Description
Technical field
The present invention relates to the non-ferrous metal metallurgy technical field, more particularly, relate to a kind of hydrometallurgy sampler, but also be applicable to the collection of other industry liquid sampling.
Background technology
The fluid sampling device of prior art generally all needs auxiliary power: suction type (vacuum pump or vacuum system) fluid sampling device; Adding pressure type (air or inert gas) fluid sampling device; Pump (volume pump, in-line pump, ore slurry pump, liquid pump) formula fluid sampling device; The airtight continuous sampling system that is connected on chemical metallurgy production technology reactor or the pipeline is also arranged, complicated, easy obstruction is aging, the sample representation fluctuation is large, do not see and need not power, can from the report of drawing the simple and effective device that gathers the solution sample, use this sampling system device at strain smelting group straight soaking system and test arsenic salt Cobalt Purification nickel process exploitation for this reason.
The core process that purifies at coloured arsenic salt is composed in series by 5 reactors except cobalt nickel, and one of them is for subsequent use.By advancing except the adding arsenic salt solusion of the mixing tube before the cobalt nickel reactant device and electrolysis waste solution, then add suitable zinc powder at each reactor and remove cobalt, nickel with the electrode potential of control course of reaction.Because reaction is to carry out in the environment of acidity, electrode potential is more negative simultaneously, so might produce the arsine gas of severe toxicity in the reactor.For safe design, guaranteed to be in negative pressure state in each reactor by a cover exhausting and washing system, leak to avoid arsine gas.Need to every two hours get the interior sample of groove when normally producing and monitor the stablizing except cobalt nickel quality except cobalt nickel effect and assurance.The driving initial stage is adopted the bottom sampling except cobalt nickel, easily stops up and easily redissolves and have the problem such as potential safety hazard when taking a sample because the reactor underflow contains solid height, and this bottom sampling mode is eliminated.By contrast, adopt original DN80 hole for subsequent use simpler by hanging the sample loading mode sampling in reactor head, but sampling result is often higher.Specific practice is: utilize the hole for subsequent use flange of reactor head one DN80, connect a segment pipe and cause operating platform, the pipeline top fills a movable blind plate, and the blind plate rotation is just opened and can be hung sample with the stainless steel sample bucket.Practice through one or two years, there is following problem in this sample that manually hangs: 1) when sampling, when down winching to the reactor liquid level, sample bucket entered solution in the sample bucket, sample bucket is down also got the sample less than the middle part again, liquid level solution is owing to exist oxidation with contact with air, the result is often obviously higher, and is not representative.2) meeting accumulated slag and very difficult water rinse out in the sample bucket, accumulated slag is oxidized in air, can cause redissolution during lower sub-sampling, especially the 3rd, the 4th impurity content of reactor own is very low, because redissolving, accumulated slag cause the result of laboratory test of sample often than the high several times of real content, so that sampling result has lost meaning fully.3) when sampling has solution and accumulated slag and trickles down form crystallization near thief hole, pollutes the on-site sanitation environment.4) because thief hole only has 80mm, and sample bucket and chain often are stuck in the thief hole, be inconvenient to take a sample, and exist sample bucket to fall into the interior possibility of reactor.Be negative pressure when 5) normal in the reactor, if gas outlet stops up, the thief hole place then might have arsenic hydride and overflow, and has potential safety hazard.6) sampling spot is many, and sample time is long.
