Description
The utility model is a kind of open side type catalysis electron exchange oxygen-eliminating device, belongs to boiler supply water deaerating equipment.
At present, normally used deaeration plant has two kinds: a kind of is distributing redoxite oxygen-eliminating device, and a kind of is combined type resene oxygen-eliminating device.Before a kind of oxygen-eliminating device floor space bigger, the life-span of the redoxite of back in a kind of oxygen-eliminating device is shorter, generally promptly need regenerate after 24 hours in work.
The purpose of this utility model is: design the catalysis electron exchange oxygen-eliminating device that a kind of floor space is little, life cycle is long, deaerating effect is good.
The utility model comprises the deaeration pump that has two oxygen scavenger layers, and there is the outlet pipe that communicates with its inside the lower end of deaeration pump, and there is water inlet pipe and the exhaust tank that communicates with its inside the upper end, and medicine-chest communicates with water inlet pipe.The oxygen scavenger layer that is positioned at deaeration pump top is an active carbon layer, and the oxygen scavenger layer of its below is the redoxite layer.There is a regenerating unit top of redoxite layer, and the regenerative system of the redoxite of forming by medicine-chest, Teat pipette and with the pipeline that both are connected joins through pipeline and regenerating unit.Between two oxygen scavenger layers, a porous plate is arranged.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.Wherein:
The A-exhaust tank, B-feed cock, C-deaeration pump, the D-active carbon layer, E-oxygen determination display instrument, F-porous plate, the G-regenerating unit, H-redoxite layer, I-quartz sand layer, the J-flowmeter, K-blender, L-flowmeter, the M-measuring pump, N-Teat pipette, O-medicine-chest, P-deoxygenation water tank, S, R-Pressure gauge, 1～16-valve.
The utility model is made up of medicine-chest (O) deaeration pump (C), pipeline and regenerative system.Be connected with an exhaust tank (A) and water inlet pipe mutually with the upper end of deaeration pump (C), have a feed cock (B) to be positioned at the termination of water inlet pipe in the deaeration pump (C), water inlet pipe is used for carrying demineralized water, hydrazine soup or regeneration soup in deaeration pump (C).Water inlet pipe communicates with the external world by the arm by valve (6) control.Be followed successively by active carbon layer (D) porous plate (F), regenerating unit (G), redoxite layer (H) and quartz sand layer (I) in the deaeration pump (C) from top to bottom.Wherein, porous plate (F) is a corrosion resistant plate, the double end drain cap all is installed, so that current are evenly distributed in each hole.There is an outlet pipe lower end of deaeration pump (C), and it communicates with the external world by the arm of valve (10) control.Medicine-chest (O) communicates with the water inlet pipe of deaeration pump (C).During deoxygenation, be the hydrazine soup in the medicine-chest (O).Regenerative system of the present utility model is made up of medicine-chest (O), Teat pipette (N), at this moment be redoxite regeneration soup in the medicine-chest (O), one agitator by driven by motor is arranged in the medicine-chest (O), its underpart links to each other with the external world by valve (14), pipeline passes through valve (13) to Teat pipette (N), link to each other with regenerating unit (G) in the deaeration pump (C) by valve (9), flowmeter (J), valve (I), the pipeline that connects regenerating unit (G) has one by valve (7) is controlled and the external world communicates arm again.When deoxygenation, hydrazine soup in the medicine-chest (O), by the valve (12) of medicine-chest (O) bottom, the pipeline through connecting measuring pump (M), valve (11), flowmeter (L), blender (K), valve (8), flowmeter (J), valve (2) links to each other with water inlet pipe.The water side of two flowmeters (J), (L) has a Pressure gauge (R), (S) respectively.The demineralized water that needs during deoxygenation enters blender (K) by pipeline, together enters deaeration pump (C) with the hydrazine soup.Enter deoxygenation water tank (P) through the demineralized water of the deoxygenation outlet pipe by deaeration pump (C) lower end through valve (5), (3).One arm is arranged through on the pipeline between valve (4) connection valve (5) and the flowmeter (J) between the valve (3) (5).The outer wall of the utility model deaeration pump (C) is fixed with the oxygen determination display instrument, and it is connected in respectively on the pipeline between the pipeline that links to each other with regenerating unit (F) and valve (3), (5) by valve.
Using before the utility model carries out the deoxygenation of demineralized water, at first will recoil and just wash, with the cleaning deaeration pump, and is standard to reach the Inlet and outlet water turbidity consistent.1, the recoil process on deaeration pump top: open valve (8), (1), (6) demineralized water through blender (K), flowmeter (J), enter and discharge by the water inlet pipe of its upper end by the middle part of deaeration pump (C).2, the process of just washing on deaeration pump top: open valve (8), (2), (7), make demineralized water enter and discharge by the water inlet pipe of deaeration pump (C) upper end by the middle part through blender (K), flowmeter (J).3, the recoil of deaeration pump bottom: open valve (8), (4), (5), (7), demineralized water is entered by the outlet pipe of deaeration pump (C) lower end, is discharged by its middle part.4, just washing of deaeration pump bottom: open valve (8), (1), (10), demineralized water is entered by deaeration pump (C) middle part, and is discharged by its lower end.
Oxygen removal process of the present utility model is finished like this: the hydrazine soup from medicine-chest (O) through valve (12), measuring pump (M), flowmeter (L) with demineralized water after blender (K) mixes, enter deaeration pump (C) by valve (8), flowmeter (J), valve (2) by feed cock (B) again, (D) carries out following reaction through catalysis at active carbon layer:
Finish thick deoxygenation thus.When further dropping to the redoxite layer, demineralized water carries out smart deoxygenation:
After twice deoxygenation, the dissolved oxygen of water outlet can be kept 2～4PPb, satisfies the needs of high pressure and superpressure boiler supply water deaerating fully.It is standby that deaerated water flow to deoxygenation water tank (P) by the outlet pipe outflow by deaeration pump (C) lower end through valve (5), (3).The N that two secondary responses produce
2Gas is collected by the exhaust tank of deaeration pump (C) upper end and is discharged.
Because the oxygen in the part demineralized water is removed in the thick deoxygenation of active carbon layer, thereby the consumption that is positioned at the redoxite layer of its below reduces relatively, makes its service life longer, just need regenerate in general 1 year.Open valve (13) with injecting regeneration in the medicine-chest (O) with soup during regeneration, soup enters regenerating unit (G) in the deaeration pump (C) through Teat pipette (N), valve (9), flowmeter (J), valve (1), and the back is discharged through valve (10) by the outlet pipe of deaeration pump (C) lower end in that redoxite is regenerated.
The utility model floor space is little, and deaerating effect is good, and has improved operating efficiency, is specially adapted to the water supply deoxygenation of high pressure, superpressure boiler.
