Description
Technical field
This utility model belongs to petrochemical industry aid, relates to a kind of sampling type crude oil water content on-line detector。
Background technology
Oilfield exploitation, collect in defeated, crude Treatment and oil-refining chemical process, it is necessary to the crude oil water content in conveyance conduit is measured。Currently used measurement crude oil water containing metering method kind is a lot, and principle and structure are different。Main method has: hand sample, ionization dehydration or way of distillation algoscopy, densimeter method, gamma-rays method, capacitance method, radio frequency is sent out, shortwave method and microwave method etc.。But each method has certain drawback, as: precision is not high, range receives restriction, be easily subject to big, the easy contaminated environment of impact etc. of interference, oil product physico-chemical property。It addition, no matter adopt any measuring method except hand sample method, the factor such as temperature, pressure, density, silt content, air content, salinity, emulsifying degree, moisture content scope, oil composition can directly affect measurement result。And, the randomness of above parameter is very strong, very low by the probability of coefficient correction, makes measurement result not have value thus increasing error。
The sampling type crude oil water content on-line detector that this utility model provides is a kind of on-line Full measuring instrument。Utilize continuous sampling, continuous oil-water separation, the You Heshui separated be continuously drained into the downstream of measured pipeline；The pure water separated and pure oil are measured simultaneously, teletransmission record, calculating, the means such as error correction, calculate some time period conveying crude oil average function rate (by the hour, by order of classes or grades at school, by whole day or point thinner)。The sampling type crude oil water content on-line detector that this utility model provides has the following advantages: have employed the crude oil sampling chemical examination mode that generally acknowledged certainty of measurement is the highest；Overcome the shortcoming that manual chemical examination workload is heavy；Overcome the discontinuity of hand sample chemical examination；Whole measurement process does not have pollutant；Adaptive capacity is very strong, broad quantum, by temperature, pressure, gassiness, impact containing sand, fouling, crude oil physico-chemical property and salinity；Principle is simple, installs, easy to use, and maintaining is less demanding；Precision is high。
Summary of the invention
The purpose of this utility model is in that to provide a kind of sampling type crude oil water content on-line detector, and simple in construction, easy to install and use, precision is high, can solve the sampling type crude oil water content on-line detector of an on-line measurement crude oil moisture difficult problem。
The purpose of this utility model is achieved in that a kind of sampling type crude oil water content on-line detector, including sampling pump, oil water separator, heating rod, drug feeding device, oil-water interface tool, three-way magnetic valve door, control circuit and computer control system；Sampling pump input is connected with tested oil pipeline, sampling pump outfan is connected with oil water separator input, oil-water interface tool, heating rod and two drug feeding devices it are provided with inside oil water separator, two outfans of oil water separator are connected with two inputs of three-way magnetic valve door respectively, three-way magnetic valve gate output terminal is connected with tested oil pipeline downstream, control circuit is connected with sampling pump, oil-water interface tool, heating rod and drug feeding device and three-way magnetic valve door, and computer control system is connected with control circuit。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail。
Fig. 1 is this utility model structural representation。
Detailed description of the invention
As shown in drawings, a kind of sampling type crude oil water content on-line detector, including sampling pump, oil water separator, heating rod, drug feeding device, oil-water interface tool, three-way magnetic valve door, control circuit and computer control system。
Sampling pump 2 input is connected with tested oil pipeline 1, and sampling pump 2 outfan is connected with oil water separator 3 input。
Oil water separator 3 is internal is provided with oil-water interface tool 4, heating rod 10 and two drug feeding devices 8,9, and two outfans of oil water separator 3 are connected with two inputs of three-way magnetic valve door 5 respectively, and three-way magnetic valve door 5 outfan is connected with tested oil pipeline 1 downstream。
Control circuit 6 connects with sampling pump 2, oil-water interface tool 4, heating rod 10 and drug feeding device 8,9 and three-way magnetic valve door 5, and computer control system 7 is connected with control circuit 6。
The operation principle of separator is as follows: crude oil enters after in separator 3, electrically heated rod 10 crude oil in separator 3 is heated, and temperature controls within best dehydration temperaturre scope；Drug feeding device 8 injects demulsifier by the best dehydration concentration of tested crude oil, and drug feeding device 9 injects degreaser according to the best oil removing concentration of tested crude oil；Through crude oil heating, add the crude oil separated after degreaser of demulsifier and moisture owing to density is different in separator 3 the upper and lower two-layer of formation, namely oil up swims to sink thus completing oil-water separation。
During use, the sampled pump 2 of crude oil of oil pipeline 1 sucks in oil water separator 3, is put back in oil pipeline 1 by three-way magnetic valve door 5 after the oil-water separation in crude oil。The sample rate of sampling pump 2 can be controlled by control circuit 6, controlled the open hour of two inputs of three-way magnetic valve door 5 by the feedback information (ball float of oil-water interface tool 4 position in oil water separator 3) of oil-water interface tool 4。Finally, the open hour ratio utilizing two inputs of three-way magnetic valve door 5 total can calculate water content in the crude oil transported in oil pipeline 1。The water content in crude oil that these information are sent in computer control system 7 to show in oil pipeline 1。
