Abstract
The invention discloses a vacuum analysis deoxidizing device, mainly comprises a mixer, a deoxidizing horizontal tank, a pump, a filter, a deoxidizing nozzle and a vacuum pump system; the device is characterized that: a nitrogen producing device is placed before the mixer; the deoxidizing horizontal tank is built with fillers; the softened water is sent to the mixer; the nitrogen from the nitrogen producing device is absorbed by using the ejector action of the mixer and is mixed with water; the gas-water mixture is filtered by the filter, and the filtered water enters into the deoxidizing horizontal tank after first deoxygenization by the deoxidizing nozzle; the evaporated vapor, released oxygen and other gas are removed by the vacuum pump; the water is deoxidized twice after first deoxygenization by the filler; the processed deaerated water is supplied to the users. The invention has the advantages of improving the original deaerator by the nitrogen producing device, and executing twice deoxygenization to the softened water by the filler. The invention conquers the shortcomings of the original vacuum deoxidizing device and analysis deoxidizing device and reduces the operating vacuum degree of the vacuum deoxidizing device and improves the purity of the analysis gas.
Description
Technical field
The present invention relates to a kind of vacuum analysis deoxidizing device, utilize novel system nitrogen technology that original analysis deaerator and pure vacuum oxygen-eliminating device are improved.
Background technology
Resolve deoxygenation and utilize the Henry principle to come deoxygenation, promptly the partial pressure of this gas is directly proportional on the solubility of gas in water and the water surface: i.e. { O}=KP
0Partial pressure is more little, and the solubility of then this gas in water is more little.Therefore, reduce the partial pressure of oxygen, the solubility of oxygen is reduced.With after oxygen-free gas mixes strongly, because the partial pressure of oxygen approaches zero in the oxygen-free gas, oxygen soluble in water promptly can be separated from water because of the partial pressure of oxygen on the water surface is minimum, reaches the purpose of deoxygenation with oxygenated water.Existing analysis deaerator all needs a reactor, and the band carrier of oxygen that parses from water enters behind the reactor and the reaction of the active carbon in the reactor, and the oxygen and the active carbon reaction of separating in the gassing generate carbon dioxide.Therefore, do not had oxygen in the gas of reactor outlet, the gas of removing oxygen is used as separates gassing periodic duty once more, thereby reaches the purpose of removing oxygen.The heating of reactor has dual mode usually: it is in 500 ℃～600 ℃ the flue that first kind of mode reactor is placed in boiler cigarette temperature; Second way reactor add the thermal recovery electrical heating.Active carbon is housed in the reactor, and the oxygen reaction in the active carbon of heat and the gas of inflow reactor generates carbon dioxide.Its shortcoming is that deaerating effect is subjected to reaction temperature, condition effect such as active carbon institute water content, load variations and water temperature, hydraulic pressure.Simultaneously can only deoxygenation, can not remove other gases.Carbon dioxide content after the deoxygenation in the water increases, and the deaerated water pH value is reduced, and need add the alkali pH value to boiler feed water and regulate technology.Existing vacuum dust cather is subjected to load variations and water temperature, and condition effect such as hydraulic pressure, vacuum go out to suck the oxygen instability, and index is higher.And the vacuum dust cather long-play is at high vacuum state.
Summary of the invention
The present invention provides a kind of and utilizes novel system nitrogen technology that original analysis deaerator and pure vacuum oxygen-eliminating device have been carried out improved a kind of vacuum analysis deoxidizing device in order to overcome the shortcoming of original analysis deaerator.Used present advanced person's system nitrogen technology in resolving deaerating type of cycles, the nitrogen that directly utilizes nitrogen making machine to produce carries out deoxygenation, has cancelled the necessary reactor of conventional analysis deoxidizing device.Solve and understand gassing circulation repeatedly, need heating, the purity of separating gassing is not high, with the unfavorable technical problem of deaerating effect.
Technical scheme of the present invention is: a kind of vacuum analysis deoxidizing device, comprise blender, for sleeping in jar of deoxygenation, the water outlet water pump, stainless steel filter, the deoxygenation shower nozzle, filler, vacuum pump system, PLC automaton and corresponding process pipelines and control valve member, be characterized in that this device is equipped with nitrogen-making device before blender, be built-in with filler at deoxygenation jar for sleeping in, band presses demineralized water to deliver to blender, utilize the ejector action of blender to suck by the nitrogen that the nitrogen device comes, and mix with water and to form emulsion, filter through stainless steel filter by well-mixed air-water mixture, water after the filtration enters after the one-level deoxygenation in the deoxygenation jar for sleeping in by the deoxygenation shower nozzle, it is vaporific to form large tracts of land in jar, the effect of vacuum pump system, be in negative pressure state in jar, the balance of oxygen in water reduced and discharge the steam of evaporation and the carrier of oxygen of release, other gas CO
2, NH
3Extracted out by vavuum pump, water is after advancing the one-level deoxidation, and the filler by for sleeping in jar of deoxygenation carries out the secondary deoxidation then, and the deaerated water after the processing is supplied with the user by the water outlet water pump.
The beneficial effect of a kind of vacuum analysis deoxidizing device of the present invention is:
1. treat that deaerated water does not need The pre-heat treatment, therefore do not increase boiler room consumable vapour;
2. the deaeration plant occupation of land is few, and metal consumption is little, thereby reduces capital expenditure;
3. deaerating effect is good.Under the normal condition, the remaining oxygen content after the deoxygenation can drop to 0.05mg/L.
4. separating gassing does not need to circulate repeatedly, does not need heating, guarantees to understand the purity of gassing, has guaranteed deaerating effect simultaneously.
5. equipment is not to move under condition of high vacuum degree.
6. separate gassing and do not need extraneous thermal source heating.
7. when removing oxygen, can remove gases soluble in water such as carbon dioxide.
