The specific embodiment
For ease of understanding the present invention clearly and completely, what at first describe below is the structure and the principle of work of relaying pressure device, and then the relaying pressure method is discussed.
Shown in the accompanying drawing 1 is the relaying pressurization of a relaying pressurization website, is called a pressurizing point in accompanying drawing 2.
Among Fig. 1, in delivery duct 1 upper shed, the connection in series-parallel induction pipe 2 of a solid-liquid separator 5 in parallel is formed the fluid passage by connection in series-parallel induction pipe 2 and solid-liquid separator 5.The method that the solidliquid mixture of delivery duct 1 is changed its course enter solid-liquid separator 5 from connection in series-parallel induction pipe 2 has multiple, and as on delivery duct 1 and connection in series-parallel induction pipe 2 flashboard being set respectively, the present invention is preferably at connection in series-parallel induction pipe 2 built-in two-way slide dampers 3.
The underflow outlet of solid-liquid separator 5 is connected in parallel on another opening part of delivery duct 1 again, makes the solidliquid mixture after concentrating fall into delivery duct 1, and the liquid part of separation connects water header tank 12 from top through outgate.The upper end of water header tank 12 is common chambers 7, and glassware 8 is driven in the connection rotation suitable for reading of common chamber 7, and the top that glassware 8 is driven in rotation connects elevated tank 9, and the liquid level of elevated tank 9 is controlled by the float-ball type liquid level valve.
The bottom of water header tank 12 connects several force (forcing) pumps 13, and the outlet of every force (forcing) pump 13 is parallel on the high pressure water house steward who has bypass valve 10 through one way stop peturn valve 11.For ease of force (forcing) pump 13 starting smoothly under negative pressure state, the counter flow pipe that a band flow regulating valve is set between its outlet and one way stop peturn valve 11 is connected to the top of water header tank 12, and this negative pressure discharge opeing technology can be provided by utility model ZL03272704.6 patent.
High pressure moisture two tunnel from high pressure water house steward discharge, one the tunnel is added on several pressure point of elevated tank 9, the solid shower nozzle 6 of several rows and several supercharging shower nozzles 4 formations, the supplementary copy section is carried the power waste in the way, and another route bypass valve 10 is told the part high pressure water and is added to and needs the position of pressurizeing beyond this pressurizing point.The high pressure water that is added to the solid shower nozzle 6 of plurality of rows can quicken to contain the solid speed of row and the kinetic energy of solid underflow.
The principle of work of relaying pressure device:
When 1, slide damper 3 was in the upper end, the import of solid-liquid separator 5 was dammed, and delivery duct 1 is normal fluid passage; When slide damper 3 is in midway location, the import of solid-liquid separator 5 and underflow export mixes fluid passage, delivery duct 1 also is the fluid passage; When slide damper 3 was in the lower end, delivery duct 1 was dammed and is changed its course, and solidliquid mixture enters solid-liquid separator 5 from connection in series-parallel induction pipe 2, and flowed back to delivery duct 1 again from the underflow outlet.At this moment, the relaying pressure device just is connected in series in the delivery duct 1, solidliquid mixture enters solid-liquid separator 5 from connection in series-parallel induction pipe 2 with tangential way, behind eddy flow immediately from the outlet of unique underflow be equal to contain solid concentration and flow flows back to delivery duct 1, solids wherein will be accelerated outflow because of the double action that is subjected to acceleration due to gravity and water (flow) direction, gas and tiny floating debris will on float to the top of common chamber 7, start rotation and drive glassware 8, the liquid of elevated tank 9 will carry out the equal-volume exchange with the gas of common chamber 7, behind common chamber 7 fulls of liquid, just become the exchange of liquid----liquid, at this moment rotation is driven 8 in glassware and is played dynamic sealing process, when a small amount of gas or floating debris enter common chamber 7, just can at any time it be discharged to elevated tank 9, thereby make solid-liquid separator 5 and water header tank 12 not contain gas or floating debris, got rid of the chaff interference that influences force (forcing) pump 13 operations.
2, when starting force (forcing) pump 13, the solidliquid mixture that enters solid-liquid separator 5 is divided into two parts, a part is the liquid part of overflow, because of equaling the overflow sectional area, maximum spillway discharge multiply by maximum overflow line speed, the overflow sectional area of setting will guarantee maximum overflow line speed at 20-50mm/s, to guarantee being deposited to underflow outlet discharge greater than the solids of 0.2mm.Spillway discharge is controlled by the discharge capacity of force (forcing) pump 13, and pressurized pump 13 sucking-offs of overflow water are added to the solid shower nozzle 6 of several rows and several supercharging shower nozzles 4 respectively after be divided into several behind pressurization and the adjusting pressure.To extremely strong propelling thrust is preceding arranged, can quicken the solid power of underflow row of solid-liquid separator 5 during the high pressure water ejection of the solid shower nozzle 6 of the row of being added to, to after suction force is arranged.The overflow water on solid-liquid separator 5 tops also is forced to suction in the suction journey of force (forcing) pump 13, these two suction forces descend the fluid pressure of solid-liquid separator 5 rapidly, even become negative pressure, and forming a kind of pulling force, the import of pulling solid-liquid separator 5 is accelerated flow velocity and is transmitted the pulling force that suction forms backward.High pressure water after force (forcing) pump 13 pressurization from several supercharging shower nozzles 4 further to the solidliquid mixture high-pressure injection of delivery duct 1, bigger forward thrust will be formed, though the big particle diameter solid in the solidliquid mixture can not enter force (forcing) pump 13, only increase kinetic energy and too kinetic energy is delivered in the solidliquid mixture with liquid.The liquid of current-carrying has reached the purpose that increases kinetic energy at relaying pressure device of the present invention.
3, the liquid flooding passage because of relaying pressure device of the present invention is with siphon mode work, and this just defines the imperial glassware 8 of rotation must be in actv. siphon scope.The feed liquor amount of force (forcing) pump 13 relies on the siphon mode feed flow fully, so the pressure of delivery duct 1 adds that this height of devices should not exceed the efficient range of siphon.
4, the pressure point of the form of nozzle of supercharging shower nozzle 4 and selection on delivery duct 1 all has alerting ability highly.Nozzle is generally selected the matured product of existing adaptation pipe pressurizing for use, as single mouth or ring discharge; Technological requirement is then depended in the selection at supercharging position, the front or the back, particularly the part high pressure water of telling from bypass valve 10 that can be placed on the fluid passage of solid-liquid separator 5 and connection in series-parallel induction pipe 2 formations are specifically designed in certain section delivery duct solidliquid mixture dilution pressurization or concentrated pressurization.
The application of relaying pressure method:
Among Fig. 2, the supercharging shower nozzle 4 of some pressurizing point 14,17,18 is arranged on the pressurization of this repeater station.When supercharging shower nozzle 4 is set on the delivery duct 1 as a pressurizing point 17,18 at leap some spots pressurizing point again, just form the plurality of network pressure point as 15,16, at this moment some pressurizing point just becomes the network pressurizing point as 19, and it regulates pressurization by bypass valve 10.Like this, among Fig. 2, from pressure point 15,16 to a pressurizing point 17,18 and network pressurizing point 19 constitute a pressurization net.Close bypass valve 10, high pressure water only is used for the pressure point of this pressurizing point, opens bypass valve 10, and high pressure water just can flow to the network pressure point 15,16 of pressurization net, realizes the network pressurization.
Long distance pipeline transport solid/liquid mixture is carried with general liquid and is compared, and except having the general character that general liquid carries, the key distinction is that liquid only makes carrier, main purpose is the conveying solid substance thing, be characterized in: 1, flow is big, the solid content height, and the solid granule size is inhomogeneous.2, pipeline is interspersed according to landform level, rising, decline, and the linear velocity on every section requires and solid content requires all to have specific characteristics.3, carry to want continuously, stable, the more important thing is and want economy, safety that this is mainly reflected in selects most economical solid concentration and the linear velocity of containing, because of square being directly proportional of droop loss and linear velocity, the solid content height, fluid density is big, viscosity is big, is the principal element that produces pressure drop.Therefore, the relaying pressure method is mainly reflected in big flow, high concentration, big particle diameter solidliquid mixture is carried on the treatment effect of the specific (special) requirements in the way.
To horizontal segment, it is generally higher to contain solid concentration, also is the pipe string of carrying proportion maximum in the way, even relatively because of the unit distance pressure drop, only requires the energy of the additional energy of relaying pressurization greater than the internal loss of our station scope, just can reach with a some pressurizing point mode.
To the ascent stage, require reduction to contain solid concentration, improve linear velocity.Ascent stage is the bottleneck position of carrying, the mode that can adopt a pressurizing point and network pressurizing point to combine.As Fig. 2, from pressure point 15,16 to a pressurizing point 17,18 and network pressurizing point 19 constitute an ascent stage pressurization net.The solidliquid mixture of sending here from horizontal segment point pressurizing point 14, diluted and improved linear velocity, reduced solid content to pressure point 15, also improve flow velocity once more to pressure point 16 further pressurization dilutions, to putting pressurizing point at 17,18 o'clock, hang down the pressurization of solid content under bigger flow, during to network pressurizing point 19, the liquid that is added to pressure point 15,16 by this station is separated again.Bypass valve 10 in accompanying drawing 1 i.e. purposes and establishing for this reason.The high pressure water of network pressurizing point 19 can be divided into two the tunnel, the one tunnel and be used in pressurization in this site-bound; One the road comes out from bypass valve 10 shunting, be used for the network pressurization, form leading pressurization, purpose is that dilution contains solid concentration, improves linear velocity, dividing streamflow because of this road is feedback quantity, what are shunted do not change and contain solid concentration and linear velocity beyond the network, change only be network with interior solid concentration and the linear velocity of containing.Ascent stage is related to the safe operation of whole piece travel line, can the economic transportation concentration and the flow that also are related to the whole piece travel line be realized, with the method that pressurization net internal feedback divides streamflow, specific (special) requirements between ascent stage and the whole piece travel line and the contradiction between the economical rationality standard have been solved.
In like manner,, also can adopt the hysteresis pressing mode,, add the potential energy of drop section, directly be added in the foot of descent stage from the high pressure water that bypass valve 10 is told in the bigger descent stage of drop.Solidliquid mixture is concentrated in descent stage has increased friction drag, but gravity that can the section of being lowered by in time replenishes, after having arrived the pipeline lowest part, add this kinetic energy again and add the high pressure water pressurization dilution of potential energy, make to contain solid concentration recovery normally, and obtain to quicken power the most timely, not only reduced the pipeline requirement of withstand voltage, improved safety, the voltage rise (potential energy) that can also make full use of descent stage provides conveying capacity for horizontal segment.This hysteresis pressurization does not change solid content and the flow beyond the network too, change only be that network is with interior fluid parameter.Therefore regulate bypass valve 10, just can obtain desirable conveying characteristic.
