Abstract
The utility model discloses a flat-type phosphogypsum damming and grouting device which relates to the technical field of phosphogypsum stockpiling. The flat-type phosphogypsum damming and grouting device comprises a grouting pipe, wherein a grouting branch pipe is connected to the grouting pipe; grouting points are arranged on the grouting branch pipe; and discharge opening valves are arranged on the grouting points. According to the device, the grouting points are added on the basis of single-point grouting to implement multi-point grouting. After the device is used, the pollution of flying dust on an ambient environment is avoided; and moreover, a discharge water body is regulated to be in an acidic environment, the natural separation of coarse and fine gypsum is realized by virtue of secondary crystallization of the phosphogypsum in the acidic environment, the top of slag is uniformly lifted, each section is grouted according to damming requirements, a wet damming operation is performed, and the safety operation of a dam body is realized in a water catchment mode with multi-stage settlement. The flat-type phosphogypsum damming and grouting device opens a path for pilestocking of tailings produced in phosphoric acid production with wet process, and can create considerable economic benefits by saved damming materials per year.
Description
Technical field
The utility model relates to ardealite and stores up technical field, specifically a kind of flat type ardealite slurry-discharging equipment of building a dam.
Background technology
Rock phosphate in powder and sulfuric acid reaction are produced phosphoric acid and by-product ardealite, every production 1t P
2O
5Will produce the ardealite of about 5t.The amount that present ardealite can really be recycled also is not very large, and most countries stores away ardealite as a kind of dumps of wastes in the world.Since ardealite contain the pollutants such as phosphoric acid and fluorine, permeating the ground can polluted underground water, therefore, ardealite will properly be stored up.The mode of storing up of ardealite is classified by arrangement form, and burn sth to the ground type and mountain valley-type of ardealite place is close to the mountain type, cuts the river type.By the technological process classification, ardealite is stored up and can be divided into wet hydrofuge heap and the dried heap that drains.But which kind of mode all needs build a dam, build a dam and to draw material to build a dam outside the consumption in a large number, expensive effective stacking area and the safety of dam body poor stability of having dwindled greatly and greatly.Ardealite has highly dissoluble, and varies with temperature, and highly dissoluble makes seepage flow and evaporation cause gypsum corrosion and recrystallization, and gypsum has very strong bond, so ardealite can be used as dam material.But present slurry-discharging equipment is single-point discharging, and this structure can't realize the controllability of ardealite, water, can't realize that ardealite is gathered materials on the spot to build a dam.
The utility model content
Technical problem to be solved in the utility model provide a kind ofly take the mode of multiple spot plasma discharge to realize the controllability of phosphogypsum slag, water, cost is low, stability is high, the flat type ardealite that economizes the land resource is built a dam slurry-discharging equipment.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of flat type ardealite slurry-discharging equipment of building a dam comprises discharge pipe, connects the plasma discharge arm on the described discharge pipe, and the plasma discharge point is set on the described plasma discharge arm, the row's of setting mouth valve on the described plasma discharge point.
Described plasma discharge arm arranges the plasma discharge point every 100m.
Described plasma discharge arm is rectangle.
The utility model increases plasma discharge point and implements the multiple spot plasma discharge on the basis of single-point plasma discharge.The slurry-discharging equipment that is that a kind of cost is low, stability is high, flat type ardealite that economize the land resource is built a dam.Plasma discharge is artificially regulated in the utility model utilization, realizes the controllability of phosphogypsum slag, water.Utilize the secondary crystallization phenomenon of ardealite under sour environment, by adjusting the sour environment of production water quality, realize the natural separation of thickness gypsum, the location gypsum particle of building a dam is even, the even lifting of the top of the slag, each location is carried out plasma discharge according to the demand of building a dam and is regulated, and carry out the wet method operation of building a dam, and the charge for remittance mode of multi stage precipitation realizes the safety of dam body operation.After using the utility model, the one, avoided the pollution of dust from flying to surrounding enviroment, the 2nd, build mode and regulate discharging water body sour environment by wet, make dam body gypsum secondary crystallization, realize dam stability.For the tailings that produces in the Wet-process Phosphoric Acid Production process is provided by the approach that provides, the economic benefits that the annual dam material of just saving is created.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, a kind of flat type ardealite slurry-discharging equipment of building a dam comprises discharge pipe 1, connects plasma discharge arm 2 with threeway on discharge pipe 1, plasma discharge arm 2 be shaped as rectangle.Be provided with plasma discharge point 3 every 100m on the plasma discharge arm 2, at plasma discharge point 3 row's of installation mouthful valves 4.
During use, will enter discharge pipe 1 from the residual-slurry water of producing main device solid content 25%.On the basis of single-point plasma discharge, on discharge pipe 1, increase plasma discharge point 3 every 100m according to dam body length, implement the multiple spot plasma discharge.Slag slurry evenly enters Ba Qu, realizes the controllability of water, slag, and the even lifting of the top of the slag, is carried out plasma discharge and regulated in each location of inland dike according to the demand of building a dam, and the location gypsum particle of building a dam is even, builds a dam simple to operately to carry out according to plan in order.After using the utility model, the one, avoided the pollution of dust from flying to surrounding enviroment, the 2nd, by wet mode and the regulation and control construction water body sour environment built, make dam body gypsum secondary crystallization, realize dam stability.
Claims (3)
1. flat type ardealite slurry-discharging equipment of building a dam, comprise discharge pipe, it is characterized in that: the upper plasma discharge arm (2) that connects of described discharge pipe (1) arranges plasma discharge point (3), the row's of setting mouthful valve (4) on the described plasma discharge point (3) on the described plasma discharge arm (2).
