Abstract
The utility model provides a step oil field sewage waste heat heating system, includes the dirty water heat exchanger of sewage pump, clear water cycle pump, oil field sewer line, one -level, the dirty water heat exchanger of second grade, unit clarified water pump, water source heat pump set, the oil field sewer line on ann have a sewage pump, the outlet of sewer of sewage pump and the dirty water heat exchanger's of one -level sewage entry linkage, the dirty water heat exchanger's of one -level clear water export is connected with the clear water cycle pump through the pipeline, the other end and the main pipeline connection of heating of clear water cycle pump, the dirty water heat exchanger's of one -level sewage delivery port passes through pipeline connection with the dirty water heat exchanger's of second grade sewage entry, the second grade dirty water heat exchanger be connected with water source heat pump set through the unit clarified water pump, water source heat pump set's the other end and the main pipeline connection of heating. The advantage is: a large amount of energy have been saved to being favorable to the environmental protection, putting forward heat with water source heat pump set secondary, the efficiency is up to more than 5, and traditional gas boiler efficiency is to 1, and some are with absorption formula unit efficiency only about 2.
Description
Technical field
The utility model relates to central heating system, particularly relates to a kind of step oilfield sewage waste heat for supplying system.
Background technology
Oil field produces a large amount of oil-polluted water in process of production, and the temperature of these oil-polluted waters is often higher, and the oil-polluted water of such as Shengli Oil Field can reach 57 DEG C in summer, can reach 53 DEG C in the winter time; The temperature of Daqing oil field oil-polluted water is generally at 36 ~ 42 DEG C.China oil field oil-polluted water every day has a daily output of 190 ten thousand steres (from oil field, land in 1998 statistics), and the annual oil-polluted water of offshore oilfield discharges 4,648 ten thousand tons (China marine environmental quality publications in 2000).As can be seen here, the waste heat recovery of China's oil-contaminated water of oil field has a high potential.People are paying close attention to always and how to recycle this part heat energy and come production for oil field and service for life, solve the pollution problem (simultaneously because crude oil is belong to scarce resource China, being therefore necessary to save use) because burning mineral fuel causes simultaneously.
Utility model content
For avoiding the deficiencies in the prior art, the utility model provides a kind of step oilfield sewage waste heat for supplying system.
The technical solution of the utility model is: a kind of step oilfield sewage waste heat for supplying system, comprise sewage pump, clear water circulating pump, oilfield sewage pipeline, one-level sewage heat exchanger, B-grade sewage heat exchanger, unit clarified water pump, water source heat pump units, described oilfield sewage pipeline is equipped with sewage pump, the outlet of sewer of sewage pump is connected with the sewage inlet of one-level sewage heat exchanger, the clear water output of one-level sewage heat exchanger is connected with clear water circulating pump by pipeline, the other end of clear water circulating pump is connected with heating Trunk Line, the sewage outlet of one-level sewage heat exchanger is connected by pipeline with the sewage inlet of B-grade sewage heat exchanger, B-grade sewage heat exchanger is connected with water source heat pump units through unit clarified water pump, the other end of water source heat pump units is connected with heating Trunk Line.
The beneficial effects of the utility model are: save mass energy, and are conducive to environmental protection, put forward heat with water source heat pump units secondary, and efficiency is up to more than 5, and traditional gas fired-boiler efficiency is less than 1, some absorption installation efficiencies only about 2.
