Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of mechanical descaling assembly, comprise heat exchanging body shell 1, described heat exchanging body shell 1 inside is divided into heat exchange heating region 28 and oil-polluted water decanting zone 29 by vertical dividing plate, described top, heat exchange heating region 28 is provided with heat conductive oil inlet 12, bottom is provided with conduction oil outlet 13, hot oil heater 9 is connected with between the heat conductive oil inlet 12 of described heat exchanging body shell 1 outside and conduction oil outlet 13, conduction oil output pump 11, motor-driven valve 10, by conduction oil output pump 11, the conduction oil in hot oil heater 9 is pumped in heat exchanging body shell 1, after 28 pairs, heat exchange heating region oil-polluted water heats, flow back to hot oil heater 9 by conduction oil outlet 13 circulate.
Described heat exchange heating region 28 is built-in with at least one mechanical descaling's body 17, varying in size according to treating capacity, and the quantity of mechanical descaling's body 17 can be multiple.Described mechanical descaling's body 17 comprises mechanical descaling's body case 2, mechanical descaling's body case 2 top is equipped with blind flange 14, blind flange 14 is fixed with Pressure gauge 15 and motor 5, and blind flange 14 also has steam vent 16, motor 5 bottom is connected with power transmission shaft 6 by decelerator, it is inner that power transmission shaft 5 is placed in mechanical descaling's body case 2, the periphery of power transmission shaft 6 is connected with several scale removal hairbrush 4, and the outer of scale removal hairbrush 4 contacts with mechanical descaling body case 2 inwall, power transmission shaft 6 is driven to rotate by motor 5, scale removal hairbrush 4 can be made to rotate around power transmission shaft 6, thus the dirt on mechanical descaling's body case 2 inwall is brushed away, avoid accumulation of mud.Described mechanical descaling's body case 2 is connected with oil-polluted water import 20 and communicating pipe 27, and the end of communicating pipe 27 is positioned at oil-polluted water decanting zone 29.When mechanical descaling's body 17 is more than one, several mechanical descaling's bodies 17 were connected by communicating pipe, were connected with hot oil heater 9 between the heat conductive oil inlet 12 of heat exchanging body shell 1 outside described in the communicating pipe 27 on last mechanical descaling's body 17 and conduction oil outlet 13.
Described oil-polluted water decanting zone 29 internal upper part is equipped with corrugated plating sedimentation and removes sand body 7, bottom is equipped with eddy flow and removes sand body 8, be divided into upper arm 31 in parallel and lower branch line 33 communicating pipe 27 in described oil-polluted water decanting zone 29, wherein go up arm 31 to be positioned at corrugated plating sedimentation and to remove sand body 7 top, lower branch line 33 is positioned at eddy flow and removes sand body 8 top, and upper arm 31 has oil-polluted water jet 32, oil-polluted water being ejected into corrugated plating sedimentation removes sand on body 7, the corrugated plating sedimentation body 7 that removes sand is made up of some pieces of corrugated platings, make the sewage be ejected on it carry out sedimentation to remove sand, silting can be avoided again on corrugated plating.Above-mentioned lower branch line 33 has lower oil-polluted water jet 34, oil-polluted water is ejected into eddy flow and removes sand the bottom of body 8 and heat exchanging body shell 1, avoid silting.Described lower branch line 33 is connected with the tangential pipe 30 of eddy flow liquid, body 8 inwall and the corresponding eddy flow in the end of the tangential pipe 30 of eddy flow liquid removes sand, making the liquid mixture with certain pressure enter eddy flow by pipeline cutting to mouth removes sand in body 8, liquid is used to produce eddy flow at entrance, and then in cylindrical cavity High Rotation Speed, produce very large centrifugal acceleration.Due to the density contrast of decentralized photo and continuous phase in the mixture of oil field, the centrifugal force causing two to obtain is different, the continuous phase centrifugal force that density is large is large, outwards move downward gradually, and export 25 by eddy flow sand discharge and discharge, and the little decentralized photo pressure of density is lower, heavy warp-wise axle center place moves, move upward, discharged by liquid outlet, thus realize the object of profit, silt two separation.
Be connected with sludge outlet 26 bottom described mechanical descaling's body 17, eddy flow removes sand bottom body 8 and is connected with eddy flow sand discharge outlet 25, and sludge outlet 26 and eddy flow sand discharge outlet 25 are all connected mud recovery pond 24 by mud discharge pipe 23.And heat exchanging body shell 1 top has enclosure exhaust hole 18, manhole 19, and be provided with safety valve 21, housing wall heat exchanging body shell 1 being positioned at one end, oil-polluted water decanting zone 29 has liquid outlet 22, treated sewage thus liquid outlet flows out.
This assembly is when production run, conduction oil in hot oil heater 9 delivers in heat exchanging body housing 1 by conduction oil output pump 11, and simultaneously the oil-polluted water medium of ternary composite driving block carries out mouth 20 by oil-polluted water and directly enters in mechanical descaling's body 17 and carry out intensification heat exchange.Oil-polluted water medium in mechanical descaling's body 17 and the abundant heat exchange of conduction oil outside mechanical descaling's body 17 heat up, for improving the programming rate of oil-polluted water, the body series connection of some groups of mechanical descalings can be adopted to use, oil-polluted water medium after intensification removes sand and to carry out buffering sedimentation and the eddy flow body 8 that removes sand by being transported to corrugated plating sedimentation communicating pipe 27 in body 7 and carry out eddy flow and remove sand, meanwhile, the silt in mechanical descaling's body 17 enters mud recovery pond 24 by sludge outlet 26 by the outer comb line 23 of silt.Discharged by sewage draining exit through wave-wave card sedimentation body 7 and the eddy flow silt settled down, colloidal substance and the heavy dirt etc. that body 8 processes that removes sand that removes sand, be transported in silt recovery pond by pipeline, process qualified after containing the oil-polluted water medium of silt, colloidal substance and heavy dirt, exported by external transport pipeline by liquid outlet 22.
This assembly adopts motor to drive scale removal, mechanical descaling's body domestic demand more exchange device hairbrush time, only need open the blind flange on equipment, power transmission shaft is extracted out, i.e. changeable hair brush, does not need equipment edible vegetable oil and cutting equipment housing of getting angry, simply easy to operate, scale removal hairbrush long service life, efficiency are high, can not produce potential safety hazard.This scale removal body features high scale-removing effect, equipment thermal conductivity factor is high, long service life, and maintenance of equipment expense is low.Silt after scale removal enters corrugated plating eddy flow and removes sand and to carry out secondary in body and to remove sand scale removal matter, thus ensures that oil-polluted water water quality reaches defeated standard outside oil field.
