Description
Technical field
The utility model relates to the heat exchanger that industries such as a kind of chemical industry, petrochemical industry, chlor-alkali, electric power, printing and dyeing, medical treatment are used, especially a kind of high-efficiency helical sheet heat exchanger.
Background technology
Spiral heat exchanger is a kind of high-efficiency heat exchanger equipment, and it is extensively applied in the industries such as chemistry, oil, petrochemical industry, chlor-alkali, solvent, medicine, food, light industry, weaving, metallurgy, steel rolling, coking, traffic.Existing spiral heat exchanger generally has two kinds of versions, a kind of is non-disconnectable formula spiral-plate heat exchanger, it is generally rolled by two thin plates that are parallel to each other and forms, form two spaced-apart spirality channels, at the heat exchanger center dividing plate is housed, two helical ducts are separated, the gateway that cover plate and two fluids are installed in top and bottom is taken over, see shown in Figure 2ly, its main feature has:
1, be applicable to: liquid-liquid, gas-gas, solution-air convection heat transfer' heat-transfer by convection can be used for steam condensation and liquid evaporation heat transfer, chemical industry, oil, medicine, machinery, electric power, industry such as light industry and weaving.
2, it is rolled by two steel plates and forms, and has formed two uniform helical ducts, and two kinds of heat transfer mediums can carry out full counter-current flow, is suitable for little different transfer of heat, is convenient to reclaim low-temperature heat source and can controls outlet temperature exactly.
3, the adapter on housing is a cutting orientation structure, and local resistance is little, and the curvature of helical duct is uniformly, thereby can improve design current velocity and make it to possess higher heat-transfer capability.
4, the end face of helical duct is a welded seal, good seal performance, reliable in structure.
5, being difficult for maintenance, the especially inner panel Shi Jinan that goes wrong repairs.
6, can not carry out machinery cleans.
7, because in the helical duct spacing column support passage spacing is arranged, must not there be fibrous impurity (cotton yarn, careless rod, leaf etc.) to enter heat exchanger inside.
8, strict control cooling medium outlet temperature is below the fouling temperature.
9, Chang Yong cleaning method is with steam purge or alkali cleaning, and steam is blown into and will impurity be blown out in equipment to adapter, much uses factory to think that this is an efficient ways.
In a word, though existing heat exchanger is made simply, cost is low, the little and good heat-transfer of volume, and the deficiency of its maximum can not be carried out the machinery cleaning, has gone bad difficult maintenance, and serviceability temperature has strict restriction, and the scope of application and function are comparatively single.
Another kind is a Demountable spiral-plate heat exchanger, and as shown in Figure 1, its structural principle and non-disconnectable formula heat exchanger are basic identical, but the wherein removable cleaning of passage, two ends add end socket, the intermediate cryptographic packing.Particularly suitable toughness, the liquid that precipitation liquid is arranged and liquid exchange, and gas one liquid, the steam condensation.Because removable heat exchanger need increase parts such as end socket, flange, sealing gasket, equipment cost is bigger slightly than non-disconnectable formula heat exchanger.
Though the heat exchanger of this structure can be taken cleaning apart, its structure relative complex, the scope of application is less relatively, function singleness.The two ends end socket adds the intermediate seal backing plate, and its poor sealing performance leaks easily.
Summary of the invention
The purpose of this utility model is function singleness, complex structure, the poor sealing performance that exists at existing spiral-plate heat exchanger, and easy problem of leaking designs a kind of applied widely, the novel spiral heat exchanger that resistance is little.
The technical solution of the utility model is:
A kind of spiral-plate heat exchanger, comprise low head 2, housing (14), upper cover 10, some interconnective spiral plates 9, upper cover 10, low head 2 respectively with housing (14) on, two ends link to each other down, spiral plate 9 is fixed on upper cover 10, in the housing between the low head 2 (14), be formed with cold medium channel 7 and hot media channel 8 between the spiral plate 9 and between spiral plate 9 and the housing 14, the center that it is characterized in that housing 14 is equipped with an end and communicates with cold medium channel 7 center end faces, the other end stretches out upper cover 10 outer media and imports and exports 12, the medium that communicates with cold medium channel 7 also is installed on the sidewall of housing 14 imports and exports 6, medium is imported and exported 12 and is communicated by cold medium channel 7 with medium import and export 6; A medium is installed on upper cover 10 at least imports and exports 13, a medium also is installed on low head 2 at least imports and exports 3, medium import and export 13 connect by hot media channel 8 with medium import and export 3.
Be connected by flange 4,17 between two ends of described upper cover 10, low head 2 and housing 14.
The center of the spiral plate 9 of plug-in mounting can be separated into several independently cold medium channel 7 and hot media channels 8 by reference column 18,19 mutually.On described low head, be provided with leakage fluid dram 1, on housing 8, be provided with sewage draining exit 5.
The beneficial effects of the utility model:
1, heat transfer efficiency height, few, the good seal performance of heat loss are cleaned easily, and structural safety is reliable, easy for installation, occupation of land face is little, can replace shell-and-tube and plate type heat exchanger under a lot of occasion.
2, compare with shell-and-tube heat exchanger, its heat exchange efficiency exceeds 30%-120% than shell-and-tube, compact conformation, and corrosion allowance is big, and occupation of land face is little, and cost is low.
3, compare with plate type heat exchanger, high temperature resistant, runner is wide, corrosion allowance is big, cost is low.
4, applied range can be widely used in chemical industry, oil, medicine, brewages, weaves, industry such as building, heating, metallurgy, electric power.
5, the shell-side flow resistance is minimum, and no stagnant area is difficult for dirt deposition; Prolong maintenance cycle, reduce maintenance cost; Be applicable to than viscous medium.
6, medium channel has the self-cleaning ability, less scaling and obstruction, and the cleaning frequency is longer than other pattern heat exchanger.Production practices prove that it is to be difficult for stopping up that spiral-plate heat exchanger is compared with general heat exchanger, and especially suspended particulate impurity is difficult for depositing in helical duct, analyzes its reason; The one, deposition one formation of passage impurity in passage, eddy flow will improve it is washed out, and the 2nd, there is not the dead angle in the helical duct, impurity is rushed out easily.
7, can reclaim low temperature heat energy, accurately the control medium temperature;
8, compact conformation, volume is less; Use reliably, good seal performance, reliable in structure have guaranteed that two heat exchanging fluids do not mix.
