Description
Technical Field
The invention relates to the technical field of yellow phosphorus slag recycling, in particular to a light aggregate building material produced by using yellow phosphorus slag and a production method thereof.
Background
The yellow phosphorus slag is waste slag generated in the production of industrial yellow phosphorus; 8-10 tons of yellow phosphorus waste residue is discharged when 1 ton of yellow phosphorus is produced. Because the yellow phosphorus slag contains a small amount of phosphate ions and fluorine ions, harmful substances in the yellow phosphorus slag after being washed by rainwater permeate into the environment and can threaten the ecological environment greatly. The problem that the phosphorus chemical enterprises need to solve urgently is to effectively improve the utilization efficiency of yellow phosphorus slag resources.
Meanwhile, the phosphogypsum is a byproduct generated in the process of extracting phosphoric acid (namely wet-process phosphoric acid) by decomposing phosphorite with sulfuric acid, and about 5 tons of phosphogypsum is generated by preparing 1 ton of phosphoric acid. The main component of the phosphogypsum is calcium sulfate dihydrate, and the content of the dihydrate gypsum in the phosphogypsum generally accounts for about 90 percent. In addition, the phosphogypsum contains a small amount of undecomposed phosphorite, fluorine compounds, acid insoluble substances, phosphoric acid solution and organic matters, and is acidic. The contents of heavy metals and radioactive elements in phosphate rock in China are low, so that the heavy metals and radioactive substances in the phosphogypsum are very low and are more than 10 times lower than those in the states of America, Morocco, Jordan and the like, and a good congenital foundation is created for the comprehensive utilization of the phosphogypsum in China.
At present, the core component of perlite, obsidian and pitchstone used for the expansion lightweight building materials is silicon dioxide with the content of more than 70 percent, so that the raw materials can have enough glass softening performance in the expansion process. The average content of silicon dioxide in the Guizhou yellow phosphorus slag is nearly 40%, which makes the expansion production of the light-weight building material from the yellow phosphorus slag possible, but compared with the common raw materials, the content of silicon dioxide in the yellow phosphorus slag is obviously lower, so that the light-weight building material produced from the yellow phosphorus slag and the production method thereof are provided to solve the problems.

In order to achieve the purpose, the invention adopts the following technical scheme:
a light aggregate building material produced by yellow phosphorus slag comprises the following raw material components in parts by weight: 10 parts of yellow phosphorus slag, 7 parts of silica sand, and 2-4% of water and 18-20% of phosphogypsum in percentage by mass.
Preferably, the water content of the yellow phosphorus slag and the silica sand is 2.3%, and the content of silicon dioxide in the silica sand is 85% -99%.
The invention also provides a production method of the light aggregate building material produced by using the yellow phosphorus slag, which comprises the following steps:
s1, selecting materials: grinding and screening the yellow phosphorus slag to ensure that the particle size of the yellow phosphorus slag is distributed between 40 and 50 meshes, and grinding the unqualified yellow phosphorus slag again until the yellow phosphorus slag is qualified;

s4, conveying the mixed materials to a high-temperature calcining furnace for calcining;
and S5, outputting the material after the calcination is finished, and naturally cooling.
Preferably, in the step S1, the grinding and screening process is performed by using a raymond mill and a multi-layer vibrating screen.
Preferably, the calcining temperature in the high-temperature calcining furnace in the S4 and the material and material inlet and outlet temperature are both 800-1200 ℃; calcining for 10-15 min.
The invention has the beneficial effects that:
1. the phosphogypsum is added into the formula of the yellow phosphorus slag and the silica sand, so that the influence on the stacking density of a finished product of the yellow phosphorus slag is small, and the method indicates that a proper amount of phosphogypsum can be added in the expansion process of the yellow phosphorus slag to realize the simultaneous expansion of the yellow phosphorus slag and the phosphogypsum and the purpose of dissolving the phosphogypsum, and is favorable for protecting the environment;
2. the content of silicon dioxide in the raw materials can be improved by matching the yellow phosphorus slag and the silica sand, so that the requirement of the content of the silicon dioxide required by the raw materials for producing the expanded light aggregate building materials is met, and the bulk density of a finished product is reduced;
in conclusion, the silica sand can be added to improve the content of silica in the raw materials, so that the requirement of the silica content required by the raw materials for producing the expanded light aggregate building materials is met, and the bulk density of the finished product is reduced. And the simultaneous expansion can be realized by adding the phosphogypsum, the aim of dissolving the phosphogypsum is realized, and the environment is protected.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. Referring to fig. 1, a light aggregate building material produced by yellow phosphorus slag comprises the following raw material components in parts by weight: 10 parts of yellow phosphorus slag, 7 parts of silica sand, and 2-4% of water and 18-20% of phosphogypsum in mass percentage, wherein the water content of the yellow phosphorus slag and the silica sand is 2.3%, and the silicon dioxide content in the silica sand is 85-99%. After material factors such as the mesh number of the phosphorus slag, the proportioning of ingredients (including phosphorus slag, silica sand, bentonite, a foaming agent and the like) and the like are controlled, the materials are put into a high-temperature calcining furnace for reaction, and reaction conditions such as feeding temperature, expansion time and the like are controlled at the same time, so that the bulk density of a finished product is obtained after the reaction is relatively evaluated. In the invention, the content of silicon dioxide in the raw material is increased by adding silica sand, so that the bulk density of the finished product can be effectively reduced; the expansion effect of the unground phosphorous slag is not as good as that of the ground phosphorous slag; the effect of directly expanding wet phosphorus slag is superior to that of directly expanding dry phosphorus slag; the test result also shows that the addition of the foaming agent, bentonite and fluxing agent can not effectively reduce the bulk density of the finished product; the granulation process can seriously affect the expansion effect of the phosphorous slag. When the addition amount of the phosphogypsum is 10 percent, the bulk density of a finished product is increased, but the increase is not large. However, as the mass fraction of phosphogypsum continues to increase to 18.7%, the bulk density of the finished product decreases, for example at 950 ℃, the bulk density of the finished product in the group with 18.7% phosphogypsum is reduced by about 7% compared with the bulk density of the finished product in the control group without phosphogypsum, which enables a lighter weight of finished product of the same volume and at the same time a good consumption of phosphogypsum.
Example 1:
s1, selecting materials: grinding and screening the yellow phosphorus slag to ensure that the particle size of the yellow phosphorus slag is distributed between 30 and 100 meshes;
s2, batching: the weight portions are as follows: 10 parts of yellow phosphorus slag, 7 parts of common silica sand and 18.7 percent of phosphogypsum, and on the basis, water with the mass fraction of 2 to 4 percent is additionally added;
s3, mixing and stirring: placing the materials in a crucible, and stirring the materials for 10-15min by a stirrer to fully mix the materials;
s4, conveying the mixed material to a high-temperature calcining furnace for calcining, wherein the expansion temperature and the material inlet and outlet temperature are both 1100 ℃; maintaining at expansion temperature for 12 min;
and S5, outputting the material after the calcination is finished, and naturally cooling.
The bulk density of the expanded product, determined after the reaction, was 450kg/m3。
Example 2:
s1, selecting materials: grinding and screening the yellow phosphorus slag to ensure that the particle size of the yellow phosphorus slag is distributed between 30 and 100 meshes;
s2, batching: the weight portions are as follows: 10 parts of yellow phosphorus slag, 7 parts of light silica sand and 18.7 percent of phosphogypsum, and on the basis, water with the mass fraction of 2 to 4 percent is additionally added;
s3, mixing and stirring: placing the materials in a crucible, and stirring the materials for 10-15min by a stirrer to fully mix the materials;
s4, conveying the mixed material to a high-temperature calcining furnace for calcining, wherein the expansion temperature and the material inlet and outlet temperature are both 950 ℃; maintaining at expansion temperature for 12 min;
and S5, outputting the material after the calcination is finished, and naturally cooling.
The bulk density of the expanded product, determined after the reaction, was 260kg/m3。
Example 3:
s1, selecting materials: grinding and screening the yellow phosphorus slag to ensure that the particle size of the yellow phosphorus slag is distributed between 40 and 50 meshes, grinding the unqualified yellow phosphorus slag again, and selecting a Raymond pulverizer and a multilayer vibrating screen for processing the yellow phosphorus slag until the yellow phosphorus slag is qualified, wherein the mesh number of the qualified yellow phosphorus slag is between 40 and 50 meshes, so that the yellow phosphorus slag is not required to be ground to be finer, thereby being beneficial to controlling the cost and improving the expansion effect. Research shows that when the particle size of the yellow phosphorus slag is larger than 40 meshes, the bulk density of a finished product shows a trend of increasing along with the increase of the particle size of the yellow phosphorus slag; the result is that when the particle size of the yellow phosphorus slag is less than 80 meshes, the bulk density of the finished product shows a tendency of increasing with the decrease of the particle size of the yellow phosphorus slag, which indicates that the yellow phosphorus slag is not ground to be finer as better in order to obtain better expansion effect;
s2, batching: the weight portions are as follows: 10 parts of yellow phosphorus slag and 7 parts of light silica sand, and on the basis, water with the mass fraction of 2-4% is additionally added;
s3, mixing and stirring: placing the materials in an inner crucible, and stirring for 10-15min by a stirrer to ensure that the materials are fully mixed;
s4, conveying the mixed material to a high-temperature calcining furnace for calcining, wherein the expansion temperature and the material inlet and outlet temperature are both 950 ℃; holding at the expansion temperature for 12 minutes; and S5, outputting the material after the calcination is finished, and naturally cooling.
The bulk density of the expanded finished product is 160-180kg/m3The bulk density of the high-quality light building materials on the market is already close to or reached.
