Technical field
The invention belongs to coal tar special agent, more particularly to a kind of tar ammonia release agent.
Background technology
Ammonium hydroxide separator mainly undertakes the separation of coke-stove gas tar ammonia mixture after cooling.During due to being stopped
Between, in coke-stove gas carry secretly coal dust and emulsion etc. influence, the interface of ammonium hydroxide separator also produces fluctuation, Jiao is caused when serious
Oily water content is substantially increased, while makes to carry a large amount of tar in cyclic ammonia water secretly, influences the normal production of coke oven and tar device,
And influence the subsequent treatment of remained ammonia.
At present, coke-oven plant relies primarily on adjustment temperature, increase residence time and centrifugation etc. means improve tar matter
Amount and the separating effect for improving ammonia water and tar oil.The domestic situation for using chemical agent to improve tar ammonia separating effect is simultaneously few
See, but have begun to promote the use of this technology in Japan, North America and Europe.Chemical agent is added in process of production, is improved
The separation degree of tar ammonia, reduces tar viscosity, and the tar for so not only having achieveed the purpose that dehydration of tar but also having reduced in ammonium hydroxide contains
Amount, prevents deposition of the contained tar in system equipment in cyclic ammonia water.
Coal tar dehydrant in patent 201310619801.1 is by alkyl phenolic resin polyoxyethylene ether, phenol amine aldehyde tree
Fat Block polyoxyethylene polyethenoxy ether, methanol are re-dubbed.Since the patent is and the flash-point of methanol using methanol as solvent
For 12 DEG C, belong to harmful influence, therefore the dehydrating agent has the danger of burning and explosion in storage and transport.Meanwhile methanol has
Toxicity, easily produces human body harm, therefore the dehydrating agent is possible to that harm can be produced to staff when in use.And this patent
Using water as primary solvent, it is a kind of environment-friendly type medicament, is not belonging to harmful influence, safety, low toxicity.
Coal tar dehydrant in patent 201310330062.4 is re-dubbed by ether, methanol, sodium acetate, tap water.
Although using tap water as solvent in the patent, the content of methanol still accounts for mainly, thus the dehydrating agent equally have explosion and
Toxicity.It is a kind of environment-friendly type medicament and this patent is using water as primary solvent, is not belonging to harmful influence, safety, low toxicity.
A kind of tar ammonia release agent provided by the invention, is using water as primary solvent, is a kind of environment-friendly type medicament.Should
Medicament can reduce cyclic ammonia water oil content, improve the tar rate of recovery, ammonium hydroxide is more cleaned, substantially reduce heat exchanger and ammonia still process
Tar adhesion and cleaning frequency on tower surface；It can promote dehydration of tar, shorten the sedimentation time, save steam consumption, improve production
Efficiency；The COD contents of remained ammonia, distilled ammonia wastewater can be reduced, so as to mitigate follow-up biochemical wastewater treatment pressure；Lifting spray effect
Fruit, purifies primary cooler, effectively reduces the outlet temperature and thermic load of primary cooler；Can reduce tar viscosity, reduce tar pipeline,
Deposition and fouling at equipment, nozzle；Steam consumption can reduced or without using under the conditions of steam-heated, making tar is aqueous to reach
Mark；Equipment corrosion can be reduced, extends equipment life.
