Description

Recirculating Gas Combustion Furnace {CONFLUENCE GENERATION GAS INCINERATOR}

The present invention is a rear end equipment of a vacuum incinerator in which the waste is pyrolyzed by indirect heating in a vacuum state instead of a direct fire method, and receives and burns the pyrolysis gas generated in the incinerator to discharge the gas pipe on the coil. And a combustion-generating gas combustion furnace which improves the combustion rate by being brought into contact with the outer surface of the heating tube during the return flow by centrifugal force in the combustion furnace during discharge through the gas outlet.

The general form of the furnace is provided with an inlet for receiving the heating gas into the furnace and an outlet for discharging the burned gas, one side is provided with a burner which is a heat source for burning the gas.

However, in the conventional combustion furnace, the heating gas stays in the combustion furnace in a short time and is discharged in a state where it is not sufficiently combusted. Therefore, a separate purification device must be provided as a post-treatment process. Unconsumed gases were released into the atmosphere, resulting in environmental pollution.

Accordingly, the present invention was created to solve the above problems, an object of the present invention is to pass the pyrolysis heating gas generated in the vacuum incinerator for waste treatment through a heating tube installed inside the combustion furnace, the heating tube Has a gas inlet at the top of the combustion furnace and a discharge port at the bottom of the combustion chamber to wind up the coils in a plurality of heaters formed radially on the inner surface of the inner cylinder to burn the gas while passing through the inside of the heating tube. Is to provide a circulating generated gas combustion furnace which is brought into contact with the outside of the heating tube during the reciprocal rise by the centrifugal force to be combusted again to enable complete combustion.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing the structure of a combustion furnace according to an embodiment of the present invention, Figure 2 is a cross-sectional view of the A-A portion of FIG.

Referring to FIGS. 1 and 2, the combustion furnace 1 includes an outer cylinder 10 having a lower end, an inner cylinder 20 installed in the outer cylinder, and a base 30 coupled to the lower end of the outer cylinder 10. It is composed of

On the upper end of the outer cylinder 10 and the inner cylinder 20, a vacuum suction port and a gas discharge port 16 are formed in communication with each other, and an inner heat shield plate which blocks the lower part of the inner cylinder 20 from the inner cylinder 20 so as to be separable therefrom. 23 is provided, and a first discharge port 22 through which ash generated by gas combustion is discharged is provided at the center of the internal heat shield plate 23.

In addition, a suction port 15 is provided at one side of the outer cylinder 10 to allow the first space S1 formed between the outer cylinder 10 and the inner cylinder 20 to maintain a vacuum state, and at an inner circumference of the inner cylinder. As shown in FIG. 2, a plurality of radial heaters 21 are formed vertically.

The heating tube 12 provided inside the inner cylinder 20 is coiled and wound to contact the plurality of heaters 21, respectively, and an upper end thereof is pyrolyzed and discharged from a vacuum incinerator (not shown) outside the outer cylinder 10. An inlet 13 for accommodating the heating gas is provided, and the other end is provided with a discharge port 14 for discharging the heating gas.

At this time, the discharge port 14 is preferably located at any point in the inner / bottom of the inner cylinder 20, which will be more apparent in the description of the operation described later.

On the other hand, the base 30 is coupled to the open surface of the lower end of the outer cylinder (10).

The structure forms a flange 11 at the bottom of the outer cylinder 10, and forms a base 30 that is fastened by fastening means such as bolts / nuts to correspond to the flange 11, the center of the base 30 The second discharge port 31 is provided with a second discharge port 31 for discharging the ash discharged from the first discharge port 22 to the outside again, the inside of the second discharge port 31 is maintained in a vacuum state A second space S2 is provided, and although not shown, a suction port for sucking air in the second space S2 is provided to achieve a vacuum state simultaneously with the first space S1.

The base 30 may be separated from the outer cylinder 10.

Therefore, when a failure occurs or needs cleaning in the combustion furnace 1, when the base 30 is removed from the outer cylinder 10, the inner cylinder 10 is opened, so that repair or cleaning may be performed through the inner cylinder 10.

To help understand the description, the following describes the gas combustion action of the combustion furnace of the present invention.

First, by operating a vacuum pump (not shown) to suck the air inside the first space (S1) and the interior of the inner cylinder 20 through the suction port 15 to maintain a vacuum state, and also by the same action Inhalation of the air in the second space (S2) provided in 30) to maintain the vacuum state to insulate the outside of the combustion furnace, and absorb the air in the combustion furnace through the gas outlet 16 to burn Vacuum the inside of the furnace.

Thus, when the heater 21 is operated in the state in which the inside of the combustion furnace 1 maintained the vacuum state, the heating tube 12 connected with the heater 21 is heated at high temperature by heat conduction, and the combustion furnace ( 1) Let the inside be 800 degreeC or more.

Temperature measurement inside the combustion furnace (1) can be measured and confirmed through the thermometer (17) fixed to the outer cylinder 10 and the inner cylinder (20).

At this time, the inside of the combustion furnace (1) is maintained in a high temperature, but as the first space (S1) and the second space (S2), the outside of the combustion furnace (1) is surrounded by a vacuum layer, so the entire internal high temperature is a combustion furnace (1) It can be blocked from being transmitted to the outside.

On the other hand, when the internal temperature of the incinerator 1 rises to an appropriate temperature at which the gas can be incinerated, the heating gas is introduced through the inlet 13 so that the heating gas passes through the heating tube 12.

At this time, the heating gas is burned while being in contact with the inner surface of the heating tube 12 which rises at a high temperature, and at the same time, the heating gas discharged to the discharge port 14 generates centrifugal force while passing through the heating tube 12 on the coil to form the inner cylinder 20. As it flows from, it rises.

Therefore, the heating gas which flows up in a flow is secondary combustion while contacting the outer surface of the heating tube 12 and the surface of the heater 21, and perfect combustion is possible.

The burned heating gas is discharged through the gas discharge port 16, and ashes generated by the combustion are discharged through the first and second recirculation outlets 22 and 31 for disposal.

As can be seen from the above description, according to the spin-generating gas combustion furnace according to the present invention, the pyrolysis heating gas generated in the vacuum incinerator for waste treatment is passed through a heating tube installed inside the combustion furnace, and the heating tube is radial. Since the heating gas is wound on the coil formed by the coil, the heating gas is first combusted while passing through the inside of the heating tube, and at the same time, the rotary centrifugal force is generated, and the discharged gas is again in contact with the outside of the heating tube while the flow of gas flows back inside the inner tube. do.

Thus, not only does the heating gas stay in the combustion furnace for a long time, but also makes direct contact with the inside / outside surface of the heating tube during the stay so that more complete combustion can be achieved, which eliminates the need for a purification device in a post process. In addition to saving equipment costs, it has the effect of preventing environmental pollution.

In addition, since the base can be separated / combined with the outer cylinder, when the internal failure of the combustion furnace or the base is removed during cleaning, the interior of the combustion furnace can be easily opened.
