Description
Technical field
This utility model relates to Gypsum Fibrosum production line field, particularly relates to the life of a kind of high-quality complex building Gypsum Fibrosum
Produce line.
Background technology
Power plant is qualified discharge sulfur dioxide, substantially uses wet desulphurization, but two water desulfurated plasters become again
New trade waste affects environment, and the whole nation has tens million of tons/year to increase to pile up, large-scale thermal power collection
The desulfurization the most in a wet process without exception of particularly five big electricity power groups of group produces a large amount of two water desulfurated plasters every year,
Its medium and small part provide Thistle board manufacturer as produce Thistle board raw material (about 30 yuan/
Ton)；Little part provides manufacture of cement producer to make cement retarder (about 25 yuan/ton) in the ratio interpolation of 3%,
The products such as remaining production minimal amount of plaster mould box, anti-static movable floor, gypsum putty, crystal whisker of gypsum (but
Because its production cost is compared with high and range is little, Gypsum Fibrosum utilization is the least), then can only pile up without what project utilized,
The remote power plant of the transportation range that is located in an outlying district the most all piles up (the most seriously by Gypsum Fibrosum and flyash
Dual disposal is piled up, and causes these two kinds of secondary resources forever can not effectively comprehensively utilize), it is dirty that Kingsoft is become
Dye source (polluting adjacent periphery environment second, more seriously rain drop erosion sulfur oxide is to subsurface wastewater infiltration system,
Serious polluted underground water resource).
Country pays much attention to protection environment；Protecting ecology, encourages exploitation secondary resource；Utilize industrial waste；
Require technological innovation；Energy-saving and emission-reduction, reduce energy resource consumption；Architectural industrialization is the most imperative.Chongqing municipal administration
Ye Yiyu mansion, mansion is done [2014] No. 176 files and is forwarded about the suggestion accelerating to advance building industry modernization, clearly
Propose by standardized designs, factorial praluction, prefabricated construction, integration finishing, information system management,
Improve construction quality, advance green construction, it is achieved energy-conservation.
Therefore, the problem that the existing mode of production exists:
1, fire coal is utilized to make heat source way: coal-fired serious environment pollution, national environmental protection department prohibites.
And owing to high temperature directly acts on the powder that particle diameter is thinner, this part Gypsum Fibrosum just becomes anhydrous gypsum, stone
Cream is big without watr-proportion, and plaster of Paris quality is inevitable bad.
2, natural gas is utilized to make heat source way: natural gas drying cost is the highest, and equally exists due to high temperature
Directly acting on the powder that particle diameter is thinner, this part Gypsum Fibrosum just becomes anhydrous gypsum, and Gypsum Fibrosum is without watr-proportion
Greatly, the inevitable bad problem of plaster of Paris quality.
3, power plant's residual steam is utilized to make heat source way: steam, as being dried, is calcined thermal source, is one i.e. warp
Ji, the heat exchange mode of environmental protection again, but the structure of steam dryer must be hollow axle, hollow blade, hollow
Urceolus, determine drying machine can not overload operation, Gypsum Fibrosum humidity bigger than normal will overload operation, cause and stop
(after overhauling to stop production two days after cooling, maintainer enters dryer inner will stick to hollow axle and sky to machine
The perching knife pointwise of desulfurated plaster on lobus cardiacus sheet is removed.After adhering to Gypsum Fibrosum removing, must again proofread drying machine
" static balance " and " dynamic balancing " of rotor, the safety of guarantee drying machine is properly functioning), and Gypsum Fibrosum is wet
Spend bigger than normal being difficult to avoid, owing to desulfurated plaster is the accessory substance of thermal power plant's generating, often outside desulfurated plaster
Portion's free water discharges higher than GB and design load, easily causes the accident that over loading is shut down.
4, extremely strong due to Gypsum Fibrosum adhesion, in the production process of dried gypsum, Gypsum Fibrosum sticks to above rotary shaft
And above blade, increase drying machine load (in design load scope)；Reduce dry heat transfer effect,
Directly result in energy consumption to increase；Production capacity reduces, and adheres to be gradually increased, and has a strong impact on the normal fortune of drying machine
OK.
5, the quality of plaster of Paris, in addition to the content of chemical composition, the percentage composition of its half aqueous phase and Gypsum Fibrosum
Granularity the normal consistency of product, comprcssive strength, rupture strength are had vital impact, existing
In all dry technologies, owing to the granularity of Gypsum Fibrosum is carse, medium and small state, and Gypsum Fibrosum is dried
Time and temperature are all identical, necessarily cause thin anhydrous of product cut size；What particle diameter was thick surpasses half water result,
The ratio of half water condition the most necessarily reduces.
6, the particle diameter at Gypsum Fibrosum processes in technique, grinds, owing to the humidity of Gypsum Fibrosum is the highest before drying machine
(outside attached water is more than 6%), grinds efficiency the lowest；If the plaster of Paris formed is ground,
Substantial amounts of half aqueous phase Gypsum Fibrosum can be heated and become without aqueous phase Gypsum Fibrosum, not reach the high quality results of Gypsum Fibrosum equally.
