27, three-level heat exchanger 29 and controller 32 form, and workflow is broadly divided into three parts to complete sewage remaining energy recycling again
It utilizes, i.e. level-one heat exchange, secondary heat exchange and three-level heat exchange.
First, level-one heat exchange is about 50 DEG C of the inlet temperature of crude oil, then by dehydration heat exchanger 3 and heating furnace 5
Heating so that about 60 DEG C of crude exports temperature, and be dehydrated the heat exchange tubing of heat exchanger 3 and imitated using corrosion-resistant, high heat transfer
The corrugated tube of rate solves structure obstruction, etching problem, and efficient, then, the filtering by filter 8 and three-phase
Crude oil after the separation of separator 10, about 70 DEG C or so sewage of the temperature then isolated from settling tank 19 divide with three phase separator 10
About 50 DEG C or so sewage of the lower temperature separated out are mixed to form 60-65 DEG C of sewage.It is changed with generated crude oil in oil well 1
Heat is entered by first-class heat exchanger 12 in surge tank 14, is recycled water filling device 16 to realize sewage addition, is reached daily and work
Thermal energy needed for industry, temperature are controlled at 40 DEG C or so, and advance is：Technique uses new-type gas fired-boiler when environment temperature is low
There is provided three phase separation institute calorific requirement for the liquid that comes in oil well 1, when environment temperature is high technological process only use new-type gas fired-boiler and be
Production provides heat on standing, and crude oil is entered from liquid efferent duct 2 is carried out in oil well 1 by oil well in dehydration heat exchanger 3, in this way can be with
Reach and only meet the upper production requirement in station with natural gas and electric energy, and daily production run loss can be reduced, is entire oil recovery factory
Reduce operating cost.Heating furnace 5 therein is vacuum hot water boiler, it can be tied in cold operation under negative pressure state, securely and reliably
Structure is compacter, possesses noise, exhaust gas discharges the advantages that extremely low；Expansion valve 6 uses thermal type expansion valve, can survey water according to cold water
Temperature and unit operation situation automatically adjust refrigeration machine；Filter 8 uses automatic cleaning strainer, it solves filtering oil-based liquid
When, net wall generates the problems such as oil film causes in obstruction net and oil-polluted water containing high molecular polymer.
Secondly, secondary heat exchange is the crude oil after the filtering of filter 8 and three phase separator 10 detach, using sedimentation
Tank 19, the crude oil finally exported by oil storage tank 21, about 60 DEG C of inlet temperature, using secondary heat exchanger 23, outlet temperature
