Abstract
The invention discloses an energy-saving pulverized coal production line system. The energy-saving pulverized coal production line system comprises a raw material bin, a rolling pulverizer and a finished product bin. The rear end of the procedure of the rolling pulverizer is further connected with a separating and powder selecting unit, rough pulverized coal separated out through the separating and powder selecting unit enters the raw material bin again, and fine pulverized coal separated out through the separating and powder selecting unit enters the finished product bin. Pulverized coal production with higher requirements is met through the technology combination of the efficient rolling pulverizer and an efficient powder selecting machine, and therefore the coal combustion efficiency is improved, and coal consumption is reduced.
Description
Technical field
The present invention relates to coal processing field, particularly to the production field of coal dust。
Background technology
As big developing country, China's energy demand in recent years is that rigidity increases, and resource environment constraint is strengthened increasingly, and resource utilization is low, energy supply and demand contradiction。Solve this contradiction, energy conservation priority can only be adhered to, reduce energy consumption, material consumption, advance energy resource structure diversification, adopt advanced energy generation technologies, increase the development strategy of energy supply。The consumption of current industrial energy accounts for the 70% of the whole energy-consuming of China, therefore carries out energy-saving and emission-reduction at industrial circle and China has particularly important meaning。
Existing coal dust manufacture field generally adopts the supporting cyclone separator of ball mill, and ball mill is to apply the most ripe in grinding industry, but is also simultaneously that efficiency is minimum。Conventional separators has an advantage in selecting the fine powder about 100 orders, but cannot meet the production of requirements at the higher level fine powder, as met the needs of production when selecting the fine powder of 200 orders。
Summary of the invention
The goal of the invention of the present invention is the deficiency in order to overcome above-mentioned background technology, it is provided that a kind of energy-saving pulverized coal line production system。
The technical scheme is that a kind of energy-saving pulverized coal line production system, it includes raw material cabin, roll-in flour mill and finished bin, described roll-in flour mill operation rear end is further connected with separation and selects powder unit, separated select the isolated rough coal grain weight of powder unit newly to access raw material cabin, separated select the isolated fine breeze of powder unit to enter finished bin。
Preferred technical scheme is: described separation selects powder unit to include the V-type powder concentrator connected with roll-in flour mill, the dynamic powder concentrator being terminated with after V-type powder concentrator operation。
Optimal technical scheme is: select powder cell processes rear end to be additionally provided with cleaner unit in described separation, enters finished bin after fine breeze removing dust device。
Beneficial effect: the coal dust that the present invention is implemented in combination in requirements at the higher level by the technology of efficient roll-in flour mill and dynamic powder concentrator produces, and obtains the fine coal powder of 200 orders, thus improving burning of coal efficiency, reduces coal consumption。
