Description
Technical field
The invention belongs to technical field of waste liquid treatment equipment, particularly relate to a kind of equipment utilizing waste liquid to produce calcium chloride.
Background technology
Losantin also claims chlorinated lime, is often applied to the bleaching process in Chemical Manufacture, due to its fast can onset and bleaching remarkably productive and occupy vital role in the industrial production.To be that calcium hydroxide and chlorine are counter generate Losantin to the reaction principle of Losantin, and with the generation of calcium chloride, react after follow-up separation of coming, a large amount of waste liquid can be produced, usually often produce 1 ton of Losantin and can produce 6 tons of waste liquids, the waste liquid main component produced is Losantin, calcium chloride is calcareous with other, and be dissolved with a certain amount of chlorine wherein, because Losantin and chlorine all have corrodibility, direct discharge can cause serious environmental pollution, by process Losantin waste liquid, Losantin can be converted into calcium chloride, 6 tons of waste liquids can reclaim the calcium chloride of preparation 2 ton 96%, there is huge economic benefit, and reduce the discharge fee of waste water, but at present not about the relevant device processed Losantin waste liquid.
Summary of the invention
For solving the problem, the invention provides a kind of equipment utilizing waste liquid to produce calcium chloride, comprise waste liquid reactor, the crown center of described waste liquid reactor is provided with stir shaft, the lower end of described stir shaft is connected with paddle, characterized by further comprising waste gas recovery still, pH detector, controller and injector, described waste gas recovery still is connected by pipeline with between injector, and described pipeline is provided with recycle pump; The probe of described pH detector is arranged in described waste liquid reactor; Described waste liquid reactor is provided with inlet pipe and vapor pipe; Described vapor pipe is connected with described waste gas recovery still; The side of described waste liquid reactor is provided with waste liquid feed-pipe, and top is provided with acid solution pipe, alkali liquor pipe, and bottom is provided with discharge nozzle; Described acid solution pipe, alkali liquor pipe and discharge nozzle are respectively equipped with acid solution motorized valve, alkali lye motorized valve and discharging motorized valve; Described alkali lye motorized valve, acid solution motorized valve are all connected with the output terminal of described controller with discharging motorized valve.
Also comprise liquid level sensor and feed-pipe motorized valve, described liquid level sensor is arranged in described waste liquid reactor, and is connected with the input terminus of described controller; Described feed-pipe motorized valve is arranged on described waste liquid feed-pipe, and described feed-pipe motorized valve is connected with described controller output end.
Beneficial effect of the present invention is: due to the chlorine produced in reaction process, by arranging vapor pipe by waste liquid reactor and waste gas recovery still UNICOM, the chlorine produced in waste liquid still is absorbed by the calcium hydroxide slip in waste gas recovery still, the recovery achieving chlorine uses, greatly reduce production cost, decrease environmental pollution; Adopt and arrange recycle pump between waste gas recovery still and injector, in the working cycle of slurries, make the top of waste gas recovery still form negative pressure, chlorine is inhaled into waste gas recovery still, and the slurries be recycled absorb; By arranging the motorized valve in pH detector, controller and each pipeline, realizing Mechanical course, making endpoint determination accurate, easy to operate; By arranging liquid level sensor in waste liquid reactor, control the liquid level in waste liquid reactor; The disposable Losantin that completes of the present invention is converted into calcium chloride, the absorption of chlorine and the adjustment of solution ph, directly generates the liquid calcium chloride of 33%, makes the contaminative of the liquid of discharge to environment less.
