Embodiment Construction

[0014] The vacuum analytical deaeration device includes a nitrogen generator 1, a mixer 2, a deaeration tank 5, an outlet water pump 7, a stainless steel filter 3, a deaeration nozzle 4, a filler 6, a vacuum pump system 8, an automatic control device and corresponding Process piping and control valves.

[0015] The demineralized water under pressure is sent to the mixer 2, and the nitrogen gas from the nitrogen device 1 is inhaled by the ejection of the mixer, and mixed with water to form an emulsion, and the fully mixed gas-water mixture is filtered through the stainless steel filter 3, and after filtration The water enters the deaeration tank 5 through the primary deaeration nozzle 4, forming a large area of ​​mist in the tank. Due to the action of the vacuum pump 8, the tank is in a negative pressure state, which reduces the balance of oxygen in water and releases it. The evaporated water vapor and released oxygen and other gases (such as CO 2 , NH 3 ) is drawn out by a v...

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 [0001] The invention relates to a vacuum analytical deaerator, which improves the original analytical deaerator and pure vacuum deaerator by using a novel nitrogen production technology. Background technique [0002] Analytical oxygen removal is based on Henry's principle, that is, the solubility of gas in water is proportional to the partial pressure of the gas on the water surface: {O}=K·P 0 . The lower the partial pressure, the lower the solubility of the gas in water. Therefore, reducing the partial pressure of oxygen can reduce the solubility of oxygen. After the oxygen-containing water is strongly mixed with the oxygen-free gas, since the partial pressure of oxygen in the oxygen-free gas is close to zero, the oxygen dissolved in the water will be separated from the water due to the extremely small partial pressure of oxygen on the water surface, reaching purpose of oxygen removal. The existing analytical deaerators all need a reactor, and the oxygen...
