Description
One, technical field
The utility model belongs to chemical production equipment, relates in particular to a kind of airflow circulation control speed reaction unit of chloroazotic acid oxygen method dissolution of metals.
Two, background technology
China is diamond and diamond tool production and application big country, the diamond that annual consumption is a large amount of, also produces a large amount of diamond waste products.According to statistics, current industrial diamond has about 70% all for the manufacture of processing of stone instrument, and wherein diamond disc account for the overwhelming majority again.In use, in order to avoid damaging matrix, often open saw blade has the cutter head of about 10-20% not to be finished to diamond saw blade.In these useless saw blades, except containing except expensive diamond particles, some are also had to have the material (as wolfram varbide, copper, cobalt, nickel etc.) of very high recovery value.Adamantine recycling economizes on resources, the good project of benefiting the nation and the people.It is some self-employed workers that diamond reclaims colony, and their large multiplex chloroazotic acid or nitric acid dissolve metallic bond filters to obtain diamond particles.When chloroazotic acid or nitric acid dissolve metal, produce a large amount of reddish yellow NO gas balloonings, acid waste liquid is with rainwater cross flow, and cause mountain forest trees withered or died around, farmland cannot be cultivated.Along with the enhancing of law enforcement for environmental protection dynamics, confiscated by original fine, changing into puts on record now detains, and makes this diamond reclaim colony and loses living space.In the market, diamond waste material overstocks in a large number, and price slumps.How decontamination, making diamond reclaim industrialization is current very urgent important topic.
Three, summary of the invention
The purpose of this utility model is exactly to provide a kind of NO produced by chloroazotic acid (or nitric acid) dissolution of metals, becoming NO in a kettle. with dioxygen oxidation
2, directly absorbed by still liquid, and utilize kipp gas generator principle, the speed of the gases such as the NO that chloroazotic acid (or nitric acid) dissolution of metals is produced is by absorbing NO
2the factor restrictions such as speed, thus avoid NOx to overflow the airflow circulation control speed reaction unit of the chloroazotic acid oxygen method dissolution of metals of reaction system.
The technical scheme that the utility model adopts is: it is made up of reactor, air bag, blower fan and storage liquid still etc.Reactor has been set up a set of air current circulation, and this air current circulation is made up of air valve, air bag, gas circulation blower fan, frequency transformer, compressor flow variable valve, pipeline gentle flow point cloth sieve plate.Gas circulation blower fan is by Frequency Converter Control, its inlet pipeline is communicated with the tracheae of air bag with air valve with on reactor, and the pipeline of its exit end band compressor flow variable valve is connected with the air flow distribution tube of the side uniform pore openings below the air flow method sieve plate arranged bottom reactor.Reactor has also been set up a set of speed of response control device, this speed of response control device forms by storing liquid still, liquid seal trough, warning howler and pipeline, arrange bottom reactor with tapping valve with store the liquid discharge pipe be connected bottom liquid still, above storage liquid still, the liquid sealing pipe be connected with the liquid seal trough that warning howler is housed is set.Above reactor, kettle cover is other arranges charging valve, arranges the oxygen distribution pipe inserted at the bottom of still that to be connected with oxygen valve above side.
The utility model beneficial effect is: due on the basis of original chloroazotic acid or nitric acid dissolve Metal Production device, set up air current circulation, the NO that just can will produce in the process of nitric acid dissolve metal, is oxidized by oxygen into NO
2, NO
2send into after being absorbed by still liquid at the bottom of still, generate nitric acid and NO, decrease the consumption of nitric acid; And by setting up storage liquid still, make the speed of system dissolution of metals by absorbing NO
2the control of the factor such as speed, do not make NO
xto emerge reaction system, reach environment protecting.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Four, accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1 is air bag, 2 is blower fan, and 3 is compressor flow variable valve, and 4 is charging valve, 5 is kettle cover, and 6 is air valve, and 7 is warning howler, 8 is liquid seal trough, and 9 is liquid sealing pipe, and 10 is storage liquid still, 11 is air flow method sieve plate, and 12 is communicating pipe, and 13 is air flow distribution tube, 14 is tapping valve, and 15 is reactor, and 16 is oxygen distribution pipe, 17 is weigher, and 18 is oxygen valve, and 19 is frequency transformer.
Five, embodiment
As shown in Figure 1, reactor 15 has been set up a set of air current circulation, this air current circulation is made up of air valve 6, air bag 1, gas circulation blower fan 2, frequency transformer 19, compressor flow variable valve 3, pipeline and air distributor 13.Gas circulation blower fan 2 is controlled by frequency transformer 19, its inlet pipeline is communicated with the tracheae of air valve 6 with air bag 1 with on reactor 15, and its exit end pipeline of band compressor flow variable valve 3 is connected with the air flow distribution tube 13 of the side uniform pore openings below the air flow method sieve plate 11 arranged bottom reactor 15.Reactor 15 has also been set up a set of speed of response control device, this speed of response control device forms by storing liquid still 10, liquid seal trough 8, warning howler 7 and pipeline, arrange bottom reactor 15 with tapping valve 14 with store the liquid discharge pipe be connected bottom liquid still 10, above storage liquid still 10, the liquid sealing pipe be connected with the liquid seal trough 8 that warning howler 7 is housed is set.Above reactor, kettle cover is other arranges charging valve 4, arranges the oxygen distribution pipe 16 inserted at the bottom of still that to be connected with oxygen valve 18 above side.
When implementing the utility model, a certain amount of scrap metal is dropped in reactor 15, covers kettle cover 5, open charging valve 4, drip appropriate chloroazotic acid or nitric acid, reaction starts immediately, there is NO gas to release, open air valve 6 and compressor flow variable valve 3, start gas circulation blower fan 2.Open oxygen valve 18, slowly pass into oxygen, if gas redness is denseer in air bag, oxygen valve 18 can be turned down, if gas redness is lighter in air bag 1, oxygen valve 18 can be tuned up.Along with the carrying out of reaction, temperature raises gradually, and speed of response is constantly aggravated, and air bag 1 volume increases sharply.When air bag 1 volume be increased to maximum after, the gas that vigorous reaction produces makes reaction system pressure constantly increase, and chloroazotic acid or nitric acid is constantly pressed into storage liquid still 10, chloroazotic acid or nitric acid and scrap metal contact area are reduced, speed of response reduction.After chloroazotic acid or nitric acid consume in a large number, reaction weakens gradually, and temperature reduces gradually, and reaction system pressure also reduces gradually, and the chloroazotic acid or the nitric acid that are pressed into storage liquid still 10 slowly return reactor 15.After the chloroazotic acid or nitric acid front portion of storing liquid still 10 return reactor 15, air bag volume reduces gradually.When air bag volume-diminished obviously slows down or narrows down to below 1/5, under the aperture of air valve 6 can being transferred to the prerequisite of emerging without obvious red cigarette at liquid seal trough 9, warning howler 7 is kept to continue to report to the police, to get rid of rare gas element.When airbag gas is found time, close oxygen valve 18 and gas recirculation blower 2, open tapping valve 14, after still liquid is released, close tapping valve 14.Then, repeat aforesaid operations, until when scrap metal all dissolves in reactor 15, open kettle cover 5, cleaning reaction still 15.Process still liquid and scavenging solution, the materials such as the silicon carbide contained by recyclable scrap metal, tantalum, gold, copper.
