface of housing and multilayer tubulation two ends fluoroplastics circle is provided with the material import and export that communicates with the housing inner chamber on the housing, the medium import and export that communicates with chuck is set, the outer compound fluorine plastic corrosion-proof layer of the metal pipe-wall of tubulation on the housing.
Housing adopts steel material, compound rotten plastic layer on loam cake, bottom outer surface.
The utility model is rational in infrastructure, voltage endurance capability is big, can be anti--0.1～+ operating pressure of 1.6MPa, the comparable common tetrafluoro tubular heat exchanger of its coefficient of heat transfer improves 50%, reach 150 kilocalories/square metre more than, the heat exchanger area ratio of arranging in the heat exchanger is big, and heat exchange area can reach more than 80 square metres in every cubic metre of equipment volume, and anti-operating temperature reaches-20 ℃～+ 200 ℃.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the sectional view of heat exchanging pipe among Fig. 1.
The specific embodiment:
A kind of withstand voltage tetrafluoro heat exchanger, comprise housing 1, dress heat exchanging pipe 2 in the housing 1, the two ends dress fluoroplastics circle 3 of heat exchanging pipe 2, a plurality of heat exchanging pipes 2 coincide by the fluoroplastics circles 3 at two ends mutually, the chuck 4 for communicating with tubulation between the outer surface of housing 1 and multilayer tubulation two ends fluoroplastics circle, the material import and export 5,6 that setting communicates with the housing inner chamber on the housing 1, the medium import and export 7,8 that communicates with chuck 4 is set, the metal pipe-wall 9 outer compound fluorine plastic corrosion-proof layers 10 of tubulation on the housing 1.Housing adopts steel material, compound rotten plastic layer 11 on loam cake, bottom outer surface.Also have deflection plate 12, inner seal liner 13 among the figure.Described fluoroplastics can be materials such as F4, F46, PFA.During the utility model work, shell side is walked material, and tube side is walked steam, conduction oil (or chilled water).
