Based on the technical scheme, the utility model consists of a sensor, a microcomputer control system, a stepping motor and a medicating device. The device has the advantages of a convenient and correct visual reading displayed by the LED which is controlled by the medicating device, a simple computer operation facilitating automation and without debugging after running, low energy consumption, a small volume, a precise computation, non-stop running and a good reliability of the instrument.
Description
The utility model relates to a kind of general control method, system and equipment, and is particularly a kind of for Water-In-Oil in the degrading crude oil or oil-in-water chemical dehydration computer control chemicals dosing plant.
Crude oil comes out from underground mining, is carrying a large amount of moisture content, and the water in these high water-content crude oils often exists with the form that suspended state mixes, and the moisture content that suspends is distributed in the crude oil with the graininess of " Water-In-Oil " and " oil-in-water ".If adopt the physics sedimentation, disengaging time is longer, inferior separating effect.So the dehydration job requirement before a sedimentation of well head, or is injected the separating effect that " demulsifier " improves oil, water in infall process of sealing pipeline course of conveying neutralization.For addressing this problem, the utility model has designed a kind of chemical dehydration computer control chemicals dosing plant, makes water-oil separating can reach all weather operations, good separating effect, and energy consumption is low, calculates accurately.
The utility model is to adopt such method to realize: chemical dehydration computer control chemicals dosing plant is in the process of injecting " demulsifier ", need carry out quantity control to " demulsifier " that is injected.If added " demulsifier " too much would not do not have oil, moisture from effect, influence crude oil yield and quality.According to this technical scheme, the utility model has adopted by sensor, Control System of Microcomputer, stepper motor and chemicals dosing plant and has been constituted.
Sensor is the total amount that the pulse signal that adopts flowmeter to send has directly reacted the oil water mixture that flows through in the pipeline, this pulse signal is delivered to a counter behind photoelectric isolating circuit, microcomputer is regularly inquired about counter, in case find that counter overflows then with counter zero clearing again, and in the internal storage of microcomputer, add up and multiply by the flow constant, just can get the flow number in this section period.Multiply by dosing according to this flow number and just can calculate the dosing amount than coefficient.Therefore can constantly add up outflow and add dose of microcomputer, simultaneously for dosing equably, microcomputer also calculates rotating speed at next one stepper motor in the identical time interval according to adding dose, thereby control step driven by motor dosing pump is blended in the dose that should add in the water equably, throws in the pipeline through high-pressure pump and mixes with oil water mixture.
The utility model compared with prior art has following characteristics:
1, the control chemicals dosing plant is accurate by LED intuitive display convenient reading.
2, computer operation is simple, is convenient to realize automation.
3, precision metering pump in the medicament-mixing device and high-pressure low-flow pump are two groups, in order to avoid break down, influence the ordinary production operation.
4, need not debug after the operation, energy consumption is low, and volume is little, calculates accurately, and all weather operations is turned round continuously, the instrument good stability.
Concrete structure of the present utility model and embodiment are provided by the following drawings.
Fig. 1 is a circuit block diagram of the present utility model.
Fig. 2 is a chemicals dosing plant general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are described further.
Embodiment
