Description
Technical field
The utility model relates to a kind of commodity flyash large-scale industrial production system.
Background technology
In recent years, because the continuous increase of coal-fired unit, the continuous expansion of thermal power plant's scale has caused the sharp increase of flyash discharge capacity.At present, coal-burning power plant's part takes the sorting mode to produce commodity flyash, and efficient is lower, and the cinder major part after the sorting produces secondary pollution again as waste discharge; Another part coal-burning power plant takes the explained hereafter commodity flyash of open-circuit grinding, but the quality of fly ash of producing is not high, cross that the grinding phenomenon is serious, power consumption is high, can not large-scale industrial production be the weak point of this technology in yielding poorly, grinding.Therefore, be badly in need of the technology of a kind of ability of exploitation large-scale industrial production commodity flyash.
Summary of the invention
The purpose of the utility model is exactly the deficiency to above-mentioned prior art, and the flyash large-scale industrial production system that a kind of technological process is simple, system's power consumption is low, output is high is provided.
The technical scheme that the utility model adopts is following:
A kind of flyash large-scale industrial production system; It is characterized in that it includes ball mill, elevator, grader and dust-precipitator; The former ash of power plant is at first sent into the charging aperture of said elevator, and the discharging opening of elevator connects the charging aperture of grader, and the cinder outlet of said grader connects the charging aperture of said ball mill; The discharging opening of ball mill is connected to the former grey charging aperture of elevator again, and the dusty gas air outlet of grader is connected to the air inlet of dust-precipitator.
The air outlet of said dust-precipitator is connected to the air inlet of high pressure positive blower.
The cinder exit of said grader is provided with lock wind discharge valve.
The air outlet tube mouth of said ball mill mill tail connects a wind inlet of said grader.
The beneficial effect of the utility model has:
Rational in infrastructure, technological process is simple, and system's power consumption is low, and production cost is low, and output is high, can satisfy the requirement of large-scale industrial production commodity flyash.The utility model coal-burning power plant's flyash of can 100% dissolving has promoted to have reduced the comprehensive utilization of resources of flyash the pollution of flyash to environment, thereby created good economic benefit and social benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
As shown in Figure 1, the utility model mainly includes ball mill 1, elevator 3, grader 4, deduster 7 and high pressure positive blower more than 9 parts and forms.The former ash of power plant is at first sent into the charging aperture of elevator 3; The discharging opening of elevator 3 connects the charging aperture of grader 4; The cinder outlet of grader 4 connects the charging aperture of ball mill 1; Grader 4 cinder exits also are provided with lock wind discharge valve 5, and the discharging opening of ball mill 1 is connected to the former grey charging aperture of elevator 3 again, and the dusty gas air outlet of grader 4 is connected to the air inlet of dust-precipitator 7 through expansion joint 6.The air outlet of said dust-precipitator 7 is connected to the air inlet of high pressure positive blower 9, and the discharging opening place of dust-precipitator 7 is provided with lock wind discharge valve 8.The air outlet tube mouth 10 of ball mill 1 mill tail connects a wind inlet 11 of said grader 4, and the exit of ball mill 1 is provided with lock wind discharge valve 2.
The course of work of the utility model is following:
The former ash of power plant is at first sent into elevator 3 and is fed into and carries out sorting in the grader 4; The finished product ash is collected through dust-precipitator 7 and is sent into warehouse for finished product; 1 fine grinding of cinder after sorting feeding ball mill, levigate ash is sent into elevator 3 again with former ash and is fed into grader 4 and carries out sorting, so periodic duty.Comprise part sorting ash and the levigate ash of part in the finished product ash that the utility model is produced, the sorting ash helps the reduction that finished product needs the water ratio, and levigate ash helps the raising of finished product activity index.
The integrated artistic of the utility model is half whole closed-circuit grinding system; It can reduce f-CaO content in the finished product ash, mainly be through flyash in mill in the fine grinding process, various particles are broken, levigate; Specific area increases; Particle surface energy increases, and under the environment of high temperature, f-CaO in the flyash and airborne vaporize water molecule produce clears up reaction in mill.But because material is insufficient with contacting of air in grinding in the existing open circuit mill, therefore the ratio of clearing up in mill is not high, so the effect of f-CaO content is limited in the open circuit mill reduction finished product ash.And half whole closed-circuit grinding system technology more helps the reduction of f-CaO content; Be dispersed in the hot-air field that contains quantities in grader inside mainly due to the flyash after the fine grinding (temperature is high); With this understanding, f-CaO generates Ca (OH) with adsorbed water molecule
2, improved the rate of clearing up greatly, improved the stability qualification rate of finished product ash.
The leading indicator of main process equipment that the utility model relates to and former ash and finished product ash is relatively shown in table 1 and table 2 (one of case):
Table 1: main process equipment
| Device name | Specification of equipment | Plant capacity (kW) |
| Ball mill | Φ 2.4 * 9m | 560.0 |
| Grader | DS (F)-1000 | 75.0 |
| Dust-precipitator | FGM96-2 * 5 | - |
| Centrifugal blower | 9-26 № 16D | 185.0 |
Adopt the grinding system of technology main process equipment in the table 1, under the high situation of former grey quality, grinding system power consumption≤18kWh/t, the leading indicator such as the table 2 of former ash and finished product ash,
Table 2: the leading indicator of former ash and finished product ash relatively
From table 2, can find out; The more former ash of need water of the levigate ash after more than half whole closed-circuit grinding systems are handled has reduced about 4 percentage points; Finished product ash fineness (45 μ m tail over)＜12%, finished product ash activity index＞70% reaches the specification requirement in the I level commodity flyash standard.
Other undeclared part that the utility model relates to is identical with prior art.
