Description
Technical field
The present invention relates to nitrogen oxide waste gas and diamond waste product comprehensive reutilization, more particularly to nitrogen oxide potassium nitrate
Reclaim the method and device of diamond.
Background technology
Diamond is naturally occurring most hard material in nature, is widely used in geological drilling and marble etc.
Cutting, grinding and drilling of hard brittle material etc. are processed.The rise of diamond industry, bring the swift and violent hair of processing of stone industry
Exhibition.China is diamond and diamond tool production and application big country, consumes substantial amounts of diamond every year, also produces substantial amounts of Buddha's warrior attendant
Stone waste product.In diamond waste product in addition to the diamond particles containing costliness, also there is very high recycling valency containing some
The material of value（Such as tungsten carbide, copper, cobalt, nickel）.Therefore, the recycling to diamond waste product is very significant.
During with clear water absorbing nitrogen oxide waste gas, to reach preferable assimilation effect, must just increase gas-liquid two-phase contact surface
Product, i.e., fully soak filler surface.This just makes clear water consumption big, and caused dust technology waste water is more, and discharge pressure is big.Existing work
Skill is will to flow to the dust technology at absorption tower bottom, with being pumped into tower top, cyclic absorption nitrogen oxide waste gas, and is constantly mended into circulation fluid
Fill the clear water of certain flow.This essence is to use acid waste water absorbing nitrogen oxide waste gas, its absorption driving force with clear water absorb compared with,
Substantially reduce.Current technology, which also has high-concentration dilute nitric acid discharge, influences environment and problem of resource waste.I utilizes existing work

Dissolution kettle supplements solid potassium chloride, and potassium nitrate product is taken out from low-temperature precipitation pond；Circulate and inhale in existing subsequent absorption tower absorbing liquid
During receiving nitrogen oxide, allow absorbing liquid to be contacted with diamond waste product, corrosion and absorption is either simultaneously or alternately carried out, corrosion produces
Nitrogen oxide also absorbed by existing absorption tower, during circulation by control supplement clear water flow, regulation corrosion kettle overflow
The corrosive liquid concentration of stream, the corrosive liquid for losing oxidisability are sent to and make the iron displacement subsequent treatment such as copper, regular replenishment diamond waste product,
Take out diamond particles.
A kind of device that diamond is reclaimed with nitrogen oxide potassium nitrate, it is by high-temperature digestion kettle, low-temperature precipitation pond, corrosion
The absorption tower of kettle and original technique forms, all built-in filler in A, B and C absorption tower, and A absorb the bottom of the tower side wall sets nitrogen oxide air inlet
Pipe, top set the tracheae between the AB towers of B absorb the bottom of the tower side wall connection, set and C absorb the bottom of the tower side walls at the top of B absorption towers
Tracheae between the BC towers of connection, C absorption towers top set offgas duct, and A absorption towers bottom surface sets A communicating pipes, A communicating pipe lower ends and height
Warm dissolution kettle top is communicated, and A fan inleting pipes are set at the top of high-temperature digestion kettle, and A blower fans escape pipe communicates with B absorb the bottom of the tower,
High-temperature digestion bottom portion sets A overflow pipes, and low-temperature precipitation pond is terminated under A overflow pipes, and the inlet tube of A pumps is inserted on low-temperature precipitation pond
Portion, outlet meet A and absorb tower top A shower nozzles；B, C absorption towers bottom surface sets B, C communicating pipe respectively, and corrosion is terminated under B, C communicating pipe
