The waste gas treatment device disclosed by the invention is simple in structure and convenient to use; and by using the waste gas treatment device, by-products generated in waste gas treatment are changed, the resource consumption generated in waste gas treatment is reduced, the influence on environments is reduced, and the economic benefit arising from the ultrapure ammonia extraction process is improved.
Description
Technical field
The present invention relates to environmental protection industry (epi), is the corollary equipment in the ultra-pure ammonia extraction process, the emission-control equipment in particularly a kind of ultra-pure ammonia extraction process.
Background technology
Prepare in the process in existing ultra-pure ammonia, can produce the useless ammonia of more gas in the rectifying column, and the emission-control equipment great majority all are waste gas eluting column or aeration tower.The weak solution that these emission-control equipments all need use acidic materials such as sulfuric acid is as the spray agent, with in waste gas in ammonia, thereby reach standard to airborne release.In this course, need the acid and the water of labor, the accessory substance ammonium sulfate of generation also needs further to handle, and therefore, these emission-control equipments have not in the past caught up with strict day by day environmental protection and energy-conservation requirement.
Summary of the invention
Problem to be solved by this invention just provides the emission-control equipment in a kind of ultra-pure ammonia extraction process; Simple in structure; Easy to use, change the accessory substance that exhaust-gas treatment produces, reduce the resource consumption in the exhaust-gas treatment; Minimizing improves the economic benefit that the ultra-pure ammonia extraction process is brought to the influence of environment.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: the emission-control equipment in a kind of ultra-pure ammonia extraction process; It is characterized in that: comprise ammonia destruction furnace, hydrogen purifier and tail gas eluting column; The output of rectifying column overhead condenser is connected to ammonia destruction furnace, and ammonia destruction furnace output is connected to hydrogen purifier, and hydrogen purifier output is connected in the tail gas eluting column.
Further, the output of the top, rear end of said rectifying column overhead condenser is connected on the ammonia destruction furnace.
Further, the output of the furnace roof of said ammonia destruction furnace is connected to the hydrogen purifier front end.
Further, the output of the front top of said hydrogen purifier is connected in the tail gas eluting column.
Further, said hydrogen purifier is a palladium film purifier.
Further, the rear end of said hydrogen purifier also is connected to hydrogen-holder.The accessory substance ultra-pure hydrogen is stored utilization.
After adopting technique scheme, the present invention has following advantage: do not use acid solution can obtain helping the ultra-pure hydrogen product of the environment and the energy, all there is considerable influence environmental protection aspect and economic benefit aspect; Simultaneously all the other tail gas are environment to be pollution-free type light-component gas, can to pass through high altitude discharge, not only environmental protection but also simple.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is the structural representation of an embodiment of the present invention.
The specific embodiment
The structural representation of an embodiment of the present invention as shown in Figure 1; Emission-control equipment in a kind of ultra-pure ammonia extraction process; Comprise ammonia destruction furnace 1, hydrogen purifier 2 and tail gas eluting column 3; 41 outputs of rectifying column 4 overhead condensers are connected to ammonia destruction furnace, and ammonia destruction furnace output is connected to hydrogen purifier, and hydrogen purifier output is connected in the tail gas eluting column.In the present embodiment, the top, rear end of rectifying column overhead condenser output is connected on the ammonia destruction furnace, and uncooled gas in the condenser is transported in the ammonia destruction furnace, and the ammonia of remnants is decomposed into nitrogen and hydrogen; The furnace roof output of ammonia destruction furnace is connected to the hydrogen purifier front end, behind the hydrogen purifier purifying, obtains high-purity hydrogen; The front top output of hydrogen purifier is connected in the tail gas eluting column; Fail the gas through hydrogen purifier at the inlet end of hydrogen purifier; Be transported to and carry out drip washing in the tail gas eluting column; Thoroughly remove the ammonia of trace, make it not get into atmosphere, thereby realize zero emission intensity in the ultra-pure ammonia extraction process.
In the foregoing description, said hydrogen purifier is a palladium film purifier; The rear end of hydrogen purifier also is connected to hydrogen-holder 5, stores the accessory substance ultra-pure hydrogen and utilizes.
The present invention adopts ammonia destruction furnace that the light component impurity of rectifying column discharging is carried out the waste gas decomposition, and wherein most ammonia is decomposed into nitrogen and hydrogen, and catabolite is further purified through palladium film purifier, obtains the ultra-pure hydrogen product as byproduct; It is pollution-free type light-component gas that all the other tail gas are environment, can pass through high altitude discharge emptying.Ultra-pure hydrogen is a kind of energy resources of high-quality, is used widely in current society.Therefore, than the accessory substance ammonium sulfate of traditional eluting column device, no matter accessory substance ultra-pure hydrogen of the present invention is from the environment aspect, or the economic benefit aspect, all considerably beyond traditional emission-control equipment.
Except that above-mentioned preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of accompanying claims of the present invention.
