The purpose of this utility model is achieved in that
The electric desalting of a kind of crude oil high speed, electro-dewatering equipment, comprise tank body, power supply, battery lead plate, the oil-feed divider, it is characterized in that: battery lead plate, centre are provided with the oil-feed divider, mixing valve, Hi-mixer are set on the oil inlet pipe, power supply is while output AC electricity and galvanic power of alterating and direct current, and battery lead plate connects power output end.
Its power supply is to divide three the tunnel behind transformer B; Output terminal is by the contact A 1 of transfer lever K2 ' wherein, by central contact O1, the connection electrode plate, it is two-way in addition, wherein one the tunnel through the K switch 1 even central contact O3 of transfer lever K2, divide two-way through contact A 3, B3, contact A 3 one tunnel connects transfer lever K2 through diode D1 " A2 connect battery lead plate through central contact O2; its B3 is leaded up to the B2 contact of transfer lever K2 and is connected battery lead plate; its another routing transformer B is through the direct-connected battery lead plate of K3, between its contact A 3 and the K2 by the B1 contact of diode D2 to transfer lever K2 '.
Its oil-feed divider is for being parallel to the imitative hammer body shape of battery lead plate.
The utility model power supply adopts high speed electric desalting electro-dewatering power source special, it is output AC electricity and positive and negative half-wave high voltage direct current simultaneously, design four layers of battery lead plate, form three DC electric field and alternating-electric field, wherein topmost an electric field forms high-strength electric field, horizontal oil-feed divider is sprayed onto emulsion in the electric field, guaranteed that promptly ejection has evenly rationally made full use of electric field again, mixing portion adopts the Hi-mixer form of connecting with mixing valve, make crude oil and washing water obtain thorough mixing, therefore, can improve desalination, dewatering efficiency greatly, and energy consumption reduces greatly also.
Below in conjunction with embodiment and accompanying drawing the utility model is explained in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 walks with voltage of supply to import synoptic diagram for alternating current-direct current.
Fig. 3 is the utility model oil-feed dispensing arrangement synoptic diagram.
Its structure of the utility model as Figure 1-3, the electric desalting of a kind of crude oil high speed, electro-dewatering equipment, comprise tank body 9, power supply 1, battery lead plate 2,3,4,5, oil-feed divider 6, it is characterized in that: battery lead plate 3,4,5, centre are provided with oil-feed divider 6, mixing valve 801, Hi-mixer 701 are set on the oil inlet pipe 8, and power supply 1 is while output AC electricity and galvanic power of alterating and direct current, and battery lead plate 2,3,4 connects power supplys 1 output terminal.
Its power supply 1 is to divide three the tunnel behind transformer B; Output terminal is by the contact A 1 of transfer lever K2 ' wherein, by central contact O1, connection electrode plate 3, it is two-way in addition, wherein one the tunnel through the K switch 1 even central contact O3 of transfer lever K2, divide two-way through contact A 3, B3, contact A 3 one tunnel connects transfer lever K2 through diode D1 " A2 connect battery lead plate 4 through central contact O2; its B3 is leaded up to the B2 contact of transfer lever K2 and is connected battery lead plate 4; its another routing transformer B is through the direct-connected battery lead plate 2 of K3, between its contact A 3 and the K2 by the B1 contact of diode D2 to transfer lever K2 '.
Its oil-feed divider 6 is for being parallel to the imitative hammer body shape of battery lead plate 3,4,5.
Its working process: crude oil is through Hi-mixer 701, mixing valve 801 becomes water solution of oil and evenly is sprayed onto by battery lead plate 3 by oil- feed divider 6,4, in 5 high-voltage electric fields of forming, under the effect of high voltage electric field force, little water droplets coalescence becomes big water droplet, rely on action of gravity, from oil phase, separate the bottom that is deposited to body 9, the crude oil that removes water moves upward, behind divider 6 place electric fields, enter by battery lead plate 2, the high-strength electric field that battery lead plate 3 is formed, at this moment, water droplet in the crude oil all is a fine liquid particles, settling velocity is very little, and be easy to be taken away by oily stream, have only and fine liquid particles is built up into big water droplet could from oil phase, spin off, and fine liquid particles is built up into big water droplet and just needed a higher electrical forces.The high-strength electric field that this is made up of battery lead plate 2, battery lead plate 3, provide enough big electrical forces to make fine liquid particles breakdown of emulsion, accumulation remaining in the crude oil, become big water droplet, settle down, this electric field structure has not only increased the residence time but also high-strength electric field coalescent, the sedimentation that more help fine liquid particles of crude oil in electric field, take off back crude oil water containing 0.2%, in addition lower.
High speed electric desalting electro-dewatering power source special 1 is the AC and DC power supply, as shown in Figure 2, be input to direct current and alternating-current on the pole plate simultaneously, form alternating-electric field and DC electric field, make full use of the effect of alternating-current and direct current to water droplet vibration, accumulation, this power source special, can change according to the electric conductivity of emulsion and regulate the voltage that outputs on the battery lead plate automatically, make energy utilization rationally in the accumulation of the breakdown of emulsion and the little water droplet of emulsion, energy consumption reduces greatly, only is 2/3rds of present high speed electric desalting equipment.
Because the raising of treatment capacity is had higher requirement to the thorough mixing of crude oil and washing water, have only thorough mixing could guarantee that salt fully contacts in fresh water and the oil, also could be dissolved in salt in the water fully, reach the purpose of dissolving salt, the utility model adopts Hi-mixer 701 form of connecting with mixing valve 801, not only enough energy are provided for crude oil and mixing of washing water, and at the mass transfer of salt and the fresh water proportion according to treatment capacity and crude oil on the time, the viscosity design, guaranteed that the salt in the crude oil washs in the fresh water, made and take off the technical indicator that the back salt content in crud oil is less than 3mg/l.
Facts have proved: its desalination of the utility model, dehydrating effect obviously improve, and take off back crude oil water containing only 0.2%, saliferous＜3mg/l, and energy consumption reduces by 1/3.
