Description
Technical field
The utility model 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 purpose of this utility model 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, the utility model have employed 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 utility model has following beneficial effect:
It is theory relation 1mg/L=2 μ S/cm based on hardness and specific conductivity that the utility model 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 utility model 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.
Accompanying drawing explanation
Fig. 1 is the structure iron of injection boiler water-saving device for water treatment of the present utility model.
In figure: 1-water tank; 2-resin softens tank; 3-deoxygenator; 4-injection boiler; 5-thermal production well mouth; 6-water saving fixtures; 7-flushing line; 8-enter salt pipeline; 9-displacement pipeline; 11, pneumavalve; 12, pneumavalve; 13, sewage lagoon.
Embodiment
Relevant detailed description of the present utility model 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 utility model.
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 utility model is based on specific conductivity and hardness relation, and 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 utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
