Description
Technical field
The present invention relates to a kind of ammonia process synthesis magnesium hydroxide technical field, be specifically related to the ammonia in a kind of high efficiente callback waste gas
The ammonia absorption tower device of gas.
Background technology
Along with Environmental protection and safety in production require increasingly stringent, due in magnesium hydroxide technique wash water
Ammonia volatilization, in air, causes workshop condition severe, in order to avoid being directly discharged into air, effectively reduces the dirt to environment simultaneously
Dye, generally uses rectification method and vaporizing extract process to reclaim the ammonia in rich ammonia gas in industry.Rectification method is that steam is passed directly into rectification
In tower, evaporation is to reclaim ammonia, emits after steam condensation, causes subsequent biochemical to process technique burden and is significantly increased.Distillation process
Usually primary energy, technical process energy consumption is relatively big, adds production cost.Prior art reclaims the dress of the ammonia in waste gas
Putting, structure is complicated, and cost is high, and efficiency is low.
Summary of the invention
The problem that the present invention is to solve above-mentioned existence, it is provided that a kind of simple in construction, Ammonia recovery rate are high and low cost
Gas ammonia retracting device.
The present invention is by the following technical solutions: the ammonia absorption tower device of the ammonia in a kind of high efficiente callback waste gas, it is characterized in that
Be, the ammonia absorption tower device of the ammonia in described high efficiente callback waste gas, including ammonia absorption tower, mist eliminator, upper end endless tube, air-introduced machine,
Circulating pump and delivery pump；Described ammonia absorption tower bottom is provided with air-introduced machine, circulating pump, and mist eliminator is positioned at the top of upper end endless tube；On
Connecting endless tube shower nozzle on end ring pipe, endless tube shower nozzle packing layer downwards is sprayed water, and absorbing liquid is uniformly sprayed on filler.
Ammonia absorption tower tower body material is PPR, and pressure-bearing≤5kPa effectively reduces the cost of manufacture of ammonia absorption tower, magnesium hydroxide
Side product sodium chloride in technique, can bring in waste gas to be recycled, causes ammonia absorption tower corrosion failure, and PPR in addition to titanium alloy,
The optimal material of anti-chlorine ion corrosion.
Absorbing liquid delivers to ammonia absorption tower top through circulating pump, on sprinkler to filler, is evenly distributed on filler, selects
Filler mass transfer rate high, wettability is good, voidage is high, so that ammonia absorption tower absorbance is high, pressure drop is little；The efficient non-plugging selected
Shower nozzle, has the advantages that atomizing effect is notable, easy to adjust, it is ensured that the high degree of dispersion of liquid；Air-introduced machine extraction containing ammonia
Body from ammonia absorption tower bottom enter, through gas redistributor from bottom to top through packing layer, be fully contacted with liquid countercurrent, inhale
Receiving the ammonia in gas, then gas goes out ammonia absorption tower emptying after liquid isolated by demister；
Absorbing liquid, after gas isolated by the gas liquid high-efficiency separator of packing layer and packing layer bottom, is collected at the bottom of ammonia absorption tower
Portion, is then passed through circulating pump and delivers to top, so circulate, and constantly absorbs the ammonia in waste gas, until ammonia reaches rule in absorbing liquid
Fixed concentration, is sent to subsequent handling, supplements salt-free water simultaneously.
The invention has the beneficial effects as follows:
The ammonia absorption tower device of the ammonia in a kind of high efficiente callback waste gas provided by the present invention, cost is low, absorbing liquid cyclic absorption,
Ammonia density can reach 0.4mol/L, easy to operate, can be exclusively used in the recycling and administration of all kinds of ammonia-contaminated gas, reaches ammonia and recycles,
Effectively reduce production cost, energy-saving and emission-reduction, protection environment is played an important role.
