Abstract
The present invention discloses a water-saving apparatus for water treatment of steam injection boiler water. The water-saving device comprises a water storage tank, a resin softening tank, a deaerator, and a steam injection boiler which are connected successively, wherein an outlet of the steam injection boiler is connected to a thermal recovery well mouth through a pipeline; the resin softening tank is connected to a sewage pond through a salt inlet pipeline and a substitution pipeline; and the resin softening tank is connected with water-saving equipment through a flushing pipeline. The water-saving equipment is mainly composed of a measuring instrument, a controlling equipment and a executive equipment which are connected successively, and the three instruments together constitute a single-circuit feedback control system. According to the present invention, by using the conductivity of regenerated outer drainage as the judgment standard, the conductivity instrument is used to perform real-time on-line detection on the regenerated outer drainage; and a monitoring signal is teletransmitted to a water treatment system and compared to the primary water, so that automatic recovery is achieved, andwastewater discharge amount is reduced.
Description
Technical field
The present invention relates to the water saving fixtures of water treatment regeneration link, especially injection boiler water-saving device for water treatment.
Background technology
The injection boiler water treatment system that oil-field thick-oil exploitation uses is divided into be run and regeneration two walks sequence greatly, and regeneration is divided into again backwash, enters salt, immersion, displacement, one-level are just washed, secondary is just washing 6 step sequences, namely divides 6 to walk sequences with clear water and completes cleaning to resin.After having regenerated, water treatment water outlet hardness number is zero.Because Hekou Area unboiled water hardness is higher, on average at 280mg/L-400mg/L, so injection boiler steam injection process sewerage disposing regeneration at present must carry out 1 guarantee water treatment operating performance every day.In current water treatment regenerative process, in each portion sort run time, sewage all enters pollution discharge pond and drains, wherein one-level is just washing the sewage just washing discharge with secondary has a larger part can reach unboiled water index, recycling can be carried out completely, and it all emits because isolating available water by existing technique, cause a large amount of wastes of water.Add a ton steam consumption water, reduce the economy that steam injection is produced.
Summary of the invention
The object of the present invention is to provide injection boiler water-saving device for water treatment, adopt regeneration outer row electrical conductivity of water as criterion, carry out real-time online with conductivitimeter and detect the outer draining water quality of regeneration, and monitor signal teletransmission water treatment controlling system and Yuan Shui are contrasted, thus realize the automatic recovery, reduce quantity of wastewater effluent.
In order to reach above-mentioned purpose, present invention employs following technical scheme, injection boiler water-saving device for water treatment, comprise the water tank, the resin that connect successively and soften tank, deoxygenator, injection boiler, described outlet of steam boiler is connected to thermal production well mouth by pipeline, described resin softens tank and also passes through to be connected to sewage lagoon into salt pipeline, displacement pipeline, and described resin softens tank and is also connected with water saving fixtures by flushing line.
Described water saving fixtures, primarily of the measuring apparatus be connected successively, control device, executive device three part composition, together constitute a single loop feedback control system.
Described measuring apparatus is formed primarily of a conductivitimeter and magnetic flow meter, and is all installed on resin and softens Real-Time Monitoring collection tank completing the outer drain discharge of regeneration and specific conductivity.
Described control device is PLC control system, and this Operation system setting has touch-screen and set(ting)value to judge comparison circuit, controls to perform partial act.
Described executive device is made up of the pneumavalve that two are in series, and one of them pneumavalve is connected to water tank by pipeline, and another pneumavalve is connected to sewage lagoon by pipeline, and described resin is softened tank and is connected between two pneumavalves by flushing line.
Compared to prior art, the present invention has following beneficial effect:
It is theory relation 1mg/L=2 μ S/cm based on hardness and specific conductivity that the present invention realizes the technical scheme that the automatic recovery adopts, and can know water hardness, thus whether judgement water quality meets recovery requirement by detecting water conductivity.When the defective i.e. specific conductivity of the water quality detected is higher than set(ting)value, I and II wash-down water is drained into sewage lagoon, when water quality is qualified, is automatically brought to reclaimer, and I and II wash-down water is recycled to water tank.Because water electric conductivity value to realize automatic collection, therefore by automatic acquisition testing electrical conductivity of water value, and be converted into control signal, after sewage conductivity value reaches clear water index, achieve the automatic recovery of qualified sewage.
The present invention increases recycle-water flow process, can part I and II rinses in reclaiming process sewage, and full process automatization, be not affected by human factors, efficiency is high, reclaims water quality guaranteed.

Embodiment
Detailed description for the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the present invention.
Conventional injection boiler Water flow-path, for soften tank 2, deoxygenator 3 from water tank 1, resin, inject thermal production well mouth 5 after injection boiler 4 is heat vaporized, enters the water that salt pipeline 8, displacement pipeline 9 and flushing line 7 discharge and all enters in pollution discharge pond 13 when resin softens the efficiency lost resin regeneration in tank.
As shown in Figure 1, injection boiler water-saving device for water treatment, has installed water saving fixtures 6 additional, primarily of measure portion, control section, execution part three part composition, which constitutes a single loop feedback control system.Measure portion is formed primarily of a conductivitimeter and a magnetic flow meter, completes the Real-Time Monitoring collection of the outer drain discharge of regeneration and specific conductivity; Control section is on the existing PLC control system basis of water treatment, and transformation circuit, revises reproducer, and the signal that realization monitoring gathers exports touch-screen to and energy and set(ting)value judgement are compared, and then controls to perform partial act; Execution part mainly contains two pneumavalves 11 and 12 and pipeline flow process forms.When the numerical value that measure portion conductivitimeter detects is higher than unboiled water conductance setpoint, pneumavalve 11 is opened, at this moment wash-down water with enter together with sewage that salt flow process 8 and replacement process 9 produce to be discharged into sewage lagoon 13, when I and II flushing electrical conductivity of water is less than or equal to unboiled water conductance setpoint, pneumavalve 12 is opened, at this moment the wash-down water meeting recovery standard is recycled in water tank 1, reuses.
The present invention is based on specific conductivity and hardness relation, detecting electrical conductivity of water can know water hardness.Because electrical conductivity of water can realize automatic detection, so by detecting sewage conductivity value in regenerative process, after sewage conductivity value reaches clear water index, the automatic recovery of sewage can be realized.By instant collection automatically, automatically detect the sewage that the water treatment of the automatic recovery injection boiler reaches unboiled water index, saving water resource, reduces steam injection cost.
The foregoing is only preferred embodiment of the present invention, be not used to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
