Abstract
The invention relates to an equipment for oilfield sewage waste heat utilization, especially an anti-pressure corrosion resistance heat exchanger, which is provided with corrosion resistance, anti fouling and higher pressure bearing capability. It comprises shell 4, inlet of heat liquid 1, outlet of heat liquid 2, inlet of cold liquid 3 and outlet of cold liquid 7. Graphite block 5 is set in the shell 4. Liquid channel 6 is set on the graphite block 5 and steel skeleton is set on the graphite block 5. Cavity 8 is set between the shell 4 and the graphite block 5. Inlet of heat liquid 1, outlet of heat liquid 2, inlet of cold liquid 3 and outlet of cold liquid 7 are set on the cavity 8 correspondingly. Whereinto, inlet and outlet of heat liquid channel are gathered to corresponding cavities of inlet 1 and outlet 2 of heat liquid respectively. Inlet and outlet of cold liquid channel are gathered to corresponding cavities of inlet 3 and outlet 7 of cold liquid respectively.
Description
One, technical field: the present invention relates to the equipment of use in a kind of oilfield sewage used heat utilization, especially a kind of pressure-resistant corrosion-resisting heat exchanger.
Two, background technology: the produced-water reinjection behind the crude oil is separated in the oil field, and only Shengli Oil Field is with regard to 300,000,000 tons/year.Sewage after these crude oil separate does not generally obtain well utilizing again.In addition, about the Refrigeration Technique aspect, it is that cold-producing medium, water are the sorption type refrigerating technology of absorbent with ammonia that patent application 93201580.8 has been narrated a kind of, because ammonia water absorbing refrigerator operating pressure height, system complex, efficient is low, poisonous and it is cheap, anticorrosion not provide, factors such as nonmetallic heat exchanger antiscale, fail to be applied over 12 years.A kind of graphite-pipe heat exchanger and graphite heat tube heat exchanger have been narrated in patent application 200510104455.9,200510045231.5,200620112181.8,200620112178.6,200620112180.3, but because of its pressure-bearing is low its range of application are restricted.
Three, summary of the invention: the object of the invention be to provide a kind of corrosion-resistant, good antiscale property, bearing capacity higher be applied to pressure-resistant corrosion-resisting heat exchanger in the energy-conservation technology.Pressure-resistant corrosion-resisting heat exchanger comprises housing 4 hot fluid imports 1, hot fluid outlet 2, cold fluid import 3, cold fluid outlet 7, is provided with graphite block 5 in the housing 4, and graphite block 5 is provided with fluid passage 6, and graphite block 5 is provided with steel skeleton.The fluid passage 6 that graphite block 5 is provided with is the other layer distributed of hot and cold flow point, the layer with layer between intersect mutually, be provided with cavity 8 between housing 4 and the graphite block 5, be not communicated with respectively between the cavity 8, cavity 8 correspondences are provided with hot fluid import 1, hot fluid outlet 2, cold fluid import 3, cold fluid outlet 7, wherein the import and export of zone of heat liberation converge at hot fluid import 1, hot fluid outlet 2 corresponding cavitys respectively, and the import and export of cold fluid pass converge at cold fluid import 3, cold fluid outlet 7 corresponding cavitys respectively.Pressure-resistant corrosion-resisting heat exchanger behind the employing said structure because graphite block is the steel skeleton graphite block, can play effect anticorrosion, antiscale, can bear higher pressure simultaneously.
Four, description of drawings: accompanying drawing 1 is a structural representation of the present invention.
Five, specific embodiment: pressure-resistant corrosion-resisting heat exchanger comprises housing 4 hot fluid imports 1, hot fluid outlet 2, cold fluid import 3, cold fluid outlet 7, is provided with graphite block 5 in the housing 4, and graphite block 5 is provided with fluid passage 6, and graphite block 5 is provided with steel skeleton.The fluid passage 6 that graphite block 5 is provided with is the other layer distributed of hot and cold flow point, the layer with layer between intersect mutually, be provided with cavity 8 between housing 4 and the graphite block 5, be not communicated with respectively between the cavity 8, cavity 8 correspondences are provided with hot fluid import 1, hot fluid outlet 2, cold fluid import 3, cold fluid outlet 7, wherein the import and export of zone of heat liberation converge at hot fluid import 1, hot fluid outlet 2 corresponding cavitys respectively, and the import and export of cold fluid pass converge at cold fluid import 3, cold fluid outlet 7 corresponding cavitys respectively.
