Abstract
The utility model discloses a device of nitrogen oxide waste gas recovery diamond waste product, its characterized in that: replace the parallelly connected nitrogen oxide tail gas that absorbs of hydrologic cycle with cold nitrate saturated solution, contain sour ferric nitrate solution and replace the acidizing fluid to corrode bonding metals such as copper, iron, both solved rare nitric acid waste water that nitrogen oxide exhaust -gas treatment produced and retrieved the pollution problems such as waste liquid that the diamond produced, again the by -product ferric nitrate product.
Description
One, technical field
This utility model belongs to the recycling of the Chemical Manufacture three wastes, particularly with regard to the device of a kind of nitrogen oxide waste gas recovery diamond waste product.
Two, background technology
The second step nitration reaction of synthesis metronidazole and the nitric acid oxidation reaction preparing glyoxalic acid all release a large amount of nitrogen oxide waste gas, typically in multistage absorption device, and absorption of connecting step by step with water, produce a large amount of dust technology waste water, pollute environment.
Diamond is commonly called as " diamond ", is the allotrope of carbon.Diamond is material the hardest in the numerous naturally occurring materials found on earth at present.Graphite can form diamond under high temperature, high pressure.Diamond is mainly used in making cutting drilling tool.China is diamond and diamond tool production and application big country, annual consumes substantial amounts of diamond, also produces substantial amounts of diamond waste product.Diamond tool is, by the binding metal such as copper, ferrum, diamond particles is bonded to difform entirety securely.It is to be dissolved by the binding metal such as copper, ferrum acid liquid corrosion in diamond waste product that diamond reclaims, and filters to obtain diamond particles.After filtrate is reclaimed copper by current technology, directly discharge, environment is caused severe contamination.
Three, summary of the invention
Present invention aims to shortcoming present in existing nitrogen oxide exhaust-gas treatment and diamond recovery method, a kind of pollution that can solve nitrogen oxide waste gas and diamond recovery generation is provided, diamond can be reclaimed again, go back the device of the nitrogen oxide waste gas recovery diamond waste product of by-product ferric nitrate.
A kind of device of nitrogen oxide waste gas recovery diamond waste product, it is to be made up of multistage absorption tower, corrosion still, the displacement parts such as still and cooling bay, it is additionally arranged multistage absorption tower above corrosion still, every first grade absorption tower bottom is connected with corrosion still by return bend, arranging filler in absorption tower, top sets shower nozzle；The inlet tube of pump inserts below the liquid level of cooling bay, and the port of export is connected with the shower nozzle being arranged in absorption tower at different levels by conveyance conduit, converter be controlled pump, and delivery side of pump end conveyance conduit is provided above water inlet；Setting trachea above corrosion still to be connected bottom first order absorption tower, upper level absorption tower Xiang Duanshe trachea is connected bottom next stage absorption tower, and top, afterbody absorption tower sets exhaust emissions blower fan.Corrosion still and conversion still are all provided with heating jacket, heating jacket top sets the air inlet pipe of carrying vapour valve, bottom sets the outlet pipe of band condensation water valve, setting nitrogen oxide intake valve above corrosion still, lower end sets the discharge nozzle of band outlet valve, and corrosion still sets trachea with displacement still top and is connected, lower end sets the fluid pipeline of band still interstitial fluid valve and is connected, displacement still top sets air intlet, and middle part sets overflow pipe, and lower end sets the discharge nozzle of band outlet valve.
The invention has the beneficial effects as follows: owing to replacing water circulation absorbing nitrogen oxide tail gas in parallel with cold nitrate saturated solution, the binding metals such as acid liquid corrosion copper, ferrum are replaced containing acid+nitric acid ferrous solution, both solved dust technology waste water that nitrogen oxide exhaust-gas treatment produces and reclaimed the pollution problem such as waste liquid that diamond produces, again by-product ferric nitrate product.
The utility model is described in further detail below in conjunction with the accompanying drawings:
