Abstract
A kind of cement producing line with material air separation, the air extractor duct that material gas is separated cover body (6) communicates with the inlet point of rotor weigher (2), the inlet point that feed opening and the material gas of Pulverized Coal Bin (1) are separated cover body (6) communicates, gas circuit arm (7) one end communicates with the air port that branches out of pipeline (4), and the other end communicates with branch's ventilation inlet of coal dust transfer line (5).The utility model has the advantages that: adopt one " material gas is separated cover body " to carry out alternative tremie pipe, make coal dust and gas that more spaces can be had to be separated.Then to original bypass air draft pipe changed course, the main air exhausting duct of access pulverized coal preparation, increases draft power.
Description
Technical field
The utility model relates to the accessory equipment field on cement producing line, is specifically related to a kind of cement producing line with material air separation.
Background technology
At present, in cement producing line production process, dore furnace coal feeding system fed distance reaches more than 100 rice, and rush coal phenomenon frequently, coal dust delivery pressure is on the low side and roots blower electric current unstable, causes feeding coal fluctuation greatly, poor stability.
Fineness of pulverized coal (90um tails over) is less than 8 ~ 12%, and moisture content is less than 1.5%, has fluidizability, extends the life-span of discharge head and anti-wearing liner; The coal dust viscosity of high moisture content is large, and after entering rotor, can produce very large resistance between rotor and closing plate card, rotor weigher is because of overcurrent stop jumping; Stop when kiln faces, in Pulverized Coal Bin, coal dust does not walk sky completely, and the delay resting period is long, occurs bonding, causes canopy storehouse; In calcination process, the size of fineness of pulverized coal also affects coal dust firing speed, so will carry out control in the link of pulverized coal preparation.
Pulverized Coal Bin does not descend the major cause of coal to be the impact being subject to air resistance.Roots blower is used for the airflow of Geldart-D particle upwards after rotor clearance, scurries into tremie pipe; Although be the air pressure balancing Pulverized Coal Bin and tremie pipe, the little dust collecting fan that tremie pipe at the bottom of storehouse leads to attic has been provided with bypass air draft pipe, and is connected with Pulverized Coal Bin upper end, discharges unnecessary gas; But the air draft pipe perpendicular throw be connected with tremie pipe reaches 12 meters, dusty gas cannot be taken away by the ability of blower fan, does not have the effect of equilibrium air pressure.
Summary of the invention
The purpose of this utility model is exactly for deficiency above-mentioned at present, and provides a kind of cement producing line with material air separation.
The utility model comprises the coal powder conveying system on cement producing line, coal powder conveying system mainly comprises Pulverized Coal Bin, rotor weigher and roots blower, the air outlet of roots blower is communicated with the ventilation inlet of rotor weigher by pipeline, it expects air separation in addition, material air separation comprises material gas and is separated cover body gentle road arm, material gas is separated covering on top and bottom is respectively equipped with inlet point, air extractor duct and discharging opening, material gas is separated cover body and is arranged on the rotor weigher of coal powder conveying system, and the material gas separation air extractor duct of cover body communicates with the inlet point of rotor weigher, the inlet point that feed opening and the material gas of Pulverized Coal Bin are separated cover body communicates, the air extractor duct that material gas is separated cover body is communicated with the main exhaust duct of coal mill by pipeline, pipeline is provided with and branches out air port, the coal dust transfer line of rotor weigher is provided with branch's ventilation inlet, gas circuit arm one end communicates with the air port that branches out of pipeline, the other end communicates with branch's ventilation inlet of coal dust transfer line, gas circuit arm is provided with electrically operated valve.
It is ellipsoidal configuration wide at the top and narrow at the bottom that its material gas is separated cover body.
The utility model has the advantages that: adopt one " material gas is separated cover body " to carry out alternative tremie pipe, make coal dust and gas that more spaces can be had to be separated.Then to original bypass air draft pipe changed course, the main air exhausting duct of access pulverized coal preparation, increases draft power.In the outlet of coal powder metering device, delivery duct is changed into " jet effect " shape being similar to " jet dredge pump ", its objective is the malleation reducing coal powder metering system outlet place, alleviate the pressure of this place lock wind and release.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is existing coal dust structure for conveying schematic diagram.
Detailed description of the invention
As shown in Figure 1, the utility model comprises the coal powder conveying system on cement producing line, coal powder conveying system mainly comprises Pulverized Coal Bin 1, rotor weigher 2 and roots blower 3, the air outlet of roots blower 3 is communicated by the ventilation inlet of pipeline 4 with rotor weigher 2, it expects air separation in addition, material air separation comprises material gas and is separated cover body 6 and gas circuit arm 7, material gas is separated cover body 6 top and bottom is respectively equipped with inlet point, air extractor duct and discharging opening, material gas is separated cover body 6 and is arranged on the rotor weigher 2 of coal powder conveying system, and the air extractor duct that material gas is separated cover body 6 communicates with the inlet point of rotor weigher 2, the inlet point that feed opening and the material gas of Pulverized Coal Bin 1 are separated cover body 6 communicates, the air extractor duct that material gas is separated cover body 6 is communicated with the main exhaust duct of coal mill by pipeline, pipeline 4 is provided with and branches out air port, the coal dust transfer line 5 of rotor weigher 2 is provided with branch's ventilation inlet, gas circuit arm 7 one end communicates with the air port that branches out of pipeline 4, the other end communicates with branch's ventilation inlet of coal dust transfer line 5, gas circuit arm 7 is provided with electrically operated valve.
It is ellipsoidal configuration wide at the top and narrow at the bottom that its material gas is separated cover body 6.
Material gas separation hood body running principle: adopt material gas to be separated the tremie pipe that cover body carrys out alternative former delivery system (see figure 2), make coal dust and gas that more spaces can be had to be separated.Then to original bypass air draft pipe changed course, the main air exhausting duct of access pulverized coal preparation, increases draft power.
Gas circuit arm principle of work: in the outlet of rotor weigher 2, (namely gas circuit arm 7 one end communicates with the air port that branches out of pipeline 4 delivery duct to be changed into " jet effect " shape being similar to " jet dredge pump ", the other end communicates with branch's ventilation inlet of coal dust transfer line 5), its objective is the malleation reducing rotor weigher 2 exit, alleviate the pressure of this place lock wind and release.
