Abstract
The invention discloses a device for gas recovery and desulfurization at a deamination tower top. The invention comprises a waste pipe I connected at the deamination tower top, a waste pipe II connected on a boiler, a water film dust catcher connected with the waste pipe I and the waste pipe II and a chimney discharging treated gases, wherein an exhaust pipe is connected between the water film dust catcher and the chimney. The invention has the advantages that the device has simple structure, easy production and low cost; and full contact and chemical reaction of dimethylamine and SO2 under a solution environment are used, thereby achieving the effect of simultaneous deamination and desulfurization and reducing discharge of the waste gases. The method is high effective and environment-friendly.
Description
Technical field
The present invention relates to the absorption treatment facility of DMF waste gas and boiler smoke, particularly a kind of device for gas recovery and desulfurization at deamination tower top.
Background technology
Can decompose generation dimethylamine and formic acid in the DMF heating process, flow process is long more, and heating-up temperature high de-agglomeration more is many more; Decomposition rate can be accelerated under the situation that has trace acid, alkali to exist, and formic acid has catalytic action to the decomposition of DMF, and the DMF decomposition rate increases with formic acid concn and the rising of temperature is the index increase; Decompose the formic acid that produces and take sub-fraction out of with the DMF finished product, major part is stayed tower bottoms or is discharged with residue, and the dimethylamine of corresponding generation is discharged with overhead water; Because the dimethylamine boiling point is extremely low, finally can be dispersed at normal temperatures in the air, dimethylamine is colourless inflammable gas or liquid; High concentration or when compressing and liquefying, it is smelly to have strong ammonia beastly, the stench that concentration has a fish like smell when extremely low; Inflammable, form explosive mixture with the air mixing energy, meet the danger that thermal source and naked light have combustion explosion; Contact fierce reaction with oxidant, gas is heavier than air, and can be diffused into place quite far away in the lower.
And contain more flue dust and a large amount of sour gas SO2 in the boiler exhaust gas; SO2 is a kind of colourless gas with intense stimulus property smell; Be prone to be dissolved in the blood and other stickiness liquid of human body, can cause certain harm to environment, can cause respiratory inflammation, bronchitis, pulmonary emphysema, eye conjunctivitis disease etc. if directly be discharged in the atmosphere; Teen-age immunity is reduced, and resistance against diseases dies down; SO2 can generate sulfate aerosol under the effect of oxidant, light, sulfate aerosol can make the people cause a disease, and increases the patient death rate.According to the research of OECD (OECD), when sulfate year, concentration was in the 10 μ g/m3 left and right sides, the concentration of every minimizing 10% can make the death rate reduce by 0.5%; SO2 can also stick with the floating dust in the atmosphere, when human body respiration, sucks the floating dust that has SO2, and the toxicity of SO2 is strengthened.Research shows, under the influence of the SO2 of high concentration, plant produces acute hazard, and blade surface produces necrotic plaque, or makes directly that plant leaf blade is withered to come off; Under the influence of low concentration SO 2, the GF of plant is affected, and causes output to descend, and quality degenerates; SO2 is to metal, and particularly to the corrosion of steel construction, bring very big loss to national economy every year, and according to estimates, the annual direct economic loss of bringing because of metal erosion of industrially developed country accounts for 2%～4% of total value of production in national economy.
Therefore how to take off amine and desulfurization processing effectively is the environmental issue of the required solution of manufacturing enterprise always, also is the social responsibility that manufacturing enterprise bore.
Summary of the invention
Problem to be solved by this invention just provides a kind of device for gas recovery and desulfurization at deamination tower top simple in structure, easy to make, with low cost, utilizes dimethylamine and SO
2Fully contact and the chemical reaction that takes place under solution environmental reach the effect of taking off the amine desulfurization simultaneously, reduce toxic emission, not only efficiently but also environmental protection.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: a kind of device for gas recovery and desulfurization at deamination tower top; It is characterized in that: comprise being connected the flue gas leading I that takes off the amine cat head, be connected the flue gas leading II on the boiler, the water dust scrubber that is connected with flue gas leading II with flue gas leading I; And the chimney of gas after the emission treatment, be connected with blast pipe between water dust scrubber and the chimney.
Further, said flue gas leading I and flue gas leading II merge into the top that the waste gas mixing tube is connected water dust scrubber.
Further, one of said blast pipe terminates at the bottom of water dust scrubber, and the other end of blast pipe is connected on the bottom of chimney.
Further, on blast pipe, be provided with air-introduced machine.
Further, be provided with the air blast of waste gas being sent into flue gas leading I taking off the amine cat head.
Further, be connected to air door before the said air blast.
After adopting technique scheme, the present invention has following advantage: simple in structure, easy to make, with low cost, utilize dimethylamine and SO
2Fully contact and the chemical reaction that takes place under solution environmental reach the effect of taking off the amine desulfurization simultaneously, reduce toxic emission, not only efficiently but also environmental protection.
