Technical field
The utility model relates to the nitrogen oxide process field, especially relates to the system that adopts the modenite nitric oxide adsorption.
Background technology
Nitrogen oxide comprises multiple compounds, such as nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen trioxide, dinitrogen tetroxide and dinitrogen pentoxide etc.Except nitrogen dioxide, other nitrogen oxide are all extremely unstable, meet light, wet or thermal change becomes nitrogen dioxide and nitric oxide, and nitric oxide becomes again nitrogen dioxide.Therefore, what contact in the occupational environment is that several admixture of gas often are called the smoke of gunpowder (gas), is mainly nitric oxide and nitrogen dioxide, and take nitrogen dioxide as main.Nitrogen oxide all has toxicity in various degree, under the high-temp combustion condition, and NO
XMainly the form with NO exists, the NO of initial discharging
XMiddle NO accounts for 95%.But NO very easily reacts with airborne oxygen in atmosphere, generates NO
2So, NO in the atmosphere
XGenerally with NO
2Form exist.Airborne NO and NO
2By photochemical reaction, mutually transform and reach balance.Large or when having cloud and mist to exist in temperature, NO
2The the second important acid that further forms in the acid rain with the hydrone effect divides---nitric acid (HNO
3).When having catalyst to exist, as add suitable meteorological condition, N0
2The speed that is transformed into nitric acid is accelerated.Particularly work as NO
2With SO
2When existing simultaneously, mutually catalysis, the speed that forms nitric acid is faster, main applicable ammonia and nitrogen oxide generation chemical reaction neutralize nitrogen oxide in the industry, produce nitrogen and water after ammonia and the decompose nitrogen oxides reaction, but ammoniacal liquor volatilizees easily, cause secondary pollution, the adsorbent that the adsorption method for purifying nitrogen oxide is commonly used at present has molecular sieve, activated carbon, silica gel, mud coal etc., absorption method is because the adsorbent adsorption capacity is little, and the adsorbent use amount is large, and equipment is huge, regeneration period is long, and the efficient of absorption is low.
The utility model content
The purpose of this utility model has been to overcome the shortcoming and defect of above-mentioned prior art, and a kind of system that adopts the modenite nitric oxide adsorption is provided, and this system can move continuously, and the regeneration period is short, and adsorbent is reused, good absorbing effect.
The purpose of this utility model is achieved through the following technical solutions: the system that adopts the modenite nitric oxide adsorption, comprise the preprocessing system, adsorption-desorption system and the cooling gathering system that connect successively, described preprocessing system comprises blower fan, sour pump, cooling tower and wire gauzee filter; Wherein blower fan, cooling tower and wire gauzee filter link to each other successively, and sour pump links to each other with the bottom of cooling tower, and connect simultaneously blower fan on the pipe network of cooling tower, wire gauzee filter and adsorption-desorption system connectivity.The Main Function of wire gauzee filter is air-flow to be arranged evenly and with particle hold back.
Further, described adsorption-desorption system comprises absorber and the heater that is communicated with absorber, and absorber is communicated with wire gauzee filter and cooling gathering system simultaneously.
Further, described absorber comprises absorber one, absorber two, absorber three and absorber four, absorber one, absorber two, absorber three and absorber four all are communicated with heater, wire gauzee filter and cooling gathering system, and absorber one, absorber two, absorber three and absorber four lay respectively at the place, foursquare four angles centered by heater.The quantity of absorber is according to the needs of production setting, but at least will be set to four.
Further, described cooling gathering system comprises cooler, sour measuring tank and spinner flowmeter, and the three links to each other successively, and cooler is communicated with absorber one, absorber two, absorber three and absorber four simultaneously.
The acid measuring tank is used for measuring the quantity that absorber produces nitric acid, output for the accurate Calculation system is helpful, and spinner flowmeter claims spinner flowmeter, the device of flow is calculated in (position) that is located at the rotatable parts in the direct current pipeline by measurement, the handled easily personnel are to the control of flow, in the collection of subsequent operation to acid.
The nitric acid temperature that sucks out through the adsorption-desorption For Solutions of Systems is higher, must be cooled to 20 ℃ through cooling tower, collects behind sour measuring tank and spinner flowmeter.
In sum, the beneficial effects of the utility model are: this system and method thereof can be moved continuously, and adsorbent is the repetition regeneration, and the adsorbent use amount is little, and adsorption efficiency is high, recycles profitable.
