6-nitro-1, 2-diazooxy-4-naphthalene sulfonate acidification material washing kettle tail gas purification device

Abstract

The invention discloses a 6-nitro-1, 2-diazooxy-4-naphthalene sulfonate acidification material washing kettle tail gas purification device. The device comprises an air inlet, the air inlet is connected to a buffer gas storage tank, the side of the buffer gas storage tank is provided with a gas collection fan and an air guide duct, the gas collection fan is installed at an inlet at the top of the air guide duct, the tail end of the air guide duct is respectively connected to a physical treatment chamber and a chemical treatment chamber, the physical treatment chamber comprises an activated carbon adsorption chamber and a water bath chamber, the activated carbon adsorption chamber comprises activated carbon carrying plates, the water bath chamber comprises a sprayer and a water splash board, the chemical treatment chamber comprises a spraying treatment chamber and a leaching treatment chamber, the leaching treatment chamber comprises a sprayer and a water splash board, the leaching treatment chamber comprises a water leaching chamber and a stirring rod, the physical treatment chamber and the chemical treatment chamber are provided with gas outlets and tail gas detectors are installed into the gas outlets. Through the buffer effects, timely pressure release, heat dissipation and heat gathering are realized and normal production is not influenced. Through the ingredient analysis, a treatment route is improved, reagent use is recued and a comprehensive cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to a device for purifying tail gas of a nitrate body acidification washing tank. Background technique [0002] Chemical production is the premise of people's production technology progress. Therefore, since the industrial revolution, various chemical factories have gradually become the most important national facilities in people's eyes, and the nitrate acidification industry is the top priority. However, In the actual production process of nitrate acidification, a large amount of seriously polluted waste gas will be produced. Today, with the increasing awareness of environmental protection, if this type of heavy industry does not carry out necessary tail gas treatment, it will inevitably cause serious social effects. However, due to this type of heavy industry The composition of exhaust gas is complex, including various nitrogen oxides and other compounds and solid parti...

[0002] Chemical production is the premise of people's production technology progress. Therefore, since the industrial revolution, various chemical factories have gradually become the most important national facilities in people's eyes, and the nitrate acidification industry is the top priority. However, In the actual production process of nitrate acidification, a large amount of seriously polluted waste gas will be produced. Today, with the increasing awareness of environmental protection, if this type of heavy industry does not carry out necessary tail gas treatment, it will inevitably cause serious social effects. However, due to this type of heavy industry Exhaust gas components are complex, including various nitrogen oxides and other compounds and solid particles, etc.

[0003] The traditional tail gas treatment methods mostly use activated carbon adsorption and water-soluble method to deal with this kind of tail gas, but this treatment method will increase the production cost on the one hand, and on the other hand, in the process of tail gas treatment, it will cause certain resistance to the discharge of tail gas , affecting normal industrial production, and even the phenomenon of backflow of tail gas
