Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved method for the continuous production of lamp blacks and an arrangement for implementing the method.

[0002]

2. Description of the Related Art Lamp black has been used as a raw material for black ink since ancient times, and in recent years, it has been widely used as a pigment, a colorant, a carbon material, a rubber mixed material and the like.

The conventional manufacturing method of this lamp black is as follows.
It has been carried out by an apparatus in which one to two combustion furnaces and 6 to 12 collecting and settling chambers are connected in series.

This conventional example is shown in FIGS. In the illustrated conventional apparatus 45, a first settling chamber 50, a second settling chamber 51, a third settling chamber 52, a fourth settling chamber 53, and a fifth settling chamber 54 are provided in a combustion furnace 46.
And each of the sixth settling chambers 55 are connected in series, and the sixth settling chamber 55 communicates with the chimney 59. Further, the combustion furnace 46 is provided with a combustion dish 47, 48 is an opening for taking in outside air, 49 is an outlet of the furnace provided in the upper part of the combustion furnace 46, and leads to the inside of the first settling chamber 50. Further, 56 is a guide port connecting between the sedimentation chambers, and 57 is an outlet for taking out the carbon powder accumulated from the sedimentation chambers. Reference numeral 58 is a door that opens and closes this outlet.

In the conventional device 45, when the raw material oil supplied to the combustion tray 47 is ignited, the pyrolysis gas (that is, oil smoke) generated by the combustion of the raw material oil is discharged from the first settling chamber 50 to the sixth settling chamber. It flows through the settling chamber 55 through each inlet 56 in order, and is finally discharged from the chimney 59 to the outside. During this distribution process, carbon powder contained in the pyrolysis gas is appropriately settled and deposited in the corresponding settling chamber.

The burning time of the raw material oil in the manufacturing process of this lamp black is generally 8 to 20 hours, and the door 58 is used for the carbon powder accumulated in each settling chamber.
It was collected by the means of opening and scraping it out manually.

[0007]

In the case of the above-mentioned conventional apparatus, the outlet temperature of the combustion furnace 46 is about 400 to 1250 ° C, although it varies depending on the season, and the settling chambers 50 to 5 are used.
Near the exit of 5, 600-800 ℃, 200-300 ℃, ...
・, 100-120 ℃, 60-80 ℃ Therefore,
In particular, in the fifth settling chamber 54 and the sixth settling chamber 55, the temperature decreases, so that the proportion of moisture and other volatile components generated during the combustion of the feedstock oil that are adsorbed by the settling carbon powder increases. Therefore, the carbon powder obtained in the first and second settling chambers 50 and 51 and the carbon powder obtained in the fifth and sixth settling chambers 54 and 55 respectively have a large difference in quality. It will be.

Further, particularly when the constituent material of each of the sedimentation chambers 50 to 55 is a heat-resistant brick, impurities generated from the brick are also mixed into the carbon powder, and the quality of the lamp black obtained can be improved. It will also lower it.

Further, since the temperature in the above-mentioned settling chambers greatly depends on the season, it is difficult to obtain lamp black of a constant quality throughout the year.
The quality of lamp black varies depending on the type of raw oil (eg vegetable oil, mineral oil, liquid, solid, etc.) and the shape of the combustion furnace, and also depends on the thermal decomposition rate of the raw oil during combustion. It depends. That is, relatively large particles are obtained when the flame is large, and relatively small particles are obtained when the flame is small.
The particle size becomes large in the range of 0 mμ.

Since the size of the particles of the lamp black thus obtained depends on the size of the flame, two or more combustion furnaces are required for mass production, but the combustion state of the feed oil in each combustion furnace is balanced. Keeping well is difficult. If the balance of the combustion state cannot be maintained, the quality of the obtained lamp black cannot be made uniform.

Further, when two or more combustion furnaces are installed in the conventional apparatus configuration, abnormal combustion in one furnace causes an abnormally high temperature especially in the first settling chamber to ignite carbon powder deposited in the chamber. Accidents may occur. In this case, even if the fuel supply to the furnace was stopped, the ignition in the settling chamber could not be extinguished until the raw material oil remaining in the combustion tray was completely burned out, and there was a drawback that the treatment took a long time. .

Further, the carbon powder is collected from each settling chamber
As described above, it was necessary to perform the scraping work by hand, but the work itself is extremely difficult and heavy labor, and therefore it is difficult to secure workers, and the treatment of the carbon powder after scraping is also easy. It wasn't something.

Therefore, in the present invention, the above-mentioned drawbacks are eliminated, lamp black of particularly uniform quality can be obtained throughout the year, and the lamp black can be continuously mass-produced without any difficult work. An object of the present invention is to provide a manufacturing method and a device therefor.

[0014]

In order to achieve the above-mentioned object, the present invention has the following structure for a continuous production method of lamp black. That is, the pyrolysis gas accompanying the combustion of the feedstock oil in one or more combustion furnaces is forcibly concentrated immediately from the outlet of each of the above-mentioned furnaces at one location, and the collected pyrolysis gas is cooled, and this cooling is performed. The pyrolyzed gas generated is introduced into the cyclone type collector, the carbon powder generated in the pyrolyzed gas is accumulated in the lower part of the cyclone type collector, and the deposited carbon powder is successively and continuously discharged to the outside. It is characterized by discharging.

In the above-mentioned production method of the present invention, the combustion furnace and the feedstock oil can be those used in the conventional method. As the raw material oil, various kinds such as vegetable oil, mineral oil, liquid and solid can be used.

Further, the forced concentration of the pyrolysis gas from the combustion furnace can be carried out by, for example, an exhaust fan provided on the pipeline.

Further, in the above-mentioned production method according to the present invention, in order to completely remove the carbon powder contained therein, a step of introducing the gas from the cyclone type collector into the back filter or the electrostatic precipitator may be included. Good.

The above-described manufacturing method of the present invention can be carried out by the following continuous manufacturing apparatus for lamp black of the present invention. That is, one concentrating chamber and one or more combustion furnaces arranged in the outer peripheral part of the concentrating chamber are configured to communicate with each other at the upper part thereof, and from the bottom part of the concentrating chamber. It is characterized by comprising a cooling tower communicating with each other, and a cyclone type collector which communicates with the inside of the cooling tower via an exhaust fan.

In the above-described manufacturing apparatus of the present invention, the gas concentrator may be configured such that each combustion furnace is separated from the concentration chamber, and the outlet of each combustion furnace communicates with the concentration chamber through the duct. Also, each combustion furnace and the concentration chamber may be integrally configured.

Further, from the viewpoint of making the temperature of the pyrolysis gas from each combustion furnace uniform, it is preferable that each combustion furnace is arranged at a uniform position on the outer peripheral portion of the concentration chamber.

Further, in the case of being constituted by a plurality of combustion furnaces, the cross-sectional shape of the concentrating chamber may be circular, square, triangular or the like, which is suitable for evenly arranging the respective combustion furnaces.

The concentration chamber itself can be formed by using a heat-resistant material (for example, heat-resistant brick) as a base material, but the inner surface portion of the formation material component is not damaged by thermal decomposition due to high temperature heating around 1200 ° C. It is preferable that at least it is coated with castable amorphous refractory material.

Further, the inner surface of the concentration chamber may be formed to have a smooth sloping surface that expands upward in a hopper shape so that carbon powder in the inflowing pyrolysis gas does not accumulate and remain inside. it can. Further, in this case, the slope of the slope is 40 to 80 ° with respect to the horizontal plane because of the flowability of the carbon powder contained in the pyrolysis gas to the next step and the uniform inflow of the pyrolysis gas from each combustion furnace. The angle is preferable. Also, the communication from the bottom of the concentration chamber to the cooling tower can be by means of a conduit made of, for example, a refractory material that can withstand a temperature of about 300 ° C.

Although a general heat exchanger can be applied to the cooling tower, the carbon powder contained in the gas adheres to the inner surface of the cooling tower because the hot pyrolysis gas is rapidly cooled here. Therefore, it is desirable to have the following configuration in order to deal with the adverse effect that the cooling tower is blocked.

A suitable cooling tower configuration in this case is as follows.
For example, 180-240 mmφ metal (for example, stainless steel)
It is possible to employ a structure in which a plurality of pipe members are arranged in a row in a row at equal intervals so that the insides of these pipes communicate with the above-mentioned concentration chamber. Also, by constantly flowing a constant temperature air flow or refrigerant in the gap between these cooling tubes,
It is possible to stabilize the cooling of the pyrolysis gas flowing in the cooling pipe and adjust the cooling temperature thereof. Further, it is preferable that the inner surface of the bottom portion of the cooling tower which communicates with these pipes is formed by a hopper-shaped inclined surface for the same reason as that of the inner surface of the concentration chamber described above.

Further, in the above-mentioned structure of the cooling tower,
An opening / closing device capable of opening / closing the upper opening of each tube may be provided. As the opening / closing device, for example, a device having a shaft portion that is expanded and contracted by an electromagnetic force and a valve plug that is fixed to the end of the shaft portion and that can be closed by extending to a corresponding pipe opening portion at the time of extension can be adopted. .

Further, the exhaust fan can be arranged so that the exhaust air force extends along the pipeline from the cooling tower to the collecting and settling chamber. The wind power of this exhaust fan acts not only on the inside of the cooling tower but also on the central chamber, each combustion furnace, and the cyclone collector in the subsequent process, and the collectors such as the back filter. It even affects the condition. Therefore, it is preferable that the amount of air and pressure can be obtained such that the flow rate of the pyrolysis gas is sufficient for the flow of the pyrolysis gas, including the combustion state of the raw oil and the generated carbon powder.

Further, the discharge end of this blower is constructed so as to communicate with the upper part in the cyclone type collector through a pipeline. The cyclone type collector causes a swirling flow in the cyclone by the above-described exhaust fan, and the centrifugal force thereof causes the carbon powder particles contained in the gas to be forcibly collected and deposited at the bottom of the cyclone. Function.

Further, in this cyclone type collector, the carbon powder deposited on the upper side can be successively and continuously discharged by, for example, a rotary valve device provided in the lower discharge part of the cyclone.

Since the waste gas at this stage still contains a relatively large amount of carbon powder, a back filter or an electrostatic precipitator is further provided so that it can be introduced through the above-mentioned waste gas opening. Can be connected.

As this back filter, it is preferable that, for example, a filter member is incorporated and the carbon powder filtered by the filter member is allowed to be sequentially precipitated and sent out to the outside. This is because this carbon powder can also be a product.

Further, the carbon powder thus sent out is collected under a cyclone type collector and, in some cases, below a back filter in an appropriate receiver, for example, a trolley receiver. It can be configured to be carried outside or enclosed directly in the bag.

[0033]

In the present invention, the following actions are exhibited. First, when the pyrolysis gas generated in the combustion furnace is forcibly immediately flowed into the concentration chamber from the exit of the furnace and concentrated, the carbon powder content in the pyrolysis gas is cooled in an averaged state. It can be introduced into the tower.

When two or more combustion furnaces are involved, the carbon powder content and the gas temperature of the pyrolysis gas from each combustion furnace are also averaged. In this case, the concentrated inflow of the pyrolysis gas into the central chamber is forcedly executed by, for example, an exhaust fan, and at this time, the wind force generated by the exhaust fan also acts on each furnace through the central chamber. Also, it acts to make the combustion state of the raw material oil in each combustion furnace uniform.

The thermal decomposition gas thus concentrated is introduced into the cooling tower from the concentration chamber. In this case, if the inner surface of the concentration chamber is coated with a heat-resistant inert material,
In this process, no impurities are mixed in from the constituent members. Further, when the inner surface of the concentrated chamber is formed by the slope of the hopper, the carbon powder is not particularly accumulated in the chamber.

The introduced pyrolysis gas is cooled in the cooling tower. Normally, 200 when introduced into the cooling tower
After cooling to a gas temperature of ˜300 ° C., it is preferable to be in a cooled temperature state up to a temperature range of 140˜180 ° C.

If the cooling tower has a plurality of metal pipes arranged in a column and is provided with an opening / closing device capable of opening and closing the upper openings of the respective pipes, the pipe openings are Adjusting the amount of gas flowing in the cooling tower according to the number of open, controlling the combustion state of the feedstock oil in each combustion furnace by this and dust, the temperature after cooling to the pyrolysis gas in the cooling tower Can be adjusted. When this cooling tower is configured with a spare cooling pipe, by using the spare cooling pipe instead of the regular cooling pipe,
It is also possible to deal with accidents such as clogging of the cooling tower due to the adhesion of carbon powder.

Further, in the above-mentioned structure of the cooling tower,
By adjusting the open state of the valve of the above-mentioned switchgear and changing the flow velocity of the gas flow in the cooling pipe, the action of forcibly removing the carbon powder adhering to the inside of the pipe and improving the cooling effect is also exhibited. It

The cooled pyrolysis gas introduced into the cyclone type collector is subjected to the centrifugal force of the swirling flow in the cyclone, and the carbon powder contained therein is forcibly deposited in the lower part of the cyclone. This accumulated powder can be sequentially discharged to the outside by a rotary valve device or the like.
