Abstract
The utility model discloses a pulverized coal preparation system, which comprises a pulverizing mill and a pulverized coal separation mechanism for separating the grinding materials in the pulverizing mill; wherein the upper end of the pulverized coal separation mechanism is connected with a draft fan mechanism by a dust removing device. The pulverized coal preparation system is improved in that the pulverized coal separation mechanism comprises a coarse pulverized coal separator and a fine pulverized coal separator which is connected with the coarse pulverized coal separator; the coarse pulverized coal separator is connected with the pulverizing mill; the lower end of the fine pulverized coal separator is connected with a vibration feeder; the upper end of the fine pulverized coal separator is connected with the dust remover; the top of the dust remover is connected with the draft fan; the lower end of the fine pulverized coal separator is connected with the vibration feeder which transports the fine pulverized coal to a fine pulverized coal bin; and the lower part of the fine pulverized coal bin is connected with a single bin pump used for weighing and storing the fine pulverized coal. The pulverized coal preparation system adopts secondary separation for the pulverized coal, so that the production efficiency is significantly improved, and the dust content in exhaust emission is obviously reduced.
Description
Technical field
The utility model relates to a kind of coal dust preparation system.
Background technology
Traditional fuel pulverizing plant, coal cinder is by feeding coal equipment feeding flour mill, and the coal dust after the oven dry separates by the coal dust separating mechanism, and meal is got back in the flour mill grinding again, fine powder after the separation is collected as finished product through deduster, and the cleaning gas after the separation discharges by blower fan.In this fuel pulverizing plant, because coal dust its disengagement weak effect, the meal quantity that turns back in the flour mill is bigger on the one hand, causes system's production efficiency low; On the other hand, the whole fine powders after the separation are all collected through deduster and are obtained finished product, cause the operating pressure of deduster big first, reduce deduster service life, make that second to enter in the tail gas in the atmosphere Dust Capacity via air-introduced machine bigger, cause environmental pollution.
The utility model content
The purpose of this utility model will provide a kind of new coal powder preparation system exactly, to enhance productivity, reduces environmental pollution.
The utility model is achieved in that this pulverized coal preparation induction system, comprise flour mill, be used for coal dust separating mechanism the grinding material separation of flour mill, coal dust separating mechanism upper end joins by dust arrester and air inducing mechanism, its improvements are that described coal dust separating mechanism is made up of mill separator and the pulverized-coal collector that joins with it, mill separator and flour mill join, and the lower end and the oscillating feeder of pulverized-coal collector join; The upper end and the deduster of pulverized-coal collector join, and dust remover roof and air-introduced machine join, and the pulverized-coal collector lower end is connected to the oscillating feeder that fine breeze is outputed to the fine powder storehouse, and bottom, fine powder storehouse is connected to the single storehouse pump that is used for weighing, stores fine breeze.
In the utility model, the coal dust separating mechanism is made up of mill separator and the pulverized-coal collector that joins with it, coal dust separates through mill separator, isolated meal is got back to flour mill and is carried out secondary grinding, fine powder enters pulverized-coal collector to be separated once more, isolated fine powder directly enters the fine powder storehouse, and superfine powder also enters the fine coal storehouse after collecting through deduster, clean gas discharging.Because adopt secondary to separate, separative efficiency improves, the coal dust quantity of returning flour mill obviously reduces, thus the production efficiency of significantly improving.Owing to installed pulverized-coal collector additional, make the fine powder major part after the separation directly enter the fine powder storehouse, thereby alleviated the operating pressure of deduster greatly, increased deduster service life; On the other hand, also obviously reduced the dust content in the exhaust emissions.

Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further
Shown in Figure 1, this pulverized coal preparation induction system comprises flour mill 8, is used for the coal dust separating mechanism with the grinding material separation of flour mill, coal dust separating mechanism upper end joins by dust arrester and air inducing mechanism 21, described coal dust separating mechanism is made up of mill separator 10 and the pulverized-coal collector 11 that joins with it, mill separator 10 joins with flour mill 8, and the lower end of pulverized-coal collector 11 and oscillating feeder 12 join; The upper end of pulverized-coal collector 11 and sack cleaner 20 join, deduster 20 tops and air-introduced machine 21 join, pulverized-coal collector 11 lower ends are connected to the oscillating feeder 12 that fine breeze is outputed to fine powder storehouse 13, and 13 bottoms, fine powder storehouse are connected to the single storehouse pump 17 that is used for weighing, stores fine breeze.
Operation principle of the present utility model is: the coal cinder in the coal cinder hopper 2 flows in the run coal bin 5 via oscillating feeder 3, elevator 4.The coal cinder of run coal bin 5 flows in the flour mill 8 via push-pull valve 6, disk feeder 7.Coal cinder is pulverize in flour mill 8.In the grinding process of coal cinder, by the rich CO of other industrial furnace 1 introducing
2Waste gas enters in the flour mill coal dust is dried.Coal dust after the oven dry enters mill separator 10 to be separated, and separates the fine powder that obtains and enters grade pulverized-coal collector 11, separates the pipeline of meal through automatic discharge valve 9 is installed that obtains and returns flour mill 8 continuation grindings.Pulverized-coal collector 11 separates the fine powder that obtains and directly enters fine powder storehouse 13 by oscillating feeder 12.Pulverized-coal collector 11 separates the superfine powder that obtains and enters deduster 20, and the coal dust dust of being collected by deduster 20 enters fine powder storehouse 13 through oscillating feeder.Air-introduced machine 21 is responsible for providing coal dust from the circulation power of flour mill 8 up to fine powder storehouse 13 whole links.Fine powder storehouse 13 is delivered to single storehouse pump 17 by push-pull valve 14, revolving plow reclaimer 15, tapered valve 16 with coal dust, single storehouse pump is provided with electronic scale 18 17 times, fine powder weight in the weighing pump, air accumulator 19 provide high-pressure inert gas that coal dust is delivered to the user along power transportation pipe in single storehouse pump 17.
