The utility model consists of a softening pump, a sampling groove, a testing platform and a water inlet pipe for high pressure boiler, all of which are connected with a prying seat through a water supply pipeline; the utility model is also provided with two primary ion exchangers and two secondary ion exchangers as well as a salt pump and a salt box, and dissolves the difficulty of water processing of the coal-fired steam injection boiler in oilfield, leaving no calcium ion, magnesium ion and melting oxygen in boiler softening water after processing and achieving boiler water target with treatment of adding drug in softening water and residual hardware removal. Thereby, the utility model can improves service life of the coal-fired boiler and operation security and prevent pipe explosion, while reducing the cost of heavy oil production.
Description
Technical field:
The utility model relates to coal-fired steam-boiler water treatment facilities, the especially a kind of oil field Steam-injection Boiler Burning Pulverized Coal water treatment facilities annotated.
Background technology:
The steam flooding heavy crude producing is the main mode of oilfield exploitation viscous crude, at present, each uphole steam generator is a fuel with crude oil or natural gas all, increased the cost of winning of viscous crude so greatly, along with succeeding in developing of Steam-injection Boiler Burning Pulverized Coal, the fuel coal of injection boiler substitutes oil and natural gas, has reduced the cost of winning of viscous crude significantly.Because the change of fuel, very big change has all taken place in structure with to the requirement of water system in injection boiler, the demineralized water treating apparatus of former fuel oil steam injection boiler all can not satisfy the instructions for use of Steam-injection Boiler Burning Pulverized Coal aspect 26S Proteasome Structure and Function, all need to solve such as problems such as the processing of water quality and monitoring, automaticities, for this reason, a kind of oil field Steam-injection Boiler Burning Pulverized Coal water treatment facilities, what the application proposed just, this device is not reported through looking into.
The utility model content:
The utility model purpose is in order to overcome above-mentioned shortcoming, and a kind of oil field Steam-injection Boiler Burning Pulverized Coal water treatment facilities that provides, can provide qualified boiler demineralized water can prolonged boiler application life, prevent that pipe explosion accident from taking place.
Technical scheme:
For finishing the task that above-mentioned purpose proposes, the utility model is by forming by the softening water pump, sampling groove, chemical examination platform, the high-pressure boiler water inlet pipe that come water pipeline to connect above the sled seat; Be connected with two one-level ion-exchangers parallel with one another and two secondary ion-exchangers by pipeline between described softening water pump and the sampler, one at the secondary ion-exchanger is connected with salt pump, salt case by pipeline above the opening, and another opening communicates with the high-pressure boiler water inlet pipe by the chemical examination platform.
In demineralized water delivery side of pump termination one valve is arranged, this valve is connecting Teat pipette, medicine-chest with pipeline, and the stirring pump is housed in medicine-chest, communicates with high-pressure boiler water water inlet pipe by valve in the medicine-chest outlet.
Above the described sled seat air compressor, source of the gas control cabinet and instrument control panel are housed also.
The utility model working method:
Demineralized water during work in the water pipeline enters in the softening water pump, be input to again then in the ion-exchanger, in ion-exchanger by Na in the internal resin and the Ca in the water
2+, Mg
2+Ion-exchange can be removed Ca, Mg ion, thereby reaches the demineralized water effect.Demineralized water also can add NaSo by dosing tank under the stirring pumping action
3Solvent is removed oxygen in water, is reaching under the water supply index situation, enters in the high-pressure boiler to use for Steam-injection Boiler Burning Pulverized Coal again, reaches prolonged boiler purpose in application life.
The utility model compared with prior art has distinguishing feature:
Because this device is installed on the sled seat, it is rational in infrastructure, compact, and is convenient especially during transportation, and the water treatment facilities that is adopted is that ion-exchanger is made up of four standing vessels in addition; Two are one group and can singly organize operation, replace separately, make demineralized water in interchanger, fully carry out ion-exchange and with Ca, Mg ion remaval, dosing pump in the device again can be thorough with the softening oxygen in water in the medicine-chest in whole water treatment process, the clean removal, thereby can guarantee that burning boiler makes demineralized water can reach target water under the situation of water, ensures safe operation of the boiler in the open air.In addition, according to the boiler feed water characteristics, the assay platform that this device is provided with, sampling groove can be chemically examined and in time the residual harness water that exceeds standard carried out dosing and remove residual harness work again the water quality of outlet.
In order to improve the operating efficiency of this device, on the sled seat, also be provided with instrument board, a programmable controller (PLC) is arranged but the operation switching of implement device and the automation of the positive backwash work of pipeline in the dish.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure by 1, the sled seat, 2, softening water pump, 3, the one-level ion-exchanger, 4, secondary ion-exchanger, 5, instrument board, 6, the salt case, 7, medicine-chest, 8, Teat pipette, 9, salt pump, 10, stir pump, 11, the chemical examination platform, 12, the source of the gas control cabinet, 13, sampling groove, 14, high-pressure boiler water inlet pipe, 15, valve, 16, come water pipeline to form.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Among the figure, sled seat 1 long 8500mm, wide 3300mm, be that a metal material is made, the softening water pump 2 that is equipped with water pipeline 16 to connect above, this pump is the normal discharge pump, be connected to one-level ion-exchanger 3 with above the secondary ion-exchanger 4 that is in parallel with pipeline, described ion-exchanger is that four standing vessels are formed, wherein, two is one group of one group of running when work, another group is replaced, the use pneumatic control valve that surges carries out flow process control, two softening water pumps 2 are water supply installation after the demineralized waters in the water pipeline 16 are input in the ion-exchanger 3 in the future, make Ca in the demineralized water, the Mg ion is eliminated, to reach qualified demineralized water index, this demineralized water is taken a sample in pipeline enters sampling groove 13, on chemical examination platform 11, chemically examine then, qualified fully as water quality, then enter and be boiler water supply in the high-pressure boiler water inlet pipe 14, as defective through chemical examination water quality, then open this moment by salt case 6 with the salt device, salt pump 9, salt solution is injected into one, secondary ion-exchanger 3, in 4, Na ion exchange in the demineralized water is come out,, then can pass through medicine-chest 7 if think that through chemical examination the water of high-pressure boiler leaks hard phenomenon in addition, Teat pipette 8 and stir make a return journey residual harness in dewatering of pump 10, enter again in the high-pressure boiler water inlet pipe 14 after making demineralized water thoroughly reach target water at last, be boiler water supply.
The boiler demineralized water that enters has thus not only prolonged boiler application life, and can prevent that pipe explosion accident from taking place, and this device moves flexibly, and is easy to use, the Steam-injection Boiler Burning Pulverized Coal that should flow in the open air use.
