Description

DEVICE OF REMOVING DUST FROM AN INCINERATOR}

The present invention relates to the reduction and suppression of dust and dioxins generated in medium and small incinerators.In order to improve the efficiency of dust removal in incinerators and to make up for the shortcomings of the filtration group, a venturi is installed at the rear of the cyclone and the impeller in the venturi is installed. Its purpose is to adsorb dioxins by installing centrifugal force as impeller and dust collide, increasing the efficiency of dust removal, and installing activated carbon station inside the chimney at the upper part of redusting system.

Conventionally, when incineration of waste or other incineration in the incinerator, the waste is continuously put into the stocker.

At this time, due to the nature of the waste was tangled with each other, a large amount of input in a large chunk state.

And the stocker incinerator has a disadvantage that the combustion speed is slow and the combustion does not reach the maximum.

In other words, since the combustion performance is not good, the incineration may be burned for several hours later.

In addition, the fluidized-bed incinerator has the advantage that the combustion speed is fast and burns very well, but this is a disadvantage. This is because the combustion performance is good, and when the incinerator is injected into the fluidized bed, it is burned within a few seconds.

Therefore, if the quantitative quantity of the feeder for supplying the incinerators into the furnace is instantaneously massed in a bad or large agglomerated state, there is a problem that is connected to an imbalance of oxygen concentration in the combustion gas.

As such, when a large amount of waste is instantaneously introduced into a fluidized bed incinerator and a stalker incinerator, a large amount of waste is connected to an unbalanced oxygen concentration in the combustion gas. Hydrocarbons are emitted.

This produces dioxins, HCL, SO _X and NO _X and releases them directly into the stack.

In addition, in order to remove dust generated in small and medium incinerators, many cyclone dust collectors and filter dust collectors are currently used.

At this time, the performance of the cyclone dust collector is generally known to have a dust removal efficiency of about 50%, and the efficiency of the filtration dust collector is excellent, but there is a problem that a clogging phenomenon and a fire may occur in the filter.

The present invention aims to provide a method for economically and reliably treating wastes by drastically reducing harmful substances such as dioxin, reducing construction cost and operation cost by activated carbon government and impeller of dust removal device of incinerator.

Pretreatment Facility

It is a facility that collects and transports wastes, shreds them, performs pretreatment, collects and sorts out metals, and puts the remaining wastes into the incinerator.

(The first) incinerator

The incinerator injected by heating with an elevated burner is kept in high temperature and burned in a short time by the heat.

(Secondary) Incinerator

Gas, dust, and various foreign substances generated in the primary incinerator are reburned by the high temperature of the burner.

Air Cooled Heat Exchanger, Press Blower

The exhaust gas generated in the secondary incinerator is introduced by a press-fit blower formed in the air-cooled heat exchanger, so that the temperature of the exhaust gas drops.

Cyclone

The exhaust gas introduced from the heat exchanger separates and collects dust (dust) by applying centrifugal force to the impregnated gas by the rotational force of the cyclone dust collector.

Inlet blower

The exhaust gas generated in the cyclone is sucked and the gas is discharged to the redusting device formed in the stack.

Dust Collector, Impeller

The fine dust and gas flowed into the stack are collided with the impeller formed inside the redusting device, and the dust falls to the outer wall due to the centrifugal force.

(Secondary) Cyclone

The dust collided with the impeller is sucked back into the cyclone to separate the dust.

Injection blower

The dust separated from the secondary cyclone is sucked back and fed back to the stack.

Activated Tanggo Government

It is structured to connect with the redusting device, and its surface is divided into inner cylinder and outer cylinder. And between the inner cylinder and the outer cylinder is filled with activated carbon, hundreds of discharge grooves are formed on the surface of the inner cylinder to be fixed at the top of the stack and the exhaust gas can be discharged to the atmosphere through the exhaust pipe. A fixed hook is attached to facilitate opening and closing of the activated carbon fixing door.

Looking at the operation of the present invention configured as described above are as follows.

Incinerators 4 and 5 generate a large amount of smoke, dust, etc. together with various toxic gases.

At this time, the gas and odor generated from the incinerator (4), odor, soot, dust, etc. immediately flows into the second stage incinerator (5), the burners (2,3) is operated and burned by the heat.

Since the press-fit blower 7 fixed to the air-cooled heat exchanger 6 is continuously operated, the exhaust gas through the second stage incinerator 5 is strongly introduced into the air-cooled heat exchanger 6.

The introduced exhaust gas is separated into dust and gas due to the action of the primary cyclone 8.

At this time, dust is stored in a dust box and discarded.

The exhaust gas separated from the cyclone 8 is introduced into the stack 10 by the inlet blower 9 and collides with the impeller 12 attached inside the redusting apparatus 11. Due to this dust is generated centrifugal force hit the outer wall and fall to the bottom of the re-dusting device (11).

And dust not discharged into the atmosphere is introduced into the secondary cyclone (16) is separated into dust and gas by the action of the cyclone.

The exhaust gas separated from the secondary cyclone 16 is introduced into the stack 10 again due to the action of the injection blower 15.

Next, the exhaust gas through the impeller 12 again flows into the activated carbon government 13 and is discharged into the discharge groove 21 to decompose toxic substances (dioxin, etc.), thereby decomposing gas or harmless gas components with low density and harmless molecular composition. Is changed. After a predetermined time, the activated carbon exchange inside the activated carbon fixing unit 13 may be performed by separating the inner cylinder 20 in which the activated carbon is formed by opening the activated carbon fixing door 24.

In this way, the harmful gases are first and secondly decomposed by the cyclone, and the third is again adsorbed by the fine particles of the harmful gases by the impeller and the activated carbon fixing device. It is discharged to the inside.

As described above, the present invention is a device capable of reducing toxic gases generated in various combustion chambers and incinerators in a harmless gas and easily removing smoke, dust, and odors, and the natural environment caused by toxic gases (dioxin, etc.) and soot. And the destruction of ecosystems can be minimized, and by using the present invention formed in the stacks of incinerators, combustion furnaces, bathrooms, industrial plants, thermal power plants, etc., pollution pollution can be greatly prevented, and facilities are simple and economical. There are features that can be constructed by the method.
