Description
technical field:
The invention belongs to technical field of phosphorous chemical industry, relate to a kind of phosphoric acid arsenic slag odor removal.
background technology:
The treatment process of arsenic sulfide slag is mainly divided into two kinds: pyrogenic process and wet method.Pyrogenic process, i.e. roasting method are the domestic methods reclaiming white arsenic and the most generally adopt from arsenic sulfide slag.Adopt oxidizing roasting, reducing roasting and vacuum baking etc. to process, arsenic directly reclaims with the form of white arsenic.The major equipment of pyrogenic process is air-flow stoving oven and reverberatory furnace, relies on that burning a large amount of fuel (as coal, coal gas, the heavy oil etc.) hot gas that produces carries out drying to arsenic sulfide slag, roasting obtains thick white arsenic, then distils with reverberatory furnace again and obtain pure white arsenic.Whole technological process power consumption is huge, and produces secondary pollution.The method process arsenic slag that namely wet method adopts acidleach, alkali leaching or salt to soak, first separates arsenic, and then reclaims arsenic product further or carry out harmless treatment from slag.This method have employed the treatment agents such as strong acid and strong base, and flow process is complicated, tediously long, not only introduces new impurity and causes secondary pollution, also greatly increases the processing cost of arsenic slag.
Given this, the present invention proposes that a kind of flow process is simple, energy consumption is low, high efficiency arsenic Slag treatment device, i.e. a kind of phosphoric acid arsenic slag odor removal.
summary of the invention:
Object of the present invention: be the economy in order to solve existing phosphoric acid arsenic Slag treatment method and technical problem, aim to provide that a kind of flow process is simple, energy consumption is low, high efficiency arsenic Slag treatment device, an i.e. phosphoric acid arsenic slag odor removal, improves the economic and social benefit of phosphoric acid production.
Technical scheme of the present invention is:
Utilize phosphoric acid enterprise self to produce the advantage of phosphoric acid, adopt excessive industrial phosphoric acid to remove the P of hydrogen sulfide in arsenic slag and remnants
2s
5, obtain the red arsenic product of higher degree while eliminating arsenic slag stink, the heat energy in reaction process and needed for red arsenic drying all from the by-product hot steam in phosphoric acid production, without the need to extra heat source.Do not introduce new impurity, non-secondary pollution on the one hand; Greatly reduce the energy consumption of arsenic Slag treatment on the other hand; In addition, the industrial phosphoric acid after embathing recycles or goes dearsenification reactor to carry out dearsenification, improves P
2s
5the service efficiency of dearsenic agent, reduces production cost, avoids secondary pollution.
The present invention is achieved in that
A kind of phosphoric acid arsenic slag odor removal, it is characterized in that: mainly arrange reactive tank, washing bath, filter I, filter II, agitator II, pump I, pump II, basin I, basin II and drying with steam equipment, the connection of this device is: reactive tank, pump I, filter I, washing bath, pump II, filter II connect successively.
The concrete connection of above-described pump I is: pump I inlet end, except being connected with reactive tank, is also connected with basin I, and the exit end of pump I, except being connected with filter I, is also connected with the acid inlet tube of reactive tank; Described basin I is separately connected with filter I.
