Description

The injection boiler efficient water treatment device

One, technical field:

The utility model relates to a kind of water treatment device, particularly a kind of injection boiler efficient water treatment device.

Two, background technology:

Injection boiler is the single flow wet steam generator as the major equipment of viscous oil recovery, because the steam of its generation is wetting vapour, the moisture in the steam can be taken away salinity.Therefore, the technology of always continuing to use softening and deoxygenation in the requirement of water treatment guarantees its safe operation, and water treatment resin regeneration process can be divided into 5 stages, that is: backwash, advance salt, displacement, one-level and just washing with secondary and just wash.Therefore, produce softening water and just must waste certain former water, generally speaking, produce 1 ton of softening water and need 1.25 tons of former water, there is 0.25 ton of water to waste, deoxygenator is independent integrative-structure, because of water treatment device pressure of supply water instability in operation and regeneration, just must press the design of low pressure state in the design process of deoxygenator.In operational process,, make and the frequent open and close of deoxygenator inlet valve when closing, often cause building the pressure of water treatment water supply because of the continuous variation of service discharge, the one, cause the waste of electricity, also shortened the work-ing life of working shaft simultaneously.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of injection boiler efficient water treatment device that had not only economized on electricity simultaneously but also can improve the processing rate of water is provided.

Its technical scheme is: mainly be made up of water-softening plant and deoxygenator, water-softening plant comprises working shaft, primary softener, the secondary softening agent, salt pump, the salt pond, housing, dosing tank, working shaft connects primary softener successively, the secondary softening agent, blowdown apparatus, primary softener connects salt pump, the salt pond, blowdown apparatus connects deoxygenator, be provided with dosing tank between dirty device and the deoxygenator, water-softening plant is provided with housing, it is characterized in that: pressure transmitter is installed in the deoxygenator import additional, on the working shaft of water-softening plant frequency transformer is installed, electrical signal by pressure transmitter comes the control of conversion device, blowdown apparatus is installed the conductivitimeter of the exportable electrical signal of a cover, conductivitimeter connects the PLC controller, the PLC controller connects magnetic valve, pneumavalve, use the solenoid control pneumavalve, realize that by the switch of two-way pneumavalve clear water and the automatic of sewage separate.

Above-mentioned water-softening plant and deoxygenator integrate, and use the touch-screen control techniques, the whole demonstration on touch-screen and control.

The beneficial effects of the utility model are: use converter technique control working shaft, make and when the injection boiler underrun, reach purpose of energy saving, because the deoxygenator pressure of supply water is steady, make deaerating effect steady running, use the specific conductivity technology and make sewage separate automatically with clear water, recovery can utilize clear water, reach the purpose of water saving, the integrated control of Controlling System makes operating parameter more steady, use touch screen technology, make and control hommization more.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is water treatment structure sketches of the present utility model;

Among the last figure: working shaft 1, primary softener 2, secondary softening agent 3, salt pump 4, salt pond 5, pressure transmitter 6, deoxygenator 7, frequency transformer 8, conductivitimeter 9, blowdown apparatus 10, housing 11, dosing tank 12, magnetic valve 13, pneumavalve 14, PLC controller 15.

Five, embodiment:

1-2 in conjunction with the accompanying drawings, the utility model will be further described:

The utility model mainly is made up of water-softening plant and deoxygenator 7, water-softening plant comprises working shaft 1, primary softener 2, secondary softening agent 3, salt pump 4, salt pond 5, blowdown apparatus 10, housing 11, dosing tank 12, working shaft 1 connects primary softener 2 successively, secondary softening agent 3, blowdown apparatus 10, primary softener 2 connects salt pump 4, salt pond 5, blowdown apparatus 10 connects deoxygenator 7, be provided with dosing tank 12 between blowdown apparatus 10 and the deoxygenator 7, water-softening plant is provided with housing 11, pressure transmitter 6 is installed in deoxygenator 7 imports additional, frequency transformer 8 is installed on the working shaft 1 of water-softening plant, electrical signal by pressure transmitter 6 comes control of conversion device 8, blowdown apparatus 10 is installed the conductivitimeter 9 of the exportable electrical signal of a cover, conductivitimeter 9 connects PLC controller 15, PLC controller 15 connects magnetic valve 13, pneumavalve 14 realizes that by the switch of two-way pneumavalve 14 clear water and the automatic of sewage separate; Above-mentioned water-softening plant, Frequency Converter Control, deoxygenator, blowdown apparatus integrate, and use the touch-screen control techniques, the whole demonstration on touch-screen and control.

By converter technique, control the output rating of motor according to the setting of the setting of flow or pressure, can realize economizing on electricity 5%, reach the purpose of economize on electricity.Use in water conservancy, because backwash and just washing the water of second half section and belong to clear water in the water treatment reclaiming process, recycling fully, specific conductivity difference according to sewage, clear water, can realize the shunting of sewage and clear water by the control of specific conductivity, improving back 1 ton of softening water of production needs 1.15 tons of former water, reaches the purpose of water saving.
